Description

Technical Field

[0001] The invention relates to the technical field of spray cooling, in particular to a spray cooling device for a spinning room air conditioning unit. Background Art

[0002] In the polyester filament production system, the spinning process is the core process link. The precise control of its various process parameters directly affects the physical performance indicators of the final product. The environment of the spinning room is also a factor that affects the cooling and forming of polyester filaments. In the spinning workshop, due to equipment operation and raw material processing, the return air often carries a high content of oil and dust. At the same time, the workshop temperature is also high. In order to improve this situation, a spray section water spray system is usually used to conduct a comprehensive washing, dust reduction and humidification control on the air source entering the air conditioning system.

[0003] There are defects in the existing technology: there is a shortcoming in using this spray humidification technology. Industrial water is generally not completely purified, and its water quality usually contains more suspended impurities and other particulate matter. After long-term operation, these impurities will enter the spray system with the water flow, and gradually accumulate in the spray pipes and nozzles, forming blockages. This will not only lead to uneven distribution of water mist and reduced spraying effect, but may also make the humidification and dust reduction functions ineffective in some areas. Summary of the invention

[0004] The object of the present invention is to provide a spray cooling device for a spinning room air conditioning unit to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: the spray cooling device includes a spray device, one end of which is equipped with an air inlet pipe and a sewage tank, the other end of which is equipped with an air outlet pipe, and the top of the spray device is equipped with a coarse filter device, a fine filter device and a bottom plate in sequence along the direction of the water flow, and a clean water tank is installed on the bottom plate. The water flows into the coarse filter device, which removes large impurities in the water flow, and the filtered water flows into the fine filter device, which removes fine impurities in the water flow, and the filtered water flows into the clean water tank for storage, and the water in the clean water tank enters the spray device, sprays and cools the return air entering from the air inlet pipe, and the treated return air is discharged from the air outlet pipe, and the sewage after spraying enters the sewage tank.

[0006] The coarse filtering device includes a support platform, which is installed on the spraying device, a cyclone tube is installed on the support platform, a first water inlet pipe is installed on one side of the cyclone tube, a siphon tube is installed inside the cyclone tube, one end of the siphon tube is installed on the fine filtering device, a slag discharge pipe is installed at one end of the cyclone tube, a slag discharge valve is installed in the slag discharge pipe, and the slag discharge valve is connected to the control system.

[0007] The siphon includes a siphon low section, one end of the siphon low section is connected to a siphon high section, one end of the siphon high section is connected to a siphon outlet section, one end of the siphon outlet section is connected to a drainage section, and one end of the drainage section is installed on a fine filtration device. Water flows into the cyclone from the first water inlet pipe. After the water enters the cyclone, a high-speed rotating eddy current will be formed. Large impurities are subjected to a strong centrifugal force and are forced to move outward and settle to the bottom, thereby achieving preliminary separation and filtration. When the water level in the cyclone rises to the siphon high section, the water will enter from the siphon low section, pass through the siphon high section to reach the siphon outlet section, and finally be discharged into the second water inlet pipe from the drainage section. When the water level drops to the siphon low section, the water flow stops, which can ensure that the suspended impurities in the water have enough time to settle, further improving the efficiency of the entire filtration process.

Water flows into the housing from the second water inlet pipe and enters the filter cylinder from the outside of the filter cylinder. The filter cylinder filters out the fine impurities in the water flow. The control system controls the first water pump to start, and the first water pump sucks the water flow inside the filter cylinder into the clean water tank through the water suction pipe.

[0009] The scraper structure includes a circular ring which is rotatably installed at the bottom of the housing. A support plate is installed inside the circular ring.

One end of the circular ring is installed with an L-shaped plate, and a brush is arranged on one side of the L-shaped plate. After using for a period of time, the first water pump drains the water inside the filter cylinder. Then, the control cylinder is started. The cylinder rod drives the filter cylinder to slide in the housing towards the direction close to the cylinder until the connecting column blocks the second water inlet pipe. At this time, the bottom of the filter cylinder leaves the circular ring, and at the same time, the abutting column pushes open the one-way valve. The water in the clean water tank flows from the backwash pipe to the connecting pipe, enters the inside of the filter cylinder from the connecting pipe. The water flows from the inside of the filter cylinder to the outside of the filter cylinder, quickly taking away the impurities deposited on the outside of the filter cylinder from the surface of the filter cylinder.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The coarse filtration device of the present invention adopts a cyclone tube. After the water flow enters the cyclone tube, a high-speed rotating eddy current will be formed. Large particles of impurities are subjected to a strong centrifugal force and are forced to move outward and settle to the bottom, thereby realizing preliminary separation and filtration. At the same time, a siphon tube is used to intermittently discharge the filtered water in the middle, prolonging the residence time of the water flow in the cyclone tube, enabling the suspended impurities therein to have sufficient time to settle, and further improving the efficiency of the entire filtration process;

[0017] 2. The fine filtration device of the present invention adopts a backwashing structure. After the filter cartridge is used for a period of time, it is inevitable that suspended particles, oil stains and other fine impurities from the fluid will accumulate on the surface of the filter cartridge. The filter cartridge is backwashed to quickly carry away the deposited impurities from the surface of the filter cartridge. At the same time, under the push of the backwashing water flow, the scraper structure moves smoothly along the surface of the filter cartridge, and the brush on the scraper plays its physical friction role to completely scrape off the stubborn dirt that is difficult to be washed away by the simple water flow due to surface tension or adhesion, realizing the all-round cleaning of the filter cartridge, which can extend the service life of the filter cartridge, reduce the equipment maintenance frequency and operation cost;

[0018] 3. The spray device of the present invention is driven by the kinetic energy of water flow. The spray head can rotate and swing simultaneously under the action of water flow, enabling the spray head to change the water outlet angle during operation, forming a continuously changing spray trajectory, ensuring that the sprayed water flow can cover the entire return air area, avoiding dead corners of missed spraying or insufficient spraying, and at the same time being able to increase the water flow rate according to the increase in temperature, accelerating the rotation and swing speed of the spray head, ensuring that the sprayed water mist acts on the air at a higher frequency and in a denser coverage manner, further promoting the evaporation and heat absorption of water, achieving faster cooling, and the speed of the drainage system will also be correspondingly increased to avoid excessive accumulation of water in the spray area and affecting the subsequent spray effect. This positive feedback mechanism enables the entire system to automatically adjust according to environmental changes. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment: As Figures 1-9 shown, the present invention provides a technical solution. The spray cooling device includes a spray device 6. An air inlet pipe 1 and a sewage tank 7 are installed at one end of the spray device 6, and an air outlet pipe 2 is installed at the other end of the spray device 6. Above the spray device 6, a coarse filtration device 3, a fine filtration device 4 and a bottom plate 8 are sequentially installed along the water flow direction, and a clean water tank 5 is installed on the bottom plate 8. Water flow enters the coarse filtration device 3, and the coarse filtration device 3 removes large particles of impurities in the water flow. The filtered water flow enters the fine filtration device 4, and the fine filtration device 4 removes small impurities in the water flow. The filtered water flow enters the clean water tank 5 for storage. The water flow in the clean water tank 5 enters the spray device 6 to spray and cool the return air entering from the air inlet pipe 1. The processed return air is discharged from the air outlet pipe 2, and the sprayed sewage enters the sewage tank 7.

A first water inlet pipe 33 is installed on one side of the cyclone cylinder 32. A siphon pipe 35 is installed inside the cyclone cylinder 32. One end of the siphon pipe 35 is installed on the fine filtration device 4. One end of the cyclone cylinder 32 is installed with a slag discharge pipe 34. A slag discharge valve is installed in the slag discharge pipe 34, and the slag discharge valve is connected to the control system.

One end of the drainage section 354 is installed on the fine filtration device 4. Water flows into the cyclone cylinder 32 from the first water inlet pipe 33. After the water enters the cyclone cylinder 32, a high-speed rotating eddy current will be formed. Large impurities are subjected to a strong centrifugal force and are forced to move outward and deposit at the bottom, thus realizing preliminary separation and filtration. When the water level in the cyclone cylinder 32 rises to the siphon high section 352, the water will enter from the siphon low section 351, pass through the siphon high section 352 to reach the siphon outlet section 353, and finally be discharged into the second water inlet pipe 45 from the drainage section 354. When the water level drops to the siphon low section 351, the water flow stops, which can ensure that the suspended impurities in the water have enough time to settle, further improving the efficiency of the entire filtration process.

One end of the circular ring 481 is installed with an L-shaped plate 484, and a brush is arranged on one side of the L-shaped plate 484.

[0035] After being used for a period of time, the first water pump 43 drains the water inside the filter cartridge 47. Then, the control cylinder 44 is started. The cylinder rod of the cylinder 44 drives the filter cartridge 47 to slide in the housing 42 towards the direction close to the cylinder 44 until the connecting column blocks the second water inlet pipe 45. At this time, the bottom of the filter cartridge 47 leaves the circular ring 481. Meanwhile, the abutting column pushes open the one-way valve, and the water in the clean water tank 5 flows from the backwash pipe 49 into the connecting pipe 41, and then enters the inside of the filter cartridge 47 from the connecting pipe 41. The water flows from the inside of the filter cartridge 47 to the outside of the filter cartridge 47, quickly taking away the impurities deposited on the outside of the filter cartridge 47 from the surface of the filter cartridge 47.

The other end of the second water pump is installed on the first water inlet pipe 33. The second water pump is connected to the control system. The second rotating shaft 651 drives the first gear 661 to rotate. The first gear 661 drives the belt 663 to rotate. The belt 663 drives the second gear 662 to rotate. The second gear 662 drives the screw rod 665 to rotate. The screw rod 665 transports the sewage after spraying to the sewage tank 7. After a period of time, the second water pump is controlled to start. The second water pump pumps the sewage in the sewage tank 7 into the first water inlet pipe 33, realizing the recycling of water and saving industrial water.

[0043] The working principle of the present invention:

[0044] The water flow of industrial water enters the cyclone tube 32 from the first water inlet pipe 33. After the water flow enters the cyclone tube 32, a high-speed rotating eddy current will be formed. Large impurities are subjected to a strong centrifugal force and are forced to move outward and deposit at the bottom, thus realizing preliminary separation and filtration. When the water level in the cyclone tube 32 rises to the siphon high section 352, the water flow will enter from the siphon low section 351, pass through the siphon high section 352 to reach the siphon outlet section 353, and finally be discharged to the second water inlet pipe 45 from the drainage section 354. When the water level drops to the siphon low section 351, the water flow stops flowing, which can ensure that the suspended impurities in the water flow have enough time to settle, further improving the efficiency of the entire filtration process.

[0045] The filtered water flow enters the housing 42 from the second water inlet pipe 45, enters the filter cartridge 47 from the outside of the filter cartridge 47, the filter cartridge 47 filters out the fine impurities in the water flow, the control system controls the first water pump 43 to start, and the first water pump 43 pumps the water flow inside the filter cartridge 47 into the clean water tank 5 through the water suction pipe 46.

[0046] After using for a period of time, the first water pump 43 pumps the water flow inside the filter cartridge 47 dry, controls the air cylinder 44 to start, the piston rod of the air cylinder 44 drives the filter cartridge 47 to slide in the housing 42 in the direction close to the air cylinder 44 until the connecting column blocks the second water inlet pipe 45. At this time, the bottom of the filter cartridge 47 leaves the circular ring 481, and at the same time, the abutting column pushes open the one-way valve, the water flow in the clean water tank 5 flows from the backwash pipe 49 into the connecting pipe 41, enters the inside of the filter cartridge 47 from the connecting pipe 41, the water flow flows from the inside of the filter cartridge 47 to the outside of the filter cartridge 47, quickly takes away the impurities deposited on the outside of the filter cartridge 47 from the surface of the filter cartridge 47, the cleaned sewage flows out from the sewage pipe, the sewage drives the first drainage fan 483 to rotate, the first drainage fan 483 drives the first rotating shaft 485 to rotate, the first rotating shaft 485 drives the support plate 482 to rotate, the support plate 482 drives the circular ring 481 to rotate, the circular ring 481 drives the L-shaped plate 484 to rotate around the filter cartridge 47, and the L-shaped plate 484 drives the brush to completely scrape off the stubborn dirt that is difficult to be washed away by the simple water flow due to surface tension or adhesion, realizing the all-round cleaning of the filter cartridge 47.

[0047] The filtered water flow enters the main spray pipe 62 and the auxiliary spray pipe 63 from the clean water tank 5. The water flow in the auxiliary spray pipe 63 is blocked by the plunger head. The water flow in the main spray pipe 62 drives the second drainage fan 652 to rotate, the second drainage fan 652 drives the second rotating shaft 651 to rotate, the second rotating shaft 651 drives the first bevel gear 653 to rotate, the first bevel gear 653 drives the second bevel gear 654 and the third bevel gear 6573 to rotate, the second bevel gear 654 drives the third rotating shaft 656 to rotate, the third rotating shaft 656 drives the universal joint 655 to rotate, the universal joint 655 drives the fourth rotating shaft to rotate, the fourth rotating shaft drives the nozzle seat to rotate, the nozzle seat drives the water flow in the nozzle to rotate, the third bevel gear 6573 drives the fifth rotating shaft 6574 to rotate, the fifth rotating shaft 6574 drives the cylinder to rotate, the cylinder drives the cam groove 6575 to drive, the cam groove 6575 drives the L-shaped cam 6576 to rotate around the fixed block 6572, one end of the L-shaped cam 6576 drives the nozzle housing 659 to swing, the nozzle housing 659 drives the nozzle seat and the corrugated pipe 658 to swing, the nozzle seat swings while rotating, which can change the water outlet angle of the nozzle, form a continuously changing spraying trajectory, ensure that the sprayed water flow can cover the entire return air area, and avoid the dead angle problems of missed spraying or insufficient spraying.

[0048] When the return air enters the interior of the box body 61 from the air inlet pipe 1, the water flow sprayed by the nozzle sprays and cools the return air. When the return air passes through the air inlet pipe, the bimetallic block 646 senses the temperature rise. The bimetallic block 646 will bend to one side, driving the limit block 645 to move. The limit block 645 drives the guide post 642 to slide away from the fixed plate 641 in the fixed plate 641. The guide post 642 drives the plunger 643 to move, and the plunger 643 drives the plunger head to move. The water flow flows from the secondary spray water pipe 63 to the main spray water pipe 62 to increase the water flow rate. At the same time, it drives the second drain fan 652 to rotate faster, accelerating the rotation and swinging speed of the nozzle, ensuring that the sprayed water mist acts on the air with a higher frequency and a denser coverage method, further promoting the evaporation and heat absorption of water, achieving faster cooling, and also improving the speed of the drainage system to avoid excessive accumulation of water in the spraying area and affecting the subsequent spraying effect. This positive feedback mechanism enables the entire system to automatically adjust according to environmental changes.

[0049] The return air after spray cooling is discharged from the air outlet pipe 2. The second rotating shaft 651 drives the first gear 661 to rotate. The first gear 661 drives the belt 663 to rotate. The belt 663 drives the second gear 662 to rotate. The second gear 662 drives the screw rod 665 to rotate. The screw rod 665 conveys the sprayed sewage to the sewage tank 7. After a period of time, the industrial water supply to the first water inlet pipe 33 is stopped, and the second water pump is controlled to start. The second water pump pumps the sewage in the sewage tank 7 into the first water inlet pipe 33 to realize the recycling of water and save industrial water.
