Primary air intake pipe of garbage incineration furnace

Abstract

An intake pipe of a traditional garbage incineration furnace is only connected to the side wall of an ash funnel without extending into an internal cavity, so that the fullness of combustion assistant air in a primary air chamber is influenced, the combustion assistant air cannot uniformly pass through an air chamber to enter a garbage combustion material layer on a fire grate, garbage on the fire grate directly drops into slag discharge equipment when being not totally burnt, and the service life of the fire grate is shortened. In order to overcome the defects in the prior art, the invention provides a primary air intake pipe of a garbage incineration furnace; the device comprises an ash funnel and an intake pipe; the intake pipe extends into the ash funnel in the horizontal direction; a ventilation hole is formed in a pipe body of the lower half side of the intake pipe in the horizontal direction; and primary air passes through the intake pipe to feed in the ash funnel from the ventilation hole. As the fullness of the combustion assistant air in the primary air chamber is prominently improved, combustion flame is uniformly distributed on the surface of the fire grate, the service life of the fire grate is prolonged, and the garbage burnout rate is increased.

Description

technical field [0001] The invention relates to an air inlet device for a garbage incinerator, in particular to a primary air inlet duct for a garbage incinerator. Background technique [0002] The incineration grate is the core of the waste incineration device, and its function is to serve as supporting and conveying equipment in the process of burning waste. The garbage is pushed into the incinerator, and under the action of the preheated primary wind, the water in the garbage evaporates rapidly, and the garbage continues to absorb heat and heat up until the combustible matter reacts violently with oxygen. As the secondary air is sent in, the garbage is incinerated on the grate to produce volatilization and decomposition and continue to burn. The ash generated after the incineration of the garbage falls into the slag discharge equipment through the ash discharge port at the end of the grate. [0003] The incineration of garbage on the grate is a compound process, includin...

AI Technical Summary

Problems solved by technology

[0005] The existing air inlet pipe is only connected to the side wall of the ash funnel and does not extend into the inner chamber, which affects the fullness of the combustion air in the primary air chamber, causing the combustion air to not evenly pass through the air chamber into the garbage combustion material layer on the grate , that is, the flame is unevenly distributed on the surface of the grate, causing the unburned garbage on the grate to fall directly into the slagging equipment, reducing the service life of the grate
