Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust removal technology, and more specifically, to a multi-stage purification dry and wet electrostatic dust removal device. Background Technology
[0002] Electrostatic precipitator (ESP) is a gas dust removal method that utilizes an electrostatic field to ionize the gas, causing dust particles to become charged and adhere to electrodes. The principle is that when dust-laden gas passes through a high-voltage electrostatic field, it is electrically separated into positive ions and electrons. Electrons, traveling towards the positive electrode, encounter dust particles; the dust particles combine with the negative ions, becoming negatively charged, and then discharge and deposit on the positive electrode surface. Currently, wet ESP is widely used in the purification of flue gas after desulfurization towers in chemical, metallurgical, and coal-fired power plants, and is one of the most effective methods for controlling dust emissions.
[0003] However, existing electrostatic dust removal methods are relatively simple, only using dry or wet electrostatic dust removal for dust removal operations, which cannot effectively classify and treat dust. In addition, in dry electrostatic dust removal, a lot of dust will adhere to the surface of the dry electrode plate during use, which is inconvenient to clean and affects the later use effect. Furthermore, in wet electrostatic dust removal, the spray assembly uses a fixed type to clean the dust on the wet electrode plate, resulting in poor cleaning effect on the surface of the wet electrode plate. Utility Model Content
[0004] The purpose of this invention is to solve the problems mentioned in the background art, and to propose a multi-stage purification dry and wet electrostatic dust removal device.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A multi-stage purification dry and wet electrostatic dust removal device includes a mounting frame with a processing box on the frame. The processing box is divided into a dry chamber and a wet chamber by a partition, and the dry chamber and wet chamber are connected by a connecting pipe on the partition. The outside of the processing box is equipped with a dust inlet component connected to the dry chamber and an exhaust component connected to the wet chamber. The dry chamber is equipped with a vibration component with a dry electrode plate mounted on it. The wet chamber is equipped with a wet electrode plate, a drive component, and a spray component.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:
[0024] See attached document Figure 1 -Appendix Figure 4 As shown, a multi-stage purification dry and wet electrostatic dust removal device includes a mounting frame 1, on which a processing box 2 is mounted. The processing box 2 is divided into a dry chamber 22 and a wet chamber 23 by a partition 21, and the dry chamber 22 and wet chamber 23 are connected by a connecting pipe 24 disposed on the partition 21. The outside of the processing box 2 is provided with a dust inlet assembly 3 connected to the dry chamber 22 and an exhaust assembly 4 connected to the wet chamber 23. The dry chamber 22 is provided with a vibration assembly 5, on which a dry electrode plate 6 is mounted. When the vibration assembly 5 is activated, a sudden and brief force is applied to the dry electrode plate 6, causing the dry electrode plate 6 to vibrate or bend rapidly. Due to inertia, the dust adhering to the surface of the dry electrode plate 6 cannot move synchronously with the dry electrode plate 6, thus separating from the surface of the dry electrode plate 6 and falling off. The wet chamber 23 is equipped with a wet electrode plate 7, a drive assembly 8, and a spray assembly 9. The drive assembly 8 is connected to the spray assembly 9 so that the drive assembly 8 operates to make the spray assembly 9 perform a lifting spray action on the wet electrode plate 7. Through the up-and-down moving spray, it can be ensured that the water flow impacts the surface of the wet electrode plate 7 at different angles, enhancing the rinsing effect on the dust particles that are highly adhesive and difficult to remove. At the same time, it avoids the cleaning dead corners that may exist in fixed position spraying, ensuring that all parts can be thoroughly cleaned.
[0025] In the specific implementation process, by combining dry electrostatic precipitator and wet electrostatic precipitator, the overall dust removal efficiency and dust removal effect can be significantly improved. The dust enters the dry chamber 22 through the dust inlet component 3. After the preliminary treatment by the dry electrode plate 6, most of the large particles in the dust have been removed. Then it enters the wet chamber 23, where the wet electrode plate 7 captures and treats fine particles, aerosols and sticky substances. Finally, it is discharged through the exhaust component 4.
