Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic separation, in particular to an electrostatic dust removal impact device which can be quickly disassembled and assembled. Background Art

[0002] The principle of electrostatic dust removal is to pass a high-voltage electric field with a flashover frequency of 10 times / minute through the anode plate and the cathode plate to bind the particles passing through the electric field. Under the combined effect of gravity and the intermittent electric field, the particles fall into the dust removal bag to achieve the environmentally friendly effect of collecting and removing dust.

[0003] In waste heat power generation, the dust removal device operates for a long time in a high temperature environment (exhaust temperature is between 350℃-380℃) for 24 hours without interruption. A large amount of dust will be adsorbed on the electrode plate, which will affect the binding effect of the electric field on the dust and the dust removal effect. Therefore, it is generally necessary to use a mechanical method to knock the electrode plate to shake off the dust accumulated on the electrode plate. The current electrostatic precipitator equipment generally uses a striking plate or a striking hammer to directly knock the attached plate welded on the electrode frame to achieve the vibration and fall of the dust. The attached plate will be penetrated when it is always in a struck condition, which will affect the vibration of the electrode plate and the falling of the dust, thereby affecting the dust removal effect. Therefore, after the attached plate is broken down, it needs to be replaced.

[0004] Currently, when replacing an auxiliary plate, workers are required to cut, grind, and weld a new auxiliary plate. However, since the dust removal device is in a dusty and high-temperature environment, there is a risk of dust explosion when replacing the auxiliary plate, which poses a certain safety hazard.
