Description

Technical Field

[0001] The invention relates to a demisting cooling tower, in particular to a demisting cooling tower which cools down by circulating spray water. Background Art

[0002] A cooling tower is an evaporative heat dissipation device that uses the principles of evaporative heat dissipation, convection heat transfer, and radiation heat transfer to dissipate waste heat generated in industry or refrigeration and air conditioning to reduce the water temperature to ensure the normal operation of the system. However, a large amount of smoke will be generated during the operation of the cooling tower, which will affect the surrounding environment. Therefore, a cooling tower that can eliminate mist is needed.

[0003] The patent with the patent authorization announcement number CN212585526U discloses a demisting cooling tower that enhances heat and mass transfer by spraying water. The demisting cooling tower includes a demisting cooling tower body, the top of which is rotatably connected with a rotating pipe, and the top is fixedly connected with a motor and an L-shaped plate, the outer wall of the rotating pipe located outside the demisting cooling tower body is fixedly sleeved with a driven gear, and one end located inside the demisting cooling tower body is connected to a water receiving tray, the outer wall of the water receiving tray is connected to a horizontally arranged spray pipe in a circular array, the base surface of the L-shaped plate is fixedly connected with a water supply pipe joint, the top of the motor is the output end, and the shaft is connected to a driving gear. When the demisting cooling tower is in use, the top port of the water supply pipe joint is connected to a water pump to supply water to the inside of the rotating pipe, and then the water enters the water receiving tray and is diverted to each spray pipe, and then the water is sprayed out from the spray port. The motor drives the driven gear to rotate through the driving gear, and the rotating pipe rotates on the demisting cooling tower body.

[0041] See also Figure 4-Figure 6 The spray mechanism 7 includes a first fixed seat 701, a first water storage tank 702, a first non-return valve 703, a first fixed block 704, a water pipe 705 and a nozzle 706. The first fixed seat 701 is fixedly arranged on the upper right part of the support frame 1, and the left side of the first fixed seat 701 is connected to the second shell 4. The first water storage tank 702 is fixedly arranged on the first fixed seat 701. The first water storage tank 702 can store cold water. The first non-return valve 703 is fixedly connected to the upper right part of the first water storage tank 702. The first fixed block 704 is symmetrically welded in the front and back of the upper part of the second shell 4. The top and left side of the first water storage tank 702 are fixedly connected with water pipes 705. The front and rear ends of the upper water pipe 705 both penetrate the upper part of the second shell 4 and are connected to the first fixed block 704. The front and rear ends of the two water pipes 705 are fixedly arranged with nozzles 706. The upper nozzle 706 is located in the second shell 4, and the front and rear two nozzles 706 of the lower are embedded in the middle of the second shell 4.

[0042] See also Figure 7-Figure 9 The mist dissipation mechanism 8 includes a second fixed seat 801, a first rotating shaft 802, an exhaust fan 803, a servo motor 804, a second water storage tank 805, a second one-way valve 806, a first water outlet pipe 807 and a ball valve 808. The second fixed seat 801 is welded on the top of the second housing 4. The first rotating shaft 802 is rotatably arranged in the middle of the second fixed seat 801. The exhaust fan 803 is fixedly arranged at the lower part of the first rotating shaft 802. The exhaust fan 803 can draw the mist upward. A servo motor 804 is fixedly arranged at the middle position of the top, and the output shaft of the servo motor 804 is connected to the top of the first rotating shaft 802 through a coupling. A second water storage tank 805 is fixedly arranged in the upper part of the second fixed seat 801, and the second water storage tank 805 can condense the mist into water droplets.

A ball valve 808 is rotatably arranged on the first water outlet pipe 807.

[0043] When it is necessary to use the device, the staff connects the external hot water pipe to the water supply pipe 5, and the hot water then enters the water supply pipe 5. At this time, the staff connects the external water pipe to the first one-way valve 703, and the cold water then enters the first water storage tank 702 through the first one-way valve 703. The water in the first water storage tank 702 is then sprayed out from the nozzle 706 to the water supply pipe 5 through the water supply pipe 705, thereby achieving the cooling of the hot water. At the same time, the cold air from the outside enters the second shell 4 through the first filter 3 to cool the water supply pipe 5. Under the action of the first filter 3, larger impurities in the air can be filtered out. Since the surface of the water supply pipe 5 is relatively hot, mist will be generated when it encounters cold water. Subsequently, the staff connects another external water pipe to the second one-way valve 806, and the cold water then passes through the second one-way valve 806 into the second water storage tank 805. After the cold water in the second water storage tank 805 reaches a certain amount, the staff removes the external water pipe. After removal, the staff starts the servo motor 804. The output shaft of the servo motor 804 rotates to drive the first rotating shaft 802 to rotate. The rotation of the first rotating shaft 802 drives the exhaust fan 803 to rotate. The exhaust fan 803 rotates to draw the mist upward and connect it to the bottom of the second water storage tank 805. Since cold water is stored in the second water storage tank 805, when the mist contacts the bottom of the second water storage tank 805, the mist will condense into water droplets, which will fall along the second fixing seat 801 and the inner wall of the second shell 4 to the water collecting bucket 6, and the water collected in the water collecting bucket 6 will then flow out through the first shell 2. At this time, the staff will place a container at the bottom of the first shell 2 to collect the condensed water, thereby achieving the purpose of centrally collecting the water generated in the mist elimination process. When the water in the second water storage tank 805 needs to be replaced, the staff will turn the ball valve 808 to open the first water outlet pipe 807, and the second The water in the water tank 805 is then discharged through the first water outlet pipe 807. After the release is completed, the staff reverses the ball valve 808 to close the first water outlet pipe 807, and then the staff again connects the external water pipe to the second one-way valve 806 to allow cold water to enter the second water tank 805 again. After the cold water in the second water tank 805 reaches a certain amount, the staff again removes the external water pipe. After the use of this device is completed, the staff removes the external water pipe on the first one-way valve 703. After removal, the nozzle 706 no longer sprays cold water, and then the staff turns off the servo motor 804 to stop operation.

[0044] Example 2

[0045] See also Figure 1 , Fig.10 and Fig.11, on the basis of Embodiment 1, it further includes a blanking mechanism 9. The blanking mechanism 9 can make the lower nozzle 706 spray water intermittently. The blanking mechanism 9 includes a guide rod 901, a second baffle 902, a first elastic member 903, a mounting plate 904, a second fixing block 905, a top plate 906, and a cam 907. The guide rod 901 is welded to the left side of the top of the first water storage tank 702. The second baffle 902 is slidably arranged on the guide rod 901. The second baffle 902 penetrates the first water storage tank 702 to block the lower water delivery pipe 705. A first elastic member 903 is connected between the top of the second baffle 902 and the upper part of the guide rod 901. The first elastic member 903 is sleeved on the guide rod 901. Mounting plates 904 are symmetrically and fixedly arranged on the front and rear of the second baffle 902. Second fixing blocks 905 are symmetrically welded to the front and rear of the top of the second fixing seat 801. A top plate 906 is slidably arranged between the two second fixing blocks 905. When the top plate 906 slides to the left, it will contact the mounting plate 904. The upper part of the first rotating shaft 802 is key-connected with a cam 907. When the cam 907 rotates, it will contact the top plate 906.

[0046] The rotation of the first rotating shaft 802 drives the rotation of the cam 907. When the cam 907 rotates, it squeezes the top plate 906 to slide to the left on the second fixing block 905. The leftward sliding of the second fixing block 905 drives the mounting plate 904 to move upward. The upward movement of the mounting plate 904 drives the second baffle 902 to slide upward. The first elastic member 903 is compressed accordingly. The upward sliding of the second baffle 902 no longer blocks the lower water delivery pipe 705. The cold water in the first water storage tank 702 then sprays out from the lower nozzle 706 through the lower water delivery pipe 705 to cool the water delivery pipe 5. When the cam 907 stops squeezing the top plate 906 during rotation, the first elastic member 903 resets and drives the second baffle 902 to slide downward and reset to block the lower water delivery pipe 705 again. The lower nozzle 706 no longer sprays cold water. The downward sliding of the second baffle 902 drives the mounting plate 904 to move downward and reset. The downward movement of the mounting plate 904 squeezes the top plate 906 to slide to the right and reset on the second fixing block 905. By continuously rotating the cam 907, the top plate 906 can be made to slide left and right continuously, causing the second baffle 902 to slide up and down continuously, thus achieving the purpose of intermittent spraying of the lower nozzle 706, which is beneficial for cooling the water delivery pipe 5.

When the second filter screen 1107 needs to be replaced, the staff pulls the limit block 1108 to drive the first slide bar 1102 to slide backward, and the second elastic member 1104 is compressed backward accordingly. The first slide bar 1102 slides backward and drives the block 1103 to move backward and no longer jams the filter box 1105.
