Introduction to Dry Slag Treatment

The slag produced by garbage incineration contains a certain amount of heavy metal substances such as iron, copper, zinc, chromium, etc., which has recycling value and can be used as a resource for development and utilization. Generally, the thermal ignition loss rate of slag is about 1.4%-3.5%, and the low thermal ignition loss rate reflects its good incineration effect. Untreated incinerator slag is mainly composed of slag, glass, ceramic fragments, iron, and other metals. Among them, large-particle slag (>30mm) is mainly ceramic/brick and iron, and the mass percentage of the two substances decreases with the decrease of particle size; small-particle slag (<30mm) is mainly slag and glass Its content increases with the decrease of the particle size, which is mainly caused by the physical properties of these substances and the impact force experienced when they move in the grate.

Generally, a dry slag processing system includes a feeding receiving unit, a screening unit, a crushing unit, a transfer unit, a dust removal unit, and so on. This 3D model is a process flow of dry slag treatment.

9 Ways to Recycle Waste

Waste recycling is a broad field. Over time, we have been continuously researching and developing waste management. Improving the methods of collecting, distributing and disposing of the waste is always an important task to help protect environmental interests and maintain our growing population.

Reuse can reduce the consumption of crude oil raw materials and restore the extra vitality that manufacturers will use when preparing new products. Reuse can also reduce the number of materials that enter the landfill, which is a major bonus because many countries are rapidly reducing wasted space. Fortunately, reuse is easy and will soon become part of your typical plan.

Let it decay

You may be surprised here because simply letting the garbage rot over time produces energy that we can use. Even in the composting process, this organic waste is essentially allowed to produce methane when it decomposes. Similarly, a large amount of waste material produces methane gas, which can be stored and converted into fuel. In other words, there are more effective and faster ways to convert waste into energy, especially large-scale waste.

Burn it

Almost anything can be burned to produce a kind of energy, as is a waste. The incineration of solid waste produces heat energy, which we can then use to turn turbines and generate electricity.

Although relatively efficient, this process generates many pollutants and omissions that may harm the environment. Therefore, although there are many different incineration plants across Australia, they are strictly regulated in Australia and strict rules must be followed to ensure safe operation.

Co-fire

There is no doubt that you have heard of the potentially harmful effects of burning coal. Co-firing involves burning coal and biomass (or waste) together to produce energy. This approach is more environmentally friendly than just burning coal, and more effective and more effective than incineration of garbage. This approach has been adopted in many countries around the world.

Gasification

Gasification is a more effective method of converting waste into energy because it does not require combustion and therefore is a cleaner process. Heat the waste with a certain amount of oxygen and steam in a controlled environment. The chemical reaction that takes place produces a gas, which is essentially a fuel in itself but can also be converted into a liquid.

The power generated by gasification is renewable energy, which has many advantages compared with incineration. On the one hand, the incineration of waste produces energy by using a steam cycle. However, the gas turbine used in the gasification process is more efficient. In fact, the efficiency of the gasification process is about twice that of incineration, and it is more environmentally friendly.

Worm farming

Through worm breeding, the amount of natural waste sent to landfills can be reduced. Worms provide us with great management by transforming additional sustenance into nutrient-rich castings. These castings can be used for top dressing around plants, nourishing indoor plants, and adding to the soil. The liquid "tea" provided by the worm can be used as compost, or it can be weakened and added to potted plants or used in your garden.

Compost

The composting project can convert natural waste including vegetable fragments and garden waste into high-quality manure, which can be used as a unique compost for composting, thereby enhancing the garden. Natural materials are confined in the stool container, where conditions can be controlled to speed up and optimize failures. The micro-living creatures in the soil, nightcrawlers, and creepy crawlers help separate the natural waste in the fertilizer tank.

Recycling e-waste

The amount of e-waste delivered is three times that of a typical household unit’s waste. It may contain harmful substances such as lead, mercury, cadmium, hexavalent chromium, and brominated flame retardants, which are dangerous, difficult to discard, and may harm the earth.

Although a large amount of e-waste is transported to landfills, more garbage is retained in organizers, carports, storage rooms, and retirees across Australia – this means we need to continue to mine the soil instead of repeating it on the ground Use all valuable materials in old innovations. Following these lines of thinking, for every new innovation you invite you into your home, you should focus on reusing the two bad parts. We call it "1-2 steps" or "one in and two out".

As you can see, there are many ways to use waste and obtain energy from it, rather than simply processing it.

Characteristics of Garbage Sorter

With the increase of the urban population, waste sorting machines have become popular in many countries. Recently, municipal waste has shown an increasing trend. Facing the large amount of waste generated by human beings, how do we quickly realize the classification of waste? The answer is a fully automatic garbage sorter. This kind of recycling equipment makes garbage sorting easier. At the same time, the machine will save a lot of labor costs.

The garbage sorter is designed based on the principle of reducing the volume of garbage and turning waste into treasure. By using various efficient garbage sorting systems, we can obtain organic, plastic, metal, brick, stone, etc. from the garbage. The classification rate of the above garbage can reach more than 85%, and the classification rate of film plastic can reach more than 90%.

Do you know the characteristics of the Sorting machine MSW china?

1. Rotating screen machine. The rotary screen machine is mainly used to select large materials larger than 50mm and small materials smaller than 50mm. This process effectively divides waste into two types. In addition, according to the different needs of customers, we can also add blades inside the rotary screen to achieve the breaking effect.

2. Smooth automatic document feeder. This paper feeder can automatically transfer the garbage to the next garbage sorting process, thus saving manpower. In addition, the machine can evenly distribute garbage on the belt, so that the next operation is more smooth.

3. PLC system. The PLC control system can monitor the entire working process of the solid waste management system. Once anything unpredictable happens, we can make adjustments in time. Therefore, the machine greatly guarantees the safety of the garbage sorting equipment.

4. Comprehensive winnowing machine. The comprehensive winnowing machine adopts several garbage classification principles, such as specific gravity method, volume method, cyclone separation method, etc. Waste is mainly divided into three types: plastic film and mixed materials (hard plastic, rubber products, miscellaneous paper). , Textiles, etc.) and heavy objects (bricks, stones, rubber overshoes, glass, etc.). After being processed by this garbage classifier, the sorting rate is greatly improved.

What materials can be sorted from garbage? What can these classified materials do?

As we all know, garbage is composed of plastic, tree branches, chicken manure and other different wastes. In different countries, there is a big gap between the composition of waste. We want to know your detailed information and will design a suitable solid waste recycling plant for you.

1. Waste plastic. There are three ways to recycle waste plastics. The first is to use a waste plastic pyrolysis machine, which can turn plastic into oil. Secondly, certain materials in plastics can be used as rubber reinforcing agents. Third, we can sell waste plastics to other industries to make new plastic products.

2. Stone, sand, and waste building materials. Do you think these wastes are useless? However, we can use these wastes to make bricks through the brick machine production line. Nowadays, the technology of making bricks from the mud, stones, sand or carbon black in pyrolysis garbage is fully mature.

3. Organic matter. After selecting some unusable materials, we can send the organic matter to the fermentation system, and then the system will produce biogas as energy.

4. Scrap metal. After packaging with a packaging machine, scrap metal can be sold directly to other industries to manufacture new metal products.

Criteria for Good Garbage Classification

So far, there is no scientific and unified criterion for judging whether the garbage classification is good or not.

How much waste is sorted out and reduced through waste sorting equipment, or how much money is spent sorting out a tonne of waste? We will find that some places have spent tens of millions of yuan for several years, but only tens of thousands of tons of renewable resources are recycled (not including kitchen waste). Calculated according to the cost of recycling per ton, up to a few thousand or even tens of thousands of yuan per ton, such an approach is definitely unsustainable and unrepeatable.

The key issue is that, in the end, it was discovered that after several years of garbage classification, the effect of garbage classification was not obvious, and there were no obvious “beneficiaries”. The "benefits" here are mainly economic benefits. In the end, everyone was busy, and until the end, everyone was tired but to no avail.

So what are the real criteria for classifying rubbish? According to Waste Sorting Machine MSW China Manufacturer; There are three criteria:

First, whether it is conducive to sustainable and harmless household garbage, recycling, and source reduction.The so-called sustainable means that it can continue continuously, which requires low operating costs and not excessive financial input. Harmlessness is the foundation, and resource recovery is the guarantee, that is, how much waste is allocated for recycling treatment and utilization and no longer enters landfill sites. In the documents of the Ministry of Housing and Urban-rural Development, the utilization rate of classified resources reaches 35%. The key is to reduce the front source, which can be promoted or pushed back by garbage classification. For example, the daily amount of garbage per person can be reduced from 1.12 kg before to 0.39 kg in 2009 by garbage classification, which can be reduced by 65%. Through garbage classification, South Korea produced 2.3 kilograms of waste per capita per day in 1995, compared with 0.95 kilograms in 2006, a decrease of 58.7%.

Second, is it beneficial to the residents' sense of gain and happiness? First clarify the attributes of garbage, because garbage is a pollutant, you should first pay; because it is sorted, you should pay for labor, and you should have income, especially economic income. However, due to historical reasons, the previously mixed waste treatment fee was not charged or not charged in full, so the income through waste classification and reduction cannot be reflected. This situation needs to be corrected and becomes "multiple mixed wastes. Charge, sort garbage, and pay less". At the same time, the residential environment of the community has become tidy and clean due to garbage classification, which improves the beautification of the living environment, and the residents have a sense of gain and happiness.

Third, is it conducive to reducing the overall government financial input? When garbage sorting starts, the government needs to increase investment appropriately, but from a long-term and overall perspective, as garbage is recycled and the source is reduced, the garbage removal and disposal fees will be reduced, and the service life of the back-end factories will be extended. This will produce economic benefits. Therefore, the success of garbage classification will not only produce ecological and social benefits, but also industrial economic benefits.

Why Do We Need A Biogas Plant?

Biogas is advertised by some as indispensable to creating around the economy, however just how advantageous is it as a power source? Do we need a biogas plant?

1. What is biogas energy?

Biogas is a kind of biofuel that is normally produced from the decay of organic waste. When raw material, such as food scraps as well as pet waste, breaks down in an anaerobic setting (an atmosphere lacking oxygen) they release a blend of gases, mainly methane as well as co2. Because this decomposition occurs in an anaerobic setting, the process of producing biogas is likewise known as anaerobic digestion.

2. Why choose marsh gas?

By transforming natural waste into energy, biogas is making use of natures sophisticated tendency to recycle substances into efficient resources. Biogas generation recoups waste products that would certainly or else contaminate landfills; stops using toxic chemicals in sewer treatment plants, and also conserves money, energy, and also material by treating waste on-site. Furthermore, biogas usage does not need fossil fuel removal to create power.

Instead, bio gas takes a problematic gas as well as converts it into a much safer type. Much more particularly, the methane material present in decaying waste is exchanged co2. Methane gas has about 20 to 30 times the heat-trapping capabilities of co2. This implies that when a decomposing loaf of bread converts right into biogas, the loafs environmental influence will certainly have to do with 10 times less potent than if it was delegated rot in a landfill.

Biogas Plant

3. Functioning of a Biogas Plant

The fresh pet manure is stored in a collection storage tank before its handling to the homogenization storage tank which is equipped with a mixer to promote homogenization of the waste stream. The consistently mixed waste is gone through a macerator to acquire a consistent particle size of 5-10 mm as well as pumped into suitable-capacity anaerobic digesters where the stabilizing of natural waste happens.

In anaerobic food digestion, natural material is converted to biogas by a collection of bacteria teams into methane and also carbon dioxide. The majority of commercially running digesters are plug flow as well as complete-mix activators operating at mesophilic temperature levels. The type of digester utilized differs with the consistency and also solids content of the feedstock, with capital investment aspects, and also with the key purpose of food digestion. Biogas consists of a substantial quantity of hydrogen sulfide (H2S) gas which requires to be removed off due to its extremely corrosive nature. The removal of H2S happens in an organic desulphurization system in which a minimal quantity of air is added to biogas in the visibility of specialized cardiovascular bacteria which oxidizes H2S into essential sulfur.

4. Advantage of bio gas plant.

Biogas plants depend on anaerobic food digestion, a fermentation procedure in which waste is absorbed by microbes to create methane gas (biogas). The waste can be converted into biofertilizer and also spread directly onto fields, or the biogas itself can be utilized reciprocally with natural gas .

Biogas could be especially beneficial in-country or poorer areas due to the affordable set-up as well as the schedule of waste materials. Virtually any kind of organic waste can be made use of while doing so, though aspects such as pH and also temperature level influence gas manufacturing.

5. The path to a circular economy

Sourcing power from biogas seems an excellent option to two problems faced in the modern globe: mounting waste as well as the requirement to rapidly decarbonize in the face of increasingly unpredictable international temperatures.
