Description

Technical Field

[0001] The present invention relates to the technical field of temperature regulation, and particularly relates to an anodized ice-spike tube heat-melting evaporation device. Background Art

[0002] With the continuous improvement of living standards, people's demand for heating in winter and cooling in summer is increasing. Taking heating as an example, traditional heating mainly relies on fossil fuels such as coal and natural gas. When coal and natural gas burn, a large amount of black carbon and carbon dioxide are emitted. Among them, carbon dioxide releases carbonate ions and hydrogen ion condensation nuclei in water vapor, which causes the winter weather to be mild and water vapor to be excessive, affecting the diffusion of carbon microparticles into the atmosphere, forming smoggy weather, resulting in a reduction in environmental quality and affecting human survival and health.

[0003] Subsequently, as people's requirements for the ecological environment and green and low-carbon become higher and higher, a heat source tower has emerged. It adopts a low-carbon and environmentally friendly heating method that combines the absorption of low-temperature potential energy with a low-heat-source heat pump. In winter, it efficiently absorbs smog water vapor energy through phase change heat transfer with a cold aqueous solution at a small temperature difference. In summer, it has high negative-pressure evaporation, low water temperature cooling, and long-term air-conditioning waste heat refrigeration. Therefore, in winter, there is no longer a need to rely on fossil fuels such as coal and natural gas, thereby reducing the emissions of black carbon and carbon dioxide. The power consumption in summer will also decrease accordingly, reducing energy consumption, which is also beneficial to environmental protection.

[0004] The heat source tower includes an evaporation device for heat exchange. Currently, the evaporation device is provided with a pipeline, and a working medium flows in the pipeline. The working medium is a low-temperature solution, and another solution is located outside the pipeline. Still taking heating as an example, in the evaporation device, the heat in the other solution is transferred to the working medium, causing the temperature of the working medium to rise, thereby realizing the utilization of heat. However, during heat exchange, the heat will first be transferred to the side wall of the pipeline and then from the side wall of the pipeline to the other solution to achieve heat exchange between the two solutions. However, the current pipeline surface is smooth, the contact area between the pipeline and the other solution is limited, and the heating of the heat source tower mainly utilizes low-temperature potential energy. Therefore, the temperature difference between the working medium and the other solution is small. So, in the case of a limited contact area between the pipeline and the other solution, the heat transfer speed is limited, and the utilization rate of the low-temperature potential energy of the other solution is relatively low. Summary of the Invention

[0005] The present invention aims to provide an anodized ice-spike tube heat-melting evaporation device to improve the utilization rate of low-temperature potential energy.

[0006] To achieve the above object, the present invention adopts the following technical solution: an anodized ice-spike tube heat-melting evaporation device, including an ice-water side shell tube body and a working medium pipeline unit. A cavity is provided inside the ice-water side shell tube body. A cold water inlet and an ice-water outlet are provided on the side wall of the ice-water side shell tube body. The working medium pipeline unit includes an electrolytic layer ice-spike tube, and the electrolytic layer ice-spike tube is located inside the cavity. A number of protrusions are fixed on the outer wall of the electrolytic layer ice-spike tube.

[0007] The beneficial effects of this solution are as follows:

[0008] In the ice-water side shell tube of this solution, an electrolytic layer ice thorns tube is provided. Compared with the pipes in ordinary evaporation devices, due to the protrusions on the surface of the electrolytic layer ice thorns tube in this solution, when cold water with a lower temperature enters the ice-water side shell tube, the contact area with the cold water is effectively increased, so that the heat in the cold water can be quickly transferred into the working medium through the electrolytic layer ice thorns tube. During the experiment, it was found that the temperature of the cold water decreased and the enthalpy value decreased to become supercooled water after passing through the electrolytic layer ice thorns tube, indicating that the utilization rate of heat is much higher than that of the existing heat source tower, that is, this solution effectively improves the heat transfer speed and utilization rate.

[0009] Furthermore, multiple electrolytic layer ice thorns tubes are provided, and the working medium pipeline unit further includes a working medium return gas pipe and a working medium liquid distribution pipe. One ends of the multiple electrolytic layer ice thorns tubes are all connected to the working medium return gas pipe, and the other ends are connected to the working medium liquid distribution pipe.

[0010] The beneficial effects of this solution are as follows: Multiple electrolytic layer ice thorns tubes can simultaneously supply heat exchange between the working medium and the cold water, further improving the heat utilization speed.

[0011] Furthermore, multiple working medium pipeline units are provided, and the working medium return gas pipes of the multiple working medium pipeline units are connected, and the working medium liquid distribution pipes of the multiple working medium pipeline units are connected.

[0012] The beneficial effects of this solution are as follows: The electrolytic layer ice thorns tubes in multiple working medium pipelines can simultaneously supply heat exchange between the working medium and the cold water, further improving the heat utilization speed.

[0013] Furthermore, a baffle is fixed in the ice-water side shell tube. The baffle divides the inner cavity of the ice-water side shell tube into a cold water inlet shell box and an ice-water outlet shell box, and the cold water inlet shell box is communicated with the ice-water outlet shell box; the cold water inlet and the ice-water outlet are respectively communicated with the cold water inlet shell box and the ice-water outlet shell box. The working medium return gas pipe and the working medium liquid distribution pipe are respectively located in the cold water inlet shell box and the ice-water outlet shell box, and the electrolytic layer ice thorns tube penetrates through the baffle.

[0014] The beneficial effects of this solution are as follows: The baffle can block the cold water in the ice-water side shell tube, so that the cold water entering the cold water inlet shell box can form a turbulent flow, promoting the ice-water far from the electrolytic layer ice thorns tube to contact the electrolytic layer ice thorns tube; and the ice-water entering the ice-water outlet shell box from the cold water inlet shell box can also form a turbulent flow. Similarly, it can promote the ice-water to contact the electrolytic layer ice thorns tube, so that the heat in the cold water can be utilized more fully, further improving the heat utilization rate.

[0015] Furthermore, the cross-sectional area of the end of the protrusion far from the electrolytic layer ice thorns tube is smaller than the cross-sectional area of the end close to the electrolytic layer ice thorns tube.

[0016] The beneficial effects of this solution are as follows: gaps are formed between the protrusions in this solution, and the gaps are used for cold water and ice water to flow through. While further increasing the contact area with cold water and ice water, it also avoids the formation of dead ends between the protrusions that can accommodate cold water and ice water and cause the cold water and ice water to be unable to flow.

[0017] Furthermore, the cross-section of the protrusion is diamond-shaped.

[0018] The beneficial effects of this solution are as follows: when cold water and ice water pass through the electrolytic layer ice thorn tube and pass through the protrusions in this solution, turbulence can be formed, further causing the ice water far from the electrolytic layer ice thorn tube to flow towards the side close to the electrolytic layer ice thorn tube, so as to conduct heat exchange with the working medium in the electrolytic layer ice thorn tube, and further improving the utilization rate of heat.

[0019] Furthermore, a thermal resistance thawer is provided inside the ice water side shell tube body.

[0020] The beneficial effects of this solution are as follows: the evaporation device does not need to be shut down after use. At this time, if the outside temperature is too low, the liquid in the ice water side shell tube body will freeze. The thermal resistance thawer in this solution can heat the solution in the ice water side shell tube body to melt the ice, so that the evaporation device can start and work normally.

[0021] Furthermore, an ultrasonic vibrator is provided inside the cold water inlet shell box.

[0022] The beneficial effects of this solution are as follows: in this solution, the cold water forms supercooled water after passing through the electrolytic layer ice thorn tube. Under the action of the ultrasonic vibrator, ice nuclei will be generated in the supercooled water and continue to freeze, causing the enthalpy value to decrease and the temperature change to slow down. The ice nuclei crystals grow and release the heat of solidification to form vertical ice thorns on the outer wall of the electrolytic layer ice thorn tube. Since part of the supercooled water makes a direct turbulent motion on the outer wall of the electrolytic layer ice thorn tube, the growing ice thorns break off from the electrolytic layer ice thorn tube and form an ice aqueous solution with the supercooled water. Different from ordinary cold water, the ice aqueous solution can further absorb the heat in the air and thus melt to form cold water, and the cold water can be used as a heat source with low temperature potential energy and is fed into the ice water side shell tube body again to conduct heat exchange with the working medium in the electrolytic layer ice thorn tube to use the heat therein. That is, the evaporator in this solution can utilize the heat in the air by forming an ice aqueous solution, rather than being limited to using only the heat in the external water.

[0023] Secondly, the ice water needs to absorb more heat in the air before the ice in the ice water will melt, and only then will the ice water completely turn into cold water. Therefore, compared with the same amount of cold water, the ice water can absorb more heat, further improving the utilization speed and efficiency of heat.

[0024] Finally, since ice water can maintain a lower temperature for a long time, compared with cold water, the temperature difference between ice water and air is larger, and heat can be transferred to ice water faster, thereby further increasing the utilization rate of heat.

[0026] Figure 2 is Figure 1 a three-dimensional view of the electrolytic layer ice thorns tube in DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The following is a more detailed description through specific embodiments:

[0028] The reference numerals in the accompanying drawings of the specification include: working fluid inlet A, working fluid return gas port B, cold water inlet X, ice water outlet Y, working fluid distribution pipe Z, working fluid return gas pipe ZB, ice water side shell tube body ZG, electrolytic layer ice thorns tube zk, thermal resistance thawer ZR, ultrasonic oscillator ZV, baffle ZW, cold water inlet shell box ZX, and ice water outlet shell box ZY.

[0029] Embodiment

[0030] The anodized ice thorns tube thermal evaporation device is as shown in Figure 1 and Figure 2 shown. It includes an ice water side shell tube body ZG and several working fluid pipeline units. A cavity is provided inside the ice water side shell tube body ZG. A baffle ZW is vertically installed in the cavity. The baffle ZW divides the cavity into a cold water inlet shell box ZX on the left and an ice water outlet shell box ZY on the right. A gap for liquid to flow from the cold water inlet shell box ZX into the ice water outlet shell box ZY is formed between the baffle ZW and the inner wall of the ice water side shell tube body ZG. A cold water inlet X communicating with the cold water inlet shell box ZX is provided at the left end of the ice water side shell tube body ZG, and an ice water outlet Y communicating with the ice water outlet shell box ZY is provided at the right end of the ice water side shell tube body ZG. In actual implementation, pipelines are connected to both the cold water inlet X and the ice water outlet Y, respectively, for introducing cold water into the cold water inlet shell box ZX and discharging ice water from the ice water outlet shell box ZY.

[0031] A thermal resistance thawer ZR is installed in the cavity. The thermal resistance thawer ZR horizontally penetrates the baffle ZW and is used for thawing after the liquid in the cold water inlet shell box ZX and the ice water outlet shell box ZY on the right is completely frozen. An ultrasonic oscillator ZV is installed at the top of the cold water inlet shell box ZX. Specifically, both the thermal resistance thawer ZR and the ultrasonic oscillator ZV in this embodiment adopt existing equipment, and their structures and installation methods are the same as those in the prior art, so they will not be described in detail in this embodiment.

[0032] A number of working medium pipeline units are distributed in sequence from front to back. Taking one of the working medium units as an example, the working medium unit includes a working medium return air pipe ZB, a working medium liquid separation pipe Z, and a plurality of electrolytic layer ice thorn pipes zk. The working medium return air pipe ZB and the working medium liquid separation pipe Z are respectively located in the cold water inlet shell box ZX and the ice water outlet shell box ZY. The plurality of electrolytic layer ice thorn pipes zk are distributed in sequence from top to bottom. The left ends of the plurality of electrolytic layer ice thorn pipes zk are connected to the working medium return air pipe ZB, and the right ends penetrate through the baffle plate ZW and are connected to the working medium liquid separation pipe Z. All the working medium return air pipes ZB are connected, and the upper end of one of the working medium return air pipes ZB penetrates through the top of the cold water inlet shell box ZX to form a working medium return air port B. All the working medium liquid separation pipes Z are connected, and the lower end of one of the working medium liquid separation pipes Z penetrates through the bottom of the ice water outlet shell box ZY to form a working medium inlet port A.

[0033] Specifically, a number of protrusions are integrally formed on the surface of the electrolytic layer ice thorn pipe zk in this embodiment. The adjacent protrusions are arranged in a staggered manner. The cross-section of the protrusion is diamond-shaped, and the area of the cross-section of the protrusion far from the electrolytic layer ice thorn pipe zk is smaller than the area of the cross-section close to the electrolytic layer ice thorn pipe zk, so that a gap for cold water and ice water to flow through is formed between the adjacent protrusions. A number of convex ribs are arranged along the circumferential direction of the inner wall of the electrolytic layer ice thorn pipe zk. The number of convex ribs in this embodiment is spiral. In actual implementation, the convex ribs can also extend along the axial direction of the electrolytic layer ice thorn pipe zk. The convex ribs can play a role in blocking the flow of the working medium, so as to promote the working medium to form a turbulent flow during the flow process of the working medium, further promote different working media to contact the side wall of the electrolytic layer ice thorn pipe zk, and directly perform heat exchange with the side wall of the electrolytic layer ice thorn pipe zk, thereby improving the heat exchange speed.

[0034] The specific implementation process is as follows:

[0035] The working medium enters the working medium liquid separation pipe Z from the working medium inlet port A, and then enters a number of electrolytic layer ice thorn pipes zk respectively, and flows from right to left along the electrolytic layer ice thorn pipes zk. Cold water enters the cold water inlet shell box ZX from the cold water inlet X, forms a turbulent flow in the cold water inlet shell box ZX, then enters the ice water outlet shell box ZY from the cold water inlet shell box ZX, forms a turbulent flow in the ice water outlet shell box ZY, and finally discharges from the ice water outlet Y.

[0036] During the entire flow process of the cold water, the cold water comes into contact with the electrolytic layer ice pick tube zk. The heat in the cold water is finally transferred to the working fluid in the electrolytic layer ice pick tube zk, causing the working fluid to evaporate into an unsaturated gas-liquid mixture state, and finally flowing out uniformly from the working fluid return air port B; the temperature of the cold water decreases to form supercooled water. While the cold water is being introduced, the ultrasonic oscillator ZV is started. Under the action of the ultrasonic oscillator ZV, ice nuclei are formed at the tip of the protrusion far from the electrolytic layer ice pick tube zk in the supercooled water. And as time goes by, the ice nuclei crystals grow to form vertical ice picks on the outer wall of the electrolytic layer ice pick tube zk. When the length of the ice picks increases, under the action of the turbulence, the ice picks break and can flow with the supercooled water, causing the cold water to finally form an ice aqueous solution.

[0037] When the cold water in the ice water side shell tube ZG completely freezes due to too low external temperature or when the evaporation device stops operating and the cold water in the ice water side shell tube ZG completely freezes, first start the thermal resistance thawer ZR to heat the ice in the ice water side shell tube ZG to promote the melting of the ice, so as to ensure that the evaporation device can be restarted and operate normally.

[0038] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
