Flue gas condensation and electrostatic treatment device and treatment technology

Abstract

The invention provides a flue gas condensation and electrostatic treatment device and treatment technology, and belongs to the field of purification treatment of a flue gas. The flue gas is treated by the flue gas condensation and electrostatic treatment device. The device comprises liquid channel layers arranged in multiple layers, so that the flue gas and a cooling medium circulate in different liquid channels respectively and finish heat exchange; the surface of the bottom part of the liquid channel into which the flue gas is introduced is coated with a conductive material; the conductive material is connected with a positive electrode of a power supply system to form an anode plate, so that a strong oxidation environment is formed in the liquid channel after electrification; and the anode plate is matched with a negative electrode of the power supply system to form an adsorption electric field in the liquid channel. According to the flue gas condensation and electrostatic treatment device and treatment technology, pollutants of sulfur oxide, nitric oxide, PM2.5 and the like in the flue gas can be effectively removed; a lot of water is also recycled; and the problem that the environment is polluted since the water is combined with the pollutants to form acidy white smoke after being discharged into atmosphere is solved.

Description

technical field [0001] The invention relates to the technical field of flue gas clean discharge in boiler, electric power and petrochemical industries, in particular to a flue gas condensation electrostatic treatment device and a treatment process. Background technique [0002] In recent years, as the smog has become more and more serious and the requirements for environmental protection have become increasingly stringent, the situation to achieve the goal of energy conservation and emission reduction is very severe. In particular, a series of policies and related emission standards formulated to promote energy conservation and emission reduction have faced boilers, The amount of flue gas after wet desulfurization in electric power, petrochemical and other industries is large, and the H after wet desulfurization 2 O content is high, there is still a certain amount of NO in the flue gas x , SO 2 The total amount of pollutants such as PM2.5 and PM2.5 is large, and the aeroso...
