Abstract

The invention discloses a wet-type pulse corona smoke gas treatment reactor. The reactor comprises a shell; the lower end of the shell is provided with a gas inlet; the upper end of the shell is provided with a gas outlet; the inner wall of the shell clings to and is provided with a running water polar plate; the upper part of the running water polar plate is provided with a water sprayer; the bottom of the shell is provided with a water outlet; a sorbent is ejected from the water sprayer and flows from top to bottom along the running water polar plate; and finally, the sorbent is collected in the water outlet and flows to a feed discharge pool; the center of the shell is provided with an acicular corona wire; the acicular corona wire and the running water polar plate form two electrodes for corona discharging; the running water polar plate is connected with positive pulse high voltage; and the acicular corona wire is connected with negative pulse high voltage. The wet-type pulse corona smoke gas treatment reactor compounds non-thermal equilibrium plasma technology, physical adsorption technology and chemical absorption technology, realizes high-efficiency removing of PM2.5, SO2 and NOx in the same reactor, greatly simplifies a smoke gas treatment system and reduces investment and operating cost.

Description

technical field [0001] The invention relates to a reactor for treating flue gas, in particular to a reactor for treating flue gas with wet pulse corona. Background technique [0002] In recent years, the application of plasma technology in the field of flue gas treatment has received more and more attention. This technology usually uses gas discharge to generate active particles such as high-energy electrons, free radicals, and positive and negative ions with strong reactivity, which chemically react with various pollutant molecules in the flue gas, and finally transform the flue gas pollutants into harmless substances. The biggest feature of this technology is that it can efficiently and conveniently destroy and decompose various pollutants, the equipment used is simple, the space occupied is small, and it is suitable for complex working environments. In plasma flue gas treatment technology, the key is how to generate highly reactive plasma. In the case of close to atmosp...
