What is the function of the oil fume purifier? Can it really remove oil fume?

Recently, Xiaobian received a message from a netizen who was engaged in catering, asking me if the lampblack purifier can really remove lampblack. Before answering this question, we must first let everyone know what a fume purifier is.

an oil fume purifier refers to a device for treating oil fume waste gas. The lampblack purifier is mainly used for purifying the lampblack discharged from the kitchen at low altitude; Used in hotels, restaurants, restaurants, restaurants, schools, institutions, factories and other places; Food frying and cooking processing industries; Oil spill heat treatment workshop, oil mist lubrication workshop, workpiece welding workshop and olefin boiler discharge and other industrial occasions.

Generally speaking, the oil fume purifier is a device for treating kitchen oil fume exhaust. It is very different from the general range hood. The range hood has no oil fume purification function, but only pumps the oil fume from indoor to outdoor (if the restaurant only installs the range hood, there is a great chance that it will be complained by the surrounding residents or inspected by the environmental protection department, and in serious cases, it will be fined or closed for rectification). The lampblack purifier has the function of lampblack purification, and the purification efficiency can reach 95%~98% by reasonably matching the general purification efficiency. However, the oil fume purifier is only one of the key equipment in the oil fume purification project, and it also needs supporting smoke hood, fan and exhaust pipe. There are many methods to treat oil fume in the market (I won't introduce them one by one), and the most commonly used method is high-voltage electrostatic treatment (hood+electrostatic process).

purification principle of high-voltage electrostatic oil fume purifier

Technical advantages of high-voltage electrostatic oil fume purifier:

1. Large treatment air volume and small pressure loss. It can be operated under high humidity.

2. One-pass removal rate can meet the purification requirements.

3. The diameter range of particles effectively removed is large.

Tips: After the high-voltage electrostatic oil fume purifier is used for a period of time, its purification effect will decline. At this time, it is necessary to clean the equipment (equipment movement cleaning). Generally, the cuisines with heavy smoke (Shanghai cuisine, Cantonese cuisine, etc.) should be cleaned once every 2 to 3 months, while the cuisines with heavy smoke (Sichuan Hunan cuisine, barbecue, etc.) need to be cleaned once a month or so, depending on the actual use.
