Description

Technical Field

[0001] The invention relates to the technical field of oil fume purification, and in particular to an oil fume purification device for restaurant kitchens. Background Art

[0002] The fumes we usually emit when cooking are a large amount of thermal oxidation decomposition products produced by cooking oil and food under high temperature conditions. In recent years, people have paid more and more attention to the living environment, and the indoor environment has become the focus of people's attention. With the development of the economy and the improvement of people's living standards, the problem of kitchen fumes has become a hot topic of concern, and more and more people have begun to realize the adverse effects of kitchen fumes on the indoor environment. The existing treatment method is to filter through a smoke extractor or discharge it directly into the atmosphere through a fan, which can reduce the physical harm of fumes to cooking personnel.

[0003] When purifying the oil fume generated in the restaurant kitchen, the oil fume is mostly purified and filtered through a filtering device. However, after the filter plate has been used for a long time, a large amount of oil residue will adhere to its surface, which will affect the normal use of the filter plate. Therefore, we propose a restaurant kitchen oil fume purification device. Summary of the invention
