Abstract
The utility model relates to a vehicle exhaust purifying and silencing apparatus, comprising a dust remover and a purifying and silencing apparatus. The inlet pipe and the exhaust pipe are positioned in the purifying and silencing apparatus in parallel; ventholes are arranged on the pipe wall, the outer surface of the pipe wall is wrapped with an activated carbon fiber layer, and the outer surface of the activated carbon fiber layer is tightly encircled with a silk screen layer; the inlet pipe is connected to automobile exhaust, and the rear end of the exhaust pipe is connected to the atmosphere. The utility model has advantages of high purifying efficiency, small size, and light weight and is suitable for various types of automobile.
Description
The utility model relates to the exhaust gas purification baffler that a kind of automobile is used.
In the prior art, a kind of testing apparatus that use carbon fiber remove nitrogen oxide of Japan's " Nikkei Business Daily " in the lucky river Ying Fu professor of report Chiba polytechnical university on October 17th, 1991 arranged, gas of combustion there is certain purifying effect, be suitable for use as automobile exhaust gas purifying device, but do not enter the practical stage.
The purpose of this utility model is: on above-mentioned prior art basis, provide a kind of practicality and more effective automobile exhaust gas purifying baffler.
For achieving the above object, the utility model adopts following technical proposals: this automobile exhaust gas purifying baffler is the same with prior art to be included the housing of a purification silencer and connects the suction tude of automobile exhaust and the outlet pipe of connection atmosphere.Be characterized in: extend on the section of enclosure interior in suction tude and outlet pipe, uniform vent, and on outer surface of tube wall, be wrapped in one deck acf layer, acf layer outer surface circle is speeded up one deck silk screen layer.During use, automobile exhaust enters suction tude, and the acf layer of flowing through of the vent from the air inlet tube wall enters in the housing chamber, and the acf layer on outlet pipe and enter outlet pipe by vent is discharged in the atmosphere at last then.Like this, automobile exhaust noise reduction of reducing pressure gradually by the vent on suction tude and the outlet pipe and acf layer purifies through acf layer simultaneously.Because the purifying effect of activated carbon fiber is better than the effect of carbon fiber, so this exhaust gas purification baffler far surpasses the lucky river Ying Fu professor's of Chiba, Japan polytechnical university testing apparatus to the purifying effect of automobile exhaust.
The suction tude of this exhaust gas purification baffler can directly be connected automobile exhaust.Also can connect automobile exhaust by a deduster, promptly at purification silencer housing front end a deduster is housed, the suction tude of purification silencer is communicated with deduster, and an air inlet connecting leg of connecting automobile exhaust is arranged on the deduster.Like this, automobile exhaust is earlier through deduster and gets rid of imperfect combustion formed carbon granules and impurity dust, and exhaust enters purification silencer then, prevents that carbon granules and impurity dust from stopping up activated carbon fiber, prolongs purification silencer working life.
Described deduster can be designed as: the cylindrical body of deduster housing for erectting, and the bottom is a taper, there is plug screw the taper lower end, spins off plug screw and can discharge the carbon ash that accumulates in the deduster bottom.There is fixing center tube at the cylindrical body center, and the suction tude of purification silencer is connected with the cylindrical body middle part and extends in the cylindrical body, and the air inlet connecting leg is communicated with cylindrical body top, preferably with tangential connection.Like this, automobile exhaust enters deduster and around the center tube rotational flow through the air inlet connecting leg from the cylindrical body upper tangential, makes carbon granules and dust throw barrel and sink by the centrifugal force of eddy flow, and exhaust enters the suction tude of purification silencer then.On the air inlet connecting leg fastening screw trip bolt is arranged, the outlet pipe socket that is used for air inlet connecting leg and automobile is fixed.
Purification silencer can be designed to: the housing of purification silencer is a cylindrical body, and its front end is fixedlyed connected with the deduster housing, and the fixedly connected bonnet in its rear end.The rear end of suction tude is fixedly connected on the bonnet, and front end is located by the positioning block that is fixed on the deduster housing.Outlet pipe passes bonnet, fixedlyed connected with bonnet by fixing swivel nut, and front end is located by the positioning block that is fixed on the deduster housing.Like this,, just can together suction tude and outlet pipe be extracted out in the purification silencer housing, clear up maintenance as long as pull down bonnet.
Because activated carbon fiber is high temperature resistant, is that carrier applies combustion catalyst so can adopt activated carbon fiber in acf layer of the present utility model, then the effect of this exhaust gas purification baffler is better.
The utility model has following obvious advantage compared with prior art: this exhaust gas purification baffler purification efficiency height, gas-flow resistance is little, thermostability is high, volume is little and in light weight.
The drawing of accompanying drawing is described as follows:
Fig. 1 is structural representation of the present utility model (Fig. 1 is B-B place sectional view among Fig. 2).
Fig. 2 is an A-A place sectional view among Fig. 1.
Label representative in the accompanying drawing: 1-is swivel nut fixedly, 2-bonnet, 3-vent, the 4-purification silencer, 5-outlet pipe, 6-acf layer, the 7-silk screen layer, the housing of 8-purification silencer, 9-positioning block, the 10-deduster, 11-center tube, 12-air inlet connecting leg, the 13-fastening screw trip bolt, the housing of 14-deduster, 15-plug screw, the 16-suction tude, the 17-positioning block.
An optimum implementation of the present utility model is: referring to Fig. 1 and Fig. 2, this automobile exhaust gas purifying baffler comprises two parts: deduster 10 and purification silencer 4.The cylindrical body of deduster 10 housings 14 for erectting, the bottom is a taper, there is plug screw 15 the taper lower end.There is fixing center tube 11 at the cylindrical body center.Cylindrical body top circumference tangentially connects air inlet connecting leg 12, and fastening screw trip bolt 13 is arranged on the air inlet connecting leg 12.The housing 8 of purification silencer 4 is the cylindrical body of substantially horizontal, and front end and 14 welding of deduster 10 housings are linked to be an integral body, the fixedly connected bonnet 2 in rear end.The suction tude 16 of a purification silencer is placed in the purification silencer housing 8, fixedly connected with bonnet 2 in its rear end, and front end is by positioning block 17 location that is fixed on the deduster housing 14, and the front end of suction tude 16 extends in the deduster housing 14 after passing the center hole of positioning block 17.The outlet pipe 5 of a purification silencer is arranged in parallel with suction tude 16, and its rear end is passed bonnet 2 and stretched out, and the end is bent downwardly, and by fixing swivel nut 1 outlet pipe 5 is fixedlyed connected with bonnet 2.The front end of outlet pipe 5 is located by the positioning block 9 that is fixed on the deduster housing 14.Suction tude 16 and outlet pipe 5 extend in uniform vent 3 on the section of purification silencer housing 8 inside, and are wrapped in one deck acf layer 6 at outer surface of tube wall, and acf layer 6 outer surface circles are speeded up layer of metal silk screen layer 7.
