A flow-disturbing dynamic separation network disk used in range hoods

Abstract

A flow-disturbing dynamic separation network disk used inside the range hood, including an integrated perforated disk with four rings from the center to the surroundings. The second ring of hole ring and the third ring of hole ring; four rings of unequal diameter baffle mounting rings are installed under the hole plate, and spoiler baffles are distributed between the unequal diameter baffle mounting rings; the invention rotates at high speed, A vortex zone is formed on the suction side of the spoiler. Except for the soot particles that directly collide with the pressure side of the spoiler, most of the remaining soot particles enter the vortex zone and continue to maintain the original motion state to be captured, and the other part enters the opening. The opening channels of the orifice plate are captured, and all the captured particles are finally collected into the oil tank to achieve separation; the invention creates a vortex area through the spoiler, increases the capture rate of oil fume particles, and greatly improves the removal rate of oil fume particles on the order of 10 μm .

Description

technical field [0001] The invention relates to the technical field of high-efficiency capture of kitchen oil fume particles, in particular to a turbulent flow-type dynamic separation mesh disk used in the interior of a range hood. Background technique [0002] Kitchen oil fume contains a variety of toxic and harmful components, including a variety of mutagenic and carcinogenic substances, which have a great harmful effect on the atmospheric environment and human health. The problem is not only a simple environmental problem, but also a social problem. [0003] At present, an oil fume separation device is usually integrated inside the range hood to ensure that the internal working fan is not easily blocked by oil fume particles, resulting in reduced efficiency. According to the installation and operation conditions, the oil fume separation device can be divided into static type and dynamic type. In the past, the dynamic separation screen disk was usually captured in the fo...

Problems solved by technology

[0004] In the past, when the dynamic separation network disk improved the removal effect of oil fume particles, it would cause a large increase in pressure drop. In order to solve this contradictory problem, the purpose of the present invention is to provide a flow-disturbing dynamic separation network disk for the inside of the range hood. Create a small-scale complex flow area through the spoiler to increase the capture probability of oil fume particles. Since the small-scale complex flow area is not in the main flow area, a large increase in pressure drop is avoided. In addition, its processing and installation process are simple and easy to clean. According to numerical simulation The results show that the dynamic separation network disk of the present invention has a better separation effect on oil fume particles on the order of 10 μm compared with the perforated disk without spoiler baffles
