Comprehensive oil smoke purifying device suitable for large and medium restaurants

Abstract

The invention discloses a comprehensive oil smoke purifying device suitable for large and medium restaurants, the comprehensive oil smoke purifying device comprises an oil smoke conveying mechanism, an oil smoke filtering and collecting mechanism and a condensing mechanism. The oil smoke purifying device uses water as a medium to purify oil smoke, has low cost and can be circulated; the low-temperature water is atomized and fully contacted with oil and gas to rapidly reduce the temperature of the oil and gas to purify and recycle the oil and gas so as to improve the oil smoke purification efficiency; surfactants are added into the condensed water, so that water molecules are fully mixed when contacting with oil molecules, and the oil removal efficiency is improved; an adsorption layer is arranged to adsorb oil in cooling water so as to improve the absorption amount of the oil molecules and facilitate cleaning and replacement in the future. Compared with the traditional oil smoke purification method, the comprehensive oil smoke purifying device has higher efficiency and better effect by adopting various methods to coordinate and purify the oil smoke.

Description

technical field [0001] The invention belongs to the technical field of kitchen oil fume purification equipment, and in particular relates to a comprehensive oil fume purification device suitable for large and medium-sized restaurants. Background technique [0002] Inhalation of lampblack into the human body will damage human immune function and easily cause lung cancer.

[0002] Inhalation of lampblack into the human body will damage human immune function and easily cause lung cancer. Moreover, lampblack will also accelerate the deterioration of the air environment and cause various environmental pollution. In addition, in places with a lot of lampblack, such as canteens and restaurants, , the fume may even cause a fire, bring safety hazards, and pose a threat to people's lives and property safety

At present, there are some purification technologies for kitchen fume exhaust gas at home and abroad. The commonly used methods are as follows, but they all inevitably have some shortcomings: (1) Filtration method: With the extension of operating time, the filter material is easy to block , the pressure drop increases, the filter material needs to be replaced or cleaned regularly, the maintenance is troublesome, and the operating cost is high. This method only has a purification effect on particulate matter, and it is difficult to remove gas pollutants; (2) Washing method: in the removal of solid and liquid pollutants At the same time, it also has a certain removal effect on the gaseous pollutants in the oil fume, but there are problems of low purification efficiency, and the equipment installation is cumbersome, and the water consumption is large. If the circulating absorption liquid is discharged directly without treatment, it will cause secondary pollution.

In addition, the absorption liquid circulation box is installed outdoors. In the northern region, the pipeline and box body need to be insulated, which increases the installation cost and manufacturing difficulty.

(3) Inertial separation method: This method has a high purification efficiency for large oil particles, but the removal rate for small particle sizes is low, usually 50% to 70%, and has no ability to remove odorous substances, and due to the viscosity of particles It is very large, and the cleaning and maintenance workload is relatively large, so the practical performance is poor
