Fully-dynamic centrifugal oil-gas-separation fume exhausting system for kitchen

Abstract

The invention discloses a fully-dynamic centrifugal oil-gas-separation smoke exhausting system for a kitchen. An oil-fume separator is mounted on a flue collection cover, wherein an outlet of the oil-fume separator is successively connected to a front electrostatic purifier and a rear photolysis purifier through an oil fume pipe; an outlet of the rear photolysis purifier is connected to an inlet of a fan; an outlet of the fan is connected to an exhausting pipe; the oil-fume separator comprises a mesh disc type oil-fume separation disc, a motor and an oil-fume separation cover; a cavity, an oil-fume inlet and an oil-fume outlet are formed in the oil-fume separation cover; the motor is axially arranged in the cavity; the mesh disc type oil-fume separation disc is mounted on a rotary shaft of the motor; the mesh disc type oil-fume separation disc comprises an upper metal wire mesh and a lower metal wire mesh which are formed by winding alloy filtration wires; an oil collection tank used for collecting oil thrown off by the mesh disc type oil-fume separation disc is arranged in the cavity. Due to the adoption of techniques such as centrifugal separation, flow collision and hydrophile-lipophile, the mesh disc type oil-fume separation disc rotates at high speed to form physical shielding; the adsorption area of oil drops is increased; the purification rate of the oil fume is improved.

Description

technical field [0001] The invention relates to a high-efficiency full-dynamic centrifugal oil-gas separation kitchen smoke exhaust system, which belongs to the technical field of kitchen smoke exhaust equipment. Background technique [0002] Oil fume is a mixed pollutant, a multiphase gaseous fluid containing gas, solid and liquid three-phase substances, there are as many as 200 to 300 kinds, including volatile nitrosamines, polycyclic aromatic hydrocarbons, nitroaromatics, hetero Known mutagens and strong carcinogens such as cyclic amine and tar. The traditional kitchen exhaust method is to discharge the oily fume in the kitchen directly to the window through the exhaust fan or the centralized exhaust pipe. Since the traditional range hood has no oily fume purification function, it relies on the exhaust air volume of the motor to exhaust the oily fume. The oily fume generally relies on the steady state The filter is used to filter, and the filtering and purification effec...

Problems solved by technology

The traditional kitchen exhaust method is to discharge the oily fume in the kitchen directly to the window through the exhaust fan or the centralized exhaust pipe. Since the traditional range hood has no oily fume purification function, it relies on the exhaust air volume of the motor to exhaust the oily fume. The oily fume generally relies on the steady state The filter is used to filter, and the filtering and purification effect is not good. The oil fume accumulates in the motor, wind wheel, exhaust pipe, and flue. , the direct emission of oil fume pollutes the outdoor atmosphere and increases the concentration of PM2.5 in the air

At the same time, part of the oil fume that has not been exhausted will remain in the kitchen, living room, and bedroom, seriously affecting people's health
