Screw rod type wet-process oil smoke purification system

Abstract

The invention discloses a screw rod type wet-process oil smoke purification system. The system comprises a screw rod type machine head which is connected with a high-speed motor and communicates withan indoor oil smoke gas inlet, a liquid-gas separator filled with a washing liquid and used for carrying out separation between oil stain and gas on oil smoke, a washing liquid conveying device used for conveying the washing liquid into the machine head through high pressure, and a liquid-gas output pipe used for conveying oil gas from the machine head to the liquid-gas separator, wherein one endof the liquid-gas output pipe communicates with the machine head, and the other end of the liquid-gas output pipe communicates with the liquid-gas separator. According to the screw rod type wet-process oil smoke purification system, when the screw rod type machine head rotates and performs stirring at a high speed, the oil smoke is rapidly sucked in the machine head, and reaction, mixing and absorption are carried out so as to form a liquid-gas mixture, the liquid-gas mixture enters the liquid-gas separator from the liquid-gas output pipe, the oil stain and the washing liquid form a mixed solution, and the gas is discharged into the atmosphere. According to the screw rod type wet-process oil smoke purification system, the oil smoke, air and the washing liquid can be in full contact withoutbeing affected by the wind speed, so that the super-efficient purification effect is achieved, and the situation that the maintenance work such as pipeline oil dirt cleaning in a traditional smoke exhaust purification system must be carried out regularly is avoided.

Description

technical field [0001] The invention relates to an oil fume extraction system, in particular to a screw type wet oil fume purification system. Background technique [0002] With the rapid development of the country and around the world, environmental problems, especially air pollution, are becoming more and more serious. Oil fume in the catering industry has been recognized as the third major cause of smog. As early as a few years ago, the state promulgated mandatory administrative regulations, requiring that catering kitchens in large and medium cities must install oil fume purification devices that are certified by environmental protection. At present, the purification of cooking fume at home and abroad mainly includes the mechanical type of inertial collision, adsorption and filtration, the wet type of liquid film bubble, spray and impact, the electrostatic type of electrostatic adsorption and carbonization, the plasma type, the catalyst type and the composite type. At p...
