[0022] The utility model embodiment provides a kind of oil fume waste gas purification equipment, as shown in Figure 1 And Figure 2 It comprises:

[0023] Shell, wind channel is arranged in the shell;The one end of the wind channel is air inlet 1, and the other end is air outlet 2;Gradient electric field field1, gradient electric field field2 and gradient electric field field3 are arranged in the wind channel, and the gradient electric field field1, gradient electric field field2 and gradient electric field field3 are sequentially arranged in the direction of the air inlet 1 towards air outlet 2.

[0024] Here, each gradient electric field is provided with an anode and a cathode, and the voltage between the anode and the cathode can be set according to actual conditions, so that an electric field can be generated between the anode and the cathode. In practice, a direct current power supply can be provided in the oil fume exhaust purification device, and the direct current power supply provides voltage for the anode and the cathode.

[0025] In the oil fume exhaust treatment device, a high voltage is generated by a high-voltage generator (for example, a direct current power supply, etc.), and a strong electric field is formed between two electrodes. The design form of the electrode is various. When the oil fume exhaust enters the electric field area, the oil fume particles will be polarized under the action of the electric field. For linear electrodes, an uneven electric field will be formed around them, and the oil fume particles will move towards the electrodes. For plate electrodes, the oil fume particles will move to the surface of the electrode plate under the action of the electric field force. In the electric field, the oil fume particles collide with gas molecules and acquire electric charges, becoming charged particles. These charged oil fume particles will move to the surface of the electrode with opposite charges under the action of the electric field force.

[0026] In this embodiment, the gradient electric field field i One or more combinations of line-to-line discharge, line-to-plate discharge, tooth-to-tooth discharge, and tooth-to-plate discharge are adopted, where i is a natural number, 1≤i≤3.

[0027] In this embodiment, the gradient electric field field i A metal circular tube and a discharge tip in the metal circular tube are included, where i is a natural number, 1≤i≤3. Here, the tip discharge occurs between the metal circular tube and the discharge tip, thereby forming an electric field.

[0028] In this embodiment, the electric field strength of the gradient electric field field1 is less than the electric field strength of the gradient electric field field2, and the electric field strength of the gradient electric field field2 is less than or equal to the electric field strength of the gradient electric field field3.

[0029] Case 1: When the adsorption capacity of the gradient electric field field1 = the adsorption capacity of the gradient electric field field2 = the adsorption capacity of the gradient electric field field3, the oil fume exhaust gas will first pass through the gradient electric field field1, at this time, the gradient electric field field1 will adsorb a lot of oil fume particles, the concentration of the oil fume particles from the gradient electric field field1 will be reduced, and then the oil fume exhaust gas will pass through the gradient electric field field2 and the gradient electric field field3 in turn. That is, the oil fume particles adsorbed by the gradient electric field field1 > the oil fume particles adsorbed by the gradient electric field field2 > the oil fume particles adsorbed by the gradient electric field field3, so after a long period of use, the oil fume particles on the gradient electric field field1 first reach saturation (at this time, the oil fume exhaust gas purification device needs to be cleaned), but the oil fume particles on the other gradient electric fields are far from saturation, especially the gradient electric field field3. In summary, the time interval for cleaning the oil fume exhaust gas purification device in the scenario shown in case 1 is short.

[0030] Case 2: In the oil fume exhaust gas purification device of the embodiment of the utility model, since the electric field strength of the gradient electric field field1 < the electric field strength of the gradient electric field field2 = the electric field strength of the gradient electric field field3, that is, the adsorption capacity of the gradient electric field field1 < the adsorption capacity of the gradient electric field field2 = the adsorption capacity of the gradient electric field field3. Therefore, during use, the oil fume exhaust gas will pass through the gradient electric field field1, the gradient electric field field2 and the gradient electric field field3 in turn. It can be understood that the adsorption capacity of the gradient electric field field1, the gradient electric field field2 and the gradient electric field field3 is weak, so the concentration of the oil fume particles from the gradient electric field field1 will be high. Since the adsorption capacity of the gradient electric field field2 is strong, the difference between the oil fume particles adsorbed by the gradient electric field field2 and the oil fume particles adsorbed by the gradient electric field field1 will be small, that is, compared with case 1, the difference between the oil fume particles adsorbed by the gradient electric field field1, the oil fume particles adsorbed by the gradient electric field field2 and the oil fume particles adsorbed by the gradient electric field field3 in case 2 will be small, that is, the gradient electric field field1, the gradient electric field field2 and the gradient electric field field3 need to be cleaned at about the same time. In summary, the time interval for cleaning the oil fume exhaust gas purification device in the scenario shown in case 2 is long.

[0031] In summary, the oil fume exhaust gas purification device in the embodiment of the utility model avoids that the oil fume particles are collected in the electric field close to the air inlet 1, and makes the collected oil fume particles as evenly distributed as possible among all the electric fields, thereby greatly prolonging the time interval for cleaning the oil fume exhaust gas purification device.

[0032] In this embodiment, it also includes 3 power supplies, each of which powers a unique gradient electric field, and each of which is detachably connected between the unique gradient electric fields. Since the voltage of each power supply can be different, the connection relationship between the power supply and the gradient electric field can be changed, and thus the voltage of the gradient electric field can be changed.

[0033] In this embodiment, as shown in Figure 3 It also includes a door body 3 for opening and closing the air duct, and when the door body 3 is closed, the door body 3 constitutes the side of the air duct. The 3 power supplies are installed in the door body 3.

[0034] In this embodiment, part of the gradient electric field is connected to a constant current power supply, and the other part of the gradient electric field is connected to a constant voltage power supply.

[0035] In this embodiment, the power supply connected to the gradient electric field field1 is a constant current power supply, and the power supplies connected to the gradient electric field field2 and the gradient electric field field3 are constant voltage power supplies.

[0036] In this embodiment, the air duct is divided into 3 installation positions, and the 3 installation positions are distributed along the extension direction of the air duct. The 3 installation positions correspond one-to-one to the three gradient electric fields. The gradient electric field field1, the gradient electric field field2 and the gradient electric field field3 are detachably installed in the corresponding installation positions.

[0037] In this embodiment, the gradient electric field field1, the gradient electric field field2 and the gradient electric field field3 each include a plurality of positive plates and a plurality of negative plates. In each gradient electric field, the plurality of positive plates and the plurality of negative plates are staggered and arranged in a row, and all the positive plates and all the negative plates are arranged in parallel. Here, the positive plates and the negative plates are staggered and arranged in a row, and all the positive plates and all the negative plates are arranged in parallel, and there is a gap between adjacent positive and negative electrodes. In the row, of the two adjacent plates, one is a positive plate and the other is a negative plate, and the positive and negative plates are arranged in parallel and have a gap therebetween, so that the wind can flow into the gap from the first side and flow out from the second side, or flow into the gap from the second side and flow out from the first side, and the connection direction of the first and second sides is horizontal. Thus, when installing and exchanging the gradient electric field, it is not necessary to distinguish whether the wind flows in from the first side or from the second side.

[0038] Here, the gradient electric field field1, the gradient electric field field2 and the gradient electric field field3 are symmetrical, that is, the air inlet 1 and the air outlet 2 are symmetrical, and can be replaced, when the air inlet and outlet of the oil fume exhaust purification equipment are replaced, the electric field is replaced, only the electric field sequence needs to be replaced, the electric field itself does not need to be rotated and the like, only the connection relationship between the power supply and the gradient electric field needs to be changed.

[0039] It should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.

[0040] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the utility model, and they are not used to limit the protection scope of the utility model, and equivalent embodiments or changes made without departing from the spirit of the utility model art should be included in the protection scope of the utility model.
