Description

Technical Field

[0001] The invention relates to the technical field of cooling towers, and in particular to a cooling tower adsorption reflux device and an adsorption reflux method thereof. Background Art

[0002] The mainstream technology for flue gas water extraction is the condensation method. The circulating water cooling method supporting the condensation method generally adopts air cooling. Its cooling effect is very significantly affected by the ambient temperature, which causes the water extraction temperature to rise with the increase of the ambient temperature and to decrease with the decrease of the temperature. When the temperature is high in summer, the flue gas water extraction temperature can even reach 50°C, so it needs to be used in conjunction with a cooling tower. The cooling tower uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to reduce the water temperature. The cooling is to use water and air flow to exchange heat and generate steam. The steam evaporates and takes away the heat to achieve evaporative heat dissipation, convection heat transfer and radiation heat transfer. The principles are used to dissipate the waste heat generated in industry or refrigeration and air conditioning to reduce the water temperature. The evaporative heat dissipation device ensures the normal operation of the system. The device is generally barrel-shaped, so it is called a cooling tower.

[0003] When cooling water is cooled by existing cooling towers, the heated cooling water is usually sprayed on the filler to increase the heat dissipation by extending the residence time of the cooling water. However, during the peak period of heat exchange, it is difficult to quickly reduce the cooling water to an appropriate temperature by simply passing through the filler. When the cooling water is cooled by heat exchange, the hot air flow generated by the cooling water contains a large amount of moisture, which will be directly discharged through the fan. The steam water in the hot air flow cannot be collected and utilized, resulting in a huge waste of water resources. Summary of the invention

[0026] Preferably, a conical slow flow plate is fixedly connected to the top of the support column, and the conical slow flow plate is located above the spiral cooling plate. The surface of the conical slow flow plate is fixedly connected to a plurality of arc-shaped baffles evenly distributed on the surface of the conical slow flow plate.

[0027] Preferably, an adsorption reflux method for a cooling tower adsorption reflux device comprises the following steps: Step 1. Control the humidity of the external air entering the tower body for heat exchange through the air intake control mechanism. When the humidity in the external air is higher than the set value of the controller, the controller controls the arc-shaped electric shutters to close. The external humid air cannot directly enter the tower body through the arc-shaped air intake mesh and the arc-shaped electric shutters, and needs to enter the tower body through the space between the arc-shaped electric shutters and the metal condensation cylinder. After the humid air enters the space between the arc-shaped electric shutters and the metal condensation cylinder and contacts the surface of the metal condensation cylinder, the moisture in the air condenses after contacting the metal condensation cylinder with a lower temperature. The condensed water droplets finally slide down the surface of the metal condensation cylinder, thereby achieving dehumidification of the external humid air and controlling the humidity of the air entering the tower body for heat exchange.

[0028] Step 2: Use an external booster water pump to transport cooling water containing waste heat to the water distribution tray through the water inlet pipe, and use the nozzle on the water distribution tray to evenly spray the hot water above the packing layer. The external dry air entering through the bottom of the tower body cooperates to cool the hot water and exchange heat. At the same time, the driving motor drives the active pulley to rotate through the rotating shaft, and the active pulley drives the driven pulley to rotate through the synchronous belt. The rotation of the pulley drives the two exhaust blades to rotate through the driving shaft, so that the hot air flow rises and is discharged through the exhaust pipe.

[0029] Step 3: When the hot air flow rises, it first passes through the water filter trough, and the moisture in the hot air flow is initially adsorbed through the corners in the water filter trough, and slides to the top of the packing layer through its inclined surface. When the hot air flow rises, it is further filtered by the conical filter cover, and the moisture in the hot air flow is further adsorbed by the conical sponge cover, and the hot gas is discharged through the exhaust pipe. At the same time, the rotating shaft drives the driving gear to rotate, and the driving gear drives the rotating gear ring to rotate.

[0030] Step 4: Rotate the gear ring to drive the fixed sleeve and the telescopic rod to perform circular motion. The movement of the telescopic rod, through the cooperation of the pressure spring, enables its support to drive the pressure roller to fit the conical sponge cover for extrusion and rolling, so that the moisture adsorbed in the conical sponge cover is squeezed out and drips to the top of the packing layer, and flows along the conical filter cover to the annular guide groove, and flows into the top of the packing layer through the drainage hole, thereby achieving economical recycling.

[0031] Step 5. After the hot water in the packing layer is cooled by heat exchange with the air, it drips into the conical slow-flow plate. Through the cooperation of multiple arc-shaped baffles, the cooling water slowly flows down, thereby increasing the heat exchange time in contact with the air. After passing through the conical slow-flow plate, the cooling water enters the spiral cooling plate. Through the long distance of the spiral cooling plate, it further contacts with the air for heat exchange, and finally flows into the water collection tank and is pumped out through the circulating outlet pipe for recycling.

[0032] The beneficial effects of the present invention are: 1. By setting up a heat exchange mechanism, heat exchange is achieved for cooling water containing waste heat, and the evaporated hot air flow is filtered multiple times to adsorb and collect the moisture in the hot air flow, thereby solving the problem that the existing cooling tower only prolongs the residence time of cooling water through fillers, it is difficult to reduce the cooling water to a suitable temperature during the peak heat exchange period, and the moisture contained in the hot air flow is directly discharged by the fan, resulting in a waste of water resources.

[0033] 2. By setting up an air intake control mechanism, when in use, by controlling the humidity of the air participating in the heat exchange entering the tower body, the air participating in the heat exchange can be kept dry, achieving a better heat exchange cooling effect.

[0034] 3. By setting up a diversion cooling mechanism, the flow time of cooling water can be extended in a smaller space, thereby increasing the time for heat exchange between cooling water and air, thereby improving the cooling effect of cooling water. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Six arc-shaped air inlet mesh plates 503 distributed in a circular array with the axis of the tower body 2 as the center are fixedly connected to the surface of the fixed support frame 1.

[0042] Furthermore, when in use, the arc-shaped air inlet mesh plate 503 not only facilitates external air to enter the tower body 2 for heat exchange, but also protects the water collection tank 3 and the tower body 2 to prevent external debris from falling into the water collection tank 3 and the tower body 2.

The arc-shaped electric shutters 504 are electrically connected to the controller 501 through cables, and one end of the arc-shaped electric shutters 504 extends to the surface of the water collection pool 3.

[0044] When in use, the humidity of the air outside the tower body 2 is detected through the humidity sensor 502. When the humidity of the external air is lower than the set value, the controller 501 controls the arc-shaped electric shutters 504 to open, so that the external air can directly enter the tower body 2 through the arc-shaped air inlet mesh plate 503 and the arc-shaped electric shutters 504 for heat exchange. When the humidity of the external air is higher than the set value, the controller 501 automatically controls the arc-shaped electric shutters 504 to close to prevent the air with higher humidity from directly entering the tower body 2 and affecting the heat exchange effect on the cooling water.

[0048] Furthermore, by making the surface of the metal condensation cylinder 507 into an inverted eight-shaped shape, the contact area with the external air is increased, thereby achieving a better effect of dehumidifying and condensing the external air.

[0049] During use, when the humidity in the external air is higher than the set value of the controller 501, the controller 501 controls the arc-shaped electric shutter 504 to close, and the external humid air cannot directly enter the tower body 2 through the arc-shaped air inlet mesh plate 503 and the arc-shaped electric shutter 504, and needs to enter the tower body 2 through the space between the arc-shaped electric shutter 504 and the metal condensation cylinder 507.

Example

[0072] Reference Figure 1-Figure 10 , an adsorption reflux method for a cooling tower adsorption reflux device, the adsorption reflux method comprising the following steps: Step 1, control the humidity of the external air entering the tower body 2 for heat exchange through the air intake control mechanism. When the humidity in the external air is higher than the set value of the controller 501, the controller 501 controls the arc-shaped electric shutter 504 to close. The external humid air cannot directly enter the tower body 2 through the arc-shaped air intake mesh plate 503 and the arc-shaped electric shutter 504, and needs to enter the tower body 2 through the space between the arc-shaped electric shutter 504 and the metal condensation cylinder 507. After the humid air enters the space between the arc-shaped electric shutter 504 and the metal condensation cylinder 507 and contacts the surface of the metal condensation cylinder 507, the moisture in the air condenses after contacting the metal condensation cylinder 507 with a lower temperature. The condensed water droplets finally slide down the surface of the metal condensation cylinder 507, thereby achieving dehumidification of the external humid air and controlling the humidity of the air entering the tower body 2 for heat exchange. Step 2: The cooling water containing waste heat is transported to the water distribution tray 601 through the water inlet pipe 6 by an external booster water pump, and the hot water is evenly sprayed on the packing layer 602 by the nozzle on the water distribution tray 601. The external dry air entering from the bottom of the tower body 2 is used to cool down the hot water for heat exchange. At the same time, the driving motor 617 works, and the driving motor 617 drives the active pulley 619 to rotate through the rotating shaft 618. The active pulley 619 drives the driven pulley 625 to rotate through the synchronous belt, so that the rotation of the pulley drives the two exhaust blades 626 to rotate through the driving shaft 624, so that the hot air flow rises and is discharged through the exhaust pipe 622; Step 3: When the hot air flow rises, it first passes through the water filter tank 604, and the water in the hot air flow is initially adsorbed through the corners in the water filter tank 604, and slides down to the top of the packing layer 602 through its inclined surface. When the hot air flow rises, it is further filtered by the cone filter cover 607, and the water in the hot air flow is further adsorbed by the cone sponge cover 608, and then the hot gas is discharged through the exhaust pipe 622. At the same time, the rotating shaft 618 drives the driving gear 620 to rotate, and the driving gear 620 drives the rotating gear ring 611 to rotate; Step 4: Rotate the gear ring 611 to drive the fixed sleeve 612 and the telescopic rod 613 to perform circular motion. The movement of the telescopic rod 613, through the cooperation of the pressure spring 614, causes its support 615 to drive the pressure roller 616 to fit the conical sponge cover 608 for extrusion and rolling, so that the water adsorbed in the conical sponge cover 608 is squeezed out and drips onto the top of the packing layer 602, flows along the conical filter cover 607 into the annular guide groove 605, and flows into the top of the packing layer 602 through the drainage hole 606, thereby realizing economical recycling; Step 5. After the hot water in the packing layer 602 is cooled by heat exchange with the air, it drips into the conical slow-flow plate 703. The cooling water slowly flows down through the cooperation of multiple arc-shaped baffles 704, thereby increasing the heat exchange time with the air. After passing through the conical slow-flow plate 703, the cooling water enters the spiral cooling plate 702. Through the long distance of the spiral cooling plate 702, it further contacts with the air for heat exchange, and finally flows into the water collecting tank 3, and is pumped out through the circulating outlet pipe 4 for recycling.

10. An adsorption reflux method for a cooling tower adsorption reflux device according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Control the humidity of the external air entering the tower body (2) for heat exchange by means of an air intake control mechanism. When the humidity of the external air is higher than the set value of the controller (501), the controller (501) controls the arc-shaped electric shutter (504) to close. The external humid air cannot directly enter the tower body (2) through the arc-shaped air intake mesh plate (503) and the arc-shaped electric shutter (504). The external humid air needs to enter the tower body (2) through the space between the arc-shaped electric shutter (504) and the metal condensation cylinder (507). After the humid air enters the space between the arc-shaped electric shutter (504) and the metal condensation cylinder (507) and contacts the surface of the metal condensation cylinder (507), the moisture in the air contacts the metal condensation cylinder (507) with a lower temperature and condenses. The condensed water droplets finally slide down the surface of the metal condensation cylinder (507), thereby achieving dehumidification of the external humid air and controlling the humidity of the air entering the tower body (2) for heat exchange. Step 2: The cooling water containing waste heat is transported to the water distribution tray (601) through the water inlet pipe (6) by an external booster water pump, and the hot water is evenly sprayed on the top of the packing layer (602) through the nozzle on the water distribution tray (601). The hot water is cooled and heat-exchanged by the external dry air entering through the bottom of the tower body (2). At the same time, the driving motor (617) works, and the driving motor (617) drives the driving pulley (619) to rotate through the rotating shaft (618). The driving pulley (619) drives the driven pulley (625) to rotate through the synchronous belt, so that the rotation of the pulley drives the two exhaust blades (626) to rotate through the driving shaft (624), so that the hot air flow rises and is discharged through the exhaust pipe (622); Step 3: When the hot air flow rises, it first passes through the water filter trough (604), and the water in the hot air flow is initially adsorbed through the corners in the water filter trough (604), and slides down to the top of the packing layer (602) through its inclined surface. When the hot air flow rises, the hot air flow is further filtered by the cone filter cover (607), and the water in the hot air flow is further adsorbed by the cone sponge cover (608), and then the hot gas is discharged through the exhaust pipe (622). At the same time, the rotating shaft (618) drives the driving gear (620) to rotate, and the driving gear (620) drives the rotating gear ring (611) to rotate; Step 4: rotating the gear ring (611) to drive the fixed sleeve (612) and the telescopic rod (613) to perform circular motion; the movement of the telescopic rod (613) enables the support (615) to drive the pressure roller (616) to fit the conical sponge cover (608) for extrusion and rolling through the pressure spring (614), so that the water adsorbed in the conical sponge cover (608) is squeezed out and drips onto the top of the packing layer (602), flows along the conical filter cover (607) into the annular guide groove (605), and flows into the top of the packing layer (602) through the drainage hole (606); Step 5: After the hot water in the packing layer (602) is cooled by heat exchange with the air, it drips into the conical slow-flow plate (703). The cooling water is slowly flowed down by the cooperation of a plurality of arc-shaped retaining bars (704), thereby increasing the heat exchange time in contact with the air. After passing through the conical slow-flow plate (703), the cooling water enters the spiral cooling plate (702). Through the long distance of the spiral cooling plate (702), the cooling water further contacts with the air for heat exchange, and finally flows into the water collection tank (3), and is pumped out through the circulating outlet pipe (4) for recycling.
