Description

Technical Field

[0001] This utility model relates to the field of cooling tower inlet water treatment technology, specifically to an inlet water treatment device for cooling towers. Background Technology

[0002] In existing cooling tower cooling water circulation systems, the water used may contain impurities such as suspended solids and algae. If no preventive measures are taken, these impurities will deposit on the inner walls of the pipes over a long period of time, forming scale. Once scale accumulates on the inner walls of the pipes, it can cause fluctuations in flow and pressure during the delivery of cooling water to the water distributor. In severe cases, it can also corrode equipment and pipelines, endangering safe production. In addition, when cooling water is delivered to the cooling tower, it can cause blockage of the water distribution holes in the water distributor of the cooling tower.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] As attached Figure 2 and attached Figure 3 As shown, a water inlet treatment device for a cooling tower includes a treatment box 1. Multiple sets of water inlet pipes 2 are installed through the upper side wall of the treatment box 1. A water control valve 19 is installed on the water inlet pipe 2, and the opening and closing of the water inlet pipe 2 and the water inlet speed are controlled by the water control valve 19.

[0026] The water inlet pipe 2 is located inside the treatment tank 1, and a filter cartridge 3 is fitted on the outside of the filter cartridge 3. A positioning frame 4 is fitted on the outside of the filter cartridge 3 to support the filter cartridge 3. Cooling water is filtered through the filter cartridge 3. One end of the positioning frame 4 is fitted on the outside of the water inlet pipe 2, and a sealing gasket 12 is provided between them. The sealing gasket 12 seals the positioning frame 4 and the water inlet pipe 2 to prevent impurities in the cooling water from leaking out.

[0027] To facilitate the detection and cleaning of impurities inside filter cartridge 3, as shown in the attached document... Figure 1 Appendix Figure 3 Appendix Figure 4 and attached Figure 5As shown, a water pressure monitor 9 is installed on the inner side of one end of the positioning frame 4, and a battery box 6 is installed on the outer side of the frame, which is sealed through the treatment box 1. A pressure receiving processor 11 connected to the water control valve 19 and the water pressure monitor 9 is installed on the outer side of the battery box 6. When impurities accumulate inside the filter cartridge 3, the filtration speed of the filter cartridge 3 is affected. Under the same water inflow, the water pressure inside the filter cartridge 3 will increase slightly. The water pressure monitor 9 monitors the water pressure inside the filter cartridge 3 in real time. The water pressure monitor 9 is numbered and transmits the monitoring data to the pressure receiving processor 11. When the pressure receiving processor 11 detects that the water pressure data in the filter cartridge 3 exceeds the set normal water pressure value, it controls the corresponding water control valve 19 to close. After water volume calculation, it controls the other water control valves 19 to keep the water inflow inside the treatment box 1 constant. The water control valve 19 is a manual-automatic integrated water control valve, which can also be closed and opened by the operator in special circumstances.

[0028] A threaded connecting pipe 5 is installed inside the battery box 6 and outside the positioning frame 4. A threaded mounting cylinder 7, which mates with the threaded connecting pipe 5 and the positioning frame 4, passes through the side wall of the treatment box 1. A handle 8 is installed on the outside of the battery box 6. After the water control valve 19 corresponding to the filter cartridge 3 that needs to be cleaned is closed, the handle 8 is rotated. The handle 8 drives the battery box 6 and the threaded connecting pipe 5 to rotate, so that the threaded connecting pipe 5 is taken out from the threaded mounting cylinder 7, and the filter cartridge 3 is pulled out from the threaded mounting cylinder 7 for cleaning. Then, by operating in the above process direction, the filter cartridge 3 is installed inside the treatment box 1 to continue the filtration work.

[0029] To ensure that the flow rate and pressure of cooling water remain stable during the distribution process, as shown in the attached document... Figure 1 and attached Figure 2 As shown, a pressure sensor 16 is installed at the bottom of the processing tank 1. A float 17 is installed on the top of the pressure sensor 16 via a connecting rope. The float 17 floats on the water surface. When the water level inside the processing tank 1 is too high, the float 17 moves the top of the pressure sensor 16 upward. At this time, the pressure detected by the pressure sensor 16 decreases. A water level monitor 18 is installed on the outside of the housing of the pressure sensor 16. When the water level is too low, the water level monitor 18 detects an abnormal minimum water level. A data receiving processor 10 connected to the pressure sensor 16 and the water level monitor 18 is installed on the outside of the processing tank 1. Both the pressure sensor 16 and the water level monitor 18 send the monitored data to the data receiving processor 10. The data receiving processor 10 processes and transmits the data to the control terminal to remind the staff to check the equipment.

[0030] An inclined water guide plate 15 is installed on the inner side of the treatment tank 1. The inclined water guide plate 15 is located below the multiple sets of water inlet pipes 2 and above the float 17. The water discharged from the water inlet pipes 2 is sent to the inner wall of the treatment tank 1 through the inclined water guide plate 15, and flows along the inner wall of the treatment tank 1 to the bottom of the treatment tank 1, reducing the height of the water surface inside the treatment tank 1 and affecting the height of the float 17.

[0031] As attached Figure 1 As shown, a drain pump 13 is installed through the lower side wall of the treatment tank 1. An extension pipe is provided at the water inlet of the drain pump 13 and extends to the bottom of the treatment tank 1. After the drain pump 13 is started, the water at the bottom of the treatment tank 1 is drawn out through the extension pipe. The drain pipe of the drain pump 13 is connected to a water distribution pipe 14, and the cooling water is sent to multiple cooling towers for use through the water distribution pipe 14. The side walls of the treatment tank 1 are all made of heat insulation material, which will not cause the temperature of the cooling water to rise.
