Problems solved by technology

In the prior art, activated carbon is used to absorb exhaust gas, but the utilization rate of activated carbon is actually not high. In many cases, only partial activated carbon is used, and it is reused. After replacing the exhaust gas treatment device, it is often found that There are still some activated carbons that are not fully utilized

specific Embodiment approach

[0033] A purification device for an automobile exhaust processor, comprising a filter cartridge 1, the filter cartridge 1 comprising a plurality of spliced ​​pipes 2 spliced ​​with each other, a plurality of spliced ​​pipes 2 are provided with sealing plates 3, and the sealing plates 3 are provided with There is a through hole 4, and the through hole 4 of the sealing plate 3 on the other splicing pipe 2 is misplaced. The through hole 4 is provided with a filter element, and the filter element is made of coal-based activated carbon, coconut shell activated carbon, modified At least one kind of activated carbon is a filter plate 6 made of raw materials. The tail gas enters from the air inlet and is discharged from the air outlet after passing through the filter plates 6 on several sealing plates 3. One end of the splicing pipe 2 is provided with a plug 7 , the inner wall at the other end is provided with a slide rail 8 for inserting the insert block 7 to rotate, the slide rail 8 ...

Embodiment approach

[0034] As an improved specific embodiment: several baffles 15 are arranged on both sides of the sealing plate 3 relative to the opening direction of the through hole 4, and the baffles 15 on the same side are spliced ​​end-to-end with each other to form a filter plate for fixing 6, the two ends of the filter plate 6 respectively extend out of the insertion groove 16.

[0035] As an improved specific embodiment: the positioning bar 13 passes through all the positioning holes 12 and then bends back toward the filter cartridge 1. After bending, the two ends overlap, one end of which is provided with a number of clamping holes 17, and the other end is provided with There is a clamping piece 18 embedded in the clamping hole 17 .

[0036] As an improved specific embodiment: the splicing pipe 2 is provided with an annular groove 19 , and the sealing ring 14 is embedded in the annular groove 19 . The through-holes 4 are fan-shaped and arranged in the circumferential direction with th...

Embodiment 1

[0051] Embodiment 1, in the selection of filter plate material, coal-based activated carbon is selected.

Abstract

The invention discloses a purification device of automobile tail gas treatment equipment. The purification device comprises a filter drum, wherein the filter drum comprises a plurality of splicing pipes which are spliced with one another; cover panels are arranged in the multiple splicing pipes; through slots are formed in the cover panels, and are staggered from the through slot of the cover panel on the other splicing pipe; filter elements are arranged in the through slots; tail gas enters the purification device from one end of the filter drum and then is discharged from the other end of the filter drum after passing through filter plates on the multiple cover panels; plug blocks are arranged at one-ends of the splicing pipes, and sliding rails capable of rotating after the plug blocks are plugged are arranged on the inner walls of the other ends of the splicing pipes; gaps for letting the plug blocks enter the sliding rails are formed in the sliding rails; stopper blocks for limiting excessive rotation of the plug blocks are arranged in the sliding rails; positioning lugs are further arranged on the splicing pipes; positioning holes are formed in the positioning lugs, and are communicated with one another after mounting is completed; and positioning strips penetrating through the positioning holes are arranged in an outer drum. Therefore, effects of convenience in mounting and improvement of the utilization rate of active carbon are achieved.

Description

technical field [0001] The invention relates to the technical field of exhaust gas treatment, in particular to a purification device for an automobile exhaust processor. Background technique [0002] Due to the low fuel consumption rate brought by high thermal efficiency, the diesel engine has good economy and reliability, which determines that the diesel engine will continue to be the mainstream engine in the engine design process and be widely used. However, the exhaust pollution of diesel engines has caused people to pay more and more attention to the environment, especially the soot particles and higher NOx emissions produced by diesel engines. Compared with a gasoline engine with the same power, due to the formation and combustion characteristics of the diesel engine mixture, its particulate (PM) emission is 30 to 50 times that of a gasoline engine. Therefore, it is of great significance to control the particulates in the exhaust emission of a diesel engine. [0003] P...
