Mixed gas treatment equipment based on plasma technology

Abstract

The invention discloses mixed gas treatment equipment based on a plasma technology. The equipment comprises an SF6 degradation host machine and a power supply part; the host machine comprises a mixed gas box, a plasma discharge matrix and a tail gas collection box which are densely assembled together; purified water fills the bottom of the mixed gas box, and gas to be degraded in the mixed gas box is mixed with diluent gas and water vapor to form mixed gas; one end of the plasma discharge matrix is connected with the mixed gas box, so that the plasma discharge matrix can be used for carrying out plasma degradation treatment on the mixed gas; the tail gas collection box is connected with the other end of the plasma discharge matrix, and alkaline absorption liquid is contained in the tail gas collection box, and the tail gas collection box is used for washing the degraded gas and then discharging the gas through an exhaust pipe. The gas mixing device for mixing SF6 gas to be degraded and diluent gas and the washing and collecting device for tail gas subjected to discharge degradation are integrated in front of and behind the discharge matrix, so that the main part of the whole equipment can be formed, and the equipment is small and portable and can be used in various occasions.

Description

technical field [0001] The invention belongs to the technical field of chemical or biological purification of exhaust gas such as engine exhaust gas, flue gas, smog, flue gas or aerosol, and specifically relates to a sulfur hexafluoride treatment equipment based on plasma technology. Background technique [0002] With the development of the global economy, environmental problems have become increasingly prominent, and various environmental pollutions have emerged one after another, which has seriously threatened the safety of human life. For the safety of human beings, it is imminent to control the environment. In recent years, many high-tech technologies for environmental governance have emerged, including low-temperature plasma technology. Low-temperature plasma technology has high efficiency, low energy consumption, large processing capacity, and simple operation, and has significant advantages in the treatment of some toxic and difficult-to-degrade wastes. [0003] Due ...

AI Technical Summary

Problems solved by technology

[0004] Currently on SF 6 There are many kinds of degradation treatment devices, but most of them are bulky or very heavy, not easy to carry, and cannot be used in various occasions

For example, in CN201820498750.4, the process of degrading gas by dielectric barrier discharge occurs in the transformer oil, which makes the device bulky and fixed in use; another example is the gas treatment device proposed in CN201820496661.1. pool or store gas cylinders, reducing the portability of the unit
