Oil fume treatment system combined with multi-chamber separation and centrifugal adsorption

Abstract

The invention provides a multi-chamber separation and centrifugal adsorption combined lampblack treatment system. The multi-chamber separation and centrifugal adsorption combined lampblack treatment system comprises a lampblack separator, a foam adsorber, a suction fan and a flue. The lampblack separator comprises a plurality of chambers which do not communicate with each other, and each chamber comprises a plurality of sub-chambers which communicate with each other. The suction fan and the foam adsorber are in coaxial linkage. The foam adsorber is made of porous foam metal and comprises a plurality of foam adsorption layers with different pore diameters. The rotational flow formed by the lampblack in each sub-chamber increases the contact time of the oil fume and the inner wall surface ofthe sub-chamber, and the centrifugal effect of the rotational flow enables viscous particles in the oil smoke to be smoothly adhered to the inner wall surface of the sub-chamber. The adsorption effect of the porous foam metal to particles is enhanced through the coaxial linkage of the foam adsorber and the suction fan. The foam adsorption layer with different pore diameters can realize gradient adsorption of large and small particulate matters in the lampblack. According to the lampblack treatment system, particulate matters with various particle sizes in the lampblack can be well removed byadopting a multi-way combined method.

Description

technical field [0001] The invention belongs to the technical field of range hoods, and relates to an oil fume treatment system combined with multi-chamber separation and centrifugal adsorption. Background technique [0002] According to research, the particle size distribution of the kitchen fume is widely distributed, and the concentration of the particles in the fume can be as high as dozens of times outdoors. However, the existing kitchen range hoods mainly rely on inertial collision devices such as metal mesh to remove large-size oil droplets in the lampblack. The collection rate is low, and the concentration of particulate matter discharged into the environment is high, causing serious environmental pollution. [0003] The oil fume separator used in some range hoods uses the centrifugal effect and adopts a high-speed rotating blade separator. This type of range hood only has a certain effect on large particles of oil droplets in the oil fume, but it often requires a h...

Problems solved by technology

In this device, when the radial velocity of the oil fume in the vertical pipe is too large, the effect of the swirling flow will be greatly reduced, and the device still has no separation effect on fine particles
