Description

Technical Field

[0001] The invention belongs to the technical field of air purification devices, in particular to a photocatalyst nano-decomposition deodorizing device. Background Art

[0002] Photocatalyst is a general term for optical semiconductor materials with photocatalytic functions, represented by nano-scale titanium dioxide. It is coated on the surface of the substrate and produces a strong catalytic degradation function under the action of ultraviolet light: it can effectively degrade toxic and harmful gases in the air; it can effectively kill a variety of bacteria, and can decompose and harmlessly treat toxins released by bacteria or fungi; it also has the functions of deodorization, anti-fouling, and air purification.

[0003] A Chinese patent with publication number CN209501360U discloses a photocatalyst deodorizing device, comprising a lower shell body with an open upper end and an upper cover sealed above the open end of the lower shell body; the interior of the lower shell body is divided into an air inlet area and a purification area by a partition; the lower end of the partition is fixed to the lower shell body, and a gap is left between the upper end and the upper cover; an air inlet is provided at the bottom of the air inlet area; an exhaust port is provided on the end surface of the purification area away from the air inlet area; an ultraviolet light source and a filtering mechanism are provided in the purification area; the ultraviolet light source is arranged close to the partition board and the lower end is fixed to the lower part of the purification area through a base; the ultraviolet light source emits light toward the filtering mechanism; the upper and lower ends of the filtering mechanism are respectively fixed to the upper cover and the purification area; the filtering mechanism comprises a photocatalytic filter plate, a collecting filter plate and an activated carbon filter plate which are arranged in sequence from the air inlet area toward the purification area.

[0004] In the current existing technology, although air can be decomposed when passing through the photocatalytic filter plate, the thickness of the photocatalytic filter plate is limited after all, which makes it difficult for a large part of the harmful gases in the air to be fully photocatalytically decomposed and discharged when the air passes through the photocatalytic filter plate quickly, resulting in a poor deodorization effect; and the temperature of the gas is different. When high-temperature gas or low-temperature gas passes through the photocatalytic filter plate, the photocatalytic activity is relatively low, which will lead to a decrease in the catalytic effect.

[0040] When the exhaust gas is purified, the one-way air inlet valve 22 needs to be opened, and the exhaust gas enters the housing 1 through the air inlet pipe 2. When the exhaust gas passes through the housing 1, it will pass through the dustproof plate 36, the silica gel filter plate 13, the heating plate 14, the photocatalytic filter plate 43 and the activated carbon plate 15 in sequence. The large particles of impurities in the exhaust gas will be filtered through the dustproof plate 36, and the large particles of impurities will be filtered into the collection pipe 3; the moisture in the exhaust gas will be filtered through the silica gel filter plate 13, and excessive humidity may cause the catalyst surface to adsorb too much moisture, hindering the adsorption and reaction of harmful gases; the temperature of the exhaust gas will be adjusted through the heating plate 14, so that the exhaust gas is adjusted to a suitable temperature, so as to improve the catalytic effect; the exhaust gas will be photolyzed through the photocatalytic filter plate 43 to decompose part of the harmful gas, and then under the action of the ultraviolet lamp 46 and the photocatalyst coating, part of the harmful gas will be further decomposed, and finally the exhaust gas will continue to decompose part of the harmful gas through the photocatalytic filter plate 43, and finally pass through the activated carbon plate 15, and adsorb part of the harmful gas through the activated carbon plate 15, so as to achieve the purpose of deodorization, and finally be discharged from the exhaust port 16;

[0041] When the auxiliary mechanism provided by the present invention is in use, by turning on the second motor 4, the second motor 4 drives the transmission shaft 41 to rotate through the output shaft, and drives the partition 44, the rotating drum 42 and the photocatalytic filter plate 43 to rotate through the transmission shaft 41, thereby increasing the contact area between the exhaust gas and the photocatalyst coating, and at the same time turning on the ultraviolet lamp 46, the photocatalyst coating produces active oxygen under the action of the ultraviolet lamp 46, and oxidizes and decomposes harmful gases in the air into carbon dioxide and water, so that the exhaust gas is fully catalyzed, thereby realizing the function of exhaust gas being discharged after being fully photocatalytically decomposed.

[0042] like Figure 2 and Figure 4 As shown, a connecting plate 31 is fixedly connected to the inner wall of the bottom end of the casing 1, a first motor 32 is fixedly connected to the bottom of the connecting plate 31, an output shaft of the first motor 32 is fixedly connected to a rotating shaft 33, the rotating shaft 33 is rotatably connected to a dustproof plate 36 through a bearing, and extends to the bottom of the dustproof plate 36; an impeller 35 is fixedly connected to the rotating shaft 33, and the impeller 35 is arranged above the dustproof plate 36.

[0043] The impeller 35 provided by the present invention is used to accelerate the flow of exhaust gas when in use. By turning on the first motor 32, the first motor 32 drives the rotating shaft 33 to rotate through the output shaft, and the rotating shaft 33 drives the impeller 35 to rotate. The exhaust gas is quickly absorbed by the impeller 35, thereby improving the efficiency of exhaust gas treatment.

[0044] like Figure 4 As shown, a scraper rod 34 is fixedly connected to the bottom of the rotating shaft 33 , and the scraper rod 34 is in close contact with the bottom of the dustproof plate 36 .

[0045] The scraper rod 34 provided by the present invention is used to clean the dust on the dustproof plate 36 when in use. When the dustproof plate 36 filters large particles of impurities, impurities will accumulate on the surface after a period of time, thereby blocking the dustproof plate 36 and affecting the flow of exhaust gas. When the rotating shaft 33 rotates, it will also drive the scraper rod 34 to rotate. The scraper rod 34 cleans the impurities on the surface and drops them into the collecting pipe 3, preventing the impurities from accumulating at the bottom of the dustproof plate 36, thereby achieving the function of cleaning the dust on the dustproof plate 36.

[0046] like Figure 2 As shown, a temperature sensor 38 and a humidity sensor 39 are fixedly connected to the two side walls of the connecting plate 31 respectively; the temperature sensor 38 is electrically connected to the heating plate 14, and a plurality of exhaust holes 141 are opened on the heating plate 14, and the exhaust holes 141 are set as curved holes.

[0047] When the heating plate 14 provided by the present invention is in use, the temperature and humidity of the exhaust gas are monitored respectively by the temperature sensor 38 and the humidity sensor 39. When the temperature is lower than the activity of the catalyst, the heating plate 14 is energized under the control of the temperature sensor 38. A plurality of exhaust holes 141 are provided on the heating plate 14, and the exhaust holes 141 are arranged as curved holes, so as to increase the heating time of the exhaust gas, so that the exhaust gas is heated to a suitable temperature and then flows to the photocatalytic filter plate 43 for catalytic adsorption.

[0048] like Figure 3 As shown, a fan 45 is fixedly mounted on the lower photocatalytic filter plate 43 , and the fan 45 is electrically connected to the humidity sensor 39 .

[0049] The humidity sensor 39 provided by the present invention is used to monitor the humidity of the exhaust gas when in use. When the exhaust gas passes through the silica gel filter plate 13, the silica gel particles in the silica gel filter plate 13 can adsorb water vapor in the air, thereby reducing the humidity of the air. After a period of time, the silica gel adsorption is saturated and the adsorption effect is poor. The humidity sensor 39 controls the fan 45 to be powered on, and the heat of the heating plate 14 is blown onto the silica gel filter plate 13 through the fan 45. The silica gel filter plate 13 is regenerated by heating, and the adsorption capacity is restored, and it is used for the dehumidification function again.

[0050] like Figure 2 As shown, a protective cover 23 is fixedly connected to the outer wall of the air inlet pipe 2, a condenser 24 is provided between the protective cover 23 and the air inlet pipe 2, and a refrigerator is externally connected to one side of the condenser 24.

[0051] When the condenser 24 provided by the present invention is in use, if the exhaust gas is high-temperature gas, the refrigerator is turned on when it is discharged, and the cold air is transmitted to the condenser 24 through the refrigerator. The exhaust gas is cooled by the condenser 24 to prevent the high temperature from damaging the internal components of the housing 1 and the activity of the catalyst.

[0052] like Figure 1 As shown, a base 11 is fixedly connected to the outer side wall of the bottom end of the housing 1 , and four support columns 12 are fixedly connected to the bottom of the base 11 in a circumferential arrangement, and an anti-slip pad is fixedly connected to the bottom of the support column 12 .

[0053] The support column 12 provided by the present invention is used to support the housing 1 when in use, so as to facilitate purification and deodorization of waste gas in different fields.

[0054] like Figure 7 As shown, the outer wall of the partition 44 is coated with a photocatalyst coating, and the inner wall of the drum 42 is coated with a photocatalyst coating, and the photocatalyst coating is a nano titanium dioxide coating.

[0055] When the photocatalyst coating provided by the present invention is in use, the photocatalyst coating generates active oxygen under the action of the ultraviolet lamp 46, and oxidizes and decomposes harmful gases in the air into carbon dioxide and water; the nano titanium dioxide coating has good corrosion resistance, weather resistance and high temperature resistance, and can maintain stable performance under different environmental conditions, thereby extending the service life of the photocatalyst coating; and the nano titanium dioxide has a small particle size and a large specific surface area, and can provide more reactive sites, thereby improving the efficiency of the photocatalytic reaction, and it has a good decomposition and killing effect on various organic pollutants and microorganisms; it is non-toxic and harmless to the human body and the environment, and will not release harmful substances, which meets environmental protection requirements.

[0056] Working principle: When purifying the exhaust gas, the one-way air inlet valve 22 needs to be opened, and the exhaust gas enters the housing 1 through the air inlet pipe 2. When the exhaust gas passes through the housing 1, it will pass through the dustproof plate 36, the silica gel filter plate 13, the heating plate 14, the photocatalytic filter plate 43 and the activated carbon plate 15 in sequence. The large particles of impurities in the exhaust gas will be filtered out through the dustproof plate 36, and the large particles of impurities will be filtered out in the collection pipe 3; the moisture in the exhaust gas will be filtered out through the silica gel filter plate 13, and excessive humidity may cause the catalyst surface to adsorb too much moisture, hindering the adsorption and reaction of harmful gases; the temperature of the exhaust gas will be adjusted through the heating plate 14, so that the exhaust gas is adjusted to a suitable temperature, so as to improve the catalytic effect; the exhaust gas will be photolyzed through the photocatalytic filter plate 43 to decompose some harmful gases, and then further decompose some harmful gases under the action of the ultraviolet lamp 46 and the photocatalyst coating, and finally pass through the photocatalytic filter plate 43 to continue to decompose some harmful gases, and finally pass through the activated carbon plate 15, and adsorb some harmful gases through the activated carbon plate 15, so as to achieve the purpose of deodorization, and finally be discharged from the exhaust port 16;

[0057] When the auxiliary mechanism provided by the present invention is used, the second motor 4 is turned on, and the second motor 4 drives the transmission shaft 41 to rotate through the output shaft, and the partition plate 44, the rotating drum 42 and the photocatalytic filter plate 43 are driven to rotate through the transmission shaft 41, thereby increasing the contact area between the exhaust gas and the photocatalyst coating, and the ultraviolet lamp 46 is turned on at the same time. Under the action of the ultraviolet lamp 46, the photocatalyst coating produces active oxygen, oxidizing and decomposing harmful gases in the air into carbon dioxide and water, so that the exhaust gas is fully catalyzed, and the exhaust gas is fully photocatalytically decomposed and then discharged.

[0058] By turning on the first motor 32, the first motor 32 drives the rotating shaft 33 to rotate through the output shaft, and drives the impeller 35 to rotate through the rotating shaft 33, and the exhaust gas is quickly absorbed by the impeller 35, thereby improving the efficiency of exhaust gas treatment; when the dust plate 36 filters large particles of impurities, impurities will accumulate on the surface after a period of time, thereby blocking the dust plate 36 and affecting the flow of exhaust gas, and when the rotating shaft 33 rotates, it will also drive the scraper rod 34 to rotate, and the impurities on the surface are cleaned and dropped into the collection pipe 3 by the scraper rod 34, preventing the impurities from accumulating at the bottom of the dust plate 36, thereby achieving the function of cleaning the dust on the dust plate 36;

[0059] The temperature and humidity of the exhaust gas are monitored by the temperature sensor 38 and the humidity sensor 39 respectively. When the temperature is lower than the activity of the catalyst, the heating plate 14 is powered on under the control of the temperature sensor 38. The heating plate 14 is provided with a plurality of exhaust holes 141, and the exhaust holes 141 are arranged as curved holes to increase the heating time of the exhaust gas, so that the exhaust gas is heated to a suitable temperature and then flows to the photocatalytic filter plate 43 for catalytic adsorption. If the exhaust gas is a high-temperature gas, the refrigerator is turned on when it is discharged, and the cold air is transmitted to the condenser 24 through the refrigerator, and the exhaust gas is cooled through the condenser 24 to prevent the high temperature from damaging the internal components of the housing 1 and the activity of the catalyst.

[0060] When the exhaust gas passes through the silica gel filter plate 13, the silica gel particles in the silica gel filter plate 13 can absorb water vapor in the air, thereby reducing the air humidity. After a period of time, the silica gel adsorption is saturated and the adsorption effect is poor. The fan 45 is powered on by controlling the humidity sensor 39, and the heat of the heating plate 14 is blown onto the silica gel filter plate 13 by the fan 45. The silica gel filter plate 13 is regenerated by heating, and the adsorption capacity is restored and used for the dehumidification function again.
