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

Embodiment 1

[0032] like figure 1 , 2 Among them, a kind of wet air adsorption purification device comprises cylinder body 19, and cylinder body is preferably cylindrical, and the top of cylinder body is provided with movable top cover, and cylinder body 19 and top cover form the structure of sealing, and cylinder body 19 is provided with The adsorption block 13, preferably, the adsorption block 13 is a porous structure. Examples are sponges or porous ceramics, but also blocks filled with activated carbon, such as cages 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% of low-foam cleaning agent, 2.5-3.5% of polyaluminum chloride, 3.5-5.5% of acetic acid %, alcohol 3~5%, and the balance is water. The low-foaming cleaning agent is a commercially available low-foaming water-based cleaning agent, which is compounded by various surfactants, penetrating agents and auxiliaries,

Embodiment 2

[0046] On the basis of embodiment 1, a kind of wet air adsorption purification method comprises the following steps:

[0047] 1. An adsorption block 13 that can be raised and lowered and whose edge forms a sliding seal with the inner wall of the cylinder is arranged in the cylinder body 19, and an eluent 15 is arranged in the cylinder body, and the adsorption block 13 is partially submerged 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 set above the adsorption block 13, and the height of the adsorption block 13 is adjusted through 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 to achieve continuous air purification effect.

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.
