[0034] It should be noted that the orientation words such as "left" and "right" in the following text are defined based on the drawings in the specification. The first direction, the second direction and the third direction can be perpendicular to each other.

[0035] With the progress of social industrialization, flue gas emissions, automobile exhaust emissions and dust spread at construction sites, etc. make the dust particles in the air more and more, which has a significant impact on people's health, so the dust collector becomes an indispensable electrical equipment, and the electrostatic dust removal device is favored by everyone because of its simple structure. In some embodiments, the electrostatic dust removal device mainly includes a charging assembly 1 and a dust collecting assembly 2. When air flows through the charging assembly 1, the air is ionized by high voltage, so that the dust and other particles in the air are positively charged. The downstream dust collecting assembly 2 is connected to a negative high voltage, and a negative high voltage electric field is formed inside the dust collecting assembly 2. When the particles with positive charge flow through the negative high voltage electric field with air, the particles are adsorbed inside the dust collecting assembly 2, thereby realizing the dust removal and purification function.

[0036] The utility model provides a kind of electrostatic dust removal device, dust particles in air and electrode plate 21 of dust collecting assembly 2 are physically isolated by isolation plate 3, can effectively prevent dust particles to be accumulated on electrode plate 21 of dust collecting assembly 2, without disassembling and cleaning electrode plate 21, only need to clean electrostatic dust removal device by dismounting and cleaning isolation plate 3, simple operation, convenient and fast.The utility model also provides an air cleaning equipment comprising the above-mentioned electrostatic dust removal device, which can improve the service life of the equipment.

[0037] Please refer to Figure 1 And Figure 2 An electrostatic dust removal device includes a charging assembly 1, a dust collecting assembly 2 and an isolation plate 3.

[0038] Specifically, the dust collecting assembly 2 is provided with a passage, and the dust collecting assembly 2 is located on one side of the air outlet of the charging assembly 1. When air flows through the charging assembly 1, dust particles in the air are induced to charge under the action of the electric field formed by the charging assembly 1 and flow out of the air outlet of the charging assembly 1. The isolation plate 3 is detachably arranged in the passage of the dust collecting assembly 2. After the charged dust particles flow out of the charging assembly 1, they pass through the isolation plate 3. The charged dust particles are adsorbed on the isolation plate 3 arranged in the passage of the dust collecting assembly 2 under the action of the electric field of the dust collecting assembly 2, realizing the function of dust removal. When cleaning the electrostatic dust removal device, only the isolation plate 3 needs to be disassembled and cleaned, which can clean the dust particles collected on the electrostatic dust removal device. The charging assembly 1 and the dust collecting assembly 2 do not need to be disconnected from the power supply or disassembled for cleaning. Compared with the prior art, the cleaning process of the electrostatic dust removal device is greatly simplified, and the cleaning difficulty is reduced.

[0039] The charged component 1, the isolation plate 3 and the dust collecting component 2 are in a plate shape in the embodiment, and are stacked in a direction perpendicular to the electrostatic dust collector. The isolation plate 3 covers the surface of the dust collecting component 2 and partially overlaps the dust collecting component 2 in the direction perpendicular to the electrostatic dust collector. In some embodiments, air passes through the three components in the direction perpendicular to the electrostatic dust collector, and the air flow passes through the three components in the order from left to right, i.e., the air first passes through the charged component 1, then passes through the isolation plate 3 and the dust collecting component 2. It can be understood that the isolation plate 3 is arranged in the channel of the dust collecting component 2 to isolate the dust that is originally adsorbed in the channel of the dust collecting component 2. The three components can be stacked in the order of the charged component 1, the isolation plate 3 and the dust collecting component 2, or in the order of the charged component 1, the dust collecting component 2 and the isolation plate. That is, the isolation plate 3 can be located between the charged component 1 and the dust collecting component 2, or the dust collecting component 2 can be located between the charged component 1 and the isolation plate 3.

[0040] The charged component 1 can be connected to a positive direct-current high-voltage power supply to charge the dust particles in the air passing through the charged component 1. The dust collecting component 2 can be connected to a negative direct-current high-voltage power supply or grounded to form a stable electric field in the dust collecting component 2. The dust particles charged by the charged component 1 are adsorbed onto the isolation plate 3 under the action of the electric field when entering the dust collecting component 2.

[0041] The electrostatic dust collector arranged in the above manner can physically isolate the dust particles in the air and the electrode plate 21 of the dust collecting component 2 by the isolation plate 3, which can effectively prevent the dust particles from accumulating on the electrode plate 21 and eliminate the electric spark phenomenon caused by the accumulation of the dust particles on the electrode plate 21. When cleaning the dust on the dust collecting component 2, the dust collecting component 2 does not need to be disassembled, and only the non-powered isolation plate 3 needs to be disassembled. The dust collecting component 2 can be avoided to be arranged in a detachable structure, so as to avoid the problems of corrosion, deformation and sharp tip electric generation of the electrode plate 21 of the dust collecting component 2 caused by water washing.

[0042] Please refer to Figure 3 and Figure 4 The isolation plate 3 includes a panel 31 and a plurality of isolation strips 32 arranged on the panel 31. The splicing position of the panel 31 and the isolation strips 32 is provided with a hollow portion 311.

[0043] It should be noted that in the embodiment, the isolation plate 3 is provided with a planar panel 31 and a plurality of isolation strips 32, the extension direction of the isolation strips 32 is perpendicular to the panel 31, and the position where the panel 31 is spliced with the isolation strips 32 is provided as a hollow 311 to form a plurality of passages for air flowing through the panel 31. By providing the isolation strips 32, the electrode plate 21 of the dust collection assembly 2 can be isolated from the air flowing through the dust collection assembly 2, so as to avoid that the dust particles in the air are adsorbed on the electrode plate 21, and the dust particles in the air are adsorbed on the isolation strips 32. When the dust particles on the isolation strips 32 accumulate to a required cleaning, the isolation plate 3 only needs to be disassembled and cleaned.

[0044] In the above embodiment, the isolation plate 3 can be installed on the dust collection assembly 2 by screws.

[0045] In the above embodiment, the isolation strip 32 includes at least two long strip plates 321, the at least two long strip plates 321 extend in a direction perpendicular to the panel 31, and a first flow guiding gap aligned with the hollow 311 is formed between adjacent two long strip plates 321 in the same isolation strip 32.

[0046] It can be understood that in the embodiment, the isolation strip 32 includes two long strip plates 321, a first flow guiding gap is formed between the two long strip plates 321, and the first flow guiding gap is aligned with the hollow 311 on the panel 31, so that the air passing through the charged assembly 1 passes through the hollow 311 and the first flow guiding gap in sequence, thereby passing through the isolation strip 32. Under the action of the electric field of the electrode plate 21, the charged dust particles are adsorbed on the long strip plate 321, and the dust removal function is realized.

[0047] In the above embodiment, the long strip plate 321 is a rectangular plate with a certain thickness.

[0048] Further, the two ends of the isolation strip 32 are provided with closed plates 322, and the two closed plates 322 and the two long strip plates 321 are sequentially connected end to end to form a closed ring. In some embodiments, the closed ring can be rectangular.

[0049] It should be noted that the closed plates 322 are selectively added at the two ends of the isolation strip 32, and the two closed plates 322 and the two long strip plates 321 are sequentially connected end to end to form a rectangular closed ring shape, so as to concentrate the air flowing through the isolation strip 32 in the closed ring, thereby adsorbing the dust particles in the air flowing through the dust collection assembly 2 on the isolation strip 32.

[0050] In the above embodiment, the first flow guiding gap is provided with a reinforcing plate 323, and the reinforcing plate 323 can be arranged in parallel with the closed plate 322.

[0051] It can be understood that the reinforcing plate 323 can be selectively added between the adjacent long strip plates 321 in the isolation strip 32, which can enhance the structural strength and stability of the long strip plate 321. In the embodiment, the reinforcing plate 323 is parallel to the closing plate 322. In actual application, the reinforcing plate 323 can also form a non-90° angle with the closing plate 322.

[0052] The isolation strip 32 is added between the adjacent electrode plates 21 of the dust collecting assembly 2, which can assist in enhancing the deformation and bending resistance of the electrode plates 21. Especially, the isolation strip 32 is provided with the closing plate 322 to form a closed loop. After the reinforcing plate 323 is added in the isolation strip 32, it plays a role of auxiliary support for the electrode plates 21 of the dust collecting assembly 2. The side flatness of the electrode plates 21 is greatly improved, the distance between each position of the adjacent electrode plates 21 is effectively controlled, the problem of electric spark caused by deformation of the electrode plates 21 due to being too thin is avoided, and the safety of the dust collecting assembly 2 is improved. Therefore, the electrode plates 21 can be designed to be thinner, longer and with smaller spacing, which greatly reduces the production cost, improves the dust collecting efficiency, and reduces the required high-voltage value.

[0053] Please refer to Figure 5 The long strip plate 321 is provided with a dust containing groove 3211 on the side surface facing the first flow gap.

[0054] It should be noted that some dust containing grooves 3211 can be added on the side surface of the long strip plate 321 facing the first flow gap. The bottom surface of the dust containing groove 3211 is lower than the side surface of the long strip plate 321. When the charged dust particles are close to the side surface of the long strip plate 321 of the isolation plate 3 under the action of the strong electric field of the electrode plate 21, the part of the dust particles falling into the dust containing groove 3211 is less likely to move with the continuously flowing air, thereby avoiding the collected dust particles from being raised again to cause secondary pollution under the influence of wind speed.

[0055] The shape of the dust containing groove 3211 can be a rectangular groove, a triangular groove, or a polygonal groove. It can also be a circular groove, a water drop-shaped groove, or a curved profile groove. The shape of the dust containing groove 3211 is not limited. The number and arrangement of the dust containing groove 3211 are also not limited, as long as the above technical effects can be achieved. Moreover, the bottom surface of the dust containing groove 3211 can be designed as an inclined surface or a curved surface structure to match different application scenarios of the electrostatic precipitator.

[0056] In the above embodiment, the dust collecting assembly 2 includes a plurality of electrode plates 21, the plurality of electrode plates 21 are used to form a channel for mounting the isolation plate 3, the plurality of electrode plates 21 extend along a first direction, and the plurality of electrode plates 21 are arranged at intervals in a second direction perpendicular to the first direction. A second flow gap is formed between the adjacent two electrode plates 21.

[0057] It can be understood that a plurality of electrode plates 21 are arranged in the passage of the dust collecting assembly 2, the electrode plates 21 are in the shape of a narrow rectangular cross section or other additional reinforced structures, each electrode plate 21 extends in a first direction, and the plurality of electrode plates 21 are arranged at intervals in a second direction perpendicular to the first direction, a second flow gap is formed between adjacent two electrode plates 21, and the distance between the long strip plates 321 is consistent with the distance between the second flow gaps.

[0058] As a feasible implementation, the electrode plates 21 can be replaced by an electrode net.

[0059] As an implementation, a plurality of isolation strips 32 are arranged at intervals in the vertical direction of the long strip plate 321, the distance between adjacent two isolation strips 32 is greater than the thickness of the electrode plate 21, the distance between adjacent two long strip plates 321 in the same isolation strip 32 is equal to the interval between adjacent two electrode plates 21, and the length of the long strip plate 321 extending in the third direction is greater than the length of the electrode plate 21 extending in the third direction. The third direction can be a direction perpendicular to the panel 31.

[0060] It can be understood that when the isolation plate 3 is arranged on the passage of the dust collecting assembly 2, the electrode plate 21 is arranged between adjacent two isolation strips 32, the long strip plate 321 can be tightly attached to the side surface of the electrode plate 21, and the long strip plate 321 of the two adjacent isolation strips 32 and the panel 31 form a U-shaped structure, which completely wraps and isolates the electrode plate 21 in the air inlet direction. When the air flows through the dust collecting assembly 2, the positively charged dust particles are adsorbed on the surface of the long strip plate 321 of the isolation plate 3 under the action of the strong dust collecting electric field of the electrode plate 21. Due to the isolation effect of the isolation plate 3 on the air, the electrode plate 21 of the dust collecting assembly 2 is not directly in contact with the dust particles in the air, so the electrode plate 21 does not need to be disassembled and cleaned separately in the subsequent cleaning process.

[0061] The isolation plate 3 can be made of insulating materials such as ceramic, polytetrafluoroethylene, polyvinyl chloride, Teflon, etc. It can be integrally formed by injection molding, blow molding, etc., and is simple to process and manufacture.

[0062] In the above case, the dust collecting assembly 2 further comprises an auxiliary frame 22, the auxiliary frame 22 is provided with a negative high-voltage interface 23 or a grounding interface 24, and a plurality of electrode plates 21 are fixed on the auxiliary frame 22. The electrodes of adjacent two electrode plates 21 are opposite, and a plurality of electrode plates 21 with the same electrode are connected to the negative high-voltage interface 23 or the grounding interface 24 in parallel.

[0063] It can be understood that the electrodes of the two adjacent electrode plates 21 are opposite, which can enhance the electric field between the two adjacent electrode plates 21, thereby enhancing the dust collection capacity of the dust collection assembly 2. The multiple electrode plates 21 of the same electrode are connected to the negative high-voltage interface 23 or the ground interface 24 in parallel, respectively. The negative high-voltage interface 23 is connected to the negative direct-current high-voltage power supply, and the ground interface 24 is connected to the ground. The electrode plates 21 form a dust collection electric field between them. The isolation plate 3 is installed in the channel of the dust collection assembly 2, and the panel 31 on the isolation plate 3 is inlaid on the inner side of the auxiliary frame 22 of the dust collection assembly 2 and completely covers the windward opening of the air flow channel of the dust collection assembly 2.

[0064] In the above embodiment, the charging assembly 1 includes a charging frame 11, the charging frame 11 is provided with a positive high-voltage interface 12, and the charging frame 11 is provided with a plurality of electrode filaments 13. The electrode filaments 13 are connected to the positive high-voltage interface 12 in parallel.

[0065] It should be noted that the positive high-voltage interface 12 is connected to the positive direct-current high-voltage power supply, and the electrode filaments 13 are powered by the positive direct-current high-voltage power supply to form a high-voltage electric field, thereby charging the dust particles in the air passing through the charging assembly 1.

[0066] The charging assembly 1 includes a plurality of electrode filaments 13, and the electrode filaments 13 are made of metal wires with high conductivity, such as tungsten wires, copper wires, etc. The electrode filaments 13 can also be designed in a thorn shape to enhance the discharge intensity. The electrode filaments 13 are connected to the positive high-voltage interface 12 in parallel. When the air flows through the electrode filaments 13, it is ionized under the action of the high-voltage electric field to generate positive ions, which combine with dust particles in the air to make the dust particles carry positive charges, providing the possibility for the downstream dust collection assembly 2 to capture dust particles.

[0067] The charging frame 11 is a frame structure made of non-conductive material, used to fix the two ends of the electrode filaments 13 and the positive high-voltage interface 12.

[0068] In summary, the electrostatic dust removal device, when the air containing a large amount of dust particles flows through the electrostatic dust removal device, the air first enters the inside passage of the charging frame 11 of the charging assembly 1, the air flowing into the passage is ionized into a large number of positive ions by the plurality of electrode filaments 13 connected to the positive direct current high voltage arranged in the region, the positive ions collide with the dust particles in the air to be charged, and then the charged dust particles flow into the inside passage of the auxiliary side frame 22 of the dust collecting assembly 2 downstream with the air, the isolation plate 3 covering the windward surface of the inside passage of the dust collecting assembly 2 guides the air to flow into the first flow guiding gap of the isolation strip 32 on the isolation plate 3, and the charged dust particles are affected by the strong dust collecting electric field on the electrode plate 21 in the first flow guiding gap of the isolation strip 32, and will move towards the electrode plate 21, since the isolation strip 32 is arranged between the electrode plate 21 and the flowing air, when the dust particles move to the surface of the isolation strip 32, the movement is stopped and the dust particles are adsorbed on the surface of the isolation strip 32, finally the dust particles in the air are captured, the air passing through the first flow guiding gap of the isolation strip 32 is clean air, since the captured dust particles are isolated from the electrode plate 21 with high voltage by the isolation strip 32, there is no need to worry about the phenomenon of back corona or sparking caused by the accumulation of captured dust particles.

[0069] When the electrostatic dust removal device is operated for a period of time, the captured dust particles need to be cleaned, at this time, the isolation plate 3 can be disassembled from the dust collecting assembly 2, and the isolation plate 3 can be washed with water, since the isolation plate 3 does not need to be connected to any power supply in the working state, the problem of wire connection does not need to be considered during disassembly, and the stable and reliable wire can be directly connected between the dust collecting assembly 2 and the high-voltage power supply, without the need for a detachable snap type connection scheme, so that the risk of electric leakage at the position of the detachable connection structure can be completely avoided. The electrode plate 21 on the dust collecting assembly 2 does not need to be disassembled for cleaning, which avoids the problems of oxidation and corrosion of the electrode plate 21 after water washing, and also avoids the risk of sparking caused by deformation or knocking of the electrode plate 21 caused by repeated disassembly and assembly.

[0070] In addition to the electrostatic dust removal device disclosed in the above embodiments, the utility model also provides an air cleaning device, which comprises an air inlet and an air outlet, and the air outlet is provided with the above-mentioned electrostatic dust removal device, and the structures of other parts of the air cleaning device refer to the prior art, which will not be described herein.
