Description

Technical Field

[0001] The invention relates to the technical field of countercurrent cooling towers, in particular to a countercurrent cooling tower with balanced cooling and a cooling control method thereof. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the heat exchange between water and air flow to generate steam. The steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer. It dissipates the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature through evaporative heat dissipation to ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower.

[0003] When using existing cooling towers, the hot water that needs to be cooled often contains more impurities, and most cooling towers do not have the function of preventing the nozzles from being blocked. As a result, after a period of use, the cooling towers are prone to the phenomenon of impurities blocking the nozzles, thereby affecting the spraying effect of the nozzles. At the same time, during the cooling process, some water vapor is often discharged from the fan to the outside along with the hot air, which will cause the loss of some water sources and the waste of water resources, further reducing the practicality of the cooling tower.

[0008] Preferably, two groups of dustproof nets are provided on the outer surface of the tower body, and the interior of each of the dustproof nets is threadedly connected with two groups of fixing bolts, and one end of each fixing bolt close to the tower body passes through the dustproof net and extends to the interior of the tower body.

[0009] The installation of the dust screen can prevent dust from entering the interior of the tower as much as possible, and the installation of the fixing bolts can facilitate workers to dismantle and clean the dust screen.

[0010] Preferably, a ladder is fixedly mounted on the left side of the tower body, and anti-slip sleeves arranged at equal distances are fixedly mounted on the outer surface of the ladder.

[0011] The installation of the ladder makes it convenient for workers to climb to a high place to maintain the device, and the installation of the anti-slip cover increases the safety of workers' climbing.

[0017] The installation of the support table plays a role in stabilizing the rotating motor.

[0021] The installation of the slide plate and the slide rail serves to limit the moving trajectory of the scraper.

[0022] Preferably, the countercurrent cooling tower temperature control method for balanced temperature reduction is as follows: S1. During use, workers connect the hot water supply pipe with the connecting pipe. After that, the hot water is filtered through the filter and enters the inside of the delivery pipe. Then, it is sprayed on the inside of the tower through the nozzle. Then, workers turn on the fan and use the power provided by the fan to extract the gas inside the tower into the inside of the air outlet pipe. At the same time, when the hot water comes out of the nozzle, the hot water is sprayed on the filler. After that, the hot water flows to the bottom of the tower after passing through the filler. At the same time, the outside air passes through the dustproof net and enters the inside of the tower. Then, the gas flows upward to cool the hot water. When the inlet water temperature T1 = 37-40℃, the outlet water temperature T2 = 32℃, the wet bulb temperature WBT = 28℃, and the water temperature drops TS = 5-8℃ When the water inlet temperature T1 = 43-60℃, the water outlet temperature T2 = 33-35℃, the wet bulb temperature WBT = 28℃, and the water temperature drop TS = 10-25℃. When the water spraying efficiency of the nozzle decreases, the worker closes the two solenoid valves in the front and rear directions and opens the solenoid valve at the bottom. Then the worker connects the water pump to the water source pipeline, uses the water pump to transport water to the inside of the treatment box, and uses the power provided by the rotating motor to drive the turntable to rotate, so that the turntable drives the connecting rod to rotate, and then the connecting rod drives the toothed disc to rotate periodically at a certain angle. At the same time, the toothed disc drives the toothed rod to move left and right under the restriction of the limit seat, so as to brush the filter screen; S2. When the hot and humid air enters the air outlet duct, the gas contacts the condensation plate, so that the hot and humid air condenses on the condensation plate under the action of cold condensation. At the same time, the power provided by the rotating motor is used to drive the connecting plate to rotate, so that the connecting plate drives the connecting column to rotate, and then the connecting column drives the moving frame to move up and down periodically under the restriction of the limit block, so that the moving frame drives the fixed sleeve and the scraper to move up and down, so that the scraper scrapes the water droplets on the condensation plate away from the condensation plate, thereby facilitating the subsequent condensation process of the air; S3. When the condensed water enters the collection box, the float will move upward with the height of the condensed water level under the action of buoyancy, thereby monitoring the height of the condensed water level in real time. When the float contacts the pressure sensor, the pressure sensor transmits a signal to the controller, which controls the buzzer to sound and the warning light to light up, thereby warning the workers and allowing them to open the drain pipe to discharge the condensed water inside the drain pipe.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are: First, the present invention is provided with a processing box, a connecting pipe, a solenoid valve, a filter, a delivery pipe and a nozzle, and uses the filter to filter the hot water that needs to be cooled, so as to avoid as much as possible that the hot water contains a lot of impurities that clog the nozzle. By providing a rotating motor, a turntable, a connecting rod, a toothed disc, a toothed rod, a cleaning rack and a water pump, the front and rear connecting pipes are closed by the solenoid valve, and the lower connecting pipe is opened at the same time. Then, the power provided by the water pump is used to fill the interior of the processing box with a source of water for cleaning, and the power provided by the rotating motor is used to cooperate with the turntable, the connecting rod and the toothed disc to drive the toothed rod and the cleaning rack to move periodically, so as to clean the filter, avoid the accumulation of a lot of impurities that affect the circulation of hot water that needs to be cooled, and thereby increase the practicality of the device.

[0024] Second, the present invention is provided with an air outlet duct, a condensation plate, a semiconductor refrigeration sheet and a condensation tube, and utilizes the effect of pre-condensation of hot air to make the moisture in the hot air blown out of the tower body condense on the condensation plate, thereby reducing the loss of water sources and the loss of water resources. By providing a rotating motor, a connecting plate, a connecting column, a movable frame, a fixed sleeve and a scraper, the power provided by the rotating motor is used in conjunction with the connecting plate and the connecting column to drive the movable frame, the fixed sleeve and the scraper to move periodically, thereby scraping off the condensed water droplets on the condensation plate, thereby facilitating the subsequent condensation of water vapor, and further increasing the practicality of the device.

[0025] Third, the present invention achieves the purpose of collecting condensed water by providing a collection box. By providing a float, a pressure sensor, a controller, a buzzer, a warning light, a drain pipe and a slide rod, the buoyancy of the float in the water is utilized to make the float move with the height of the water surface. When the float contacts the pressure sensor, the controller controls the buzzer and the warning light to issue an alarm, thereby reminding the workers to discharge the condensed water inside the collection box, thereby facilitating the collection of subsequent condensed water.

At the same time, the power provided by the rotating motor 305 is used to drive the connecting plate 306 to rotate, so that the connecting plate 306 drives the connecting column 307 to rotate, and then the connecting column 307 drives the moving frame 308 to move up and down periodically under the restriction of the limit block 17, so that the moving frame 308 drives the fixed sleeve 309 and the scraper 310 to move up and down, so that the scraper 310 scrapes the water droplets on the condensation plate 302 away from the condensation plate 302, thereby facilitating the subsequent condensation process of the air; S3. After the condensed water enters the collection box 401, under the action of buoyancy, the float 402 will move upward with the height of the condensed water level, thereby monitoring the liquid level of the condensed water in real time. When the float 402 contacts the pressure sensor 403, the pressure sensor 403 transmits a signal to the controller 404, so that the controller 404 controls the buzzer 405 to make a sound and controls the warning light 406 to light up, thereby warning the workers and allowing them to open the drain pipe 407 to discharge the condensed water inside the drain pipe 407.

[0044] The working principle of the present invention is as follows: when in use, a worker fixes the hot water supply pipeline and the connecting pipe 202 in communication, and then the hot water enters the interior of the delivery pipe 211 after being filtered by the filter screen 204, and then is sprayed on the interior of the tower body 1 through the nozzle 212, so as to avoid as much as possible that the hot water contains a lot of impurities that clog the nozzle 212, thereby ensuring the smoothness of the nozzle 212, and then the worker turns on the fan 5, and uses the power provided by the fan 5 to extract the gas inside the tower body 1 into the interior of the air outlet pipe 301, and at the same time, when the hot water flows from the nozzle 212, the hot water is sprayed on the filler 6, and then the hot water flows through the filler 6 to the bottom of the tower body 1, and at the same time, the outside air enters the interior of the tower body 1 after passing through the dustproof net 9, and then the gas flows upward, thereby The hot water is cooled and cooled. When the water spraying efficiency of the nozzle 212 is reduced, the worker closes the two solenoid valves 203 in the front and rear directions and opens the solenoid valve 203 at the bottom. Then the worker connects the water pump 213 with the water source pipeline, and uses the water pump 213 to transport water to the inside of the treatment box 201. At the same time, the power provided by the rotating motor 205 is used to drive the turntable 206 to rotate, so that the turntable 206 drives the connecting rod 207 to rotate, and then the connecting rod 207 drives the toothed disc 208 to rotate periodically at a certain angle. At the same time, the toothed disc 208 drives the toothed rod 209 to move left and right under the restriction of the limit seat 13, so as to brush the filter 204 and prevent impurities from accumulating in the filter. The filter screen 204 ensures a good water spraying effect of the nozzle 212. When the hot and humid air enters the air outlet pipe 301, the gas contacts the condensation plate 302, so that the hot and humid air condenses on the condensation plate 302 under the effect of cold condensation, thereby condensing and collecting the moisture brought out during the cooling process, thereby reducing the loss of moisture. At the same time, the power provided by the rotating motor 305 is used to drive the connecting disk 306 to rotate, so that the connecting disk 306 drives the connecting column 307 to rotate, and then the connecting column 307 drives the moving frame 308 to move up and down periodically under the restriction of the limit block 17, so that the moving frame 308 drives the fixed sleeve 309 and the scraper 310 to move up and down, so that the scraper 310 will The water droplets on the condensation plate 302 are scraped off the condensation plate 302, thereby facilitating the subsequent condensation processing of the air. When the condensed water enters the interior of the collection box 401, under the action of buoyancy, the float 402 will move upward with the height of the condensed water liquid level, thereby monitoring the liquid level of the condensed water in real time. When the float 402 contacts the pressure sensor 403, the pressure sensor 403 transmits a signal to the controller 404, so that the controller 404 controls the buzzer 405 to make a sound, and at the same time controls the warning light 406 to light up, thereby warning the workers and allowing the workers to open the drain pipe 407 to discharge the condensed water inside the drain pipe 407, thereby facilitating the subsequent collection of condensed water and further reducing water loss.
