　　Analysis of the Causes of Kitchen Smoke Exhaust and Environmental Pollution Damage

　　The entire process caused by kitchen smoke exhaust

　　Kitchen exhaust refers to the evaporation of vegetable oils, soil organic matter, and substances that undergo causticization and catalytic cracking during the cooking and production of food ingredients. When cooking, vegetable oils and fats are exposed to heat. When the temperature reaches 170 ℃ (the smoke point of vegetable oils), blue and thick smoke gradually appears. With the continuous increase of cooking temperature and the addition of food, the dissolution rate of vegetable oils and fats accelerates, and the moisture content in food evaporates and rises significantly. A part of it that is cold and misty, together with kitchen fumes, produces the visible oil smoke. The volatile organic compounds, vegetable oils, dissolved substances in food, and various reactive substances mixed together at high temperatures produce kitchen fumes, accompanied by a stimulating odor.

　　The sales market for oil fume purifiers and equipment is not standardized

　　During the entire process of kitchen oil fume pollution control, the supervisory agency found that although some restaurants' machinery and equipment contained testing and compliance reports provided by the organization, the model specifications and exhaust air volume on the factory nameplate of the oil fume purifier were mostly inconsistent. Even a large number of factory nameplates for oil fume purifiers have been removed. The catering owner stated that there was no factory nameplate during installation regarding this matter. The reason for such a situation may be that different types of smoke and dust purification machines and equipment that cooperate with each other have the same testing report. All products of the same type are subject to quality inspection reports, resulting in the inability to ensure the quality of smoke and dust purification equipment.

　　Manufacturer of Ankerui Hotel Oil Fume Automatic Monitoring Platform 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. The oil fume monitoring module communicates and exchanges data with the cloud platform through 2G/4G, and the system can monitor the startup and operation status of enterprise catering equipment; Implement functions such as startup rate monitoring, purification efficiency monitoring, facility shutdown alarm, pending cleaning alarm, abnormal alarm, etc; Perform statistical analysis, ranking, and other statistical functions on collected data; Compared to traditional electrostatic monitoring methods, it is safer and more effective.

　　2、 Structure of Catering Oil Fume Monitoring Cloud Platform

　　The platform collects data on the operating status of catering fume treatment equipment and the concentration of fume emissions, automatically alerts and warns enterprises with excessive emissions and abnormal situations. Regulatory authorities can quickly handle the situation, urge catering enterprises to rectify their equipment, and regularly clean and maintain them to achieve emission reduction, environmental protection, and non disturbance to the public.

　　Install monitoring terminals on site to monitor the working status of the oil fume purifier in real time, including the current of equipment operation. At the same time, compare and analyze the particulate matter concentration at the exhaust outlet. Once the emissions exceed the standard, the system will issue abnormal signals.

　　Oil fume monitoring equipment is used to monitor data such as oil fume, particulate matter, NmHc, etc

　　Purifier and fan work together to purify oil fumes, while monitoring the current of the purification equipment

　　The device uploads the collected data to a remote cloud server via 4G network

　　System software design and communication module configuration. Due to the long distance between the oil fume detection node (lower computer) and the server (upper computer), wired transmission costs are high and feasibility is poor. Therefore, this article adopts GPRS wireless communication technology. This technology has the characteristics of high data transmission rate, low cost, and zero disconnection. The communication function in the system is based on the TCP/IP network communication protocol. The oil fume data is packaged according to the communication format designed in this article, and the packaged data is sent from the lower computer to the upper computer through GPRS wireless communication. The processor STM32F407 can establish a TCP connection with the upper computer through AT instructions and send data to the upper computer according to the specified communication format. In the data transmission function, the upper computer automatically sends feedback data to the lower computer after receiving the data.

　　The pollution caused by cooking fumes in restaurant kitchens has become one of the key sources of air pollution in big cities, and has received attention. Analyzed the causes and harm of kitchen smoke exhaust environmental pollution, discussed the current situation of kitchen smoke exhaust environmental pollution discharge and operation norms in various countries around the world, and proposed preventive measures for kitchen smoke exhaust environmental pollution in China and household installation of range hood cleaning technology.

　　The harm of kitchen smoke exhaust

　　Cooking kitchen fumes at home, as a key source of inhalable particulate matter and volatile organic compounds (VOCs) in big cities, are one of the primary conditions for causing severe haze environmental pollution. The volatile organic compounds (VOCs) in kitchen exhaust react with nitrogen oxides in the natural environment, increasing the reducibility of the air, exceeding the standard for reactive oxygen species, causing photochemical pollution, and accelerating the production of secondary fine particulate matter; Secondly, it is an immediate source of PM2.5 emissions; Thirdly, the discharge of kitchen fumes and air pollutants will continue to harm air visibility. It is one of the key sources of volatile organic compounds (VOCs) and PM2.5 in the air. Kitchen fumes from cooking at home contain a variety of harmful components, which have toxic side effects on the lungs, immune system, and carcinogens, especially carcinogenic substances such as benzene derivatives (PAHs), which can cause great harm to the body. According to relevant materials, among the factors that can cause liver cancer, cooking kitchen fumes are only the second highest risk source for thick smoke reaching the deep respiratory system after "deep smoking". Many women in China who do not smoke may develop liver cancer due to long-term exposure to kitchen smoke. In addition, some aldehyde macrolide chemicals in cooking kitchen fumes (such as indoor, hydrogen bromide, etc.) also have the effects of carcinogens, fetal malformations, and sudden changes.
