Description

Technical Field

[0001] The present invention relates to the technical field of coolers, in particular to a low-noise explosion-proof air-to-air cooler for an offshore platform. Background Art

[0002] The main function of wind turbines on offshore platforms is to generate electricity by utilizing abundant wind energy resources at sea, providing partial power support for offshore platforms, helping to reduce dependence on traditional energy sources and achieve energy conservation and emission reduction. During the operation of the wind turbine itself, some of its internal components will generate heat. If they are not cooled in time, their working efficiency and service life will be affected. Air-to-air coolers can help wind turbines dissipate this heat and maintain their good working condition.

[0003] Prior art, such as patent publication number CN116950860A, discloses a high-power, semi-direct-drive air-to-air cooler for offshore use. This cooler, comprising a generator compartment, a gas transmission assembly, a heat dissipation assembly, an exhaust assembly, a treatment assembly, and a water-cooling assembly, is described. In operation, the present invention discharges air into a tubular reactor through an exhaust pipe and a connecting pipe. The inner wall of the tubular reactor is coated with titanium dioxide, which absorbs hydrocarbons and phenols in oil fumes. A UV lamp is activated, generating ultraviolet light that irradiates the titanium dioxide coating, decomposing the hydrocarbons and phenols into harmless carbon dioxide and water, thereby treating the oil fumes in the air. Air then flows along the inner wall of the tubular reactor toward the air outlet, allowing the titanium dioxide to fully absorb the hydrocarbons and phenols in the oil fumes, improving the treatment effect. The air is then discharged through the air outlet to a filter screen, which removes particulate impurities.

[0004] Usually, after an air-to-air cooler has been used for a long time, dust impurities in the external air and oily impurities emitted in the air by other equipment will gradually deposit on the surface of the pipe during the heat exchange process. The putty on the surface of the pipe will reduce the heat exchange efficiency, so it needs to be cleaned. The common cleaning method now is to flush with a water gun. If you want to flush the putty that is difficult to remove, you need to pressurize the water gun. However, pressurized pipes can bend and the pipes can be partially bent and sunken, which will cause pipe leakage, thereby increasing maintenance costs and risks. Therefore, it is necessary to reduce the accumulation of putty on the pipe surface.

[0005] Therefore, we proposed a low-noise explosion-proof air-to-air cooler for offshore platforms to solve the above problems. Summary of the Invention

[0019] 3. When in use, installing the silencer at the air inlet pipe will slow down the inhaled air flow rate to a certain extent. The multiple silencer buckets inside the silencer are bucket-shaped. After the external air enters the silencer through the trumpet-shaped end of the silencer, the sound waves pass through each silencer bucket in turn, thereby slowing down the air flow rate and attenuating the noise waves generated when the air is inhaled, thereby achieving the effect of reducing noise. The sound-absorbing sleeve is made of sound-absorbing material, which can absorb the sound generated when the air quickly enters the silencer, thereby enhancing the noise reduction effect. At the same time, installing the noise reduction component at one end of the air inlet pipe can avoid excessive air flow speed and reduce the possibility of static electricity generated by air flow friction on the inner wall of the air inlet pipe, thereby effectively avoiding explosions caused by static electricity and improving safety. The silencer pipe is supported and fixed by a support frame. BRIEF DESCRIPTION OF THE DRAWINGS

The multiple cleaning rings 710 are evenly divided into four groups, and the outer surfaces of each group of cleaning rings 710 are fixedly connected with a connecting frame 709, and both ends of each connecting frame 709 are fixedly connected with a fixed block 705. A connecting rod 706 is fixedly connected between the opposite inner walls of each two adjacent fixed blocks 705. One end of each reinforcing rod 708 is fixedly connected to the corresponding fixed block 705. The tops of the two fixed cylinders 701 are fixedly connected to the first exhaust port 702 near one end, and the tops of the two fixed cylinders 701 are fixedly connected to the second exhaust port 707 near the other end. The air cooler assembly 1 includes a mounting frame 10 1. A plurality of heat exchange tubes 106 for the flow of heat exchange medium are embedded between the opposite inner walls of the mounting frame 101, and a guide tube 105 is fixedly connected between one end of each two vertically adjacent heat exchange tubes 106. Each cleaning ring 710 is slidably sleeved on the outside of each heat exchange tube 106. A connecting box 107 is fixedly installed at one end of the mounting frame 101. The outer surface of the connecting box 107 is fixedly connected to an air inlet pipe 108 near the top. The outer surface of the connecting box 107 is fixedly connected to an air outlet pipe 110 near the bottom. A main valve 109 is provided on the outer surface of the air outlet pipe 110. The outer surface of the connecting box 107 is fixedly connected to a fixing plate 111. A fan 112 is provided at the bottom of the fixing plate 111. The air delivery end of the fan 112 is connected to the air outlet pipe 110. One end is fixedly connected, and the pneumatic component 4 includes two air supply pipes 401, and the two air supply pipes 401 are fixedly connected to the two sides of the air outlet pipe 110 respectively. The outer surface of the two air supply pipes 401 is provided with a main control valve 402, and one end of the two air supply pipes 401 is fixedly connected with a U-shaped diverter pipe 403, and one end of the two diverter pipes 403 is fixedly connected with a first flow pipe 407, and one end of the two first flow pipes 407 is fixedly connected with one end of the two first exhaust ports 702 respectively. The outer surface of the other end of the two diverter pipes 403 is provided with a second one-way valve 405, and the other end of the two diverter pipes 403 is fixedly connected with a second flow pipe 406.One end of the two second flow pipes 406 is fixedly connected to one end of the two second exhaust ports 707 respectively.

[0024] In this embodiment, when in use, after the heat exchange tube 106 completes its work, its surface needs to be cleaned in time. At this time, the main valve 109 is closed, so that the airflow generated by the operation of the fan 112 is dispersed in the two gas pipes 401. The two gas pipes 401 are used symmetrically. First, the main control valve 402 is opened, and then the first one-way valve 404 and the second one-way valve 405 are opened alternately. When the first one-way valve 404 is opened, the first flow pipe 407 will extract the gas at one end of the first exhaust port 702, thereby moving the sealing piston 704 toward the second one-way valve 405. One end of the first exhaust port 702 moves. Since the push rod 703, the reinforcing rod 708, the fixing block 705, the connecting frame 709 and the cleaning ring 710 are all connected, the push rod 703 fixed by the sealing piston 704 will move the entire cleaning assembly 7 toward the end close to the first exhaust port 702. Conversely, the first one-way valve 404 is closed and the second one-way valve 405 is opened. The second flow pipe 406 will extract the gas at one end of the second exhaust port 707, thereby moving the sealing piston 704 toward the end close to the second exhaust port 707. The push rod 703 will move the entire cleaning assembly 7 toward the end near the second exhaust port 707, wherein the main valve 109, the fan 112, the servo motor 204, the master control valve 402, the first one-way valve 404 and the second one-way valve 405 are all electrically connected to the external control system and are controlled to start and stop by the external control system. Therefore, by controlling the first one-way valve 404 and the second one-way valve 405 to open alternately, the cleaning ring 710 can be reciprocated outside the heat exchange tube 106, and the heat exchange is cleaned by the cleaning brush 711 installed on the inner wall of the cleaning ring 710. The tube 106 is cleaned in time to prevent the accumulation of putty on the surface of the heat exchange tube 106 which is difficult to clean. After the cleaning is completed, all the first one-way valves 404 and all the second one-way valves 405 can be closed, and the two main control valves 402 can also be closed at the same time. It has two control modes and is more flexible to use. The cleaning brush 711 is made of silicone material with good heat dissipation performance. While completing the cleaning, it can assist in the dissipation of heat transferred from the heat exchange tube 106. When the heat exchange tube 106 needs to be flushed with a water gun at low pressure, the stains on the surface of the cleaning brush 711 can also be easily removed.

[0025] Example 2: Figures 1-9As shown, the air cooler assembly 1 includes a mounting frame 101, and a plurality of heat exchange tubes 106 for the flow of heat exchange medium are embedded between the opposite inner walls of the mounting frame 101, and a guide tube 105 is fixedly connected between one end of each two vertically adjacent heat exchange tubes 106, and each cleaning ring 710 is slidably sleeved on the outside of each heat exchange tube 106, and fixed side plates 103 are fixedly connected on both sides of the mounting frame 101, and the outer surfaces of the two fixed side plates 103 are provided with slide grooves 104 for the sliding of the fixed blocks 705, and a protective net 102 is fixedly embedded near both sides of the top of the mounting frame 101, and a connecting box 107 is fixedly installed at one end of the mounting frame 101, and an isolation plate 113 is fixedly connected between the inner walls of the connecting box 107, and the isolation plate 113 is used to divide the air holes of the plurality of heat exchange tubes 106 into two parts, an upper part and an lower part, and an outer surface of the connecting box 107 is fixedly connected to an air inlet pipe 108 near the top, and an outer surface of the connecting box 107 is fixed near the bottom. An air outlet pipe 110 is fixedly connected, and a main valve 109 is provided on the outer surface of the air outlet pipe 110. A fixed plate 111 is fixedly connected to the outer surface of the connecting box 107. A fan 112 is provided at the bottom of the fixed plate 111. The air delivery end of the fan 112 is fixedly connected to one end of the air outlet pipe 110. Two air supply components 2 are provided at the middle of the top of the mounting frame 101, each air supply component 2 includes a fan body 201, and a safety net 205 is fixedly connected to the bottom of each fan body 201. A mounting bucket 202 for guiding air is fixedly connected to the top of each fan body 201, and the mounting bucket 202 is wide at the top and narrow at the bottom. A mounting ring 203 is fixedly connected to the inner wall of each mounting bucket 202, and a servo motor 204 is provided on the top of each mounting ring 203. The output shaft of each servo motor 204 is fixedly connected to the rotating shaft of the two fan bodies 201 respectively, and the outer surfaces of the two fixed side plates 103 are fixedly connected to two support columns 5.

[0026] In this embodiment, when in use, by starting the fan 112, the fan 112 is caused to suck air, so that the gas to be cooled is sucked into the lower half of the connecting box 107 through the silencer pipe 301. However, each heat exchange tube 106 located in the lower half is connected to the lower half of the connecting box 107. Then, the gas to be cooled will pass through each heat exchange tube 106 located in the lower half, and then pass through each guide tube 105 into the multiple heat exchange tubes 106 located above, and finally pass through the air outlet pipe 110 and be discharged by the fan 112. At this time, the air cooler assembly 1 is working under the support of the four support columns 5. The servo motor 204 is installed on the mounting ring 203, so that the servo motor 204 can be connected to the outer casing of the fan body 201. By starting the servo motor 204, its output The shaft rotates, thereby driving the rotating shaft and fan blades inside the fan body 201 to rotate. The rotation direction is set to generate suction, so that the two fan bodies 201 can draw the air below them upward, and then take away the heat inside the heat exchange tube 106. When the air below flows upward, the inverted cone-shaped mounting bucket 202 can guide the airflow to the side, which can prevent the air from continuously blowing towards the servo motor 204, and has both an installation and a protection function for the servo motor 204. At this time, the air below will pass through the protective net 102 and the safety net 205 before being blown out. The function of the protective net 102 is to protect the heat exchange tube 106 inside the mounting frame 101, and the safety net 205 is to prevent the airflow from sucking debris into the fan blades of the fan body 201 and causing a short circuit, thereby improving safety.

[0027] Example 3: Figures 1-9 As shown, the air cooler assembly 1 includes a mounting frame 101, a connecting box 107 is fixedly installed at one end of the mounting frame 101, an isolation plate 113 is fixedly connected between the inner walls of the connecting box 107, the outer surface of the connecting box 107 is fixedly connected to an air inlet pipe 108 near the top, the top of the air inlet pipe 108 is fixedly connected to a noise reduction component 3 through a flange, the noise reduction component 3 includes a silencer 301, a plurality of silencers 302 for slowing down the propagation of sound waves are fixedly connected to the inner wall of the silencer 301, a sound-absorbing sleeve 303 for absorbing gas sound is pasted on the inner wall of the top end of the silencer 301, the outer surface of the silencer 301 is fixedly connected to a support frame 6, and the support frame 6 is fixedly mounted on the top of the connecting box 107.

[0028] In this embodiment, when in use, installing the silencer 301 at the air inlet pipe 108 will slow down the inhaled air flow rate to a certain extent. The multiple silencer buckets 302 inside the silencer 301 are bucket-shaped. After the external air enters the silencer 301 through the trumpet-shaped end of the silencer 301, the sound waves pass through each silencer bucket 302 in turn, thereby slowing down the air flow rate and attenuating the noise waves generated when the air is inhaled, thereby achieving the effect of reducing noise. The sound-absorbing sleeve 303 is made of sound-absorbing material and can absorb the sound generated when the air quickly enters the silencer 301, thereby enhancing the noise reduction effect. At the same time, installing the noise reduction component 3 at one end of the air inlet pipe 108 can avoid the air flow rate from being too fast, and can reduce the possibility of static electricity generated by the friction of air flow on the inner wall of the air inlet pipe 108, thereby effectively avoiding explosions caused by static electricity and improving safety. The silencer 301 is supported and fixed by the support frame 6.

[0029] The method of use and working principle of this device: When in use, when the heat exchange tube 106 completes its work, its surface needs to be cleaned in time. At this time, the main valve 109 is closed, so that the airflow generated by the operation of the fan 112 is dispersed in the two air pipes 401. The two air pipes 401 are used symmetrically. First, open the main control valve 402, and then alternately open the first one-way valve 404 and the second one-way valve 405. When the first one-way valve 404 is opened, the first flow pipe 407 will extract the gas at one end of the first exhaust port 702, thereby moving the sealing piston 704 toward the end close to the first exhaust port 702. Since the push rod 703, the reinforcing rod 708, the fixing block 705, the connecting frame 709 and the cleaning ring 710 are all relatively close, the air supply pipe 407 will be cleaned in time. If the first check valve 404 is connected, the push rod 703 fixed by the sealing piston 704 will move the entire cleaning component 7 toward the end close to the first exhaust port 702. Conversely, the first one-way valve 404 will be closed and the second one-way valve 405 will be opened, and the second flow pipe 406 will extract the gas at one end of the second exhaust port 707, thereby moving the sealing piston 704 toward the end close to the second exhaust port 707. Then the push rod 703 fixed by the sealing piston 704 will move the entire cleaning component 7 toward the end close to the second exhaust port 707. The main valve 109, the fan 112, the servo motor 204, the main control valve 402, the first one-way valve 404 and the second one-way valve 405 are all electrically connected to the external control system and are controlled by the external control system. The control is started and stopped, so by controlling the first one-way valve 404 and the second one-way valve 405 to open alternately, the cleaning ring 710 can be made to reciprocate outside the heat exchange tube 106, and the heat exchange tube 106 is cleaned in time by the cleaning brush 711 installed on the inner wall of the cleaning ring 710. After cleaning, all the first one-way valves 404 and all the second one-way valves 405 can be closed, and the two main control valves 402 can also be closed at the same time. It has two control modes, wherein the cleaning brush 711 is made of silicone material with good heat dissipation performance. While completing cleaning, it can assist in dissipating the heat transferred from the heat exchange tube 106. When the heat exchange tube 106 needs to be rinsed with a water gun at low pressure, it can also facilitate the removal of stains on the surface of the cleaning brush 711. During use, By starting the fan 112, the fan 112 is sucked, so that the gas to be cooled is sucked into the lower half of the connecting box 107 through the silencer pipe 301. However, each heat exchange tube 106 located in the lower half is connected to the lower half of the connecting box 107. Then, the gas to be cooled will pass through each heat exchange tube 106 located in the lower half, and then pass through each guide tube 105 into the multiple heat exchange tubes 106 located above, and finally pass through the air outlet pipe 110 and be discharged by the fan 112. At this time, the air cooler assembly 1 is working under the support of the four support columns 5. The servo motor 204 is installed on the mounting ring 203, so that the servo motor 204 can be connected to the casing of the fan body 201. By starting the servo motor 204,The output shaft rotates, thereby driving the rotating shaft and fan blades inside the fan body 201 to rotate. The rotation direction is set to generate suction, so that the two fan bodies 201 can draw the air below them upward, and then take away the heat inside the heat exchange tube 106. When the air below flows upward, the inverted cone-shaped installation bucket 202 can guide the airflow to the side, which can prevent the air from constantly blowing towards the servo motor 204. At this time, the air below will pass through the protective net 102 and the safety net 205 before being blown out. The function of the protective net 102 is to protect the heat exchange tube 106 inside the mounting frame 101, and the safety net 205 is to prevent the airflow from sucking debris into the fan blades of the fan body 201 and causing it to short-circuit. When in use, the silencer 30 1 is installed on the air inlet pipe 108, which will slow down the flow rate of the inhaled air to a certain extent. The multiple silencer hoppers 302 inside the silencer pipe 301 are hopper-shaped. After the external air enters the silencer pipe 301 through the trumpet-shaped end of the silencer pipe 301, the sound waves pass through each silencer hopper 302 in turn, thereby slowing down the air flow rate and attenuating the noise waves generated when the air is inhaled. The sound-absorbing sleeve 303 is made of sound-absorbing material and can absorb the sound generated when air quickly enters the silencer pipe 301. At the same time, installing the noise reduction component 3 at one end of the air inlet pipe 108 can prevent the air from flowing too fast and reduce the possibility of static electricity generated by air friction on the inner wall of the air inlet pipe 108. The silencer pipe 301 is supported and fixed by the support frame 6.
