Description

Technical Field

[0001] The invention relates to the technical field of electrostatic dust removal, and in particular to a staggered high-voltage electric field dust collector. Background Art

[0002] With the advancement of science and technology, pollutants are constantly generated in life and industry. With the rapid development of cities and industries, the amount of pollutant emissions is also increasing. In order to purify the pollution in the air, dust collectors have emerged to separate dust from flue gas and filter out the flue gas.

[0003] As people's environmental awareness continues to increase and the country pays more and more attention to environmental protection, a high-voltage electrostatic precipitator with low energy consumption, high dust removal efficiency and simple structure has emerged. It uses a high-voltage electric field to ionize the flue gas, and the dust charge in the airflow is separated from the airflow under the action of the electric field.

[0004] However, the existing high-voltage electrostatic precipitators are designed into various structural forms and applied to various occasions. However, the existing high-voltage electrostatic precipitators have complex structures and can only be applied to one scene, and cannot be adjusted according to the actual application scene, resulting in poor user experience. There are also technical problems such as difficulty in disassembly and troublesome cleaning.

[0005] Therefore, the existing high-voltage electrostatic precipitator has the technical problem of being unable to be adjusted according to the actual application scenario, resulting in a poor user experience. Summary of the invention

[0006] In order to overcome the defects of the prior art mentioned above, the present invention proposes an interlaced high-voltage electric field dust collector, which solves the technical problem that the existing high-voltage electrostatic precipitator cannot be adjusted according to the actual application scenario, resulting in poor user experience.

[0007] In order to achieve the above object, the technical solution specifically adopted by the present invention is:

[0008] A staggered high-voltage electric field dust collector, the staggered high-voltage electric field dust collector comprising: a plurality of low-pressure dust collecting parts and high-pressure dust collecting parts arranged in sequence at intervals, the low-pressure dust collecting parts and the high-pressure dust collecting parts both comprising substrates, adjacent surfaces of the substrates of the low-pressure dust collecting parts and the high-pressure dust collecting parts are provided with a plurality of dust collecting plates; a plurality of discharge metal needles, the discharge metal needles are arranged on the dust collecting plates on the high-pressure dust collecting parts and extend along the airflow direction; a connecting part, used to connect two adjacent low-pressure dust collecting parts and simultaneously connect a high-pressure dust collecting part, the high-pressure dust collecting part being connected to the two adjacent low-pressure dust collecting parts of the high-pressure dust collecting part via the connecting part; a power supply, providing a stable current for the dust collecting parts and the discharge metal needles.

[0009] In the above-disclosed staggered high-voltage electric field dust collector, two adjacent low-pressure dust collecting parts are connected to the high-pressure dust collecting part through a connecting piece, so that the high-pressure dust collecting part is connected to the two low-pressure dust collecting parts adjacent to the high-pressure dust collecting part through the connecting piece. Such a connection enables the high-pressure dust collecting part and the two low-pressure dust collecting parts adjacent to the high-pressure dust collecting part to form a dust collecting assembly. The dust collecting part is assembled by a number of integrated components and can be disassembled or combined according to different needs and then adjusted in size to adapt to different application scenarios. It solves the technical problem that the existing high-voltage electrostatic precipitator cannot be adjusted according to the actual application scenario, resulting in a poor user experience.

[0010] Furthermore, the dust collecting plate on the high-pressure dust collecting component is staggered with the dust collecting plate on the adjacent low-pressure integrated component. The staggered dust collecting plate structure can form multiple parallel electric fields to make the electric field lines more dense, so that the dust collecting plate can better adsorb impurities and ions in the airflow, achieving a better dust removal effect.

[0011] Furthermore, two adjacent low-pressure dust collecting parts form a storage space, and the high-pressure dust collecting part is arranged in the storage space. Such a structural design can make the high-pressure dust collecting part completely surrounded by the low-pressure dust collecting plate, thereby avoiding leakage of the high-pressure dust collecting part.

[0012] Furthermore, the discharge metal needle is arranged on one end of the dust collecting plate away from the base plate, so that the discharge metal needle is located at the center of the surrounding electric field, so that the electrons generated by the discharge metal needle are evenly diffused into the air, so that the dust in the air absorbs enough negative charges, and then the dust is better adsorbed on the dust collecting plate through the action of Coulomb force, achieving a better dust removal effect.

[0013] Furthermore, the outer surface of the connecting piece is provided with a group of low-pressure slots for connecting two adjacent low-pressure dust collecting pieces, and the inner surface of the connecting piece is provided with a group of high-pressure slots for connecting the high-pressure dust collecting piece.

[0014] Furthermore, both left and right ends of the high-pressure dust collecting component are provided with dust collecting plates connected to the high-pressure slot, and the high-pressure slot includes a continuously or discontinuously arranged high-pressure boss, and the high-pressure boss is connected to the dust collecting plate between the discharge metal needles.

[0015] Furthermore, both left and right ends of the low-pressure dust collecting parts are provided with dust collecting plates connected to the low-pressure card slots, and the dust collecting plates are provided with splicing pieces, and the dust collecting plates corresponding to the adjacent low-pressure dust collecting parts are spliced ​​by the splicing pieces. The splicing pieces connect the dust collecting plates on the adjacent low-pressure dust collecting parts, thereby making the connection of the dust collecting parts more stable, avoiding the separation of the adjacent low-pressure dust collecting parts due to the looseness of the dust collecting plates, thereby loosening the dust collector structure and affecting the dust removal effect.

[0016] Furthermore, the splicing parts include splicing blocks and splicing grooves, and the splicing blocks and splicing grooves are respectively arranged on the dust collecting plates corresponding to the adjacent low-pressure dust collecting parts.

[0017] Furthermore, the dust collecting plate connected to the connecting member on the low-pressure dust collecting member is provided with a parallel connection member, and the low-pressure dust collecting members are connected in parallel through the parallel connection member. Assembling and connecting the low-pressure dust collecting members in parallel through the parallel connection member can make the dust collector adapt to more application scenarios and meet different scenario requirements.

[0018] Furthermore, the connecting member includes a C-shaped groove and a parallel block, and the C-shaped groove and the parallel block are respectively arranged on the dust collecting plates corresponding to the adjacent low-pressure dust collecting members. The cooperation of the C-shaped groove and the parallel block can not only connect the dust collecting plates corresponding to the adjacent low-pressure dust collecting members to each other, but also connect the low-pressure dust collecting members in parallel, which has a simple structure and achieves the effect of one against two.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the staggered high-voltage electric field dust collector disclosed in the present invention, two adjacent low-pressure dust collecting parts are connected to the high-pressure dust collecting parts through a connecting piece, so that the high-pressure dust collecting part is connected to the two low-pressure dust collecting parts adjacent to the high-pressure dust collecting part through the connecting piece. Such a connection enables the high-pressure dust collecting part and the two low-pressure dust collecting parts adjacent to the high-pressure dust collecting part to form a dust collecting assembly. The dust collecting part is assembled by a number of integrated components and can be disassembled or combined according to different needs and then adjusted in size to adapt to different application scenarios. It solves the technical problem that the existing high-voltage electrostatic precipitator cannot be adjusted according to the actual application scenario, resulting in a poor user experience.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Please combine Figure 1 and Figure 2 The first embodiment of the present invention provides a staggered high-voltage electric field dust collector, which includes: a plurality of low-pressure dust collecting parts 1 and high-pressure dust collecting parts 2 arranged in sequence, the low-pressure dust collecting parts 1 and the high-pressure dust collecting parts 2 both include a substrate 01, and adjacent surfaces of the substrates 01 of the low-pressure dust collecting parts 1 and the high-pressure dust collecting parts 2 are provided with a plurality of dust collecting plates 02. A plurality of discharge metal needles 3, the discharge metal needles 3 are arranged on the dust collecting plates 02 on the high-pressure dust collecting parts 2 and extend along the airflow direction. A connector 4 is used to connect two adjacent low-pressure dust collecting parts 1 and a high-pressure dust collecting part 2 at the same time, and the high-pressure dust collecting part 2 is connected to two low-pressure dust collecting parts 1 adjacent to the high-pressure dust collecting part 2 through the connector 4; a power supply 5 provides a stable current for the dust collecting parts and the discharge metal needles 3.

[0036] It should be noted that in this solution, there is no restriction on the voltage of the low-voltage dust collecting part 1 and the voltage of the high-voltage dust collecting part 2. The low voltage and the high voltage are just a manifestation of the voltage difference. Specifically, in this embodiment, the voltage of the low-voltage dust collecting part 1 is 0V, and the voltage of the high-voltage dust collecting part 2 is 1 to 9 kV. The voltage of the power supply 5 is 1 kV to 9 kV.

[0037] It can be understood that in the above-disclosed staggered high-voltage electric field dust collector, two adjacent low-pressure dust collecting parts 1 are connected to the high-voltage collection at the same time through the connecting part 4, so that the high-pressure dust collecting part 2 is connected to the two low-pressure dust collecting parts 1 adjacent to the high-pressure dust collecting part 2 through the connecting part 4. Such a structure allows the high-pressure dust collecting part 2 and the two low-pressure dust collecting parts 1 adjacent to the high-pressure dust collecting part 2 to be combined to form a dust collecting assembly. The dust collecting parts are assembled by a number of integrated components and can be disassembled or combined according to different needs and then adjusted in size to adapt to different application scenarios. It solves the technical problem that the existing high-voltage electrostatic precipitator cannot be adjusted according to the actual application scenario, resulting in a poor user experience.

[0038] The dust collecting plate 02 on the high-pressure dust collecting part 2 is staggered with the dust collecting plate 02 on the adjacent low-pressure integrated part 1. The staggered structure of the dust collecting plate 02 can form multiple parallel electric fields to make the electric field lines more dense, so that the dust collecting plate 02 can better adsorb impurities and ions in the airflow, achieving a better dust removal effect.

[0039] Two adjacent low-pressure dust collecting parts 1 form a storage space, and the high-pressure dust collecting part 2 is arranged in the storage space. Such a structural design can make the high-pressure dust collecting part 2 completely surrounded by the low-pressure dust collecting plate 02, thereby preventing the high-pressure dust collecting part 2 from leaking electricity.

[0040] See also Figure 2 , the discharge metal needle 3 is arranged on the end of the dust collecting plate 02 away from the substrate 01. A placement groove 123 is provided on the end of the dust collecting plate 02 away from the substrate 01, and the bottom of the discharge metal needle 3 is placed in the placement groove 123. Such a structural design makes the discharge metal needle 3 located at the center of the surrounding electric field, so that the electrons generated by the discharge metal needle 3 are evenly diffused into the air, so that the dust in the air absorbs enough negative charges, and then the dust is better adsorbed on the dust collecting plate 02 through the action of Coulomb force, achieving a better dust removal effect. And the design of the placement groove 123 can make the discharge metal needle 3 more stable, and at the same time make the discharge metal needle 3 easy to load and unload, and easy to clean and replace.

[0041] The outer surface of the connector 4 has a group of low-pressure slots 41 for connecting two adjacent low-pressure dust collecting parts 1, and the inner surface of the connector 4 is provided with a group of high-pressure slots 42 for connecting the high-pressure dust collecting part 2. The left and right ends of the high-pressure dust collecting part 2 are provided with dust collecting plates 02 connected to the high-pressure slots 42, and the high-pressure slots 42 include high-pressure bosses 421 that are continuously or intermittently arranged, and the high-pressure bosses 421 are connected to the dust collecting plate 02 between the discharge wires. It should be noted that this scheme does not impose any restrictions on the design of the connection method between the connector 4 and the low-pressure dust collecting part 1 and the high-pressure dust collecting part 2. The connection method between the connector 4 and the low-pressure dust collecting part 1 and the high-pressure dust collecting part 2 can be a snap connection, or it can be a detachable connection method such as a magnetic connection or a threaded connection. Specifically, in this embodiment, the connection method between the connector 4 and the low-pressure dust collecting part 1 and the high-pressure dust collecting part 2 is a snap connection. Similarly, the present solution does not impose any restrictions on the specific connection method of the connecting member 4 with the low-pressure dust collecting member 1 and the high-pressure dust collecting member 2 by snap-fitting.

[0042] Please combine Figure 3 and Figure 4 The left and right ends of the low-pressure dust collecting part 1 are both provided with dust collecting plates 02 connected to the low-pressure card slot 41, and the dust collecting plates 02 are provided with splicing pieces 121, and the dust collecting plates 02 corresponding to the adjacent low-pressure dust collecting parts 1 are spliced ​​by the splicing pieces 121. The splicing pieces 121 include splicing blocks 1211 and splicing grooves 1212, and the splicing blocks 1211 and the splicing grooves 1212 are respectively arranged on the dust collecting plates 02 corresponding to the adjacent low-pressure dust collecting parts 1. The splicing pieces 121 connect the dust collecting plates 02 on the adjacent low-pressure dust collecting parts 1, thereby making the connection of the dust collecting parts more stable, avoiding the separation of the adjacent low-pressure dust collecting parts 1 due to the looseness of the dust collecting plates 02, thereby loosening the dust collector structure and affecting the dust removal effect.

[0043] See also Figure 5 , the dust collecting plate 02 connected to the connecting member 4 on the low-pressure dust collecting part 1 is provided with a parallel connecting member 122, and the low-pressure dust collecting part 1 is connected in parallel through the parallel connecting member 122. Assembling and connecting the low-pressure dust collecting parts 1 in parallel through the parallel connecting member 122 can make the dust collector adapt to more application scenarios and meet the needs of different scenarios. Specifically, the parallel connecting member 122 includes a C-shaped groove 1221 and a parallel block 1222, and the C-shaped groove 1221 and the parallel block 1222 are respectively arranged on the dust collecting plates 02 corresponding to the adjacent low-pressure dust collecting parts 1. The dust collecting plates 02 at the left and right ends of the same low-pressure dust collecting part 1 are respectively provided with a C-shaped groove 1221 and a parallel connecting block. The cooperation of the C-shaped groove 1221 and the parallel block 1222 can not only connect the dust collecting plates 02 corresponding to the adjacent low-pressure dust collecting parts 1 to each other, but also connect the low-pressure dust collecting parts 1 in parallel. The structure is simple and achieves the effect of one against two.

[0044] The working principle of this scheme is that the airflow flows into the dust collector from the outside, and first passes through the discharge metal needle 3 pair to ionize the airflow through the tip discharge. Under the action of the high-voltage electric field, the impurities in the airflow absorb enough negative charge and are adsorbed on the dust collecting plate 02 through the Coulomb force. At the same time, harmful microorganisms such as bacteria, viruses, molds, etc. die under the action of high-voltage static electricity, thereby controlling the number of harmful viruses and bacteria in the airflow and achieving a sterilization and disinfection effect. Finally, the airflow flows out from the other end of the dust collector to obtain clean and fresh air. The high-pressure dust collecting part 2 and the two low-pressure dust collecting parts 1 adjacent to the high-pressure dust collecting part 2 are combined to form a dust collecting component. The dust collecting parts are assembled by a number of integrated components and can be disassembled or combined according to different needs, and then adjusted in size to adapt to different application scenarios. It solves the technical problem that the existing high-voltage electrostatic precipitator cannot be adjusted according to the actual application scenario, resulting in a poor user experience.
