Description

Technical Field

[0001] This utility model relates to the field of cyclosulfonic acid production technology, specifically a condensation device. Background Technology

[0002] Cyclosulfonic acid is an important intermediate in the synthesis of cyclosulfonone, which is a highly effective herbicide for corn fields. The production of cyclosulfonic acid usually starts with 2-chloro-3-methyl-4-methylthiobenzaldehyde as the starting material, and proceeds through oxidation, alkaline hydrolysis, etherification, and finally distillation and condensation to convert the gaseous state into a liquid state.

[0003] Utility model patent application CN222187864U discloses a condensing device, including a condensing tube. The condensing tube includes a main tube and a secondary tube. One end of the main tube is connected to the gas inlet of the condensing device, and the other end is connected to a drain pipe. A first swirling device is provided inside the main tube. A first gas collecting pipe is provided at the end of the first swirling device. The inlet end of the first gas collecting pipe is connected to the main tube. The opening of the inlet end of the first gas collecting pipe faces the flow direction of the fluid in the main tube. The outlet end of the first gas collecting pipe is connected to the secondary tube, and the end of the secondary tube is connected to the drain pipe.

[0004] In the above technical solution, after the gas enters the main pipe of the condenser, the mixture of gas and liquid droplets passes through the first swirling device. Under the action of the first swirling device, the mixture of gas and liquid droplets generates swirling flow. Because the liquid has a higher density, it experiences a greater centrifugal force and requires a larger centrifugal radius. Therefore, the liquid mainly collects on the inner wall of the main pipe, forming a liquid layer, which is then discharged through the drain pipe. However, during the distillation of sulfonic acid, the gaseous temperature is high, and continuous condensation causes the temperature of the condensate and the condensation pipe to rise, affecting the continuous condensation and reducing the condensation and liquefaction effect. Utility Model Content

[0005] The purpose of this invention is to provide a condensation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A condensation device includes a condensation box, a condensation spiral tube disposed in the middle of the interior of the condensation box, an air inlet pipe extending to the outside of the condensation box at one top end of the condensation spiral tube, a liquid outlet pipe extending to the outside of the condensation box at one bottom end of the condensation spiral tube, and a conduit disposed at the center of the condensation spiral tube. A spray assembly is disposed on the top of the condensation box, and an installation groove is formed near the edge of the top of the condensation box, in which a semiconductor refrigeration chip is disposed.

[0008] The spray assembly includes a water pump and a delivery pipe connected to the output end of the water pump, and a water pumping pipe connected to the pumping end. The end of the delivery pipe extends from the outer wall of the condenser to the interior, and the end is provided with a spray pipe with several nozzles.

[0009] Furthermore, a liquid level window is provided on the outer wall of the condenser near the bottom, a drain pipe is provided on the outer wall of the condenser near the bottom, and a water inlet pipe communicating with the interior is provided on the top surface of the condenser.

[0010] In this invention, the liquid level window is made of tempered corrugated steel, which allows outsiders to easily observe the internal condensate capacity through the liquid level window. In addition, the drain pipe helps to drain and replace the internal condensate. The installation of the inlet pipe makes it convenient to add condensate to the condensation tank for cooling.

[0011] Specifically, one end of the drain pipe and the inlet pipe are welded and fixed to the condenser box, and both the drain pipe and the inlet pipe are equipped with sealing plugs. An exhaust pipe is also provided at the center of the sealing plug at the end of the inlet pipe.

[0012] In this invention, one of the sealing plugs is inserted into the drain pipe to block the drain pipe and prevent condensate from leaking out when drainage is not needed. The other sealing plug is inserted into the water inlet pipe and cooperates with the exhaust pipe. This helps to keep the internal pressure consistent with the external pressure. In addition, the small diameter of the exhaust pipe results in less condensate mist and less internal cold air being discharged, which does not affect the internal cooling and condensation process.

[0013] It should be noted that the width of the outer wall at the bottom of the thermoelectric cooler is adapted to the width of the inner wall of the mounting groove, and the bottom of the thermoelectric cooler is fixedly connected to the condenser box by screws.

[0014] In this invention, the thermoelectric cooler is composed of multiple pairs of P-type and N-type semiconductor materials connected in series to form thermocouple pairs. When a direct current passes through the thermocouples, electrons flowing from the N-type semiconductor to the P-type semiconductor absorb heat at the junction, forming a cold junction; while electrons flowing from the P-type semiconductor to the N-type semiconductor release heat at the junction, forming a hot junction. The cold junction is located inside the condenser chamber, and the hot junction is located outside the condenser chamber. The thermoelectric cooler is connected to an external power source to continuously absorb heat and cool the interior of the condenser chamber.

[0015] Furthermore, the condensing spiral tube is spiral-shaped, and the outer edge of the condensing spiral tube is tightly attached and bonded to the inner wall of the condensing box. The outer diameter of the conduit is adapted to the inner diameter of the inner side of the condensing spiral tube, and the outer wall of the conduit is tightly attached and bonded to the inner side of the condensing spiral tube. The top of the conduit is bonded to the top of the condensing box. The air inlet pipe and liquid outlet pipe are both welded to the end of the condensing spiral tube.

[0016] In this invention, the condensing spiral tube is spiral-shaped, which increases the area of ​​the condensing chamber. The contact area between the outer wall of the condensing spiral tube and the inside of the condensing box is also increased. The condensation time of the distilled high-temperature gas produced by sulfonic acid entering the condensing chamber is extended, which helps to facilitate condensation. The inlet pipe is connected to the external distilled high-temperature gas pipeline, and the outlet pipe is connected to the collection cylinder in the collection device to collect the liquefied liquid in a centralized manner.

[0017] Specifically, the bottom of the water pump is fixedly connected to the top of the condenser box by screws, the delivery end of the water pump is fixedly connected to one end of the delivery pipe by screws, and the end of the delivery pipe is welded to the spray pipe. The inside of the spray pipe and the inside of the delivery pipe are interconnected. The nozzles are distributed in a ring at equal intervals, and the inside of the nozzles is interconnected with the inside of the spray pipe.

[0018] In this invention, the water pump is connected to an external power source, the control switch is activated, and condensate is continuously delivered into the spray pipe. With the cooperation of multiple nozzles, the condensate is evenly sprayed above the condensing spiral tube, making full contact with the outer wall of the condensing spiral tube. The sprayed condensate then flows sequentially down the outer wall of the condensing spiral tube into the bottom of the condensing box.

[0019] In addition, the top of the water pump pipe is fixedly connected to the water pump end by screws. The water pump pipe is inserted into the condenser box, passes through the middle of the conduit, and extends to the bottom of the condenser box.

[0020] In this invention, with the help of the water pumping pipe, the condensate at the bottom of the condensing box is continuously drawn out and circulated for spraying. The conduit restricts the sprayed condensate from falling directly from the middle of the condensing spiral tube, reducing the contact area with the outer wall of the condensing spiral tube.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This utility model features a condenser box with a condensing spiral tube. A semiconductor cooling chip is installed at the top of the condenser box, with its cold end extending into the interior for continuous cooling. A water pump, in conjunction with a spray nozzle, sprays cooling water into the interior of the condenser box. A conduit is connected in the middle of the condensing spiral tube to guide the sprayed condensate water from the top of the condensing spiral tube downwards for cooling. High-temperature gas from the distillation of cyclosulfonic acid produced outside enters the condensing chamber inside the condensing spiral tube through the inlet pipe, and after liquefaction, it is discharged and collected through the outlet pipe.

[0023] 2. This utility model features a liquid level window for easy real-time observation of the internal condensate content, facilitating timely replenishment. With the addition of a drain pipe, it allows for convenient drainage and replacement of condensate within the condenser box. The inlet pipe facilitates the replenishment of condensate. Furthermore, a sealing plug seals the drain and inlet pipes. An exhaust pipe is attached to the sealing plug that connects to the inlet pipe, ensuring consistent pressure between the inside and outside of the condenser box and preventing large pressure differences from affecting condensation and cooling.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-5 This embodiment provides a technical solution:

[0036] A condensation device includes a condensation box 1, a liquid level window 10 is provided on the outer wall of the condensation box 1 near the bottom, a drain pipe 11 is provided on the outer wall of the condensation box 1 near the bottom, and a water inlet pipe 12 communicating with the interior is provided on the top surface of the condensation box 1.

[0037] In this invention, the liquid level window 10 is made of tempered corrugated steel, which allows outsiders to easily observe the internal condensate capacity through the liquid level window 10. With the help of the drain pipe 11, it helps to drain and replace the internal condensate. The installation of the water inlet pipe 12 makes it convenient to add the condensate needed for cooling to the condensation tank 1.

[0038] Furthermore, one end of the drain pipe 11 and the water inlet pipe 12 are welded and fixed to the condenser box 1, and both the drain pipe 11 and the water inlet pipe 12 are provided with sealing plugs 14. An exhaust pipe 140 is also provided at the center of the sealing plug 14 at the end of the water inlet pipe 12.

[0039] In this invention, one of the sealing plugs 14 is inserted into the drain pipe 11 to block the drain pipe 11 and prevent condensate from leaking out when drainage is not needed. The other sealing plug 14 is inserted into the water inlet pipe 12 and cooperates with the exhaust pipe 140. This helps to keep the internal pressure consistent with the external pressure. In addition, the exhaust pipe 140 has a small diameter, so less condensate mist is discharged and less internal cold air is discharged, which does not affect the internal cooling and condensation.

[0040] It should be noted that a condensing spiral tube 2 is provided in the middle of the condensing chamber 1. An air inlet pipe 20 extending to the outside of the condensing chamber 1 is provided at one end of the top of the condensing spiral tube 2, and a liquid outlet pipe 21 extending to the outside of the condensing chamber 1 is provided at one end of the bottom of the condensing spiral tube 2. A conduit 22 is provided at the center of the condensing spiral tube 2. The condensing spiral tube 2 is spiral-shaped, and the outer edge of the condensing spiral tube 2 is tightly attached to and bonded to the inner wall of the condensing chamber 1. The outer diameter of the conduit 22 is matched with the inner diameter of the inner side of the condensing spiral tube 2, and the outer wall of the conduit 22 is tightly attached to and bonded to the inner side of the condensing spiral tube 2. The top of the conduit 22 is bonded to the top of the condensing chamber 1. The air inlet pipe 20 and the liquid outlet pipe 21 are both welded to the end of the condensing spiral tube 2.

[0041] In this invention, the condensing spiral tube 2 is spiral-shaped, which increases the area of ​​the condensing chamber 23. The contact area between the outer wall of the condensing spiral tube 2 and the inside of the condensing box 1 is also increased. The condensation time of the distilled high-temperature gas produced by sulfonic acid entering the condensing chamber 23 is extended, which helps to facilitate condensation. The inlet pipe 20 is connected to the external distilled high-temperature gas pipeline, and the outlet pipe 21 is connected to the collection cylinder in the collection device to collect the liquefied liquid.

[0042] Furthermore, a spray assembly is provided on the top of the condenser box 1, and an installation groove 13 is provided near the edge of the top of the condenser box 1, in which a semiconductor cooling chip 4 is provided;

[0043] Secondly, the width of the outer wall of the bottom end of the thermoelectric cooler 4 is matched with the width of the inner wall of the mounting groove 13, and the bottom of the thermoelectric cooler 4 is fixedly connected to the condenser box 1 by screws.

[0044] In this invention, the thermoelectric cooler 4 is composed of multiple pairs of P-type and N-type semiconductor materials connected in series to form thermocouple pairs. When a direct current passes through the thermocouples, electrons flowing from the N-type semiconductor to the P-type semiconductor absorb heat at the junction, forming a cold junction; while electrons flowing from the P-type semiconductor to the N-type semiconductor release heat at the junction, forming a hot junction. The cold junction is located inside the condenser chamber 1, and the hot junction is located outside the condenser chamber 1. The thermoelectric cooler 4 is connected to an external power source to continuously absorb heat and cool the interior of the condenser chamber 1.

[0045] Specifically, the spray assembly includes a water pump 3 and a delivery pipe 30 connected to the output end of the water pump 3, and a water pumping pipe 31 connected to the pumping end. The end of the delivery pipe 30 extends from the outer wall of the condenser box 1 to the interior, and the end is provided with a spray pipe 32, which is provided with several nozzles 33.

[0046] It is worth adding that the bottom of the water pump 3 is fixedly connected to the top of the condenser box 1 by screws, the delivery end of the water pump 3 is fixedly connected to one end of the delivery pipe 30 by screws, and the end of the delivery pipe 30 is welded and fixed to the nozzle 32. The inside of the nozzle 32 is connected to the inside of the delivery pipe 30. The nozzles 33 are distributed in a ring at equal intervals, and the inside of the nozzles 33 is connected to the inside of the nozzle 32.

[0047] In this invention, the water pump 3 is connected to an external power source, the control switch is activated, and the condensate is continuously delivered into the spray pipe 32. With the cooperation of multiple nozzles 33, the condensate is evenly sprayed above the condensing spiral tube 2, making full contact with the outer wall of the condensing spiral tube 2. The sprayed condensate flows into the bottom of the condensing box 1 along the outer wall of the condensing spiral tube 2.

[0048] In addition, the top of the water pump pipe 31 is fixedly connected to the water pump 3 by screws. The water pump pipe 31 is inserted into the condenser box 1, passes through the middle of the conduit 22, and extends to the bottom of the condenser box 1.

[0049] In this invention, with the cooperation of the water pumping pipe 31, the condensate at the bottom of the condensing tank 1 is continuously pumped out and sprayed in a circulating manner. The conduit 22 restricts the sprayed condensate from falling directly from the middle of the condensing spiral tube 2, thereby reducing the contact area with the outer wall of the condensing spiral tube 2.

[0050] In use, the condensing device of this embodiment first fixes the semiconductor cooling chip 4 to the mounting groove 13 on the condensing box 1 with liquid level window 10 by screws. The water inlet pipe 12 and the drain pipe 11 are then combined and fixed with the condensing box 1 in sequence. One of the sealing plugs 14 is inserted and matched with the drain pipe 11, and the other sealing plug 14 with exhaust pipe 140 is inserted and matched with the water inlet pipe 12. The condensing spiral tube 2 with conduit 22 is combined and fixed with the condensing box 1. The top of the air inlet pipe 20 passes through the side wall of the top plate of the condensing box 1, and the liquid outlet pipe 21 passes through the bottom of the side wall of the condensing box 1. The water pump 3 with spray pipe 32 is fixed to the top of the condensing box 1, and the water pump pipe 31 passes through the condensing box 1 and through the conduit 22, extending to the bottom of the condensing box 1.

[0051] Then, the condensate that needs to be cooled is added to the condensing tank 1 through the inlet pipe 12. The added condensate is observed through the liquid level window 10. When the level of the condensate is close to the bottom of the condensing spiral tube 2, the addition is stopped. Then, the water pump 3 is connected to the external power supply, and the water pump pipe 31 continuously draws the condensate from the bottom of the condensing tank 1. The condensate is sprayed above the condensing spiral tube 2 through the nozzle 33. At the same time, the semiconductor cooling chip 4 is activated. The hot end dissipates heat, and the cold end extends into the interior of the condensing tank 1 to continuously absorb heat and reduce the internal temperature of the condensing tank 1. The production of cyclosulfonic acid involves oxidation reaction, alkaline reaction, and etherification reaction. Finally, the high-temperature gas distilled out is introduced into the condensing chamber 23 of the condensing spiral tube 2 through the gas inlet pipe 20. The cooled condensate continues to contact the outer wall of the condensing spiral tube 2, liquefying the high-temperature gas passing through the condensing chamber 23. The liquefied solution is discharged from the liquid outlet pipe 21 to the corresponding collection cylinder for collection.
