[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] First Embodiment

[0027] Please refer to the following: Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a novel circulating water cooling device provided by this utility model; Figure 2 for Figure 1 The diagram shows a cross-sectional view of the housing. A novel circulating water cooling device includes:

[0028] The water collection tank 1 has a drain pipe 7 fixedly installed inside it, a filter layer 6 is provided inside it, a corrosion rate sensor 14 is fixedly installed inside it, a conductivity sensor 15 is fixedly installed inside it, and a turbidity sensor 22 is fixedly installed inside it.

[0029] Box 2, which is located on the top of the water collection tank 1, has two water inlet pipes 3 fixedly installed on one side of the box 2, and multiple nozzles 4 fixedly installed on the surface of the two water inlet pipes 3. The box 2 is filled with packing material 5.

[0030] Storage box 8 is located on top of the water collection tank 1. A conveying pipe 9 is fixedly installed inside the storage box 8, and a conveying pump 10 is fixedly installed at one end of the conveying pipe 9.

[0031] The filler 5 is made of plastic or ceramic materials with higher specific surface area and better hydrophilicity to increase the contact area between water and air and improve evaporative cooling efficiency.

[0032] The corrosion rate sensor 14 can detect the corrosion rate of metal in water to determine whether a corrosion inhibitor needs to be added. For example, an electrochemical corrosion rate sensor is based on electrochemical principles and monitors the corrosion rate of metal in real time by measuring the electrochemical parameters of the metal electrode in water. When the corrosion rate exceeds the set threshold, it indicates that the metal corrosion is intensifying, and at this time it may be necessary to add a corrosion inhibitor to slow down the corrosion.

[0033] The conductivity sensor 15 can measure the ion conductivity in the water, reflecting the content change of dissolved salts and other substances in the water. The content of calcium, magnesium and other ions in the water is closely related to fouling. The increase of conductivity may mean that the ion concentration in the water increases, the risk of fouling increases, and then it prompts that the scale inhibitor may need to be added.

[0034] The turbidity sensor 22 measures the turbidity of the water, reflecting the content of suspended particles and microorganisms in the water. The large number of microorganisms can increase the turbidity of the water. When the turbidity exceeds a certain range, it may mean that there are many microorganisms in the water, and a bactericide needs to be added to control the growth of microorganisms.

[0035] The filter layer 6 adopts multi-stage filtration, and coarse filtration, fine filtration and ultrafiltration are arranged in sequence. Through layer-by-layer filtration, suspended particles, impurities and microorganisms in the water are removed comprehensively, effectively preventing the cooling tower from being blocked and scaled.

[0036] In the coarse filtration stage, the preliminary filtration is mainly realized by the filter screen. Considering the working environment of the cooling tower, the filter screen is usually made of high-strength, corrosion-resistant metal material or high-quality plastic material. The mesh size is accurately designed, which can effectively intercept larger suspended particles in the water, such as leaves, insect carcasses, and larger impurities such as rust and welding slag generated due to equipment aging in the surrounding environment of the cooling tower. If these substances enter the interior of the cooling tower, they will not only block the pipeline and nozzle, affect the uniform distribution of water and the cooling effect, but also may cause wear to the internal structure of the cooling tower, reducing the service life of the equipment.

[0037] In the fine filtration stage, activated carbon or quartz sand can be selected as the filter medium according to actual needs. For the case that the organic pollutants and odor in the water quality are more serious, activated carbon is an excellent choice. Activated carbon has rich pore structure and large specific surface area, which can effectively remove organic matter, residual chlorine, color and part of heavy metal ions in the water through the dual action of physical and chemical adsorption. In the water circulation of the cooling tower, the removal of these harmful substances can reduce the breeding environment of microorganisms and inhibit the reproduction of microorganisms. Quartz sand plays an important role in fine filtration due to its high hardness and stable chemical properties. The fine gap formed between the quartz sand particles can further intercept fine suspended particles and colloidal substances in the water, making the water quality more clear and pure, reducing the wear of the internal components of the cooling tower by impurities in the water, and reducing the possibility of scaling.

[0038] The ultrafiltration membrane technology adopted in the ultrafiltration stage is particularly crucial for water quality purification of the cooling tower. A large number of microorganisms such as bacteria, algae and fungi are prone to breed in the cooling tower, which not only affects the water quality, but also forms biological sludge inside the cooling tower, blocks the pipeline and filler and reduces the cooling efficiency. The pore size of the ultrafiltration membrane is extremely small, generally between 0.001-0.1 microns, which can accurately intercept microorganisms in water and remove part of macromolecular organic matter. Under the driving of pressure, water molecules pass through the ultrafiltration membrane smoothly, while impurities such as microorganisms are intercepted on one side of the membrane, thereby effectively controlling the number of microorganisms in the cooling tower, keeping the inside of the cooling tower clean and ensuring the stable heat dissipation performance of the cooling tower, prolonging the maintenance cycle and service life of the equipment.

[0039] Therefore, through the synergistic work of the multi-stage filtration system of coarse filtration, fine filtration and ultrafiltration of the filter layer 6, high-quality circulating water can be provided for the cooling tower, the long-term stable and efficient operation of the cooling tower is ensured, the maintenance cost and energy consumption of the equipment are reduced, and the comprehensive benefit of the entire cooling system is improved.

[0040] The output end and the input end of the conveying pump 10 are fixedly installed with the conveying pipes 9, and the other ends of the two conveying pipes 9 are fixedly installed in the inside of the storage box 8 and the water collecting pool 1 respectively.

[0041] The conveying pump 10 can be a metering pump, a magnetic force pump, a centrifugal pump, etc., which is used to automatically add chemical agents such as corrosion inhibitors, scale inhibitors and bactericides according to the monitoring result of water quality, and the chemical agents in the storage box 8 are conveyed into the filtered water in the water storage pool through the conveying pump 10 cooperating with the conveying pipe 9, so as to ensure the stability of the water quality and the normal operation of the system.

[0042] The metering pump is a pump that can accurately control the flow, also called a quantitative pump, which can accurately convey a certain dose of agents according to the actual demand of the water treatment system, and the addition amount of corrosion inhibitors, scale inhibitors and bactericides can be accurately controlled through the metering pump, so as to achieve the best treatment effect and avoid waste.

[0043] A stirring motor 11 is fixedly installed on one side of the water collecting pool 1, the output end of the stirring motor 11 is connected with a stirring rod 12 through a shaft coupling, and a plurality of stirring blades 13 are fixedly connected to the surface of the stirring rod 12.

[0044] The stirring rod 12 is rotatably connected to the inside of the water collecting pool 1, which is used to drive the stirring rod 12 connected with the plurality of stirring blades 13 to rotate to one side after the stirring motor 11 is started, so as to stir the water in the water collecting pool 1, and make the chemical agents fully mix with the water.

[0045] One end of the stirring rod 12 is rotatably connected to one side of the inner wall of the water collecting pool 1, and a section of the surface is rotatably connected to the inside of the water collecting pool 1.

[0046] The stirring rod 12 is rotated and sealed to the water collection tank 1 by an oil seal.

[0047] An exhaust duct is fixedly connected to the top of the housing 2, and a fan 15 is fixedly installed inside the exhaust duct 14.

[0048] Fan 15 is used to increase the exhaust efficiency of enclosure 2.

[0049] The working principle of the novel circulating water cooling device provided by this utility model is as follows:

[0050] In use, the external water pump passes through the inside of the inlet pipe 3, and then sprays water out through the inlet pipe 3 in conjunction with multiple nozzles 4. The water is evenly sprayed onto the packing material 5 through the multiple nozzles 4. Air enters from the bottom of the box 2 and comes into countercurrent contact with the falling hot water. The hot water forms a water film on the surface of the packing material 5, and heat is transferred to the air through evaporation and convection, thus lowering the water temperature.

[0051] The cooled water is collected in the water collection tank 1 at the bottom of the cooling tower. The delivery pump 10, together with the delivery pipe 9, delivers the chemical agents inside the storage tank 8 into the filtered water in the water collection tank 1.

[0052] Compared with related technologies, the novel circulating water cooling device provided by this utility model has the following advantages:

[0053] Beneficial effects:

[0054] This utility model provides a novel circulating water cooling device. The filter layer 6 is used to remove suspended particles, impurities and microorganisms from the cooled water, preventing clogging and scaling. At the same time, based on the water quality monitoring results, chemical agents such as corrosion inhibitors, scale inhibitors and bactericides are automatically added. The chemical agents inside the storage tank 8 are transported into the filtered water in the water storage tank through the delivery pump 10 and the delivery pipe 9, so as to ensure the stability of water quality and the normal operation of the system.
