Wet type air adsorbing purifying device and method

Abstract

The invention provides a wet type air adsorbing purifying device and method. The device comprises a barrel, and the barrel is of a sealed structure. An adsorbing block is arranged in the barrel, the barrel is filled with eluant, and the adsorbing block is partially immersed in the eluant. An air inlet pipe is communicated with the barrel, and an air inlet of the air inlet pipe is located below the adsorbing block. An exhaust pipe is communicated with the barrel, and an exhaust opening of the exhaust pipe is located above the adsorbing block. The air inlet pipe or / and the exhaust pipe is / are provided with an air supply device. The height of the adsorbing block is regulated according to a pressure sensor so that the immersing line of the adsorbing block can be kept unchanged; by means of the steps, a continuous air purifying effect is achieved. The structure that the adsorbing block cooperates with the eluant is adopted, multiple purifying schemes of filtering, adsorbing and washing are integrated, and therefore cooking fume and the eluant can be fully mixed, then the cooking fume is adsorbed, and the cleaning effect is ensured. The device can further be used for circulating disinfection of indoor air besides cooking fume cleaning.

Description

technical field [0001] The invention relates to an air purification device, in particular to a wet air adsorption purification device. Background technique [0002] With the increasing prosperity of the catering industry, barbecue restaurants mainly engaged in kebabs, barbecue, and grilled chicken wings have gradually appeared in the city. They use coke and charcoal as fuel to generate a large amount of dusty oil fume The oil fumes in the air are mainly strong carcinogens such as polycyclic aromatic hydrocarbons and tar. At present, most catering industries install oil fume exhaust equipment to directly transfer the oil fume to the atmosphere. Although the air pollution in the kitchen can be alleviated to a certain extent, the pollutants in the oil fume cannot be removed, which brings serious pollution hazards to the atmosphere. In recent years, there have been many technologies for treating oily fume and exhaust gas at home and abroad, mainly in four categories: [0003] ...

AI Technical Summary

Problems solved by technology

[0003] (1) Inertial separation method: the dusty and oily fume passes through the grille or metal filter, the direction of the airflow changes, and the oil mist particles reach the deposition surface by inertia and are separated from the airflow. It is characterized by simple structure and small pressure drop. However, the purification efficiency is low, the workload of cleaning and maintenance is relatively large, and the cleaning is not timely and easy to block

[0004] (2) Electrostatic deposition method: Dust and oily flue gas passes through a high-voltage electric field, and the oil mist and dust particles are charged and move to the dust collecting electrode plate under the action of the electric field. The concentration of dust in the air is relatively high, and the dust and oily fumes will cause the corona electrode to fail in a short time

[0005] (3) Filtration method: When the dusty and oily fume passes through the polymer composite filter cloth, fiber pad or activated carbon fiber with high oil absorption performance, the oil mist will be purified due to gravity capture, etc., but it will be used in a short period of time. The adsorption material is saturated, and when the flue gas passes through again, it is like a piece of iron, the resistance is greatly increased, and the ventilation condition of the kitchen is seriously deteriorated

[0006] (4) Washing method: pass the absorption and purification liquid (water) through a special device to form a liquid film or liquid mist, so that the oil fume can fully contact with it, and wash and absorb the oil fume pollutants, but when the waste water is discharged into the sewer, there will be secondary pollution The problem

The above commonly used purification methods have their own characteristics, but also have their own limitations, such as high investment costs, difficult daily maintenance, low efficiency, and easy to produce secondary pollution, etc.
