Embodiment 1

[0038] This embodiment provides a kind of oil fume filtering device with fire retardant function and high oil removal efficiency, such as Figure 1-8 As shown, it includes a filter screen 2, a deflector and a housing 1.

[0039] The filter screen 2 includes multilayer corrugated sheets (not shown in the figure) that are stacked. The crest strips 212 and trough strips 211 of the unmarked) are connected correspondingly, that is, the crest strips 212 of the first layer of corrugated sheets (not shown in the figure) are respectively fixed in sequence with the wave trough strips 211 of the second layer of corrugated sheets (not shown in the figure). , forming a filter channel. Since the filter channel is usually a through hole, in order to increase the light blocking and fire blocking effects, the crest bar 212 and the trough bar 211 are arranged in a curved shape, specifically, the crest bar 212 and the trough bar 211 are S-shaped, and the trough bar 211 It is S type. The soot ...

Abstract

The invention provides a lampblack filtering device with the fire retardance function and high oil removing efficiency. The device comprises a filter net, multiple flow guide plates and a shell; the filter net comprises multiple layers of corrugate sheets arranged in a stacked manner, each corrugate sheet comprises multiple wave crest strips and trough strips which are arranged at intervals, the wave crest strips and the trough strips of two adjacent corrugate sheets are correspondingly connected, and a filter channel is formed; multiple flow guide plates are divided into air inlet face flow guide plates and air outlet face flow guide plates, the air inlet face flow guide plates are evenly distributed on the air inlet face of the filter net, the air outlet face flow guide plates are evenlydistributed on the air outlet face of the filter net, the air inlet face flow guide plates and the air outlet face flow guide plates are arranged in a staggered manner, and the shell is used for fixing the filter net and the flow guide plates. Through the air inlet face flow guide plates, the air outlet face flow guide plates and the filter net with the S-shaped corrugate sheets, fire blocking and light blocking effects are effectively achieved, and meanwhile, the filtering and oil removing effects are greatly improved.

Description

technical field [0001] The invention relates to an oil fume filtering device with fire-blocking function and high oil removal efficiency. Background technique [0002] The oil fume filter device is installed in the range hood to filter and remove the inhaled oil fume, so as to prevent the oil fume from being discharged into the air and pollute the environment. [0003] Existing oil fume filtering devices generally filter through elongated, square or circular filter channels arranged on the filter net. When the oil fume passes through the filter channel, it contacts the side wall of the filter channel, thereby being intercepted and UV photolyzed. [0004] During use, since the filter channel is a through hole, the flame or high temperature that produces oily smoke may pass through the filter channel and spread from the air inlet side of the filter to the air outlet side, thereby damaging the range hood and even causing fire hazards. At the same time, the filtration of the fi...
