Detailed Description

The utility model relates to an air-conditioning filter capable of removing acid gas, which comprises an outer frame, wherein the outer frame is in a polygonal shape; the inner liner is arranged in the outer frame, and the shape of the inner liner is matched with that of the outer frame so as to enable the outer edge of the inner liner to be combined with the inner edge of the outer frame and be connected with the inner edge of the outer frame in a sealing mode; the lining layer comprises a plurality of non-woven fabric layers and at least one acid gas adsorption layer, and the at least one acid gas adsorption layer is arranged among the non-woven fabric layers; the acid gas adsorption layer comprises a carrier containing sodium bicarbonate, and the carrier is uniformly distributed in the acid gas adsorption layer. When the air is circulated, the sodium bicarbonate on the carrier can filter and absorb acid gas in the air.

Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 shows a perspective view of an air conditioner filter of the present embodiment. The air conditioner filter comprises an irregular outer frame 1 and an inner liner 2, wherein the outer frame 1 is pentagonal in appearance, and the inner liner 2 is arranged in the outer frame 1 in a corrugated shape. The outer frame 1 and the inner liner layer 2 are bonded by hot melt adhesive to ensure the sealing performance, so that gas is ensured to flow out after being filtered, and unfiltered gas flow cannot occur. Of course, the outer frame 1 and the inner liner 2 may be combined in other ways. The corrugations resemble the waves of a folding fan, but all maintain a substantially uniform shape to ensure uniform gas flow.

The following description will be given of exemplary embodiments, which do not constitute a limitation of the scope of the invention.

Example 1

Figure 2 shows an embodiment of a relatively basic inner liner 2. In this embodiment, the inner liner 2 includes two non-woven fabric layers made of water-absorbent nylon, i.e., a non-woven fabric layer one 3 and a non-woven fabric layer two 5, and an adsorption layer one 4 made of porous ceramic, which are disposed inside the outer frame 1. The first adsorption layer 4 is used for absorbing acid gas. The adsorption layer 4 is composed of a carrier containing sodium bicarbonate, such as activated carbon particles. The activated carbon particles have more irregular pore passages and large specific surface area, so that a large amount of sodium bicarbonate can be attached to the activated carbon particles to ensure strong adsorption capacity and long service life of the lining layer. The number of the activated carbon particles can be adjusted according to actual requirements. When air circulates, the sodium bicarbonate attached to the activated carbon particles can filter and absorb acid gases in the air, and the air purification effect is achieved.

Example 2

Figure 3 illustrates another embodiment of an inner liner. In this embodiment, the inner liner includes three nonwoven fabric layers, i.e., three nonwoven fabric layers 6, four nonwoven fabric layers 7, and five nonwoven fabric layers 8, and two absorbent layers, i.e., two absorbent layers 9 and three absorbent layers 10, disposed within the outer frame 1. The second adsorption layer 9 and the third adsorption layer 10 are respectively arranged between the third nonwoven fabric layer 6, the fourth nonwoven fabric layer 7 and the fifth nonwoven fabric layer 8. The three non-woven fabric layers are respectively made of water-absorbent nylon, terylene and polypropylene materials, but are not limited to the materials. The air is purified by passing through the third nonwoven fabric layer 6, the second absorbent layer 9, the fourth nonwoven fabric layer 7, the third absorbent layer 10 and the fifth nonwoven fabric layer 8 in this order.

The second adsorption layer 9 is composed of a carrier containing sodium bicarbonate. In this example, the support is silica particles. When air is circulated, the sodium bicarbonate attached to the silica particles can filter and absorb acid gases in the air.

The third adsorption layer 10 is a post-adsorption layer to remove harmful gases (formaldehyde, VOC, TVOC, etc.) and various microorganisms (bacteria, viruses, etc.), etc. to further purify the air or provide other functional effects. Specific substances can also be disposed in the carrier of the adsorption layer three 10, as the case may be.

Example 3

In example 3, one or more absorbent layers may be further disposed after the nonwoven fabric layer five 8 following the absorbent layer three 10 of example 2, as desired. The absorption layer can be a vitamin layer, a flavor release layer, or a mixed layer.

Example 4

In example 4, one or more other adsorption layers (not shown), such as a hair filter layer, can also be arranged in front of the non-woven fabric layer three 6 in example 2 according to production requirements. In example 4, a harmful gas adsorption layer and the like may be added before the second adsorption layer 9. In experiments, the inventor finds that the non-woven fabric layer three 6 of the second adsorption layer 9 needs to be compact and firm, and the pore size is appropriate, so as to ensure that the carrier in the adsorption layer which is arranged in front of the second adsorption layer 9 can be blocked by the non-woven fabric layer three 6, namely, impurities or the carrier in the previous layer cannot be blown into the adsorption layer along with air.

In areas with high acid gas content, such as areas with acid rain prevalence, two acid gas adsorption layers may be provided to accommodate more sodium bicarbonate, or other basic compounds.

Example 5

The utility model discloses can also have the inner liner of 6 layers of adsorbed layers, be hair filter layer, acid gas adsorbed layer, alkaline gas adsorbed layer, nitrogenous waste gas adsorbed layer, organic matter adsorbed layer, fragrant smell release layer respectively. More adsorbent layers may also be added. However, in practice, it has been found that an excessive number of layers leads to a significant reduction in the flowability of the air.

The outer frame can be integrally formed or spliced. The shape of the frame can be pentagonal, and can also be other regular and irregular shapes, such as rectangular or polygonal and the like, as long as the outer frame can be matched with a proper accessory, so that the installation is convenient.

The acid gas adsorption layer comprises a carrier, and the carrier can be one or more of activated carbon particles, silica particles, molecular sieves, quartz sand or porous ceramics. The carrier has a plurality of pores in its internal structure. Preferred supports have a high specific surface area, a large pore volume, uniform pore size, so that as much sodium bicarbonate as possible is uniformly attached to the surface of the body and stored in the support. The surface and/or inside of the carrier may be attached with sodium bicarbonate by various methods, such as spraying an alkaline solution onto the carrier, or immersing the carrier in an alkaline solution.

Since the alkaline solution is to be attached to the support, the support is preferably a porous ceramic. The porous ceramic material is prepared by taking high-quality raw materials such as corundum, silicon carbide, cordierite and the like as main materials through molding and a special high-temperature sintering process, has the characteristics of high temperature resistance, high pressure resistance, acid resistance, alkali resistance, organic medium corrosion resistance and the like, and has the advantages of good biological inertia, controllable pore structure, high open porosity, long service life, good product regeneration performance and the like. Therefore, the porous ceramic is very suitable for carrying acidic substances, or basic substances, for purifying air.

Preferably, other basic compounds, such as sodium hydroxide and the like, are also effective in removing acid gases. For safety reasons, the present invention is preferably sodium bicarbonate, i.e. baking soda can be used. Other more basic compounds may cause harm to the manufacturing workers. In addition, the weak alkalinity of sodium bicarbonate is safe for the user. Under the weak base environment, the bacterium breeds and breeds more difficultly, consequently makes this air filtration material with sodium bicarbonate (weak base) can have sterilization and bacteriostatic action, and this air filtration material with sodium bicarbonate can with the acid gas in the air, produces neutralization reaction, effectively purifies the environment.

The efficiency of the air conditioner filter for removing acid gas is closely related to the amount of sodium bicarbonate added. The higher the amount of sodium bicarbonate added, the less the content of acidic gases that flow through the air conditioning filter and the cleaner the air obtained. Therefore, a plurality of functional layers of sodium bicarbonate may also be added. It should be noted, however, that the greater the number of layers of the functional layer, the better the cleaning effect, but at the same time the greater the resistance to the air circulating, and therefore the greater the energy consumed for blowing. Therefore, there is a need to balance the purification effect and the resistance to air flow, and to ensure that air passing through the filter is both purified and that the air conditioning filter does not create excessive resistance to air.
