DETAILED DESCRIPTION

[0019] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0020] Example one: As Figure 1 , Figure 2 , Figure 3And Figure 4 As shown in FIG. 1, a suspension type large range air purification system comprises a plurality of adsorption covers 10, in the present application, the plurality of adsorption covers 10 are respectively suspended under the ceiling of a factory building in which harmful gas absorption and purification is required, the upper end surface of each adsorption cover 10 is communicated with a connecting cylinder 11, the upper portion of each connecting cylinder 11 is communicated with a gas storage tank 12, each two adjacent gas storage tanks 12 are communicated with a V-shaped pipeline 13, and the middle port of each V-shaped pipeline 13 is communicated with an exhaust fan 14. When the harmful gas in the chemical plant is purified, the air in the V-shaped pipeline 13 connected with the exhaust fan 14 is discharged, the air in the V-shaped pipeline 13 is reduced, the pressure is reduced, and then the harmful gas outside is adsorbed into the purification system through the gas storage tank 12, the connecting cylinder 11 and the adsorption cover 10, and the purified and cooled air is discharged by the exhaust fan 14 and blown to the equipment in the factory that needs to be cooled.

[0021] Further, the output end of each exhaust fan 14 is communicated with an extension connecting pipe 16, the lower end of each extension connecting pipe 16 is connected with a diffusion cover 15, and the diffusion cover 15 is arranged to diffuse the air blown out by the exhaust fan 14, so that the cooling area of the purification system is increased, and the worker can move and adjust the diffusion cover 15 at multiple angles and in multiple directions through the bending and extension structure of the extension connecting pipe 16, so that the air discharged by the purification system can more comprehensively cool the equipment in the factory.

[0022] Further, as shown in FIG. 1, Figure 3 , Figure 6 , Figure 7 And Figure 9 The inside of each adsorption cover 10 is provided with a trapezoidal frame 17, the upper end surface of each two adjacent trapezoidal frames 17 and the inner side wall of the adsorption cover 10 are rotatably connected with a plurality of elastic connecting rods 34, the lower end of each connecting cylinder 11 is arranged along the inner top wall of the adsorption cover 10 and is provided with a filter cover 18, and the lower end of each filter cover 18 is connected with a folding sealing ring 19 between the trapezoidal frame 17. After the external air is sucked into the inside of the adsorption cover 10 by the exhaust fan 14, it enters the inside of the connecting cylinder 11, the gas storage tank 12 and other components through the filtration of the filter cover 18, the filter cover 18 can filter large particles of dust and impurities in the gas, so as to avoid that the large particles of impurities enter the inside of the subsequent filtration and purification components and cause the blockage of some parts.

[0023] Further, as shown in FIG. 1, Figure 4 And Figure 9 And Figure 10As shown, the outer upper and lower ends of each filter cover 18 are rotatably provided with a clamping ring 20, and a plurality of connecting plates 21 are connected between every two adjacent clamping rings 20. A cleaning sponge 22 is fixedly arranged on the inner side wall of each connecting plate 21 and the filter cover 18. One side of each cleaning sponge 22 is in sliding abutment with the outer circular surface of the filter cover 18. In order to prevent the filter cover 18 from being blocked during long-term filtering of large particles in the gas, the plurality of connecting plates 21 and cleaning sponges 22 arranged on the outer circular surface of each filter cover 18 are rotated regularly. During rotation, the cleaning sponges 22 continuously wipe and clean the outer circular surface of the filter cover 18, so that the large particles adhering to the outer circular surface of the filter cover 18 fall off, effectively reducing the probability of blockage of the filter holes on the outer circular surface of the filter cover 18. A gear ring 23 is arranged on the outer circular surface of each clamping ring 20 at the upper end. One side of each gear ring 23 is rotatably meshed with a transmission gear. A servo motor is arranged above each transmission gear at the upper end of the adsorption cover 10. The output end of the servo motor is fixedly connected to the upper end surface of the transmission gear through the adsorption cover 10. The output end of the servo motor drives the transmission gear to rotate, which in turn drives the gear ring 23 to rotate, and further drives the clamping ring 20, the connecting plate 21 and the cleaning sponge 22 to rotate, thereby cleaning the outer circular surface of the filter cover 18.

[0024] It should be noted that the outer part of each gear ring 23 and the transmission gear meshed therewith is provided with a protective cover, which can provide protection against dirt and dust for the gear and the gear ring 23, thereby improving the service life of the system.

[0025] Further, as shown in Figure 3 and Figure 6 , a sealing plate 48 is detachably arranged at the lower end of each trapezoidal frame 17. A V-shaped ring groove 29 is arranged on the upper end surface of each folding sealing ring 19. A plurality of first through holes 30 are arranged in the inner part of each V-shaped ring groove 29. An annular plate 49 is arranged on the outer part of the plurality of first through holes 30 at the upper end surface of the sealing plate 48. Large particulate impurities adhering to the outer circular surface of the filter cover 18 will fall downward and be stored in the inner part of the V-shaped ring groove 29 under the rotating cleaning of the plurality of cleaning sponges 22, and then fall into the inner part of the annular plate 49 through the plurality of first through holes 30. The inner storage of impurities in the annular plate 49 can be cleaned by detaching the sealing plate 48, thereby ensuring the cleanliness between the adsorption cover 10 and the trapezoidal frame 17.

[0026] Further, as shown in Figure 3 , Figure 4 and Figure 5As shown, V-shaped ring film 35 is arranged between every two adjacent adsorption cover 10 and trapezoidal frame 17, end surface of each V-shaped ring film 35 is provided with a plurality of second through holes 36, the arrangement of V-shaped ring film 35 and second through hole 36 forms effective shielding of the gap between adsorption cover 10 and trapezoidal frame 17 without affecting the entry of external toxic gas, preventing external flying insects and other micro-animals from entering the inside of the purification system through the gap between adsorption cover 10 and trapezoidal frame 17, affecting the normal use of the purification system.

[0027] Further, as shown in Figure 3 、 Figure 4 、 Figure 6 and Figure 8 and Figure 10 , the inside of each connecting cylinder 11 is provided with a plurality of cross supports 24, a plurality of adjacent cross supports 24 are rotatably arranged inside the rotating shaft 25, the outside of each rotating shaft 25 is provided with a plurality of stirring rods 26, the inner top surface of each trapezoidal frame 17 is fixedly provided with a motor 27, the output end of each motor 27 passes through the trapezoidal frame 17 and is fixedly connected with the bottom of the adjacent rotating shaft 25, and a plurality of water mist nozzles 31 are arranged on the lower end surface of each rotating shaft 25 located at the top.

[0028] When purifying the gas containing harmful substances such as sulfur generated by the boiler of the chemical plant, after the gas is preliminarily filtered by the filter cover 18, it enters the inside of the connecting cylinder 11, at this time, the water mist sprayed by a plurality of water mist nozzles 31 can react with the harmful substances in the gas to remove the harmful substances in the gas, and the generated liquid falls between the trapezoidal frame 17 and the folded sealing ring 19 to form a cavity, the upper end surface of each trapezoidal frame 17 is provided with a flow guide cover 51 above each motor 27, each flow guide cover 51 is rotatably connected with the adjacent rotating shaft 25, and a plurality of third through holes 47 are arranged between every two adjacent folded sealing ring 19 and flow guide cover 51 on the upper end surface of the trapezoidal frame 17, the neutralized liquid falling into the cavity between the trapezoidal frame 17 and the folded sealing ring 19 is stored in the inside of the annular plate 49 below through the plurality of third through holes 47, which is convenient for subsequent cleaning, and in the process of neutralization of harmful substances in the gas, the rotating shaft 25 and the plurality of stirring rods 26 are driven to rotate by the output end of the motor 27, which can form stirring between the water mist and the gas in the connecting cylinder 11, so that the gas and the neutralizing liquid are fully mixed and reacted, and the neutralization effect of the harmful substances in the gas is better.

[0029] The top of each gas storage tank 12 is provided with a water storage tank 32, which stores neutralization reaction liquid and is equipped with an outward output water pump. Each water storage tank 32 is in communication with the adjacent water mist sprayers 31 through a connecting hose 33. The connecting hose 33 and the water storage tank 32 can provide sufficient liquid for the water mist sprayers 31 to meet the needs of neutralization reaction.

[0030] A damping ring 50 is arranged at the rotating connection between each two adjacent rotating shafts 25 and the cross support frame 24. The damping ring 50 can absorb the vibration generated when the rotating shaft 25 rotates.

[0031] Further, as shown in Figure 1 , Figure 3 and Figure 4 , one side of each gas storage tank 12 is provided with a drying filter plate 37 at the port of the V-shaped pipeline 13. One side of each drying filter plate 37 is provided with an opening for dismounting and mounting the drying filter plate 37. The opening facilitates the installation, dismounting and replacement of the drying filter plate 37. After the neutralization reaction, the gas enters the V-shaped pipeline 13 through the connecting cylinder 11. The gas contains a high amount of moisture. The drying filter plate 37 can remove the excess moisture in the gas through absorption and filtration, thereby facilitating further processing of the gas. The two sides of each drying filter plate 37 are provided with sealing rings on the inner side walls of the V-shaped pipeline 13, which can effectively increase the sealing between the drying filter plate 37 and the V-shaped pipeline 13, preventing the gas that has not been dried by the drying filter plate 37 from entering the inside of the V-shaped pipeline 13 through the gap between the drying filter plate 37 and the V-shaped pipeline 13.

[0032] It should be noted that the drying filter plate 37 only performs drying treatment on the passing gas and does not play a filtering role. Therefore, the internal holes of the drying filter plate 37 will not be blocked during the drying process of the gas passing through the drying filter plate 37.

[0033] Further, as shown in Figure 3 and Figure 4 , a plurality of dust absorption filter plates 38 are arranged in the inclined pipeline of each V-shaped pipeline 13. During the process of the gas passing through the V-shaped pipeline 13 and entering the exhaust fan 14, the staggered arrangement of the plurality of dust absorption filter plates 38 can make the gas contact and react with the side walls of each dust absorption filter plate 38, further removing harmful impurities inside the gas. Moreover, the staggered arrangement of the plurality of dust absorption filter plates 38 can buffer and guide the gas flowing through the V-shaped pipeline 13, increase the contact time of the gas with the plurality of dust absorption filter plates 38, and improve the removal effect of harmful impurities inside the gas.

[0034] Further, as shown in Figure 3 and Figure 4As shown, the two sides of each exhaust fan 14 are provided with liquid cooling pipes 41 inside the V-shaped pipe 13, and the upper end of each liquid cooling pipe 41 is provided with a liquid cooler 42 on the upper end surface of the V-shaped pipe 13. The output end and the input end of each liquid cooler 42 are in communication with the adjacent liquid cooling pipes 41, forming a circulation of the cooling liquid inside the liquid cooling pipes 41, so that the temperature of the gas entering the inside of the exhaust fan 14 through the V-shaped pipe 13 is reduced, and the gas blown out by the diffusion cover 15 and the telescopic connecting pipe 16 can effectively cool the equipment in the factory that needs to be cooled.

[0035] System air purification process: First, during the operation of the factory, multiple exhaust fans 14 are started simultaneously, and the multiple exhaust fans 14 extract the air inside the V-shaped pipe 13 in communication with each other. At this time, the pressure inside the V-shaped pipe 13 is reduced, and the external gas is sucked into the gap between the adsorption cover 10 and the trapezoidal frame 17, and the air inside the adsorption cover 10 is first filtered by the V-shaped ring membrane 35 and the second through hole 36, and then filtered by the filter cover 18, removing large particles in the gas. The filtered gas enters the inside of the connecting cylinder 11 from the filter cover 18, at which time the multiple water mist nozzles 31 spray neutralizing reaction liquid spray, and the misty neutralizing reaction liquid is stirred by the multiple rotating shafts 25 and the stirring rods 26 to neutralize the acidic and alkaline harmful substances inside the gas. The waste water produced by the reaction leaks into the inside of the sealing plate 48 through the multiple third through holes 47 for storage.

[0036] Then, the gas after the neutralization reaction treatment is dehumidified and filtered by the dry filter plate 37, moves to the inside of the pipe of the V-shaped pipe 13, and is cooled by the liquid cooling pipe 41 and the liquid cooler 42 after being filtered by the multiple dust collection filter plates 38. The gas is blown to the outside of the equipment that needs to be cooled by the exhaust fan 14, the diffusion cover 15 and the telescopic connecting pipe 16, forming a filtering and cooling cycle of harmful gas inside the factory.

[0038] Further, as shown in Figure 3 and Figure 4 each two adjacent connecting rods 44 and vibrators 45 are connected with a shock pad 46, the shock pad 46 can reduce the vibration influence of the vibrator 45 on the connecting rod 44 when the vibrator 45 vibrates the gas storage tank 12, one side of each dust collection filter plate 38 is provided with a long hole 39 on the inclined bottom surface of the V-shaped pipeline 13, and a storage long groove 40 is detachably arranged below each long hole 39 on the inclined lower end surface of the V-shaped pipeline 13, the dust collected on one side of the dust collection filter plate 38 falls through the long hole 39 and is stored in the storage long groove 40, and the detachable arrangement of the storage long groove 40 facilitates the cleaning of the dust stored in the storage long groove 40.
