Ankerui online monitoring of oil fume emission prices in the catering industry

Description :

　　Most catering industries have a weak awareness of the harm caused by kitchen fumes

　　During the entire process of removing kitchen fumes, the office of the street community company or public workers carried out promotional planning, and the department proposed that most restaurant community owners install ash removal and cleaning equipment, and provide rewards and subsidies. People have little understanding of the risks involved and a low level of awareness of potential risks.

　　In recent years, with the continuous improvement of China's economic level, the catering industry has developed rapidly. The total number of various restaurants and food and beverage establishments has significantly increased, resulting in many food combinations and kitchen oil fume emissions. Food pairing: Kitchen fumes contain many harmful substances, including their derivatives, such as cyclohexanol and its benzene derivatives, which can harm people's physical and mental health. At the beginning of the 21st century, relevant legal and regulatory units issued the GWPB5-2000 "Emission Standards for Cooking Fumes (Trial)", which was revised and upgraded to the national industry standard GB18483-2001 in 2001. In August 2002, HJ/T62-2001 "Technical Requirements and Testing Technical Specifications for Catering Purification Equipment in the Catering Industry (Trial)" was released, and various environmentally friendly machinery continued to emerge. The cleaning technology of kitchen fumes is divided into physical and chemical methods based on the basic principles of cleaning. Physical methods include filtration, mechanical equipment chromatography separation, cleaning, adsorption, and electrostatic induction; Chemical methods include causticization and catalytic combustion device methods, and currently in China, the key is to use physical cleaning methods. The key methods for oil fume purifiers in the Chinese sales market include filter type, centrifugal fan, wet test, electrostatic induction type, and composite type. The article provides a specific description of the advantages and disadvantages of oil fume filters from the perspectives of basic cleaning principles, cleaning efficiency, and application cost. In addition, a proposal is made to clarify the direction, in order to provide ideas for future machine and equipment development and design.

　　Ankerui Online Monitoring of Oil Fume Emission Prices in the Catering Industry I. Introduction to the 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.

　　Wet dust removal and high-pressure electrostatic induction composite oil fume filter

　　The technical aspect of the close integration of wet dust removal and electrostatic precipitator is to tightly combine the electrostatic induction oil fume filter and the wet test oil fume filter, filling each other's gaps, removing the shortcomings of the other, and reducing the secondary pollution of the other. The electrostatic induction solution zone can remove large particulate air pollutants from kitchen fumes, making the solved smoke and dust meet international environmental standards. However, it cannot remove small and fine particles and odor molecular structures. Only by charging them can the actual effect of water self spraying be improved. The self spraying solution area flexibly utilizes the positive charge mirror system between free electrons and positive ions and zero potential difference objects to enhance the actual dust removal effect, and carries out relatively clean air pollutants such as smoke and odor; In addition, the use of reactive oxygen species to dissolve water and generate hydrogen peroxide as an oxidant for air oxidation of air pollutants captured by water droplets and fillers reduces the secondary pollution of cooling circulating water, and also reduces the environmental pollution of air caused by reactive oxygen species from electrostatic precipitators.

　　One of the key sources of PM2.5 environmental pollution is kitchen fume pollution. According to the detailed information of PM2.5 emissions in China, Shanghai's cleaning, restaurant, and civilian building coatings account for 5% of the total consumption, while Hong Kong's catering industry's PM2.5 emissions account for 1.07% of its total consumption. The key to cooking methods is to use frying and stir frying in areas where kitchen oil fume pollution is significantly higher than in other regions across the country. According to data information, the environmental pollution of PM2.5 in China increased from 10% to 14% from 2012 to 2017. In response to the current serious situation of kitchen oil fume pollution in restaurants, self-supporting kitchen oil fume filters are still the way to solve the problem of oil fume pollution. Single basic principle oil fume purifiers generally have their own disadvantages, such as low cleaning efficiency of centrifugal fans and inability to meet cleaning standards. Overload cleaning is more efficient than centrifugal fans, but it often requires the removal and replacement of filter materials, which is more expensive. Improper treatment of the replaced filter materials can easily cause secondary pollution. The detergent used in the entire wet cleaning process must be carefully collected, otherwise injecting it into the natural environment will cause secondary pollution. The electrostatic induction method increases over time, causing larger oil particles to adhere to the electrical level and reducing corona discharge, which in turn endangers the actual cleaning effect and continues to pose a risk of short circuit faults.

　　With the improvement of China's economic level and the rapid development trend of the catering industry, kitchen fumes have become the third largest air pollutant after industrial production emissions and exhaust emissions when paired with food. With the release of GB18483-2001, various environmentally friendly kitchen fumes solutions continue to emerge. The article analyzes the advantages and disadvantages of centrifugal fan oil fume filters, filtered oil fume filters, wet test oil fume filters, electrostatic induction oil fume filters, and their composite oil fume filters from the aspects of basic cleaning principles, cleaning efficiency, and application cost. In addition, the article also reflects on the direction, in order to provide ideas for future machine equipment development and design.
