Description

Technical Field

[0001] This utility model relates to the field of liquid chlorine production, specifically to a condensation device used in liquid chlorine production. Background Technology

[0002] The condensation unit in liquid chlorine production is mainly used to cool gaseous chlorine and convert it into liquid chlorine. The unit usually consists of a condenser and related pipelines and a cooling medium circulation system. After gaseous chlorine enters the condenser, it exchanges heat with the cooling medium and its temperature drops below the boiling point of chlorine, thus condensing into liquid chlorine. The liquid chlorine is then collected and stored in a special container for subsequent transportation or use.

[0003] Chinese patent CN222048280U discloses a high-efficiency chlorine liquefaction device, including a chlorine liquefaction tank and a condenser. The left side of the condenser is fixedly connected to the right side of the chlorine liquefaction tank, and a pressure pump is fixedly connected to the right side of the condenser. The output end of the pressure pump is connected to the right side of the condenser. The right side of the chlorine liquefaction tank is connected to the left side of the condenser through a connecting pipe. A chlorine inlet pipe is provided on the upper surface of the chlorine liquefaction tank. This high-efficiency chlorine liquefaction device, by setting up a condenser, a chlorine inlet pipe, a temperature exchange pipe, an outlet, a baffle A, a cover plate B, and a baffle B, achieves the effect that R22 gas will not re-enter the chlorine liquefaction tank from the pressure box. After being cooled by the condenser, the R22 gas becomes R22 liquid and re-enters the chlorine liquefaction tank, resulting in higher device efficiency. This solves the problem that R22 liquid turns into gas after its temperature rises, leading to poor cooling effect on chlorine.

[0004] In the aforementioned patented high-efficiency chlorine liquefaction device, if the chlorine is not completely condensed during a single condensation process, it can only be directly discharged for subsequent treatment. There is no additional structure to further condense the residual chlorine after a single condensation, resulting in a waste of some chlorine. Utility Model Content

[0005] The purpose of this invention is to provide a condensation device for liquid chlorine production. The chlorine gas to be condensed is initially condensed after being transported through the main condenser. After condensation, a portion of the chlorine gas transported through the main condenser forms a liquid, while the gas is drawn by a liquid ring compressor and transported back to the auxiliary condenser. After being transported to the auxiliary condenser and then to the outer casing, it undergoes condensation again. The two condensation processes ensure that the chlorine gas is fully solidified, improving condensation efficiency and avoiding resource waste, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a condensation device for liquid chlorine production, comprising a shell, an auxiliary condenser tube disposed on one side inside the shell, and seven main condenser tubes evenly distributed laterally on the other side inside the shell. The main condenser tubes and the auxiliary condenser tubes are sealed and connected by a collection frame. A dividing plate is welded to one side inside the collection frame, and a second collection chamber and a first collection chamber are respectively disposed on both sides of the dividing plate. A liquid ring compressor is disposed at the upper end of the shell. The liquid ring compressor is sealed and connected to the first collection chamber through a first return pipe, and the liquid ring compressor is sealed and connected to the auxiliary condenser tube through a second return pipe. The chlorine gas that has not solidified initially can be transferred by the extraction of the liquid ring compressor, so that the chlorine gas can be transferred again and solidified.

[0007] Preferably, the lower end of the first collection chamber is provided with a first drain port, and the lower end of the second collection chamber is provided with a second drain port. The liquid chlorine that is transmitted and solidified on both sides can be discharged from the first drain port and the second drain port respectively after being diverted by the dividing plate.

[0008] Preferably, the upper end of the second collection chamber is provided with an exhaust port. After being transported and condensed by both sides, the final gas can be discharged after being transported through the exhaust port.

[0009] Preferably, the dividing plate is located between the auxiliary condenser and the main condenser, and the liquid chlorine condensed by the main condenser and the auxiliary condenser can be stored separately by dividing the tube.

[0010] Preferably, the outer walls of both the main condenser and the auxiliary condenser are provided with a first groove, which can increase the contact area between chlorine gas and the cooling liquid.

[0011] Preferably, a feed inlet is provided at the lower end of the other side of the outer casing, and a discharge outlet is provided at the upper end of the other side of the outer casing. The condensed liquid is fed into the interior of the outer casing through the feed inlet. After being heated and changing from liquid to gas, the gas is discharged from the discharge outlet. The liquid transmitted at the feed inlet is low-temperature Freon.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention features a main condenser and a secondary condenser arranged horizontally inside the outer casing. Chlorine gas awaiting condensation is initially condensed after being transported through the main condenser. After condensation, a portion of the chlorine gas forms a liquid, while the remaining gas is drawn by a liquid ring compressor and transported back to the secondary condenser. After being transported to the outer casing, it undergoes a second condensation. These two condensation processes ensure thorough solidification of the chlorine gas. The solidified liquid chlorine is then separated by a dividing plate and stored separately in the first and second collection chambers, with separate storage and discharge. Finally, any remaining gas is discharged independently from the exhaust port. This provides multiple corresponding storage locations and independent discharge points, improving condensation efficiency and preventing resource waste during the two condensation processes.

[0020] The present invention will be further described below with reference to specific embodiments.

[0021] like Figure 1 and Figure 2As shown, the condensation device for liquid chlorine production in this embodiment includes a shell 1. A secondary condenser 19 is provided on one side inside the shell 1, and seven main condenser 18 are evenly distributed laterally on the other side inside the shell 1. The main condenser 18 and the secondary condenser 19 are sealed together by a collection frame 14. The collection frame 14 is located at the lower end of the shell 1. The chlorine gas transmitted through the main condenser 18 and the secondary condenser 19 flows into the collection frame 14 after condensation.

[0022] In order to separate the liquid chlorine condensed by the main condenser 18 and the auxiliary condenser 19, a dividing plate 15 is provided on one side of the inside of the collection frame 14, and the dividing plate 15 is welded and fixed to the inner wall of the collection frame 14. The dividing plate 15 is located between the auxiliary condenser 19 and the main condenser 18, and the liquid chlorine that is transferred and condensed through the auxiliary condenser 19 and the main condenser 18 is stored separately.

[0023] The dividing plate 15 has a second collection chamber 17 and a first collection chamber 16 on its two sides respectively. The medium transmitted through the main condenser pipe 18 corresponds to the first collection chamber 16, and the medium transmitted through the second collection chamber 17 corresponds to the auxiliary condenser pipe 19.

[0024] Furthermore, in order to facilitate the transfer of chlorine gas condensed by the main condenser 18 to the interior of the auxiliary condenser 19, a liquid ring compressor 7 is provided at the upper end of the outer casing 1. The suction end of the liquid ring compressor 7 is sealed to the upper end of the first collection chamber 16 through the first return pipe 6. The liquid ring compressor 7 and the auxiliary condenser 19 are sealed to each other through the second return pipe 8. The chlorine gas extracted by the liquid ring compressor 7 can be transferred to the interior of the auxiliary condenser 19 and condensed again.

[0025] To improve the cooling efficiency of chlorine gas transfer at the main condenser 18 and auxiliary condenser 19, such as Figure 3 and Figure 5 As shown, the outer walls of the main condenser tube 18 and the auxiliary condenser tube 19 are both surrounded by a first groove 12, and a pair of second grooves 13 are recessed between two adjacent first grooves 12. The first grooves 12 and the second grooves 13 can improve the cooling efficiency of chlorine and increase the area of ​​the chlorine contact cooling position.

[0026] In order to separately discharge the liquid chlorine inside the second collection chamber 17 and the first collection chamber 16, a first drain port 4 is provided at the lower end of the first collection chamber 16, and a second drain port 5 is provided at the lower end of the second collection chamber 17. The liquid chlorine inside the second collection chamber 17 and the first collection chamber 16 can be discharged through the second drain port 5 and the first drain port 4, respectively.

[0027] Furthermore, an exhaust port 9 is provided at the upper end of the second collection chamber 17. After being transported by the auxiliary condenser pipe 19, the remaining chlorine gas is transported to the second collection chamber 17 and discharged from the exhaust port 9. The liquid chlorine condensed twice and a chlorine gas are transported and discharged independently.

[0028] A feed inlet 2 is provided at the lower end of the other side of the outer shell 1, and a discharge outlet 3 is provided at the upper end of the other side of the outer shell 1. The low-temperature R22 liquid for cooling is transferred to the interior of the outer shell 1 through the feed inlet 2. After the low-temperature R22 liquid contacts and soaks the main condenser tube 18 and the auxiliary condenser tube 19, it can complete the cooling and solidification of chlorine gas.

[0029] To ensure that chlorine gas is evenly distributed into the main condenser tube 18, a connecting frame 10 is provided at the front end of the outer wall of the outer casing 1, and the connecting frame 10 is sealed to the main condenser tube 18, such as... Figure 2 As shown, a conveying pipe 11 is provided on one side of the connecting frame 10, and the conveying pipe 11 is sealed to the connecting frame 10. After the condensed chlorine gas is transmitted through the conveying pipe 11, it is sent into the interior of the connecting frame 10 and diverted. The condenser is then transported by the main condenser pipe 18 to complete the subsequent condensation.

[0030] Working principle: When using the device and condensing chlorine gas, liquid Freon R22 is transferred to the inside of the outer casing 1 through the inlet 2, allowing the liquid R22 to contact and soak the main condenser tube 18 and the auxiliary condenser tube 19. Subsequently, after the chlorine gas is cooled and turned into liquid chlorine, the heat of the chlorine gas is transferred to the liquid R22, causing the liquid R22 to turn into gas. The gas is transferred and discharged through the outlet 3, while the chlorine gas is sent into the connecting frame 10 from the feed pipe 11. The chlorine gas is diverted and transferred through the main condenser tube 18. During the transfer process, the liquid R22 will cool down the chlorine gas in the main condenser tube 18 and condense it into liquid. The condensed liquid and some of the uncondensed chlorine gas are all transferred to the first collection chamber 16. The uncondensed gas is drawn out by the first return pipe 6 after the liquid ring compressor 7 is started. After being drawn out, the chlorine gas is transferred to the auxiliary condenser pipe 19 by the second return pipe 8. It is transferred and further condensed in the auxiliary condenser pipe 19. The condensed liquid chlorine and the uncondensed gas flow into the second collection chamber 17. The condensed liquid chlorine in the second collection chamber 17 and the first collection chamber 16 are discharged from the second drain port 5 and the first drain port 4, respectively. The uncondensed gas in the second collection chamber 17 is discharged from the exhaust port 9.
