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, f

Example Embodiment

[0031] Example 1:

[0032] Such as figure 1 , 2 Among them, a wet air adsorption and purification device includes a cylinder body 19, which is preferably cylindrical. The top of the cylinder body is provided with a movable top cover. The cylinder body 19 and the top cover form a sealed structure, and the cylinder body 19 is provided with The adsorption block 13, preferably, the adsorption block 13 is a porous structure. For example, sponge or porous ceramics can also be used as a block filled with activated carbon, such as a cage filled with block activated carbon.

[0033] The cylinder 19 is filled with an eluent 15, preferably the eluent 15 includes the following components by weight: 0.5~0.8% low foam cleaning agent, 2.5~3.5% polyaluminum chloride, 3.5~5.5 acetic acid %, 3~5% alcohol, the balance is water. Low-foaming cleaning agent is a commercially available low-foaming water-based cleaning agent, which is compounded by a variety of surfactants, penetrants and auxiliary agen...

Example Embodiment

[0045] Example 2:

[0046] On the basis of Example 1, a wet air adsorption purification method includes the following steps:

[0047] 1. An adsorption block 13 that can be raised and lowered and the edge and the inner wall of the cylinder form a sliding seal is arranged in the cylinder body 19, and an eluent 15 is set in the cylinder body, and the adsorption block 13 is partially immersed in the eluent 15;

[0048] 2. Use the air supply device to make air enter the eluent 15 and pass through the adsorption block 13 to purify the air;

[0049] 3. A pressure sensor 10 is arranged above the adsorption block 13, and the height of the adsorption block 13 is adjusted by a lifting device according to the pressure sensor 10, so that the immersion line 14 of the adsorption block 13 in the eluent 15 remains unchanged;

[0050] Through the above steps, a continuous air purification effect is achieved.

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] ...
