Description

Technical Field

[0001] This utility model relates to the technical field of cooling water, and in particular to a jacketed cooling water recycling device. Background Technology

[0002] A jacket is a sealed cavity structure that wraps around the outside of the main body of equipment (such as reactor walls, storage tanks, and pipelines). It is usually made of welded steel plates to form a channel for fluid flow. Cooling water is the heat transfer medium that flows in the jacket cavity. It is responsible for absorbing the heat generated inside the equipment and carrying it away, thereby maintaining the equipment at the required low or constant temperature.

[0003] After prolonged use, scale will form inside the jacket of the equipment. Due to the aging of the jacket or the outer wall of the main body of the equipment, some iron filings and other particles will fall into the cooling water. The cooling water in the jacket absorbs heat and has a high temperature. If this part of the cooling water is directly discharged into the sewage treatment system, it will cause a sudden change in the temperature of the sewage inlet, thereby affecting the activity of microorganisms in the sewage. Direct discharge into the environment will cause environmental pollution and waste of water resources, which has certain limitations. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a jacketed cooling water recycling device, comprising a main body, a jacket shell covering the outer wall of the main body, a connecting pipe, and a sedimentation cooler. The jacket shell and the main body form a cooling cavity. The sedimentation cooler includes a cylinder and a heat dissipation pool installed on the upper part of the cylinder. An open annular cavity is formed between the outer wall of the cylinder and the heat dissipation pool. The liquid level in the open annular cavity is lower than the top of the cylinder. One end of the connecting pipe extends into the upper part of the cooling cavity, and the other end of the connecting pipe extends into the cylinder.

[0006] Preferably, the device further includes a guide tube, a water inlet pipe, and a magnetic chuck. A mounting support is fixedly installed on the top of the heat dissipation pool. The guide tube is fixedly installed on the mounting support, with its central axis coinciding with the central axis of the cylinder body. The bottom of the guide tube extends into the cylinder body, and the top of the guide tube is higher than the top of the heat dissipation pool. One end of the water inlet pipe is connected to a connecting pipe, and the other end extends into the upper part of the guide tube. The magnetic chuck is installed inside the guide tube and located above the water inlet pipe. A sealing component is installed on the top of the guide tube. Further, the central axis of the water inlet pipe coincides with the central axis of the guide tube. The magnetic chuck can be a permanent magnet or an electromagnet. It should be noted that when an electromagnet is used, it should be waterproofed and sealed to prevent water from entering. The sealing component can be a flange blind plate or similar equivalent that seals the upper part of the guide tube.

[0007] Preferably, the sealing component includes a rotating arm, a cap, an adjusting screw, and a latch. One end of the rotating arm is hinged to a mounting support, and the other end of the rotating arm is locked to the mounting support via the latch. The adjusting screw is screwed onto the rotating arm, and the bottom of the adjusting screw is rotatably connected to the top of the cap. The cap seals the top of the guide tube, and the magnetic component is fixedly installed at the bottom of the cap. Furthermore, the cap has a sealing ring that fits into the guide tube to achieve a sealed connection between the cap and the guide tube.

[0013] Beneficial effects Compared with the prior art, this utility model provides a jacketed cooling water recycling device with the following beneficial effects: In this jacketed cooling water recycling device, the heat-absorbing cooling water in the cooling chamber is introduced into the cylinder through the connecting pipe. The cooling water overflows from the top of the cylinder into the heat dissipation pool. During the overflow process, the cooling water comes into full contact with the air, which accelerates the heat dissipation of the cooling water and increases the dissolved oxygen content in the cooling water. Meanwhile, the scale or metal particles in the cooling water settle to the bottom of the cylinder under the action of gravity. After passing through the sedimentation cooler, the cooling water temperature is reduced and can be discharged into the sewage treatment system, realizing the effective removal of particulate matter in the cooling water and effectively cooling the cooling water at the same time.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0021] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] Please refer to Figures 1-3 as well as Figure 5 A jacketed cooling water recycling device includes a main body 1, a jacket shell 2 covering the outer wall of the main body 1, a connecting pipe 3, and a sedimentation cooler. The jacket shell 2 and the main body 1 form a cooling cavity. The sedimentation cooler includes a cylinder 4 and a heat dissipation pool 5 installed on the upper part of the cylinder 4. An open annular cavity is formed between the outer wall of the cylinder 4 and the heat dissipation pool 5. The liquid level in the open annular cavity is lower than the top of the cylinder 4. One end of the connecting pipe 3 extends into the upper part of the cooling cavity, and the other end of the connecting pipe 3 extends into the cylinder 4.

[0024] Specifically, the top of the cylinder 4 is provided with multiple circumferentially distributed V-shaped grooves 21.

[0025] Please refer to Figure 3 and Figure 5 The bottom of the cylinder 4 is provided with a drain pipe 22, and a drain valve 23 is installed on the drain pipe 22; furthermore, the bottom of the cylinder 4 is conical; the conical shape of the bottom of the cylinder 4 facilitates the complete discharge of particulate sediments settled at the bottom of the cylinder 4, reducing the residue of particulate sediments in the cylinder 4.

[0026] Please refer to Figures 1-3 as well as Figure 5 The jacketed cooling water recovery and utilization device also includes a replenishment pipe 14, a spiral coil 15, and a replenishment pump 16. The spiral coil 15 is installed inside the cylinder 4. One end of the replenishment pipe 14 extends from the top of the main body 1 into the main body 1, and the other end of the replenishment pipe 14 is connected to the outlet end of the spiral coil 15. The output end of the replenishment pump 16 is connected to the inlet end of the spiral coil 15. The spiral coil 15 is preferably made of copper with good thermal conductivity.

[0027] The V-shaped groove 21 further disperses the cooling water overflowing from the cylinder 4 into the heat dissipation pool 5, increasing the contact area between the cooling water and the air, which is beneficial for heat dissipation and also increases the oxygen content in the cooling water. Opening the drain valve 23 allows the sedimented particles in the cylinder 4 to be discharged through the drain pipe 22. When liquid material needs to be replenished in the main body of the equipment 1, the liquid material is pumped into the spiral coil 15 by the replenishment pump 16. The liquid material can absorb the residual heat of the cooling water in the cylinder 4, cooling the cooling water in the cylinder 4 while raising the temperature of the liquid material entering the main body of the equipment 1. This allows the liquid material entering the main body of the equipment 1 to be preheated by the residual heat of the cooling water, making full use of the residual heat of the cooling water and avoiding excessive temperature fluctuations in the main body of the equipment due to excessively low liquid material temperature.

[0028] The jacketed cooling water recycling device also includes a guide tube 6, an inlet pipe 7, and a magnetic chuck 8. A mounting support 9 is fixedly installed on the top of the heat dissipation tank 5. The guide tube 6 is fixedly installed on the mounting support 9, with its central axis coinciding with the central axis of the cylinder 4. The bottom of the guide tube 6 extends into the cylinder 4, and the top of the guide tube 6 is higher than the top of the heat dissipation tank 5. One end of the inlet pipe 7 is connected to the connecting pipe 3, and the other end extends into the upper part of the guide tube 6. The magnetic chuck 8 is installed inside the guide tube 6 and above the inlet pipe 7. A sealing component is installed on the top of the guide tube 6. Furthermore, the central axis of the inlet pipe 7 coincides with the central axis of the guide tube 6. The magnetic chuck 8 can be a permanent magnet or an electromagnet. It should be noted that when an electromagnet is used for the magnetic chuck 8, the electromagnet should be waterproofed and sealed to prevent water from entering the electromagnet. The sealing component can be a flange blind plate or other equivalent component that seals the upper part of the guide tube 6.

[0029] The sealing component includes a rotating arm 10, a cover 11, an adjusting screw 12, and a latch 13. One end of the rotating arm 10 is hinged to the mounting support 9, and the other end of the rotating arm 10 is locked to the mounting support 9 via the latch 13. The adjusting screw 12 is screwed onto the rotating arm 10, and the bottom of the adjusting screw 12 is rotatably connected to the top of the cover 11. The cover 11 is sealed and closed onto the top of the guide tube 6, and the magnetic suction component 8 is fixedly installed at the bottom of the cover 11. Furthermore, the cover 11 is provided with a sealing ring that fits into the guide tube 6 to achieve a sealed connection between the cover 11 and the guide tube 6. A hand crank is installed on the top of the adjusting screw 12 to apply force by turning the adjusting screw 12.

[0030] Cooling water enters the upper part of the guide tube 6 through the connecting pipe 3 and the inlet pipe 7. The cooling water comes into contact with the magnetic suction component 8, which can adsorb the metal particles, mainly iron filings, in the cooling water. This captures the metal particles in the cooling water and prevents the metal particles and scale from settling into the tube 4 at the same time. There is no need to separate the scale and metal particles in the tube 4. This reduces the amount of particles settling in the tube 4 and further improves the removal effect of metal particles in the cooling water.

[0031] When it is necessary to clean metal particles on the magnetic suction assembly, the adjusting screw 12 is turned by hand crank or external tool. The adjusting screw 12 moves the cover 11 upward, and the cover 11 is disengaged from the top of the cylinder 4. The latch 13 is opened and the rotating arm 10 is rotated to 180 degrees, so that the cover 11 is placed horizontally at the mounting support 9. The operator can then clean the metal particles adsorbed by the magnetic suction part 8 on the cover 11, improving the convenience of cleaning metal particles.

[0032] The jacketed cooling water recycling device also includes an equalization tank 17, a flow pump 18, and a sewage pipe 19. The output end of the sewage pipe 19 is connected to the inside of the equalization tank 17. The inlet end of the flow pump 18 extends into the bottom of the open annular cavity, and the outlet end of the flow pump 18 extends into the sewage pipe 19.

[0033] Specifically, the sewage pipe 19 is equipped with multiple evenly distributed spiral guide vanes 20. Cooling water, cooled to below 60°C in the heat dissipation tank 5, is pumped in a metered quantity into the sewage pipe 19 by the flow pump 18. The cooling water comes into contact with the sewage entering the sewage pipe 19, and the spiral guide vanes 20 improve the mixing uniformity of the cooling water and sewage. The cooling water can then enter the regulating tank 17 to regulate the sewage temperature, maintaining the sewage temperature in the regulating tank 17 at 20-35°C. This enhances the microbial activity in subsequent sewage treatment, thereby improving the ammonia nitrogen removal efficiency of the subsequent sewage.

[0034] The process of using the jacketed cooling water recycling device provided by this utility model is as follows: The connecting pipe 3 and the inlet pipe 7 introduce the heat-absorbing cooling water in the cooling chamber into the upper part of the guide cylinder 6. The magnetic suction component 8 adsorbs the metal particles in the cooling water. Under the action of the guide cylinder 6, the cooling water flows back into the cylinder 4. The scale and other particles in the cooling water settle to the bottom of the cylinder 4. Then, the cooling water overflows into the heat dissipation pool 5 through the V-shaped toothed groove 21 at the top of the cylinder 4. During the overflow process, the cooling water comes into full contact with the air. The cooled cooling water is injected into the sewage pipe 19 by the flow pump 18. Under the action of the spiral guide vanes, the inlet temperature of the cooling water entering the regulating pool 17 is increased. The cooling water is connected to the sewage and treated by the subsequent sewage treatment equipment before being reused.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
