Description

Technical Field

[0001] The utility model relates to the technical field of chemical dust removal, in particular to an electrostatic adsorption structure of a chemical dust removal device. Background Art

[0002] As an efficient dry dust removal technology, electrostatic adsorption has been widely used in the field of chemical production, especially in the treatment of flue gas purification containing a large number of fine particles. Its significant advantage is that it can capture dust with a particle size as small as submicron level, greatly improving the dust removal efficiency and air quality. In the chemical production process, many links will produce dust-rich tail gas, such as incompletely reacted materials escaping from the reactor, solid particles produced in the drying process, and dust produced by crushing and screening operations. These dusts will not only cause atmospheric environmental pollution, but may also pose a threat to human health and equipment safety. Traditional dust removal methods such as filtration and cyclone separation have limited effects on the capture of fine particles. Therefore, electrostatic adsorption dust removal technology came into being due to its unique dust removal mechanism.

[0003] The basic working principle of the electrostatic adsorption dust removal device is based on the effect of electric field force on dust particles. The device is mainly composed of a corona discharge area and a dust collection area. In the corona discharge area, by applying high voltage direct current between a set of anodes and cathodes, the gas is ionized, and the released electrons and positive ions migrate rapidly and move closer to the corresponding polarity plates. When dust particles pass through the electric field, they will capture charges. Under the action of the electric field force, the charged particles move quickly to the dust collecting plates of opposite polarity and are firmly adsorbed on the dust collecting plates, completing the separation of dust and airflow.

[0004] The existing electrostatic adsorption device does not take into account that dust is easily accumulated on the anode when in use, which affects the generation of static electricity, causing the subsequent dust treatment effect to gradually decrease until it cannot be used. Therefore, it is necessary to propose an electrostatic adsorption structure for a chemical dust removal device. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes an electrostatic adsorption structure for a dust removal device for chemical industry.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

After the sector gear is disengaged from the fixed latch tooth, the reaction force of the compressed functional spring pushes the movable plate to reset the anode porous plate.
