Abstract

The invention discloses a workshop waste gas catalytic purification mechanism. The mechanism comprises a gas inlet pipe, a gas inlet flow guide pipe, a barrel, a carrier, a gas outlet flow guide pipe and a gas outlet pipe. The gas inlet flow guide pipe and the gas outlet flow guide pipe are both in conical cylinder shaped structures, and the large-diameter end of each of the gas inlet flow guide pipe and the gas outlet flow guide pipe is connected with the barrel. The gas inlet pipe is connected with the small-diameter end of the gas inlet flow guide pipe, and the gas outlet pipe is connected with the small-diameter end of the gas outlet flow guide pipe. The carrier is arranged in the barrel, an insulating partition layer is arranged between the barrel and the carrier, and reinforcement rings are arranged on the inner wall of the barrel. The workshop waste gas catalytic purification mechanism has the advantages that gas is enabled to uniformly flow into the carrier to make full use of catalysts in the carrier.

Description

[0001] The invention relates to a catalytic converter, and more specifically, to a catalytic purification mechanism for exhaust gas in a workshop. Background technique [0002] At present, many workshops are equipped with exhaust gas catalytic converters, which are installed in the exhaust air passages, and convert the exhaust gas through redox reactions. For catalytic purification equipment with a conventional structure, the airflow is generally concentrated in the central area of ​​the carrier, while the airflow at the edge of the carrier is very small, which causes the airflow velocity and temperature to be high in the central area, causing the catalyst to age quickly in the central area. The marginal area is not fully utilized, which not only reduces the service life of the catalytic converter, but also reduces its conversion efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the problem in the prior art that the air flow i...
