Problems solved by technology

During the slag discharge process, the burning ash will generate a large amount of ash, which will cause a bad working environment and is not conducive to on-site operation.
Because the furnace temperature is too high, in order to prevent the garbage from being ignited during the feeding process, it is necessary to wait for the temperature in the furnace to drop when feeding again. Generally, the cooling time of the furnace is more than 5-6 hours, which affects the continuous operation.

Embodiment Construction

[0015] When feeding, the top cover 1 is lifted by the hydraulic device 2 and slides to one side through the guide rail 14. After the garbage is added to the furnace, the top cover 1 slides back to its original position and is tightly sealed with the furnace body 3. The furnace is composed of the top cover 1 and the furnace body 3. , hearth 4, grate device 5 components. The garbage is ignited through the ignition of the burner, and the supply of combustion-supporting air is controlled, so that the garbage is incompletely burned in the furnace to generate combustible smoke, which enters the secondary combustion chamber through the smoke outlet 8 to continue burning.

[0016] The top cover 1 and the furnace body 3 are composed of double-layer steel plates. Cooling water is added to the interlayer, and the water level is controlled by the expansion tank 9, and a certain steam space is reserved in the water-cooled wall, and part of the heat is taken away by water evaporation, which ...

Abstract

The present invention relates to one kind of primary combustor for garbage incinerator to pyrolyze dangerous waste through incomplete combustion to produce inflammable gas. The primary combustor consists of top cover, furnace body, hearth, grate unit and slag bin. The movable top cover covers the upper surface of the furnace body, cooling water is fed into the sandwich layer of the top cover and the furnace body to form water cooling wall structure with water level controlled with an expansion water tank and certain steam space reserved. The surfaces of the hearth and the grate have high pressure air nozzles arranged, and the grate in the bottom of the hearth is maintained immobile during burning and turned by 90 deg during draining slag. The grate unit has water spraying holes in the lower part.

Description

technical field [0001] The invention belongs to an incinerator, and in particular relates to a primary combustion chamber furnace body for incinerating medical and industrial hazardous wastes by means of pyrolysis. Background technique [0002] At present, the incineration treatment of hazardous solid waste has been paid more and more attention. The country has formulated many relevant regulations and standards, and the environmental protection requirements are becoming more and more stringent. According to relevant national regulations, waste incineration generally adopts pyrolysis, rotary, fluidization, etc., and pyrolysis furnaces are widely used due to their low construction costs and low operating costs. There are two types of pyrolysis furnaces: continuous feeding type and batch feeding type, both of which are composed of feeding device, furnace body, hearth and slag discharge device. At present, there are still some shortcomings that are difficult to overcome in the ...
