Problems solved by technology

[0008] The purpose of the present invention is to invent a new type of dry-process cement rotary kiln incineration method for domestic waste in view of the technical problems existing in the existing waste treatment methods and equipment. Garbage shredders, evenly rotating air-lock feeders, garbage container equipment, and a closed garbage screening workshop are designed to improve the quality and effect of garbage sorting, assembly, and crushing, and solve the impact of garbage feeding on the incinerator temperature , Garbage accumulation leads to technical problems of incomplete combustion

Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] Garbage is poured into the storage pool from the garbage container 1, grabbed onto the conveyor belt by the driving grab 2, and is processed by the bag breaking machine 3. Garbage passes through the roller sieve 4, and bulky garbage is sieved out, and is transported to the cutting platform 5 for cutting. The remaining small pieces of garbage are conveyed by the conveyor belt, and are sprayed with deodorant by the deodorizing sprayer 6 and enter the trommel 7 for screening. The non-combustible garbage is screened out and transported by the conveyor belt into the garbage container 1 for transportation to The designated platform is used as cement raw material processing. The combustible garbage is sprayed with a deodorant by a deodorizing sprayer 6, and the metals therein are selected by a magnetic separator 8 for recycling. The combustible garbage sieved by th...

Abstract

The invention discloses a rotary cement kiln burning method as a novel dry method of household garbage, which adopts a uniform garbage crusher, a uniform rotary wind-locking feeding machine and garbage container equipment to design a closed garbage sieving workshop. The invention improves the quality effect of garbage classification, packaging, crushing and feed processing, and solves the technical problems of influence on the furnace temperature of a combustion furnace during garbage feeding and insufficient burning caused by garbage accumulation. Clinkers of non-combustible garbage and combustible garbage are used as mixed materials of cement raw materials, and therefore, household garbage is totally treated reasonably. The whole treatment process has zero release and no harmful material, does not cause secondary pollution, and realizes the resourceful and harmless treatment of household garbage.

Description

Technical field: [0001] The invention belongs to the technical field of garbage treatment, and relates to a domestic garbage treatment method, in particular to a new dry-process cement rotary kiln incineration method for domestic garbage. Background technique: [0002] At present, there are more than 600 cities in our country, and the annual domestic waste has reached 150 million tons, and it is increasing at a rate of 8%-10%. In the municipal solid waste treatment technology, there are three methods widely used: sanitary landfill, incineration and composting. Due to capital and technical problems in small and medium-sized cities and towns in my country, 83% of domestic waste is disposed of by traditional sanitary landfill, 13% of domestic waste is disposed of by incineration, and another 4% is disposed of by composting. In the waste disposal in developed countries, more than 80% adopt industrialized treatment technology. The incineration treatment of domestic waste has th...
