detailed description

Below, a kind of mobile multifunctional air purifier of the present utility model is described in detail with reference to accompanying drawing and embodiment:

As shown in Figure 1, a mobile multifunctional air cleaner is a vertical rectangular structure, including a casing 1, casters 2 are arranged at the bottom of the casing, and an air inlet 3, Coarse filter 4 , axial flow fan 5 , adsorbent formed body assembly 6 , pre-filter 7 , fine filter 8 and air outlet 9 .

The above-mentioned coarse filter 4, axial flow fan 5, adsorbent forming body assembly 6, pre-filter 7, and fine filter 8 are installed in sequence with sealing rubber strips on each end surface between the two, and are compressed by locking screws or cams. , forming an airtight structure. The locking structure is easy to disassemble and assemble, and is convenient for maintenance and replacement of parts.

The air inlet 1 is supported by uprights welded by four sheet metal bending parts and connected with the main support uprights to form four air inlet surfaces. Since large particle aerosols in the air and harmful gases with a large specific gravity will settle under the action of gravity and accumulate near the ground, the bottom air intake structure can improve the filtration and adsorption efficiency of the filter.

As shown in Figure 2, the adsorbent shaped body assembly 6 includes a shaped body installation frame 10, in which a plurality of adsorbent shaped bodies 11 are arranged in a horizontal and staggered arrangement, forming a structure with high adsorption capacity and low pressure drop. The adsorption section constitutes one of the main functions of the air purifier.

As shown in Figures 3 and 4, the adsorbent forming body 11 is a multi-layer solid tubular structure. From the outside to the inside, it is the outer layer of the adsorption tube silk screen 12, the special particle adsorbent 13, the inner porous tube 14 and the activated carbon particles 15. Both ends of the shaped adsorbent body 11 are connected with circular plugs 16, the outer diameter of the plug 16 is 2S larger than that of the shaped adsorbent body 11, generally 2S = 0.5 mm ~ 5 mm, the best 2S = 1 ~ 2 mm, The gap between the shaped adsorbent body 11 and the plug 16 constitutes an air flow channel. The diameter of the adsorbent shaped body 11 is between 5 mm and 30 mm, and the optimum diameter is between 10 mm and 20 mm.

Among them, the outer wire mesh 12 of the adsorption tube and the inner porous tube 14 are made of metal mesh or polymer materials; the special particle adsorbent 13 is made of molecular sieve material, such as molecular sieve 13X, or molecular sieve 3A, 4A, 5A or molecular sieve ZSM-5 . The particle diameter of the special particle adsorbent 13 should be larger than the aperture of the outer layer wire mesh 12 and the inner porous tube 14 of the adsorption tube.

The coarse filter 4 is formed by stacking multiple layers of filter materials with larger apertures, preferably 2 to 3 layers, and the air inlet surface and the air outlet surface are compressed with metal perforated plates to form a complete coarse filter. The pre-filter 7 is composed of multi-layer filter materials with smaller apertures, preferably 2 to 3 layers, and the air inlet and outlet surfaces are compressed with metal perforated plates to form a complete pre-filter. The fine filter 8 is a folded plate and frame structure, and can be designed with various precisions according to different requirements.

A flow sensor (not shown) is installed in the air exhaust port 9 for air flow feedback, and the working pressure drop limit value of the fine filter 8 is set according to the function of the fine filter 8, and an alarm and replacement reminder for the fine filter is provided.

Working process of the present utility model:

The air enters the coarse filter 4 from the air inlet 3, and intercepts the dust particles with a particle size greater than 40 μm in the air. Then enter the axial flow fan 5 to obtain pressure and flow into the adsorbent forming body assembly 6. When the air flows through the special granular adsorbent 13 and activated carbon particles 15, due to diffusion and adsorption, the dust particles with a particle size of 0.3 to 40 μm in the air are adsorbed, Harmful impurities and odors are purified, and the pressure loss in this section is generally between 5 and 100Pa. Then the air flows through the pre-filter 7 to intercept particles with a diameter of 5-10 μm, and the pressure loss in this section is generally between 30-100 Pa. Finally, the air enters the fine filter 8. The fine filter 8 intercepts particles with a particle size above PM0.3, and the interception efficiency of particles larger than PM2.5 can reach 100%. The pressure loss in this section is generally between 200 and 350Pa. The purified air is discharged from the air outlet 9 to achieve the purpose of purifying the air.

The utility model has reasonable structure, good air purification effect, can purify various dusts and harmful gases above PM0.3, has small pressure loss, energy saving, long life, has the advantages of mobile multifunction, and is especially suitable for families, offices and those with special needs. occasions.
