Low-temperature pyrolysis gasification method and pyrolysis gasification device for domestic garbage

Abstract

The invention relates to a low-temperature pyrolysis gasification method for domestic garbage and a low-temperature pyrolysis gasification device for domestic garbage. The low-temperature pyrolysis gasification device for domestic garbage comprises a low-temperature pyrolysis gasification furnace (1), an air magnetization air supply device (2), and a water seal flame arrester (3), wherein the low-temperature pyrolysis gasification furnace (1) mainly comprises a furnace body (10), an air outlet pipe (12), a feed port (13), an annular partition plate (14), an oscillating fire grate (15), an ashcleaning port (17), a throat pipe (18), an ignition port (19), and an air inlet pipe (16). In the domestic garbage from which unburnable large bricks and stones are sorted out, the low-temperature pyrolysis gasification furnace (1) is used and the air volume input into the furnace is controlled by adjusting the air magnetization air supply device (2); the temperature of an oxidization zone of an inner cavity of the throat pipe (18) is controlled between 450 DEG C and 550 DEG C, and the low-temperature pyrolysis gasification of domestic garbage is performed at the air outlet temperature of theupper part of the furnace body of between 100 DEG C and 250 DEG C. The low-temperature pyrolysis gasification device for domestic garbage is particularly suitable for the treatment of domestic garbagein rural towns, hospitals and the like, the operation is simple and convenient and the pyrolysis gasification effect is good.

Description

technical field [0001] The invention relates to a low-temperature pyrolysis gasification method for domestic garbage and a low-temperature pyrolysis gasification device for domestic garbage. Background technique [0002] Domestic waste pyrolysis treatment methods are divided into incineration treatment methods and gasification treatment methods. It can reduce the garbage volume by 98% and reduce the weight by 95%. [0003] The domestic waste incineration treatment method is to use an incinerator to perform high-temperature pyrolysis and combustion treatment on the waste. The method is simple and the treatment speed is fast. However, due to the low calorific value and high water content of domestic waste, it is necessary to provide auxiliary fuel for combustion. The investment and operating costs of incineration treatment equipment are high, and there is a great hidden danger of environmental pollution in the direct incineration of garbage, and it is difficult for the flue ...
