Description

Technical Field

[0001] This utility model relates to the field of cooling tower circulating water treatment technology, and in particular to a cooling tower circulating water disinfection and purification device. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere to lower the water temperature. The core principle is to cool the circulating water through the evaporation of water and the heat transfer between the air and the water, so that the water temperature is reduced to a range that can be reused, thereby saving water resources and ensuring the normal operation of industrial production or air conditioning systems.

[0003] With the continuous expansion of industrial production scale and the application of large-scale air conditioning systems, cooling tower circulating water, in the long-term circulation process, becomes a breeding ground for bacteria, fungi and other microorganisms due to the suitable temperature, high humidity and rich nutrients. At the same time, suspended solids and calcium and magnesium ion impurities in the water will continue to accumulate. Therefore, a cooling tower circulating water disinfection and purification equipment is needed to achieve efficient, continuous and precise treatment of circulating water, inhibit the growth of microorganisms and remove impurities from the water.

[0004] Early cooling tower circulating water treatment consisted of a manually operated chemical tank and manual valves. The chemical tank was used to store bactericides, and the dosage was controlled by the manual valves to achieve sterilization. However, because it was difficult to accurately control the concentration by manually adding chemicals, it could lead to excessive dosage corroding equipment or insufficient dosage breeding microorganisms. To solve these problems, existing equipment has introduced ultraviolet lamps and other physical disinfection devices to reduce reliance on chemical agents and improve treatment efficiency. However, in actual use, when the ultraviolet lamps are running, calcium and magnesium ions in the circulating water will form scale on the surface of the sleeve, blocking the ultraviolet light from disinfecting the water flow. Moreover, the scale is not easy to clean, reducing the purification efficiency and failing to meet the needs of users. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 4 The present invention provides an embodiment of a cooling tower circulating water disinfection and purification device, comprising a tower body 1, which serves as the main frame of the device and provides an installation base for all internal components, forming a closed space to ensure the continuity of the cooling and purification process. A water inlet pipe 2 is connected to the bottom right side of the tower body 1, and a cleaning mechanism 3 is provided at the front end of the water inlet pipe 2. The cleaning mechanism 3 is used to remove scale formed by calcium and magnesium ions. A chemical discharge mechanism 4 is provided on the front side of the tower body 1, which is used to store and discharge chemicals for disinfection work.

[0034] The cleaning mechanism 3 includes a housing 301. The rear end of the housing 301 is connected to the front end of the water inlet pipe 2. A quartz sleeve 302 is fixedly connected to the inner side of the housing 301. The quartz sleeve 302 is a tubular structure made of transparent quartz material, fixed to the inner side of the housing 301. It serves as a protective barrier for the ultraviolet lamp assembly 303 and ensures the ultraviolet light penetration rate to guarantee the disinfection effect. An ultraviolet lamp assembly 303 is installed between the outer wall of the quartz sleeve 302 and the inner wall of the housing 301. When the ultraviolet lamp assembly 303 is powered on, it irradiates the water flow through the quartz sleeve 302 to achieve sterilization. A [missing information - likely a device or component] is fixedly connected to the front side of the inner wall of the housing 301. The connecting frame 304 provides stable support for the rotating shaft 305. The rotating shaft 305 is rotatably connected to the inner wall of the connecting frame 304. The rotating shaft 305 is the core of power transmission, which transmits the rotational kinetic energy of the turbine 306 to the scraping brush 307. The turbine 306 is fixedly connected to the front end of the rotating shaft 305. The turbine 306 converts the kinetic energy of the water flow into mechanical energy. The scraping brush 307 is fixedly connected to the left and right sides of the rear side of the outer wall of the rotating shaft 305. When the scraping brush 307 rotates with the rotating shaft 305, it closely fits the inner wall of the quartz sleeve 302 and the surface of the filter screen 3081. The scale removal component 308 is provided on the rear side of the housing 301.

[0035] The scale removal assembly 308 includes a filter screen 3081, which is used to intercept the scale and suspended solids in the water that are scraped off, preventing impurities from entering the subsequent system. The outer wall of the filter screen 3081 is fixedly connected to the rear side of the inner wall of the housing 301. The rear side of the bottom of the outer wall of the housing 301 is connected to a scale collection shell 3082. The scale collection shell 3082 collects the scale and impurities intercepted by the filter screen 3081 by gravity. The bottom of the scale collection shell 3082 is threadedly connected to a threaded cap 3083, which is convenient for manual periodic unscrewing to remove scale.

[0036] Specifically, when circulating water flows into the housing 301, the ultraviolet lamp assembly 303 disinfects the water flow through the quartz sleeve 302. During this process, calcium and magnesium ions form scale and adhere to the inner wall of the quartz sleeve 302. At the same time, the water flow impacts the turbine 306, using the kinetic energy of the water flow to drive the turbine 306 to rotate. This rotation is then transmitted through the shaft 305. The scraping brush 307 at the rear end of the shaft 305 rotates synchronously with the shaft 305. The scraping brushes 307 on both sides are in close contact with the inner wall of the quartz sleeve 302, continuously scraping away impurities through the bristles. Scale formed on the pipe surface due to calcium and magnesium ion deposition is simultaneously cleaned by the rear side of two scraping brushes 307 to remove impurities trapped on the filter screen 3081, thus preventing increased water flow resistance due to filter screen 3081 clogging. The scraped scale and suspended matter in the water are intercepted by the filter screen 3081 and fall into the scale collection shell 3082 at the bottom under gravity, thereby separating the scale from the water flow. When cleaning is required, the threaded cap 3083 at the bottom of the scale collection shell 3082 is unscrewed to drain the deposited scale, improving the purification efficiency and operational stability of the equipment.

[0037] Reference Figure 1 and Figure 5 The chemical discharge mechanism 4 includes a three-way pipe 401. The main pipe of the three-way pipe 401 is connected to the water inlet pipe 2, and the side pipe is connected to a solenoid valve 402. The rear end of the three-way pipe 401 is connected to the housing 301. A solenoid valve 402 is installed on one side of the outer wall of the three-way pipe 401. When the solenoid valve 402 is opened, it connects the chemical storage tank 404 and the three-way pipe 401, allowing the chemical to flow in. One end of the three-way pipe 401 is connected to a connecting hose 403, which flexibly connects the chemical storage tank 404 and the three-way pipe 401. The front of the outer wall of the tower body 1 A storage tank 404 is provided on the right side. The storage tank 404 is used to store disinfectant. The other end of the connecting hose 403 is connected to the bottom right side of the outer wall of the storage tank 404. An injection pipe 405 is connected to the front side of the outer wall of the storage tank 404. The injection pipe 405 is an external agent replenishment channel. A second solenoid valve 406 is provided on the outer wall of the injection pipe 405. The second solenoid valve 406 is opened when replenishing the agent to allow the external agent to be drawn in, and closed when discharging the agent to prevent the agent in the tank from overflowing. A pressurization component 407 is provided inside the storage tank 404.

[0038] The pressurization assembly 407 includes a cylinder 4071. The bottom of the cylinder 4071 is fixedly connected to the top of the medicine storage tank 404. The output end of the cylinder 4071 passes through the top of the medicine storage tank 404 and is fixedly connected to a piston 4072. The cylinder 4071 generates positive pressure by pressing down through the piston 4072, which squeezes out the medicine. The piston 4072 generates negative pressure by rising, which draws in external medicine.

[0039] Specifically, when the circulating water needs to be replenished with chemicals to cooperate with ultraviolet disinfection, solenoid valve 1 402 opens and solenoid valve 2 406 closes. The piston 4072 at the cylinder output end presses down in the chemical storage tank 404, forming positive pressure. The chemicals flow into the three-way pipe 401 in one direction through the connecting hose 403, which can prevent the circulating water from backflowing and contaminating the chemical storage tank 404. By controlling the pushing amount of cylinder 4071, the input amount of chemicals can be controlled. When it is necessary to replenish the chemicals, solenoid valve 1 402 closes and solenoid valve 2 406 opens. The piston 4072 rises to generate negative pressure, and the chemicals are drawn from the external chemical tank through the injection pipe 405 to quickly replenish the chemicals.

[0040] Reference Figure 1 , Figure 2 and Figure 3 A bracket 5 is fixedly connected to the top of the inner wall of the tower body 1. The bracket 5 provides rigid support for the motor 6. The top of the bracket 5 is fixedly connected to the motor 6, which provides a power source and controls the air volume generated by the fan 7. The output end of the motor 6 passes through the top of the bracket 5 and is fixedly connected to the fan 7.

[0041] The rear end of the water inlet pipe 2 is connected to the water delivery pipe 8. One end of the water delivery pipe 8 is connected to the water inlet pipe 2, and the other end extends upward to the top of the tower body 1. It is responsible for delivering the circulating water to be cooled to the water distributor 9. The top end of the water delivery pipe 8 is connected to the water distributor 9. The water distributor 9 atomizes the circulating water into water droplets through the nozzle and evenly sprays it onto the packing layer below.

[0042] A fixing ring 10 is fixedly connected to the lower part of the inner wall of the tower body 1. The fixing ring 10 is the bearing base. The connecting plate 12 and the connecting ring 11 provide support for the installation of the packing. A connecting ring 11 is provided on the lower part of the outer wall of the water pipe 8. Multiple connecting plates 12 are fixedly connected to the inner wall of the fixing ring 10. The other end of the multiple connecting plates 12 is fixedly connected to the outer wall of the connecting ring 11.

[0043] A ladder 13 is fixedly connected to the front top of the tower body 1. The ladder 13 facilitates the maintenance of the motor 6, fan 7 and other top components. Multiple anti-slip pads 14 are provided on the inner side of the ladder 13 to prevent maintenance personnel from slipping when climbing in rainy or humid environments.

[0044] Specifically, the motor 6 is fixed on the top bracket 5. After starting, it drives the fan 7 to rotate at high speed, creating a negative pressure inside the tower body 1. Cold air from the outside is drawn in from the bottom air inlet and fully exchanges heat with the falling circulating water as it rises along the tower body 1. The hot air is finally discharged from the top fan 7, completing the heat dissipation cycle. The circulating water flows into the water supply pipe 8 through the water inlet pipe 2 and is evenly sprayed onto the lower packing layer through the water distributor 9 at the top of the water supply pipe 8. The top of the fixing ring 10, the connecting ring 11, and the connecting plate 12 are used to place the packing layer. The ladder 13 on the front side of the top of the tower body 1 provides a passage for maintenance personnel. The rubber anti-slip pad 14 on the inside of the ladder 13 prevents slipping when climbing.

[0045] Working principle: When circulating water flows into the housing 301, the ultraviolet lamp assembly 303 disinfects the water flow through the quartz sleeve 302, while calcium and magnesium ions form scale that adheres to the inner wall of the quartz sleeve 302. Simultaneously, the water flow impacts the turbine 306, using the kinetic energy of the water flow to drive the turbine 306 to rotate. This rotation is then transmitted through the shaft 305. The scraping brush 307 at the rear end of the shaft 305 rotates synchronously with the shaft 305. The scraping brushes 307 on both sides are in close contact with the inner wall of the quartz sleeve 302, thus... The brush bristles continuously scrape away the scale formed by calcium and magnesium ion deposits on the surface of the sleeve. At the same time, the rear sides of the two scraping brushes 307 simultaneously clean the impurities trapped on the filter screen 3081, preventing the filter screen 3081 from becoming clogged and increasing water flow resistance. The scraped scale and suspended matter in the water are intercepted by the filter screen 3081 and fall into the scale collection shell 3082 at the bottom under the action of gravity, realizing the separation of scale and water flow. When cleaning is required, unscrew the threaded cap 3083 at the bottom of the scale collection shell 3082 to discharge the deposited scale.

[0046] Furthermore, when the circulating water needs to be supplemented with chemicals in conjunction with ultraviolet disinfection, solenoid valve 1 402 opens and solenoid valve 2 406 closes. The piston 4072 at the cylinder output end presses down in the storage tank 404 to create positive pressure. The chemicals flow into the three-way pipe 401 in one direction through the connecting hose 403, preventing the circulating water from backflowing and contaminating the storage tank 404. The amount of chemicals input is controlled by controlling the advance of the cylinder 4071. When chemicals need to be replenished, solenoid valve 1 402 closes and solenoid valve 2 406 opens. The piston 4072 rises to generate negative pressure, and chemicals are drawn in from the external chemical tank through the injection pipe 405.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
