[0002] Circulating cooling water is an integral part of chemical production. The circulating water is pressurized by the circulating water pump and sent to the heat exchangers of the production equipment. After use, the temperature rises. Most of the circulating water returns to the cooling tower nozzle, is atomized and sprayed, and is directly cooled by heat exchange with the air before returning to the circulating water pool.

[0003] Due to the repeated use of water, salts in the water are concentrated, CO2 is lost, and dust in the air enters the circulating water, causing microorganisms to multiply in large numbers, causing scaling, corrosion and slime in the heat exchange equipment, and ultimately leading to a decrease in the heat exchange efficiency of the heat exchange equipment or accidents. Regular cleaning and descaling are required, which is cumbersome and will affect production efficiency. It does not have the function of automatic proportioning and injection treatment.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figure 1-4 , a pharmaceutical treatment system for injecting pharmaceuticals into circulating cooling water includes a water pool 1, four corners of the bottom end of the water pool 1 are vertically fixedly connected to support frames 2, the top of the support frame 2 is fixedly connected to an air chamber 12, the rear end of the right side of the air chamber 12 is fixedly connected to a hot water inlet pipe 11, the front end of the hot water inlet pipe 11 is longitudinally fixedly connected to multiple groups of spray pipes 17, the top of the spray pipe 17 is equipped with multiple groups of nozzles 18, the top of the air chamber 12 is equipped with an exhaust fan 13, the bottom end of the air chamber 12 is provided with a packing layer 19, the left side of the water pool 1 is fixedly connected to a water outlet pipe 23, and the right side of the water pool 1 is provided with a pharmaceutical treatment component for automatic injection;

[0026] See also Figure 1-4 , the circulating cooling water injection reagent treatment system also includes a reagent treatment component, which includes a fixed frame 3, the fixed frame 3 is fixedly connected to the right side of the water pool 1, and three groups of reagent bottles 4 are horizontally placed at the bottom end of the fixed frame 3. Three groups of metering pumps 5 are installed on the top of the fixed frame 3. The bottom end of the metering pump 5 is provided with a drug extraction pipe 6, and the top of the metering pump 5 is provided with a drug delivery pipe 7. A PLC programmable logic controller 9 is installed on the right side of the top of the fixed frame 3. The outside of the hot water inlet pipe 11 is sleeved with an external clamp-on flow meter 8, and the top of the hot water inlet pipe 11 is plugged with three groups of one-way valves 10;

[0027] The bottom end of the drug extraction tube 6 passes through the top of the medicine bottle 4 and extends into the interior. The bottom end of the drug extraction tube 6 contacts the bottom end of the interior of the medicine bottle 4. The drug extraction tube 6, the drug delivery tube 7, and the interior of the one-way valve 10 are connected. The one-way valve 10 and the interior of the hot water inlet pipe 11 are connected. The metering pump 5, the external clamp-on flow meter 8, and the PLC programmable logic controller 9 are electrically connected. The inner diameter of the external clamp-on flow meter 8 is adapted to the outer diameter of the hot water inlet pipe 11, and the drug can be automatically dispensed to improve the water quality.

[0028] Specifically, if Figure 1 and Figure 3 As shown, the external clamp-on flow meter 8 detects the flow of hot water and feeds the data back to the PLC programmable logic controller 9. The PLC programmable logic controller 9 adjusts the three groups of metering pumps 5 according to the preset instructions and the flow of hot water. The three groups of chemical bottles 4 are respectively filled with scale inhibitors, corrosion inhibitors and oxidants. The metering pumps 5 pump the chemicals through the drug extraction pipe 6 and the drug delivery pipe 7 to the one-way valve 10, and directly inject them into the hot water in the hot water inlet pipe 11, thereby ensuring the stability of water quality and improving the efficiency and service life of the chemical heat exchange equipment.

[0029] Example 2: A fixing plate 14 is fixedly connected transversely between the two sides of the interior of the air chamber 12. A plurality of metal tubes 15 are fixedly connected to the bottom end of the fixing plate 14. A plurality of blowers 16 are installed on the left side of the air chamber 12. The metal tubes 15 are arranged at equal intervals and pass through the upper and lower ends of the fixing plate 14. There is a gap between the front and rear ends of the fixing plate 14 and the front and rear ends of the interior of the air chamber 12, which can reduce water loss and improve cooling efficiency.

[0030] Specifically, if Figure 1 and Figure 2 As shown, the blower 16 blows external cold air into the air chamber 12 to cool the water mist, and the exhaust fan 13 discharges the hot and humid air in the air chamber 12. When the hot and humid air is discharged upward, it must first pass through the metal pipe 15 on the fixed plate 14. The cold metal pipe 15 extends the upward movement path of the water mist on the one hand, and at the same time allows the water vapor to condense into water droplets and drip downward, reducing water loss.

[0031] Example 3: Multiple groups of water pipes 20 are installed at the bottom end of the air chamber 12. The top of the water pipes 20 is welded with a bell mouth 21. The top of the bell mouth 21 is sleeved with a hemispherical cover 22. The bottom end of the water pipes 20 is lower than the bottom end of the air chamber 12. The interior of the hemispherical cover 22 is evenly provided with fine holes to prevent the filler from clogging the water outlet and ensure the water guiding capacity.

[0032] Specifically, if Figure 1 and Figure 4 As shown, the upwardly protruding hemispherical cover 22 can increase the contact surface with the filler, and the fine holes facilitate the infiltration of water flow, reducing the probability of blockage. The incoming water flow is guided through the bell mouth 21 and discharged downward from the water pipe 20.

[0033] Working principle: When the present invention is in use, first, the hot water returned from the heat exchange equipment enters the air chamber 12 along the hot water inlet pipe 11, and fine water mist is sprayed out from the nozzle 18 at the top of the spray pipe 17. The atomized hot water and air directly exchange heat and cool down, and flow into the water pool 1 after being filtered by the filler. When the hot water flows along the hot water inlet pipe 11, the external clamp-on flow meter 8 detects the flow rate of the hot water and feeds the data back to the PLC programmable logic controller 9. The PLC programmable logic controller 9 allocates three groups of metering pumps 5 to work according to the preset instructions and the hot water flow rate. The three groups of medicine bottles 4 are respectively filled with scale inhibitors, corrosion inhibitors and oxidants. The metering pump 5 pumps the medicine through the medicine extraction pipe 6 and the medicine delivery pipe 7 to the one-way valve 10, and directly injects it into the hot water in the hot water in the hot water inlet pipe 11, ensuring the stability of the water quality and improving the efficiency and service life of the chemical heat exchange equipment. The nozzle 18 at the top of the spray pipe 17 sprays a fine mist upward, extending the contact time between the mist and the air. The blower 16 blows cold air from the outside into the air chamber 12 to cool the mist. The exhaust fan 13 exhausts the hot and humid air in the air chamber 12. When the hot and humid air is discharged upward, it must first pass through the metal pipe 15 on the fixed plate 14. The cold metal pipe 15 not only extends the upward movement path of the mist, but also allows the water vapor to condense into water droplets and drip downward, reducing water loss. The cooled water flow seeps down along the packing layer 19. The upwardly protruding hemispherical cover 22 can increase the contact surface with the packing. The fine holes facilitate the infiltration of water flow and reduce the probability of blockage. The incoming water flow is guided through the bell mouth 21 and discharged downward from the water pipe 20.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
