[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The present invention proposes a control method for an organic waste gas recovery device, which is used to control an organic waste gas recovery device. Figure 1 The organic waste gas recovery device includes an intake pipe 1, a pressure regulating system 2, a condensation recovery component 3 and an exhaust pipe 4. The pressure regulating system 2 is arranged on the intake pipe 1, and the condensation recovery component 3 connects the pressure regulating system 2 and the exhaust pipe 4. It can be understood that in this embodiment, the condensation recovery component 3 collects organic waste gas by condensation.

[0048] A control method for an organic waste gas recovery device proposed in this application is provided in Figure 2 , including the following steps:

[0049] S101: Acquire first concentration data and second concentration data, where the first concentration data and the second concentration data are concentration data of exhaust gas particles in the intake pipe and the exhaust pipe, respectively.

[0050] In the process of general industrial production, the pressure of exhaust gas when it is discharged is different due to different production equipment. Therefore, when there are exhaust gas particles in the exhaust gas, the pressure of the exhaust gas changes, which will inevitably lead to a change in the concentration of exhaust gas particles per unit volume of the exhaust gas. Therefore, in order to measure the collection rate of exhaust gas before and after collection, the concentration data of exhaust gas particles in the intake pipe and the exhaust pipe can be directly obtained through the sensor, that is, the first concentration data and the second concentration data.

[0051] S102: Acquire a first pressure value in the intake pipe, and determine a target particle collection rate based on the first pressure value, the first concentration data, and the second concentration data.

[0052] It is understandable that in order to avoid the influence of the pressure in the air intake pipe on the final collection rate result, the pressure in the air intake pipe, that is, the pressure in the pipe when the device is just discharged, is also obtained in this step. The target particle collection rate is determined by the first pressure value, the first concentration data and the second concentration data. It is understandable that in this embodiment, the target particle collection rate is also the collection rate that needs to be adjusted later. The target collection rate is also the yield that needs to be adjusted to meet the collection conditions.

[0053] First, the current particle collection rate can be determined based on the first pressure value, the first concentration data and the second concentration data. It can be understood that the current particle collection rate is the ratio between the number of particles before the exhaust gas treatment and the number of particles collected after the exhaust gas treatment.

[0054] Specifically, in this embodiment, since the pressure in the pipeline changes after discharge, the first concentration data and the second concentration data are concentration data under different pressures, so direct comparison cannot obtain accurate data. It is understandable that for a solvent under a unit volume, when the pressure increases and the volume decreases, its concentration will inevitably increase, and the increase process is proportional to the pressure increase. Therefore, the first pressure value, the first concentration data and the second concentration data determine the current particle collection rate, which can meet the following conditions:

[0055] ;

[0056] in, is the current particle collection rate, is the first concentration data, is the second concentration data, is the first pressure value, is the current atmospheric pressure.

[0057] It is understandable that the above steps can avoid the influence caused by pressure and obtain more accurate results for the collection rate. It should be noted that in this embodiment, the pressure of the second pipeline is equal to that of the outside world, so Directly select the current atmospheric pressure. In other embodiments, depending on different devices, The value may need to be re-measured and the specific process will not be described here.

[0058] Afterwards, a preset particle collection rate is obtained, and the target particle collection rate can be determined based on the preset particle collection rate and the current particle collection rate.

[0059] It is understandable that the preset collection rate is the collection rate to be achieved according to the demand. When the exhaust pipe is connected to the atmosphere, the preset collection rate can be obtained according to the relevant environmental protection standards. In other cases, such as when the subsequent process requires a certain amount of pollutants for special treatment or reaction, the preset collection rate can also be determined, which is not limited here.

[0060] It can be understood that the target collection rate is the difference between the preset collection rate and the current collection rate, that is, it satisfies:

[0061] ;

[0062] in, is the target particle collection rate, is the preset particle collection rate.

[0063] S103: Based on the target particle collection rate, determine an overall control scheme, where the overall control scheme is used to control the pressure regulation system and the condensation recovery component.

[0064] After the target particle collection rate is determined, the current exhaust gas recovery device can be regulated through the overall control scheme so that it can correctly change the current collection rate. It can be understood that in this embodiment, if the preset collection rate is greater than the current collection rate, that is, the target collection rate is a positive number, it can be determined that the current collection rate is insufficient, that is, it is necessary to enhance the collection effect on pollutant particles. At this time, the overall control scheme can be a scheme to increase the collection rate. On the contrary, if the preset collection rate is less than the current collection rate, that is, the target collection rate is a negative number, it can be determined that the current collection rate is too high, that is, it is necessary to reduce the collection effect on pollutants. At this time, the overall control scheme can be a scheme to reduce the collection rate.

[0065] S104: Determine a pressure control scheme and a condensation control scheme based on the overall control scheme.

[0066] It can be understood that in this embodiment, the influence on the collection rate is mainly caused by the combined effect of the pressure control system and the condensation collection system. When the collection rate needs to be increased, it can be done by increasing the power of the condensation system or the power of the boosting system. However, due to the related linkage between the condensation collection system and the boosting system, the boosting system has a greater impact on the collection rate during operation than the condensation system. Therefore, from the perspective of energy saving, when the collection rate needs to be increased, the boosting system should be regulated first. Therefore, if the type of the overall control scheme is the scheme for increasing the collection rate, the pressure regulation scheme is determined to be the boosting scheme, that is, the scheme for first regulating the boosting system and then regulating the scheme for the condensation system.

[0067] Specifically, the pressure regulating system can be controlled based on the pressurization scheme so that the pressure value in the condensation recovery component reaches a preset pressure value. It is understandable that when the pressure in the condensation recovery component increases, the concentration of pollutants increases and the condensation process also intensifies, but since heat is also generated due to the compression of the gas during the pressurization process, a preset pressure value can be obtained through multiple tests or data processing, at which the condensation recovery component can achieve the maximum collection efficiency.

[0068] Specifically, the target temperature value can be directly obtained, and the target temperature value is the temperature value in the pipe passing through the condensing component. Then, based on the target temperature value and the second pressure value, the condensing scheme can be determined. As an implementation method, in the process of determining the condensing scheme, the power of the condensing system can be determined first, and then the control variables can be selected through different pressures to finally determine the appropriate condensing scheme. It should be noted that in the process of demonstration, in order to ensure the accuracy of the results and the principle of giving priority to controlling the pressure regulation system, the following should be met:

[0069] ;

[0070] in, is the target temperature value, is the effective condensing power of the condensation recovery assembly adjusted according to the condensation scheme, is the effective condensing power of the condensation recovery assembly before adjustment, is the second pressure value, is the volume of gas passing through the condensation recovery component per unit time, is the specific heat capacity of gas, is a constant.

[0071] In other embodiments, if the type of the overall control scheme is the collection rate reduction scheme, it can be determined that the pressure regulation scheme is a temperature increase scheme, that is, the temperature of the condensation component is increased to reduce the collection rate.

[0072] It is understandable that in the process of reducing the collection rate, from the perspective of energy saving, the priority should be to reduce the condensation recovery component with higher energy consumption. Therefore, the condensation recovery component is controlled through the temperature increase scheme. By increasing the temperature of the condensation component, the collection rate can be directly reduced.
