And S101, acquiring target characteristic parameters in the oil fume purification equipment.

The main components in the oil smoke can comprise tar, water mist, particulate matters, oil drops and part of organic waste gas molecules, and the target characteristic parameters comprise the current concentration of current gas at the gas outlet, the current liquid level of the liquid tank and/or the current processing time of the multi-needle cathode.

Specifically, a sensor may be disposed in the oil fume purification apparatus, and the sensor may be configured to detect a target characteristic parameter of the oil fume purification apparatus, that is, the sensor may detect a current concentration of a current gas at an air outlet of the oil fume purification apparatus, a current liquid level of the liquid tank, and/or a current processing duration of the multi-pin cathode, and send the detected current concentration, current liquid level, and/or current processing duration to the controller. Thus, the controller may receive the current concentration of the gas at the gas outlet, the current level of the tank, and/or the current treatment duration of the multi-pin cathode as detected by the sensor.

In addition, when the controller acquires the target characteristic parameters of the oil fume purification equipment, the target characteristic parameters can be acquired separately or simultaneously, for example, the current concentration of the current gas at the gas outlet can be acquired firstly, then the current liquid level of the liquid tank can be acquired, then the current processing time of the multi-pin cathode can be acquired, the current liquid level of the liquid tank can be acquired firstly, then the current processing time of the multi-pin cathode can be acquired, then the current concentration of the current gas at the gas outlet can be acquired, then the current liquid level of the liquid tank can be acquired, and also the current concentration of the current gas at the gas outlet, the current liquid level of the liquid tank and the current processing time of the multi-pin cathode can be acquired simultaneously. And is not particularly limited herein.

And the controller can acquire the target characteristic parameters of the oil fume purification equipment in real time and can also periodically acquire the target characteristic parameters of the oil fume purification equipment. And is not particularly limited herein.

And S102, determining a target processing strategy matched with the target characteristic parameters.

Specifically, when receiving a target characteristic parameter sent by a sensor, the controller may match the target characteristic parameter with preset reference characteristic information, so as to obtain a target processing strategy matched with the target characteristic parameter; wherein, when the target characteristic parameter includes a current concentration of a current gas at the gas outlet, a current liquid level of the liquid tank, and/or a current processing duration of the multi-pin cathode, the preset reference characteristic information may include a preset reference concentration, a preset reference liquid level, and/or a preset reference processing duration.

Therefore, when the target characteristic parameter includes the current concentration of the current gas at the gas outlet of the lampblack purification device, the step S102 may be implemented by the following sub-steps:

and S1021, matching the current concentration with a preset reference concentration to obtain a first target matching result.

Wherein the preset reference concentration can be used for representing that the concentration of the gas is enough to indicate that the gas is clean gas meeting the emission standard; the preset reference concentration may be a reference concentration threshold or a reference concentration range. And is not limited herein.

Specifically, when the controller obtains the current concentration of the current gas at the gas outlet via the sensor, the controller may further match the current concentration with a preset reference concentration, for example, compare the current concentration with a reference concentration threshold, or compare the current concentration with the maximum value and the minimum value of a reference concentration range, respectively, so as to obtain a first target matching result.

And step S1022, when the first target matching result indicates that the current concentration is higher than the preset reference concentration, determining a target processing strategy comprising increasing the negative high voltage of the high-voltage power supply and the spraying amount of the spray head.

Specifically, when the controller determines that the first target matching result represents that the current concentration of the current gas at the gas outlet is higher than the preset reference concentration, it can be considered that tar, water mist, particulate matters, oil drops and organic waste gas molecules contained in oil smoke entering the oil smoke purifying equipment do not reach the standard and do not meet the emission standard, at the moment, a target processing strategy comprising increasing the negative high voltage of the high-voltage power supply and increasing the spraying amount of the spray head can be determined, so that the smoke entering the oil smoke purifying equipment generates clean gas meeting the emission standard after being purified, and the current concentration of the current gas at the gas outlet higher than the preset reference concentration can comprise that the current concentration is higher than a reference concentration threshold or the current concentration is higher than the maximum value of the reference concentration range.

Specifically, when the controller determines that the first target matching result represents that the current concentration of the current gas at the gas outlet is lower than the preset reference concentration, it can be considered that tar, water mist, particulate matters, oil drops and organic waste gas molecules contained in the oil smoke entering the oil smoke purification equipment are completely treated and meet the emission standard, and at the moment, a target treatment strategy for discharging the target gas generated after the target oil smoke is purified can be determined, so that the clean gas which meets the air emission standard and is generated after the oil smoke is purified is discharged; the current concentration of the current gas at the gas outlet being lower than the preset reference concentration may include the current concentration being less than or equal to a reference concentration threshold, the current concentration being lower than a minimum value of a reference concentration range, or the current concentration being between the minimum value and the maximum value of the reference concentration range.

In the actual processing process, when the target characteristic parameter includes the current liquid level of the liquid tank in the lampblack purification equipment, the step S102 can be realized by the following sub-steps:

and step S11, matching the current liquid level with a preset reference liquid level to obtain a second target matching result.

The preset reference liquid level can be used for representing that the liquid level of the liquid tank is enough to indicate that the content of tar, particulate matters and/or oil drops and other impurities in the liquid tank exceeds the standard and the liquid in the liquid tank is easy to overflow or the purification treatment effect is reduced. And, the preset reference level may be a reference level threshold, or a reference level range. And is not limited herein.

Specifically, when the controller obtains the current liquid level of the liquid tank in the lampblack purification equipment, the current liquid level can be further matched with a preset reference liquid level, for example, the current liquid level is compared with a reference liquid level threshold value, or the current liquid level is respectively compared with the maximum value and the minimum value of a reference liquid level range, so that a second target matching result is obtained. Wherein, the current liquid level of liquid case in the oil smoke clarification plant can acquire via the liquid level detector that sets up in the liquid case.

And step S12, when the second target matching result indicates that the current liquid level is higher than the preset reference liquid level, determining a target processing strategy including executing a target collection operation for the liquid in the liquid tank.

Specifically, when the controller determines that the second target matching result represents that the current liquid level of a liquid tank in the oil fume purification equipment is higher than a preset reference liquid level, it can be considered that tar, water mist, particulate matters, oil drops and organic waste gas molecules in the oil fume are adsorbed by electrons emitted by a multi-needle cathode, and then fall into the liquid tank after being wetted by liquid sprayed by a grid anode, so that the liquid in the liquid tank is about to overflow and the oil fume purification treatment effect is reduced, and at the moment, a target treatment strategy for executing target collection operation on the liquid in the liquid tank can be determined, so that the liquid in the liquid tank can not overflow and the tar, the water mist, the particulate matters, the oil drops and the organic waste gas molecules in the oil fume can be efficiently removed; the current liquid level of a liquid tank in the lampblack purification equipment is higher than the preset reference liquid level, and the current liquid level is higher than the reference liquid level threshold value or is larger than the maximum value of the reference liquid level range.

And step S13, when the second target matching result indicates that the current liquid level is lower than the preset reference liquid level, determining a target processing strategy including continuing to execute target oil smoke purification operation.

Specifically, when the controller determines that the second target matching result represents that the current liquid level of a liquid tank in the oil fume purification equipment is lower than a preset reference liquid level, it can be considered that tar, water mist, particulate matters, oil drops and organic waste gas molecules in the oil fume are adsorbed by electrons emitted by a multi-needle cathode, and then fall into the liquid tank after being wetted by liquid sprayed by a grid anode, so that the liquid in the liquid tank cannot overflow and the oil fume purification treatment effect can be ensured, and at the moment, a target treatment strategy including continuing to execute target oil fume purification operation can be determined, so that the oil fume entering the oil fume purification equipment can be efficiently and quickly treated into clean gas which meets the emission standard and cannot generate secondary pollution; the current liquid level of the liquid tank in the lampblack purification equipment is lower than the preset reference liquid level, and the current liquid level is less than or equal to the reference liquid level threshold value, is lower than the minimum value of the reference liquid level range, or is between the minimum value and the maximum value of the reference liquid level range.

In the actual processing procedure, when the target characteristic parameter includes the current processing duration of the multi-needle cathode in the lampblack purification device, the step S102 can be realized by the following sub-steps:

and step S21, matching the current processing time length with a preset reference processing time length to obtain a third target matching result.

The preset reference processing time length can be used for representing that the multi-needle cathode emits electrons, and the time length of the electrons contacting with tar, water mist, particulate matters, oil drops and organic waste gas molecules in oil smoke is enough to indicate that the surface of the multi-needle cathode is about to coke. The preset reference processing time length may be a reference processing time length threshold or a reference processing time length range. And is not limited herein.

Specifically, when the controller obtains the current processing duration of the multi-needle cathode in the lampblack purification equipment through the sensor, the current processing duration can be further matched with a preset reference processing duration, for example, the current processing duration is compared with a reference processing duration threshold, or the current processing duration is respectively compared with the maximum value and the minimum value of a reference processing duration range, so that a third target matching result is obtained.

And step S22, when the third target matching result represents that the current processing time length reaches the preset reference processing time length, determining a target processing strategy including executing target heating operation of a control heating rod.

Specifically, the controller determines that the third target matching result represents that the current processing duration of the multi-needle cathode in the lampblack purification equipment is longer than the preset reference processing duration, the surface of the multi-needle cathode is considered to be about to coke, and at the moment, a target processing strategy for controlling the heating rod to perform target heating operation can be determined, so that the aim of continuously and efficiently processing lampblack purification operation by the multi-needle cathode is fulfilled; the current processing time length of the multi-needle cathode in the lampblack purification equipment is longer than the preset reference processing time length, and the current processing time length is longer than the reference processing time length threshold value or the current processing time length is longer than the maximum value of the reference processing time length range.

And step S23, when the third target matching result indicates that the current processing time length does not reach the preset reference processing time length, determining a target processing strategy including continuing to execute the target oil smoke purification operation.

Specifically, the controller determines that the third target matching result represents that the current processing time of the multi-needle cathode in the lampblack purification equipment is shorter than the preset reference processing time, the surface of the multi-needle cathode is considered to have no coking trend and lampblack can be continuously processed, and at the moment, a target processing strategy for continuously executing the target lampblack purification operation can be determined, so that the lampblack entering the lampblack purification equipment can be efficiently and quickly processed into clean gas which meets the emission standard and does not generate secondary pollution; the current processing time length of the multi-needle cathode in the lampblack purification equipment is less than the preset reference processing time length, and the current processing time length is less than or equal to the reference processing time length threshold value, is less than the minimum value of the reference processing time length range, or is between the minimum value and the maximum value of the reference processing time length range.

In the actual processing process, when the target characteristic parameters acquired by the controller include the current concentration of the current gas at the gas outlet, the current liquid level of the liquid tank and the current processing duration of the multi-needle cathode, the current concentration and the preset reference concentration may be further matched, the current liquid level and the preset reference liquid level may be further matched, and the current processing duration and the preset reference processing duration may be further matched, so as to obtain a first matching result, a second matching result and a third matching result, thereby determining a target processing strategy corresponding to the first matching result, the second matching result and the third matching result. The specific matching process is as described in the foregoing embodiments, and is not described herein again.

And step S103, controlling to perform target processing according to the target processing strategy.

In the actual processing procedure, the specific implementation procedure of step S103 may include the following sub-steps:

and step S1031, when a target processing strategy comprising increasing the negative high voltage of the high-voltage power supply and the spraying amount of the spray head is determined, controlling to increase the negative high voltage of the high-voltage power supply, increasing the distance between the multi-needle cathode and the grid anode and increasing the spraying amount of the conductive liquid sprayed by the spray head, and obtaining the adjusted information of the first target.

Specifically, when the controller determined the target treatment strategy including the negative high pressure that increases high voltage power supply and the volume of spraying of shower nozzle, can think that the tar that contains in the oil smoke that gets into in the oil smoke clarification plant, water smoke, particulate matter, oil droplet and organic waste gas molecule are not handled up to standard and do not conform to emission standard, the controller can increase high voltage power supply's negative high pressure this moment, increase the interval between many needles negative pole and the grid positive pole and increase shower nozzle and spray the volume that electrically conductive liquid was sprayed, with this realization with flue gas treatment for up to standard gas and can not produce secondary pollution's purpose.

The first target adjusted information may include an adjusted negative high voltage after the negative high voltage of the high voltage power supply is increased, an adjusted gap after the gap between the multi-needle cathode and the grid anode is increased, and an adjusted spraying amount after the spraying amount of the conductive liquid sprayed by the spray head is increased.

And S1032, under the action of the first target adjusted information, controlling to perform target oil smoke purification operation aiming at the oil smoke entering the shell.

Specifically, the controller can control the oil fume purification equipment to perform target oil fume purification operation on the smoke entering the oil fume purification equipment under the action of the first target adjusted information, so that the processed smoke generates a symbol emission standard and does not generate secondary pollution clean gas.

In the actual processing procedure, step S103 can also be realized by the following procedure:

and step S21, when the target processing strategy including the target collection operation of the liquid in the liquid tank is determined, controlling the target collection operation of the target filtering operation of the liquid in the liquid tank and the target impurities generated after the filtering operation to be executed, and obtaining second target adjusted information.

Specifically, when the controller determines that a target processing strategy aiming at the target collection operation of liquid in the liquid tank is executed, the controller can consider that the liquid in the liquid tank is about to overflow and the contents of tar, water mist, particulate matters and oil drops exceed the standard, and at the moment, the controller can control the liquid in the liquid tank to firstly carry out filtering operation and then collect and discharge target impurities generated after the filtering operation, so that the aim of continuously and efficiently executing the flue gas purification operation is fulfilled. The target impurities may include tar, particulate matters, oil droplets, and the like.

Wherein the second target adjusted information can be used to characterize the target impurities generated after the liquid in the liquid tank is filtered and collected.

And step S22, under the action of the second target adjusted information, controlling the target oil smoke purification operation aiming at the oil smoke entering the shell.

Specifically, the controller can control the oil fume purification equipment to continue to perform target oil fume purification operation on the flue gas entering the oil fume purification equipment under the action of the second target adjusted information, so that the treated flue gas generates a symbol emission standard and does not generate secondary pollution clean gas.

and step S31, when the target processing strategy for controlling the heating rod to perform the target heating operation is determined, controlling the heating rod to perform the target heating operation, and obtaining third target adjusted information.

Specifically, when the controller determines that a target treatment strategy including controlling the heating rod to perform a target heating operation is to be executed, the controller may consider that coking is about to occur on the surface of the multi-needle cathode, and at this time, the controller may control the electric heating rod to generate heat, so that the multi-needle cathode generates heat, and the surface of the multi-needle cathode does not become dirty (e.g., tar and the like is not contaminated).

Wherein the third target adjusted information can be used for representing that the heating rod starts to generate heat and the surface of the multi-needle cathode can not become dirty or keep clean.

And step S32, under the action of the third target adjusted information, controlling the target oil smoke purification operation aiming at the oil smoke entering the shell.

Specifically, the controller can control the oil fume purification equipment to continue to perform target oil fume purification operation on the flue gas entering the oil fume purification equipment under the action of the information after the third target adjustment, so that the treated flue gas generates a symbol emission standard and does not generate secondary pollution clean gas.

In the actual processing process, when the controller determines a target processing strategy including the discharge of target gas generated after the target oil fume purification processing, the flue gas entering the oil fume purification equipment can be considered to be processed cleanly, and no secondary pollution is generated, and at the moment, the target gas generated after the target oil fume purification operation can be discharged through the air outlet so as to be conveniently discharged into the air or recycled.

The target gas may include nitric oxide, carbon dioxide, water vapor, and other gases meeting emission standards.
