Interverted Electron Beam Reflection Resonance Avalanche Sulfur Nitrate Removal System

Abstract

The invention relates to a mutually perpendicular electron-beam reflection resonance avalanche desulfuration and denitration system, and belongs to the field of electrostatic dust removal. The main technical problem to be solved by the invention is to increase the electron quantity of an electron beam for oxidizing SO2 and NOx more effectively and then removing sulfur and nitrogen oxides. The system comprises a gas outlet, an outlet left wall, a high-voltage positive plate, a lower connecting wall, a high-voltage power supply, an electron gun, an illuminating window, an inlet left wall, a gasinlet, an inlet right wall, an incident electron beam, a reactor, an upper reflecting wall, a first reflecting electron beam, a lower reflecting wall, a main negative plate, a second reflecting electron beam, an auxiliary negative plate and an outlet right wall. The system is characterized in that the gas outlet is connected with the gas inlet through the reactor, the outlet left wall is connectedwith the lower connecting wall through the high-voltage positive plate, the lower connecting wall is connected with the inlet left wall through the illuminating window, the inlet left wall is connected with the illuminating window through the electron gun, and the illuminating window is connected with the upper reflecting wall through the incident electron beam. The system provided by the invention is mainly used in the field of electrostatic dust removal.

Description

technical field [0001] The invention belongs to the field of electrostatic dust removal, in particular to a system for removing sulfur and nitric acid by reflecting and resonating an avalanche of vertical electron beams. Background technique [0002] Sulfur and nitrogen oxides are important factors of air pollution, so desulfurization and nitrogen oxides are important tasks for air pollution control. The use of electron beam dry desulfurization, nitrogen oxides is a common method. Cool the exhaust gas at a temperature of 150 degrees Celsius to about 70 degrees Celsius, add a small amount of ammonia according to the concentration of sulfur dioxide and nitrogen oxides in the gas, and then send the mixed gas containing ammonia into the reactor. After electron beam irradiation, SO in the exhaust 2 and NO x Strongly oxidized by the electron beam, it is oxidized into sulfuric acid and nitric acid in a very short time, and these acids react with the surrounding ammonia to form (...

AI Technical Summary

Problems solved by technology

The number of electrons in the electron beam vs. SO 2 and NO x The oxidation reaction plays a very important role, but the number of electron gun emissions alone cannot meet the needs of the oxidation reaction.
