Tee joint for waste gas treatment air duct system and preparation method of tee joint

Abstract

The invention provides a tee joint for a waste gas treatment air duct system and a preparation method of the tee joint. The tee joint is composed of a main pipe and a branch pipe, the main pipe is detachably connected with the branch pipe in a detachable manner, so that the situation that the entire replacement is needed when any part of the main pipe and any part of the branch pipe is broken is avoided, and the use and maintenance cost is greatly reduced; a connecting boss, a connecting ring groove and a connecting convex ring are coordinated for use, so that the sealing performance is improved, and the leakage of waste gas is reduced; a heat conduction pipe is detachably connected to the main pipe so that the heat of the waste gas can be guided out, and the sealing performance and the connecting strength of the connection part between the branch pipe and the main pipe can be further protected; and an anti-corrosion inner layer can prevent the gas from corroding the tee joint, the wear resistance of an outer surface layer of the tee joint is improved through a wear-resistant protective outer layer, and the service life of the tee joint is prolonged.

Description

technical field [0001] The invention relates to the technical field of exhaust gas treatment air duct system accessories, in particular to a tee used for exhaust gas treatment air duct system and a preparation method thereof. Background technique [0002] The pipe joint with three openings is a three-way pipe. The three-way pipe is a kind of pipe connector, which is widely used in the pipeline network for conveying liquid and gas. It is used at the branch pipe of the main pipeline to change the direction of the fluid. Due to the different conveying media, the materials used are mainly divided into cast iron, cast steel, cast copper, cast aluminum, plastic and glass. [0003] Tee pipes are often used in exhaust gas treatment air duct systems. There are still many problems with the tee pipes used in exhaust gas treatment air duct systems in the prior art: the existing three-way pipes are simple in structure and generally adopt integrated Forming, when one of the branch pipes ...

Problems solved by technology

[0003] Tee pipes are often used in exhaust gas treatment air duct systems. There are still many problems with the tee pipes used in exhaust gas treatment air duct systems in the prior art: the existing three-way pipes are simple in structure and generally adopt integrated If there is a fault in the branch pipe or the main pipe, the whole tee needs to be replaced, which will increase the cost of maintenance, replacement and use; moreover, the main pipe and the branch pipe are vertically arranged, resulting in unbalanced air volume distribution and large pressure loss
