Electrode Nozzle Separation Type Hedge DC Corona Discharge Components for Flue Gas Treatment

Abstract

The invention discloses an electrode nozzle separated hedging direct current corona discharge assembly for flue gas treatment, which comprises two tubular nozzles (1) and one tooth-form electrode (2) which are parallelly arranged; and the two tubular nozzles (1) are synmmetrically located at two sides of the tooth-form electrode (2). The tubular nozzle (1) comprises a jet pipe (3); one end of the jet pipe (3) is an opening end, and the other end is a closed end (5); a row of jet holes (4) are disposed on the jet pipe (3) and are parallel to the axial line of the jet pipe (3); the space n between the jet holes (4) is the same; the tooth-form electrode (2) comprises electrode handles (6) which have a same width and a same thickness and are connected mutually, and an electrode matrix (8); tooth-form tips (7) are respectively disposed at two side surfaces of the electrode matrix (8), have same interval, and correspond to the jet holes (4) on the jet pipe (3); an extending line of an intersection point of the axis of the jet pipe (3) and the end part of the diameter of the jet holes (4) covers the whole tooth-form tips (7).

Description

technical field [0001] The invention belongs to the technical field of energy and environmental protection, and in particular provides an electrode-nozzle-separated hedge direct-current corona discharge assembly for flue gas treatment. Background technique [0002] Plasma flue gas pollutant removal technology is one of the current comprehensive flue gas treatment technologies. It uses gas discharge to generate highly reactive particles to react with pollutant molecules, thereby decomposing and treating various pollutants. At present, more plasma flue gas treatment technologies are used, including electron beam method, pulse corona method and DC corona method. [0003] The process of generating high-energy electrons by the electron beam method will destroy the chemical bonds of the main gas molecules in the flue gas, resulting in the highest content of N in the flue gas. 2 and CO 2 It is decomposed or ionized, which wastes energy, and there are problems such as expensive el...
