Garbage pyrolysis gasification furnace and method

Abstract

The invention discloses a garbage pyrolysis gasification furnace and a method. The garbage pyrolysis gasification furnace comprises a furnace body, a moving device arranged at the top of the furnace body and a discharging mechanism connected with the moving device, the moving device drives the discharging mechanism to reciprocate in the length direction of the feeding port of the furnace body, and the discharging mechanism communicates with the furnace body so that garbage in the discharging mechanism can enter the furnace body, the furnace body is used for pyrolyzing entering garbage, a rotary shifting mechanism is arranged in the furnace body, an ash bin is arranged on one side of the furnace body, a baffle component is arranged on the side face, close to the ash bin, of the furnace body, and the discharging mechanism, the moving device and the rotary shifting mechanism are all controlled by a monitoring module; the method comprises the following steps: step 1, reciprocating garbage blanking; and step 2, pyrolysis and gasification of the garbage. Garbage can enter the furnace body conveniently, so that the garbage in the furnace body is evenly distributed, the pyrolysis and gasification efficiency is improved, ash residues generated after garbage pyrolysis and gasification are prevented from blocking the furnace cavity, and long-term efficient and stable gasification operation of the garbage pyrolysis furnace is facilitated.

Description

technical field [0001] The invention belongs to the technical field of garbage pyrolysis and gasification furnaces, in particular to a garbage pyrolysis gasification furnace. Background technique [0002] Garbage pyrolysis and gasification is a process in which the macromolecules of the organic components in the garbage are broken to produce small molecule gases, tar and residues. Garbage pyrolysis gasification technology not only realizes the harmlessness, reduction and recycling of garbage, but also effectively overcomes the pollution caused by garbage incineration, so it has become a promising garbage treatment technology. However, there are still some problems in the current waste pyrolysis gasifier: [0003] First, when the garbage enters the furnace body through the silo, there is uneven distribution of garbage in the furnace body, and there is a small amount of garbage in the furnace body, and there is a short circuit of the air flow; there is a lot of garbage in the...

AI Technical Summary

Problems solved by technology

[0003]First, when the garbage enters the furnace body through the silo, there is uneven distribution of garbage in the furnace body, there is less garbage in the furnace body, and there is a short circuit of the air flow; There is a lot of garbage in the body, and there is a problem of insufficient pyrolysis and gasification;

[0004]Second, the ash generated after the waste pyrolysis and gasification in the furnace body is easy to block the furnace cavity, which is not convenient for the long-term efficient and stable operation of the waste pyrolysis furnace gasification
