Tail gas purification device with multi-channel structure

Abstract

The invention discloses a tail gas purification device with a multi-channel structure. The tail gas purification device comprises gas outlet pipes and filter layers, wherein a fixing rod is fixed on one sides of the gas outlet pipes; a first connecting groove is formed in one side of the fixing rod; an extrusion groove is formed in one side of the first connecting groove; extrusion blocks are embedded inside the extrusion groove; and a spring is connected between the extrusion blocks. According to the tail gas purification device with the multi-channel structure, a fixing groove is arranged and can be in butt joint with the fixing rod by pulling a filter frame, and thus the filter frame can be pushed to make the fixing groove slide with the fixing rod when the fixing groove is in butt joint with the fixing rod; after the fixing groove slides to one end of the fixing rod, a pressing rod can be pressed to slide with a moving groove; the inclined surface on one side of a clamping block can be extruded when the pressing rod slides; when the clamping block is extruded, the extrusion blocks can be pulled to move so as to stretch the spring; and the clamping block can be inserted into a clamping groove when being extruded, so that the gas outlet pipes and the filter frame are favorably assembled quickly.

Description

technical field [0001] The invention relates to the technical field of purifiers, in particular to a multi-channel exhaust gas purification device. Background technique [0002] Internal combustion engines use gasoline, diesel, LPG or CNG as fuel. The main harmful substances discharged are HC, CO, NOx and particulate matter (black smoke). The general structure of the exhaust gas purifier is a metal honeycomb carrier coated with a noble metal catalyst. The working principle is that when the high-temperature exhaust gas passes through the purifier, HC, CO and particulate matter react with oxygen under the action of catalyst and high temperature to become non-toxic water and carbon dioxide. [0003] At present, there are many defects in the multi-channel structure exhaust gas purification device on the market. It is inconvenient to assemble and replace the filter layer. Therefore, the technology that can improve the structure of the multi-channel structure exhaust gas purific...
