Garbage incinerator body provided with four times of wind

Abstract

The invention provides a garbage incinerator body provided with four times of wind and belongs to the technical field of garbage incineration equipment. The garbage incinerator body solves the problems that an existing garbage incinerator body provided with a second-time wind inlet is uneven in wind distribution, high in requirement for power of a second-time fan, and large in energy consumption.A plurality of first-time wind inlets are formed in the bottom of an incinerator main body. A plurality of second-time wind inlets are formed in the lower portion of the outer wall of an incinerator.A plurality of radial ventilating holes are formed in the lower portion of the inner wall of the incinerator in the peripheral direction. A plurality of third-time wind inlets are formed in the middleportion of the incinerator main body above the combustion layer in the periphery direction. A plurality of four-time wind inlets are formed in the upper portion of the incinerator main body in the periphery direction. A plurality of first-time wind inlets communicate with a plurality of first-time fans in a one-to-one corresponding manner through pipelines. A plurality of second-time wind inletscommunicate with a plurality of second-time fans in a one-to-one corresponding manner through pipelines. A plurality of third-time wind inlets communicate with a plurality of third-time fans in a one-to-one corresponding manner through pipelines. A plurality of four-time wind inlets communicate with a plurality of four-time fans in a one-to-one corresponding manner through pipelines.

Description

technical field [0001] The invention relates to a furnace body of a garbage incinerator with quaternary air, belonging to the technical field of garbage incineration equipment. Background technique [0002] Most of the garbage incinerators in the prior art only have two air intakes, one at the bottom and one at the middle, which has the problems of uneven air distribution and uneven oxygen supply for incineration. The invention patent with application number 201220398753.9 discloses a The furnace body of the garbage incinerator with a secondary air inlet can increase the temperature of the combustion section of the furnace by setting a secondary air inlet on the metal outer wall of the lower furnace body, and by setting a tangential air inlet on the upper furnace body above the combustion section. The garbage can be further fully burned, but the air hole of the tangential air is connected with the air chamber of the secondary air by means of a pipe. Because the temperature i...

[0002] Most of the garbage incinerators in the prior art only have two air intakes, one at the bottom and one at the middle, which has the problems of uneven air distribution and uneven oxygen supply for incineration. The invention patent with application number 201220398753.9 discloses a The furnace body of the garbage incinerator with a secondary air inlet can increase the temperature of the combustion section of the furnace by setting a secondary air inlet on the metal outer wall of the lower furnace body, and by setting a tangential air inlet on the upper furnace body above the combustion section. The garbage can be further fully burned, but the air hole of the tangential air is connected with the air chamber of the secondary air by means of a pipe. Because the temperature in the furnace is relatively high, the tangential air formed by drawing air from the bottom to the top in this way is easy to burn. Insufficient flow and insufficient oxygen supply appear, and the air pressure in the furnace from bottom to top increases continuously, and the power requirement for the secondary fan is also greater, resulting in unnecessary energy consumption
