DETAILED DESCRIPTION

[0026] The embodiments of the technical scheme of the utility model will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical scheme of the utility model, thus only serve as examples, and cannot limit the protection scope of the utility model. The specific structure of the utility model is shown in Figs. 1-3

[0027] Embodiment 1: an immersion longitudinal distribution graphite condenser, including bearing seat 1, a plurality of legs 2 are fixed in the bottom of the bearing seat 1, vertical cylinder 3 is fixed on the top of the bearing seat 1, main cooling cavity 4 is arranged in the inside of the vertical cylinder 3, two symmetrical immersion condensing units 5 are installed in the inside of the main cooling cavity 4, the intermediate flow guide unit 6 is connected between the two immersion condensing units 5, high-temperature air inlet pipe 7 and low-temperature liquid outlet pipe 8 are installed on the upper part and lower part of the two immersion condensing units 5 respectively, low-temperature exhaust pipe 9 is installed on the top of the intermediate flow guide unit 6, the high-temperature air inlet pipe 7 is connected with the external main gas supply pipe with pump, the low-temperature liquid outlet pipe 8 is connected with the external main liquid outlet pipe with pump, and the low-temperature exhaust pipe 9 is connected with the external main exhaust pipe with pump.

[0028] When the immersion longitudinal distribution graphite condenser is used to condense high-temperature chemical gas products, the inside of the main cooling cavity 4 is filled with cooling liquid in advance, then the external circulation pipeline and the cold source circulation pipe 10 on both sides are used to continuously transport the cold source to the inside of the auxiliary cooling cavity 11 in the two immersion condensing units 5, and the cooling liquid filled in the inside of the main cooling cavity 4 and the circulating cold source in the auxiliary cooling cavity 11 can continuously condense the high-temperature chemical gas products entering the inside of the condensing cavity 14, the high-temperature chemical gas products produce condensate products after condensation, and the remaining gas such as air is discharged outward through the low-temperature exhaust pipe 9 installed on the top of the intermediate flow guide unit 6, so that the rapid condensation of the high-temperature chemical gas products is quickly completed.

[0029] ​When the high-temperature chemical gas product is subjected to condensation treatment, external and internal cooling is simultaneously performed to improve the condensation effect, and the internal continuously circulating cold source can quickly take away heat to ensure the persistence of the condensation effect.

[0030] The two spaced immersion condensation units 5 cooperate with the middle flow guide unit 6 in the middle to quickly realize the exchange of the entering high-temperature gas in the two condensation cavities 14 in the interior, thereby improving the space heat exchange effect.

[0031] When flowing between the two condensation cavities 14, the presence of the middle flow guide unit 6 can further realize the condensation treatment.

[0032] The remaining air after the condensation treatment can be quickly discharged outward through the low-temperature exhaust pipe 9 and take away some heat to ensure the condensation effect.

[0033] On the basis of any one of the above technical solutions, the immersion condensation unit 5 further comprises a vertical heat conduction shell 12 arranged vertically, the upper and lower ends of the vertical heat conduction shell 12 are closed, a graphite cold source pipe 13 is arranged in the interior of the vertical heat conduction shell 12, the upper and lower ends of the graphite cold source pipe 13 are closed, a secondary cooling cavity 11 is arranged in the interior of the graphite cold source pipe 13, a condensation cavity 14 is arranged in the space between the graphite cold source pipe 13 and the vertical heat conduction shell 12, the inner ends of the high-temperature gas inlet pipe 7 and the low-temperature liquid outlet pipe 8 are fixed on the outer side wall of the vertical heat conduction shell 12 and are in communication with the interior of the condensation cavity 14.

[0034] The high-temperature chemical gas enters the condensation cavity 14 from the high-temperature gas inlet pipe 7, and the cold source in the secondary cooling cavity 11 in the graphite cold source pipe 13 cools it, and the condensed liquid is discharged from the low-temperature liquid outlet pipe 8. The structural design of the vertical heat conduction shell 12 and the graphite cold source pipe 13 makes the layout of the condensation cavity 14 and the secondary cooling cavity 11 reasonable, facilitating heat exchange.

[0035] On the basis of any one of the above technical solutions, the lower outer side of the vertical heat conduction shell 12 is provided with a cold source circulation pipe 10, the inner end of the cold source circulation pipe 10 extends into the condensation cavity 14 and is fixedly connected with the outer wall of the graphite cold source pipe 13, the interior of the cold source circulation pipe 10 is in communication with the interior of the secondary cooling cavity 11, and the cold source circulation pipe 10 is used in cooperation with an external circulating pipeline with a pump.

[0036] The external circulating pipeline with a pump delivers the cold source to the secondary cooling cavity 11 through the cold source circulation pipe 10 to realize the circulating flow of the cold source and continuously take away the heat in the condensation cavity 14. The arrangement of the cold source circulation pipe 10 ensures the stable supply and circulation of the cold source, thereby providing protection for continuous and efficient condensation.

[0037] Embodiment 2: Compared with Embodiment 1, the difference lies in that it further comprises the following technical features:

[0038] On the basis of any of the above technical solutions, further optimization is that the intermediate flow guide unit 6 comprises a horizontal connecting pipe 15, both ends of the horizontal connecting pipe 15 are sealingly and fixedly connected with the ports of the vertical heat conducting shell 12 at the corresponding positions, a horizontal graphite pipe 16 coaxial with the horizontal connecting pipe 15 is installed in the inside of the horizontal connecting pipe 15, both ends of the horizontal graphite pipe 16 are fixed on the outside walls of the graphite cold source pipes 13 at the corresponding positions and the insides of the two are connected in communication, a flow guide cold source channel 17 is arranged in the inside of the horizontal graphite pipe 16, both ends of the flow guide cold source channel 17 are connected in communication with the auxiliary cooling cavities 11 on both sides, and an annular channel 18 between the horizontal graphite pipe 16 and the horizontal connecting pipe 15 is used for connecting the condensing cavities 14 on both sides in communication.

[0039] The cold source from the external circulation pipeline enters the auxiliary cooling cavity 11 of the immersion condensing unit 5 through the cold source circulation pipe 10. Since both ends of the horizontal graphite pipe 16 are connected in communication with the graphite cold source pipes 13 at the corresponding positions and the flow guide cold source channel 17 in the inside is connected in communication with the auxiliary cooling cavities 11 on both sides, the cold source will circulate between the auxiliary cooling cavities 11 and the flow guide cold source channel 17. This circulation can continuously provide the intermediate flow guide unit 6 with cold energy and maintain the low-temperature environment in the inside.

[0040] The high-temperature chemical gas enters the condensing cavities 14 between the vertical heat conducting shell 12 and the graphite cold source pipes 13 through the high-temperature gas inlet pipe 7. Between the two condensing cavities 14, the gas flows through the annular channel 18 between the horizontal graphite pipe 16 and the horizontal connecting pipe 15. In the process of flowing, the high-temperature gas exchanges heat with the low-temperature environment around the annular channel 18. On the one hand, the cooling liquid in the main cooling cavity 4 outside the horizontal connecting pipe 15 absorbs part of the heat; on the other hand, the cold source circulating in the horizontal graphite pipe 16 also absorbs heat through the pipe wall, so that the high-temperature gas is continuously cooled.

[0041] When the high-temperature gas flows in the annular channel 18, the flow guide cold source channel 17 in the horizontal graphite pipe 16 performs additional condensing treatment on it. This is because the temperature of the cold source circulating in the flow guide cold source channel 17 is relatively low, and there is a large temperature difference with the high-temperature gas, which can further reduce the temperature of the gas and make it more likely to condense. In this process, part of the high-temperature gas is condensed into liquid and flows back to the bottom of the condensing cavity 14 and is discharged through the low-temperature liquid discharge pipe 8.

[0042] The intermediate flow guide unit 6 not only realizes the communication between the condensation cavities 14, but also guides the orderly flow of gas between the two condensation cavities 14. Through the design of the annular channel 18, the gas can be reasonably distributed between the two condensation cavities 14, increasing the residence time of the gas in the device and improving the heat exchange efficiency, thereby strengthening the entire condensation process and ensuring that the remaining gas is more fully treated before being discharged.

[0043] On the basis of any of the above technical solutions, further optimization is that the low-temperature exhaust pipe 9 is vertically arranged and its top is movably arranged outside the main cooling cavity 4, and the lower end of the low-temperature exhaust pipe 9 is movably arranged in the annular channel 18 and communicates with the annular channel 18.

[0044] In the annular channel 18 between the horizontal graphite pipe 16 of the intermediate flow guide unit 6 and the horizontal connecting pipe 15, the high-temperature chemical gas exchanges heat with the cold source, part of which is condensed into liquid and flows back to the bottom of the condensation cavity 14, and the remaining air and other gases are collected in the annular channel 18.

[0045] The collected remaining gas flows upward along the low-temperature exhaust pipe 9 due to its own pressure and the gas flow force in the device. Because the lower end of the low-temperature exhaust pipe 9 communicates with the annular channel 18 and the upper end movably extends outside the main cooling cavity 4, a discharge path is provided for the remaining gas. During the gas discharge process, part of the heat is also taken away, which helps to maintain the low-temperature environment inside the device and ensure the continuous and stable condensation effect.

[0046] On the basis of any of the above technical solutions, further optimization is that a cover 19 is arranged on the top of the main cooling cavity 4.

[0047] On the basis of any of the above technical solutions, further optimization is that a liquid replacement pipe joint 20 is arranged at the bottom of the vertical cylinder 3, the inside of the liquid replacement pipe joint 20 communicates with the inside of the main cooling cavity 4, and a control valve 21 is arranged on the liquid replacement pipe joint 20.

[0048] When it is necessary to replace the cooling liquid in the main cooling cavity 4, the operator opens the control valve 21 on the liquid replacement pipe joint 20. Since the main cooling cavity 4 communicates with the inside of the liquid replacement pipe joint 20, the cooling liquid in the main cooling cavity 4 will flow out through the liquid replacement pipe joint 20 under the action of gravity or external pressure (such as using a pumping device for assistance). After replacement is completed, the control valve 21 is closed to prevent the cooling liquid from continuing to flow out, maintain the sealing of the cooling liquid in the main cooling cavity 4, and enable it to normally play a cooling role.

[0049] On the basis of any of the above technical solutions, further optimization is that the two vertical heat-conducting shells 12 are fixedly arranged.

[0050] On the basis of any one of the technical solutions above, the vertical heat-conducting shell 12 is further optimized to be made of aluminum alloy material.

[0051] In the working process of the graphite condenser, the high-temperature chemical gas flows in the condensing cavity 14 between the vertical heat-conducting shell 12 and the graphite cold source pipe 13, and the vertical heat-conducting shell 12 made of aluminum alloy material can quickly transfer the heat of the high-temperature gas in the condensing cavity 14 due to its good heat-conducting performance. At the same time, the low-temperature heat of the cooling liquid in the outer main cooling cavity 4 of the vertical heat-conducting shell 12 and the cold source entering the auxiliary cooling cavity 11 through the cold source circulating pipe 10 can also be transferred to the condensing cavity 14 through the vertical heat-conducting shell 12 to exchange heat with the high-temperature gas, accelerate the condensation of the gas, and realize an efficient heat transfer process.

[0052] Specific working principle: the high-temperature chemical gas product is delivered to the immersed condensing unit 5 through the high-temperature gas inlet pipe 7 through the external pump-equipped main gas supply pipe. The main cooling cavity 4 is pre-filled with cooling liquid, and the auxiliary cooling cavity 11 of the immersed condensing unit 5 is supplied with cold source through the external circulating pipeline and the cold source circulating pipe 10, so that the high-temperature chemical gas product is condensed through the combined action of internal and external cooling.

[0053] The high-temperature chemical gas product entering the condensing cavity 14 is exchanged with the cooling liquid in the main cooling cavity 4 and the circulating cold source in the auxiliary cooling cavity 11 to be cooled and condensed, and the remaining gas is discharged through the low-temperature exhaust pipe 9. The high-temperature chemical gas product is efficiently condensed, the condensed liquid and the remaining gas are separated, and the demand for chemical gas condensation in industrial production is met.

[0054] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for part or all of the technical features; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application; any alternative improvement or change made by those skilled in the art to the embodiments of the present application falls within the protection scope of the present application.
