Oil smoke filtering device

Abstract

The invention discloses an oil smoke filtering device. The oil smoke filtering device comprise at least two vertically arranged filtering channels; the filtering channels are arranged in parallel along the transverse direction; each filtering channel is composed of adjacent vertically arranged separating plates, and possesses at least on zigzag part, so that at least one filtering channel is a zigzag channel; and oil smoke blocking parts are transversely arranged in the filtering channels. Advantages are that: filtering channel area and contact area with oil smoke of the zigzag channels are relatively large, and fluidity of grease obtained via filtering is high; resistance loss of the transverse oil smoke blocking parts arranged in the filtering channels is small, collision filtering effect on particles with different size is excellent, oil smoke separation and filtering effect can be improved effectively without obvious increasing of windage resistance, and excellent oil smoke separation efficiency is obtained via combination with the zigzag channels; the oil smoke filtering device is simple in the whole structure, is convenient for maintenance, and is suitable for oil smoke filtering of a plurality of smoke exhaust ventilators.

Description

technical field [0001] The invention relates to a range hood, in particular to an oil fume filtering device for separating the oil fume in the gas. Background technique [0002] At present, most of the oil fume purification devices of the collision method on the market adopt mesh or labyrinth type, reverse buckle type purification structure, etc. The mesh structure filter structure is related to the diameter of the hole. The smaller the hole, the better the oil fume filtration effect, but the wind resistance is large and the durability is poor. , it is easy to block and cause failure, and the maintainability is poor; the labyrinth filter structure changes the flow direction through multiple protruding plate structures in the flow channel, and the wind resistance is large, and the filtering effect is related to the number of labyrinths; various shapes of buckle filter structures, The filtration effect is related to the size of the flow channel, the flow channel is small, the ...

AI Technical Summary

Problems solved by technology

Although the oil fume separation plate has a certain oil fume separation effect after forming a bent air duct that changes the wind direction sharply, it has the following two main defects: first, the resistance loss is large; second, only large-sized particles can hit Oil filter plate, small particles will flow away with the airflow
