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

Embodiment Construction

[0023] In order to further illustrate the present invention, further illustrate below in conjunction with embodiment:

[0024] Odor gas recovery, back to the furnace to support combustion and play a role in purification, sealed silo, negative pressure production process waste is not exposed, improve the odor generated in the production process of the workshop, and extract odor gas from the source of the sealed storage silo with negative pressure, sorting There is a device for recovering odor gas at each inlet and outlet sealing connection of the equipment. The fan will extract and concentrate the odor gas to the main pipe of the boiler air inlet. The odor gas is also responsible for sending the dried combustibles into the boiler. The combustion process of the boiler A large amount of air is needed to support combustion, and the odor generated by the sealed silo and the complete set of equipment in the production process is recycled and utilized, which conforms to the boiler pro...

Abstract

The invention discloses an incineration disposal and comprehensive utilization production technology for household rubbish. The incineration disposal and comprehensive utilization production technology for the household rubbish is characterized in that after solid-liquid separation is conducted on the household rubbish in a sealed environment, combustible materials are burnt, and exhaust gas and liquid are recycled. By the adoption of the technology, the coal burning amount can be reduced, recycled plastics can be extracted, the environment of a dump pit is improved, the factory and workshop environment is improved, the environment of the inside of a boiler is also improved, the service life of the boiler is prolonged, and the dioxin gas index is lowered.

Description

technical field [0001] The invention relates to a production process for comprehensive utilization of 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 Landfill" (cjj17-88). It has officially entered the stage of sanitary landfill characte...
