Description

[0002] As cities become more modernized and industrial models expand, the quality of people's living environment is becoming worse and worse; chemical plants, steel mills, pharmaceutical plants, as well as coking plants and refineries emit strong odors in the exhaust gas, which seriously pollutes the environment and affects human health.

[0003] The purification equipment used in the prior art, such as the patent document with application publication number CN107983065A, first absorbs and filters the dust, then uses photocatalytic purification, and finally uses spraying to purify the air. In the document, in order to prevent the filter from being blocked, a motor-driven stirring rod is used to clean it.

[0004] However, the circular stirring rod has a small distributed area when cleaning, and it is difficult to achieve a good anti-clogging effect. At the same time, although the impurities on the surface of the filter are cleaned and dropped, the impurities inside the filter holes are easily accumulated and cannot be removed. With the increase of blockage and pressure, the impurities in the filter holes can easily pass through the filter.

[0036] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] The embodiment of the present invention provides a photocatalytic purification device, such as Figure 1-15 As shown, the photocatalytic purification device includes: a filter box 2 fixed on the device frame 1, a catalytic purification box 3 and a solution reaction tank 63, the solution reaction tank 63 is installed at the tank body installation position 62 of the device frame 1, and is used to purify waste water, the filter box 2 and the catalytic purification box 3 are used together to purify exhaust gas, an air intake pipe 4 is arranged on one side of the filter box 2, and an air intake connecting pipe 5 and an exhaust connecting pipe 6 are arranged on the top of the filter box 2 and the catalytic purification box 3, respectively, the air intake connecting pipe 5 and the exhaust connecting pipe 6 are connected to the same drainage fan 7, which is used to extract the filtered air in the filter box 2 and discharge it into the catalytic purification box 3 for catalytic purification, and an air exhaust pipe 8 is arranged on one side of the catalytic purification box 3; the filter box 2 is divided into a filter chamber 9 and an impurity collection chamber 10, the filter chamber 9 is connected with the air inlet pipe 4 and the air inlet connecting pipe 5, the impurity collection chamber 10 is located at the bottom of the filter box 2 and below the filter chamber 9, and the filter chamber 9 and the impurity collection chamber 10 are not connected to each other; a rectangular frame 11, the rectangular frame 11 is fixedly installed in the filter chamber 9, an air filter 12 is fixedly installed in the rectangular frame 11, a plurality of filter holes 13 are evenly opened on the air filter 12, and the plurality of filter holes 13 are arranged in multiple rows; an adsorption filter dredging mechanism, the adsorption filter dredging mechanism is arranged in the filter chamber 9, for dredging the filter holes 13 of the air filter 12, the air exhaust pipe 8 is connected to the solution reaction tank 63, for introducing clean air.

[0038] In this embodiment, when in use, firstly, the power of the device is turned on and the drainage fan 7 is started. The air to be purified is sucked into the air inlet pipe 4, and the air enters the filter chamber 9 of the filter box 2. Through the action of the drainage fan 7, the filtered air is pumped into the catalytic purification box 3 through the air inlet connecting pipe 5 for further catalytic purification treatment.

[0039] In the filter chamber 9, the air is filtered through the air filter 12 fixed on the rectangular frame 11. The plurality of filter holes 13 on the air filter 12 intercept the particles in the air, while the clean air continues to flow to the air inlet connecting pipe 5.

[0040] During the operation of the equipment, the adsorption filter dredging mechanism works in the filter chamber 9 to dredge the filter holes 13 of the air filter 12 to prevent blockage. This solution adopts the method of injecting high-pressure air from the top and collecting impurities from the bottom to achieve the dredging of the filter holes 13. Different from the traditional method of only cleaning the surface, the impurities are uniformly collected into the impurity collection chamber 10, and the cleaning effect is better. This step ensures the continuous and efficient filtering ability of the air filter 12 and ensures the stability of the purification effect.

[0041] The sewage is connected to the solution reaction tank 63 for catalytic purification. The solution reaction tank 63 uses the air filtered by the former to ensure the cleanliness of the purified air and improve the effect of catalytic purification. The overall solution not only has catalytic purification of the air, but also meets the purification of wastewater and other solutions, meeting the needs of multiple uses.

[0042] In the above scheme, the solution reaction tank 63 is provided with a distributed air pipe 64 and a distributed solution pipe 65, both of which are circular, and the distributed air pipe 64 is located above the distributed solution pipe 65. The distributed air pipe 64 and the distributed solution pipe 65 are installed with a plurality of nozzles on the opposite sides thereof, which are used to spray air and wastewater respectively. The solution reaction tank 63 is provided with an ultraviolet lamp 66 inserted into the distributed air pipe 64 and the distributed solution pipe 65, which is used to catalyze the wastewater. A purified exhaust pipe 67 is installed above the solution reaction tank 63, and a clean air inlet pipe 68 is connected to the distributed air pipe 64, and the clean air inlet pipe 68 extends to the solution reaction tank 63. The outside of the solution reaction tank 63 is connected to the air exhaust pipe 8, the clean air inlet pipe 68 is provided with an air compression pump 69, a liquid storage tank 70 is fixedly installed at the bottom of the equipment frame 1, and a solution inlet pipe 71 is connected to the distributed solution pipe 65. The solution inlet pipe 71 extends to the outside of the solution reaction tank 63 and is connected to the liquid storage tank 70. A solution pump 1 72 is provided on the solution inlet pipe 71 for pumping the solution in the liquid storage tank 70 into the distributed solution pipe 65. The bottom of the solution reaction tank 63 and the liquid storage tank 70 are connected to the same solution reflux pipe 73, and a solution pump 2 74 is provided on the solution reflux pipe 73 for returning the solution in the solution reaction tank to the liquid storage tank 70. A liquid replenishment pipe 75 is provided on the liquid storage tank 70.

[0043] In this embodiment, the filter box 2 and the catalytic purification box 3 fixed on the equipment frame 1 are used together to purify the exhaust gas; at the same time, the solution reaction tank 63 is used to purify the waste water. This design realizes the combined treatment of exhaust gas and waste water, and improves the use efficiency and treatment capacity of the equipment.

[0044] The distributed air pipe 64 and the distributed solution pipe 65 inside the solution reaction tank 63 adopt a circular distributed design, and the use of the ultraviolet lamp tube 66 is to achieve a non-equilibrium photocatalytic reaction and improve the ammonia nitrogen removal rate and COD removal rate.

[0045] In use, the clean air of the air exhaust pipe 8 is extracted through the clean air introduction pipe 68 by the air compression pump 69, and then sprayed downward through the multiple nozzles on the distributed air pipe 64. At the same time, the liquid replenishing pipe 75 is used to replenish waste water in the liquid storage tank 70, and the waste water is introduced into the distributed solution pipe 65 through the solution introduction pipe 71 and the solution pump 72, and then sprayed upward through the multiple nozzles on the top of the distributed solution pipe 65. The gas and liquid phases are in countercurrent contact in the vertical direction in a high-speed flow state. After the high-speed rotating upward liquid flow collides with the high-speed downward air flow, the liquid wraps and entrains a large amount of pressurized gas. Due to the continuous increase and outward expansion of the enclosed pressurized gas, as well as the segmentation and extrusion of the downward high-speed flowing gas phase and the upward high-speed spraying liquid phase, the gas phase that is constantly wrapped and separated by the liquid phase forms a large number of bubbles and droplets, and the bubbles and droplets are entrained by the high-speed sprayed liquid and thrown outward to the reactor wall, and then return to the center to contact the high-speed flowing air flow again, and a large number of gas phases are entrained to form new bubbles and droplets.

[0046] The gas and bubble layer that continuously flows downward will hinder the liquid phase from continuing to flow upward; conversely, the liquid flow and bubble layer that continuously sprays upward will also hinder the gas phase from continuing to flow downward. When the gas and liquid phases reach momentum equilibrium, a stable foam layer will be formed. The large amount of foam formed in the foam layer not only greatly increases the mass transfer area between the gas and liquid phases, but also breaks under the impact of a large amount of high-speed sprayed liquid phase fluid and the bidirectional extrusion of the (gas) liquid phase, so that the gas and liquid phases can be separated, and the foam has an extremely high renewal frequency, which greatly enhances the reaction and separation efficiency between the gas and liquid phases, so that the device has a higher mass transfer and separation efficiency. The droplets can also increase the base area of ​​the reaction liquid, the catalyst coating and the ultraviolet lamp 66, greatly improving the reaction efficiency, and are suitable for the treatment of various wastewaters, especially for the treatment of high ammonia nitrogen wastewater.

[0047] The above specific catalyst coating and related operations are specifically referred to the patent document content of CN107051337A, which overcomes the prejudice of the prior art. The waste liquid is first formed into a foam layer, and then the foam layer is combined with a photocatalytic reaction. Since the foam is wrapped with gas, the foam contacts with the light source and the catalyst coating for reaction, and the generated ammonia will destroy the balance of the bubbles, and will also cause the bubbles to burst and separate the gas-liquid phase. The foam in the reactor itself has an extremely high renewal frequency, so that the ammonia is brought into the outside world by the gas, and then promotes the reaction to move to the right continuously, and the ammonia nitrogen removal reaction is always in a non-equilibrium state, and the reaction moves to the right all the time, so the ammonia nitrogen removal rate is greatly increased. The ammonia nitrogen removal rate in the present invention can reach more than 90%, so the device provided by the present invention is particularly suitable for the treatment of high ammonia nitrogen wastewater. In addition, the device of the present invention also has a certain effect on removing COD, and the COD removal rate can reach about 50%.

[0048] Compared with the prior art, the photocatalytic reaction device provided by the invention has a simple structure and is particularly suitable for industrial treatment of high-ammonia nitrogen wastewater. The gas-liquid two phases are in countercurrent contact in a high-speed flow state in the vertical direction, and the reaction liquid is fully in contact with the light source and the catalyst coating, which not only increases the contact area, but also keeps the ammonia nitrogen removal reaction in a non-equilibrium state during the foam layer reaction, promotes the reaction to move in the direction of generating ammonia gas, and improves the reaction efficiency. The processing volume and reaction efficiency are much greater than those of ultrasonic atomization.

[0049] The overall solution not only has the catalytic purification of air, but also meets the purification of wastewater and other solutions, meeting the needs of multiple uses.

[0050] In summary, the photocatalytic purification equipment in this embodiment not only improves the removal efficiency of ammonia nitrogen and COD by combining the design of a non-equilibrium photocatalytic reaction device, but also has a simple structure, is suitable for industrial treatment, and has broad application prospects.

[0051] In a further preferred embodiment of the present invention, the adsorption filter dredging mechanism includes a high-pressure air nozzle 14 and an impurity gathering tube 15, which are slidably arranged above and below the rectangular frame 11 and the air filter 12, respectively. The high-pressure air nozzle 14 and the impurity gathering tube 15 can slide laterally along the distribution direction of the filter holes 13 of the air filter 12. A plurality of air spray hoods 16 are arranged at the bottom of the high-pressure air nozzle 14, and a plurality of impurity collection hoods 17 are arranged at the top of the impurity gathering tube 15. The number of the air spray hoods 16 and the impurity collection hoods 17 is the same as the number of rows of the filter holes 13 and the positions correspond. The corresponding air spray hoods 16 and the impurity collection hoods 17 are located on the same longitudinal line and can block the same filter hole 13 at the same time. The hood opening diameter of the air spray hood 16 is larger than the aperture of the filter hole 13, and the hood opening diameter of the impurity collection hood 17 is larger than the hood opening diameter of the air spray hood 16.

[0052] In this embodiment, when cleaning the air filter 12, the high-pressure air nozzle 14 and the impurity collection pipe 15 slide above and below the rectangular frame 11 and the air filter 12, respectively. The two pipes move laterally along the distribution direction of the filter holes 13 of the air filter 12 to ensure that each filter hole 13 can be dredged.

[0053] The multiple air spray hoods 16 at the bottom of the high-pressure air spray pipe 14 correspond to the top of each filter hole 13 one by one as the pipe moves. When the air spray hood 16 is aligned with the filter hole 13, high-pressure air is sprayed from the air spray hood 16, and the filter hole 13 is dredged by the impact force of the air flow to remove impurities blocked in the hole.

[0054] The impurity collection pipe 15 moves synchronously with the high-pressure air nozzle 14, and the multiple impurity collection covers 17 on the top thereof correspond to the bottom of each dredged filter hole 13 one by one. Since the cover opening diameter of the impurity collection cover 17 is larger than the cover opening diameter of the air spray cover 16, it can ensure that the dredged impurities and particulate matter are effectively collected in the impurity collection cover 17, and move with the impurity collection pipe 15 to the impurity collection chamber 10 for unified treatment.

[0055] By providing the high-pressure air nozzle 14 and the air spray hood 16 , the filter holes 13 are cleared by utilizing the impact force of the high-pressure airflow, which greatly improves the clearing efficiency and ensures the continuous and efficient filtering capability of the air filter 12 .

[0056] The design of the impurity collection tube 15 and the impurity collection cover 17 enables the dredged impurities and particulate matter to be accurately collected into the impurity collection chamber 10, thus avoiding secondary contamination of impurities and clogging of equipment.

[0057] The sliding arrangement of the high-pressure air nozzle 14 and the impurity collecting pipe 15, and the corresponding arrangement of the air spray hood 16 and the impurity collecting hood 17, make the entire dredging mechanism compact in structure and stable in operation, effectively improving the overall performance and reliability of the equipment.

[0058] In a further preferred embodiment of the present invention, the adsorption filter dredging mechanism also includes a connecting pipe 18, an impurity discharge hose 19, an impurity collecting filter bag 20, a high-pressure air introduction mechanism and a transverse driving power mechanism, the connecting pipe 18 is connected to the impurity gathering pipe 15, the impurity discharge hose 19 is connected to the connecting pipe 18, and the impurity discharge end extends into the impurity collecting chamber 10, the impurity collecting filter bag 20 is provided in the impurity collecting chamber 10, the bag mouth of the impurity collecting filter bag 20 is sleeved on the impurity discharge end of the impurity discharge hose 19, and a filter bag retrieval door 21 is detachably installed on one side of the bottom of the filter box 2, and the filter bag retrieval door 21 has an exhaust hole 22.

[0059] In this embodiment, after the impurities are collected by the impurity collecting pipe 15, the impurities are transferred to the impurity collecting filter bag 20 in the impurity collecting chamber 10 through the connecting pipe 18 and the impurity discharging hose 19. The bag opening of the impurity collecting filter bag 20 is tightly sleeved on the impurity discharging end of the impurity discharging hose 19 to ensure that the impurities will not leak while allowing air circulation.

[0060] The impurities are stored in the impurity collecting filter bag 20. At the same time, the impurity collecting filter bag 20 also plays a role of secondary filtration. As the impurities accumulate, the impurity collecting filter bag 20 will gradually become saturated.

[0061] When the impurity collection filter bag 20 reaches a certain degree of saturation, the operator can easily remove and replace the impurity collection filter bag 20 by opening the filter bag access door 21. The design of the filter bag access door 21 is convenient for operation, and the exhaust hole 22 thereon allows the air in the impurity collection chamber 10 to be discharged to avoid pressure accumulation.

[0062] In a further preferred embodiment of the present invention, the high-pressure air introduction mechanism includes a connecting pipe 23, an air intake hose 24, an external connecting pipe 25, a regulating valve 26 and a regulating valve 27, the connecting pipe 23 is connected to the high-pressure air nozzle 14, the air intake hose 24 is connected to the connecting pipe 23, the external connecting pipe 25 passes through the box wall of the filter box 2, the air intake end is connected to the exhaust connecting pipe 6, and the exhaust end is connected to the air intake end of the air intake hose 24, the regulating valve 1 26 is arranged on the exhaust connecting pipe 6, the air intake end of the external connecting pipe 25 is located between the induced draft fan 7 and the regulating valve 1 26, and the regulating valve 2 27 is arranged on the external connecting pipe 25.

[0063] In this embodiment, high-pressure air enters the connecting pipe 23 through the air intake hose 24, and is then introduced into the high-pressure air nozzle 14. In this process, the external connecting pipe 25 plays a key role as a bridge connecting the exhaust connecting pipe 6 and the air intake hose 24. The filtered clean air is used without worrying about the problem of secondary pollution. The air intake end of the external connecting pipe 25 is located between the drainage fan 7 and the regulating valve 1 26, ensuring that the high-pressure air can smoothly enter the external connecting pipe 25 under the action of the drainage fan 7. When cleaning is not required, the regulating valve 2 27 can be closed and the regulating valve 1 26 can be fully opened. When cleaning, the regulating valve 1 26 can be adjusted down and the regulating valve 2 27 can be opened.

[0064] The regulating valve 1 26 and regulating valve 2 27 are respectively arranged on the exhaust connecting pipe 6 and the external connecting pipe 25, and are used to adjust the flow and pressure of the high-pressure air. By adjusting the opening of the two regulating valves, the amount of high-pressure air entering the high-pressure air nozzle 14 can be accurately controlled, thereby achieving fine adjustment of the filter screen dredging effect.

[0065] The regulated high-pressure air is sprayed from the air spray cover 16 at the bottom of the high-pressure air spray pipe 14 to clear the filter holes 13 of the air filter 12. This process not only removes the impurities blocked in the filter holes 13, but also further improves the filtering efficiency of the air filter 12 through the flushing effect of the high-pressure airflow.

[0066] The high-pressure air is uniformly sprayed onto the filter holes 13 through the air spray hood 16, which not only removes the blockage, but also improves the filtering efficiency of the filter screen through the flushing effect, thereby extending the service life of the filter screen.

[0067] In a further preferred embodiment of the present invention, the transverse driving power mechanism includes a fixed plate 1 28, a fixed plate 29, two guide strips 30, two transverse screws 31, two synchronous wheels 1 32, a synchronous belt 1 33, a motor seat 34 and a driving motor 35. The fixed plate 1 28 and the fixed plate 29 are respectively fixedly mounted on the connecting pipe 23 and the connecting pipe 1 18. The two guide strips 30 slide through the fixed plate 1 28 and the fixed plate 29 respectively. The two ends of the two guide strips 30 are respectively fixedly connected to the inner walls of the two sides of the filter chamber 9. The two transverse screws 31 respectively penetrate the fixed plate 1 28 and the fixed plate 29 by threaded driving. 8 and a fixed plate 29, the two ends of the two transverse screws 31 are rotatably connected to the inner walls of the two sides of the filter chamber 9, and the two ends of the two transverse screws 31 extend outside the filter box 2. The guide strips 30 and the transverse screws 31 are arranged in the same direction. The two synchronous wheels 32 are respectively fixedly mounted on the same end of the two transverse screws 31, and the synchronous belt 33 is sleeved on the two synchronous wheels 32. The motor seat 34 is fixedly mounted on one side of the filter box 2, and the drive motor 35 is fixedly mounted on the motor seat 34. The output shaft of the drive motor 35 is fixedly connected to the end of the corresponding transverse screw 31.

[0068] In this embodiment, fixed plate 1 28 and fixed plate 29 are respectively fixedly mounted on connecting pipe 2 23 and connecting pipe 1 18, serving as supporting structures for the transverse driving power mechanism. Two transverse screws 31 also penetrate fixed plate 1 28 and fixed plate 29 by means of threaded drive, and are rotationally connected to the inner walls on both sides of the filter chamber 9, providing power for transverse movement.

[0069] The driving motor 35 is fixedly mounted on one side of the filter box 2 through the motor base 34, and its output shaft is fixedly connected to the end of one of the transverse screws 31. When the driving motor 35 is started, it drives the transverse screw 31 to rotate. Since the synchronous wheel 1 32 is fixedly mounted on the same end of the two transverse screws 31 and connected by the synchronous belt 1 33, when one transverse screw 31 rotates, it drives the other transverse screw 31 to rotate synchronously. In this way, the two transverse screws 31 can drive the connecting pipe 2 23 and the connecting pipe 1 18 (and the high-pressure air nozzle 14 and the impurity gathering pipe 15 thereon) to move transversely under the guidance of the guide strip 30 at the same speed and direction.

[0070] In a further preferred embodiment of the present invention, the high-pressure air nozzle 14, the impurity gathering tube 15, the connecting tube 1 18 and the connecting tube 2 23 are all hard tubes, and the frame edge width of the rectangular frame 11 is greater than the width of the high-pressure air nozzle 14, the impurity gathering tube 15, the connecting tube 1 18, the connecting tube 2 23, the fixing plate 1 28 and the fixing plate 2 29.

[0071] In this embodiment, hard pipes are used for the high-pressure air nozzle 14, the impurity collection pipe 15, the connecting pipe 1 18 and the connecting pipe 2 23. The hard pipe has the characteristics of stable structure, not easy to deform, and strong pressure bearing capacity, which ensures the smooth transmission of air and impurities, and also provides a stable support for the entire dredging mechanism.

[0072] The frame width of the rectangular frame 11 is designed to be greater than the width of all the above-mentioned hard pipes. Such a design ensures that the high-pressure air nozzle 14, the impurity collection pipe 15, the connecting pipe 1 18, the connecting pipe 2 23, the fixing plate 1 28 and the fixing plate 2 29 are hidden in the corner when not in operation.

[0073] In a further preferred embodiment of the present invention, the diameter of the external connecting pipe 25 is larger than the diameter of the air intake hose 24, and the air intake end of the external connecting pipe 25 is tilted along the windward direction, which is the direction in which air is exhausted from the outlet end of the induced draft fan 7 to the exhaust connecting pipe 6.

[0074] In this embodiment, the diameter of the external connecting pipe 25 is designed to be larger than the diameter of the air intake hose 24. This design has two main purposes: first, to reduce the resistance of the air flow in the pipeline, so that the high-pressure air can more smoothly enter the air intake hose 24 from the exhaust connecting pipe 6 through the external connecting pipe 25, and then enter the high-pressure air nozzle 14; second, to form an air flow buffer in the external connecting pipe 25, which helps to stabilize the air flow pressure and flow, and prevent the air flow from directly impacting the air intake hose 24 to cause damage or affect the dredging effect.

[0075] The air inlet end of the external connecting pipe 25 is tilted in the windward direction, where the windward direction is defined as the direction in which the air outlet end of the induced draft fan 7 exhausts air toward the exhaust connecting pipe 6. This design is to better capture and utilize the airflow generated by the induced draft fan 7, so that high-pressure air can enter the external connecting pipe 25 more efficiently. The tilted air inlet end can also guide the airflow to flow along the inner wall of the pipe, reduce eddy currents and turbulence, and further improve the stability and efficiency of the airflow.

[0076] The high-pressure air introduction mechanism and the lateral drive power mechanism work together to achieve accurate dredging and impurity collection of the air filter 12. In this process, the design optimization of the external connection pipe 25 further improves the introduction efficiency and stability of the high-pressure air, ensuring the consistency and reliability of the dredging effect.

[0077] In a further preferred embodiment of the present invention, the fixing plate 1 28 and the fixing plate 2 29 are both provided with rectangular sliding openings and threaded holes, the guide strip 30 slides through the corresponding rectangular sliding openings, and the transverse screw 31 penetrates the corresponding threaded holes by threaded engagement.

[0078] In this embodiment, the design of the rectangular sliding opening and the threaded hole, the sliding installation of the guide strip 30 in the rectangular sliding opening, and the threaded screw connection of the transverse screw 31 together ensure the precise guidance and stable movement of the transverse mechanism. This ensures the precise dredging and impurity collection of the high-pressure air nozzle 14 and the impurity collection pipe 15 on the air filter 12.

[0079] In a further preferred embodiment of the present invention, an activated carbon layer 36 is detachably installed in the filter chamber 9, and the activated carbon layer 36 is located above the air filter 12 and the adsorption filter dredging mechanism.

[0080] In this embodiment, a detachable activated carbon layer 36 is designed in the filter cavity 9. This design enables the activated carbon layer 36 to be easily installed and removed, and is convenient for users to replace or clean it according to actual needs, thereby maintaining its good filtering performance.

[0081] The activated carbon layer 36 is placed above the air filter 12 and the adsorption filter dredging mechanism, ensuring that the air is filtered by the activated carbon layer 36 after passing through the air filter 12, effectively removing impurities such as odors and harmful gases in the air.

[0082] In a further preferred embodiment of the present invention, the catalytic purification box 3 is divided into an upper photocatalytic purification chamber 37 and a lower spray chamber 38, the photocatalytic purification chamber 37 is connected to the exhaust connecting pipe 6, and the spray chamber 38 is connected to the air exhaust pipe 8. Multiple rows of photocatalytic lamps 39 and catalytic reaction layers 40 are staggeredly installed in the photocatalytic purification chamber 37 for catalytic purification of the air, and the photocatalytic purification chamber 37 and the spray chamber 38 are connected by a conductive bend pipe 41.

[0083] In this embodiment, the interior of the catalytic purification box 3 is cleverly divided into an upper photocatalytic purification chamber 37 and a lower spray chamber 38. The photocatalytic purification chamber 37 is connected to the exhaust connecting pipe 6 to receive the air to be purified from the exhaust connecting pipe 6; the spray chamber 38 is connected to the air exhaust pipe 8 to discharge the purified air. At the same time, the photocatalytic purification chamber 37 and the spray chamber 38 are connected through a conductive elbow 41 to ensure that the air can flow smoothly between the two chambers.

[0084] In the photocatalytic purification chamber 37, we staggeredly install multiple rows of photocatalytic lamps 39 and catalytic reaction layers 40. The photocatalytic lamps 39 emit light of a specific wavelength to activate the catalyst on the catalytic reaction layer 40, causing it to produce a strong redox reaction, thereby catalytically purifying harmful substances in the air.

[0085] A spray is provided in the spray chamber 38. When air enters the spray chamber 38 from the photocatalytic purification chamber 37 through the conducting elbow 41, the spray device sprays purification liquid into the air to further remove residual impurities and odors in the air, and finally discharges the purified air through the air exhaust pipe 8.

[0086] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0087] In another embodiment of the present invention, a water filter net 42 is fixedly installed in the spray chamber 38, and the installation height of the water filter net 42 is lower than the air exhaust pipe 8 and the conducting elbow 41. A water pump 43 is installed below the water filter net 42, and a spray pipe 44 is installed at the discharge end of the water pump 43. The spray pipe 44 extends to above the exhaust end of the conducting elbow 41 and is installed with a water balancing pipe 45. A plurality of atomizing nozzles 46 are installed on the water balancing pipe 45. A sewage pipe 47 is installed at the bottom of the catalytic purification box 3, and the sewage pipe 47 is connected to the spray chamber 38. A water supply pipe 48 is installed on the side of the catalytic purification box 3, and the water supply pipe 48 is connected to the spray chamber 38.

[0088] In this embodiment, a water filter net 42 is fixedly installed in the spray chamber 38, and its installation height is lower than the air exhaust pipe 8 and the conducting elbow pipe 41 to ensure that the purified air will not be discharged with water droplets. A water pump 43 is installed below the water filter net 42 to extract the accumulated water in the spray chamber 38 and recycle it through the spray pipe 44 connected to the drainage end.

[0089] The spray pipe 44 extends to the upper part of the exhaust end of the conducting elbow 41, and is installed with a water balancing pipe 45, on which a plurality of atomizing nozzles 46 are arranged. This design enables the water drawn by the water pump 43 to pass through the spray pipe 44 and the water balancing pipe 45, and finally be evenly sprayed in the form of atomization on the air entering the spray chamber 38 through the conducting elbow 41, so as to further remove the residual impurities in the air.

[0090] In order to keep the water in the spray chamber 38 clean, a sewage pipe 47 is installed at the bottom of the catalytic purification box 3, which is connected to the spray chamber 38 and is used to discharge the accumulated dirt. At the same time, a water supply pipe 48 is installed on the side of the catalytic purification box 3, which is also connected to the spray chamber 38 and is used to replenish fresh water to ensure the continuous and stable operation of the spray system.

[0091] Through the interception of the water filter 42, the recycling of the water pump 43, and the uniform spraying of the atomizing nozzle 46, the residual impurities and odors in the air are further removed, thereby improving the purification effect.

[0092] In another embodiment of the present invention, an air guide plate 49 is fixedly installed in the spray chamber 38, and the air guide plate 49 is arranged corresponding to the air exhaust pipe 8. An operating door 50 is detachably installed on one side of the filter box 2 and the catalytic purification box 3, and the two operating doors 50 correspond to the filter chamber 9 and the photocatalytic purification chamber 37 respectively.

[0093] In this embodiment, an air guide plate 49 is fixedly installed in the spray chamber 38, and the air guide plate 49 is arranged corresponding to the air exhaust pipe 8. The function of the air guide plate 49 is to guide the air purified by the spray to flow to the air exhaust pipe 8, to prevent the incoming air from rushing straight, and to be arranged obliquely to block part of the water vapor.

[0094] In order to facilitate the user to maintain and clean the inside of the filter box 2 and the catalytic purification box 3, an operation door 50 is detachably installed on one side of the filter box 2 and the catalytic purification box 3. The two operation doors 50 correspond to the filter chamber 9 and the photocatalytic purification chamber 37, respectively, so that the user can easily open the operation door 50 and enter the filter chamber 9 and the photocatalytic purification chamber 37 to perform necessary maintenance work.

[0095] In another embodiment of the present invention, two cleaning plates 51 are fixedly installed on the top of the impurity gathering tube 15, and the two cleaning plates 51 are respectively located on both sides of the plurality of impurity collecting covers 17, and the two cleaning plates 51 are used to clean the lower surface of the air filter 12 following the lateral movement of the impurity gathering tube 15.

[0096] In this embodiment, two cleaning plates 51 are fixedly installed on the top of the impurity collection pipe 15. The two cleaning plates 51 are respectively located on both sides of the plurality of impurity collection covers 17, ensuring that the cleaning plates 51 can fully contact and clean the lower surface of the air filter 12 when the impurity collection pipe 15 moves laterally.

[0097] When the impurity collection pipe 15 is driven by the driving mechanism to move laterally, the cleaning plate 51 moves accordingly. The bottom edge of the cleaning plate 51 maintains a certain contact pressure with the lower surface of the air filter 12, thereby effectively cleaning the dust and impurities attached to the lower surface of the air filter 12.

[0098] By introducing the cleaning plate 51, an automatic cleaning function is realized on the lower surface of the air filter 12. This not only reduces the frequency and difficulty of manual cleaning, but also improves the cleaning efficiency, ensuring the continuous and efficient filtering performance of the air filter 12.

[0099] Regularly cleaning the lower surface of the air filter 12 can effectively prevent dust and impurities from accumulating on the filter, thereby avoiding clogging and damage to the filter. This helps to extend the service life of the air filter 12 and reduce replacement costs.

[0100] In another embodiment of the present invention, a plurality of electrostatic adsorption rods 52 are provided below the activated carbon layer 36, and the plurality of electrostatic adsorption rods 52 can be detachably installed in the filter chamber 9. A cleaning mechanism is provided in the filter chamber 9, and the cleaning mechanism includes a scraping sleeve 53 slidably mounted on the plurality of electrostatic adsorption rods 52, a synchronous plate 54 is fixedly installed on the bottom of the scraping sleeve 53, and the bottom of the synchronous plate 54 is fixedly connected to a fixed plate 28, and a cleaning brush 55 is installed on the top of the scraping sleeve 53, and the cleaning brush 55 is in contact with the bottom of the activated carbon layer 36.

[0101] In this embodiment, in order to further enhance the air purification effect and improve the maintenance convenience of the equipment, a plurality of electrostatic adsorption rods 52 are arranged below the activated carbon layer 36, and these electrostatic adsorption rods 52 can be detachably installed in the filter chamber 9. In addition, the cleaning mechanism includes a scraping plate 53 slidably sleeved on the plurality of electrostatic adsorption rods 52, and the bottom of the scraping plate 53 is fixedly connected to the fixed plate 28 through a synchronization plate 54. A cleaning brush 55 is installed on the top of the scraping plate 53 to keep it in contact with the bottom of the activated carbon layer 36.

[0102] By introducing the electrostatic adsorption rod 52, the electrostatic adsorption principle is utilized to efficiently adsorb tiny particles and harmful substances in the air, further improving the air purification effect. At the same time, the detachable design of the electrostatic adsorption rod 52 allows the user to easily clean or replace it to maintain its continuous adsorption capacity.

[0103] The design of the cleaning mechanism is to drive the scraping plate 53 to slide on the multiple electrostatic adsorption rods 52 by moving the synchronous plate 54, so that the bottom of the activated carbon layer 36 is cleaned by the cleaning brush 55. This design not only simplifies the maintenance process, but also improves the maintenance efficiency and ensures the continuous and stable operation of the equipment.

[0104] In another embodiment of the present invention, the filter box 2 is provided with a filter bag beating mechanism, and the filter bag beating mechanism includes a camshaft 56 rotatably installed on the other side of the impurity collecting chamber 10 opposite to the filter bag loading and unloading door 21, and a beating cam 57 is fixedly installed on a section of the camshaft 56 located in the impurity collecting chamber 10, which is used to beat the impurity collecting filter bag 20 expanded by air, and a power transmission shaft 58 is rotatably installed on the motor seat 34. The power transmission shaft 58 and the corresponding transverse screw 31 are both fixedly sleeved with a bevel gear 59, and the two bevel gears 59 are meshed with each other. A synchronous wheel 2 60 is fixedly installed on one end of the camshaft 56 located outside the filter box 2 and on the power transmission shaft 58, and the same synchronous belt 2 61 is sleeved on the multiple synchronous wheels 2 60.

[0105] In this embodiment, in order to improve the cleaning efficiency of the impurity collection filter bag 20 and ensure continuous and efficient air purification capabilities, a filter bag beating mechanism is designed and integrated into the filter box 2. The core component of the mechanism includes a camshaft 56 rotatably mounted in the impurity collection chamber 10, and a beating cam 57 is fixedly mounted on the camshaft 56. In addition, a power transmission shaft 58 is rotatably mounted on the motor seat 34, and the power transmission shaft 58 and the transverse screw 31 realize power transmission through a bevel gear 59, while the camshaft 56 and the power transmission shaft 58 realize synchronous rotation through a synchronous wheel 2 60 and a synchronous belt 2 61. When the drive motor 35 drives the transverse screw 31 to rotate, it will drive the power transmission shaft 58 and the camshaft 56 to rotate synchronously, and then drive the beating cam 57 to beat the impurity collection filter bag 20 that is expanded by the blast.

[0106] The design of the filter bag beating mechanism allows the impurity collecting filter bag 20 to be beaten by the beating cam 57 while being expanded by air, thereby effectively removing dust and impurities attached to the filter bag, improving the cleaning efficiency, thereby extending the service life of the filter bag and reducing the replacement frequency.

[0107] By utilizing the power transmission path of the transverse screw 31 and combining transmission components such as the bevel gear 59, the synchronous wheel 60 and the synchronous belt 61, the filter bag beating mechanism and the transverse mechanism are linked, so that the entire equipment has more comprehensive functions while maintaining a compact structure.

[0108] To sum up, compared with the relevant technology, the present device adopts an adsorption filter dredging mechanism to dredge the filter holes 13 of the air filter 12 to prevent blockage, and adopts the method of injecting high-pressure air from the top and collecting impurities from the bottom to achieve the dredging of the filter holes 13. Different from the traditional method of only cleaning the surface, the impurities are uniformly collected into the impurity collection chamber 10, and the cleaning effect is better. This step ensures the continuous and efficient filtering ability of the air filter 12 and ensures the stability of the purification effect. At the same time, the overall solution not only has catalytic purification of the air, but also meets the purification of wastewater and other solutions, and meets the needs of multiple uses.
