Automobile tail gas processing device

Abstract

The invention discloses an automobile tail gas treatment device, which comprises a shell, an intake pipe, a superfine fiber cloth, a clean air cavity, a tubular inorganic ceramic membrane, a non-woven fabric, a nanofiber membrane, an exhaust pipe, a pillar and the like. The air inlet pipe is connected with the clean air chamber, and all the exhaust gas enters the clean air chamber. The microfiber cloth is located at the front end of the clean air chamber inlet and has double layers, which are used to filter larger particles in the exhaust gas. The tubular inorganic ceramic membrane is embedded in the clean air chamber, which is seamlessly connected. The tubular inorganic ceramic membrane can remove most of the harmful substances in the exhaust gas. The non-woven fabric and nanofiber membrane are between the clean air chamber and the inner wall of the shell. Among them, the nanofiber membrane is embedded in the non-woven fabric, and the activated carbon contained on the nanofiber membrane can absorb harmful substances that are not removed by the tubular inorganic ceramic membrane. The invention is a kind of automobile tail gas processing equipment which fully utilizes the purification membrane to effectively purify the automobile tail gas, has a simple structure and is convenient for cleaning and regeneration.

Description

technical field [0001] The invention belongs to the field of gas purification, and in particular relates to an automobile tail gas treatment equipment. Background technique [0002] As one of the main sources of air pollution, automobile exhaust contains a large number of harmful substances, including carbon monoxide, nitrogen oxides, hydrocarbons, and solid suspended particles. PM2.5, which has recently become the focus of social attention, belongs to the category of solid suspended particles . In addition to being one of the main sources of PM2.5 in large cities, automobile exhaust is also one of the chief culprits of air pollution in many cities. Photochemical smog is one of its main effects. Due to the serious dispersion and mobility of automobiles, purification treatment Technology brings certain limitations. In the existing purification device, the automobile exhaust cannot be well buffered after entering the purification device, which will also lead to a low utiliza...

In addition to being one of the main sources of PM2.5 in large cities, automobile exhaust is also one of the chief culprits of air pollution in many cities. Photochemical smog is one of its main effects. Due to the serious dispersion and mobility of automobiles, purification treatment Technology brings certain limitations

In the existing purification device, the automobile exhaust cannot be well buffered after entering the purification device, which will also lead to a low utilization rate of the filter layer, and the purification of harmful gases and particulate matter in the automobile exhaust is not sufficient, which is not conducive to environmental protection
