Problems solved by technology

The problem of using landfill is that it needs to occupy a large amount of land, and there is a long decomposition period, and the leakage of sewage will cause serious harm to the soil and groundwater around the landfill.
The problem with high-temperature incineration treatment is that the required equipment investment and operating costs are very high, and a sufficient amount of waste sources are needed to maintain operations, which is not suitable for township use
The low-temperature pyrolysis treatment belongs to anoxic incineration technology, which has the advantages of less investment in equipment and low operating costs. It is especially suitable for the situation where the amount of garbage in towns and villages is small and unstable. However, due to technical reasons, the garbage is carbonized and pyrolyzed in the pyrolysis furnace. Slow speed, uneven pyrolysis, especially when there is a lot of garbage and high humidity after holidays, it is prone to problems such as extinguishing and burning

Abstract

The invention discloses a low-temperature thermal decomposition furnace for garbage. The low-temperature thermal decomposition furnace comprises a furnace body, a feeding port, and a grate. The upper part of the furnace body is provided with the feeding port. The lower part of the furnace body is provided with the grate. An ash bucket is arranged below the grate. The lower part of the furnace body is provided with multiple air inlets communicating with the grate. An oxygen uniformly-distributing and auxiliary combustion device is arranged above the grate and communicates with the air inlet pipe stretching outwards. The bottom of the furnace body is provided with an electric ash-discharging device connected with the ash bucket. The low-temperature thermal decomposition furnace for garbage has following beneficial effects: air inlet volume can be adjusted so that the highest temperature in a roof of the furnace is kept at 860 DEG C, thereby lessening or avoiding generation of dioxin; garbage can be uniformly decomposed and processed; and long term operation can be maintained without addition of auxiliary material.

Description

technical field [0001] The invention relates to the technical field of garbage treatment equipment, in particular to a low-temperature pyrolysis furnace for garbage. Background technique [0002] At present, the domestic waste of urban residents is generally disposed of by landfill, high-temperature incineration, and low-temperature pyrolysis. The problem of using landfill is that it needs to occupy a large amount of land, and there is a long decomposition period, and the leakage of sewage will cause serious harm to the soil and groundwater around the landfill. The problem with the high-temperature incineration treatment method is that the required equipment investment and operating costs are very high, and a sufficient amount of waste sources are required to maintain operations, which is not suitable for township use. The low-temperature pyrolysis treatment belongs to anoxic incineration technology, which has the advantages of less investment in equipment and low operating...
