Description

Technical Field

[0001] The present invention relates to the technical field of coolers, and in particular to a vertical water cooler. Background Art

[0002] A vertical cooler is a common industrial device, widely used in the fields of petrochemical, power, metallurgy, etc., for cooling various fluids. Traditional vertical coolers usually include a shell, a tube bundle, and a fluid distribution system. Its working principle mainly involves the heat exchange process, that is, high-temperature materials or gases come into contact with a coolant (such as air or water), and through contact heat transfer, the high-temperature materials or gases release heat to the coolant, thereby reducing the temperature.

[0003] In recent years, with the development of heat exchanger technology, different heat exchangers have emerged continuously. In production applications, heat exchange anomalies with significantly different performances are often encountered, such as long heat exchange time, poor cooling effect, etc., which bring certain adverse effects to the use process. In view of this, a vertical water cooler is specifically proposed to make up for the deficiencies in the prior art. Summary of the Invention

[0004] The purpose of the present utility model is to provide a vertical water cooler to solve the technical problems of long heat exchange time and poor cooling effect of the cooler in the prior art.

[0005] The present utility model provides a vertical water cooler, including:

[0006] An inner cylinder, the interior of the inner cylinder is hollow, and an air inlet, an air outlet, a feed inlet, and a discharge outlet are opened on the inner cylinder. The feed inlet and the discharge outlet are respectively located at the upper and lower ends of the inner cylinder, and a temperature measuring device is also fixed inside the inner cylinder;

[0007] A shell, the upper and lower ends of the shell are provided with openings and the interior is hollow. The inner cylinder is inserted into the shell. A water inlet pipe and a water outlet pipe are fixed on the side wall of the shell. A gap space for the flow of cooling water is also provided between the inner wall of the shell and the outer wall of the inner cylinder. The gap space is arranged around the inner cylinder in a surrounding manner, and the gap space is communicated with the water inlet pipe and the water outlet pipe;

[0008] Two high-temperature valves, which are respectively located at the upper and lower ends of the inner cylinder, and the high-temperature valves at the upper and lower ends of the inner cylinder are respectively fixedly connected to the air outlet and the discharge outlet.

[0009] The technical principle and beneficial effects of the present utility model are as follows:

[0010] Through the double-layer design of the inner cylinder and the outer shell, the gap space formed between the inner cylinder and the outer shell provides a flow path for the cooling water to surround the inner cylinder. This design ensures that the cooling water can contact the outer wall of the inner cylinder to the greatest extent, thereby improving the heat transfer efficiency and significantly enhancing the cooling effect. At the same time, the technical solution also has an air inlet and an air outlet on the inner cylinder, which can, while using the cooling water to cool down the inner cylinder, realize the two-way cooling of the inner cylinder by injecting cold air into the inner cylinder, maximizing the cooling speed and improving the heat exchange efficiency.

[0011] Compared with the prior art, the technical solution also has a temperature detector in the inner cylinder to monitor the temperature of the material or gas in the cylinder in real time, so that the temperature change during the cooling process can be accurately sensed. This real-time monitoring ability provides a basis for adjusting the cooling water flow rate, cooling time and operating parameters, ensuring the accuracy and controllability of the entire cooling process, avoiding the occurrence of overcooling or overheating phenomena, and enhancing the safety and reliability of the equipment operation.

[0012] In addition, high-temperature valves are provided at the upper and lower ends of the inner cylinder, which are respectively connected to the air outlet and the discharge port. The design of the high-temperature valves ensures that under high-temperature operations, the gas and materials can be effectively controlled, avoiding potential safety hazards caused by excessive temperature. Through the high-temperature valves, the internal pressure and temperature can also be flexibly adjusted to make the cooling process more stable and reduce the occurrence of accidents. At the same time, each structure provided in the technical solution is simple, without complicated disassembly and assembly, and the inlet and outlet of the materials are very convenient, enhancing the user experience.

[0013] In summary, the technical solution can not only maintain excellent cooling performance in high-temperature and high-pressure environments, but also achieve the smooth flow of materials and gases through the optimized hydrodynamic design, while providing real-time temperature monitoring and control, further enhancing the reliability of the equipment and the convenience of operation. This enables the equipment to effectively improve production efficiency, reduce energy consumption and ensure safe operation in practical applications.

[0014] Furthermore, the inner cylinder includes an upper cylinder and a lower cylinder. The upper cylinder is a hollow cylinder, and the lower cylinder is a hollow cone. The separated design of the upper cylinder and the lower cylinder in the technical solution enables the cooler to adapt to different material flow rates and pressure changes during operation. At the same time, the hollow cone structure of the lower cylinder also helps to guide the material flow, reducing the resistance and improving the uniformity of fluid distribution, thereby enhancing the cooling efficiency.

[0015] Furthermore, there are 2 temperature detectors. By setting 2 temperature detectors, the temperature in the inner cylinder can be monitored more accurately, avoiding the failure of a single temperature detector, resulting in an imbalance in the temperature measurement result and affecting the cooling effect, thereby ensuring the uniformity and stability of the cooling effect.

[0016] Furthermore, it also includes an annular plate which is arranged in the gap space, surrounds the inner cylinder, and is fixedly connected to the inner cylinder and the outer shell on both sides respectively. Water passing holes are also formed in the annular plate. The design of the annular plate in this technical solution can make the connection between the inner cylinder and the outer shell more firm. At the same time, water passing holes are formed in the annular plate, so that the cooling water can only pass through the water passing holes on the annular plate, reducing the flow rate of the cooling water in the gap space, so that the cooling water can exist in the gap space for a longer time, and further absorb heat by heat exchange with the inner cylinder, maximizing the cooling efficiency of the cooling water to the greatest extent.

[0017] Furthermore, multiple layers of annular plates are provided. By setting the multi-layer annular plate structure, the firm stability between the inner cylinder and the outer shell can be further improved, ensuring that the device can operate stably and achieve cooling. At the same time, the flow rate of the cooling water is also further reduced, maximizing the cooling efficiency.

[0018] Furthermore, the water inlet pipe is arranged at the lower end of the outer shell, and the water outlet pipe is arranged at the upper end of the outer shell. In this technical solution, the water inlet pipe is arranged at the lower end of the outer shell and the water outlet pipe is arranged at the upper end of the outer shell, ensuring that the cooling water can gradually spread from the lower end to the upper end, with better cooling effect. Compared with injecting the cooling water from the upper end to the lower end, due to the action of gravity, the cooling water will flow rapidly to the bottom of the outer shell, resulting in some cooling water being discharged from the water outlet pipe before completely absorbing the heat in the inner cylinder, thus wasting water resources.

[0019] Furthermore, the air inlet is arranged at the lower end of the inner cylinder, and the air outlet is arranged at the upper end of the inner cylinder. Since hot air tends to move upward, arranging the air outlet at the upper end of the inner cylinder and the air inlet at the lower end of the inner cylinder can help the hot air quickly discharge from the inner cylinder, thus improving the cooling efficiency.

[0020] Furthermore, the outer shell and the high-temperature valve are made of high-temperature resistant metal materials. Making the outer shell and the high-temperature valve of high-temperature resistant metal materials enhances the stability and durability of the cooler in a high-temperature environment, ensuring the reliability of the equipment during long-term operation.

[0021] Furthermore, the inner cylinder is made of nickel-based alloy material or nickel-chromium alloy. Making the inner cylinder of nickel-based alloy material or nickel-chromium alloy enhances the corrosion resistance and high-temperature resistance of the inner cylinder, extends the service life of the equipment, and ensures the structural stability under high temperature and high pressure.

[0028] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

Embodiment

[0030] This embodiment provides a vertical water cooler, as shown in the attached Figure 1 、the attached Figure 2 and the attached Figure 3As shown in the figure, it includes three main parts: an inner cylinder 1, an outer shell 2, and a high-temperature valve 3. The inner cylinder 1 is hollow inside and is vertically arranged with the placement point of the cooler as the horizontal line. Its outer contour is a cylinder, and its interior is mainly used to store high-temperature materials that need to be cooled. A temperature detector 15 (such as a thermocouple temperature detector 15) is also fixed inside the inner cylinder 1. In this embodiment, 2 temperature detectors 15 are provided. Of course, according to the size of the inner cylinder 1 and the requirements of the scenario, other numbers of temperature detectors 15 can be set, which will not be elaborated here. The temperature detector 15 is used to measure the real-time temperature inside the inner cylinder 1. When the temperature inside the inner cylinder 1 has dropped to the temperature expected by the user, the user can take out the cooled material in the inner cylinder 1.

[0031] In this embodiment, the inner cylinder 1 is made of nickel-based alloy material or nickel-chromium alloy, so that the inner cylinder 1 has good corrosion resistance and high-temperature resistance, thereby extending the service life of the cooler. The inner cylinder 1 includes an upper cylinder and a lower cylinder. The upper cylinder is a hollow cylinder, and the lower cylinder is a hollow cone. The inner cylinder 1 is designed as an upper cylinder and a lower cylinder, so that the upper cylinder can store high-temperature materials for cooling treatment to the maximum extent at one time, and the conical structure of the lower cylinder helps to guide the cooled material to flow towards the discharge port 14 in the inner cylinder 1, reducing the flow resistance.

[0032] In this embodiment, a feed port 12 and an air outlet 13 are also provided on the upper cylinder, and a discharge port 14 and an air inlet 11 are provided on the lower cylinder. The feed port 12 is used to introduce high-temperature materials into the inner cylinder 1, and the discharge port 14 is used to timely discharge the cooled materials from the inner cylinder 1. When it is necessary to cool the high-temperature materials in the inner cylinder 1, the cooling gas is introduced from the air inlet 11 on the lower cylinder. After the cooling gas enters the inner cylinder 1, it moves from the lower cylinder towards the upper cylinder, thereby absorbing the heat in the inner cylinder 1 and discharging it from the air outlet 13 in the upper cylinder, so as to realize the cooling of the materials in the inner cylinder 1. Since the cooling gas becomes hot air after absorbing heat, the molecular movement between hot air is more intense and more inclined to move upward. Therefore, the air outlet 13 is arranged on the upper cylinder and the air inlet 11 is arranged on the lower cylinder, which helps the hot air to quickly discharge from the inner cylinder 1, thereby improving the cooling efficiency.

[0033] The housing 2 in this embodiment includes an upper housing and a lower housing. The upper housing is a hollow cylinder, and the lower housing is a hollow frustum of a cone. The upper housing and the lower housing are detachably connected, which is convenient for installation and maintenance. The lower cylinder in the inner cylinder 1 is inserted into the lower housing, and the upper cylinder is inserted into the upper housing, thus forming a complete cooling circulation system. A gap space 4 for the flow of cooling water is also provided between the inner wall of the housing 2 and the outer wall of the inner cylinder 1. The gap space 4 is arranged around the inner cylinder 1. A ring plate 41 is also provided in the gap space 4. Both ends of the ring plate 41 are welded and fixed to the outer wall of the inner cylinder 1 and the inner wall of the housing 2 respectively, so that the connection between the inner cylinder 1 and the housing 2 is more firm. In this embodiment, the ring plate 41 is provided with 4 layers in the gap space 4. The ring plate 41 is also provided with water passing holes 411. The water passing holes 411 are mainly used for the cooling water to pass through the ring plate 41. In this embodiment, 4 water passing holes 411 are also provided. The above-mentioned ring plate 41 and water passing holes 411 can be adjusted appropriately according to other scenarios and will not be elaborated in this embodiment.

[0034] An inlet pipe and an outlet pipe are also fixed on the housing 2 in this embodiment. The inlet pipe is located on the lower housing, and the outlet pipe is located on the upper housing. Both the inlet pipe and the outlet pipe are communicated with the above-mentioned gap space 4, so that the cooling water can enter the gap space 4 from the inlet pipe, absorb heat, and then be discharged from the outlet pipe, thus achieving the cooling effect.

[0035] A high-temperature valve 3 is also provided in this embodiment. There are 2 high-temperature valves 3 respectively located at the upper and lower ends of the inner cylinder 1. The high-temperature valve 3 at the upper end is fixed above the upper cylinder and is fixedly connected to the air outlet 13 on the upper cylinder. The high-temperature valve 3 at the lower end is located below the lower cylinder and is fixedly connected to the discharge port 14 on the lower cylinder. The design of the high-temperature valve 3 ensures that under high-temperature operation, gases and materials can be effectively controlled and discharged from the inner cylinder 1 in a timely manner, avoiding potential safety hazards caused by excessive temperature. Through the high-temperature valve 3, the internal pressure and temperature can also be flexibly adjusted, making the cooling process more stable and reducing the occurrence of accidents.

[0036] The above-mentioned high-temperature valve 3 and housing 2 are made of high-temperature resistant metal materials. In this embodiment, 630-type stainless steel materials can be used. The housing 2 and high-temperature valve 3 made of stainless steel materials enhance the stability and durability of the cooler in a high-temperature environment and ensure the reliability of the equipment during long-term operation.

[0037] Specific usage process: For this vertical water cooler, during specific operation, first, a material loading process is carried out, that is, the high-temperature material to be cooled is loaded into the inner cylinder 1 through the feed port 12 opened on the inner cylinder 1. Since the high-temperature valves 3 above and below the inner cylinder 1 are in a tightened state at this time, the material in the inner cylinder 1 is in a relatively isolated state. Secondly, a material cooling process is carried out, that is, cold air is introduced into the inner cylinder 1 (by introducing cold air into the air inlet 11 and discharging hot air from the air outlet 13) and cooling water is added to the gap space 4 between the inner cylinder 1 and the outer shell 2 (by introducing cooling water into the water inlet 21 and discharging hot water from the water outlet 22). The cold air and cooling water do not directly contact the high-temperature material, but absorb the high temperature emitted by the material in the inner cylinder 1 through heat conduction, thereby cooling the material. When the temperature detector 15 in the inner cylinder 1 detects that the temperature in the inner cylinder 1 reaches a certain temperature threshold, the user only needs to unscrew the high-temperature valve 3 located below the inner cylinder 1 at this time. At this time, the cooled material will flow out from the discharge port 14 of the inner cylinder 1, and finally the cooling of the material is completed. Embodiment

[0038] The difference between this embodiment and Embodiment 1 is that, as shown in the attached Figure 4 and the attached Figure 5 As shown, a medicine storage box 6 is also fixed on one outer side of the above-mentioned outer shell 2. This medicine storage box 6 is used to store powder particles (such as baking soda). The powder particles can chemically react with other impurities such as water scale to remove the water scale. The inside of the medicine storage box 6 is hollow, and a partition 62 is also provided inside the medicine storage box 6. The upper and lower ends of the partition 62 are slidably connected to the inner wall of the medicine storage box 6. The partition 62 divides the internal space of the medicine storage box 6 into a first cavity 65 and a second cavity 66. The first cavity 65 is used to store powder particles, while the second cavity 66 is used to place the cylinder 64. Among them, one inner side wall of the first cavity 65 and the outer side wall of the outer shell 2 are the same side wall and share the same wall, thus forming a closed cuboid-shaped chamber.

[0039] An adding medicine port 61 is also opened above the above-mentioned first cavity 65. This adding medicine port 61 is used for the user to timely supplement the powder particles into the first cavity 65 to avoid insufficient powder particles in the first cavity 65, thereby affecting the removal of water scale. In addition, a powder particle inlet is also opened on the inner side wall of the first cavity 65 in this embodiment (that is, this inner side wall is the outer side wall shared with the outer shell 2), and a pressure valve 63 is fixed at the powder particle inlet. When the pressure in the first cavity 65 increases, the pressure valve 63 will open, so that the powder particles enter the gap space 4 formed between the outer shell 2 and the inner cylinder 1 (that is, the flow path of the cooling water) through the above-mentioned powder particle opening.

[0040] The above-mentioned second cavity 66 is formed by the inner side wall of the medicine storage box 6 and the partition plate 62 together. The chamber structure of the second cavity 66 is also in the shape of a cuboid. The cylinder 64 placed in the second cavity 66 is detachably connected to the side wall in the second cavity 66, which is convenient for timely repair and replacement of the cylinder 64. At the same time, the piston of the cylinder 64 is fixedly connected to the partition plate 62. When the piston of the cylinder 64 moves forward, since the piston is fixedly connected to the partition plate 62, the partition plate 62 located in the medicine storage box 6 slides relative to the inner wall of the medicine storage box 6.

[0041] In this embodiment, there are also a controller 5, a water flow sensor, and an alarm 7. The controller 5 is fixed on the side wall of the outer shell 2, and the water flow sensor is fixed in the gap space 4 between the outer wall of the inner cylinder 1 and the inner wall of the outer shell 2. At the same time, the controller 5, the water flow sensor, the alarm 7, and the above-mentioned cylinder 64 are electrically connected. The controller 5 in this embodiment selects a single-chip microcomputer for control, the water flow sensor selects a small Hall water flow sensor, and the alarm 7 selects a warning light. In other scenarios, a buzzer can also be selected for setting.

[0042] When the vertical water cooler in this embodiment is specifically used, part of the use process is the same as that in Embodiment 1. However, this embodiment can additionally monitor the water flow in the above-mentioned gap space 4 and perform intervention processing to avoid a reduction in the cooling effect. That is, in this embodiment, the water flow sensor arranged in the gap space 4 is used to detect the information of the water flow situation flowing in the gap space 4 in real time and send it to the controller 5, and the controller 5 performs further intelligent control to remove the scale in the gap space 4 and improve the cooling effect.

[0043] The specific scale removal process is as follows: When the cooler uses cooling water and cooling gas to cool the inner cylinder 1 in a double cycle, if the water flow sensor detects that the water flow signal in the gap space 4 decreases within a certain period of time, it indicates that in the gap space 4 at this time, there may be impurity particles in the cooling water forming scale, which causes partial blockage of the gap space 4, resulting in a decrease in the water flow rate of the cooling water, and ultimately further reducing the cooling efficiency of the cooler. At this time, the controller 5 will control the cylinder 64 in the medicine storage box 6 to push its piston, so that the partition plate 62 moves. Since the space in the first cavity 65 starts to become smaller, the pressure increases, and the pressure valve 63 on one side wall of the first cavity 65 (the same side wall as the outer side wall of the outer shell 2) will open, so that the powder particles in the first cavity 65 can successfully enter the gap space 4 through the powder particle inlet. Through the gradual transportation of the cooling water, they reach the corresponding scale area, and the powder particles react chemically with the scale, thereby completing the removal of the scale to further improve the cooling efficiency.

[0044] During the process of removing scale as described above in this embodiment, if after the piston in the cylinder 64 moves for a period of time, the water flow size signal detected by the water flow sensor does not increase further. It indicates that the content of the powder particles in the first cavity 65 is insufficient and cannot completely remove other impurities such as scale in the clearance space 4. At this time, the controller 5 will control the alarm 7 to issue an alarm, reminding the user to supplement the powder particles in time from the medicine opening to continue the removal of scale.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
