Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a nickel heat exchange device. Background Art

[0002] Gas-liquid or liquid-liquid heat exchanger is a common heat exchange equipment, widely used in industrial production and civil fields. It is mainly used to realize heat transfer between gas, liquid and liquid, realize energy conversion and utilization, and is often used for some heat recovery and utilization or efficient and uniform temperature control heating of some liquid media. For example, in the field of optoelectronic materials and semiconductor materials, it is often necessary to accurately and uniformly heat the nickel-containing solution to 80 degrees Celsius or a specific temperature for the next process. If the temperature of the nickel-containing solution is slightly higher or lower, it may have a significant impact on the product quality. In order to meet this process requirement, liquid-liquid heat exchangers are often used to solve this problem.

[0003] Existing plate-type liquid-liquid heat exchangers are generally made of stacked metal heat conductive sheets. The metal heat conductive sheets may be provided with corrugated shapes inside to increase the contact area. The basic principle is that a fixed cavity is formed between two adjacent metal heat conductive sheets through a sealing strip, and then the gas-liquid or liquid-liquid cold and hot media are exchanged in this cavity using the excellent thermal conductivity of metal to achieve the effect of heat conversion. According to the principle of heat transfer of plate heat exchangers, in addition to the heat transfer of metal heat conductive sheets, the eddy currents and turbulences formed between each cavity of the plate heat exchanger can also increase the heat transfer. There may be some deficiencies in this explanation. First of all, the main reason for the upper and lower temperature difference of the high-temperature gas entering the cavity The metal heat conductor transfers the heat of the upper high-temperature gas to the liquid medium with lower temperature. At this time, the gas temperature in the upper layer of the cavity is lower, and the gas temperature in the lower space is higher. The temperature difference at this time leads to the formation of eddy currents and turbulences. However, the direct reason for the formation of this temperature difference is that the metal heat conductor transfers heat to the low-temperature cooling medium, which is a natural heat transfer on the metal material. The temperature difference formed has great limitations, that is, the eddy currents and turbulences formed by the cold and hot air flows in the cavity have limited effects, and the heat circulation and diffusion effect is not sufficient. That is, the thermodynamic transfer efficiency and potential of modern plate heat exchangers based on the non-hardware level have certain limitations. Based on this, a nickel heat exchange device is proposed. Utility Model Content

[0004] In order to solve the technical problem of liquid-gas heat exchanger, the utility model provides a nickel heat exchange device.

[0005] The utility model is implemented by the following technical scheme: a nickel heat exchange device, comprising a bracket, a stainless steel frame is fixedly connected to the upper side of the bracket, a nickel liquid inlet is connected to one side of the stainless steel frame, one end of the nickel liquid inlet is connected to a nickel circulation pipeline, the lower end of the nickel circulation pipeline is connected to a nickel liquid outlet passing out to the outside of the stainless steel frame, the nickel liquid outlet is located below the nickel liquid inlet, a liquid heat exchange mechanism for performing heat exchange on the nickel circulation pipeline is arranged on the lower side of the stainless steel frame, a liquid level monitoring mechanism for performing sensor monitoring of the liquid level height inside the stainless steel frame is arranged on one side of the stainless steel frame, a safety valve mechanism for maintaining the stability of the hydraulic pressure and air pressure inside the stainless steel frame is arranged on the upper side of the stainless steel frame, and a temperature sensor is arranged on the upper side of the stainless steel frame.

[0006] As a further improvement of the above scheme, the liquid heat exchange mechanism includes a liquid inlet hole and a liquid discharge hole respectively opened on the lower side of the stainless steel frame, and a spoiler fixedly connected to the inner side of the stainless steel frame is arranged above the liquid inlet hole and the liquid discharge hole, the upper side of the spoiler is fixedly connected to the lower side of the nickel circulation pipe, and an electric heating mechanism for heating the heat-conducting medium is arranged between the lower side of the spoiler and the bottom side of the stainless steel frame.

[0007] As a further improvement of the above solution, the electric heating mechanism includes a plurality of heaters arranged between the bottom of the spoiler and the bottom side of the stainless steel frame, and the plurality of heaters are fixedly connected to one side of the stainless steel frame.

[0008] As a further improvement of the above scheme, the liquid level monitoring mechanism includes a liquid level detection pipeline that simultaneously connects the upper side of the stainless steel frame and the lower side of the stainless steel frame, and the liquid level detection pipeline is respectively provided with an upper liquid level sensor, a middle liquid level sensor and a lower liquid level sensor.

[0009] As a further improvement of the above solution, the safety valve mechanism includes an upper overflow hole and an exhaust hole respectively arranged on the upper side of the stainless steel frame.

[0010] As a further improvement of the above solution, a plurality of water level floats are provided on one side of the stainless steel frame to facilitate outsiders to directly observe the water level inside the stainless steel frame.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model sets a conical threaded nickel circulation pipeline inside the stainless steel frame, and the heater heats at the bottom of the stainless steel frame. When the low-temperature nickel-containing solution enters from the nickel liquid inlet, it absorbs and takes away the heat of the surrounding liquid above the stainless steel frame and causes the temperature of the heat-conducting medium above the stainless steel frame to decrease. Due to the special structure of the conical threaded nickel circulation pipeline, the contact area between the nickel-containing solution pipeline at the lower end of the conical thread and the high-temperature liquid will gradually decrease, which directly leads to a decrease in the heat taken away by the lower liquid. In this way, from the overall point of view, the temperature of the lower liquid is high and the temperature of the upper liquid is low, thereby further expanding the temperature difference between the upper and lower liquids inside the stainless steel frame. According to the basic principle of thermal expansion and contraction, the high-temperature liquid rises rapidly, while the low-temperature liquid falls. A strong convection effect is formed in the form of turbulence and eddy current inside the liquid, which can significantly improve the heat diffusion efficiency inside the stainless steel frame and achieve a higher heating efficiency and better heat-averaging effect for the solution inside the nickel circulation pipeline.

[0013] 2. The utility model uses a liquid level monitoring mechanism and the principle of a communicating vessel to display water levels at different heights in a liquid level detection pipeline. The upper, middle and lower liquid level sensors can capture water level data information in real time and send it remotely to the purchasing office in the form of industrial communication, making the operation of the heat exchange device safer and more reliable.

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0020] Example:

[0021] Please combine Figure 1-Figure 3 A nickel heat exchange device of the present embodiment includes a bracket 1, a stainless steel frame 17 is fixedly connected to the upper side of the bracket 1, the stainless steel frame 17 is in the shape of a cube, a nickel liquid inlet 11 is connected to one side of the stainless steel frame 17, a docking valve is arranged at one end of the nickel liquid inlet 11, a nickel circulation pipeline 14 is connected to one end of the nickel circulation pipeline 11, the nickel circulation pipeline 14 is made of silicon steel, the lower end of the nickel circulation pipeline 14 is connected to a nickel liquid outlet 6 extending to the outside of the stainless steel frame 17, the nickel liquid outlet 6 is located below the nickel liquid inlet 11, a liquid heat exchange mechanism for heat exchange with the nickel circulation pipeline 14 is arranged on the lower side of the stainless steel frame 17, a liquid level monitoring mechanism for performing sensor monitoring of the liquid level height inside the stainless steel frame 17 is arranged on one side of the stainless steel frame 17, a safety valve mechanism for maintaining the stability of the hydraulic pressure and air pressure inside the stainless steel frame 17 is arranged on the upper side of the stainless steel frame 17, and a temperature sensor 16 is arranged on the upper side of the stainless steel frame 17, and the temperature data of the liquid inside the stainless steel frame 17 can be remotely obtained through the temperature sensor 16.

[0022] Please combine Figure 1 As shown, the liquid heat exchange mechanism includes a liquid inlet hole 2 and a liquid discharge hole 4 respectively opened on the lower side of the stainless steel frame 17, and a docking valve is provided at one end of the liquid inlet hole 2 and the liquid discharge hole 4, and a spoiler 3 fixedly connected to the inner side of the stainless steel frame 17 is provided above the liquid inlet hole 2 and the liquid discharge hole 4, and a plurality of irregular slots are opened on the upper side of the spoiler 3, and the upper side of the spoiler 3 is fixedly connected to the lower side of the nickel circulation pipe 14, and an electric heating mechanism for heating the heat-conducting medium is provided between the lower side of the spoiler 3 and the bottom side of the stainless steel frame 17.

[0023] Please combine Figure 1 As shown, the electric heating mechanism includes a plurality of heaters 5 arranged between the bottom of the spoiler 3 and the bottom side of the stainless steel frame 17. In this embodiment, there are two heaters 5. The specific number depends on the actual power requirement. The two heaters 5 are fixedly connected to one side of the stainless steel frame 17.

[0024] Please combine Figure 1 As shown, the liquid level monitoring mechanism includes a liquid level detection pipe 10 which connects the upper side of the stainless steel frame 17 and the lower side of the stainless steel frame 17 at the same time. The liquid level detection pipe 10 is respectively provided with an upper liquid level sensor 9, a middle liquid level sensor 8 and a lower liquid level sensor 7. It should be noted that in order to better detect the water level, the liquid level detection pipe 10 is provided with sensors at least at three heights, wherein the height of the lower liquid level sensor 7 should be consistent with the heater 5, and the upper liquid level sensor 9 should be consistent with the uppermost side of the nickel circulation pipe 14.

[0025] Please combine Figure 2As shown, the safety valve mechanism includes an upper overflow hole 13 and an exhaust hole 12 respectively arranged on the upper side of the stainless steel frame 17. When the boiling heat-conducting medium such as pure water may produce gas such as water vapor, resulting in excessive air pressure inside the stainless steel frame 17, the air pressure can be controlled within a safe and reasonable range through the exhaust hole 12. Similarly, the upper overflow hole 13 can keep the liquid hydraulic pressure inside the stainless steel frame 17 stable.

[0026] Please combine Figure 1 As shown, one side of the stainless steel frame 17 is provided with a plurality of water-adding liquid level floats 15 for outside personnel to directly observe the water level inside the stainless steel frame 17. In this embodiment, the number of the water-adding liquid level float 15 is 1. It is recommended to set a scientific number according to the height of the stainless steel frame 17, and it is recommended to set more than 3, so that it is convenient to observe the amount of water added inside the stainless steel frame 17.

[0027] The implementation principle of a nickel heat exchange device in the embodiment of the present application is as follows: a heat-conducting medium solution is injected into the stainless steel frame 17 through the liquid inlet 2 and the liquid discharge hole 4, and the heater 5 is started. The heater 5 heats the heat-conducting solution at the bottom, and the heated solution diffuses upward through the spoiler 3. When the temperature of the heat-conducting solution in the stainless steel frame 17 reaches a certain temperature as a whole, the nickel-containing solution to be heated is connected through the nickel liquid outlet 6 and the nickel liquid inlet 11. Since the nickel circulation pipe 14 is a conical threaded pipe configuration, that is, the heat absorption contact area at the upper end of the nickel circulation pipe 14 is much larger than the heat absorption contact area at the lower end, this causes the heat taken away by the upper end of the nickel circulation pipe 14 to be much larger than the heat absorption contact area at the lower end. The heat taken away by the lower end of the ring pipe 14 takes away different amounts of heat from the upper and lower layers of the stainless steel frame 17, resulting in the upper layer water temperature being significantly lower than the lower layer water temperature. This further expanded temperature difference forms a strong convection and eddy current effect inside the liquid of the stainless steel frame 17, making the heat diffusion more uniform and rapid. Through a plurality of water-adding liquid level floats 15 at different heights, the operator can judge the height of the water level inside the stainless steel frame 17 through the water-adding liquid level floats 15 from the outside. Through the upper overflow hole 13, when the amount of heat-conducting liquid is too large and exceeds the height of the upper overflow hole 13, the heat-conducting medium can be discharged from the upper overflow hole 13, thereby maintaining the internal hydraulic safety and stability of the stainless steel frame 17.

[0028] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
