The adsorbent material includes porous materials such as activated carbon and zeolite, and its operation principle is to utilize the adsorbent material to adsorb (i.e. intercept) the particles in the gas, however, after the adsorption is saturated, the adsorbent material loses the adsorption effect, and the adsorbent material must be replaced. In addition, the adsorbent does not have an effect of removing organic substances and odor in the gas.

The catalyst material includes, for example, a photocatalyst, a thermal catalyst, etc., and the catalyst material operates on the principle of decomposing organic substances (e.g., formaldehyde, benzene, ammonia, bacteria, etc.) in the gas, fine particles, and odor in the gas by irradiating light or heating the catalyst.

Detailed Description

Referring to fig. 1, the present invention provides a gas cleaning composite material 1, which comprises a plurality of catalyst materials 10 in the form of particles and a plurality of adsorbing materials 20 in the form of particles. A plurality of granular catalyst materials 10 and a plurality of granular adsorbents 20 are mixed to form a gas cleaning composite 1. The particle sizes of the catalyst material 10 and the adsorbing material 20 are not limited, and may be, for example, in the range of 6 to 50 nanometers (nm). Alternatively, the surface area ratio of the catalyst material 10 to the adsorbent material 20 is between 500-2000 square meters per gram (m)²A range of/g).

The catalyst material 10 is used to generate a catalyst for decomposing organic substances in the gas. The catalyst material 10 is formed by coating a catalyst 12 on the surface of a substrate 11, and the thickness T of the catalyst 12 on the surface of the substrate 11 is equal to or less than 20 μm. Substrate 11 includes, but is not limited to, adsorbent materials, non-adsorbent materials. The catalyst 12 is not limited in kind, and may be, for example, a photocatalyst, a thermal catalyst, or another kind of catalyst capable of producing a catalytic action. Catalysts 12 include, but are not limited to, gold (Au), silver (Ag), photocatalyst (TiO)₂)。

The adsorbent 20 is used for adsorbing particles in the gas. The adsorbent 20 includes, but is not limited to, porous materials such as activated carbon and zeolite.

There is a particular relationship between the catalytic material 10 and the sorbent material 20. The total volume of the catalyst material 10 is A1, the total volume of the adsorbing material 20 is A2, and the ratio of A1 to A2 is 1: 6-1: 20.

The total weight of the catalyst 12 on the surface of the substrate 11 is W1, the total weight of the substrate 11 and the adsorbing material 20 is W2, and the ratio of W1/W2 is between 5% and 15%. The reason for the weight ratio is that, in some cases, the total volume of the catalytic material 10 and the adsorbent 20 cannot be measured specifically due to various factors, and therefore, whether the ratio of the catalyst is appropriate or not can be known by weight calculation.

It should be noted that, although the catalyst material 10 and the adsorbent 20 shown in fig. 1 are circular (or can be regarded as spherical), the present invention is not limited thereto. The catalytic material 10 and the adsorbent 20 may be the same or different particles of any geometric shape, regular or irregular, and the catalytic material 10 and the adsorbent 20 may be the same or different in size. Since the catalyst material 10 and the adsorbent 20 are in the form of particles, they are not arranged regularly as shown in fig. 1, and fig. 1 is only for explanation.

Please refer to fig. 2, which shows a gas cleaning composite module 2 having the gas cleaning composite material of fig. 1. The gas cleaning composite module 2 comprises a carrier 30, the carrier 30 has a plurality of supporting units 31, the carrier 30 has a plurality of holes 32, each supporting unit 31 is connected to a first surface 33 and a second surface 34 of the carrier 30 through the holes 32.

A gas cleaning composite 1 is disposed in each of the supporting units 32. The gas cleaning composite material 1 includes a catalyst material 10 and an adsorbent 20.

A catalyst module 40 is disposed on one side of the second surface 34 of the carrier 30 for generating a catalyst effect with the catalyst 12 on the surface of the substrate 11. The distance D between the catalytic module 40 and the catalytic module is equal to or less than 0.5 cm.

As mentioned above, the catalyst 12 shown in FIG. 1 can be a photocatalyst, a thermocatalyst, or other catalyst that can generate catalytic action, and thus the catalytic action module 40 includes, but is not limited to, an ultraviolet lamp, a heater. The catalyst 12 can be reused by the photocatalyst regeneration function of the ultraviolet lamp or the thermal catalyst regeneration function of the heater.

The position of the catalytic module 40 is not limited to that shown in fig. 2, and may be set above or below the carrier 30 as required, as long as ultraviolet rays or heat generated by the catalytic module 40 can act on the catalytic material 10.

When the gas G1 flows from the first surface 33 of the stage 30 into each of the carrier units 31 and passes through the gas cleaning composite material 1, harmful particles (e.g., PM2.5) in the gas G1 can be adsorbed by the adsorbent 20, and organic matters in the gas G can be decomposed by the action of the catalytic material 10 and the catalytic module 40, so that clean gas G2 flows out from the second surface 34 of the stage 30 opposite to the first surface 33.

The gas cleaning composite module 2 with the gas cleaning composite material provided by the utility model is provided with a plurality of bearing units 31, each bearing unit 31 can be uniformly filled with the granular gas cleaning composite material 1, however, in the embodiment, when the direction of gas G1 entering the gas cleaning composite module 2 is the horizontal direction, in addition, only one bearing unit 31 can be arranged, the principle is that the gas cleaning composite material 1 can be uniformly filled, the gas G1 can provide uniform adsorption filtration and catalyst filtration, and the catalyst 12 can be regenerated by using the catalyst action module 40.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the utility model as defined in the appended claims.
