Ankerui Catering Oil Fume Online Monitoring Platform Manufacturer

Description :

　　The TGS2602 model sensor is selected for the inspection of gaseous compounds. This sensor has stable characteristics and many advantages: low functional loss, sensitivity to cooking vapors, low cost, good reliability, and easy use of power circuits. The higher the concentration value of the tested gas, the higher the conductivity of the sensor components. By using the change in conductivity, the corresponding change in gas concentration value can be calculated.

　　The total power supply voltage of a part of the power circuit is 9V, and the measurement working voltage of the gas sensor needs to be stable at 2.9V. Therefore, in the design scheme of the article, a constant current source integrated icTL431cdr is applied to reduce the 9V working voltage to a stable 2.9V for the sensor application. When the concentration value of the vapor changes, the resistance value of the measuring resistor also changes accordingly. Because the individual working voltage obtained by the load R7 after the voltage divider circuit is too small to further solve the problem, a voltage follower and operational amplifier are added to increase it by 2 times, and then the working voltage value is transmitted to the microcontroller to solve the problem. In this system, there is a corresponding relationship between the concentration of oil fume gas and the temperature value. The determination of oil fume concentration requires temperature and humidity as references, and the change in temperature and humidity can also be used to observe whether the merchant has used the detection equipment. If the equipment is not enabled, the temperature and humidity values will not change.

　　High voltage electrostatic induction oil fume purifier machine equipment

　　The high-voltage electrostatic induction method is based on the basic principle of electrostatic induction accumulation. Due to the strong electrostatic field effect of the induced electrification conductor, the electric arc discharge induces electricity in the oil particles, hydrolyzes the droplets, and creates many new induced electrification oil particles. When they enter the collection area and are subjected to electric field force, they oxidize and exercise towards the sun, thereby promoting the extraction of remaining kitchen oil fume particles from the smoke and dust, making the solved kitchen oil fume vapor meet environmental standards. Waste engine oil is injected into the oil collection tank and discharged into the collection equipment through the oil discharge pipe. The advantage is high cleaning efficiency and low frictional resistance. The defect is long-term application, which is prone to settling oil stains, reducing the ability of concentration differentiation work, and endangering cleaning efficiency. It cannot be cleaned in the middle and later stages, which can easily lead to fire accidents and require timely personnel, resulting in significant wear and tear. Generally, installing a metal filter element in front of high-voltage electrostatic induction equipment can increase the load of the electrostatic field and improve the actual cleaning effect.

　　Composite oil fume purifier machine equipment

　　Composite oil fume purifier machine equipment refers to oil fume purifier machine equipment designed using two or more cleaning methods. Various technical aspects fill in the gaps between each other, greatly improving cleaning efficiency compared to previous technical aspects, and having numerous industry prospects. The sales market is relatively complete, with high-voltage electrostatic induction technology as the key, supplemented by other cleaning technologies to achieve the goal of improving various indicators of kitchen oil fume discharge. Common mechanical equipment includes suction filtration and high-pressure electrostatic induction composite oil fume filters

　　The front-end mechanical equipment filtration control module and the back-end development high-voltage electrostatic induction control module are used in conjunction with each other, which is a two-stage oil fume purifier method. The mechanical equipment filtration equipment can physically separate large particle welding smoke particles. Although the cleaning efficiency is not high, it is suitable as part of the preparatory treatment for initial and intermediate cleaning, thereby reducing the pressure of back-end development work. After undergoing preparatory treatment, the smaller droplets and fine particles enter the high-pressure electrostatic induction area for secondary solution, and the low concentration kitchen fumes that have been resolved are discharged through the inlet and outlet.

　　Ankerui Catering Oil Fume Online Monitoring Platform Manufacturer I. Introduction to Catering Oil Fume Monitoring Cloud Platform

　　1. Function

　　Cooking fumes are one of the main sources of volatile organic compounds (VOCs) and PM10 in the atmosphere. In recent years, with the strengthening of environmental protection governance, various levels have continuously strengthened the full coverage installation of oil fume purifiers by catering operators, but there are still some problems and loopholes in supervision.

　　(1) Poor proactive environmental awareness: Most small and medium-sized catering owners believe that holding certificates from the industry and commerce, food and medicine departments is enough to operate legally, ignoring environmental impact assessment approval, resulting in the installation of kitchen fume purification facilities without standardized requirements;

　　(2) Due to the direct impact of the power of oil fume purification facilities on the purchase and installation cost and oil fume purification effect, despite the installation of purification equipment, complaints about poor purification effect and oil fume disturbance to residents still occur from time to time;

　　(3) Difficulty in self-regulation of businesses: During the inspection process, although catering owners installed oil fume purification equipment, they did not consciously maintain and use it, and the effect of regular cleaning was not significant;

　　(4) Difficulty in supervision: There are a huge number of catering enterprises, and it is impossible to achieve full coverage through human supervision. Some monitoring projects require multiple sampling by testing companies and equipment, and require a long time for analysis. The cost and difficulty of supervision are high.

　　In order to make up for the loopholes in the existing catering industry's e-liquid monitoring and facilitate the supervision of regulatory authorities, the Ankerui oil fume monitoring cloud platform has emerged.

　　Pollution and Operation Standards of Cooking Kitchen Fume Environment in China

　　According to material statistics and analysis, the vast majority of households in China use range hoods, most of which do not have an oil and gas separator function. They simply connect the exhaust duct with a centrifugal fan to complete the function of a smoking and smoke exhaust system. This has little practical effect on cleaning kitchen fumes and volatile organic compounds (VOCs) and other air pollutants, resulting in oil stains immediately being discharged outdoors and causing certain environmental pollution to the air.

　　The "Emission Standards for Kitchen Fumes in the Catering Industry (Trial)" (GB18483-2001) is currently a reasonable national industry standard for kitchen fumes in China. However, due to the requirement of using purified organic solvents as chemical drugs that are strictly prohibited worldwide, it is urgent to revise or find alternative experimental reagents for this standard. On the basis of national industry standards, Shandong Province, Shanghai City, Tianjin City and other places have successively issued industry standards for kitchen fume discharge in the catering industry that are stricter than national industry standards. However, these standards have not fully considered the manipulation requirements of VOCs in kitchen fume environmental pollution, and there is a lack of relative pollution limit values for kitchen fume discharge in homes.

　　The oil fume detection probe includes a sensor, an AD converter, and a CAN bus module. Among them, sensors include gas sensors and temperature sensors. The gas sensor adopts the TGS2602 model sensor. This sensor has stable performance and many advantages: low power consumption, sensitivity to cooking gases, low cost, strong stability, and simple application circuit. For temperature detection, DS18B20 temperature sensor is used, which has a temperature measurement range of -55~125 ℃ and a resolution of up to 0.0625 ℃. It can be used in oil fume environments. It has the characteristics of being able to directly output digital signals without the need for an A/D converter, having fewer peripheral circuits, and being suitable for long-distance transmission. The CAN bus communication in this article complies with the ISO11898 standard. Adopting the ADM3053 module, it integrates a DCDC converter internally, eliminating the need for optocoupler isolation. This not only isolates the signal and power supply between the microcontroller and the oil fume detection probe, but also saves resources.
