Background of Oil Fume Online Monitoring System
With the rapid development of the economy and the improvement of people´s living standards, the requirements for environmental air quality have become increasingly stringent. The environmental quality of many cities in China is declining, and environmental pollution accidents occur from time to time. Among the many problems currently plaguing urban environmental protection, cooking fume pollution in the catering industry is a hot environmental issue closely related to the personal interests of the general public, and it is also a difficult point in urban environmental management.
The political call is also becoming more urgent. Oil fume air pollution mainly comes from the large amount of thermal oxidation decomposition products produced by edible oil and food under high temperature conditions, which are accompanied by particulate matter and aromatic hydrocarbon odors and affect air quality and people´s lives. Strictly controlling the oil fume pollution in the catering industry is an important measure to build a coordinated development of the environment, society, and economy, and create a harmonious society.
Based on the above background, our company has decided to build an online monitoring system for cooking oil fume concentration in catering services, further strengthen environmental supervision in key areas, timely, dynamically, and accurately grasp the environmental conditions of key areas, improve the ability to respond and handle emergencies, and provide scientific decision-making basis for environmental law enforcement, investigation and handling of pollution accidents, and emergency command and dispatch work. To meet the needs of urban public safety system construction and further enhance the level of environmental protection informatization.
Introduction to Oil Fume Online Monitoring System
The online monitoring system for oil fume concentration mainly consists of front-end sensors, working condition monitoring modules, host acquisition systems, data transmission modules, data receiving servers, etc.
The monitoring principle is as follows: the host collection system sends the data detected by the front-end sensors to the receiving server through a wireless transmission module via the Internet, and automatically saves and writes the data to the database. Users and owners can log in to our environmental protection information platform using a computer browser to view the data, etc; Or you can log in to the mobile phone´s WeChat official account to view relevant data.
Hardware equipment
24/7 oil fume concentration detection, no need for on-site sampling or laboratory analysis; High sensitivity oil fume detection unit, with high detection accuracy and good data repeatability. Real time monitoring of oil fume concentration, particulate matter, non methane total hydrocarbons, flue gas temperature, purifier status, fan status, and system operation status. The database supports data such as smoke concentration, temperature, fan status, purifier status, dynamic and static pressure, wind speed, etc. per minute, and the data is stored for more than three months. Equipped with over limit alarm and oil fume concentration detector dismantling alarm function, it can provide local sound and light alarm and automatically report to the monitoring center. Built in GPRS wireless communication, real-time remote transmission of detection data; Waterproof stainless steel shell, sturdy and durable; Can be paired with an online oil fume monitoring software platform.
Equipment functions
1. Real time monitoring of oil fume concentration, particulate matter concentration, and non methane total hydrocarbon concentration, with the ability to set upper limits and automatic alarm for exceeding limits; Using an open type current transformer, measurement can be done without cutting the fan or purifier cables.
2.2 current detection, capable of simultaneously detecting whether the fan and purifier are working. The detection current alarm value can be set according to the power of the fan and purifier, suitable for all power fans and purifiers.
3. Three independent working time periods can be set, with an alarm only triggered when the time limit is exceeded, and no alarm triggered when the time limit is exceeded outside the time period; 1 GPRS (optional 4G) communication interface, data can be directly uploaded to our company´s free cloud platform, government oil fume monitoring platform, or customer´s platform.
The 4.7-inch capacitive touch screen is easy to operate. Full Chinese operation interface, beautiful and elegant; AC 220V power supply, IP65 protection level, can work outdoors all year round, not afraid of rain and sun exposure.
