Pyrolysis gasification equipment for treating garbage

Abstract

The invention discloses pyrolysis gasification equipment for garbage disposal, and the equipment comprises a pyrolysis gasifier which is provided with a grate at the lower part and at least one gas outlet at the upper part; a spiral feeding device which is used for conveying materials to the pyrolysis gasifier; a feeding hopper which is arranged above the spiral feeding device; a blower system anda fuel injection system which is used for injecting a fuel into the pyrolysis gasifier; the fuel injection system includes: a fuel nozzle for injecting a mixed gas to a grate region; a first fan; a first valve and a second valve; a branch pipe; a third valve and a fuel source; the air inlet end of the first fan is connected with an air outlet through an air inlet pipe, and the air outlet end is connected with the fuel nozzle through an air outlet pipe; the first valve and the second valve are mounted on the air inlet pipe; the branch pipe is connected with the air inlet pipe; the third valveis mounted on the branch pipe; and the fuel source is connected with the air inlet pipe or the air outlet pipe. The fuel passes through the first fan, the fuel and a generated combustible gas are sprayed into a cracking furnace through the nozzle to be combusted, a large amount of heat is generated to be used in the cracking gasification process, and the pyrolysis gasification equipment can be better suitable for garbage with the high water content.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to cracking and gasification equipment for disposing of garbage. Background technique [0002] In the prior art, the garbage is processed through the pyrolysis gasifier. During the garbage disposal process, only the mechanically sorted materials enter the cracking gasifier. The moisture content of the garbage is relatively high. The traditional cracking gasifier is not suitable for this Garbage with high humidity cannot be processed well. Contents of the invention [0003] Aiming at the above problems, the present invention proposes a cracking gasification device for disposing of garbage. [0004] The technical scheme that the present invention takes is as follows: [0005] A pyrolysis gasification device for disposing of garbage, comprising: [0006] A cracking gasifier, used for cracking and gasifying materials to form solid slag and gaseous combustible gas. The lower part of...
