Low-temperature plasma purifier

Abstract

The invention relates to a low temperature plasma purifier. The purifier comprises an outer quartz tube, a stainless steel annular steel wire is wound on the outer wall of the outer quartz tube, both ends of the outer quartz tube are respectively provided with a punch hole in which an insulated sealing plug with a center hole is plugged, and a negative electrode probe and a positive electrode probe are respectively inserted into the center holes of the two insulated sealing plugs. A copper tube with one end equipped with a copper elastic sheet is positioned in the outer quartz tube, an inner quartz tube is also positioned in the copper tube, and the copper tube is supported by two polytetrafluoroethylene copper tube support rings positioned in the outer quartz tube. A stainless steel wirewith one end provided with a stainless steel elastic sheet is positioned in the quartz tube, and the stainless steel wire is supported by two polytetrafluoroethylene stainless steel wire support rings positioned in the outer quartz tube. The sealing plug with an air inlet is plugged into one end of the outer quartz tube, and the other end of the outer quartz tube is connected with a detachable catalyst sleeve. The positive electrode probe and the negative electrode probe are electrically connected with a high-voltage pulse power supply, and one end of the stainless steel annular steel wire isconnected with the negative electrode probe. The purifier works under normal temperature and pressure and has no noise, and can realize infinite electric discharge in theory, and the device has advantages of long service life and convenient operation; the range of the low temperature plasma of the device is adjustable, and the catalytic domain can be demounted conveniently for facilitating flexible catalyst replacement.

Description

technical field [0001] The invention relates to a device for purifying harmful gases such as automobile tail gas. In particular, low-temperature plasma can be obtained under normal temperature and pressure. It includes a low-temperature plasma generating device and a metal carrier catalyst. Waste occurs physical and chemical reactions, and then passes through the catalytic zone to remove harmful components in harmful gases. For example, the exhaust gas of automobiles is introduced into the purifier, which can efficiently remove harmful components such as NO, CO, CH, etc., compared with traditional single catalyst purification There are more advantages. Background technique [0002] Since 1913, when the Ford Company of the United States invented the assembly line for automobile production, the automobile manufacturing industry has sprung up. Statistics show that by the end of 2000, the number of cars in the world exceeded 600 million, 116 cars per thousand people, increasing...

AI Technical Summary

Problems solved by technology

[0003] The traditional method of treating automobile exhaust is catalyst purification, but as domestic and foreign requirements for automobile emissions become more and more stringent, the cost of catalyst application is also increasing, especially now that effective catalysts use rare and precious metals, not only the cost High and susceptible to poisoning and inactivation
