Vehicle tail gas purifying device

Abstract

The invention discloses a vehicle tail gas purifying device, which comprises an indirect cooler and a direct purification cooler which are connected sequentially, wherein the indirect cooler uses indirect water cooling to reduce the temperature of tail gas; and in the direct purification cooler, the tail gas is atomized and directly contacts purification media to realize cooling and temperature reduction. The chamber body of the direct purification cooler is also provided with at least one baffle which forms an included angle of between 0 and 40 degrees with a horizontal plane; and the baffle is positioned above the liquid level of the purification media, and at least partial baffle is opposite to an outlet of a gas channel. The vehicle tail gas purifying device holds back liquid drops brought out by the tail gas in the chamber body through the baffle with a reasonable structure, and prevents the liquid drops from causing secondary pollution.

Description

technical field [0001] The present invention relates to a device for cooling and purifying automobile exhaust, more specifically, relates to a device for reducing temperature, reducing noise, A car exhaust purification device with purifying effect. Background technique [0002] Commonly used internal combustion engines will emit high-temperature exhaust gas to the atmosphere during combustion. These exhaust gases are mainly composed of hydrocarbons, nitrous oxide, and carbon monoxide. Chemical composition of solid particles. [0003] The temperature of the combustion exhaust gas in the exhaust pipe of the automobile is about 700 degrees Celsius, while the temperature of the combustion exhaust gas discharged by the internal combustion engine running at full load is as high as 750-800 degrees Celsius. Therefore, even if these exhaust gases are first treated by the muffler and then discharged into the atmosphere, the large amount of noise and chemical pollution that will be g...

Problems solved by technology

[0006] But in recent years, in the process of actually implementing this patent, I found that the product still has the following shortcomings: the exhaust gas pressure of the automobile engine in operation is relatively high. After entering the direct cooling purifier, although it has passed through the atomizer The pressure is greatly reduced, but the exhaust gas after atomization is still jetted out of the liquid surface

During this process, the exhaust gas will bring out a large number of liquid droplets, which may be water or chemicals, and enter the subsequent exhaust gas discharge pipeline with the exhaust gas, which may cause corrosion and secondary pollution to the pipeline
