Combustion treatment and comprehensive utilization production technology of household garbage

Abstract

The invention discloses a combustion treatment and comprehensive utilization production technology of household garbage. The combustion treatment and comprehensive utilization production technology specifically comprises the following steps: (1) carrying out primary crushing on mixed garbage: carrying out the primary crushing on household garbage materials in a sealed crushing device; (2) sieving:removing mud and percolated liquid from the materials through a sealed sieving device and recycling and treating the mud and the percolated liquid; (3) storing the materials: conveying the materialsinto a sealed storage bin through a sealed channel and recycling the percolated liquid and waste gas; (4) removing iron: uniformly conveying the materials in the sealed storage bin into an iron removing device; when the materials reach a magnetism-breaking position, an iron block falls into an appointed storage cabin; conveying other mixed garbage materials to the next section through a sealed conveyor; (5) carrying out treatment steps of washing mixed garbage with water and classifying, squeezing and dehydrating, drying, carrying out air separation, treating block-shaped materials and the like in sequence, and finally treating the garbage by classes. By adopting the technology, the stability and service life of a boiler can be improved and dioxin toxic gas is eliminated; the utilization and yield of biogas clean energy sources are improved.

Description

technical field [0001] The invention belongs to the technical field of waste incineration treatment methods, and in particular relates to a comprehensive utilization production process for domestic waste incineration treatment. Background technique [0002] With the improvement of living standards in urban and rural areas of our country, the output of domestic waste is increasing day by day, which has caused a burden to the beautiful living environment. The government attaches great importance to the disposal of domestic waste. The disposal methods are generally landfill and incineration to generate electricity. However, the landfill process is not ideal and the air pollution is serious, and the health of the staff on the site is not guaranteed. my country's domestic waste sanitary landfill technology began in the late 1980s. The Ministry of Construction promulgated my country's first sanitary landfill technical standard "Technical Specifications for Domestic Waste Sanitary ...

AI Technical Summary

Problems solved by technology

The mixed waste incineration process consumes a lot of energy, combustibles are not fully burned, and the dioxin index is high. The construction waste (non-combustibles) in the mixed waste plays a very bad and unsatisfactory role in the furnace, which greatly reduces the service life of the boiler. reduce

High maintenance costs, high energy consumption, etc., these are the sources of profit that plague waste-to-energy enterprises
