Abstract
Description
Technical Field
[0001] This invention relates to the technical field of refrigeration equipment, and in particular to a method for purifying oil fumes, an oil fume purification device, and a storage medium. Background Technology
[0002] The catering and food processing industries generate a large amount of oily fume pollutants during production. These fumes not only contain solid particulate matter, but also a variety of volatile organic compounds and odor substances, making them complex in composition. Direct emission of these fumes poses a serious threat to the atmospheric environment and human health.
[0003] In related technologies, oil fume purification generally operates at a preset fixed power. When the concentration of oil fume at the inlet is low, the fixed parameters cause the equipment to be "overpowered" and result in excessive energy consumption. When the concentration spikes suddenly, the purification may be incomplete due to insufficient processing capacity, leading to excessive emissions. Summary of the Invention
[0004] The main objective of this invention is to provide a method, device, and storage medium for purifying oil fumes, which aims to improve the efficiency of oil fume purification while effectively reducing energy waste and thereby improving energy utilization.
[0005] To achieve the above objectives, the present invention proposes a method for purifying oil fumes, comprising the following steps: S10. The oil fumes are subjected to electrostatic adsorption treatment, filtration treatment, chemical oxidation treatment and refrigeration treatment in sequence. S20. Obtain the oil fume concentration data at the electrostatic adsorption site and the oil fume concentration data at the chemical oxidation site; S30. Adjust the voltage at the electrostatic adsorption point based on the oil fume concentration data at the electrostatic adsorption point, and adjust the voltage at the chemical oxidation treatment point based on the oil fume concentration data at the chemical oxidation point.
[0006] In one embodiment, step S30 further includes: acquiring first oil fume concentration data at the electrostatic adsorption site, comparing the first oil fume concentration data with preset data, and adjusting the voltage at the electrostatic adsorption site; The second oil fume concentration data at the chemical oxidation site is obtained, and the second oil fume concentration data is compared with preset data to adjust the voltage at the chemical oxidation site.
[0007] In one embodiment, step S30 further includes: acquiring first oil fume concentration data at the electrostatic adsorption site, comparing the first oil fume concentration data with the previous measurement data at the electrostatic adsorption site, so as to adjust the voltage at the electrostatic adsorption site; The second oil fume concentration data at the chemical oxidation site is obtained, and the second oil fume concentration data is compared with the previous measurement data at the chemical oxidation site to adjust the voltage at the chemical oxidation site.
[0008] In one embodiment, the filtration process includes a medium-efficiency filter screen for filtering the oil fumes after the electrostatic adsorption treatment.
[0009] In one embodiment, the filtration process further includes activated carbon with a fiber layer to simultaneously filter and adsorb the oil fumes filtered by the medium-efficiency filter.
[0010] In one embodiment, the chemical oxidation treatment includes a high-efficiency ion tube, which generates high-energy ions to oxidize aldehyde odor substances in the cooking fumes and release reactive oxygen species and free radicals for disinfection and sterilization.
[0011] In one embodiment, a catalytic treatment is further included, which is located downstream of the chemical oxidation treatment and is used to accelerate the oxidation reaction at the chemical oxidation treatment.
[0012] In one embodiment, current data at the electrostatic adsorption site and current data at the chemical oxidation site are acquired; when the current data at the electrostatic adsorption site exceeds a preset value, the electrostatic adsorption operation is stopped; and / or When the current data at the chemical oxidation point exceeds a preset value, the chemical oxidation process is controlled to stop.
[0013] The present invention also proposes an oil fume purification device, the oil fume purification device comprising: a memory, a processor, and an oil fume purification method of the oil fume purification device stored in the memory and executable on the processor, wherein when the control program of the oil fume purification device is executed by the processor, the steps of the oil fume purification method of the oil fume purification device as described above are implemented.
[0014] The present invention also proposes a computer-readable storage medium storing a control program for an oil fume purification device, wherein when the control program for the oil fume purification device is executed by a processor, the steps of the oil fume purification method of the oil fume purification device as described above are implemented.
[0015] The technical solution of this invention first treats the cooking fumes with electrostatic adsorption and filtration to remove particulate matter. Then, chemical oxidation removes odorous substances such as aldehydes. The purified fumes are then disinfected to enhance the purification effect. Finally, the purified airflow is cooled, providing a better working environment for kitchen staff and improving user experience. Furthermore, by dynamically adjusting the voltage of electrostatic adsorption and chemical oxidation based on real-time fume concentration data, the system automatically adapts to fluctuations in fume concentration.

[0022] Reference Figure 1 This invention proposes a method for purifying oil fumes, comprising the following steps: S10. The oil fumes are subjected to electrostatic adsorption treatment, filtration treatment, chemical oxidation treatment and refrigeration treatment in sequence. S20. Obtain the oil fume concentration data at the electrostatic adsorption site and the oil fume concentration data at the chemical oxidation site; S30. Adjust the voltage at the electrostatic adsorption point based on the oil fume concentration data at the electrostatic adsorption point, and adjust the voltage at the chemical oxidation treatment point based on the oil fume concentration data at the chemical oxidation point.
[0023] The technical solution of this invention first treats the cooking fumes with electrostatic adsorption and filtration to remove particulate matter. Then, chemical oxidation removes odorous substances such as aldehydes. The purified fumes are then disinfected to enhance the purification effect. Finally, the purified airflow is cooled, providing a better working environment for kitchen staff and improving user experience. Furthermore, by dynamically adjusting the voltage of electrostatic adsorption and chemical oxidation based on real-time fume concentration data, the system automatically adapts to fluctuations in fume concentration. This reduces energy consumption at low concentrations and maintains processing capacity at high concentrations, improving fume purification efficiency while effectively reducing energy waste and increasing energy utilization.
[0024] In Embodiment 1, step S30 further includes: acquiring first oil fume concentration data at the electrostatic adsorption point, comparing the first oil fume concentration data with preset data to adjust the voltage at the electrostatic adsorption point; acquiring second oil fume concentration data at the chemical oxidation point, comparing the second oil fume concentration data with preset data to adjust the voltage at the chemical oxidation point. That is, by detecting the oil fume concentration at the electrostatic adsorption point and the oil fume concentration at the chemical oxidation point, and then matching the corresponding gear in the control circuit using these concentration values, the voltage values at the corresponding gears of the electrostatic adsorption point and the chemical oxidation point are adjusted; thereby enabling the purification system to accurately respond to changes in operating conditions and always operate within the optimal efficiency range, thus maximizing energy utilization while ensuring thorough purification of oil fumes.
[0025] In Embodiment Two, step S30 further includes: acquiring first oil fume concentration data at the electrostatic adsorption point, comparing the first oil fume concentration data with the previous measurement data at the electrostatic adsorption point to adjust the voltage at the electrostatic adsorption point; acquiring second oil fume concentration data at the chemical oxidation point, comparing the second oil fume concentration data with the previous measurement data at the chemical oxidation point to adjust the voltage at the chemical oxidation point. That is, Embodiment Two focuses more on the relative change trend of oil fume concentration over a short period. By comparing real-time data with previous data, the system can quickly detect whether the oil fume load is "rising sharply," "falling slowly," or "remaining stable." This sensitivity to the rate of change allows the system to react before the pollutant concentration completely exceeds the standard. For example, when the oil fume concentration at the electrostatic adsorption point is detected to be rapidly increasing, the system does not need to wait for it to reach the preset absolute upper limit; it can gradually increase the voltage in advance, thereby smoothly suppressing the concentration peak and avoiding instantaneous exceedances caused by "processing lag." This control strategy is particularly suitable for handling explosive and transient oil fumes; thus reducing the over-reliance on the accuracy of absolute concentration measurement and focusing more on the operational stability of the system itself. This helps to reduce the stringent requirements on the long-term accuracy of sensors while ensuring the purification effect, thereby improving the robustness and economy of the system.
[0026] Specifically, the filtration process includes a medium-efficiency filter to filter the oil fumes after electrostatic adsorption treatment. Electrostatic adsorption, as a pre-treatment unit, has already removed most of the liquid oil droplets and larger particles. At this point, the medium-efficiency filter, as a second line of defense, can focus on capturing smaller particles and aerosols that penetrate the electrostatic field. This division of labor avoids having a single unit handle pollutants of all sizes, thus achieving a reasonable allocation of the purification load and improving the purification efficiency of the oil fumes.
[0027] Specifically, the filtration process also includes activated carbon with a fiber layer inside, which simultaneously filters and adsorbs the oil fumes filtered by the medium-efficiency filter. By incorporating a fiber layer within the activated carbon, the dual functions of physical filtration and chemical adsorption are combined. The fiber layer acts as a pre-filter, capturing some finer particles and reducing the risk of clogging of the activated carbon's micropores. Simultaneously, the fiber layer also serves as an internal support framework for the activated carbon, preventing particles from pulverizing under airflow impact. This improves the lifespan of the activated carbon and ensures its adsorption function operates under optimal conditions.
[0028] Specifically, the chemical oxidation treatment includes a high-efficiency ion tube. This high-energy ion tube generates high-energy ions that oxidize aldehydes and other odor-causing substances in the cooking fumes, releasing reactive oxygen species and free radicals for disinfection and sterilization. While electrostatic filtration primarily treats macroscopic particulate matter, the reactive particles (such as reactive oxygen species and free radicals) generated by the high-energy ion tube possess extremely high chemical activity. They can directly attack and break down odor-causing and toxic gas molecules such as aldehydes and alkanes in the cooking fumes, ultimately converting them into harmless carbon dioxide and water. This is a fundamental chemical decomposition, significantly eliminating odors and VOCs and reducing secondary pollution. Furthermore, the released reactive oxygen species and free radicals effectively destroy the cell structure of bacteria and viruses, achieving simultaneous air disinfection. This allows workers in kitchens and other places with high concentrations of cooking fumes to breathe clean air, thereby improving the user experience.
[0029] Furthermore, the process includes a catalytic treatment downstream of the chemical oxidation treatment, which accelerates the oxidation reaction at the chemical oxidation site. This catalytic treatment significantly improves the rate and thoroughness of the oxidation reaction. The core function of the catalyst is to reduce the activation energy required for the chemical reaction. Based on the free radicals and reactive oxygen species generated by the high-energy ion tube, the catalyst provides a more efficient pathway for the reaction between these high-energy particles and pollutant molecules, thereby greatly accelerating the reaction rate and achieving a deeper level of purification in a shorter treatment time. Secondly, the combination of chemical oxidation and catalytic treatment achieves efficient energy utilization. Due to the presence of the catalyst, the system does not need to increase the discharge intensity (i.e., voltage) of the high-energy ion tube to achieve the same purification effect, thus directly reducing the overall energy consumption of the system and embodying the principle of "green chemistry." In addition, the catalyst can promote the further reaction of some intermediate products that are difficult to oxidize directly, preventing the accumulation and emission of these byproducts, ensuring that pollutants are more completely mineralized into carbon dioxide and water, and improving the cleanliness of the final emission gas.
[0030] In electrostatic adsorption and chemical oxidation units, an abnormally high current (exceeding a preset value) is usually a sign of serious equipment problems, such as short circuits between plates in the electrostatic field, insulator breakdown, or localized arcing due to oil buildup. For chemical oxidation units, it may be due to aging of the ion tube or circuit failure. Without timely intervention, not only will the purification function be lost, but permanent equipment damage or even a fire risk may result. Therefore, in one embodiment, current data at the electrostatic adsorption point and the current data at the chemical oxidation point are acquired. When the current data at the electrostatic adsorption point exceeds a preset value, the electrostatic adsorption operation is stopped; and / or when the current data at the chemical oxidation point exceeds a preset value, the chemical oxidation operation is stopped. By monitoring the current in real time, the operation of dangerous units can be immediately "cut off" at the initial stage of a fault, effectively preventing the expansion of the fault range and the occurrence of catastrophic consequences.
