Case Study: Huawei Group's Oil Fume Purification with 300,000 CFM

As a globally renowned enterprise with a large number of employees, Huawei Group boasts a vast catering supply scale in its canteens. However, with the extension of canteen operating hours and the continuous expansion of catering business, the issue of cooking fumes has gradually become prominent. Recently, there have been some problems with the cooking fume emissions in Huawei Group's canteens, with concentrations exceeding the standard. This not only affects the air quality inside the canteens, impacting the dining environment of employees to a certain extent, but also poses a potential pollution risk to the surrounding environment. Some cooking fume purification equipment has aged, leading to a decrease in purification efficiency and unable to meet the increasing demand for cooking fume treatment. Moreover, due to the diverse cooking methods in the canteens and the complexity of cooking fume components, the odor problem is also prominent, causing a negative experience for employees and surrounding residents. These cooking fume environmental issues urgently need to be addressed to safeguard employee health and ensure the sustainable development of the enterprise, while also complying with environmental protection requirements.
