[0001] The utility model belongs to the technical field of oil fume purification equipment, and more specifically, particularly relates to an oil fume purification device with circulating spray cleaning. Background Art

[0002] In the oil fume purification setting, there is an electrostatic oil fume purifier, which usually adopts a plate structure or a cylinder structure. Its working principle is to use a high-voltage electrostatic field to ionize the gas between the electrodes, so that the fine smoke and oil mist colloid particles are charged, so that they can adhere to the electrode plate or electrode cylinder to achieve the purpose of efficient oil fume purification.

[0003] However, after the electrostatic fume purifier has been running for a long time, a large amount of oil stains will often be adsorbed on the electrode plates. When the oil stains reach a certain amount, it will affect the fume purification efficiency of the electrostatic fume purifier. Due to the complex structure of the fume purification device, the disassembly and cleaning of the electrode plates are very inconvenient, which not only requires professional personnel to handle, but also incurs high costs. Therefore, in order to solve this problem, corresponding technical solutions have also been proposed in the prior art. For example, the Chinese utility model patent with application number 202120926820.9 uses a nozzle to spray cleaning liquid to rinse the electrode plate to achieve self-cleaning. However, in order to ensure the adsorption effect of the electrode plate, it needs to be cleaned frequently. Therefore, a large amount of cleaning fluid needs to be used, which will increase the cost of the user and is not conducive to economic and environmental protection.

DETAILED DESCRIPTION

[0026] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0027] The utility model provides a technical solution: a circulating spray cleaning oil fume purification device, such as Figure 1 Figure 2As shown, the device has an air inlet 1 and an air outlet 2, and an electrostatic adsorption structure 3 arranged between the air inlet 1 and the air outlet 2. Since the oil fume is purified by electrostatic adsorption, the adsorbed oil fume will adhere to the electrostatic adsorption structure 3, which will affect the adsorption effect over time. Therefore, a rotary spray structure 4 is arranged above the electrostatic adsorption structure 3, and an oil receiving tank 5 is arranged below it. The rotary spray structure 4 sprays cleaning liquid on the electrostatic adsorption structure 3 regularly or continuously to clean it, so that the electrostatic adsorption structure 3 maintains a high adsorption capacity, and the cleaning liquid involved in cleaning drips into the oil receiving tank 5 below.

[0028] Since frequent cleaning is required to ensure the adsorption effect of the electrostatic adsorption structure 3, a large amount of cleaning liquid will inevitably be used. In order to reduce the use of cleaning liquid, the oil receiving tank 5 is connected to the rotary spray structure 4 through a spray pipe with a purifier 6. The cleaning liquid in the oil receiving tank 5 is filtered and purified by the purifier 6, and the cleaning liquid is provided to the rotary spray structure 4 again for use, so as to achieve recycling and improve economic efficiency. The method provided can use a water pump to suck the cleaning liquid to supply the rotary spray structure 4. The water pump can be set independently or integrated with the rotary spray structure 4.

[0029] The specific structure of the oil fume purification device is introduced in more detail below:

[0030] About electrostatic adsorption structure 3:

[0031] like Figure 3 Figure 4 As shown, the electrostatic adsorption structure 3 includes a plurality of positive plates 31 and negative plates 32, the positive plates 31 and negative plates 32 are arranged at intervals, and the positive plates 31 and negative plates 32 are provided with positive plate vias 34 and negative plate vias 38 on their surfaces, respectively. The plurality of positive plates 31 are connected together through positive electrode rods 33, and the positive electrode rods 33 pass through the negative plate vias 38 in a non-contact manner. The plurality of negative plates 32 are connected together through negative electrode rods 35, and the negative electrode rods 35 pass through the positive plate vias 34 in a non-contact manner. In order to ensure the stability of the structure, a plurality of positive electrode rods 33 and negative electrode rods 35 are provided, and a plurality of corresponding positive plate vias 34 and negative plate vias 38 are also provided, and the plurality of electrode rods are evenly distributed on the corresponding plates, respectively, so that the electrostatic adsorption structure 3 can be more structurally sound.

[0032] During implementation, when the positive electrode rod 33 and the negative electrode rod 35 are connected to a power source, the positive plate 31 and the negative plate 32 are charged respectively through the conduction of the two sets of electrode rods, so that an electrostatic field is generated between the two adjacent plates, and the electrostatic field is used to absorb the smoke.

[0033] In order to enhance the adsorption effect of oil smoke, an ionization slot 321 is opened on the surface of the negative plate 32, and anti-electric teeth are arranged on the edge of the ionization slot 321 and the negative plate 32, so as to adapt to the uniform distribution of the electrostatic field and effectively adsorb the oil smoke.

[0034] In terms of installation, insulating plates 36 are provided at both ends of the positive electrode rod 33 and the negative electrode rod 35, and insulating columns 37 are provided on the insulating plates 36. Both ends of the positive electrode rod 33 and the negative electrode rod 35 are respectively installed on the insulating columns 37. This design can effectively prevent the electrostatic adsorption structure 3 from transferring electricity to the mounting structure, and prevent the mounting structure from participating in the adsorption of oil smoke. At the same time, it can also ensure the safety of the equipment and avoid electric shock.

[0035] About the rotary spray structure 4:

[0036] like Figure 5 As shown, the rotary spray structure 4 includes a motor 41, and the motor 41 is installed through a mounting block 46. The motor 41 is connected to a strip nozzle pipe 43 through a through-shaft tee 42, and its connection point is located in the middle of the nozzle pipe 43, and the through-shaft tee 42 is connected to a pipeline of a cleaning liquid. A fan-shaped nozzle 44 is provided at both ends and both sides of the nozzle pipe 43, and the four adjacent fan-shaped nozzles 44 are spaced at the same distance, so that uniform spraying can be ensured. When in use, the fan-shaped nozzle 44 forms a spray surface 45 downward to spray the electrostatic adsorption structure 3, and the motor 41 drives the nozzle pipe 43 to rotate, so that the spray surface 45 continuously sweeps the electrostatic adsorption structure 3, thereby improving the cleaning effect.

[0037] In order to further improve the sweeping spraying effect of the rotary spraying structure 4, as Figure 6 As shown, it is designed as follows: the spraying surface 45 formed by the fan-shaped spray heads 44 at both ends of the spray head pipe 43 is parallel to the end face of the spray head pipe 43. At the same time, the spraying surface 45 formed by the fan-shaped spray heads 44 at both sides of the spray head pipe 43 forms a 45° angle with the side face of the spray head pipe 43. The spraying surfaces 45 formed by the fan-shaped spray heads 44 at both sides of the spray head pipe 43 form a 90° angle with each other. In this way, the four fan-shaped spray heads 44 correspond to multiple angles respectively, so that the coverage of the spray is more uniform.

[0038] In the above structure, if Figure 2As shown, the electrostatic adsorption structure 3 can be set to multiple groups, and the multiple groups of electrostatic adsorption structures 3 are arranged and distributed in sequence along the path from the air inlet 1 to the air outlet 2. The rotary spray structure 4 can also be set to at least two groups, and the at least two groups of rotary spray structures 4 are arranged at intervals along the arrangement direction of the multiple groups of electrostatic adsorption structures 3, so that the spray range formed by them covers all the multiple groups of electrostatic adsorption structures 3. In this way, a smoke purification device with power matching can be designed corresponding to the amount of oil smoke that needs to be adsorbed. At the same time, the number of rotary spray structures 4 is designed according to the number of electrostatic adsorption structures 3, so that a balance is achieved between oil fume purification and cleaning. While ensuring the adsorption of oil smoke, it is completely covered and cleaned.

[0039] About the overall structure of the smoke purification device:

[0040] like Figure 1 Figure 2 As shown, the overall structure is mainly a mounting box 7, an electric control device 12 is arranged on the side of the mounting box 7, and the electrostatic adsorption structure 3 and the rotary spray structure 4 are located in the mounting box 7, and the air inlet 1 and the air outlet 2 are respectively located at both ends of the mounting box 7 to achieve corresponding left and right air inlet and outlet. A mounting frame 8 is arranged below the mounting box 7, and a mounting track 9 is arranged in the mounting frame 8. The oil receiving tank 5 is slidably mounted on the mounting track 9, so that the oil receiving tank 5 can be opened or removed by pulling a card.

[0041] The oil receiving tank 5 is fixed by a limit rod 10, and the two ends of the limit rod 10 are detachably fixed to the mounting frame 8 by buckles 11. In this way, the oil receiving tank 5 is held by the limit rod 10 to prevent it from moving. When disassembly is required, the limit rod 10 is removed by opening the buckles 11 at both ends, so that the oil receiving tank 5 can resume movement.

[0042] like Figure 7 As shown, in order to facilitate the filtration of the cleaning liquid, the purifier 6 is installed in the oil receiving tank 5, and the bottom of the oil receiving tank 5 is an inclined surface, and the purifier 6 is located at the lowest point of the inclined surface. This can make the design structure more compact while ensuring that the purifier 6 can purify and filter the cleaning liquid in the oil receiving tank 5.
