Description

Technical Field

[0001] The present invention relates to the technical field of cooling devices, and more specifically, to a modular cooling device with disassemblable and recyclable bamboo grid fillers. Background Art

[0002] The core of the traditional cooling tower spray cooling system lies in gas-liquid contact heat transfer, which realizes the cooling of high-temperature gas through means such as direct spraying, indirect heat exchange, and packing strengthening. For example, in the patent document of a temperature reduction and purification device for high-temperature waste gas with the publication number CN209286990U, the direct spraying method is used to cool the high-temperature gas.

[0003] To enhance heat exchange, a packing layer (such as bamboo grid, plastic, or metal packing) is often arranged in the spray tower. By increasing the gas-liquid contact area and prolonging the residence time, the heat exchange efficiency is improved. The bamboo grid packing is a kind of packing used in cooling towers, which is composed of bamboo or the shape of bamboo, usually arranged in a grid pattern. The design of this packing aims to increase the surface area inside the cooling device so that more cooling medium can contact the high-temperature air. However, after long-term use, organic substances such as dirt, algae, and bacteria will appear on the surface of the bamboo grid packing and form a biofilm, resulting in a decrease in the heat exchange efficiency of the packing. And because the bamboo grid packing is often fixedly installed in the cooling device, during cleaning, the equipment needs to be shut down, affecting the cooling of high-temperature gas. It is impossible to utilize the high-temperature property of the high-temperature gas to not only deeply clean the bamboo grid packing but also pre-cool the high-temperature gas under the premise of continuously cooling the high-temperature gas to jointly improve the gas cooling effect. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a modular cooling device with disassemblable and recyclable bamboo grid fillers.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A modular cooling device with disassemblable and recyclable bamboo grid fillers, including a liquid barrel, a detachable annular cover, a sealing ring, and a sealing cover. The liquid barrel, the detachable annular cover, the sealing ring, and the sealing cover are fixedly connected in sequence from bottom to top. A cylindrical frame is arranged at the center of the sealing ring. A plurality of groups of vertical plates are circularly arranged on the circumferential outer wall of the cylindrical frame. Bamboo grid fillers are installed between two adjacent vertical plates. An arc-shaped plate is connected to the circumferential outer wall of the bamboo grid filler, and the arc-shaped plate is fixedly installed on the vertical plate through bolts. A packing cleaning component for cleaning the bamboo grid filler is arranged outside the cylindrical frame. The packing cleaning component includes two groups of triangular sealing covers. One group of triangular sealing covers is fixedly connected to the tops of two adjacent vertical plates, and the other group of triangular sealing covers is fixedly connected to the bottoms of two adjacent vertical plates, and the two groups of triangular sealing covers are arranged corresponding to each other. A cleaning area is formed between the inner walls of two groups of the triangular sealing covers and the inner walls of two adjacent vertical plates. A first serpentine tube is arranged inside the upper triangular sealing cover, and a second serpentine tube is arranged inside the lower triangular sealing cover.

[0006] Further, the output end of the second serpentine tube is communicated with the input end of the first serpentine tube through a third smoke pipe. The input end of the second serpentine tube is connected with a first air inlet pipe. The output end of the first serpentine tube is connected with an air pump through a second smoke pipe.

[0007] Further, the output end of the air pump is connected with a second air inlet pipe through a first smoke pipe. The second air inlet pipe is inserted into the interior of the liquid bucket. A first control valve is arranged on the outer wall of the input end of the first serpentine tube.

[0008] Further, the bottoms of multiple groups of the bamboo grid packings are jointly connected with a limiting ring, and the limiting ring is fixedly connected with the inner wall of the detachable annular cover.

[0009] Further, a cleaning pipe is vertically inserted into the top wall of the upper triangular sealing cover. The input end of the cleaning pipe extends outside the sealing ring and is connected with a two-way pipe. Multiple cleaning nozzles are arranged at the output end of the cleaning pipe. A third control valve is arranged on the outer wall of the cleaning pipe.

[0010] Further, a sewage discharge pipe is inserted into the outer wall of the lower triangular sealing cover. The output end of the sewage discharge pipe extends outside the liquid bucket. A second control valve is arranged on the outer wall of the sewage discharge pipe.

[0011] Further, a driving shaft is fixedly arranged at the bottom of the cylindrical frame. A motor is fixedly arranged at the bottom of the driving shaft, and the motor is fixedly connected with the inner wall of the detachable annular cover.

[0012] Further, a water pump is arranged on the outer wall of the liquid bucket. The input end of the water pump is connected with a liquid pipe, and the output end of the liquid pipe is inserted below the liquid bucket. The output end of the water pump is connected with an infusion pipe. The output end of the infusion pipe is inserted into the interior of the sealing ring and is connected with a spray ring. Multiple spray nozzles are arranged at the output end of the spray ring.

[0013] Further, a blower is installed above the sealing cover. The output end of the blower is connected with a smoke outlet, and the smoke outlet extends outside the sealing cover.

[0014] The technical effects and advantages of the present invention: 1. The present invention utilizes the high-temperature property of high-temperature gas. The high-temperature gas passes through the cleaning area to heat the cleaning agent, improving the soaking and scale-removing effect of the cleaning agent. After the soaking time, the control valve II on the sewage discharge pipe is opened to complete the initial discharge of sewage. Subsequently, the algae substances above the packing are soaked with a bactericide, and then the sewage is discharged through the sewage discharge pipe. Then, the packing is subjected to an overpressure impact with purified water to complete the cleaning. Finally, the packing is dried at high temperature with high-pressure air flow. In the whole process, not only is the hot air conveyed through the pipeline used to accelerate cleaning and drying, but also the high-temperature air is pre-cooled to accelerate its subsequent cooling efficiency.

[0015] 2. The present invention controls the operation of the motor to drive the drive shaft to rotate. When the drive shaft rotates, it drives the cylindrical frame and the vertical plate to rotate. Therefore, any packing can be rotated into the interior of the cooling area for cleaning the cooling area. The cleaned bamboo grid packing continues to cool down the high-temperature gas. That is, on the premise of the normal operation of the equipment, the bamboo grid packing can be cleaned, improving the stability and efficiency of the equipment operation.

[0016] 3. The present invention starts from two aspects: continuous operation and thorough cleaning. That is, on the premise of the continuous operation of the equipment, the high-temperature property of the high-temperature gas is utilized to preheat the cleaning agent and bactericide in the cleaning area, improving the soaking and cleaning and sterilization effects on the bamboo grid packing, and drying the bamboo grid packing at high temperature through the high-temperature property. In this process, not only is the cleaning of the bamboo grid packing accelerated, but also the high-temperature gas is pre-cooled and cooled. The two cooperate with each other to jointly improve the cooling effect of the cooling device. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1: Please refer to Figures 1 - 7 As shown, for the problem of not only deeply cleaning the bamboo grid packing but also pre-cooling the high-temperature gas by utilizing the high-temperature property of the high-temperature gas on the premise of continuously cooling the high-temperature gas, the following solution can be adopted; In this embodiment, a detachable and recyclable modular cooling device for bamboo grid packing includes a liquid bucket 1, a removable annular cover 2, a sealing ring 3, and a sealing cover 4. The liquid bucket 1, the removable annular cover 2, the sealing ring 3, and the sealing cover 4 are fixedly connected in sequence from bottom to top and form a cooling space; It should be supplemented and explained here that: a removable plate 5 is arranged on the outer side of the removable annular cover 2, and the position of the removable plate 5 corresponds to the arc plate 15 inside the cleaning area. After opening the removable plate 5 and then removing the arc plate 15, the bamboo grid packing 12 inside the cleaning area can be taken out; And a cooling tool for cooling the coolant is arranged below the liquid bucket 1, which belongs to the prior art and only needs to have a cooling function for the coolant, so it is not shown in the figure; A cylindrical frame 13 is provided at the center of the sealing ring 3. A plurality of vertical plates are circularly arranged on the circumferential outer wall of the cylindrical frame 13. A plurality of sets of bamboo grid packings 12 are installed between two adjacent vertical plates. A limiting ring is connected to the bottoms of the plurality of sets of bamboo grid packings 12. Here, the limiting ring is in contact with the bottoms of the bamboo grid packings 12 to play a limiting role, and the limiting ring is fixedly connected to the inner wall of the detachable annular cover 2. An arc-shaped plate 15 is connected to the circumferential outer wall of the bamboo grid packing 12. The arc-shaped plate 15 is fixedly installed on the vertical plate by bolts. It can be seen from this that a modular cooling area is formed between the inner wall of the arc-shaped plate 15 and the inner walls of two adjacent vertical plates. The cooling area is used to fill the bamboo grid packing 12; Please refer to Figures 1 - 7 As shown, a packing cleaning assembly 6 for cleaning the bamboo grid packing 12 is provided outside the cylindrical frame 13. The packing cleaning assembly 6 includes two sets of triangular sealing covers 61. One set of triangular sealing covers 61 is fixedly connected to the tops of two adjacent vertical plates, and the other set of triangular sealing covers 61 is fixedly connected to the bottoms of two adjacent vertical plates. And the two sets of triangular sealing covers 61 are arranged corresponding to each other; Please refer to Figures 1 - 7 As shown, a cleaning area is formed between the inner walls of the two sets of triangular sealing covers 61 and the inner walls of two adjacent vertical plates. A first serpentine pipe 67 is arranged in the upper triangular sealing cover 61, and a second serpentine pipe 610 is arranged in the lower triangular sealing cover 61. The output end of the second serpentine pipe 610 is communicated with the input end of the first serpentine pipe 67 through a third smoke pipe 68. The input end of the second serpentine pipe 610 is connected with a first air inlet pipe 63. The output end of the first serpentine pipe 67 is connected with an air pump 65 through a second smoke pipe 66. The output end of the air pump 65 is connected with a second air inlet pipe 69 through a first smoke pipe 64. The second air inlet pipe 69 is inserted into the interior of the liquid barrel 1; A control valve one is arranged on the outer wall of the input end of the first serpentine pipe 67; Please refer to Figure 7 As shown, a cleaning pipe 611 is vertically inserted into the top wall of the upper triangular sealing cover 61. The input end of the cleaning pipe 611 extends outside the sealing ring 3 and is connected with a two-way pipe. The output end of the cleaning pipe 611 is provided with a plurality of cleaning nozzles 612; A control valve three is arranged on the outer wall of the cleaning pipe 611; Please refer to Figure 2 、 Figures 4 - 6 As shown, a sewage discharge pipe 62 is inserted into the outer wall of the lower triangular sealing cover 61. The output end of the sewage discharge pipe 62 extends outside the liquid barrel 1, and a control valve two is arranged on the outer wall of the sewage discharge pipe 62; It should be noted here that: First, the gas enters the first serpentine tube 67 through the first air inlet pipe 63. When the first control valve is opened, the gas passes through the lower serpentine tube and then enters the third smoke transmission pipe 68, and then enters the lower serpentine tube through the third smoke transmission pipe 68, and is then discharged through the second smoke transmission pipe 66. After being conveyed by the air pump 65, the gas first enters the first smoke transmission pipe 64 and then enters the second air inlet pipe 69, and then enters above the liquid storage tank for cooling. In the above steps, above the cleaning area, the cleaning agent is first injected through the cleaning pipe 611 and the cleaning nozzle 612, and is heated by the high-temperature gas conveyed by the first serpentine tube 67 and the second serpentine tube 610 to improve the soaking effect of the cleaning agent. The time is generally 30-60 minutes. After the soaking time, the second control valve on the sewage discharge pipe 62 is opened to complete the initial discharge of the sewage. Subsequently, the algae substances above the packing are soaked with a bactericide, generally for 20-30 minutes, and then the sewage is discharged through the sewage discharge pipe 62. Subsequently, the packing is impacted with overpressure by clean water to complete the cleaning. Finally, the packing is air-dried by high-pressure air flow. In the whole process, not only the hot air conveyed by the pipeline is used to accelerate the cleaning and drying, but also the high-temperature air is pre-cooled to accelerate its subsequent cooling efficiency. Please refer to Figure 2 、 Figures 4 - 6 As shown, a drive shaft 14 is fixedly arranged at the bottom of the cylindrical frame 13, and a motor is fixedly arranged at the bottom of the drive shaft 14, and the motor is fixedly connected to the inner wall of the detachable annular cover 2. It should be noted here that: By controlling the motor to work, the drive shaft 14 is driven to rotate. When the drive shaft 14 rotates, it drives the cylindrical frame 13 and the vertical plate to rotate, and rotates the packing into the interior of the cooling area to clean the cooling area, that is, multiple groups of packing can be cleaned, and the device does not need to be shut down during the whole process, and the high-temperature gas can still be cooled. It should be supplemented here that: During the process of the bamboo grid packing 12 rotating into the cleaning area, the small amount of high-temperature gas entering the interior of the cleaning area can be ignored. Please refer to Figures 2 - 3 As shown, a water pump is arranged on the outer wall of the liquid bucket 1. The input end of the water pump is connected with a liquid pipe, and the output end of the liquid pipe is inserted below the liquid bucket 1. The output end of the water pump is connected with an infusion pipe 11, and the output end of the infusion pipe 11 is inserted into the interior of the sealing ring 3 and is connected with a spray ring 9, and multiple spray nozzles 10 are arranged at the output end of the spray ring 9. It should be noted here that: The water pump sucks the liquid below the liquid bucket 1, transfers it to the interior of the spray ring 9 through the infusion pipe 11, and discharges it through the spray nozzles 10 below the spray ring 9 to cool the air in the packing. Please refer to Figures 2 - 3As shown, a blower 7 is installed above the sealing cover 4. The output end of the blower 7 is connected to a smoke outlet 8, and the smoke outlet 8 extends to the outside of the sealing cover 4; The present invention starts from two aspects: continuous operation and thorough cleaning. That is, on the premise of continuous operation of the equipment, using the high-temperature property of the high-temperature gas to preheat the cleaning agent and bactericide in the cleaning area, improving the soaking cleaning and sterilization effect on the bamboo grid filler 12, and drying the bamboo grid filler 12 at high temperature through the high-temperature property. During this process, not only the cleaning of the bamboo grid filler 12 is accelerated, but also the high-temperature gas is cooled in advance. The two cooperate with each other to jointly improve the cooling effect of the cooling device; The working principle of the present invention: The high-temperature gas enters the cooling space through the first intake pipe 63. Under the action of the blower 7, the high-temperature gas moves upward and is discharged through the smoke outlet 8. During this period, the water pump continuously transports the liquid in the liquid barrel 1 to the spray ring 9 and discharges it through a plurality of spray heads 10 to spray and cool the high-temperature gas in the bamboo grid filler 12. The cooled gas is discharged through the smoke outlet 8.
