Garbage Drying and Mechanical Sorting

At present, due to the rapid development of China's economy, and the high concentration of urbanization, the rapid growth of urban domestic waste brought urban managers by surprise. To quickly solve the current waste problem, China is vigorously promoting and encouraging waste incineration power generation technology. However, due to concerns about the discharge of pollutants such as dioxin, the support, and understanding of the people in some places are still not available, which has caused a series of social conflicts. Behind the vigorous promotion of the waste incineration project, what is really worrying is that, without sorting, recycling and selection, garbage cannot "turn waste into treasure". Under such circumstances, in what way should garbage disposal move towards benign development? China Automatic Waste Sorting Equipment

Domestic garbage has large water content, dehydration and drying and sorting make garbage incineration more efficient

As the front-end technology of waste treatment, waste sorting technology is an indispensable link for the reuse of resources and the subsequent processing chain of waste treatment. Especially in the chain of waste incineration, sorting technology is particularly important. 

China Automatic Waste Sorting Equipment

Garbage sorting can not only improve the utilization rate of resources and realize the reuse of resources but also improve the efficiency of garbage incineration

The Chinese sorting machine MSW manufacturer believes that the biggest problem faced by a domestic garbage disposal is the high moisture content of garbage. In some areas, garbage moisture content is even greater than 50%. The high moisture and low calorific value of domestic garbage are very incinerated difficult. Many waste incineration power plants leave garbage in the original garbage storage for a few days before incineration to remove some of the leachate (moisture) inside. In this process, they will naturally go through an anaerobic reaction process and emit more harmful gases. Increase the cost of leachate treatment. In addition, in order to increase the calorific value of waste incineration, waste incineration plants will be mixed with coal and burned together, which not only increases the cost, but also generates additional greenhouse gas emissions. Therefore, in order to increase the calorific value of garbage incineration, reduce costs, and reduce harmful gas emissions, the key is to dehydrate the garbage to dry.

Garbage drying is an important first step in the garbage disposal process. Sorting garbage after it is dried is called resource pretreatment before garbage incineration. Wet garbage cannot be used as a resource with market value, and can not separate inert substances, pollutants, and combustibles well; due to moisture, a large amount of organic matter makes the adhesion between garbage particles very strong, that is, using modern automated sorting The mechanical effect is not very ideal, and the equipment is seriously blocked.

Fully automated mechanical sorting is to sort out the electronic fragments, iron and non-ferrous metals in the dry garbage for recycling; and then separate the incombustible substances, that is, inert substances, such as glass, sand, stone, ceramics, etc. These inert substances Can be used for road construction. The remaining combustible materials, such as plastic, wood, paper, cardboard, cloth, and organic matter, can be made into RDF, that is, garbage-derived fuel, or solid recycled fuel. After the incombustibles are dried, the RDF/SRF has a high heating value and can be fully burned by itself without adding any auxiliary fuel.

The treatment technology of the project can realize that the daily mixed domestic waste is directly made into a composite fuel with a calorific value of 3000-3500 kcal by the domestic waste treatment system. There is no smoke, sewage, and dioxin emission during the whole treatment process. Drying waste materials and finished fuels are carried out at low temperature (not exceeding 150 degrees), and only produce water vapor. Water vapor is sent to the deodorizing tower through the pumping device and discharged after being deodorized by the water curtain. The sewage used for deodorizing treatment is discharged into the sewage treatment tank through the pipeline for treatment and recycling.

The Development Prospect of Garbage Sorting Equipment Is Very Optimistic

As the urban population continues to increase, people's living standards also continue to improve, and the resulting domestic waste is also increasing. In the process of urbanization, garbage as a product of urban metabolism has become a burden for urban development, and basically garbage is still stacked in the open air, and the harm to the environment has become increasingly serious. Therefore, environmentally friendly and economical disposal of urban domestic waste has become a very urgent task. Existing garbage disposal methods include discarding to land, discarding to rivers and oceans, landfilling, composting, incineration, and recycling.

At present, most waste disposal is mainly based on landfills, accounting for more than 70% of the total treatment volume. Most countries in the world, especially the majority of waste treatment in underdeveloped countries use this method. This method is characterized by low construction and operating costs, simple operation, and large processing capacity. But there are also many disadvantages: First, it takes up a lot of lands, it is difficult to select a site, and the cost of land acquisition is high; Second, a lot of waste is contained in the waste, and the waste is artificially turned into "a resource that cannot be grown, a huge amount thrown away. "Wealth" cannot meet the requirements of resource treatment; third, the environment is seriously polluted. Because the existing landfill construction is too large to meet the requirements of a sanitary landfill, the bacterial toxins in the garbage continue to leach downward, polluting the land and water quality, and with the increase of accumulation and the continuation of time, the pollution spreads to the surrounding and underground deep layers. After thousands of years of damage, the poisonous and smelly gas emitted by the garbage diffuses around, forming three-dimensional pollution in the air, surrounding and underground. Although a few "sanitary landfills" have been built in many developed countries and some more developed cities in my country to reduce some pollution, the environmental pollution problems caused by technical imperfections are still many and cannot be solved fundamentally.

Therefore, the advantages of the municipal waste sorting machine are highlighted. The garbage sorting equipment is used to recycle domestic garbage into resources, and the urban domestic garbage is accurately classified, and then the appropriate ones are used according to the different properties of the classified garbage. The method should be treated so that it can be recycled and reused, so as to truly achieve the harmlessness, reduction and harm reduction of garbage, and at the same time, it can also reduce the demand for natural resources and realize the sustainable use of resources. Therefore, the development prospects of garbage sorting equipment are very considerable.
