Description
A heat transfer medium removal pipeline device Technical Field
[0001] This utility model relates to the field of light-weight removal devices, and more specifically, to a pipeline device for removing light-weight substances from a heat medium. Background Technology
[0002] In some existing heat transfer equipment, only a heat transfer outlet pipe is installed between the heat transfer pipeline and the heat transfer storage tank. A set of branch pipes are installed on this outlet pipe to enter a cavity at the top of the heat transfer storage tank, as shown in Figure 4 of the instruction manual. Components in the heat transfer medium need to enter the heat transfer storage tank via the device. The space created by the escape of light components in the heat transfer storage tank needs to be filled with liquid phase. The gas and liquid phases flow in opposite directions here, causing the light components to mix back into the liquid heat transfer medium, increasing the light component content of the subsequent liquid heat transfer medium. This not only results in insufficient removal of light components but also causes some heat transfer medium to rise into the heat transfer storage tank during the ascent of the light components, passively altering the heat transfer medium composition and affecting the stability of the heat transfer medium supply. Therefore, a heat transfer medium light component removal pipeline device is proposed. Summary of the Invention

Detailed Implementation
[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0024] Referring to Figures 1 to 4, this embodiment of the present invention provides a pipeline device for removing light components from a heat medium, including a liquid-phase heat medium output pipeline 2, a light component removal pipeline 5, and a light component treatment device 6. The output end of the liquid-phase heat medium output pipeline 2 is connected to the light component removal pipeline 5. The light component removal pipeline 5 is a three-way pipeline. The bottom output end of the light component removal pipeline 5 is connected to the destination of the heat medium transmission, and the top output end of the light component removal pipeline 5 is sealed to the light component treatment device 6. The output end of the light component treatment device 6 is provided with a cooling conduit 7. The input end of the liquid-phase heat medium output pipeline 2 is connected to a heat medium storage tank 1, and the output end of the cooling conduit 7 is connected to the top of the inner cavity of the heat medium storage tank 1. In this solution, the light component removal pipeline 5 is provided at the output end of the heat medium storage tank 1 to remove the light component substances (low boiling point substances) carried by the liquid-phase heat medium during the output process. This avoids the light component substances from evaporating due to high temperature, which would cause pressure fluctuations in the liquid-phase heat medium in the heat medium storage tank 1, affecting its working safety. It also avoids incomplete removal of light components from the liquid-phase heat medium, which would affect its heat transfer efficiency.
[0025] This solution temporarily stores the heat medium in the heat medium storage tank 1. The liquid heat medium is discharged from the liquid heat medium output pipeline 2 to the feeding end through the valve control. During the transmission, the light components carried in the heat medium will evaporate. Before entering the feeding end, they are transferred to the light component treatment device 6 through the light component removal pipeline 5. The heat medium and light components lost in the heat medium storage tank 1 are replenished by new heat medium. The light components will not flow directly into the liquid heat medium in the heat medium storage tank 1, which would cause changes in the pressure and composition of the liquid heat medium inside the heat medium storage tank 1. The temperature inside the heat medium storage tank 1 will not be changed by the temperature carried by the light components. This can effectively ensure the stability of the pressure and temperature inside the heat medium storage tank 1.
[0026] After the light component material enters the light component processing device 6, it is heated to completely volatilize into a gaseous state. Combined with the thermal conductivity of the cooling conduit 7 itself, the gas inside the cooling conduit 7 can be gradually cooled down without liquefying it. The cooling conduit 7 guides the gas to the top of the inner cavity of the heat medium storage tank 1 for temporary storage. The gas flows from the gas pressure balance pipeline 3 into the waste discharge tank 4 and is discharged. The cavity inside the heat medium storage tank 1 where the light component is removed is filled with heat medium, which will not have a negative impact on the pressure and temperature of the liquid phase heat medium.
[0027] Referring to Figure 2, a first sealing connection seat 61 is provided at the connection between the light component processing device 6 and the light component removal pipe 5. A light component processing frame 62 is provided on the first sealing connection seat 61. The light component processing frame 62 is set as an insulation sleeve. A second sealing connection seat 66 is provided at the other end of the light component processing frame 62. A pipe connection sealing ring 67 is provided on the radially inner side of the second sealing connection seat 66. The light component processing device 6 establishes a sealed connection with the light component removal pipe 5 through the first sealing connection seat 61 and supports the setting of the light component processing frame 62. The second sealing connection seat 66 establishes a sealed connection with the cooling duct 7 through the pipe connection sealing ring 67, connecting the inner cavity of the light component processing device 6 and the inner cavity of the cooling duct 7, so as to facilitate the introduction of the light component into the cooling duct 7 after evaporation.
[0028] The first sealing connection seat 61 and the second sealing connection seat 66 are symmetrically arranged about the light component processing frame 62, which improves the uniformity of the device design and allows for quick replacement of parts when the device is damaged, thus improving the efficiency of device maintenance. The connection between the first sealing connection seat 61 and the light component removal pipe 5 is provided with an annular flow-blocking frame that is the same as the pipe connection sealing ring 67. The bottom inner side of the first sealing connection seat 61 extends inward through the annular flow-blocking frame. The through hole in the center of the annular flow-blocking frame is aligned with the feed inlet at the bottom of the feed chamber 63, and a certain flow structure is formed by utilizing the structural properties of the annular flow-blocking frame, which facilitates the concentrated flow of light components into the feed chamber 63.
[0029] Referring to Figure 3, a feeding chamber 63 is provided in the inner cavity of the light component processing rack 62 near the first sealing connection seat 61. The inlet of the feeding chamber 63 is directly opposite the light component removal pipe 5. A heating rack 64 is provided at the other end of the feeding chamber 63, and a discharge chamber 65 is provided at the other end of the heating rack 64. After the light component material enters the feeding chamber 63, it flows in its cavity. The heating rack 64 heats the light component material. Due to its low boiling point, the light component material evaporates rapidly and enters the cooling conduit 7 from the outlet of the discharge chamber 65. The cooling conduit 7 cools the light component gas to a certain extent, ensuring that the light component material is in a gaseous state and its temperature is reduced to a certain extent, so that the gas can be introduced into the heat medium storage tank 1 and then exited from the gas pressure balance pipe 3. This will not affect the pressure of the liquid phase heat medium inside the heat medium storage tank 1, ensuring normal control of the liquid phase heat medium. The airflow can carry a portion of the liquid phase heat medium in the light component back to the heat medium storage tank 1, so that the liquid phase heat medium can be separated from the light component and fall into the tank.
[0030] The discharge chamber 65 is a metal cavity with irregular walls that gradually narrows towards the gas outlet. The irregular folds increase the surface area of the outer wall of the discharge chamber 65. The outer wall structure is made of a heat-conducting material, which can increase the evaporation of light components in the heating chamber and control the gas output in conjunction with narrowing the gas outlet. The feed chamber 63 and the discharge chamber 65 are symmetrically arranged about the heating frame 64. That is, the feed chamber 63 is also a metal cavity with irregular walls that gradually narrows towards the feed inlet, which increases the surface area of the feed chamber 63 and controls the rate at which light components evaporate into the feed chamber, ensuring that all light components can be evaporated and effectively removing light components from the liquid heat medium.
[0031] The heating frame 64 is provided with a sealed heat-conducting wall on the radial inner side, and a metal heating wire cylinder is provided on the radial outer side of the sealed heat-conducting wall. The heating frame 64 uses the metal heating wire cylinder to generate heat when energized, and then uses the sealed heat-conducting wall to conduct heat, so that the heating frame 64, the feeding chamber 63 and the discharging chamber 65 are all in a high-temperature state, which facilitates the evaporation treatment of light component substances.
[0032] Referring to Figure 1, the heat medium storage tank 1 has a pressure balancing pipe 3 at one end of the cooling conduit 7. The output end of the pressure balancing pipe 3 is equipped with a waste discharge tank 4. The pressure balancing pipe 3 is set to adjust the internal pressure of the heat medium storage tank 1. During the discharge of liquid phase heat medium, the light component gas that overflows is discharged to the waste discharge tank 4 through the pressure balancing pipe 3. The waste discharge tank 4 discharges the gas in a unified manner, which facilitates the collection and use of related substances and reduces resource waste.
[0033] A pressure gauge is installed near the pressure balance pipeline 3 of the heat medium storage tank 1. The pressure gauge helps to monitor the pressure changes inside the heat medium storage tank 1 and detect whether the pressure balance pipeline 3 is working properly.
[0034] A hydraulic gauge is installed at the bottom of the heat medium storage tank 1 near the liquid phase heat medium output pipeline 2, which can detect the amount of liquid phase heat medium stored inside the heat medium storage tank 1, so as to facilitate timely replenishment of liquid phase heat medium and ensure the normal operation of the entire working system.
[0035] The present invention provides a heat medium de-lightening pipeline device, which has a liquid phase heat medium output pipeline 2 at the bottom of the heat medium storage tank 1. The liquid phase heat medium output pipeline 2 is used to provide liquid phase heat medium to the heat medium user end. During the output process, the light component substances carried by the heat medium will be separated from the liquid phase heat medium. The light component substances are received by the de-lightening pipeline 5 and quickly evaporated into gaseous substances by the heating and evaporation components in the light component processing device 6. The gaseous substances are then transported to the top of the inner cavity of the heat medium storage tank 1 through the cooling conduit 7. During this process, the gaseous substances are discharged in real time by the gas pressure balance pipeline 3, which will not affect the internal temperature of the heat medium storage tank 1, nor will it affect the change of the internal pressure of the heat medium in the heat medium storage tank 1.
[0036] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
