Next, with reference to the drawings, an air treatment apparatus 1000 according to an embodiment of the present invention is described.

As shown in fig. 1, an air treatment apparatus 1000 according to an embodiment of the present invention includes: a housing 100 and a fan 200. The casing 100 is provided with an air inlet 101 and an air outlet 102, the casing 100 is internally provided with an air duct 103 communicating the air inlet 101 and the air outlet 102, and the fan 200 is arranged on the air duct 103 and used for ventilating the air duct 103. Thus, the air processing device 1000 is provided with a ventilation function, for example, by operating the fan 200, air in the environment of the air processing device 1000 can be sucked from the air inlet 101, and then the air can be sent back to the environment of the air processing device 1000 through the air outlet 102, and the air flow on the flow path can be processed by the processing components inside and/or outside the casing 100, so as to realize the air processing function. The setting position and the configuration of the processing component are not limited, for example, the processing component may only include the processing module 300 described later, and for example, the processing component may also include other processing modules, such as the heat exchange module 400 and the humidification module, while including the processing module 300 described later, which are not described herein again.

As shown in fig. 1, the air treatment apparatus 1000 according to an embodiment of the present invention may further include: 2-4, the processing module 300 includes a reaction box 1 and a processing assembly, the processing assembly is disposed in the reaction box 1, the reaction box 1 has an air inlet 11 and an air outlet 12, and the air inlet 11 and the air outlet 12 are sequentially arranged on an airflow path from the air inlet 101 to the air outlet 102, so that the airflow enters the reaction box 1 through the air inlet 11 and flows out of the reaction box 1 through the air outlet 12 under the action of the fan 200. The processing module 300 is disposed at least one of the air duct 103, the air inlet 101, and the air outlet 102. That is, at least one of the positions of the inside and/or outside at the intake opening 101, the inside and/or outside at the outlet opening 102, and the air duct 103 is provided with the process module 300.

Specifically, the processing module 300 may be disposed inside and/or outside the housing 100, or a portion of the processing module 300 may be disposed inside the housing 100, and a portion of the processing module 300 may extend out of the housing 100, the processing module 300 disposed inside the housing 100 may be disposed inside the air duct 103, the processing module 300 disposed outside the housing 100 may be disposed at the air outlet 102 and/or the air inlet 101, and the processing module 300 may be disposed by matching the orientations of the air inlet 11 and the air outlet 12 of the reaction box 1, so that the processing module 300 may be operated by the fan 200, and the processing module 300 may also ventilate, thereby simplifying the structure of the processing module 300, so that the processing module 300 does not need to separately dispose a ventilation device, reducing the cost of the processing module 300, and improving the structural compactness of the processing module 300.

For example, when the processing module 300 is disposed in the air duct 103 of the housing 100 and near the air inlet 101 (as shown in fig. 1), when the blower 200 is operated, the air flow outside the housing 100 enters the air duct 103 from the air inlet 101, and a part of the air flow enters the reaction cassette 1 through the air inlet 11 and then exits the reaction cassette 1 through the air outlet 12, flows to the air outlet 102 along with other air flows in the air duct 103, and is sent out of the housing 100 through the air outlet 102. For another example, when the processing module 300 is disposed in the air duct 103 of the housing 100 and near the air outlet 102 (not shown in this example), when the blower 200 is operated, the air flow outside the housing 100 enters the air duct 103 from the air inlet 101 and flows toward the air outlet 102, a part of the air flow flowing to the air outlet 102 is directly sent out through the air outlet 102, and another part of the air flow enters the reaction cassette 1 through the air inlet 11 and then flows out of the reaction cassette 1 through the air outlet 12 and then is directly sent out of the housing 100, or is sent out of the housing 100 through the air outlet 102.

Of course, the invention is not limited thereto, and the processing module 300 may be disposed in the middle of the air duct 103 or other positions. In addition, the processing modules 300 may be disposed at least two of the air duct 103, the air inlet 101, and the air outlet 102, so as to improve the overall processing effect of the processing modules 300.

Furthermore, it should be noted that the area of the air inlet 11 or the air outlet 12 of the process module 300 may be smaller than or equal to the flow area of the position where the air inlet 11 or the air outlet 12 is located, for example, when the process module 300 is located at the air inlet 101, the area of the air inlet 11 may be smaller than or equal to the area of the air inlet 101, and for example, when the process module 300 is located at the air outlet 102, the area of the air outlet 12 may be smaller than or equal to the area of the air outlet 102. These can be designed according to practical requirements, and are not limited herein.

In an embodiment of the present invention, as shown in fig. 3 and 4, the processing components of the processing module 300 may include: ultraviolet lamp 2, infrared lamp 3 and catalysis piece 4 form reaction channel 13 between ultraviolet lamp 2, infrared lamp 3 and the catalysis piece 4, and reaction channel 13 intercommunication is between air inlet 11 and gas outlet 12, and ultraviolet lamp 2, infrared lamp 3 and catalysis piece 4 all reveal in reaction channel 13. From this, ultraviolet lamp 2 and infrared lamp 3 all can all irradiate reaction channel 13, and ultraviolet lamp 2 and infrared lamp 3 still all can be to 4 irradiations of catalysis spare, in order to produce thermal catalysis and photocatalysis to catalysis spare 4 respectively, thereby by the air current of air inlet 11 entering reaction channel 13, can be by ultraviolet lamp 2, infrared lamp 3, and catalysis spare 4 handles, thereby play effectual coprocessing effect, thereby can reduce the temperature in catalysis spare 4 and the reaction box 1, reduce the temperature rise of the outer environment of reaction box 1, be favorable to being applied to in air treatment equipment 1000, avoid the environmental temperature rise that processing module 300 caused, cause harmful effects to air treatment equipment 1000's normal work.

For example, when polluted air containing bacteria and peculiar smell enters the reaction channel 13 in the reaction box 1 through the air inlet 11, the infrared lamp 3 and the ultraviolet lamp 2 are started, on one hand, irradiation on the reaction channel 13 is realized, and microorganisms in the polluted air are subjected to the combined action of infrared heating and ultraviolet irradiation in the reaction channel 13 simultaneously, so that the proteins and physiological active substances in the microorganisms are changed, and the microorganisms are killed to achieve the bactericidal effect. And through opening infrared lamp 3 and ultraviolet lamp 2, on the other hand can realize the radiation thermal catalysis and the photocatalysis to catalysis piece 4, through the thermal synergy and the light synergism of catalysis piece 4, can strengthen the microorganism and kill to can effectively get rid of the air peculiar smell pollution, and can effectively reduce the temperature in catalysis piece 4 and the reaction box 1. If tests prove that under proper conditions, the killing rate of staphylococcus albus, staphylococcus aureus, escherichia coli, bacillus subtilis and other bacteria is greater than 99%, the removal rate of formaldehyde, acetic acid, trimethylamine, ammonia, toluene and other indoor odor pollutants is greater than 99%, the temperature inside the reaction box 1 can be kept at 20-300 ℃, but the environmental temperature outside the treatment module 300 is relatively low, and the temperature rise can be less than 5 ℃.

Some household devices in the related art, such as air conditioners or air purifiers, have sterilization and disinfection processing modules to improve indoor air quality, but these conventional processing modules have a problem that the processing effect is not ideal. The industrial thermal catalytic oxidation sterilization method has good treatment effect, but is limited by heating modes, environmental temperature requirements and the like, and cannot be applied to household equipment. In the processing module 300 of the embodiment of the present invention, the infrared ray can realize temperature rise of the catalytic element 4, so as to realize a thermocatalysis effect, and the activation energy is effectively reduced by the aid of the ultraviolet ray, and compared with the conventional thermocatalysis, the processing module can effectively reduce the reaction temperature, so as to reduce the temperature in the reaction box 1 and the catalytic element 4, so as to reduce the influence on the devices around the processing module 300, and is suitable for household equipment, such as an air conditioner or an air purifier.

It should be noted that, the specific type of the air processing apparatus 1000 according to the embodiment of the present invention is not limited, and for example, the air processing apparatus 1000 may be an air conditioner or an air purifier, and when the air processing apparatus 1000 is an air conditioner, the air processing apparatus 1000 may further include a heat exchanging module 400, and when the air processing apparatus 1000 is an air purifier, the air processing apparatus 1000 may further include other purification and disinfection modules, and the like.

Alternatively, the process modules 300 may be received in the air duct 103 inside the housing 100 and installed near the air inlet 101 or the air outlet 102, so that the process modules 300 may be protected by the housing 100 on one hand and the installation and the removal of the process modules 300 may be facilitated on the other hand.

In some embodiments of the present invention, as shown in fig. 3, the processing module 300 may further include: and the heat insulation layer 5 is arranged on the wall surface of the reaction box 1 and avoids the air inlet 11 and the air outlet 12. Thereby, the environmental temperature rise caused by the process module 300 can be further reduced, thereby improving the adaptability of the process module 300 to the air treatment device 1000.

It should be noted that, the specific structure of the heat insulation layer 5 is not limited, for example, the heat insulation layer 5 may be an aerogel heat insulation layer and is attached to the outer wall surface of the reaction box 1, so that the heat insulation effect of the heat insulation layer 5 is better and the installation is convenient. For example, in some specific examples, the main component of the thermal insulation layer 5 may be SiO2, the thermal conductivity coefficient is 0.018w/mk (25 ℃), and the thermal insulation layer 5 is wrapped on the outer surface of the reaction box 1, so that the temperature of the reaction box 1 is reduced to normal temperature after passing through the thermal insulation layer 5, and the influence on the surrounding environment, devices and the like is small.

Optionally, the thickness of the insulation layer 5 is 3mm-10mm, for example, the thickness of the insulation layer 5 may be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc. Thus, the heat insulating layer 5 can exhibit a good heat insulating effect.

In some embodiments of the present invention, as shown in fig. 2 and 3, at least one of the gas inlet 11 and the gas outlet 12 is a ventilation opening 1420, and the reaction cassette 1 includes a ventilation cover 14 provided with the ventilation opening 1420, and the ventilation cover 14 defines a non-linear gas flow path 1410 communicating the ventilation opening 1420 with the reaction channel 13. Therefore, by arranging the nonlinear airflow channel 1410, a relatively effective shading effect can be achieved, adverse effects caused by leakage of ultraviolet light and infrared light are reduced, and smooth ventilation can be guaranteed.

For example, the air inlet 11 is a ventilation opening 1420, the reaction cassette 1 includes a ventilation cover 14 provided with the air inlet 11, the ventilation cover 14 defines a nonlinear air flow path 1410 communicating the air inlet 11 with the reaction channel 13, and the air flow outside the reaction cassette 1 can enter the air flow path 1410 through the air inlet 11 and then enter the reaction channel 13 through the air flow path 1410. Since the air flow path 1410 is non-linear, ultraviolet light, infrared light, and the like in the reaction channel 13 are difficult to pass through the air flow path 1410, and the probability of light leakage from the air inlet 11 is reduced.

For another example, the gas outlet 12 is a ventilation opening 1420, the reaction cassette 1 includes a ventilation cover 14 provided with the gas outlet 12, the ventilation cover 14 defines a nonlinear gas flow path 1410 communicating the gas outlet 12 with the reaction channel 13, and the gas flow inside the reaction cassette 1 can first pass through the gas flow path 1410 and then flow out of the reaction cassette 1 from the gas outlet 12. Since the air flow channel 1410 is non-linear, ultraviolet light, infrared light, and the like in the reaction channel 13 are difficult to pass through the air flow channel 1410, and the probability of light leakage from the air outlet 12 is reduced.

For another example, the air inlet 11 and the air outlet 12 are both the ventilation openings 1420, and the reaction cassette 1 includes a ventilation cover 14 provided with the air inlet 11 and a ventilation cover 14 provided with the air outlet 12. Thereby, as described above, the probability of light leakage from the air outlet 12 and the air inlet 11 can be reduced.

It should be noted that the non-linear airflow channel 1410 is not limited, for example, in some specific examples, as shown in fig. 2 and 3, the vent cover plate 14 may include a plurality of baffles 141, the plurality of baffles 141 are spaced and staggered to define a zigzag airflow channel 1410, and the airflow channel 1410 communicates the vent 1420 with the reaction channel 13. Here, the "staggered arrangement" refers to a non-side-by-side arrangement, for example, when the plurality of baffles 141 are arranged at intervals in the first direction, two adjacent baffles 141 are staggered from each other in a second direction perpendicular to the first direction, for example, in the example shown in fig. 3, the first direction is a left-right direction, the second direction is an up-down direction, one of the two adjacent baffles 141 is above and the other is below, so as to be staggered from each other, the air flow can bypass from the upper end of the baffle 141 below, then flow through the gap between the two baffles 141, and bypass from the lower end of the baffle 141 above, so as to realize the flow, and the light inside the reaction cassette 1 is difficult to bypass the plurality of baffles 141 through the broken line path. From this, through setting up a plurality of baffles 141 interval and crisscross setting, can play comparatively effectual shading effect, reduce the harmful effects that ultraviolet ray, infrared light leaked and caused, and can guarantee to ventilate smoothly.

Or in some other specific examples, the ventilation cover plate 14 may include a plurality of hole plates arranged at intervals, and the ventilation holes on two adjacent hole plates are arranged alternately, that is, the ventilation holes on two adjacent hole plates are not arranged right opposite to each other, so that after the air flow passes through the ventilation hole on one hole plate, the air flow can enter between the two hole plates and then flow out through the ventilation hole on the other hole plate, thereby realizing circulation, and the light in the reaction box 1 is difficult to flow out through the ventilation holes on the plurality of hole plates through a broken line path. From this, through setting up the crisscross setting of a plurality of orifice plate intervals and air vent, can play comparatively effectual shading effect, reduce the harmful effects that ultraviolet light, infrared light leaked and caused, and can guarantee to ventilate smoothly.

In some embodiments of the present invention, as shown in fig. 2 and 3, vent flap 14 includes panel 142, vent openings 1420 are formed in panel 142, and panel 142 defines transition passage 143, transition passage 143 tapering in cross-section in a direction from reaction channel 13 to vent openings 1420. Thus, when the air inlet 11 is the ventilation opening 1420, the air flow entering the air inlet 11 from the outside of the reaction cassette 1 is decelerated through the transition passage 143, so that the air flow can be more sufficiently processed inside the reaction cassette 1. When the air outlet 12 is the air vent 1420, the air flow speed is increased when the air flow flows out from the air outlet 12 through the transition passage 143 from the inside of the reaction box 1, thereby ensuring concentrated air outlet and long air supply distance.

In some embodiments of the present invention, as shown in fig. 3, the processing module 300 may further include: the temperature sensing element 6 is used for monitoring the temperature of the catalytic element 4; the air treatment apparatus 1000 further comprises a controller, which is connected to the temperature sensing member 6 and the infrared lamp 3, respectively, to control the on/off of the infrared lamp 3 by the monitoring data of the temperature sensing member 6. From this, can avoid the catalysis piece 4 high temperature, the high temperature in the reaction box 1 causes the too high problem of reaction box 1 surrounding environment temperature rise, for example, can be when the temperature of catalysis piece 4 reaches the predetermined value, close infrared lamp 3 to guarantee that reaction box 1 surrounding environment temperature rise is lower, make processing module 300 good to air treatment facilities 1000's suitability. For example, the infrared lamp 3 may be intermittently turned on, and the ultraviolet lamp 2 may be normally turned on.

The controller may be disposed at any position, for example, outside the reaction cassette 1 without being connected to the reaction cassette 1, outside the reaction cassette 1 and attached to the reaction cassette 1, inside the reaction cassette 1, or the like, and is not limited thereto. In addition, it should be noted that the specific choice of the temperature sensing element 6 is not limited, for example, in some specific examples, the temperature measuring range of the temperature sensing element 6 may be 10 ℃ to 500 ℃, the accuracy is 0.1 ℃, and the temperature sensing element is a contact temperature sensor, such as a thermocouple temperature sensor. Therefore, the temperature sensing element 6 is arranged to monitor the surface temperature of the catalytic element 4 in real time, and the infrared lamp 3 is controlled and adjusted to be turned off and on by an external controller, so that the surface of the catalytic element 4 is maintained at a proper temperature.

In some embodiments of the present invention, as shown in fig. 3 and 4, the catalytic member 4 has a plate shape, i.e. the length and width are both much larger than the thickness, and one ultraviolet lamp 2 and one infrared lamp 3 are a group of reaction lamps, and the ultraviolet lamp 2 and the infrared lamp 3 in each group of reaction lamps are both arranged on the same side of the thickness of the catalytic member 4. The "plate shape" may be a flat plate shape, but is not limited to a flat plate shape, and may also be a broken line plate shape, a curved surface plate shape, or the like.

Therefore, when the air flow passes through the reaction channel 13 defined between the grouped reaction lamps and the catalytic piece 4, the air flow can be fully processed by the reaction lamps and the catalytic piece 4, the processing effect is improved, the temperature in the catalytic piece 4 and the reaction box 1 can be reduced, and the temperature rise of the reaction box 1 to the ambient environment is reduced. Alternatively, in some embodiments, as shown in fig. 3 and 4, at least one set of reaction lamps is provided on each of both sides of the thickness of the catalytic member 4. This makes it possible to sufficiently utilize the catalyst 4 and improve the treatment efficiency.

In some embodiments of the present invention, as shown in fig. 2 to 4, the air inlet 11 and the air outlet 12 are respectively located at both sides of the reaction cassette 1 in the width direction F1, the catalytic member 4 extends along a folding line or a wavy line in the length direction F2 of the reaction cassette 1, the ultraviolet lamps 2 and the infrared lamps 3 in each group of reaction lamps are spaced apart in the width direction F1 of the reaction cassette 1, and both the ultraviolet lamps 2 and the infrared lamps 3 extend in the length direction F2 of the reaction cassette 1. From this, ventilation resistance is little, and it is smooth and easy to ventilate, and the air volume is great, and the treatment effeciency is higher, and the treatment element can be make full use of. And simple structure, be convenient for assembly and dismantlement do not have mutual interference between each part, and it is effectual in coordination.

For example, as shown in fig. 2-4, the reaction cassette 1 may be a hexahedron and includes two ventilation cover plates 14 disposed opposite to each other in the width direction F1, a top wall 15 and a bottom wall 16 disposed opposite to each other in the height direction F3, and two side walls 17 disposed opposite to each other in the length direction F2, one ventilation cover plate 14 is provided with an air inlet 11, the other ventilation cover plate 14 is provided with an air outlet 12, the catalytic member 4 is disposed at a distance between the top wall 15 and the bottom wall 16, and both ends of the catalytic member 4 are supported on mounting seats 18 in the two side walls 17, the inner surface of the top wall 15 and the inner surface of the bottom wall 16 are each provided with a group of reaction lamps, that is, the lower surface of the top wall 15 is provided with one ultraviolet lamp 2 and one infrared lamp 3, and the upper surface of the bottom wall 16 is provided with one ultraviolet lamp 2 and one infrared lamp 3. From this, it is smooth and easy to ventilate, and the air volume is great, and the treatment effeciency is higher, and the treatment element can be make full use of. And simple structure, be convenient for assembly and dismantlement do not have mutual interference between each part, and it is effectual in coordination.

The number and the type of the ultraviolet lamps 2 are not limited. For example, in some embodiments of the present invention, the processing module 300 comprises two ultraviolet lamps 2, wherein one of the ultraviolet lamps 2 has a wavelength of 100nm to 200nm, such as 185nm, etc., so as to have a better ozone deodorization effect, and the other ultraviolet lamp 2 has a wavelength of 200nm to 280nm, such as 254nm, etc., so as to have a better sterilization effect. For example, the ultraviolet lamp 2 having a wavelength of 185nm can be accompanied by ozone to perform both deodorization and sterilization, thereby achieving more effective sterilization and deodorization effects. In addition, the high-temperature environment created by the infrared rays and the cooperation of the catalytic element 4 can effectively degrade the ozone associated with 185nm ultraviolet rays and prevent the ozone from escaping.

The structure of the catalyst member 4 is not limited. For example, in some embodiments of the invention, the catalytic member 4 comprises a support layer and a catalytically active layer, the catalytically active layer is disposed on each side of the thickness of the support layer, and the catalytically active layer comprises at least one of manganese titanium mixed oxide modified porous alumina, manganese titanium mixed oxide modified molecular sieve, manganese zinc mixed oxide modified porous alumina. From this, catalytic component 4's simple structure, thickness both sides can all be comparatively effectual with ultraviolet lamp 2 and infrared lamp 3 in coordination, exert better air treatment effect.

For example, the catalytically active layer may be a manganese-titanium mixed oxide modified porous alumina layer, or a manganese-titanium mixed oxide modified molecular sieve layer, or a manganese-zinc mixed oxide modified porous alumina layer, or the like.

Alternatively, the thickness of the catalytically active layer may be 4mm to 10mm, for example, the thickness of the catalytically active layer may be 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc., so that it may be more effective to exert a better air treatment effect in cooperation with the ultraviolet lamp 2 and the infrared lamp 3.

Along with the improvement of the household quality requirement and the enhancement of the health consciousness of people, environmental microorganism and peculiar smell pollution are gradually concerned by people. At present, the technology and the device for removing microorganisms and peculiar smell in the indoor environment are also diversified. For example, common negative ion sterilization, positive and negative ion sterilization, plasma sterilization, hot air sterilization, UVC (wavelength is 200-275 nm, also called short wave sterilization ultraviolet) sterilization, silver ion coating sterilization, ozone sterilization, electrolytic saline sterilization and the like, wherein the negative ions, the positive and negative ions and the plasma are beneficial to enrichment and sedimentation of microorganisms so as to reduce the content of space microorganisms, and the bacteria cannot be killed efficiently and quickly. UVC, ozone, and electrolyzed brine have good killing effects, but are often limited due to the risk of light irradiation and escape of active substances, such as ozone, hypochlorous acid, and the like. Moreover, the sterilizing effect is better under the static state of UVC, but under the condition of higher wind speed, the efficiency of killing air is relatively insufficient.

In the aspect of removing the peculiar smell, activated carbon adsorption is generally adopted, but the peculiar smell in the household environment is diversified, and the smell threshold value is extremely low, so that the problem of peculiar smell pollution cannot be well solved by the activated carbon adsorption method. In addition, some normal temperature catalysis methods such as UV (ultraviolet) photocatalysis, DBD plasma catalysis and the like exist at present, and the methods have pertinence and cannot remove a plurality of peculiar smells in a broad spectrum. In addition, although the thermal catalytic oxidation has a strong broad spectrum on volatile organic compounds, for example, catalytic combustion is mostly adopted in industry to treat volatile organic compound pollution, and the treatment is thorough, but the thermal catalytic oxidation is limited by a heating mode, environmental temperature requirements and the like in the using process, and cannot be popularized and used in a household environment.

Aiming at the technical problems, the invention aims to provide a high-efficiency, feasible and safe deodorizing and sterilizing scheme which can be applied to a household environment. The applicant finds that the UV irradiation can not only effectively kill bacteria, but also be combined with a photocatalyst for degrading and removing partial gaseous pollutants, but the broad spectrum and the efficiency are still required to be enhanced, for example, when the UV irradiation is used for removing odor, the UV irradiation has a good decomposition effect on a small amount of odor substances, such as formaldehyde, but has a poor removal effect on partial odor substances, such as acetic acid and the like. Furthermore, to prevent UV leakage, a closed design is often used, which is effective only for leakage under 254nm light irradiation, but still cannot effectively solve the problem of 185nm UV-associated ozone dissipation. If the technology can be further improved, the effects of high-efficiency sterilization, high-efficiency deodorization can be realized.

Therefore, the present invention provides a processing module 300 for deodorizing and sterilizing by photo-thermal concerted catalysis, wherein the processing module 300 comprises: a heat insulation layer 5, a reaction box 1, an ultraviolet lamp 2, an infrared lamp 3, a catalytic element 4 and a temperature sensing element 6. The reaction box 1 is used for providing a reaction cavity for photo-thermal synergy, and the infrared lamp 3, the ultraviolet lamp 2 and the catalytic piece 4 are all arranged in the reaction box 1.

The ultraviolet lamps 2 can be provided with two ultraviolet lamps, one ultraviolet lamp has a wavelength of 185nm and is accompanied with ozone for removing odor and sterilizing, the other ultraviolet lamp has a wavelength of 254nm for sterilizing, the working voltage is AC-220V, and the power is 50w-500w; for example, the power can be selected to be 200w, so that the sterilizing, deodorizing and photocatalytic effects can be better.

The catalyst member 4 may have a corrugated structure, and a carrier layer may be disposed in the middle, and may be a light aluminum foil, a copper foil, an aluminum alloy foil, a porous metal mesh, a metal woven mesh, or the like, and has a thickness of 20 μm to 2000 μm, for example, specifically, about 100 μm, and catalyst active layers are disposed on both sides of the thickness of the carrier layer, respectively, and may have a thickness of 4mm to 10mm, for example, specifically, 8mm. The catalyst active layer may be a Y-type molecular sieve modified with a Mn-Zn-Co mixed oxide, for example, specifically, a porous alumina modified with a manganese-titanium mixed oxide (which may be doped with other elements), a manganese-titanium mixed oxide (which may be doped with other elements) modified molecular sieve, a manganese-zinc mixed oxide (which may be doped with other elements) modified porous alumina, or the like. Therefore, the photo-thermal synergistic effect can be better.
