Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic dust removal, and specifically relates to a wet electrostatic dust removal device. Background Technique

[0002] Electrostatic precipitation is a method of gas dust removal. It is a dust collection method that uses an electrostatic field to ionize gas so that dust particles are charged and adsorbed onto electrodes. The principle is that when dusty gas passes through a high-voltage electrostatic field, it is electrically separated into positive ions and electrons. When electrons rush towards the positive electrode, they encounter dust particles. After the dust particles combine with negative ions and become negatively charged, they tend to discharge on the surface of the positive electrode and deposit.

[0003] In the actual operation process of the existing wet electrostatic dust removal technology, most of them use metal electrode plates. The dust on the electrode plates can be cleaned through cleaning nozzles. However, the positions of most cleaning nozzles are fixed, resulting in unsatisfactory cleaning effects. Moreover, in order to remove dust, the water consumption is relatively large and is not recycled in time, causing waste of water resources.

[0004] In view of the above problems, the utility model provides a wet electrostatic dust removal device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a wet electrostatic dust removal device.

Finally, the motor is turned on to make the water distribution box move in a reciprocating straight line in the vertical direction, so that the nozzles always face the surface of the electrode plates for flushing, ensuring the cleaning effect. The flushed sewage enters the collection box from the sewage outlet. The filter plate in the collection box will filter the dust. The filtered sewage accumulates at the bottom of the collection box, and then the first water pump is turned on to send the filtered sewage into the water tank for recycling, reducing the waste of water resources, thus solving the problems in the background technique.
