Description

Technical Field

[0001] The present application relates to the field of waste gas treatment technology, and in particular to a multi-channel dioxin treatment method and device in a hazardous waste treatment process. Background Art

[0002] Dioxins are a class of highly toxic persistent organic pollutants that are usually produced by incomplete combustion of chlorine-containing substances during the high-temperature incineration of hazardous solid waste.

[0003] In the relevant technology, due to the high toxicity, persistence, bioaccumulation and long-distance migration ability of dioxins, the flue gas generated by the high-temperature incineration of hazardous solid waste usually needs to be treated. High-temperature combustion is the most commonly used method. Liquefied natural gas is used to generate a high-temperature flame of at least 850 degrees Celsius in the secondary combustion chamber, and the flue gas is then passed into the secondary combustion chamber. The high temperature of not less than 850 degrees Celsius destroys the molecular structure of dioxins in the flue gas, thereby destroying the toxicity of dioxins.

[0004] Regarding the above-mentioned related technologies, the use of high-temperature combustion methods to remove dioxins in flue gas requires, on the one hand, equipment that can withstand high-temperature combustion. These equipment need to be made of special materials to ensure that the equipment can operate under extreme conditions without being damaged; on the other hand, a large amount of liquefied natural gas is consumed to ensure that the temperature is within the temperature range of thermal degradation. Special materials and a large amount of liquefied natural gas lead to high costs for dioxin degradation, and there is still room for improvement. Summary of the invention

[0005] In order to reduce the cost of dioxin degradation, the present application provides a multi-channel dioxin treatment method and device in the process of hazardous waste treatment.

[0013] By adopting the above technical scheme, the channel start-up quantity information for degrading dioxins in the current flue gas is output according to the matching of gas flow information and flow quantity relationship, and then the start-up of the high-voltage pulse corona channel is controlled according to the channel start-up quantity information, and the corresponding high-voltage pulse corona channel is specifically controlled to degrade the dioxins according to the dioxin parameter information, thereby realizing low-temperature degradation of dioxins without the need for equipment made of special materials and the large amount of natural gas consumed by the high-temperature degradation chamber, thereby reducing the cost of dioxin degradation.

[0014] Optionally, the step of controlling the high-voltage pulse corona channel to degrade dioxins according to the dioxin parameter information includes:

[0015] Analyze and determine dioxin concentration information and gas flow rate information based on dioxin parameter information;

[0016] Determining basic high-voltage electric pulse electric field parameter information according to dioxin concentration information and preset concentration electric field parameter relationship information;

[0017] Determine the degradation flow rate range information according to the dioxin concentration information and the preset concentration-flow rate relationship information;

[0018] Determine whether the gas flow rate information meets the requirements of the degradation flow rate range information;

[0019] If it is in compliance, the high-voltage pulse corona channel is controlled according to the basic high-voltage electric pulse electric field parameter information to bombard the molecular structure of dioxin to decompose the toxic components;

[0020] If it does not meet the requirements, the high-voltage pulse corona channel is controlled to degrade dioxins according to the gas flow rate information and the basic high-voltage electric pulse electric field parameter information.

[0021] By adopting the above technical scheme, the basic high-voltage electric pulse electric field parameter information of dioxins in the channel is matched and output according to the dioxin concentration information and the concentration electric field parameter relationship information, and then it is determined whether the gas flow rate needs to be adjusted according to the comparison between the gas flow rate information and the degradation flow rate range information. When it is not necessary, the high-voltage pulse corona channel is directly controlled to bombard the molecular structure of dioxins according to the basic high-voltage electric pulse electric field parameter information. When it is necessary, the high-voltage pulse corona channel is controlled to degrade dioxins according to the gas flow rate information and the basic high-voltage electric pulse electric field parameter information, thereby ensuring that the high-voltage pulse corona channel can effectively degrade dioxins of different concentrations and flow rates.

[0022] Optionally, the step of controlling the high-voltage pulse corona channel to degrade dioxins according to the gas flow rate information and the basic high-voltage electric pulse electric field parameter information includes:

[0023] Analyze and determine the flow rate difference information based on the gas flow rate information and the degradation flow rate range information;

[0024] Determine whether the flow rate difference information meets the requirements of the preset positive trigger information;

[0025] If it does not meet the requirements, the high-voltage pulse corona channel is controlled according to the preset speed-up method to degrade the dioxins;

[0026] If yes, then determine whether the gas flow rate information meets the requirements of the preset maximum flow rate information;

[0027] If it does not meet the requirements, the high-voltage pulse corona channel is controlled according to the preset speed reduction method to degrade the dioxins;

[0028] If it is in accordance with the flow velocity difference information and the preset flow velocity electric field parameter relationship information, the electric field parameter information is increased;

[0029] The high-voltage pulse corona channel is controlled according to the enhanced electric field parameter information and the basic high-voltage electric pulse electric field parameter information to degrade dioxins.

[0030] By adopting the above technical solution, the difference between the gas flow rate information and the degradation flow rate range information is calculated to obtain the flow rate difference information. When the flow rate difference information is not a positive value, the high-voltage pulse corona channel is controlled to degrade the dioxins according to the speed-up method. When the flow rate difference information is a positive value and is greater than the maximum flow rate information, the high-voltage pulse corona channel is controlled to degrade the dioxins according to the preset speed-down method, thereby preventing the dioxins from being discharged before the high-voltage pulse corona channel has completely degraded the dioxins due to the flow rate of the dioxins being too fast or too slow, thereby improving the degradation effect of the dioxins.

[0031] Optionally, the step of controlling the high-voltage pulse corona channel to degrade dioxins according to a preset speed reduction method includes:

[0032] Determine the speed reduction adjustment power information according to the flow rate difference information and the preset flow rate power relationship information;

[0033] Obtain the first speed reduction channel sequence number information of the high-voltage pulse corona channel;

[0035] By adopting the above technical scheme, the speed reduction adjustment power information for reducing the dioxin flow rate to within the normal processing range is output according to the flow rate difference information and the flow rate power relationship information, and then the corresponding deceleration fan is controlled according to the first speed reduction channel sequence number information to blow the flue gas with the speed reduction adjustment power information, thereby reducing the speed of dioxins in the high-voltage pulse corona channel, ensuring that there is enough time to degrade the dioxins, and thereby improving the degradation effect of the dioxins.

[0036] Optionally, the step of controlling the high-voltage pulse corona channel to degrade dioxins according to a preset speed reduction method includes:

[0037] Determining adjustment quantity information according to flow rate difference information and preset flow rate quantity relationship information;

[0038] Obtain the second speed reduction channel sequence number information of the high-voltage pulse corona channel;

[0039] According to the second deceleration channel sequence number information, adjustment quantity information and preset deceleration trigger information, the preset damping strips are controlled to decelerate the flue gas, and according to the basic high-voltage electric pulse electric field parameter information, the high-voltage pulse corona channel is controlled to degrade dioxins.

[0040] By adopting the above technical scheme, the adjustment quantity information for reducing the dioxin flow rate to within the normal processing range is output according to the flow rate difference information and the flow rate quantity relationship information, and then the corresponding damping strip is controlled according to the second speed reduction channel sequence number information and the speed reduction trigger information to adjust the quantity information to be flattened, thereby slowing down the speed of smoke entering the channel, thereby reducing the speed of dioxins in the high-voltage pulse corona channel, ensuring that there is enough time to degrade the dioxins, and thereby improving the degradation effect of the dioxins.

[0041] Optionally, the step of controlling the high-voltage pulse corona channel to degrade dioxins according to a preset speed-up method includes:

[0042] Determine whether the gas flow rate information meets the requirements of the preset minimum flow rate information;

[0043] If it does not meet the requirements, the preset speed-up device will be controlled to assist the high-voltage pulse corona channel to degrade the dioxins;

[0044] If it is in accordance with the flow velocity difference information and the preset flow velocity electric field parameter relationship information, the electric field parameter reduction information is determined;

[0045] The high-voltage pulse corona channel is controlled to degrade dioxins according to the reduced electric field parameter information and the basic high-voltage electric pulse electric field parameter information.

[0046] By adopting the above technical solution, when the gas flow rate information is less than the minimum flow rate information, it indicates that the flow rate of dioxins is too slow, resulting in that after the channel completes the degradation of dioxins, the subsequent dioxins cannot enter the channel in time to complete the degradation. Therefore, the speed-up device is controlled to increase the flow rate of the flue gas, thereby assisting the high-voltage pulse corona channel to degrade the dioxins, thereby improving the degradation efficiency of dioxins.

[0047] Optionally, the step of controlling a preset speed-up device to assist the high-voltage pulse corona channel in degrading dioxins includes:

[0048] Determine the speed-up adjustment power information according to the flow rate difference information and the preset flow rate power relationship information;

[0049] Obtain the first speed-up channel sequence number information of the high-voltage pulse corona channel;

[0050] According to the first speed-up channel sequence number information and the speed-up adjustment power information, the preset speed-up fan is controlled to speed up the flue gas, and according to the basic high-voltage electric pulse electric field parameter information, the high-voltage pulse corona channel is controlled to degrade dioxins.

[0051] By adopting the above technical scheme, the speed-up regulating power information for increasing the flow rate of dioxins to within the normal processing speed range is output according to the flow rate difference information and the flow rate-power relationship information, and then the corresponding speed-up fan is controlled according to the first speed-up channel sequence number information to blow the flue gas with the speed-up regulating power information, thereby increasing the flow rate of dioxins, so that after the high-voltage pulse corona channel degrades the dioxins, the subsequent dioxins can enter the channel in time for degradation, thereby improving the degradation efficiency of dioxins.

[0052] Optionally, the step of controlling a preset speed-up device to assist the high-voltage pulse corona channel in degrading dioxins includes:

[0053] Analyze and determine velocity ratio information based on gas flow rate information and degradation flow rate range information;

[0054] Analyze and determine the adjusted cross-sectional area information according to the speed ratio information and the preset channel cross-sectional area information;

[0055] Obtain the second speed-up channel sequence number information of the high-voltage pulse corona channel;

[0056] According to the second acceleration channel serial number information and the cross-sectional area adjustment information, the preset partition assembly is controlled to adjust the cross-sectional area of ​​the high-voltage pulse corona channel to accelerate the flue gas, and according to the basic high-voltage electric pulse electric field parameter information, the high-voltage pulse corona channel is controlled to degrade dioxins.

[0057] By adopting the above technical scheme, the speed ratio information is obtained by taking the quotient of the gas flow rate information and the degradation flow rate range information, and then the adjusted cross-sectional area information after adjustment is calculated according to the channel cross-sectional area information and the speed ratio information, so as to control the corresponding partition assembly according to the second speed-up channel sequence number information to adjust the cross-sectional area of ​​the channel to the area corresponding to the adjusted cross-sectional area information, so that the speed of dioxins in the channel is increased, and after the dioxins are degraded in the high-voltage pulse corona channel, the subsequent dioxins can enter the channel in time for degradation, thereby improving the degradation efficiency of dioxins.

[0058] In the second aspect, the present application provides a multi-channel dioxin treatment device in a hazardous waste treatment process, which adopts the following technical solution:

[0059] A multi-channel dioxin treatment device in a hazardous waste treatment process, comprising:

[0060] A degradation chamber, wherein two corresponding sides of the degradation chamber are respectively provided with an air inlet for smoke to enter the degradation chamber and an air outlet for smoke to flow out of the degradation chamber;

[0061] A high-voltage pulse corona channel, wherein the high-voltage pulse corona channel is arranged in the degradation chamber, one end of the high-voltage pulse corona channel is connected to the air inlet, the other end of the high-voltage pulse corona channel is connected to the air outlet, and a plurality of high-voltage pulse corona channels are evenly arranged;

[0062] A speed-up device, which is arranged in the degradation chamber and is used to increase the speed of the smoke passing through the high-voltage pulse corona channel;

[0063] A deceleration device, which is arranged in the degradation chamber and is used to reduce the speed of smoke passing through the high-voltage pulse corona channel;

[0064] An acquisition module, wherein the acquisition module acquires parameters related to flue gas;

[0065] The processing terminal is respectively connected with the high-voltage pulse corona channel, the speed-up device, the speed-down device and the acquisition module data to perform data interaction.

[0066] By adopting the above technical solution, after the flue gas enters the degradation chamber, the acquisition module obtains the flue gas related parameters and sends them to the processing terminal. After the processing terminal analyzes and processes the data, it controls the high-voltage pulse corona channel to open with the corresponding parameters, and controls the speed-up device and the speed-down device to assist the high-voltage pulse corona channel to bombard the molecular structure of dioxins, thereby completing the low-temperature reduction of dioxins, reducing energy consumption without the need for special materials and equipment, and thereby reducing the degradation cost of dioxins.

[0067] Optionally, a side of the degradation chamber corresponding to the entrance of the high-voltage pulse corona channel gradually tilts away from the air inlet toward the direction close to the high-voltage pulse corona channel, and a side of the degradation chamber corresponding to the exit of the high-voltage pulse corona channel gradually tilts away from the air inlet toward the direction close to the high-voltage pulse corona channel.

[0068] By adopting the above technical scheme, when the smoke enters the degradation chamber through the air inlet, the inclined side wall of the degradation chamber drives the smoke into the high-voltage pulse power supply channel for degradation. When the smoke is degraded and comes out of the channel, the inclined side wall of the degradation chamber drives the smoke to be discharged from the air outlet, thereby improving the convenience of smoke circulation.

[0069] In summary, the present application includes at least one of the following beneficial technical effects:

[0070] By matching and outputting the channel start-up quantity information for degrading dioxins in the current flue gas according to the gas flow information and the flow quantity relationship, and then controlling the start-up of the high-voltage pulse corona channel according to the channel start-up quantity information, and specifically controlling the corresponding high-voltage pulse corona channel to degrade the dioxins according to the dioxin parameter information, low-temperature degradation of dioxins is achieved without the need for equipment made of special materials and a large amount of natural gas, thereby reducing the cost of dioxin degradation;

[0071] The flow rate difference information is obtained by calculating the difference between the gas flow rate information and the degradation flow rate range information. When the flow rate difference information is not a positive value, the high-voltage pulse corona channel is controlled to degrade the dioxin according to the speed-up method. When the flow rate difference information is a positive value and is greater than the maximum flow rate information, the high-voltage pulse corona channel is controlled to degrade the dioxin according to the preset speed-down method, thereby preventing the high-voltage pulse corona channel from discharging the dioxin before the dioxin is completely degraded due to the flow rate of the dioxin being too fast or too slow, thereby improving the degradation effect of the dioxin.

[0072] When the gas flow rate information is less than the minimum flow rate information, it indicates that the flow rate of dioxins is too slow, resulting in the failure of subsequent dioxins to enter the channel in time to complete the degradation after the channel completes the degradation of dioxins. Therefore, the speed-up device is controlled to increase the flow rate of the flue gas, thereby assisting the high-voltage pulse corona channel to degrade dioxins, thereby improving the degradation efficiency of dioxins.

[0083] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 9 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0084] The embodiment of the present application discloses a multi-channel treatment method for dioxins in a hazardous waste treatment process, and specifically discloses a treatment terminal 6, an acquisition module 5 and a high-voltage pulse corona channel 2. The treatment terminal 6 is respectively connected to the acquisition module 5 and the high-voltage pulse corona channel 2 through data wires to realize data interaction and control. When the acquisition module 5 obtains that the flue gas enters the degradation chamber 1, the entry trigger information is sent to the treatment terminal 6. In response to the entry trigger information, the treatment terminal 6 issues an instruction to control the acquisition module 5 to obtain the gas flow information of the flue gas and provide feedback. The treatment terminal 6 outputs the channel start-up quantity information of the opening channel according to the feedback gas flow information and the flow quantity relationship information. After the treatment terminal 6 opens the high-voltage pulse corona channel 2 according to the quantity corresponding to the channel start-up quantity information, it controls the acquisition module 5 to detect the dioxin parameter information in the high-voltage pulse corona channel 2, thereby controlling the high-voltage pulse corona channel 2 to degrade the dioxins according to the dioxin parameter information. While achieving the degradation of dioxins, no temperature-resistant equipment made of special materials is required, and the energy consumption is greatly reduced, thereby reducing the cost of dioxin degradation.

[0085] Reference Figure 1 The present application discloses a multi-channel dioxin treatment method in a hazardous waste treatment process, comprising the following steps:

[0086] Step S100: obtaining preset smoke entry trigger information.

[0087] The flue gas refers to the flue gas containing dioxins generated after the high-temperature combustion of hazardous solid waste. The entry trigger information refers to the trigger data of the flue gas entering the degradation chamber 1 from the air inlet 11 of the degradation chamber 1. When the photoelectric sensor in the acquisition module 5 senses that the flue gas has entered, the entry trigger information is sent to the processing terminal 6.

[0088] Step S101: acquiring flue gas flow information based on entry trigger information.

[0089] After receiving the entry trigger information, the processing terminal 6 responds to the trigger data corresponding to the entry trigger information, thereby issuing an instruction to control the acquisition module 5 to detect the gas flow information of the flue gas, providing data support for the subsequent degradation of dioxins.

[0090] The gas flow information refers to the flow of the flue gas entering the degradation chamber 1 , which is detected by the thermal flow meter in the acquisition module 5 and sent to the processing terminal 6 .

[0091] Step S102: determining channel activation quantity information according to the gas flow information and preset flow quantity relationship information.

[0092] Among them, the flow quantity relationship information refers to the correspondence between the gas flow and the number of channels. The larger the gas flow, the more channels are needed to degrade dioxins in the flue gas. The correspondence between the gas flow and the number of channels is determined by the operator based on the flue gas that can be processed by the actual channel, and then the operator stores the two in the database after one-to-one correspondence.

[0093] The channel start-up quantity information refers to the number of opened high-voltage pulse corona channels 2, which is obtained by matching the flow input corresponding to the gas flow information into the database corresponding to the flow quantity relationship information by the processing terminal 6 and outputting it.

[0094] Step S103 : controlling the preset high-voltage pulse corona channel 2 to start according to the channel start-up quantity information, and obtaining the dioxin parameter information in the high-voltage pulse corona channel 2 .

[0095] Among them, after the processing terminal 6 determines the channel startup quantity information, the processing terminal 6 controls the cover covering the channel entrance to open according to the number corresponding to the channel startup quantity information, thereby controlling the corresponding number of high-voltage pulse corona channels 2 to start in preparation for the subsequent degradation of dioxins, and controls the acquisition module 5 to detect the dioxin parameter information in the high-voltage pulse corona channel 2, providing data support for the subsequent control of the discharge of the high-voltage pulse corona channel 2.

[0096] High-voltage pulse corona channel 2 refers to a special conductive channel formed by high-voltage pulse discharge technology. When a high-voltage pulse is applied between electrodes, if the electric field strength is large enough, a corona discharge phenomenon will be generated in the gas near the electrodes. The high-energy electrons, free radicals and other active substances generated by the corona discharge can destroy the molecular structure of dioxins, achieving the effect of degrading dioxins. Dioxin parameter information refers to the flow rate and concentration of dioxins entering the high-voltage pulse corona channel 2. The flow rate can be detected by thermal sensing, and the concentration can be detected by portable GC-MS / MS.

[0097] Step S104: controlling the high-voltage pulse corona channel 2 to degrade dioxins according to the dioxin parameter information.

[0098] Among them, after the processing terminal 6 opens the high-voltage pulse corona channel 2 and obtains the dioxin parameter information in the high-voltage pulse corona channel 2, the processing terminal 6 controls the high-voltage pulse corona channel 2 to degrade the dioxin, thereby achieving low-temperature degradation of the dioxin. The specific method is referred to Figure 2 steps.

[0099] Reference Figure 2 The steps of controlling the high-voltage pulse corona channel 2 to degrade dioxins according to the dioxin parameter information include:

[0100] Step S200: Analyze and determine dioxin concentration information and gas flow rate information according to the dioxin parameter information.

[0101] The dioxin concentration information refers to the concentration of dioxins entering the high-voltage pulse corona channel 2 , and the gas flow rate information refers to the flow rate of dioxins in the high-voltage pulse corona channel 2 , which are obtained by the processing terminal 6 identifying and calling the parameters corresponding to the dioxin parameter information.

[0102] Step S201: determining basic high-voltage electric pulse electric field parameter information according to dioxin concentration information and preset concentration electric field parameter relationship information.

[0103] Among them, the concentration-electric field parameter relationship information refers to the corresponding relationship between the dioxin concentration and the electric field parameters. The electric field parameters include voltage and frequency. The dioxin concentration is proportional to the voltage and frequency, that is, the higher the dioxin concentration, the greater the voltage and frequency, thereby ensuring that the high-energy electrons, free radicals and other active substances generated by corona discharge are more active to bombard more dioxins. The operator changes the electric field parameters in actual operation. When the degradation rate of dioxins reaches more than 90%, the electric field parameters at this time are defined as the electric field parameters of the dioxin concentration, and the two are stored in the database after corresponding.

[0104] The basic high-voltage electric pulse electric field parameter information refers to the voltage and frequency parameters of the electric field for treating the current concentration of dioxins at normal flow rate, which is obtained by matching the concentration corresponding to the dioxin concentration information into the database corresponding to the concentration electric field parameter relationship information by the processing terminal 6.

[0105] Step S202: Determine the degradation flow rate range information according to the dioxin concentration information and the preset concentration-flow rate relationship information.

[0106] Among them, the concentration-flow rate relationship information refers to the corresponding relationship between dioxin and the flow rate range. The concentration is inversely proportional to the flow rate, that is, the higher the concentration, the lower the flow rate. After the operator determines the electric field parameters, the dioxin of that concentration is degraded using the electric field parameters and the flow rate is continuously adjusted to determine the two flow rate endpoint values ​​with a degradation rate above 90%. After that, the range is determined as the degradation flow rate range of the dioxin of that concentration. The two are matched one by one by the operator and stored in the database.

[0107] The degradation flow rate range information refers to the flow rate range for normal degradation of dioxins at the current concentration. The processing terminal 6 inputs the concentration corresponding to the dioxin concentration information into the database corresponding to the concentration-flow rate relationship information for matching and output.

[0108] Step S203: Determine whether the gas flow rate information meets the requirements of the degradation flow rate range information.

[0109] The requirement of the degradation flow rate range information refers to being within the flow rate range corresponding to the degradation flow rate range information. The processing terminal 6 determines whether the flow rate corresponding to the gas flow rate information is within the flow rate range corresponding to the degradation flow rate range information, thereby determining whether the flow rate of dioxin is too fast or too slow, and providing data support for the subsequent control of the high-voltage pulse corona channel 2 to degrade dioxin.

[0110] Step S2031: If it is in compliance, the high-voltage pulse corona channel 2 is controlled to bombard the molecular structure of dioxin to decompose the toxic components according to the basic high-voltage electric pulse electric field parameter information.

[0111] Among them, if the processing terminal 6 determines that the flow rate corresponding to the gas flow rate information is within the flow rate range corresponding to the degradation flow rate range information, it indicates that the flow rate of dioxin in the channel is within the flow rate range of high degradation rate. Therefore, the high-voltage pulse corona channel 2 can be directly controlled to discharge according to the voltage and frequency corresponding to the basic high-voltage electric pulse electric field parameter information, so that the high-energy electrons, free radicals and other active substances generated by the corona discharge bombard the molecular structure of dioxin, thereby decomposing the toxic components and completing the low-temperature degradation of dioxin.

[0112] Step S2032: If not, the high-voltage pulse corona channel 2 is controlled to degrade dioxins according to the gas flow rate information and the basic high-voltage electric pulse electric field parameter information.

[0113] Among them, if the processing terminal 6 determines that the flow rate corresponding to the gas flow rate information is not within the flow rate range corresponding to the degradation flow rate range information, it means that the flow rate of dioxin in the channel exceeds the flow rate range of high degradation rate. Therefore, the basic high-voltage electric pulse electric field parameter information cannot be used to directly control the high-voltage pulse corona channel 2 to degrade dioxin, and the gas flow rate information or the basic high-voltage electric pulse electric field parameter information needs to be adjusted before degradation can be performed. The specific method is referred to Figure 3 steps.

[0114] Reference Figure 3 The steps of controlling the high-voltage pulse corona channel 2 to degrade dioxins according to the gas flow rate information and the basic high-voltage electric pulse electric field parameter information include:

[0115] Step S300: analyzing and determining flow rate difference information based on the gas flow rate information and the degradation flow rate range information.

[0116] Among them, the flow rate difference information refers to the difference between the flow rate corresponding to the gas flow rate information and the endpoint value corresponding to the degradation flow rate range information. The processing terminal 6 first compares the gas flow rate information and the degradation flow rate range information. When the gas flow rate information is greater than the degradation flow rate range information, the difference between the maximum value of the gas flow rate information and the degradation flow rate range information is calculated; when the gas flow rate information is less than the degradation flow rate range information, the difference between the minimum value of the gas flow rate information and the degradation flow rate range information is calculated.

[0117] Step S301: Determine whether the flow rate difference information meets the requirement of preset positive trigger information.

[0118] The positive trigger information refers to trigger data with a positive velocity difference, and the requirement for the positive trigger information refers to a positive value corresponding to the positive trigger information, both of which are stored in the processing terminal 6 by the operator.

[0119] The processing terminal 6 determines whether the difference corresponding to the flow rate difference information is a positive value corresponding to the positive trigger information, thereby determining whether the flow rate of dioxin is too fast or too slow, providing data support for subsequent control of the high-voltage pulse corona channel 2.

[0120] Step S3011: If not, the high-voltage pulse corona channel 2 is controlled to degrade dioxins according to a preset speed-up method.

[0121] Among them, if the processing terminal 6 determines that the difference corresponding to the flow rate difference information is not the positive value corresponding to the positive trigger information, it means that the gas flow rate is less than the minimum degradation flow rate, so the gas flow rate is slow, and the high-voltage pulse power supply channel is controlled according to the speed-up method to degrade dioxins.

[0122] The speed-up method refers to the degradation method of dioxins by the high-voltage pulse corona channel 2 when the flow rate of dioxins is slow, which is stored in the processing terminal 6 by the operator. Figure 6 steps.

[0123] Step S3012: If yes, determine whether the gas flow rate information meets the requirement of the preset maximum flow rate information.

[0124] Among them, the maximum flow rate information refers to the maximum gas flow rate allowed within the adjustable range of the electric field, which is determined by the operator based on the actual situation of the high-voltage pulse corona channel 2. The requirement for the maximum flow rate information refers to a flow rate not greater than that corresponding to the maximum flow rate information.

[0125] If the processing terminal 6 determines that the difference corresponding to the flow rate difference information is a positive value corresponding to the positive trigger information, it indicates that the gas flow rate is greater than the maximum value of the degradation flow rate range, and therefore the gas flow rate is faster, and thus continues to determine whether the flow rate corresponding to the gas flow rate information is not greater than the flow rate corresponding to the maximum flow rate information, providing data support for subsequent determination of degradation by changing the electric field or by changing the flow rate.

[0126] Step S30121: If not, the high-voltage pulse corona channel 2 is controlled to degrade dioxins according to a preset speed reduction method.

[0127] Among them, if the processing terminal 6 determines that the flow rate corresponding to the gas flow rate information is greater than the flow rate corresponding to the maximum flow rate information, it means that the gas flow rate is too fast. Even if the electric field parameters are increased, it cannot be guaranteed that the degradation rate of dioxins will be maintained above 90%. Therefore, the high-voltage pulse corona channel 2 is controlled according to the speed reduction method to degrade dioxins.

[0128] The speed reduction method refers to a method of reducing the flow rate of dioxins and causing the high-voltage pulse corona channel 2 to degrade dioxins. The method is stored in the processing terminal 6 by the operator. For specific methods, refer to Figure 4 and Figure 5 steps.

[0129] Step S30122: If it is in compliance, the electric field parameter information is determined to be improved according to the flow velocity difference information and the preset flow velocity electric field parameter relationship information.

[0130] Among them, if the processing terminal 6 determines that the flow rate corresponding to the gas flow rate information is not greater than the flow rate corresponding to the maximum flow rate information, it means that although the flow rate of dioxin is faster, the degradation rate of dioxin can still be maintained above 90% by improving the electric field parameters. Therefore, the electric field parameter information is determined based on the flow rate difference information and the flow rate electric field parameter relationship information to provide data support for the subsequent control of the high-voltage pulse corona channel 2.

[0131] The flow velocity electric field parameter relationship information refers to the correspondence between the flow velocity difference and the improved electric field parameter. When the flow velocity difference is a positive value, the flow velocity difference is proportional to the improved electric field parameter, that is, the larger the flow velocity difference, the larger the improved electric field parameter; when the flow velocity difference is a negative value, the flow velocity difference is inversely proportional to the adjusted electric field parameter, that is, the smaller the flow velocity difference, the larger the adjusted electric field parameter. In the actual processing process, the operator increases or decreases the electric field parameter from low to high for different flow velocity differences until the degradation rate reaches 90%, and determines that the increased electric field parameter at this time is the improved electric field parameter corresponding to the flow velocity difference. The operator stores the two in the database after one-to-one correspondence. The improved electric field parameter information refers to the electric field parameter that needs to be increased to keep the dioxin degradation rate of the current flow velocity above 90%. The processing terminal 6 inputs the flow velocity difference corresponding to the flow velocity difference information into the database corresponding to the flow velocity electric field parameter relationship information to match and output.

[0132] Step S301221: controlling the high-voltage pulse corona channel 2 to degrade dioxins according to the enhanced electric field parameter information and the basic high-voltage electric pulse electric field parameter information.

[0133] Among them, after the processing terminal 6 determines the enhanced electric field parameter information, the final electric field parameters are obtained by summing the enhanced electric field parameter information and the basic high-voltage electric pulse electric field parameter information, and then the high-voltage pulse corona channel 2 is controlled to discharge at a voltage and frequency corresponding to the final electric field parameters, so that the high-energy electrons, free radicals and other active substances generated by the corona discharge bombard the molecular structure of dioxins, thereby decomposing the toxic components and completing the low-temperature degradation of dioxins.

[0134] Reference Figure 4 The steps of controlling the high-voltage pulse corona channel 2 to degrade dioxins according to a preset speed reduction method include:

[0135] Step S400: Determine the speed reduction adjustment power information according to the flow rate difference information and the preset flow rate power relationship information.

[0136] Among them, the flow rate power relationship information refers to the corresponding relationship between the flow rate difference and the adjusted power. When the flow rate difference is positive, the flow rate difference is proportional to the adjusted power; when the flow rate difference is negative, the flow rate difference is inversely proportional to the adjusted power. When determining different flow rate differences, the operator adjusts the blowing power from small to large, and determines that the power when the flow rate difference is zero is the adjusted power. The operator matches the two one by one and stores them in the database.

[0137] The speed reduction adjustment power information refers to the power for reducing the gas flow rate to a degradation flow rate range, and the processing terminal 6 inputs the flow rate difference corresponding to the flow rate difference information into the database corresponding to the flow rate power relationship information to match and output.

[0138] Step S401: obtaining the first deceleration channel sequence number information of the high-voltage pulse corona channel 2.

[0139] The first speed reduction channel number information refers to the channel number of the channel that needs to reduce the gas flow rate, which is obtained by identifying the number of the acquisition module 5 when the processing terminal 6 determines that the gas flow rate exceeds the maximum gas flow rate.

[0140] Step S402: controlling the preset deceleration fan 41 to decelerate the flue gas according to the first deceleration channel sequence number information and the deceleration adjustment power information, and controlling the high-voltage pulse corona channel 2 to degrade dioxins according to the basic high-voltage electric pulse electric field parameter information.

[0141] Among them, after the processing terminal 6 obtains the speed reduction adjustment power information and the first speed reduction channel sequence number information, the processing terminal 6 controls the corresponding deceleration fan 41 according to the sequence number corresponding to the first speed reduction channel sequence number information to blow and decelerate the flue gas with the power corresponding to the speed reduction adjustment power information, so that the flow rate of dioxins is maintained within the degradation flow rate range, and synchronously controls the high-voltage pulse corona channel 2 to discharge with the voltage and frequency corresponding to the basic high-voltage electric pulse electric field parameter information, so that the high-energy electrons, free radicals and other active substances generated by the corona discharge bombard the molecular structure of dioxins within a sufficient time, thereby decomposing the toxic components and completing the low-temperature degradation of dioxins.

[0142] The deceleration fan 41 refers to a fan installed at the outlet of the high-voltage pulse corona channel 2 , and reduces the flow rate of the gas when the fan blows air into the high-voltage pulse corona channel 2 .

[0143] Reference Figure 5 The steps of controlling the high-voltage pulse corona channel 2 to degrade dioxins according to a preset speed reduction method include:

[0144] Step S500: determining adjustment quantity information according to flow rate difference information and preset flow rate quantity relationship information.

[0145] Among them, the flow rate quantity relationship information refers to the corresponding relationship between the flow rate difference and the adjustment quantity. The flow rate difference is proportional to the adjustment quantity, that is, the larger the flow rate difference, the larger the adjustment quantity. The operator determines the flow rate that a single damping strip 42 can reduce in actual processing, and then determines the quantity based on the flow rate difference and the quotient of the single reduced flow rate. The operator stores the two in a database after one-to-one correspondence.

[0146] The adjustment quantity information refers to the number of damping strips 42 started when the flow velocity is reduced, and is obtained by matching and outputting the flow velocity difference corresponding to the flow velocity difference information input by the processing terminal 6 into the database corresponding to the flow velocity quantity relationship information.

[0147] Step S501: obtaining the second deceleration channel sequence number information of the high-voltage pulse corona channel 2.

[0148] The second speed reduction channel sequence number information in this step is consistent with the first speed reduction channel sequence number information in step S401, and will not be described in detail here.

[0149] Step S502: according to the second deceleration channel sequence number information, the adjustment quantity information and the preset deceleration trigger information, the preset damping strip 42 is controlled to be spread out to decelerate the flue gas, and according to the basic high-voltage electric pulse electric field parameter information, the high-voltage pulse corona channel 2 is controlled to degrade dioxins.

[0150] Among them, after the processing terminal 6 obtains the second deceleration channel sequence number information, the processing terminal 6 controls the damping strip 42 to be laid flat in the deceleration posture corresponding to the deceleration trigger information according to the sequence number corresponding to the second deceleration channel sequence number information and the quantity corresponding to the adjustment quantity information, so that the damping strip 42 decelerates the flue gas when the flue gas enters the channel, and synchronously controls the high-voltage pulse corona channel 2 to discharge with the voltage and frequency corresponding to the basic high-voltage electric pulse electric field parameter information, so that the high-energy electrons, free radicals and other active substances generated by the corona discharge bombard the molecular structure of dioxins in a sufficient time, thereby decomposing the toxic components and completing the low-temperature degradation of dioxins.

[0151] The damping strip 42 refers to a device for degrading the gas flow rate. The damping strip 42 is installed at the entrance of the high-voltage pulse corona channel 2. The damping strip 42 is controlled by a rotating cylinder to realize two states, vertical and flat, so as to reduce the gas flow rate.

[0152] Reference Figure 6 The steps of controlling the high-voltage pulse corona channel 2 to degrade dioxins according to the preset speed-up method include:

[0153] Step S600: Determine whether the gas flow rate information meets the requirements of the preset minimum flow rate information.

[0154] Among them, the minimum flow rate information refers to the minimum flow rate that can keep the dioxin degradation rate above 90% after adjusting the electric field parameters. The specific value is determined by the operator according to the specific situation of the high-voltage pulse corona channel 2. The requirement for the minimum flow rate information refers to a flow rate not less than that corresponding to the minimum flow rate information.

[0155] The processing terminal 6 determines whether the flow rate corresponding to the gas flow rate information is not less than the flow rate corresponding to the minimum flow rate information, thereby providing data support for the subsequent degradation of dioxins by adjusting the electric field parameters or adjusting the flow rate and controlling the high-voltage pulse corona channel 2.

[0156] Step S601: If not, the preset speed-up device 3 is controlled to assist the high-voltage pulse corona channel 2 in degrading dioxins.

[0157] If the processing terminal 6 determines that the flow rate corresponding to the gas flow rate information is less than the flow rate corresponding to the minimum flow rate information, it indicates that the flow rate of dioxin is too slow. After the high-voltage pulse corona channel 2 completes the degradation of dioxin, the subsequent flue gas cannot enter the high-voltage pulse corona channel 2 in time. Therefore, the speed-up device 3 is controlled to assist the high-voltage pulse corona channel 2 in degrading dioxin. The specific method is referred to Figure 7 and Figure 8 steps.

[0158] The speed-increasing device 3 refers to a device for increasing the flow rate of dioxins in the channel, and a speed-increasing fan 31 or a partition assembly 32 can be used to adjust the cross-sectional area of ​​the channel.

[0159] Step S602: If it is in compliance, the electric field parameter reduction information is determined based on the flow velocity difference information and the preset flow velocity electric field parameter relationship information.

[0160] Among them, if the processing terminal 6 determines that the flow rate corresponding to the gas flow rate information is not less than the flow rate corresponding to the minimum flow rate information, it indicates that the flow rate of dioxin is slow, and the parameters corresponding to the basic high-voltage electric pulse electric field parameter information are too high, resulting in energy waste. Therefore, the processing terminal 6 inputs the flow rate difference corresponding to the flow rate difference information into the database corresponding to the flow rate electric field parameter relationship information, matches and outputs the reduced electric field parameter information, and provides data support for the subsequent control of the high-voltage pulse corona channel 2.

[0161] The velocity electric field parameter relationship information in this step is consistent with the velocity electric field parameter relationship information in step S30122, and will not be repeated here. Reducing the electric field parameter information refers to the parameter value that needs to be reduced when the basic high-voltage electric pulse electric field parameter information degrades the dioxin at this flow rate without causing energy waste, and the processing terminal 6 inputs the velocity difference corresponding to the velocity difference information into the database corresponding to the velocity electric field parameter relationship information to match and output.

[0162] Step S6021: controlling the high-voltage pulse corona channel 2 to degrade dioxins according to the reduced electric field parameter information and the basic high-voltage electric pulse electric field parameter information.

[0163] Among them, after the processing terminal 6 determines the reduced electric field parameter information, it calculates the difference between the electric field parameters corresponding to the basic high-voltage electric pulse electric field parameter information and the battery parameters corresponding to the reduced electric field parameter information to obtain the final electric field parameters, and then controls the high-voltage pulse corona channel 2 to discharge at the voltage and frequency corresponding to the final electric field parameters, so that the high-energy electrons, free radicals and other active substances generated by the corona discharge bombard the molecular structure of dioxins at an appropriate activity level, thereby decomposing the toxic components and completing the low-temperature degradation of dioxins.

[0164] Reference Figure 7 The steps of controlling the preset speed-up device 3 to assist the high-voltage pulse corona channel 2 in degrading dioxins include:

[0165] Step S700: Determine speed-up adjustment power information according to flow rate difference information and preset flow rate-power relationship information.

[0166] The flow rate power relationship information in this step is consistent with the flow rate power relationship information in step S400, and will not be described in detail here. The speed-up adjustment power information refers to the power required to increase the dioxin flow rate to the degradation flow rate range, and the processing terminal 6 inputs the flow rate difference corresponding to the flow rate difference information into the database corresponding to the flow rate power relationship information to match and output.

[0167] Step S701: Obtain the first speed-up channel sequence number information of the high-voltage pulse corona channel 2.

[0168] Among them, the first speed-up channel serial number information refers to the channel serial number that needs to be accelerated in the high-voltage pulse corona channel 2, which is obtained by identifying the serial number of the acquisition module 5 when the processing terminal 6 determines that the gas flow rate is less than the minimum gas flow rate.

[0169] Step S702: controlling the preset speed-up fan 31 to speed up the flue gas according to the first speed-up channel sequence number information and the speed-up adjustment power information, and controlling the high-voltage pulse corona channel 2 to degrade dioxins according to the basic high-voltage electric pulse electric field parameter information.

[0170] Among them, after the processing terminal 6 determines the first speed-up channel sequence number information and the speed-up adjustment power information, it controls the corresponding speed-up fan 31 according to the sequence number corresponding to the first speed-up channel sequence number information to blow air to the flue gas with the power corresponding to the speed-up adjustment power information, thereby increasing the flow rate of dioxins to within the degradation flow rate range, and synchronously controls the high-voltage pulse corona channel 2 to discharge with the voltage and frequency corresponding to the basic high-voltage electric pulse electric field parameter information, so that the high-energy electrons, free radicals and other active substances generated by the corona discharge bombard the molecular structure of dioxins at an appropriate activity level, thereby decomposing the toxic components and completing the low-temperature degradation of dioxins.

[0171] The speed-up fan 31 refers to a fan used to increase the gas flow rate in the high-voltage pulse corona channel 2. The speed-up fan 31 is installed at the entrance of the high-voltage pulse corona channel 2, so as to blow air into the high-voltage pulse corona channel 2 to increase the gas flow rate.

[0172] Reference Figure 8 The steps of controlling the preset speed-up device 3 to assist the high-voltage pulse corona channel 2 in degrading dioxins include:

[0173] Step S800: Analyze and determine velocity ratio information based on the gas flow rate information and the degradation flow rate range information.

[0174] The speed ratio information refers to the ratio between the flow rate corresponding to the gas flow rate information and the intermediate value corresponding to the degradation flow rate range information, which is obtained by calculating the quotient of the flow rate corresponding to the gas flow rate information and the intermediate value corresponding to the degradation flow rate range information by the processing terminal 6 .

[0175] Step S801: analyzing and determining the adjusted cross-sectional area information according to the speed ratio information and the preset channel cross-sectional area information.

[0176] The channel cross-sectional area information refers to the cross-sectional area of ​​the high-voltage pulse corona channel 2, which is stored by the operator in the processing terminal 6. Adjusting the cross-sectional area information refers to the specific area value to which the channel cross-sectional area needs to be adjusted when the gas flow rate is increased to within the degradation flow rate range, which is obtained by calculating the product between the ratio corresponding to the speed ratio information and the area value corresponding to the channel cross-sectional area information by the processing terminal 6. When the flow rate is constant, reducing the cross-sectional area of ​​the channel will increase the corresponding flow rate, thereby increasing the flow rate of dioxins.

[0177] Step S802: Obtain the second speed-up channel sequence number information of the high-voltage pulse corona channel 2.

[0178] The second speed-up channel sequence number information in this step is consistent with the first speed-up channel sequence number information in step S701, and will not be described in detail here.

[0179] Step S803: According to the second acceleration channel sequence number information and the cross-sectional area adjustment information, the preset partition assembly 32 is controlled to adjust the cross-sectional area of ​​the high-voltage pulse corona channel 2 to accelerate the flue gas, and according to the basic high-voltage electric pulse electric field parameter information, the high-voltage pulse corona channel 2 is controlled to degrade dioxins.

[0180] Among them, after the processing terminal 6 determines the second speed-up channel serial number information and the adjustment cross-sectional area information, the processing terminal 6 controls the corresponding partition assembly 32 according to the serial number corresponding to the second speed-up channel serial number information to adjust the cross-sectional area of ​​the high-voltage pulse corona channel 2 by adjusting the area corresponding to the cross-sectional area information, so that the gas with a constant flow rate is increased to within the degradation flow rate range when passing through the high-voltage pulse corona channel 2 with a reduced cross-sectional area, and the high-voltage pulse corona channel 2 is synchronously controlled to discharge with the voltage and frequency corresponding to the basic high-voltage electric pulse electric field parameter information, so that the high-energy electrons, free radicals and other active substances generated by the corona discharge bombard the molecular structure of dioxins at an appropriate activity level, thereby decomposing the toxic components and completing the low-temperature degradation of dioxins.

[0181] The partition assembly 32 refers to a device for adjusting the cross-sectional area of ​​the high-voltage pulse corona channel 2. The partition assembly 32 includes a partition and a telescopic rod. The partition is installed on the inner wall of the channel. The telescopic rod controls the movement of the partition to change the cross-sectional area of ​​the channel.

[0182] Reference Fig. 9 Based on the same inventive concept, the embodiment of the present application provides a multi-channel dioxin treatment device in the process of hazardous waste treatment, including a degradation chamber 1 and a high-voltage pulse corona channel 2. The degradation chamber 1 is provided with an air inlet 11 for flue gas to enter the degradation chamber 1 and an air outlet 12 for flue gas after degradation to be discharged from the degradation chamber 1 on the corresponding two sides. The high-voltage pulse corona channel 2 is installed in the degradation chamber 1, and the inlet of the high-voltage pulse corona channel 2 is connected to the air inlet 11, and the outlet of the high-voltage pulse corona channel 2 is connected to the air outlet 12. After the flue gas enters the degradation chamber 1 from the air inlet 11, it enters through the inlet of the high-voltage pulse corona channel 2 and is degraded, and then is discharged from the high-voltage pulse corona channel 2 through the outlet and discharged from the degradation chamber 1 through the air outlet 12. The high-voltage pulse corona channels 2 are evenly installed side by side. In this application, four are taken as an example, so that some space is reserved between the entrance of the high-voltage pulse corona channel 2 and the air inlet 11, and between the exit of the high-voltage pulse corona channel 2 and the air outlet 12, so as to facilitate the distribution of smoke to each high-voltage pulse corona channel 2, and to facilitate the collection and discharge of smoke degraded in each high-voltage pulse corona channel 2 from the degradation chamber 1. One side of the degradation chamber 1 corresponding to the entrance of the high-voltage pulse corona channel 2 is gradually inclined in the direction away from the air inlet 11 to the direction close to the high-voltage pulse corona channel 2, so that when the smoke enters the degradation chamber 1 through the air inlet 11, the inclined side wall drives the smoke into the high-voltage pulse corona channel 2. One side of the degradation chamber 1 corresponding to the exit of the high-voltage pulse corona channel 2 is inclined in the direction away from the air outlet 12 and gradually close to the high-voltage pulse corona channel 2, so that after the smoke leaves the high-voltage pulse corona channel 2, the inclined side wall drives the smoke to leave the degradation chamber 1 from the air outlet 12.

[0183] Reference Fig. 9 , and also includes a speed-up device 3, which is used to increase the speed of the flue gas passing through the high-voltage pulse corona channel 2.

The speed-up fan 31 is installed on the side wall of the degradation chamber 1 corresponding to the entrance of the high-voltage pulse corona channel 2. The speed-up fan 31 corresponds to the high-voltage pulse corona channel 2 one by one. After the speed-up fan 31 is started, it blows air toward the entrance of the high-voltage pulse corona channel 2, thereby increasing the flow rate of the flue gas in the high-voltage pulse corona channel 2. The partition assembly 32 includes a partition, a telescopic rod and a cover cloth. The partition and the telescopic rod are installed on the side wall of the high-voltage pulse corona channel 2. The telescopic rod drives the partition to move in the high-voltage pulse corona channel 2, thereby changing the cross-sectional area of ​​the high-voltage pulse corona channel 2. When the flow rate is constant, the flow rate can be changed by changing the cross-sectional area. The cover cloth is installed between the partition and the side wall of the high-voltage pulse corona channel 2, thereby sealing the gap between the partition and the side wall of the high-voltage pulse corona channel 2. The cover cloth can be made of rubber.

[0184] Reference Fig. 9, also includes a deceleration device 4, which is used to reduce the speed of flue gas passing through the high-voltage pulse corona channel 2. The deceleration device 4 includes a deceleration fan 41 and a damping strip 42. The deceleration fan 41 is installed on the side wall of the degradation chamber 1 corresponding to the outlet of the high-voltage pulse corona channel 2. The deceleration fan 41 corresponds to the high-voltage pulse corona channel 2 one by one. After the deceleration fan 41 is started, it blows air at the outlet of the high-voltage pulse corona channel 2, thereby reducing the flow rate of flue gas in the high-voltage pulse corona channel 2. The damping strip 42 is installed on the partition at the entrance of the high-voltage pulse corona channel 2. The damping strip 42 is controlled by a rotating cylinder to switch between two states of vertical and flat. In the flat state, the damping strip 42 covers part of the entrance of the high-voltage pulse corona channel 2, thereby reducing the flow rate of flue gas entering the high-voltage pulse corona channel 2. There are multiple damping strips 42 evenly arranged, and the specific number is determined by the operator according to actual conditions.
