Suspension combustion carbonization cracking integrated equipment

Abstract

The invention discloses suspension type combustion, carbonization and splitting integrated equipment. The integrated equipment comprises a double-layer splitting furnace with a sandwich layer, and a combustion furnace mounted on the splitting furnace; a garbage distributor for suspending organic solid wastes and a rotating screw rod for uniformly distributing garbage are arranged in the splitting furnace; the combustion furnace is divided into a primary combustion chamber and a secondary combustion chamber by a cyclone plate; the cyclone plate largely prolongs the stop time of splitting gas in the combustion furnace, so that the splitting gas is fully burnt; and burnt tail gas enters the sandwich layer of the splitting furnace by an afterheat recovery pipe for heating an inner furnace body of the splitting furnace to bake the organic solid wastes therein. The integrated equipment is simple in structure, low in equipment investment and full in garbage splitting and combustion, and radically prevents the generation of such harmful gas as dioxin.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a suspended combustion, carbonization and cracking integrated equipment. Background technique [0002] As waste volumes continue to grow, so does the pressure to dispose of them. The hazards of municipal solid waste are not only manifested in occupying too much land, forming a harsh environment surrounded by garbage in the city, but also polluting the atmospheric environment, groundwater sources, soil and crops. [0003] There are two main ways to deal with domestic waste: one is landfill, which not only takes up a lot of land, but also causes damage to soil and groundwater if seepage is produced; the other is incineration. Domestic waste incineration treatment is a relatively common waste treatment technology at present, which can fully recover the heat energy in the waste, which is the embodiment of waste reduction. The traditional garbage treatment furnace directly bu...

AI Technical Summary

Problems solved by technology

The traditional garbage treatment furnace directly burns the garbage. However, the garbage contains a lot of water. Direct combustion in the state of low calorific value of the garbage will make the garbage incomplete and produce a large amount of dioxin. To increase the calorific value It is necessary to add auxiliary fuels such as coal, oil, and electricity to increase the temperature, which increases the cost and causes further waste of energy.

Traditional waste heat recovery devices often use air-water heat exchangers to heat water for other uses. However, since garbage dumps are usually built far away from residential areas and factory areas, hot water is transported through long-distance pipelines and its calorific value is lost. Large, such methods are not practical

Moreover, in order to ensure the residence time of the flue gas so that the flue gas can be fully burned, the traditional combustion furnace often uses complex and bulky flues, which makes the equipment occupy a large area and is difficult to maintain, but the actual use efficiency is not satisfactory.
