Description

Technical Field

[0001] The utility model relates to the technical field of automobile exhaust purification, in particular to a purifier for automobile exhaust. Background Art

[0002] With the development of society and the improvement of people's quality of life, cars are gradually entering every household. However, the rapid increase in the number of vehicles has also led to an increase in automobile exhaust emissions. Automobile exhaust is the waste gas produced when cars are used. It contains hundreds of different compounds, including pollutants such as solid suspended particulate matter, carbon monoxide, carbon dioxide, hydrocarbons, nitrogen oxides, lead and sulfur oxides. Exhaust directly harms human health and makes the problem of air pollution more and more serious. Therefore, the purification and treatment of automobile exhaust is particularly important.

[0003] Existing methods for purifying automobile exhaust gases mostly involve adding an exhaust purifier to the exhaust pipe of the automobile. However, most exhaust purifiers are directly fixed to the exhaust pipe. In particular, the exhaust purifier filters the exhaust gas through the filter element inside it. As the use time increases, the filtering effect of the filter element inside it also decreases. However, the exhaust purifier is not easy to disassemble and quickly replace the filter element inside it, resulting in certain limitations in the use of the device. In summary, existing automobile exhaust purifiers still have the following problems:

[0004] The exhaust gas purifier is difficult to disassemble, which makes the replacement efficiency of its internal filter relatively low, resulting in certain limitations in the use of the device. Utility Model Content

[0005] The main purpose of the utility model is to provide a purifier for automobile exhaust, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A purifier for automobile exhaust gas includes an air intake pipe, a mounting device fixedly mounted on the outer surface of the air intake pipe, a mounting shell fixedly mounted on the right end of the air intake pipe, a mounting inner shell mounted on the right end of the mounting outer shell, and an exhaust pipe fixedly mounted on the right end of the mounting inner shell.

[0008] Preferably, a honeycomb carrier is installed in the installation inner shell, an external thread is engraved on the outer surface of the installation inner shell, a high-temperature resistant sealing ring is installed on the right part of the outer surface of the installation inner shell, a fixing seat is installed on the right part of the front end and the right part of the rear end of the installation inner shell, a rotating handle is installed on the opposite ends of the two fixing seats, and a fixing screw is installed on the right end of the two fixing seats. The installation inner shell is screwed into the installation outer shell through the external thread on it. After the installation inner shell is screwed in, the fixing screw on the fixing seat is just aligned with the screw hole on the installation outer shell. Then the fixing screw is screwed into the screw hole, thereby further limiting and fixing the installation inner shell to prevent the installation inner shell from being easily screwed out due to shaking.

[0009] Preferably, the inner wall of the mounting shell is engraved with internal threads, and screw holes are provided at the front and rear right ends of the mounting shell. The honeycomb carrier can be removed and replaced by loosening the two fixing screws and then unscrewing the mounting inner shell. In addition, both the mounting inner shell and the mounting outer shell are made of stainless steel, and the double shell configuration also improves the protection effect of the honeycomb carrier inside.

[0010] Preferably, the mounting device includes a fixing ring, a mounting ring mounted on the left end of the fixing ring, and a plurality of mounting screws mounted on the outer surface of the mounting ring. The fixing ring is fixedly mounted on the outer surface of the intake duct. The mounting ring is sleeved onto the vehicle exhaust pipe, and then the plurality of mounting screws on the mounting ring are screwed in, thereby securing the mounting ring and the entire device to the exhaust pipe.

[0011] Preferably, the fixing screw is consistent with the screw hole in size and is positioned correspondingly on the left and right.

[0012] Preferably, a plurality of the mounting screws are distributed in an annular array on the outer surface of the mounting ring.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. First, the mounting ring on the mounting device is connected to the exhaust pipe of the automobile, and then several mounting screws on the mounting ring are screwed in to fix the mounting ring and the device as a whole on the exhaust pipe. Then, the mounting inner shell is screwed into the mounting outer shell through the external thread on it. After the mounting inner shell is screwed in, the fixing screws on the fixing seat are just aligned with the screw holes on the mounting outer shell. Then, the fixing screws are screwed into the screw holes to further limit and fix the mounting inner shell, preventing the mounting inner shell from being easily screwed out due to shaking, thereby improving the stability of the device after installation.

[0015] 2. The honeycomb channels inside the honeycomb carrier installed in the inner shell are coated with a catalyst. The components of the catalyst include rare earth metals such as platinum, palladium and rhodium. When the exhaust gas from the car passes through the channel of the purifier, carbon monoxide and hydrocarbons will react with oxygen in the air under the action of the catalyst platinum and palladium to produce harmless water and carbon dioxide, while nitrogen oxides are reduced to harmless oxygen and nitrogen under the action of the catalyst rhodium, thereby purifying the exhaust gas. Moreover, when the honeycomb carrier needs to be cleaned and replaced, only two fixing screws need to be loosened, and then the inner shell can be unscrewed to disassemble and replace the honeycomb carrier. In addition, the inner shell and the outer shell are both made of stainless steel, and the double shell setting also improves the protection effect of the honeycomb carrier inside it.

[0028] It should be noted that the present invention is a purifier for automobile exhaust gas, which is sleeved on the automobile exhaust pipe through the mounting ring 41 on the mounting device 4, and then several mounting screws 42 on the mounting ring 41 are screwed in, so that the mounting ring 41 and the device as a whole are fixed on the exhaust pipe, and then the mounting inner shell 2 is screwed into the mounting outer shell 3 through the external thread 24 thereon. After the mounting inner shell 2 is screwed in, the fixing screws 21 on the fixing seat 20 are just aligned with the screw holes 31 on the mounting outer shell 3, and then the fixing screws 21 are screwed into the screw holes 31, thereby further limiting and fixing the mounting inner shell 2, preventing the mounting inner shell 2 from being easily shaken and screwed out, thereby improving the stability of the device after installation, and at the same time, the inner shell 2 is installed. The honeycomb-type channels inside the honeycomb carrier 25 are coated with a catalyst, and the components of the catalyst include rare earth metals such as platinum, palladium and rhodium. When the exhaust gas from the automobile passes through the channel of the purifier, carbon monoxide and hydrocarbons will react with oxygen in the air under the action of the catalysts platinum and palladium to produce harmless water and carbon dioxide, while nitrogen oxides are reduced to harmless oxygen and nitrogen under the action of the catalyst rhodium, thereby purifying the exhaust gas. Moreover, when the honeycomb carrier 25 needs to be cleaned and replaced, it is only necessary to loosen the two fixing screws 21, and then unscrew the mounting inner shell 2 to disassemble and replace the honeycomb carrier 25. In addition, the mounting inner shell 2 and the mounting outer shell 3 are both made of stainless steel, and the double shell setting also improves the protection effect of the honeycomb carrier 25 therein.
