1. The purification efficiency of cooking fume purifier is low.

Some restaurant shopkeepers do not know enough about environmental protection, and in order to be cheap, they installed a cheap but inferior quality cooking fume purifier, which only requires a device. The installed cooking fume purifier has no actual purification effect, and the cooking fume purifier has become a decoration, and the oil around the restaurant smoke outlet overflows, seriously affecting the living environment of the surrounding residents and polluting the atmospheric environment.

2. The cooking fume purifier and smoke exhaust fan do not match

Although some restaurant owners have installed efficient cooking fume purifiers, the purification effect is still not good. This situation is because the processing capacity of the oil fume filter and the air volume of the exhaust fan are not correctly matched and installed, and the amount of oil fume exhaust gas discharged by the exhaust fan greatly exceeds the processing capacity of the oil fume purifier, which leads to the oil fume purifier not being able to treat it, and the oil fume exhaust gas is discharged to exceed the standard.
