The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The solid waste combustion treatment method provided by the embodiment of the invention is applied to solid waste combustion treatment equipment, the execution main body of the solid waste combustion treatment method is a controller in the solid waste combustion treatment equipment, as shown in fig. 1, a schematic flow diagram of the solid waste combustion treatment method is shown, and the steps included in the method are specifically described below with reference to fig. 1.

And S101, acquiring target characteristic parameters in the solid waste combustion treatment equipment.

Wherein, the target characteristic parameter includes the current temperature in the furnace body, the first current concentration of organic waste gas molecules in the current gas at the gas outlet, the second current concentration of organic matter impurity in the current gas at the gas outlet, the solid waste combustion treatment equipment can be used for the flue gas that produces after burning solid waste high-efficiently and rapidly to be the clean gas that accords with emission standard, can include carbon monoxide (CO), Hydrocarbon (HC), nitrogen oxide (NOx), oxysulfide (SOx), other organic waste gas molecules and organic matter impurity such as dioxin in the flue gas, the organic matter impurity can include particulate matter, ashes, smoke and dust etc..

Specifically, a sensor may be disposed in the solid waste combustion processing apparatus, and the sensor may be configured to detect a current temperature in a furnace body of the solid waste combustion processing apparatus, a first current concentration of organic waste gas molecules in current gas at the gas outlet, and/or a second current concentration of organic matter impurities in the current gas, and send the detected current temperature, the first current concentration, and/or the second current concentration to the controller. Thus, the controller may receive the current temperature in the furnace detected by the sensor, the current first current concentration of organic waste gas molecules in the gas at the gas outlet, and/or the current second current concentration of organic impurities in the gas.

In addition, the controller can obtain the current temperature in the furnace body, the first current concentration of organic waste gas molecules in the current gas at the gas outlet and the second current concentration of organic impurities in the current gas at the gas outlet independently, or at least two of the current temperatures and the second current concentrations can be obtained simultaneously. And is not particularly limited herein.

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

Specifically, when receiving the target characteristic parameters sent by the sensor, the controller may further match the target characteristic parameters with preset target characteristic information, so as to obtain a target processing strategy matched with the target characteristic parameters; when the target characteristic parameter includes a current temperature in the furnace body, a first current concentration of organic waste gas molecules in current gas at the gas outlet, and/or a second current concentration of organic impurities in current gas at the gas outlet, the preset target characteristic information may include a preset reference temperature, a first preset reference concentration, and/or a second preset reference concentration.

Therefore, when the target characteristic parameter includes the current temperature in the furnace body of the solid waste combustion processing equipment, the step S102 may be implemented by the following sub-steps:

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

The preset reference temperature can be used for representing that the temperature in the furnace body is enough to indicate that the equipment can be normally used for burning solid waste and treating the smoke generated after the solid waste is fully burned to reach the standard. Also, the preset reference temperature may be a reference temperature range, for example, the reference temperature range is 260 ℃ to 500 ℃.

Specifically, when the controller acquires the current temperature in the furnace body through the sensor, the controller may further match the current temperature with a preset reference temperature, for example, compare the current temperature with a minimum value and a maximum value of a reference temperature range, respectively, so as to obtain a first target matching result.

And step S1022, when the first target matching result indicates that the current temperature reaches the preset reference temperature, determining a target processing strategy including turning off a burner and performing microwave pyrolysis.

Specifically, when the controller determines that the first target matching result represents that the current temperature in the furnace body reaches the preset reference temperature, the temperature in the equipment can be considered to be normally used for solid waste combustion and microwave pyrolysis, and at the moment, a target processing strategy including closing a burner and performing microwave pyrolysis can be determined, so that the purpose of efficiently and quickly combusting solid waste on the premise of not damaging the equipment is achieved; the current temperature in the furnace body reaching the preset reference temperature may include the current temperature being between a minimum value and a maximum value of a reference temperature range, for example, the current temperature being between 260 ℃ and 500 ℃.

And S1023, when the first target matching result indicates that the current temperature does not reach the preset reference temperature, determining a target processing strategy including increasing burner flame.

Specifically, when the controller determines that the first target matching result represents that the current temperature in the furnace body does not reach the preset reference temperature, the temperature in the equipment is considered to be too low, the equipment can not be normally used for burning solid waste, and the solid waste can not be fully burned, and at the moment, a target processing strategy including increasing burner flame spraying can be determined, so that the flue gas generated after the solid waste is normally burned and fully burned can be quickly and efficiently processed to reach the standard; wherein the current temperature in the furnace body not reaching the preset reference temperature may include the current temperature being less than a minimum value of the reference temperature range, such as the current temperature being less than 260 ℃.

It should be noted that when the controller determines that the current temperature in the furnace body is higher than the maximum value of the reference temperature range, for example, the current temperature is higher than 500 ℃, and even the equipment may be damaged, it may be considered that the temperature in the equipment is too high, and the equipment may be damaged, and at this time, the controller may control to perform the over-temperature protection or directly turn off the equipment, so as to achieve the purpose of protecting the equipment from being damaged and prolonging the service life of the equipment.

In the actual processing process, when the target characteristic parameter includes a first current concentration of organic waste gas molecules in the current gas at the gas outlet of the solid waste combustion processing equipment, the step S102 may be implemented by the following sub-steps:

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

The first preset reference concentration can be used for representing the concentration of organic waste gas molecules in the gas, which is sufficient to indicate that the gas meets the emission standard and does not produce secondary pollution. The first preset reference concentration may be a first reference concentration threshold, or may be a first reference concentration range. And is not limited herein.

Specifically, when the controller obtains the first current concentration of the organic waste gas molecules in the current gas at the gas outlet via the sensor, the first current concentration may be further matched with a first preset reference concentration, for example, the first current concentration is compared with a first reference concentration threshold, or the first current concentration is respectively compared with a maximum value and a minimum value of a first reference concentration range, so as to obtain a second target matching result.

And step S12, when the second target matching result indicates that the first current concentration is higher than the first preset reference concentration, determining a target processing strategy comprising increasing air pump pressure and increasing microwave power.

Specifically, when the controller determines that the second target matching result represents that the first current concentration of organic waste gas molecules in the current gas at the gas outlet is higher than the first preset reference concentration, the controller may determine that the organic waste gas molecules contained in the flue gas generated after the solid waste combustion are not treated to reach the standard by the equipment, and at this time, may determine a target treatment strategy including increasing the pressure of the air pump and increasing the microwave power, so as to achieve the purpose of treating the flue gas to reach the standard; wherein the first present concentration of organic waste gas molecules in the present gas at the gas outlet being higher than the first preset reference concentration may comprise the first present concentration being greater than a first reference concentration threshold or the first present concentration being greater than a maximum of a first reference concentration range.

Step S13, determining a target treatment strategy including exhausting the current gas when the second target matching result indicates that the first current concentration is lower than the first preset reference concentration.

Specifically, when the controller determines that the second target matching result represents that the first current concentration of organic waste gas molecules in the current gas at the gas outlet is lower than the first preset reference concentration, the solid waste combustion treatment equipment can be considered to treat the organic waste gas molecules contained in the flue gas generated after the solid waste combustion to reach the standard, and at the moment, a target treatment strategy for discharging the current gas can be determined, so that clean gas generated after the solid waste combustion treatment can be timely discharged; wherein the first present concentration of organic waste gas molecules in the present gas at the gas outlet being lower than the first preset reference concentration comprises the first present concentration being less than a first reference concentration threshold, the first present concentration being between a minimum value and a maximum value of a first reference concentration range, or the first present concentration being less than a minimum value of the first reference concentration range.

In the actual processing process, when the target characteristic parameter includes a second current concentration of organic impurities in the current gas at the gas outlet of the solid waste combustion processing equipment, the step S102 may be implemented by the following sub-steps:

and step S21, matching the second current concentration with a second preset reference concentration to obtain a third target matching result.

The second preset reference concentration can be used for representing that the concentration of the organic impurities in the gas is enough to indicate that the gas meets the emission standard and does not generate secondary pollution. The second preset reference concentration may be a second reference concentration threshold, or a second reference concentration range. And is not limited herein.

Specifically, when the controller obtains the second current concentration of the organic impurities in the current gas at the gas outlet of the solid waste combustion processing equipment through the sensor, the second current concentration may be further matched with a second preset reference concentration, for example, the second current concentration is compared with a second reference concentration threshold value or the second current concentration is compared with the maximum value and the minimum value of a second reference concentration range, so as to obtain a third target matching result.

And step S22, when the third target matching result indicates that the second current concentration is higher than the second preset reference concentration, determining a target processing strategy including increasing the voltage of the high-voltage power supply and increasing the microwave power.

Specifically, when the controller determines that the third target matching result represents that the second current concentration of the organic impurities in the current gas at the gas outlet is higher than the second preset reference concentration, the controller may determine that the organic impurities contained in the flue gas generated after the solid waste combustion are not treated to reach the standard by the equipment, and at this time, may determine a target treatment strategy including increasing the voltage of the high-voltage power supply and increasing the microwave power, so as to achieve the purpose of treating the flue gas generated after the solid waste combustion to reach the standard; the second current concentration of the organic impurities in the current gas at the gas outlet being higher than the second preset reference concentration may include that the second current concentration is greater than a second reference concentration threshold or the second current concentration is greater than a maximum value of a second reference concentration range.

Step S23, when the third target matching result indicates that the second current concentration is lower than the second preset reference concentration, determining a target treatment strategy including exhausting the current gas.

Specifically, when the controller determines that the third target matching result represents that the second current concentration of the organic impurities in the current gas at the gas outlet is lower than the second preset reference concentration, the solid waste combustion treatment equipment can be considered to treat the organic impurities in the flue gas generated after the solid waste combustion to reach the standard, and at the moment, a target treatment strategy including the step of discharging the current gas can be determined, so that the clean gas generated after the solid waste combustion treatment can be timely discharged; the second current concentration of the organic impurities in the current gas at the gas outlet being lower than the second preset reference concentration may include that the second current concentration is smaller than a second reference concentration threshold, the second current concentration is between a minimum value and a maximum value of a second reference concentration range, or the second current concentration is smaller than a minimum value of the second reference concentration range.

It should be noted that, when the target characteristic parameters obtained by the controller include at least two of a current temperature in the furnace, a first current concentration of organic waste gas molecules in current gas at the gas outlet, and a second current concentration of organic matter impurities in the current gas, matching the current temperature with a preset reference temperature, matching the first current concentration with a first preset reference concentration, and matching the second current concentration with a second preset reference concentration may be further performed, so as to obtain at least two corresponding target matching results, thereby determining a target processing strategy corresponding to the at least two target matching results. The specific matching process is as described in the foregoing embodiments, and is not described herein again.

And step S103, controlling and executing target processing operation according to the target processing strategy.

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

and step S1031, when a target treatment strategy comprising closing the burner and performing microwave pyrolysis is determined, controlling to close the burner and controlling the solid waste combustion chamber to perform solid waste combustion.

Specifically, when the controller determines the target treatment strategy including closing the burner and performing microwave pyrolysis, the temperature in the furnace body of the equipment can be considered to be normally used for solid waste combustion and microwave pyrolysis, and at the moment, the controller can control to close the burner and control solid waste in the solid waste combustion chamber to perform solid waste combustion under the action of electronic ignition. That is, the furnace body can be used as a combustion furnace.

And S1032, when the accumulated time of the solid waste combustion reaches the preset reference time, acquiring the current oxygen content in the furnace body.

Specifically, when the controller determines that the solid waste in the solid waste combustion chamber starts to combust under the action of electronic ignition, the temperature in the furnace body can be obtained in real time or periodically, and when the accumulated time of solid waste combustion reaches the preset reference time, the temperature in the furnace body can be considered to be increased, and the current oxygen content in the furnace body can be further obtained at the moment so as to provide a basis for subsequently determining whether the microwave pyrolysis is suitable to be carried out in the furnace body.

And step S1033, controlling to close the air blower if the current oxygen content reaches a preset reference oxygen content.

Wherein, the preset reference oxygen content can be used for representing that the oxygen content and the carbon dioxide content in the furnace body are enough to indicate that the furnace body can be used for microwave pyrolysis. The preset reference oxygen content may be a reference oxygen content threshold, or a reference oxygen content range, and is not limited specifically herein.

Specifically, when the controller obtains the current oxygen content in the furnace body, the current oxygen content may be further compared with a preset reference oxygen content, for example, the current oxygen content is compared with a reference oxygen content threshold, or the current oxygen content is respectively compared with a minimum value and a maximum value of a reference oxygen content range, so as to obtain a comparison result.

When the comparison result indicates that the current oxygen content reaches a preset reference oxygen content, for example, the current oxygen content is equal to the reference oxygen content threshold or the current oxygen content is between the minimum value and the maximum value of the reference oxygen content range, it can be considered that carbon dioxide exists in the current furnace body and no oxygen exists in the current furnace body, and at this time, the blower can be controlled to be turned off so as to perform microwave pyrolysis operation; on the contrary, when the comparison result indicates that the current oxygen content does not reach the preset reference oxygen content, for example, the current oxygen content is different from the reference oxygen content threshold value or the current oxygen content is not between the minimum value and the maximum value of the reference oxygen content range, it can be considered that not only carbon dioxide but also oxygen exists in the current furnace body, and at this time, the solid waste can be controlled to continue to combust and the blower is controlled to continue to blow until no oxygen exists.

And S1034, when prompt information representing that the blower is turned off is detected, controlling to execute target microwave pyrolysis operation.

Specifically, when the controller detects the prompt information indicating that the blower is turned off, it may be considered that the temperature and the oxygen content in the oven body may be used for performing microwave pyrolysis, and at this time, the target microwave pyrolysis operation may be controlled to be performed. Namely, the furnace body can be used as a microwave pyrolysis furnace.

It should be noted that, when the controller determines the target treatment strategy including increasing the air pump pressure and increasing the microwave power, it may be considered that the equipment does not treat the organic waste gas molecules contained in the flue gas generated after the solid waste combustion to reach the standard, and at this time, the controller may control to increase the power of the microwave source in the MW-LEP waste gas treatment unit and increase the power of the microwave source at the bottom of the furnace body, so as to obtain the result after the first target adjustment. Then, the controller may further control the target waste gas treatment operation and the target dust removal operation for the solid waste combustion product under the effect of the first target adjusted result. Wherein the first target adjusted result may include a first adjusted power after the power of the microwave source in the MW-LEP exhaust gas treatment unit is increased and a second adjusted power after the power of the microwave source at the bottom of the furnace body is increased, and the solid waste combustion product may include flue gas generated after the solid waste combustion.

In addition, when the controller determines a target treatment strategy comprising increasing the voltage of the high-voltage power supply and increasing the microwave power, the controller can consider that organic impurities contained in the flue gas generated after solid waste combustion are not treated to reach the standard, and at the moment, the controller can control the voltage of the negative high-voltage power supply in the MW-LEP waste gas treatment unit to be increased, the power of the microwave source in the MW-LEP waste gas treatment unit to be increased and the power of the microwave source at the bottom of the furnace body to be increased, so that a second target adjusted result is obtained. Then, the controller can further control the target waste gas treatment operation and the target dust removal operation on the solid waste combustion products under the action of the second target adjusted result. The second target adjusted result may include an adjusted voltage after the voltage of the negative high voltage power supply in the MW-LEP exhaust gas treatment unit is increased, a third adjusted power after the power of the microwave source in the MW-LEP exhaust gas treatment unit is increased, and a fourth adjusted power after the power of the microwave source at the bottom of the furnace body is increased, and the solid waste combustion product may be flue gas generated after solid waste combustion.

When the controller determines a target processing strategy comprising the current gas discharge, the current gas at the gas inlet can be considered to be processed to reach the standard, and the controller can control the current gas to be discharged at the moment, so that the aim of timely discharging the clean gas generated after processing is fulfilled.

That is to say, the invention can realize the purpose of efficiently and rapidly processing the smoke generated by burning the solid waste according to the current temperature in the furnace body, the first current concentration of organic waste gas molecules in the current gas at the gas outlet and the second current concentration of organic matter impurities in the current gas, and solves the problem that the treatment efficiency of the solid waste is not high due to the fact that the household waste needs to be treated by combining photobiology, microwaves and plasmas in the prior art and the control process is not involved, thereby greatly improving the treatment efficiency of the solid waste, reducing the energy consumption and prolonging the service life of the solid waste burning treatment equipment.
