Desulfurization and denitrification integrated flue gas purification device

Abstract

The invention relates to the technical field of flue gas purification devices, and discloses a desulfurization and denitrification integrated flue gas purification device, which comprises a fixed seat, the left side of the upper surface of the fixed seat is fixedly connected with a denitrification cylinder, the middle part of the inner cavity of the denitrification cylinder is fixedly connected with an ammonia gas release device, and the ammonia gas release device comprises a stabilizing frame. According to the desulfurization and denitrification integrated flue gas purification device, flue gas blows the hollow ball to drive the hollow ball to move rightwards, the elastic contraction part is in an extrusion state at the moment, and then the hollow ball is driven to swing leftwards and rightwards, so that the anode plate is knocked; dust collected by the anode plates and dust adhering to the hollow balls can be conveniently shaken off into the dust collecting hopper, the anode plates can be conveniently cleaned, part of wind power in flue gas is effectively converted into kinetic energy for cleaning the electrostatic dust collection device, energy is effectively utilized, and the timeliness of cleaning the electrostatic dust collection device by the desulfurization and denitrification integrated flue gas purification device is improved.

Description

technical field [0001] The invention relates to the technical field of flue gas purification devices, in particular to an integrated flue gas purification device for desulfurization and denitrification. Background technique [0002] Flue gas desulfurization and denitrification technology is a boiler flue gas purification technology applied to the chemical industry that generates many nitrogen oxides and sulfur oxides. Nitrogen oxides and sulfur oxides are one of the main sources of air pollution. Most of the flue gas desulfurization and denitrification technologies It is in the stage of research and industrial demonstration, but because it can realize desulfurization and denitration in one system at the same time, especially as the control standards for nitrogen oxides continue to become stricter, desulfurization and denitrification technology is being paid more and more attention by various countries. [0003] In the denitrification process of existing flue gas desulfurizat...

Problems solved by technology

[0004] The invention provides a desulfurization and denitrification integrated flue gas purification device, which has the advantages of improving the timeliness of the desulfurization and denitrification integrated flue gas purification device for cleaning the electrostatic precipitator, improving the denitrification efficiency of the desulfurization and denitrification integrated flue gas purification device, and improving ammonia gas The advantage of the service life of the release device solves the problem that the existing flue gas desulfurization and denitrification device needs to install an ammonia release device inside the pipeline during the denitrification process. In order to speed up the maintenance of ammonia and nitrogen oxides in the flue gas, the ammonia gas The opening of the release is opposite to the flow direction of the flue gas, which increases the contact area between the ammonia gas and the flue gas, and also increases the contact between the sulfide in the flue gas and the outer surface of the ammonia gas releaser. When the ammonia gas releaser and the sulfide Long-term contact will easily cause corrosion and affect the service life of the ammonia gas releaser, and the existing flue gas desulfurization and denitrification device uses the electric field force to drive the charged dust pears to move to the anode plate when adsorbing the dust in the flue gas , but when the anode plate absorbs a lot of charged dust particles, it is easy to cover the anode plate, which reduces the adsorption effect of the electric field force. At the same time, the sulfide in the flue gas accumulates in the dust and causes corrosion to the anode plate
