Description

Technical Field

[0001] The present application relates to the technical field of heat exchangers, and in particular to a high-efficiency and energy-saving tubular heat exchanger. Background Art

[0002] The tubular heat exchanger is mainly composed of a shell, a tube bundle, a tube sheet and a head. The shell is mostly circular and contains parallel tube bundles. Both ends of the tube bundle are fixed on the tube sheet. The two fluids that exchange heat in the tubular heat exchanger, one flows in the tube, and its stroke is called the tube pass.

[0003] When a tubular heat exchanger is in use, condensed water is usually required to cool the heat source in the heat exchanger for heat exchange. For example, a Chinese patent with publication number CN111521048A in the relevant technology proposes a rotating cylinder water cooling device, which has a motor driving the tube group structure to rotate as a whole, so that all the heat dissipation tubes rotate around the axis of the second cylinder. At the same time, the first spray hole and the second spray hole synchronously spray water toward the tube group structure to achieve heat exchange with the medium flowing through the heat dissipation tube, thereby achieving cooling of the medium. In this process, water is in full contact with the heat dissipation tube, thereby greatly improving the utilization rate of cooling water and improving the heat dissipation efficiency.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the tubular heat exchanger is working in a factory, the temperature of the outer wall of the heat exchanger will gradually increase due to the ambient temperature of the factory and the drive of the heat exchange system inside the heat exchanger. Long-term use will affect the heat exchange effect of the heat source in the heat exchanger. Therefore, a cooling system needs to be set up to cool the outer wall of the heat exchanger. However, this technology is not convenient for measuring the temperature while the outer wall of the heat exchanger is being cooled, and it is not convenient to adjust the amount of liquid water sprayed according to the temperature at different positions on the outer wall of the heat exchanger. If the temperature of the outer wall of the heat exchanger is too high and the amount of liquid sprayed is too low, it will affect the cooling effect of the outer wall of the heat exchanger. If the temperature of the outer wall of the heat exchanger is too low and the amount of liquid sprayed is too high, it will cause a waste of water resources and affect the energy-saving effect of the heat exchanger. It is inconvenient to use and cannot guarantee the performance and effect of the tubular heat exchanger. Summary of the invention

[0005] In order to solve the problem that it is inconvenient to measure the temperature while the outer wall of the heat exchanger is cooling, and thus it is inconvenient to adjust the amount of liquid water sprayed according to the temperature at different positions on the outer wall of the heat exchanger, the present application provides a high-efficiency and energy-saving tubular heat exchanger.

[0006] The present application provides a high-efficiency and energy-saving tubular heat exchanger adopts the following technical solution:

[0007] A high-efficiency and energy-saving tubular heat exchanger, comprising a heat exchanger body, a heat insulation box arranged on the outside of the heat exchanger body, and a drive box arranged on the heat insulation box, wherein a processing mechanism for scraping, spraying, blowing and measuring the temperature of the outer wall of the heat exchanger body is arranged on the inner side of the heat insulation box, and the processing mechanism comprises a scraping and brushing component, a water spraying component, a blowing component and a temperature measuring component, and the temperature measuring component can control the water volume of the water spraying component; an adjusting component for rotating and adjusting the scraping and brushing component, a cooling component and a temperature measuring component is arranged on the heat exchanger body; a storage mechanism for recovering and filtering condensed water is arranged on the outside of the heat exchanger body; the scraping and brushing component comprises two scraping and brushing plates rotatably arranged on the outside of the heat exchanger body and An adjusting member for rotationally adjusting the two scraping brush plates, wherein the two scraping brush plates are movably fitted with the outer wall of the heat exchanger body; the water spraying assembly comprises two fixed square tubes rotatably arranged on the outer side of the heat exchanger body and a water supply member for supplying water to the two fixed square tubes; the temperature measuring assembly comprises two adjusting blocks rotatably arranged on the outer side of the heat exchanger body and adjusting plates respectively sliding through the inner sides of the two fixed square tubes, a liquid gap is arranged between the left side of the adjusting plate and the inner side of the fixed square tube, the adjusting block will expand at high temperature and contract at low temperature, so that the adjusting block can drive the adjusting plate to translate due to temperature changes to control the size of the liquid gap inside the fixed square tube.

[0008] By adopting the above technical scheme, the outer surface of the heat exchanger body can have a heat-insulating effect through the heat insulation box, so as to avoid the influence of the temperature outside the factory on the heat exchange of the heat exchanger body, so as to enhance the heat exchange effect between the condensed water and the hot raw material inside the heat exchanger body. The bidirectional motor, two drive shafts and two power gears can be hidden and stored through the drive box. The outer surface of the heat exchanger body can be sprayed with water for cooling through the water spray assembly, so as to reduce the temperature of the outer surface of the heat exchanger body and prevent the external temperature from interfering with the heat exchange between the condensed water and the hot raw material inside the heat exchanger body. It can avoid the outer surface of the heat exchanger body from transferring heat to the inner side of the heat exchanger body due to excessive temperature, so as to ensure the heat exchange effect of the outer surface of the heat exchanger body and at the same time, dissipate heat and cool the heat exchanger body.

[0009] The outer surface of the heat exchanger body can be scraped and brushed by the scraping and brushing assembly to prevent the condensed water from scaling and adhering to the outer side of the heat exchanger body when the water spray assembly sprays water to cool the heat exchanger body. At the same time, it can prevent the condensed water from spraying the heat exchanger body for a long time and causing corrosion and cracking of the heat exchanger body. The temperature of the outer surface of the heat exchanger body can be detected by the temperature measuring assembly. At the same time, the temperature measuring assembly can control the water flow rate of the water spray assembly. When the temperature of the outer surface of the heat exchanger body increases, the regulating block will expand due to the high temperature. When the temperature of the outer surface of the heat exchanger body decreases, the regulating block will shrink due to the low temperature. Therefore, the expansion and contraction of the regulating block will change with the change of the outer surface temperature of the heat exchanger body. The expansion of the regulating block can enlarge the gap inside the fixed square tube and increase the water flow rate of the fixed square tube. The contraction of the regulating block can drive the regulating plate to Moving it right can reduce the gap inside the fixed square tube, reduce the water flow rate of the fixed square tube, and spray cooling the outer surface of the heat exchanger body with a normal amount of water, which can reduce the utilization rate of condensed water. The outer surface of the heat exchanger body can be cooled by blowing through the blowing mechanism, and the effect of blowing cooling on the outside of the heat exchanger body can be enhanced by spraying condensed water. The positions of the scraping and brushing components, the cooling components and the temperature measuring components can be adjusted through the adjusting components, and the speed and effect of scraping, spraying cooling and measuring the temperature of the outer surface of the heat exchanger body by the scraping and brushing components, the cooling components and the temperature measuring components can be used to control the speed and effect of scraping, spraying cooling and measuring the temperature of the outer surface of the heat exchanger body. The used condensed water on the inside of the heat exchanger body can be filtered, purified and stored through the storage mechanism. At the same time, the condensed water sprayed on the outer surface of the heat exchanger body by the inside of the insulation box can also be collected, filtered and purified, which can reduce the waste of water resources and ensure the energy-saving effect of the heat exchanger body.

[0011] By adopting the above technical solution, because the two adjusting blocks are respectively attached to the outside of the heat exchanger body, when the temperature of the outer surface of the heat exchanger body increases, the adjusting blocks will expand due to the high temperature, and when the temperature of the outer surface of the heat exchanger body decreases, the adjusting blocks will shrink due to the low temperature. The expansion and contraction of the two adjusting blocks will respectively drive the two movable push plates and the two movable rollers to move up and down. The two sets of telescopic springs can make the two movable cone blocks have a buffering effect. When the two movable rollers move up and down, they will respectively drive the two movable cone blocks, the two adjusting plates and the two limit plates to move left and right. The two adjusting plates move left and right on the inner sides of the two fixed square tubes respectively. The size of the gap inside the two fixed square tubes can be controlled to control the flow rate of condensed water inside the two fixed square tubes. When the temperature of the outer surface of the heat exchanger body is too high, the expansion of the adjusting block can drive the adjusting plate to move to the left, so that the gap inside the fixed square tube can be enlarged and the water flow rate of the fixed square tube can be increased. When the temperature of the outer surface of the heat exchanger body is too low, the contraction of the adjusting block can drive the adjusting plate to move to the right, so that the gap inside the fixed square tube can be reduced and the water flow rate of the fixed square tube can be reduced to ensure that the sprinkler head sprays and cools the outer surface of the heat exchanger body with a normal amount of water, thereby reducing the use rate of condensed water and avoiding the waste of condensed water as much as possible.

[0013] By adopting the above technical scheme, the two movable cone blocks can have a buffering effect through the two sets of telescopic springs, and because the two movable rollers are respectively movably fitted with the inclined surfaces of the two movable cone blocks, when the two movable rollers move up and down, the two movable cone blocks, the two adjustment plates and the two limit plates can be guaranteed to move left and right through the cooperation of the two movable rollers and the inclined surfaces of the two movable cone blocks and the buffering effect of the two sets of telescopic springs. The two movable cone blocks can be limited respectively by the two movable pulleys and the two pulley grooves to ensure the stability of the left and right movement of the two movable cone blocks. The two adjustment blocks can be hidden and stored respectively by the two fixed covers, so as to avoid condensed water spraying on the two adjustment blocks when the two sets of sprinkler heads cool the outer surface of the heat exchanger body. At the same time, it can be avoided that the temperature of the condensed water interferes with the adjustment blocks when the two adjustment blocks cool the heat exchanger body, and the adjustment blocks can be isolated from the temperature outside the fixed cover to ensure the temperature measurement effect of the two adjustment blocks on the heat exchanger body.

[0014] Optionally, the scraper assembly includes two fixed boxes rotatably arranged on the outside of the heat exchanger body, buffer springs fixed on the inside of the two fixed boxes, and buffer plates arranged on the outside of the buffer springs.

Connecting plates are arranged on the left and right sides of the two fixed boxes, and the two fixed covers are respectively fixedly connected to the two connecting plates on the right side.

[0015] By adopting the above technical scheme, when the scraper assembly is driven by the adjusting assembly to rotate about 180 degrees, the two fixed boxes, two sets of buffer springs, two buffer plates, and two scraper plates can be driven to rotate about 180 degrees respectively. When the two scraper plates rotate about 180 degrees, the outer surface of the heat exchanger body can be scraped and brushed to prevent condensed water from spraying and cooling the outer side of the heat exchanger body for a long time, scaling and adhesion on the outer side of the heat exchanger body, and at the same time, it can prevent condensed water from spraying on the heat exchanger body for a long time, causing corrosion and cracking of the heat exchanger body.

[0016] Optionally, the water supply component includes a water pump arranged on the outside of the heat exchanger body, a water pump pipe is arranged at the inlet of the water pump, a fixed pipe is arranged at the outlet of the water pump, two telescopic hoses are arranged on the outside of the fixed pipe, the two telescopic hoses are respectively fixedly connected to two fixed square tubes, and sprinkler heads are arranged on the outside of the two fixed square tubes. The number of the sprinkler heads is two groups, and the number of the sprinkler heads in each group is six.

[0017] By adopting the above technical scheme, the condensed water can be sequentially pumped into the inner sides of the water pump, the fixed pipe, the two telescopic hoses, the two fixed square tubes and the two groups of sprinkler heads through the water pump. The two groups of sprinkler heads will spray the condensed water on the outside of the heat exchanger body respectively. The two groups of sprinkler heads can spray the condensed water in multiple ranges to ensure the cooling and heat dissipation effect of the outside of the heat exchanger body. At the same time, when the adjusting component drives the water spray component to rotate about 180 degrees, it can drive the two fixed square tubes and the two groups of sprinkler heads to rotate about 180 degrees respectively, so that the two groups of sprinkler heads can spray and cool the outside of the heat exchanger body in multiple ranges, which can enhance the cooling effect of the heat exchanger body. The two telescopic hoses can make the two fixed square tubes have a telescopic effect, so as to avoid the two telescopic hoses interfering with the angular rotation of the two fixed square tubes when the two fixed square tubes are rotating forward or reverse.

[0018] Optionally, the adjustment component includes a bidirectional motor fixed on the heat insulation box, the output shafts on the left and right sides of the bidirectional motor are provided with drive shafts, the outer sides of the two drive shafts are provided with power gears, the outer sides of the two power gears are meshed with transmission gears, the inner sides of the two transmission gears are provided with movable rings, the two fixed square tubes are fixedly connected to the two movable rings, the two connecting plates on the left are fixedly connected to the left movable ring, and the two fixed covers are fixedly connected to the right movable ring.

[0019] By adopting the above technical scheme, the two driving shafts and the two power gears can be frequently driven by the bidirectional motor to rotate about 180 degrees respectively. Because the two power gears are respectively engaged with the two transmission gears, when the two power gears rotate about 180 degrees, they can respectively drive the two transmission gears, two movable rings, two fixed square tubes, two groups of sprinkler heads, two fixed boxes, two buffer plates, two scraping plates, two fixed covers, two adjusting blocks, two movable push plates, two movable rollers, two groups of telescopic springs, two movable cone blocks, two adjusting plates and two limit plates to rotate about 180 degrees, which can ensure the range of scraping, temperature measurement and cooling of the outside of the heat exchanger body.

[0021] By adopting the above technical solution, when the bidirectional motor frequently drives the two drive shafts to rotate about 180 degrees, it will also frequently drive the four first bevel gears to rotate forward and reverse to a certain extent. Because the four first bevel gears are respectively meshed with the four second bevel gears, when the four second bevel gears rotate, they will frequently drive the four movable shafts and the four fan blades to rotate forward and reverse respectively. When the four fan blades frequently rotate forward and reverse, wind force will be generated. The frequent fluttering of wind force on the outside of the heat exchanger body can enhance the cooling effect of the outside of the heat exchanger body. In addition, in combination with the spraying of condensed water by two sets of sprinkler nozzles and the frequent fluttering of wind force, the speed and effect of cooling the outer surface of the heat exchanger body can be guaranteed.

The particles and impurities will flow on the inner side of the filter frame, and the condensed water will flow through the filter holes to the activated carbon adsorption plate, and then the harmful substances in the condensed water can be adsorbed and purified by the activated carbon adsorption plate, so as to ensure the quality of the condensed water. Finally, the purified condensed water will flow to the inner bottom wall of the storage box for storage, so as to facilitate the recovery of the condensed water.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. Pour the hot raw material into the two heat source chambers and multiple heat exchange tubes in the heat exchanger body through the feed pipe, and then pour the condensed water into the two partition circular plates in the heat exchanger body through the liquid inlet pipe, so as to separate the condensed water from the hot raw material. The flow of condensed water can make the condensed water and the hot raw material exchange heat. The chiller and the cold water pipe can reduce the temperature of the condensed water, which can enhance the heat exchange effect between the condensed water and the hot raw material. The stop valve can be opened to put the used condensed water inside the heat exchanger body into the inner side of the storage box through the liquid outlet pipe. The particles and impurities in the condensed water can be separated from the condensed water through the filter frame. The particles and impurities will flow on the inner side of the filter frame. The condensed water will flow to the activated carbon adsorption plate through the filter hole. The harmful substances in the condensed water can be adsorbed and purified by the activated carbon adsorption plate. The purified condensed water will flow to the inner bottom wall of the storage box for storage, so as to facilitate the recovery of the condensed water.

[0030] 2. The purified condensed water inside the storage box can be pumped into the pumping pipe, the fixed pipe, two telescopic hoses, two fixed square tubes and the inside of two groups of sprinkler heads in sequence through the water pump. The two groups of sprinkler heads will spray the condensed water on the outside of the heat exchanger body respectively. The two groups of sprinkler heads can spray the condensed water in a multi-range to ensure the cooling and heat dissipation effect of the outside of the heat exchanger body. The two-way motor can frequently drive the two drive shafts and two power gears to rotate about 180 degrees, and then drive the two transmission gears, two movable rings, two fixed square tubes, two groups of sprinkler heads, two fixed boxes, two buffer plates, two scraper plates, two fixed covers, two adjustment blocks, two movable push plates, two movable rollers, two groups of telescopic springs, two movable cone blocks, two adjustment plates and two limit switches. The plate can be rotated about 180 degrees to adjust the angles of the two groups of sprinkler heads, so that the two groups of sprinkler heads can spray and cool the outside of the heat exchanger body in a multi-range, which can enhance the cooling effect of the heat exchanger body. The outer surface of the heat exchanger body can be scraped and brushed when the two scraper plates are rotated about 180 degrees to avoid condensed water spraying and cooling the outside of the heat exchanger body for a long time, scaling and adhesion on the outside of the heat exchanger body, and corrosion and cracking of the heat exchanger body caused by condensed water. Through the cooperation between the two fixed boxes, the two groups of buffer springs and the two buffer plates, the two scraper plates can have a buffering and shock-absorbing effect, and the two scraper plates can be stably attached to the heat exchanger body, avoiding the two scraper plates from damaging the outer surface of the heat exchanger body due to excessive scraping force;

[0031] 3. Because the two adjusting blocks are respectively attached to the outside of the heat exchanger body, the temperature of the outer surface of the heat exchanger body can be detected through the two adjusting blocks. When the temperature of the outer surface of the heat exchanger body increases, the adjusting block will expand due to the high temperature. When the temperature of the outer surface of the heat exchanger body decreases, the adjusting block will shrink due to the low temperature. Therefore, the expansion and contraction of the adjusting block will change with the change of the outer surface temperature of the heat exchanger body. The expansion and contraction of the two adjusting blocks will respectively drive the two movable push plates and the two movable rollers to move up and down. The two sets of telescopic springs can make the two movable cone blocks have a buffering effect. Because the two movable rollers are respectively movably attached to the inclined surfaces of the two movable cone blocks, when the two movable rollers move up and down, they will respectively drive the two movable cone blocks, the two adjusting plates and the two limit plates to move left and right, so as to control the size of the gap inside the two fixed square tubes, so as to control the flow rate of the condensed water inside the two fixed square tubes. When the temperature of the outer surface of the heat exchanger body is too high, the expansion of the adjusting block can drive the adjusting plate to move to the left, so as to enlarge the gap inside the fixed square tube and improve the fixed The water flow rate of the square tube can ensure the effect of the sprinkler head spraying and cooling the outer surface of the heat exchanger body. When the temperature of the outer surface of the heat exchanger body is too low, the contraction of the adjustment block can drive the adjustment plate to move to the right, which can reduce the gap inside the fixed square tube and reduce the water flow rate of the fixed square tube to ensure that the sprinkler head sprays and cools the outer surface of the heat exchanger body with a normal amount of water, which can reduce the use rate of condensed water and try to avoid wasting condensed water to improve the effect of spraying and cooling the outer surface of the heat exchanger body. Two sets of sprinkler heads When the outer surface of the heat exchanger body is sprayed for cooling, the condensed water will eventually flow to the inner bottom wall of the insulation box due to its weight. The condensed water used inside the insulation box can be put into the inner side of the storage box again through the connecting pipe by adjusting the control valve, and the condensed water is filtered and purified by the filter frame and the activated carbon adsorption plate. The condensed water can be recycled again to ensure the energy-saving effect of the heat exchanger body. The temperature can be measured while the outer wall of the heat exchanger is cooled. The amount of liquid water sprayed can be adjusted according to the temperature at different positions of the outer wall of the heat exchanger.

[0032] 4. When the two fixed covers and the two adjustment blocks rotate about 180 degrees at the same time, the two adjustment blocks can perform multi-range detection on the outer surface of the heat exchanger body. The amount of water inside the two fixed square tubes can be adjusted according to the different positions of the outer surface of the heat exchanger body to improve the effect of water spray cooling on the outer surface of the heat exchanger body. At the same time, when the two fixed covers rotate about 180 degrees respectively, the two scraping plates can be used to scrape and clean the outer surface of the heat exchanger body to ensure the range and effect of scraping and cleaning the outer surface of the heat exchanger body. When the two-way motor frequently drives the two drive shafts to rotate about 180 degrees, it will also frequently drive the four first bevel gears, the four second bevel gears, the four movable shafts and The four fan blades rotate forward and reverse. When the four fan blades rotate forward and reverse frequently, wind will be generated. The wind frequently flutters on the outside of the heat exchanger body, which can enhance the cooling effect of the outside of the heat exchanger body. In addition, the spraying of condensed water by two sets of sprinkler nozzles and the frequent fluttering of wind can ensure the speed and effect of cooling the outer surface of the heat exchanger body. The condensed water discharged from the tubular heat exchanger can be recycled to avoid wasting water resources and avoiding the influence of the heat exchange effect of the heat source inside the heat exchanger due to the ambient temperature of the factory and the drive of the heat exchange system of the heat exchanger when the tubular heat exchanger is used in the factory. It can also avoid damage to the components of the heat exchanger and prevent workers from touching the heat exchanger and getting burned. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] The implementation principle of an efficient and energy-saving tubular heat exchanger in the embodiment of the present application is:

[0061] By opening the connection cover, the hot raw material can be poured into the inner side of the heat exchanger body 1 through the feed pipe 43, and the hot raw material will flow into the two heat source chambers and multiple heat exchange tubes 40 inside the heat exchanger body 1. By opening the movable cover, the condensed water can be poured into the inner side of the heat exchanger body 1 through the liquid inlet pipe 44, and the condensed water will flow into the cooling chamber between the two partition circular plates 39, thereby separating the condensed water from the hot raw material, and allowing the condensed water to cover the outer surface of each heat exchange tube 40. Through the flow of the condensed water, the condensed water and the hot raw material can be heat exchanged. The temperature of the condensed water can be reduced through the chiller 55 and the cold water pipe 56, thereby enhancing the heat exchange effect between the condensed water and the hot raw material. By adjusting the fixed valve 42, the hot raw material that has been heat exchanged inside the heat exchanger body 1 can be discharged through the discharge pipe 41;

[0062] By opening the stop valve 34, the condensed water cooled by the chiller 55 and the cold water pipe 56 inside the heat exchanger body 1 can be put into the inner side of the storage box 32 through the liquid outlet pipe 33, and the condensed water can be filtered by the filter frame 36, so that the particles and impurities in the condensed water can be separated from the condensed water, and the particles and impurities will flow on the inner side of the filter frame 36, and the condensed water will flow to the activated carbon adsorption plate 38 through the filter hole, and then the harmful substances in the condensed water can be adsorbed and purified by the activated carbon adsorption plate 38, so as to ensure the quality of the condensed water, and finally the purified condensed water will flow to the inner bottom wall of the storage box 32 for storage, so as to recover the condensed water, and the sealing cover can also be opened to add condensed water to the inner side of the storage box 32 through the collecting pipe 48, and the particles and impurities inside the filter frame 36 can be cleaned regularly by opening the sealing door 52, and the activated carbon adsorption plate 38 can be replaced regularly to ensure the effect of filtering and purifying the condensed water;

[0063] The purified condensed water inside the storage box 32 can be pumped into the pumping pipe 15, the fixed pipe 16, the two telescopic hoses 17, the two fixed square pipes 18 and the inside of the two groups of sprinkler heads 19 in sequence through the pumping pump 14. The two groups of sprinkler heads 19 will spray the condensed water on the outside of the heat exchanger body 1 respectively. The two groups of sprinkler heads 19 can spray the condensed water in multiple ranges, which can ensure the cooling and heat dissipation effect of the outside of the heat exchanger body 1.

[0064] At the same time, the two-way motor 4 can frequently drive the two driving shafts 5 and the two power gears 6 to rotate about 180 degrees. Because the two power gears 6 are meshed with the two transmission gears 7 respectively, when the two power gears 6 rotate about 180 degrees, they can respectively drive the two transmission gears 7, the two movable rings 8, the two fixed square tubes 18, the two groups of sprinkler heads 19, the two fixed boxes 9, the two buffer plates 11, the two scraper plates 12, the two fixed covers 20, the two adjustment blocks 21, the two movable push plates 22, the two movable rollers 23, the two groups of telescopic springs 24, the two movable cone blocks 25, the two adjustment plates 26 and the two limit plates 27 to rotate about 180 degrees, so that the angles of the two groups of sprinkler heads 19 can be adjusted, so that the two groups of sprinkler heads 19 can perform multi-range spray cooling on the outside of the heat exchanger body 1, which can enhance the cooling effect of the heat exchanger body 1;

[0065] When the two scraping and brushing plates 12 rotate about 180 degrees, the outer surface of the heat exchanger body 1 can be scraped and brushed to prevent the condensed water from spraying and cooling the outer side of the heat exchanger body 1 for a long time, causing scaling and adhesion on the outer side of the heat exchanger body 1, and also preventing the condensed water from spraying the heat exchanger body 1 for a long time, causing corrosion and cracking of the heat exchanger body 1;

[0066] Through the cooperation between the two fixing boxes 9, the two groups of buffer springs 10 and the two buffer plates 11, the two scraping and brushing plates 12 can have a buffering and shock absorbing effect, and the two scraping and brushing plates 12 can be stably attached to the top of the heat exchanger body 1. At the same time, the two scraping and brushing plates 12 can be prevented from damaging the outer surface of the heat exchanger body 1 due to excessive scraping force, and the two scraping and brushing plates 12 can ensure the effect of scraping and cleaning the outer surface of the heat exchanger body 1;

[0067] Because the two adjustment blocks 21 are respectively attached to the outside of the heat exchanger body 1, the temperature of the outer surface of the heat exchanger body 1 can be detected through the two adjustment blocks 21. When the temperature of the outer surface of the heat exchanger body 1 increases, the adjustment block 21 will expand due to the high temperature. When the temperature of the outer surface of the heat exchanger body 1 decreases, the adjustment block 21 will shrink due to the low temperature. Therefore, the expansion and contraction of the adjustment block 21 will change with the change of the temperature of the outer surface of the heat exchanger body 1. The expansion and contraction of the two adjustment blocks 21 will respectively drive the two movable push plates 22 and the two movable rollers 23 to move up and down. The telescopic spring 24 can make the two movable cone blocks 25 have a buffering effect. Because the two movable rollers 23 are respectively in contact with the inclined surfaces of the two movable cone blocks 25, when the two movable rollers 23 move up and down, they will respectively drive the two movable cone blocks 25, the two adjustment plates 26 and the two limit plates 27 to move left and right. By moving the two adjustment plates 26 left and right on the inside of the two fixed square tubes 18, the size of the gap on the inside of the two fixed square tubes 18 can be controlled to control the flow rate of the condensed water on the inside of the two fixed square tubes 18. When the temperature of the outer surface of the heat exchanger body 1 is too high, the adjustment plate 26 can be used to adjust the flow rate of the condensed water on the inside of the two fixed square tubes 18. The expansion of the node block 21 can drive the adjustment plate 26 to move to the left, and the gap inside the fixed square tube 18 can be enlarged, and the water flow rate of the fixed square tube 18 can be increased to ensure the effect of the sprinkler head 19 spraying and cooling the outer surface of the heat exchanger body 1. When the temperature of the outer surface of the heat exchanger body 1 is too low, the contraction of the adjustment block 21 can drive the adjustment plate 26 to move to the right, and the gap inside the fixed square tube 18 can be reduced, and the water flow rate of the fixed square tube 18 can be reduced to ensure that the sprinkler head 19 sprays and cools the outer surface of the heat exchanger body 1 with a normal amount of water, which can reduce the use rate of condensed water and minimize the heat exchanger body 1. The amount of condensed water is avoided to improve the effect of spraying and cooling the outer surface of the heat exchanger body 1. When the two groups of sprinkler heads 19 spray and cool the outer surface of the heat exchanger body 1, the condensed water will finally flow to the inner bottom wall of the heat insulation box 2 due to its weight. By adjusting the control valve 54, the condensed water used inside the heat insulation box 2 can be put into the inner side of the storage box 32 again through the connecting pipe 53, and the condensed water can be filtered and purified by the filter frame 36 and the activated carbon adsorption plate 38. The condensed water can be recycled again, which can reduce the waste of water resources and ensure the energy-saving effect of the heat exchanger body 1.

[0068] At the same time, when the two fixed covers 20 and the two adjustment blocks 21 rotate about 180 degrees, the two adjustment blocks 21 can perform multi-range detection on the outer surface of the heat exchanger body 1, and can adjust the amount of water inside the two fixed square tubes 18 according to the different positions of the outer surface of the heat exchanger body 1, so as to improve the effect of water spray cooling on the outer surface of the heat exchanger body 1. At the same time, when the two fixed covers 20 rotate about 180 degrees, the two scraping plates 12 can be used to scrape and clean the outer surface of the heat exchanger body 1, so as to ensure the range and effect of scraping and cleaning the outer surface of the heat exchanger body 1.

[0069] When the bidirectional motor 4 frequently drives the two driving shafts 5 to rotate about one hundred and eighty degrees, it will also frequently drive the four first bevel gears 28 to rotate forward and reverse to a certain extent. Because the four first bevel gears 28 are respectively meshed with the four second bevel gears 29, when the four first bevel gears 28 rotate, they will frequently drive the four second bevel gears 29, the four movable shafts 30 and the four fan blades 31 to rotate forward and reverse respectively. When the four fan blades 31 frequently rotate forward and reverse, wind force will be generated. The frequent fluttering of wind force on the outside of the heat exchanger body 1 can enhance the cooling effect of the outside of the heat exchanger body 1, and the spraying of condensed water by the two groups of sprinkler heads 19 and the frequent fluttering of wind force can ensure the speed and effect of cooling the outer surface of the heat exchanger body 1.

[0070] The overall structure is simple and easy to use. The condensed water discharged from the tubular heat exchanger can be recycled. There is no need to discharge or discard the condensed water, which avoids wasting water resources and preventing stains mixed in the condensed water from affecting the factory environment. When the tubular heat exchanger is used in the factory, the factory's ambient temperature and the drive of the heat exchange system of the heat exchanger will not affect the heat exchange effect of the heat source inside the heat exchanger, and damage to the components of the heat exchanger will be avoided. The staff will be prevented from touching the heat exchanger and getting scalded. The temperature can be measured while the outer wall of the heat exchanger is cooling. The amount of liquid water sprayed can be adjusted according to the temperature at different positions on the outer wall of the heat exchanger, so as to avoid the outer wall of the heat exchanger being too high and the amount of liquid sprayed being too low, affecting the cooling effect of the outer wall of the heat exchanger, and preventing the outer wall of the heat exchanger from being too low and the amount of liquid sprayed being too high, causing waste of water resources, ensuring the energy-saving effect of the heat exchanger, and ensuring the performance and effect of the tubular heat exchanger.

[0071] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
