Abstract

The invention relates to the technology of purifying organic waste gas in the industry and aims to provide a low-temperature plasma generating device. A reactor of the device comprises an electric corona tube support, insulators, an upper baffle and a lower baffle in a sequential connection mode, and n plasma reacting cavities are formed in parallel. Outer shells of the reacting cavities are in a hollow cylinder shape, and electric corona tubes and the outer shells of the reacting cavities are coaxial. Multiple bars of discharging fluff made of metal material are evenly distributed on the outer walls of the electric corona tubes in a spiral step shape. Inward extending lines of the discharging fluff pass through the axes of the electric corona tubes. The electric corona support is provided with supporting pillars perpendicular downwards, the supporting pillars are sleeved with the electric corona tubes, and rain caps are arranged at the bottoms of the electric corona tubes. High-energy electrons, ions, atoms in an excited state, free radical particles and other high-activity substances generated by the device are improved by 35% on the basis of the same-size reactor, and effective reaction space is enlarged. Because fluff-shaped electrodes are adopted, the probability of breakdown of a positive electrode and a negative electrode is greatly reduced, and energy consumption is greatly reduced.

Description

technical field [0001] The invention relates to industrial organic waste gas purification technology, in particular to a low-temperature plasma generating device for purification of volatile organic waste gas and malodorous gas. technical background [0002] Low-temperature plasma, also known as non-equilibrium plasma, is the fourth state of matter after solid, liquid, and gas. Low-temperature plasma often produces a large number of high-energy electrons, ions, excited atoms and free radical particles and other highly active substances by gas discharge during the exhaust gas purification process. These substances bombard organic exhaust gas molecules or odorous gas molecules and break their internal chemical bonds. Promote its degradation to produce CO 2 and H 2 O, so as to achieve the purpose of purification; the application of this technology breaks through the constraints of decomposing pollutants by chemical reaction and many chemical reaction conditions in the past. ...
