Accuray catering fume monitoring cloud platform helps the battle against air pollution

1.
Foreword This standard
is formulated in order to implement the Law of the People's Republic of China on the Prevention and Control of Atmospheric Pollution and prevent and control the pollution of the atmospheric environment and living environment by oil fumes in the catering industry.
This standard specifies the allowable emission concentration of fumes in the catering industry and the removal efficiency
of fume purification equipment.
This standard is a trial standard and has been implemented
since January 1, 2002.
In November 2021, the "Opinions on Deepening the Battle against Pollution" (hereinafter referred to as the "Opinions")
was issued.
The "Opinions" pointed out that by 2025, the ecological environment will continue to improve, the total amount of major pollutants will continue to decline, the carbon dioxide emissions of GDP will decrease by 18% compared with 2020, the concentration of fine particulate matter (PM2.
5) in cities at the prefecture level and above will decrease by 10%, and the proportion of
days with good air quality will reach 87.
5%.
Recently, Beijing-Tianjin-Hebei and many surrounding provinces and cities have issued relevant documents to formulate provincial (municipal) air pollution prevention and control targets and fight the battle
against pollution in depth.
Keywords: catering fumes air prevention and control oil fume monitoring 2.
Background analysis In recent years, local ecological and environmental bureaus have taken the in-depth implementation of the "air pollution prevention and control battle" as the starting point, changed their work style, improved their capabilities, strictly performed their duties, strived to do a good job in various tasks of ecological environmental protection, persevered and deepened the battle against air pollution, strengthened organizational leadership, strengthened responsibilities, refined tasks, hardened measures, and promoted the continuous improvement
of air quality in various places.
Food and beverage 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, the state, provinces and municipalities have continuously strengthened the installation of fume purifiers by catering operators, but there are still some problems and loopholes
in supervision 。 (1) Poor awareness of active environmental protection: Most small and medium-sized catering owners believe that they can operate legally by holding certificates from departments such as industry and commerce, food and medicine, ignoring EIA approval, resulting in no standard requirements for the installation of kitchen fume purification facilities; (2) Large difference in installation effect: because the power of oil fume purification facilities directly affects the purchase and installation cost and the disparity in oil fume purification effect is too large, complaints about oil fume disturbing people that are installed but have poor purification effect also occur from time to time; (3) It is difficult for businesses to self-discipline and supervise: During the inspection process, although the catering owner installed the oil fume purification device, the effect of conscious maintenance and use and regular cleaning was not obvious; (4) Difficulty in supervision: The number of catering enterprises is huge, and full coverage
cannot be achieved by relying on human supervision.

Accuray catering fume monitoring cloud platform helps air pollution prevention and control AcrelCloud-3500 catering fume monitoring cloud platform monitors the operating status of catering fume treatment equipment to achieve start-up rate and purification efficiency monitoring
。 At the same time, collect oil fume emission data, warn abnormal enterprises with excessive emissions, and warn the cleaning of oil fume purification equipment for overdue cleaning, assist regulatory departments to quickly intervene, urge catering enterprises to rectify equipment, and regularly clean and maintain, change from traditional civil air defense to technical defense, realize remote centralized monitoring by regulatory departments, greatly reduce labor costs, and reasonably solve problems such as
weak environmental law enforcement and difficult supervision in place 。 The sampling probe of the oil smoke concentration online monitor is installed in the oil smoke pipeline before and after the oil fume purification equipment, measures the oil smoke concentration, particulate matter concentration, non-methane total hydrocarbon concentration and other non-electrical monitoring factors, communicates with the oil smoke concentration online monitor through 485, and then uploads the oil smoke concentration online monitor to the cloud server
through the 4G full network communication HJ212-2017 pollution source online automatic monitoring (monitoring) system data transmission standard 。 The catering fume monitoring cloud platform is deployed on Alibaba Cloud servers to receive, count, store, and display data, and provide managers with WEB and mobile APP access, and managers can use web pages, mobile apps and other forms to apply platform functions
。 The system structure diagram is as follows: 4.
Main functions of the platform 4.
1 Real-time data monitoring Real-time monitoring of the total hydrocarbon values of the installation merchant of oil smoke, particulate matter, non-methane total, and recording relevant historical data and curves, the operating status of the purifier fan 4.
2 Alarm work order processing, closed-loop dispatch and closed-loop processing of the generated alarm work order, upload on-site pictures, documents and remarks; Record detailed work order processing process and progress 4.
3 Equipment cleaning and maintenance, patrol inspection ledger Record the daily cleaning of equipment, upload on-site cleaning, maintenance pictures, signatures of relevant personnel and other information 4.
4 Data report analysis Correlation analysis of uploaded oil smoke and other data, generate corresponding over-standard rankings, enterprise and user analysis reports, help law enforcement departments reasonably and timely understand the data exceeding in each region in the jurisdiction, and support data report analysis and customization
。 4.
5 Third-party platform data docking Can seamlessly connect with third-party government affairs systems, realize data interoperability, and consistent protocol interfaces 5.
