Abstract

Provided is a fume-hood type oil fume purifying device. The oil fume eliminating effect is improved, and especially the oil fume purifying effect is more obvious. According to commonly used oil fume purifying equipment at past, oil fume cannot be removed easily due to oil fume adsorption and high surface adhesive force, especially oil stains adsorbed in the equipment affect normal work of the equipment after a long time, consequently, the adsorbed oil flows out of the equipment, and the sanitation condition is quite poor; and moreover, due to the fact that oil is accumulated in a fan and a flue duct, fires are prone to occurring, and specialized maintenance personnel is needed for regular cleaning. According to the fume-hood type oil fume purifying device, a generator capable of generating foam with a washing effect and a spraying device are additionally arranged in the equipment, and through washing of the washing foam and flushing of sprayed water, smoke particles in the equipment and smoke particles attached to the interior of a honeycomb plate and a dust removing part below the honeycomb plate are washed off. The fan and the interior of the equipment are kept clean and made to work continuously, and maintenance-free and fireproof functions are achieved.

Description

technical field [0001] The invention belongs to the technical field of oil fume pollution purification in the catering industry, and in particular relates to a fume hood type oil fume purification device. Background technique [0002] At present, there are many purification devices for the treatment facilities and systems of high oil fume emission in the catering industry, which basically achieve the purpose of removing oil fume. Common practice is uniform flue gas flow, honeycomb filter and fan exhaust. However, most of the oil fume removal equipment has the problem that the oil fume attached to the flue and the hood needs to be cleaned regularly. If the smoke oil is not timely, it may cause a fire. Moreover, the problem of regular cleaning is also troublesome for users. Contents of the invention [0003] The content of the present invention is to let the flue gas pass evenly through the air flow structure of uniform oil fume. The honeycomb-type filter material filters...
