Abstract

The invention relates to an SCR reaction system for flue gas denitration based on coupling of an electrostatic field. The SCR reaction system is characterized by comprising: a shell used for placing a device; unit boxes, which are divided into a plurality of groups, wherein each group comprises a plurality of unit boxes, and each group is uniformly arranged on a frame on the inner wall of the shell; integral denitration catalyst units, which are assembled in the single unit boxes in parallel along the flue gas flowing direction and are used for flue gas denitration; an electric field assembly, which comprises a direct-current power source generator, a high-voltage electrode, wires and a voltage regulator, wherein the direct-current power supply and the voltage regulator form an electrostatic field with the integral denitration catalyst units through the wires; and a central control module, which comprises a temperature detector, wherein one end of the temperature detector is connected with the metal matrixes of the integral denitration catalyst units so as to measure the temperature of the integral denitration catalyst units in real time, the other end of the temperature detector outputs a temperature signal to the external central control module, and the central control module calculates the received temperature signal and controls the voltage regulator to carry out regulation.

Description

technical field [0001] The invention relates to the technical field of SCR reactors, in particular to an SCR reaction system based on electrostatic field coupling flue gas denitrification. Background technique [0002] Nitrogen oxides (NO X ) is one of the main pollutants in the atmosphere and is the top priority of pollution control. At present, the selective catalytic reduction (SCR) technology using NH3 or urea as the reducing agent is a widely used flue gas denitrification technology, but it faces a series of problems and challenges. With the increasing requirements for environmental protection, it is urgent The implementation of more mature denitrification technologies is required. [0003] With the introduction of the latest "Emission Standard of Pollutants for Coking Chemical Industry" (GB16171-2012), coke oven flue gas must be denitrified by more advanced denitrification process to meet stricter nitrogen oxide emission requirements. At present, SCR denitrification...
