Secondary air inlet type garbage incinerator

Abstract

The invention discloses a secondary air inlet type garbage incinerator. The garbage incinerator comprises an incinerator body and a combustion chamber, the combustion chamber comprises a one-time combustion chamber body and a secondary combustion chamber body; the one-time combustion chamber body is arranged on the lower portion of the whole incinerator body, a fire bar is arranged in the center of the lower cone base of the one-time combustion chamber body, and an inspection port extends out of the incinerator body from the edge of the end parallel to the back of the fire bar; a secondary airinlet passage and a material inlet are parallelly formed in the middle of the whole incinerator body; an air inlet of the secondary air inlet passage is formed in one side of the secondary air inletpassage; air inlet ports used for conveying the air to the inside of the air passage are respectively formed in a lower cone plate and an inner vertical plate of the secondary air inlet passage; the secondary combustion chamber body is arranged on the upper portion of the whole incinerator body; a flue passage of the secondary combustion chamber body is arranged on the top of the secondary combustion chamber body and surrounds the periphery of a whole inner circle; a flue gas outlet of the secondary combustion chamber body is formed in a vertical panel of the inner cycle; a flue gas outlet pipe is communicated with the flue passage of the secondary combustion chamber body and extends out of the incinerator body. The invention provides the household waste incinerator which does not need auxiliary fuel and can make flue gas achieve the secondary combustion. The quantity of generated flue gas is reduced, the pollutant discharging is reduced, and the harmless incineration treatment for household waste is achieved.

Description

technical field [0001] The invention belongs to the technical field of domestic garbage treatment equipment, and the invention relates to a garbage incinerator used as a supporting unit in a harmless incineration treatment device for domestic garbage. Background technique [0002] The patent literature of Chinese Patent No. 02273965·3 discloses a patented technology of "a garbage incinerator capable of utilizing output heat energy", the main scheme of which is: in the furnace of the main body of the incinerator, including a flame isolation at the feeding port The board is connected to the inner cavity of the furnace through hinges, and there are special air branch pipes. No nozzles are distributed at the front ends of each branch pipe. The blower is used to blow the external air, that is, the forced convection method, and the blower is used to blow air into the branch pipes and The nozzle blows air into the furnace cavity. In the upper part of the inner cavity of the furnac...

Problems solved by technology

For the comprehensive analysis of the above two patented technologies, in addition to the above defects, the establishment of the relationship between mass conservation, such as the mass ratio of the generated smoke density state and temperature, etc., reflects the physical authenticity and overall balance. There are also defects, and there are defects in the secondary combustion of the flue gas to reduce the generation of harmful substances in the cavity. Generally speaking, it is still not perfect.
