Description

Technical Field

[0001] This invention relates to the field of heat exchange equipment, and in particular to a cooling water temperature control device. Background Technology

[0002] Cooling water is a key auxiliary system for ensuring the safe, efficient, and long-life operation of boilers. Its core task is to precisely control the temperature and flow rate of the cooling medium (usually water) entering each cooling part of the boiler, and to use circulating water to cool the metal to prevent overheating, excessive thermal stress, scaling, or corrosion of metal components, thus ensuring the stable operation of the boiler system.

[0003] Cooling water temperature control devices are complete sets of equipment in cooling systems. Their core function is to transfer the waste heat generated by the equipment to the environment. Common cooling water control devices are mainly water-cooled (such as cooling towers, which use water flow to remove heat) and air-cooled (such as air-cooled heat exchangers, which use flowing air to exchange and cool). These types of devices are not very efficient in utilizing the heat of cooling water waste heat. The purpose of this invention is to propose a new cooling water temperature control device to solve the above-mentioned technical problems and improve the heat utilization efficiency of cooling water. Summary of the Invention

[0004] The purpose of this invention is to provide a cooling water temperature control device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including a cooling tank, an extrusion chamber, a rotating ring, a cooling plate, a plunger, and an atomizing pump. The cooling tank is provided with an inlet and an outlet. The cooling tank is used to hold cooling water to perform cooling operations. The input and output of cooling water are realized by connecting the cooling tank to the inlet and outlet through pipes.

[0006] The extrusion chamber extends through the cooling tank, and a collection chamber is formed at the rear end of the extrusion chamber. The collection chamber is located outside the cooling tank, and a tubular drain outlet and exhaust outlet are formed on the side of the collection chamber. The drain outlet is located at the bottom to collect liquefied water, and the exhaust outlet is located on the side of the collection chamber to reduce the entry of liquefied water into the exhaust outlet. The drain outlet is used to discharge condensed cooling medium and can be connected to an air preheater or an energy saver to utilize the cooling medium carrying heat. The cooling medium refers to the medium that plays a role in cooling and heat conduction, and can be water, heat transfer oil, etc. The exhaust outlet is used to discharge pressurized gas and is connected to a vortex tube. The hot gas outlet of the vortex tube can be connected to an air preheater or an energy saver to utilize the heat carried in the hot gas and further utilize the pressurized gas through the vortex tube.

[0007] The rotating ring is set in the collection chamber and forms a rotating pair with the collection chamber. The rotating ring can block the drain port and the exhaust port, and there is a notch on the rotating ring. When the rotating ring covers the drain port and the exhaust port, the cooling medium and pressurized gas cannot leave from the drain port and the exhaust port. When the notch moves to the drain port and the exhaust port, the cooling medium and pressurized gas can leave from the drain port and the exhaust port. The rotating ring is driven by the driving device.

[0008] The cooling plate penetrates the cooling tank and is hollow with an internal cavity. One end of the cooling plate is connected to the cold air outlet of the vortex tube. After the cold air is output from the cold air outlet of the vortex tube, the cold air can move along the cavity to cool the cooling water in the cooling tank.

[0009] The plunger is located inside the extrusion chamber and forms a moving pair with the extrusion chamber along the length of the extrusion chamber. The plunger and the longitudinal cross-sectional shape of the extrusion chamber are matched. A hydraulic cylinder is provided on the side of the cooling tank and the movable end of the hydraulic cylinder is fixedly connected to the plunger.

[0010] The atomizing pump is fixed to the cooling tank, and the output pipe of the atomizing pump is connected to the extrusion chamber. The atomizing pump is used to output the cooling medium and input the cooling medium into the extrusion chamber in the form of water mist.

[0011] To optimize the above technical solution, the following measures are further taken: a first solenoid valve and a second solenoid valve are respectively installed on the drain outlet and the vent outlet. The first solenoid valve and the second solenoid valve are connected to an external controller. The purpose of this is to realize automated control of the pipes connected to the drain outlet and the vent outlet.

[0012] As a further improvement to the above technical solution: the extrusion chamber is inclined and runs through the cooling tank. The inclined extrusion chamber helps the liquefied cooling medium to flow. After the atomized cooling medium enters the extrusion chamber and completes heat exchange, it will be liquefied into a flowable liquid by the plunger. At this time, the inclined extrusion chamber structure helps the cooling medium to flow along the extrusion chamber to the collection chamber for unified collection.

[0013] As a further improvement to the technical solution: the driving device includes a magnetic gear ring and a motor. The magnetic gear ring is set on the collecting cavity and forms a rotating pair with the collecting cavity. The magnetic gear ring and the rotating ring are matched in position and attract each other. The motor is fixed to the cooling tank. The motor shaft is provided with a drive gear that meshes with the magnetic gear ring. The magnetic gear ring refers to a gear ring with magnetism. The magnetic gear ring and the rotating ring are provided with magnet blocks or use a magnetically attractive material to achieve mutual attraction between the magnetic gear ring and the rotating ring. The specific material of the magnet is not a necessary technical feature and is not the technical content that the applicant wants to protect. Therefore, it will not be further disclosed. In specific implementation, the mutual attraction between the magnetic gear ring and the rotating ring can be changed by changing the material and size of the magnet block. It should be noted that the Curie temperature of the magnet block is greater than the ambient temperature of the magnetic gear ring and the rotating ring.

[0014] As an improvement to the aforementioned technical solution: the height of the extrusion chamber and the cooling plate is lower than the water level in the cooling tank. By fully immersing the extrusion chamber and the cooling plate in the cooling water, it helps to ensure sufficient heat exchange between the cooling water and the extrusion chamber and the cooling plate.

[0015] Furthermore, the rotating ring surface is coated with a polytetrafluoroethylene (PTFE) coating. The PTFE coating has excellent chemical corrosion resistance and high temperature resistance, and its surface friction coefficient is extremely low. The purpose of this coating is to prevent scale buildup on the PTFE coating surface from affecting the rotation of the rotating ring. At the same time, the low friction coefficient helps to improve the smoothness of the rotating ring's rotation.

[0016] Furthermore, a bimetallic strip is installed inside the cavity, with its length parallel to that of the cooling plate. The bimetallic strip is a composite material composed of two metals / alloys with different coefficients of thermal expansion. Due to the difference in the coefficients of thermal expansion of the different metals, the layer with the larger coefficient of thermal expansion is called the active layer, and the layer with the smaller coefficient of thermal expansion is called the passive layer. When the temperature rises, the deformation of the active layer is greater than that of the passive layer, so the bimetallic strip will bend along the active-passive layer side, causing deformation. In specific implementations, the bending deformation capability of the bimetallic strip can be adjusted by changing its composition. The purpose of installing the bimetallic strip inside the cavity is to increase the turbulence of the cold air inside the cavity, ensuring sufficient heat exchange between the cold air and the cooling water. At low temperature / room temperature, the bimetallic strip is straight and has little impact on the cold air. When the cooling water is at a high temperature, the bimetallic strip bends and deforms, which can significantly increase the turbulence of the cold air. In specific implementations, the bimetallic strip is distributed randomly inside the cavity.

[0017] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

[0018] A. By setting up cooling plates and extrusion chambers in the cooling tank to transfer the heat of the cooling water, the cooling water can be cooled down quickly and the cooling efficiency can be easily controlled;

[0019] B. By recovering the latent heat of condensation and the hot gas output from the vortex tube, the heat transferred from the cooling water is recycled and reused, which effectively improves the heat utilization efficiency of the cooling water. Attached Figure Description

[0032] Example 1: Please refer to Figure 1-8 The present invention provides a cooling water temperature control device, including a cooling tank 100, a squeezing chamber 200, a rotating ring 300, a cooling plate 400, a plunger 500 and an atomizing pump 600, wherein the cooling tank 100 is provided with an inlet 101 and an outlet 102.

[0033] The extrusion chamber 200 extends through the cooling tank 100 at an incline. A collection chamber 201 is formed at the rear end of the extrusion chamber 200.

[0038] Example 2: Please refer to Figure 1-8 The present invention provides a cooling water temperature control device, including a cooling tank 100, a squeezing chamber 200, a rotating ring 300, a cooling plate 400, a plunger 500 and an atomizing pump 600, wherein the cooling tank 100 is provided with an inlet 101 and an outlet 102.

[0039] The extrusion chamber 200 extends through the cooling tank 100 at an incline. A collection chamber 201 is formed at the rear end of the extrusion chamber 200. The collection chamber 201 is located outside the cooling tank 100. A drain outlet 202 and an exhaust outlet 203 are formed on the side of the collection chamber 201. A first solenoid valve 205 and a second solenoid valve 206 are respectively provided on the drain outlet 202 and the exhaust outlet 203. The exhaust outlet 203 is connected to the vortex tube 204.

[0040] The rotating ring 300 is disposed in the collection chamber 201 and forms a rotating pair with the collection chamber 201. The surface of the rotating ring 300 is coated with polytetrafluoroethylene. The rotating ring 300 can block the drain outlet 202 and the exhaust outlet 203. The rotating ring 300 has a notch 301. The rotating ring 300 is driven by a driving device, which includes a magnetic gear ring 207 and a motor 208. The magnetic gear ring 207 is disposed on the collection chamber 201 and forms a rotating pair with the collection chamber 201.

The shaft of the motor 208 is provided with a drive gear 209 that meshes with the magnetic gear ring 207.

[0041] The cooling plate 400 penetrates the cooling tank 100. The height of the extrusion chamber 200 and the cooling plate 400 is lower than the cooling water level in the cooling tank 100. The cooling plate 400 is hollow and has a cavity 401 inside. One end of the cooling plate 400 is connected to the cold air outlet of the vortex tube 204. A hot bimetallic strip 402 is provided in the cavity 401. The length direction of the hot bimetallic strip 402 is parallel to the length direction of the cooling plate 400.

[0042] The plunger 500 is located inside the extrusion chamber 200 and forms a moving pair with the extrusion chamber 200 along the length direction of the extrusion chamber 200. The longitudinal cross-sectional shape of the plunger 500 matches that of the extrusion chamber 200. A hydraulic cylinder 501 is provided on the side of the cooling tank 100 and the movable end of the hydraulic cylinder 501 is fixedly connected to the plunger 500.

[0043] The atomizing pump 600 is fixed to the cooling tank 100, and the output pipe of the atomizing pump 600 is connected to the extrusion chamber 200.

[0044] Working principle: For Examples 1 and 2, the atomizing pump 600 mixes the cooling medium with air in the form of water mist and inputs it into the extrusion chamber 200. During the process, the water mist adheres to the inner wall of the extrusion chamber 200 and exchanges heat with the cooling water in the cooling tank 100 to cool the cooling water. Since the extrusion chamber 200 is inclined, the atomized droplets can move along the inclined extrusion chamber 200 to the collection chamber 201. Then, the cylinder 501 pushes the plunger 500 to move along the extrusion chamber 200. The plunger 500 can push the atomized droplets to slide off the surface of the extrusion chamber 200 and finally be collected by the collection chamber 201. During the process, the first solenoid valve 205 and the second solenoid valve 206 are closed. As the plunger 500 moves, the pressure in the extrusion chamber 200 gradually increases. The atomized droplets can liquefy in the collection chamber 201 and release heat in the form of latent heat of condensation.

[0045] Then, the rotating ring 300 rotates to match the notch 301 with the drain port 202 and block the exhaust port 203. The first solenoid valve 205 opens to release liquefied water through the drain port 202 and then closes. The discharged liquefied water carries heat and can be passed into the air preheater or energy saver for heat recovery and utilization. After the drainage action is completed, the rotating ring 300 rotates to match the notch 301 with the exhaust port 203 and block the drain port 202. At this time, the gas in the compression chamber 200 is compressed into the collection chamber 201 by the plunger 500, thus having a large pressure. The second solenoid valve 206 opens to allow the pressurized gas to be discharged from the exhaust port 203. The pressurized gas enters the vortex tube 204, and then the cold air outlet of the vortex tube 204 outputs cold air to the cavity 401. During the transportation of the cold air in the cavity 401, it exchanges heat with the cooling water through the cooling plate 400 to cool the cooling water and achieve the purpose of cooling down. The hot air output from the hot air outlet of the vortex tube 204 can be introduced into the air preheater or energy saver for secondary heat recovery and utilization. The cooling efficiency can be changed by controlling the power of the oil cylinder 501 and the atomizing pump 600. In addition, in specific implementation, it can also be combined with air-cooled and water-cooled equipment to improve the cooling efficiency of the cooling water.

[0046] The main difference between Embodiment 2 and Embodiment 1 is that a hot bimetallic strip 402 is provided in the cavity 401 of Embodiment 2. When the cooling water in the cooling tank 100 is at a low temperature or room temperature, the hot bimetallic strip 402 has little impact on the cooling air when it is in a flat state. When the cooling water is at a high temperature, the hot bimetallic strip 402 will heat up and deform, which helps to increase the turbulence of the cooling air in the cavity 401 and improve the heat exchange efficiency between the cooling air and the condensate.

[0047] In this invention, the control of each electrical component is achieved through an external controller. The controller's control circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
