Problems solved by technology

[0002] The heating gas of the existing coal carbonization furnace is directly input into the furnace cavity through the gas pipeline and the air pipeline, so the distribution of the input gas in the raw coal is not uniform, so the uniform heating of the coal cannot be realized
It will have adverse effects on the quality and yield of coke and coal tar

Abstract

The invention relates to a branch mixer, wherein the inner tube is sheathed with outer tube to form dual-layer steel tube structure; one end of inner tube is the ejector, while one relative end of outer tube is ejector; another end near the outer tube has outer tube connector on the side wall; the outer tube connector is connected to the main gas tube connector. The invention has simple structure; the high-pressure air of inner tube is high-speed ejected from the inner tube ejector, to eject the gas in outer tube at high speed, to be mixed uniformly to be ejected into furnace, to uniformly distribute the heating gas in retort furnace.

Description

technical field [0001] The invention relates to a mixer, in particular to a branch tube mixer used in a low-temperature carbonization furnace for mixing heating gases and uniformly feeding them into the furnace. Background technique [0002] The heating gas of the existing coal carbonization furnace is directly input into the furnace cavity through the gas pipeline and the air pipeline, so the distribution of the input gas in the raw coal is not uniform, so the uniform heating of the coal cannot be realized. It will have adverse effects on the quality and yield of semi-coke and coal tar. Contents of the invention [0003] In order to solve the above-mentioned problems, the object of the present invention is to provide a branch pipe mixer for uniformly mixing the heating gas of the low-temperature carbonization furnace on the same level in the furnace and forming a high-speed air flow into the furnace. [0004] Technical scheme of the present invention is realized like thi...
