Abstract
Description
Technical Field
[0001] This utility model relates to the field of condensation technology for cytosine preparation, and in particular to a condensation device for cytosine preparation. Background Technology
[0002] In today's chemical production field, cytosine is an important organic compound, and the condensation process in its preparation is crucial. The preparation of cytosine often involves complex chemical reactions, which generate a large amount of vapor. This vapor needs to be efficiently condensed and recovered to ensure product quality and yield. With the continuous development of the chemical industry, the demand for cytosine is increasing, which also puts forward higher requirements for the condensation equipment in the preparation process. Developing efficient, energy-saving and stable condensation equipment for cytosine preparation has become a problem to be solved in the industry.
[0003] Currently, in the field of cytosine preparation, traditional condensation technology mainly adopts a simple one-time cooling method. This technology introduces cooling water directly into the condensation area and uses the temperature difference between the cooling water and steam to achieve heat exchange, thereby cooling and condensing the steam. In principle, it relies solely on natural heat conduction and convection to transfer the heat of the steam to the cooling water, thus completing the condensation process. This traditional method can achieve steam cooling to a certain extent, but it has many limitations in practical applications.
[0004] However, as the cooling process continues, the cooling water absorbs heat from the steam, and its own temperature gradually rises. When the temperature difference between the cooling water and the steam narrows, the heat exchange efficiency decreases significantly, making it difficult for the subsequent steam to condense fully. This not only prolongs the entire preparation cycle but also reduces the condensation efficiency of cytosine. A large amount of uncondensed steam escapes, resulting in a decrease in product yield and affecting production efficiency. At the same time, this one-time cooling method is wasteful in terms of water resource utilization. Each cooling requires a large amount of fresh water, and the used cooling water is discharged directly without recycling or treatment, which increases production costs and puts a great deal of pressure on the environment. Therefore, a condensation device for cytosine preparation is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a condensation device for cytosine preparation, which aims to improve the problems of diminishing cooling effect and water waste in the traditional one-time cooling method in the prior art.

[0008] The circulation assembly includes a first connecting pipe, the top end of which is fixedly connected to the bottom of the inlet pipe.

The output end of the water pump is fixedly connected to the bottom end of the first connecting pipe, and the input end of the water pump is inside the water tank. A conduit is fixedly connected to one side of the water tank, and a second connecting pipe is fixedly connected to one end of the conduit.

[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, by starting the water pump, condensate is drawn from the low-level water tank, sent to the inlet pipe through connecting pipe one, and then flows into the condenser pipe. Under pressure, the condensate flows in the condenser pipe, continuously absorbing heat from the steam. After completing the heat absorption, the condensate flows out from the outlet pipe, enters connecting pipe two, and then flows back to the water tank through the conduit. This achieves the effect of condensate circulation, solves the problem of diminishing cooling effect and water waste in the traditional one-time cooling method, and improves condensation efficiency.
[0023] 2. In this utility model, when the steam pressure returns to normal, the spring, due to its own elasticity, drives the sliding column to move, which in turn drives the locking column to move horizontally, thereby causing the spring to retract and the fixing block to return to its position, so that the rubber plug is stuck in the sliding groove, achieving the effect of steam sealing. This solves the problem of product loss, environmental pollution and equipment damage caused by steam leakage, and improves the sealing performance and stability of the condensing device.

[0029] 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.
[0030] Reference Figure 1 and Figure 2This utility model provides an embodiment of a condensation device for cytosine preparation, comprising a condenser tube 1 made of glass with a spiral interior for easy transport of cytosine. This material has thermal conductivity and chemical stability, and can withstand certain temperature changes and chemical corrosion. A water outlet pipe 2 and a water inlet pipe 3 are fixedly connected to the side wall of the condenser tube 1. The water outlet pipe 2 and the water inlet pipe 3 are also made of glass, matching the material of the condenser tube 1 to ensure the sealing and stability of the connection. A flask 9 is fixedly connected to the bottom of the condenser tube 1, and an outlet is provided inside the condenser tube 1 for easy removal of the flask 9. A circulation component is provided at the bottom of the condenser tube 1 to realize the recycling of condensate and improve the efficiency of water resource utilization. A check valve component is provided at the top of the condenser tube 1 to prevent steam backflow.
[0031] The circulation assembly includes a connecting pipe 6, which is sealed with a sealing ring to prevent condensate leakage. The top of the connecting pipe 6 is fixedly connected to the bottom of the inlet pipe 3. A flask 9 is fixedly connected to the bottom of the condenser pipe 1. A water tank 4 is installed on the outer wall of the flask 9 to store condensate. The water tank 4 is made of stainless steel and has heat insulation and corrosion resistance. A water pump 5 is installed on the side wall of the water tank 4. The output end of the water pump 5 is fixedly connected to the bottom of the connecting pipe 6, and the input end of the water pump 5 is inside the water tank 4. The operation of the water pump 5 circulates the condensate from the water tank. The condensate in tank 4 is extracted and transported to inlet pipe 3 through connecting pipe 6, and then enters the condenser pipe 1. A conduit 7 is fixedly connected to one side of tank 4. The conduit 7 is made of plastic and is used to transport the condensate after heat exchange from tank 4 to connecting pipe 8. One end of the conduit 7 is fixedly connected to connecting pipe 8, which is also sealed with a sealing ring. The top of connecting pipe 8 is fixedly connected to the bottom of outlet pipe 2, so that the condensate discharged from outlet pipe 2 is transported back to tank 4, realizing the recycling of condensate.
[0032] Specifically, in the key step of cytosine preparation, cytosine vapor is continuously generated and needs to be continuously and stably absorbed to achieve condensation. At this time, water pump 5 is started to extract the condensate from the low-level water tank 4. The condensate then flows rapidly along connecting pipe 6 and is transported into the inlet pipe 3. It then enters the condenser tube 1. Under the effective pressure, the condensate flows orderly in the condenser tube 1, making full contact with the cytosine vapor and continuously absorbing a large amount of heat carried by the vapor. After completing the heat exchange, because the inside of the condenser tube 1 is spiral-shaped to increase the contact area between the condensate and the vapor, the heat exchange efficiency is improved. The vapor then begins to condense into liquid upon cooling and enters the flask 9 to complete the cooling of the cytosine. The heated condensate then flows out from the outlet pipe 2 and smoothly enters the connecting pipe 8. Subsequently, it returns to the water tank 4 through the conduit 7, achieving efficient recycling of the condensate. This not only accelerates the condensation rate of cytosine but also improves the product yield.
[0033] Reference Figure 1 and Figure 2 The check valve assembly includes a rubber plug 12 made of nitrile rubber. The rubber plug 12 ensures a good seal at the top of the condenser tube 1 and allows for flexible displacement under steam pressure. The outer wall of the rubber plug 12 is located at the top of the condenser tube 1. A feed pipe 10 is fixedly connected to the top of the condenser tube 1. A rectangular groove 11 is formed inside the feed pipe 10, and its inner wall is polished to provide a smooth channel for the sliding of the rubber plug 12 and the fixing block 13. A fixing block 13 is fixedly connected to the bottom of the rubber plug 12. The outer wall of the fixing block 13 slides in the groove 11, ensuring no shaking or jamming during sliding. The outer wall of the rubber plug 12 is slidably connected inside the groove 11, which allows the rubber plug 12 to withstand pressure. When steam pressure is applied, the device can move smoothly along the direction of the chute 11. A retaining post 14 is fixedly connected inside the feed pipe 10. The retaining post 14 is made of carbon steel and can withstand the tension and pressure of the spring 15. The spring 15 is sleeved on the outer wall of the retaining post 14. One end of the spring 15 is fixedly connected to the outer wall of the retaining post 14, and the other end of the spring 15 is fixedly connected to the bottom of the fixing block 13. A sliding post 16 is slidably connected inside the retaining post 14. The sliding post 16 is also made of aluminum alloy and its surface is lubricated to reduce friction when sliding inside the retaining post 14. The top of the sliding post 16 is fixedly connected to the bottom of the fixing block 13. When the fixing block 13 moves with the rubber plug 12, the sliding post 16 will slide synchronously inside the retaining post 14, ensuring the coordination and stability of the check valve assembly.
[0034] Specifically, when the steam in the condensing device is at risk of leakage due to various complex reasons such as sudden pressure changes or equipment failures, the steam enters from top to bottom and first impacts the rubber plug 12. The strong steam pressure pushes the rubber plug 12 to move, which in turn causes the fixing block 13 to slide smoothly inside the slide groove 11. This causes the spring 15 to be compressed, which in turn causes the locking pin 14 to move horizontally. At the same time, the sliding pin 16 inside the locking pin 14 also slides accordingly, thus opening the valve and allowing steam to enter and exit normally. When the steam pressure returns to normal or the risk of leakage is eliminated, the spring 15, with its own elasticity, causes the sliding pin 16 to move in the opposite direction, pulling the locking pin 14 to move horizontally. The spring 15 then retracts, the fixing block 13 returns to its position, and the rubber plug 12 is firmly locked inside the slide groove 11, achieving a seal, successfully preventing steam backflow, improving the sealing performance of the device, and reducing the probability of steam leakage.
[0035] Working principle: During the preparation of cytosine, it is necessary to continuously absorb the heat of cytosine vapor. At this time, water pump 5 is started to draw out the condensate from the low-level water tank 4. The condensate is then transported to the inlet pipe 3 through connecting pipe 6 and then enters the condenser pipe 1. Under pressure, the condensate flows in the condenser pipe 1, continuously absorbing the heat of cytosine vapor. The condensate then flows out from the outlet pipe 2 and enters the connecting pipe 8. Finally, it returns to the water tank 4 through the conduit 7, thus realizing the circulation of condensate and providing a more stable and efficient cooling effect, which helps to improve the condensation efficiency and yield of cytosine.
[0036] When steam leaks from the condenser due to various reasons such as pressure changes or equipment malfunctions, the steam entering from top to bottom pushes the rubber plug 12 to move, causing the fixing block 13 to slide inside the slide groove 11. This, in turn, compresses the spring 15, causing the locking pin 14 to move horizontally. This allows the sliding pin 16 inside the locking pin 14 to slide, opening the valve and allowing steam to enter and exit. Due to the elasticity of the spring 15, the sliding pin 16 is displaced, which in turn causes the locking pin 14 to move horizontally. This causes the spring 15 to retract, displacing the fixing block 13 and locking the rubber plug 12 inside the slide groove 11, achieving a seal and preventing steam backflow. This effectively enhances the sealing performance of the device and reduces the possibility of steam leakage.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
