Haiqi Waste Pyrolysis and Gasification
As people's environmental awareness is increasing day by day, governments around the world have raised the technical standards for waste disposal, and the defects of traditional main methods of waste disposal --- landfill, composting, incineration and other technologies have become increasingly prominent, such as waste landfills occupying a large area of land , The amount of composting is small, the efficiency is low, and the incineration is easy to produce secondary pollution, especially the pollution of dioxin, which hinders its development. Therefore, the development of adaptable, efficient and clean garbage disposal technology is the key to solving the problem of urban garbage, and it is also the trend of developing garbage disposal technology in all countries in the world. Waste pyrolysis technology can effectively overcome the problem of tail gas pollution caused by waste incineration while realizing the harmlessness, reduction and recycling of waste. Therefore, it has become an emerging waste treatment technology with great development prospects. It also makes the garbage pyrolysis gasification technology known as the third generation technology of garbage treatment.
Harmless, Resourceful, Reduced
Using gasification combustion to treat domestic waste can well achieve the purpose of harmless, resourceful and reduction of waste, and can achieve a win-win situation of environmental and economic benefits. First of all, through high-temperature gasification and combustion, the purpose of harmlessness and reduction is well achieved. The most intuitive performance is to save land resources. For the same amount of waste disposal, the land area required by waste incineration plants is much smaller than that of waste sanitary landfills. In addition, through the incineration of domestic waste to achieve energy conversion, energy can be reused, resulting in considerable economic benefits.

What social and economic benefits can be achieved by building a domestic waste treatment plant with a daily processing capacity of 300t/d and configuring two domestic waste gasification combustion lines with a daily processing capacity of 125t?
A. It can process 300 tons of domestic waste per day, and achieve the purpose of harmlessness, reduction and resource utilization through high-temperature gasification and combustion, and solve the domestic waste disposal problem in counties with a population of 400,000.
B. After the project is put into operation, it can provide 40-60 jobs for the local area.
C. Based on the investment of 200,000 yuan per ton of domestic waste incineration plant equipment, the construction of a 300t domestic waste plant can create an output value of 60 million yuan for the enterprise.
D. Considering the garbage disposal fee of 120 yuan/ton and 330 days of annual operation, the annual garbage disposal fee is 11.88 million yuan.
E. The calorific value of domestic waste entering the gasification combustion furnace is considered to be 1500Kcal/kg, which can generate about 18 tons of steam per hour, and a set of 3000kw generator set can be configured to generate electricity; it can provide heating for houses of about 150,000 m2; Heat users provide steam; steam can also be used to process hot water for hotels and hotels. Taking the direct sale of steam as an example, based on 100 yuan per ton of steam and 8,000 hours of annual operation, the annual steam income can reach 14.4 million yuan.
F. Garbage disposal fee is calculated at 120 yuan/ton, and the annual operating income of the main operation is about 26 million yuan. Electricity, labor, water, materials (industrial salt, Ca(OH)2, activated carbon, ignition wood, ignition The annual operating expenses such as diesel fuel consumption, environmental protection testing fees and office expenses are about 9 million yuan.
To sum up, we believe that in counties and cities with less than 300 tons of daily waste, the calorific value of medical waste is 5000Kcal/kg, the calorific value of domestic waste is 1200-1500Kcal/kg, and the diameter of 4500 can handle 40-60 tons of medical waste. 120-150 tons of domestic waste. It is feasible to use waste pyrolysis gasification combustion boiler to treat domestic waste.
