Description

Technical Field

[0001] The invention belongs to the technical field of filtration and separation, and particularly relates to a cooling tower using a bamboo lattice filler energy-saving and environmentally friendly device. Background Art

[0002] As a key heat dissipation device in industrial production and refrigeration and air-conditioning systems, cooling towers' core function is to cool circulating water through heat exchange between water and air. Using water as the circulating coolant, these devices utilize the triple action of evaporative heat dissipation, convection heat transfer, and radiation heat transfer to dissipate excess heat absorbed by the system into the atmosphere through vaporization. A typical cooling tower utilizes a barrel-shaped structure. During operation, heat exchange occurs through contact between a water curtain and air flow, thereby continuously maintaining the operating temperature of the circulating water system and ensuring normal operation of the equipment. With the acceleration of industrialization, its application has expanded to numerous key sectors, including power, chemical, and data centers.

[0003] However, cooling towers face serious contamination issues due to their long-term exposure to the open air and the constant contact between the spray trough and the outside world. Airborne pollutants such as suspended particulate matter, microorganisms, and dust continuously infiltrate the water circulation system. Furthermore, minerals carried by the water itself combine with corrosion products from the equipment to form complex deposits. These impurities accumulate within the cooling tower, causing physical obstructions such as clogging of the packing layer and uneven spraying, while also significantly reducing heat transfer efficiency. Summary of the Invention

[0004] The present invention provides a cooling tower using an energy-saving and environmentally friendly bamboo lattice filler device, aiming to solve the technical problem that impurities continuously accumulate inside the cooling tower, causing physical obstacles such as clogging of the filler layer and uneven spraying, and significantly reducing the heat conduction efficiency.

[0005] To achieve the above-mentioned object, the technical solution adopted by the present invention is as follows: providing a cooling tower using a bamboo lattice filler energy-saving and environmentally friendly device, comprising a tower body, wherein a water distribution system, a filler layer, a filtration system, and a recovery system are sequentially arranged inside the tower body from top to bottom, wherein the water distribution system is used to evenly spray water onto the filler layer, and the recovery system is used to receive water and pump the water into the water distribution system;

[0018] a push plate fixedly connected to the telescopic end of the telescopic member;

[0019] a reciprocating unit connected to the telescopic member and configured to drive the telescopic member to reciprocate along the axis of the cylinder;

[0020] When the telescopic member moves toward the direction approaching the debris outlet, the telescopic member extends so that the bottom end of the push plate abuts against the inner bottom wall of the cylinder; when the telescopic member moves away from the debris outlet, the telescopic member retracts so that the push plate separates from the inner bottom wall of the cylinder.

[0021] In one possible implementation, a partition is fixedly connected to the cylinder, the surface of the partition is parallel to the axis of the cylinder, and the partition divides the internal space of the cylinder into a debris removal chamber connected to the debris inlet and a power chamber connected to the debris removal chamber. The telescopic member is slidably mounted on the bottom wall of the partition, and the reciprocating unit is disposed in the power chamber.

[0022] When the telescopic member is extended, the bottom end of the push plate is separated from the bottom wall of the partition; when the telescopic member is retracted, the top end of the push plate abuts against the bottom wall of the partition.

[0047] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0048] Please also refer to Figures 1 to 7, the present invention describes an energy-saving and environmentally friendly cooling device using bamboo lattice filler. A cooling tower using an energy-saving and environmentally friendly device with bamboo lattice fillers includes a tower body 10. A water distribution system 101, a filler layer 102, a filtration system 103, and a recovery system 104 are sequentially arranged in the tower body 10 from top to bottom. The water distribution system 101 is used to evenly spray water on the filler layer 102, and the recovery system 104 is used to receive water and pump the water into the water distribution system 101; the filtration system 103 includes a filtration unit 20, a debris removal barrel 30, and a power unit 40; the filtration unit 20 includes a sieve plate 201 horizontally arranged in the tower body 10 and a sieve box 202 connected to the bottom of the sieve plate 201, the center of the sieve plate 201 is provided with a notch 2011, and the opening of the sieve box 202 is connected to the notch 2011; the debris removal barrel 30 is connected to the top of the sieve plate 201 and is used to suck impurities on the upper surface of the sieve plate 201 into the sieve box 202; the power unit 40 is connected to the debris removal barrel 30 and is used to drive the debris removal barrel 30 to rotate with the axis of the sieve plate 201 as the rotation axis.

[0049] This embodiment provides a cooling tower using an energy-saving and environmentally friendly bamboo lattice packing device. Compared to the prior art, water passing through the packing layer 102 falls onto the surface of the sieve plate 201, and impurities in the water (such as algae and calcified particles) are trapped on the upper surface of the sieve plate 201. The purified water falls into the recovery system 104. The power unit 40 drives the impurity removal drum 30 to rotate around the axis of the sieve plate 201. During the rotation, the impurity removal drum 30 draws impurities on the upper surface of the sieve plate 201 into the screen box 202, facilitating centralized impurity processing. The present invention filters out impurities in the water and then concentrates them in the screen box 202 for processing, preventing impurities from accumulating within the cooling tower. This not only reduces physical obstacles such as clogging of the packing layer 102 and uneven spraying, but also improves heat conduction efficiency.

[0050] In some embodiments, see Figure 1 and Figure 7 The filler layer 102 is a bamboo lattice filler 1021 .

It is normal for the bamboo strips to have burrs and nodes on the surface and do not require treatment.

[0052] Requirements for 1021 Bamboo Filler: 1. The connecting rods for 1021 bamboo filler should be either "I"-shaped or "T"-shaped. These rods should be machined and then dried twice. The "I" or "T"-shaped rods should be 500mm ± 10mm long and 12mm ± 1mm ​​in diameter.

[0054] 3. The length of the bamboo lattice filler 1021 assembly block is 3000mm ± 100mm, and the width is 500mm ± 10mm. All bamboo pieces within 6 meters above the root cutting position are used as the tower core filler. Other parts of the bamboo are not allowed to be used to ensure the rigidity and strength of the bamboo lattice filler 1021.

[0055] 4. The assembly specifications of bamboo grid filler 1021 are: 3000×500 (mm), bamboo piece thickness is more than 6mm, bamboo piece spacing is 55mm±5㎜, each filler has 8 bamboo pieces, 4 pieces are assembled in the right direction and 4 pieces are assembled in the wrong direction, and the 8 pieces must not be assembled in the same direction.

[0056] 5. The assembly of bamboo grid filler 1021 must be completed with 4 I-axis or T-axis bamboo skewers, with the spacing between the pieces not exceeding 60mm to ensure that they are firmly fastened and cannot fall off during relocation and installation.

[0057] 6. The appearance of bamboo grid filler 1021 is not damaged, the spacing between bamboo boards is roughly uniform and no more than 60mm, the plastic sleeve is not damaged, and there are no cracks in the holes of bamboo strips.

[0058] Installation requirements for bamboo lattice filler 1021: 1. After the bamboo lattice filler 1021 is assembled, it should be manually transported to the height of the water layer via a transport platform for installation; 2. Install the bamboo lattice filler 1021 first, and then remove all transport platforms after installation; 3. The bamboo lattice filler 1021 should be placed at a 90-degree angle or a 45-degree angle, and the layers should be arranged in a grid shape vertically and horizontally; 4. After the bamboo lattice filler 1021 is installed, the filler forms a good integrity in the tower, creating good conditions for use and maintenance, with even water distribution and low ventilation resistance; 5. The gap between the filler in the tower body 10 and the tower wall should not be greater than 100m m. No gap greater than 100mm is allowed between the filling blocks and the interlayers in the tower; 6. The bamboo lattice filler 1021 should be installed smoothly to prevent damage to the components during installation; 7. The installation of the bamboo lattice filler 1021 must be tight and strict.

When installing the bamboo lattice filler 1021, clean up the debris at any time to prevent local blockage. During the construction and installation process, it is strictly forbidden to carry out welding operations above the filler. Fire prevention measures should be taken when necessary; 9. After the installation of the bamboo lattice filler 1021, ensure that the work is completed, the materials are clean, and the site is clean.

[0059] In some embodiments, see Figure 1 The power unit 40 includes a drive cylinder 401 and a drive member (not shown); the drive cylinder 401 is rotatably connected to the inner wall of the notch 2011; the drive member is transmission-connected to the drive cylinder 401 for driving the drive cylinder 401 to rotate about the axis of the sieve plate 201.

[0060] It should be noted that the driving member is a waterproof motor, which is connected to the driving cylinder 401 through a gear set. A water guide cover is provided above the driving member. The setting of the water guide cover prevents water from falling on the driving member, thereby extending the service life of the driving member.

[0061] The driving member starts to drive the driving cylinder 401 to rotate through the gear set, and the driving cylinder 401 drives the impurity removal cylinder 30 to rotate, so that the impurity removal cylinder 30 sucks all the impurities on the upper surface of the screen plate 201 into the screen box 202 to avoid leaving dead corners.

[0062] In some embodiments, see Figure 2 and Figure 3 The impurity removal cylinder 30 includes a cylinder body 301 and a suction piece 302; the axis of the cylinder body 301 is parallel to the radial direction of the sieve plate 201, one end of the cylinder body 301 extends into the driving cylinder 401 and the two are fixedly connected, the outer periphery of the cylinder body 301 is provided with an impurity inlet 3011, and the end of the cylinder body 301 extending into the driving cylinder 401 is provided with an impurity outlet 3012; the suction piece 302 is fixed to the cylinder body 301, the suction piece 302 has an inlet 3021 facing the upper surface of the sieve plate 201 and an outlet 3022 connected to the impurity inlet 3011, and the inlet 3021 extends along the radial direction of the sieve plate 201.

[0063] It should be noted that the suction member 302 may be a suction machine, which sucks impurities on the surface of the sieve plate 201 into the cylinder 301 through suction.

[0064] The driving cylinder 401 drives the impurity removal cylinder 30 to rotate during the rotation. The rotation of the impurity removal cylinder 30 causes the cylinder body 301 and the suction member 302 to rotate synchronously, thereby covering the entire surface of the screen plate 201 and avoiding leaving dead corners.

[0065] In some embodiments, see Figure 3 and Figure 4 A pushing unit 50 is provided in the cylinder 301, and the pushing unit 50 includes a telescopic member 501, a push plate 502 and a reciprocating unit; the telescopic member 501 is slidably connected to the cylinder 301, and the telescopic direction of the telescopic member 501 is perpendicular to the axis of the cylinder 301; the push plate 502 is fixed to the telescopic end of the telescopic member 501; the reciprocating unit is connected to the telescopic member 501, and is used to drive the telescopic member 501 to reciprocate along the axial direction of the cylinder 301.

[0066] When the telescopic member 501 moves toward the direction of the debris outlet 3012, the telescopic member 501 extends so that the bottom end of the push plate 502 abuts against the inner bottom wall of the cylinder 301; when the telescopic member 501 moves away from the debris outlet 3012, the telescopic member 501 retracts so that the push plate 502 separates from the inner bottom wall of the cylinder 301.

[0067] The reciprocating unit drives the telescopic member 501 to reciprocate within the cylinder 301, and the telescopic member 501 drives the push plate 502 to reciprocate within the cylinder 301. During the reciprocating movement of the telescopic member 501, when the telescopic member 501 moves toward the impurity outlet 3012, the telescopic member 501 extends, causing the push plate 502 to move downward until it aligns with the inner bottom wall of the cylinder 301, thereby allowing the push plate 502 to push all impurities attached to the inner bottom wall of the cylinder 301 into the impurity outlet 3012; when the telescopic member 501 moves away from the impurity outlet 3012, the telescopic member 501 retracts, causing the push plate 502 to move upward and separate from the inner bottom wall of the cylinder 301, thereby preventing the push plate 502 from bringing impurities back during the return process.

[0068] In some embodiments, see Figure 3 The cylinder 301 is fixedly connected to a partition 3013, the plate surface of the partition 3013 is parallel to the axis of the cylinder 301, and the partition 3013 divides the internal space of the cylinder 301 into a debris removal chamber 3014 connected to the debris inlet 3011 and a power chamber 3015 connected to the debris removal chamber 3014. The telescopic member 501 is slidably arranged on the bottom wall of the partition 3013, and the reciprocating unit is arranged in the power chamber 3015.

[0069] When the telescopic member 501 is extended, the bottom end of the push plate 502 is separated from the bottom wall of the partition 3013 ; when the telescopic member 501 is retracted, the top end of the push plate 502 abuts against the bottom wall of the partition 3013 .

[0070] When the telescopic member 501 moves in the direction away from the impurity outlet 3012, the telescopic member 501 retracts, causing the push plate 502 to move upward and separate from the inner bottom wall of the cylinder 301 until it abuts against the bottom wall of the partition 3013. During the return process, the push plate 502 will not bring back impurities and can also scrape off impurities attached to the bottom wall of the partition 3013, thereby avoiding the accumulation of impurities in the cylinder 301.

[0071] Impurities adhering to the reciprocating unit for a long time will damage the reciprocating unit and reduce the service life of the reciprocating unit; the cylinder 301 is divided into two chambers by the partition 3013. After the impurities are sucked into the cylinder 301, the impurities enter the impurity removal chamber 3014, reducing the possibility of impurities entering the power chamber 3015, avoiding impurities from adhering to the reciprocating unit, and ensuring the service life of the reciprocating unit.

[0072] In some embodiments, see Figures 3 to 5 The partition plate 3013 is provided with a guide groove 30131 extending along the axis of the cylinder 301, connecting the impurity removal chamber 3014 and the power chamber 3015. The guide groove 30131 extends along the axis of the cylinder 301. The reciprocating unit comprises a reciprocating shaft 503, a power member (not shown), and a transmission block 504. The reciprocating shaft 503 is rotatably connected to the inner wall of the impurity removal chamber 3014. Two spiral transmission grooves 5031 are defined on the outer circumference of the reciprocating shaft 503. The ends of the two transmission grooves 5031 are interconnected and mirror-symmetrically distributed along the axis of the reciprocating shaft 503. The power member is in transmission connection with the reciprocating shaft 503, and is used to drive the reciprocating shaft 503 to rotate about the axis of the cylinder 301. One end of the transmission block 504 is fixed to the fixed end of the telescopic member 501, and the other end passes through the guide groove 30131 and is inserted into the transmission groove 5031.

[0073] It should be noted that the power component is a motor, and the output shaft end of the power component is directly fixed to the center of the end of the reciprocating shaft 503.

[0074] The power piece starts to drive the reciprocating shaft 503 to rotate. During the rotation of the reciprocating shaft 503, the transmission block 504 moves through the transmission groove 5031, so that the transmission block 504 moves back and forth in the guide groove 30131, thereby driving the telescopic member 501 to move back and forth in the cylinder 301.

[0075] In some embodiments, see Figure 2 The outer wall of the driving cylinder 401 is connected to the cleaning unit 60 . The cleaning unit 60 includes a cleaning comb 601 extending along the radial direction of the sieve plate 201 . The cleaning comb 601 abuts against the upper surface of the sieve plate 201 .

[0076] The driving cylinder 401 rotates to drive the cleaning comb 601 to rotate. During the rotation process, the cleaning comb 601 is in contact with the surface of the sieve plate 201 at all times, so that the cleaning comb 601 cleans the sieve holes of the sieve plate 201, making the sieve plate 201 less likely to be blocked. At the same time, it also loosens the impurities attached to the sieve plate 201, making it easier for the impurities to be sucked away by the adsorption component.

[0077] In some embodiments, see Figure 2 and Figure 6 The cleaning comb 601 is rotatably connected to the outer wall of the driving cylinder 401. The cleaning unit 60 also includes a rotating member 602 that is transmission-connected to the cleaning comb 601. The rotating member 602 is used to drive the cleaning comb 601 to rotate with the radial direction of the screen plate 201 as the rotation axis.

[0078] It should be noted that the rotating part 602 is a waterproof motor. The rotating part 602 is fixedly mounted on the outer wall of the driving cylinder 401. The output shaft of the rotating part 602 is directly fixed to the end center of the cleaning comb 601. A water guide cover is also provided above the rotating part 602. The setting of the water guide cover prevents water from falling on the rotating part 602, thereby extending the service life of the rotating part 602.

[0079] When the cleaning comb 601 rotates around the axis of the sieve plate 201 , the rotating member 602 starts to drive the cleaning comb 601 to rotate around its own central axis, thereby enhancing the cleaning degree of the sieve plate 201 by the cleaning comb 601 .

[0080] In some embodiments, see Figure 2 The cleaning comb 601 is arranged on the front side of the impurity removing barrel 30.

[0081] It should be noted that the rotation direction of the driving cylinder 401 is forward. If the driving cylinder 401 rotates counterclockwise, the counterclockwise direction is the front side; if the driving cylinder 401 rotates clockwise, the clockwise direction is the front side. Figure 2 The middle driving cylinder 401 rotates clockwise.

[0082] After the cleaning comb 601 loosens the impurities attached to the sieve plate 201 , the loosened impurities are immediately sucked away by the suction member 302 , thereby preventing the loosened impurities from firmly adhering to the sieve plate 201 again and improving the cleaning efficiency.

[0083] In some embodiments, see Figure 1 The opening of the screen box 202 is sleeved on the outer periphery of the driving cylinder 401, and the screen box 202 and the driving cylinder 401 are detachably connected.

[0084] Optionally, the detachable connection between the screen box 202 and the driving cylinder 401 may be fixed by bolts.

[0085] The driving cylinder 401 rotates to drive the screen box 202 to rotate. During the rotation, the screen box 202 will throw out all the water inside, and the impurities in the screen box 202 will be retained, thereby reducing the residual water in the screen box 202; the screen box 202 and the driving cylinder 401 are set to be detachably connected, which is convenient for cleaning the impurities in the screen box 202.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
