In order to solve the problem of difficult lampblack monitoring in the catering industry, the online monitoring platform of Express Bus has been deployed in many places after various tests, realizing multi-point monitoring and real-time online monitoring, overcoming the problem of lampblack monitoring, and allowing the regulatory authorities to fully grasp the lampblack emission in the catering industry in real time. Nowadays, more and more restaurants are equipped with fume purification equipment to reduce the pollution of fume to the atmosphere and improve the air quality of shops, kitchens and customers. However, there are still difficulties in monitoring oil fume, mainly due to the following points:

First, the characteristics of the catering industry

Due to the huge scale of the catering industry and the large number and dispersion of soot outlets, it is extremely difficult to monitor only by manpower, and it is impossible to achieve full coverage of monitoring.

Second, the detection method

For the detection of fume emission concentration in catering units, according to the traditional detection method, not only the on-site detection conditions are high, but also the collected samples need to be brought back to the laboratory for analysis. This kind of detection cycle is long, and the real-time monitoring data can not be obtained quickly on site, which leads to the difficulty of law enforcement in on-site monitoring.

Third, poor awareness of environmental protection.

Catering businesses are not aware of environmental protection, and do not install and use oil fume purification equipment as required, which leads to the problem of oil fume pollution can not be fundamentally solved.

Fourth, self-discipline is low.

Individual catering businesses do not pay much attention to the operation of oil fume purifier equipment, and do not consciously do as required in the cleaning and maintenance of equipment.
