Description

Technical Field

[0001] This utility model relates to the field of acetylene purification technology, specifically to an acetylene purification device. Background Technology

[0002] Acetylene has a wide range of applications in the new materials industry, but the safe supply, transportation, and storage of acetylene require the use of acetone as a solvent. While this method ensures the safe flow of acetylene, it also results in acetone being transported to end-use equipment along with the acetylene during use. The acetone contained in acetylene used in the end-user market directly affects product quality, resulting in low product quality and insufficient stability. Currently, there is a lack of effective physical and chemical methods for separating acetylene and acetone. The core difficulty lies in the similarity of their properties: acetylene has a freezing point of about -78°C at room temperature and pressure, while acetone has a freezing point of about -80°C. The overlapping temperature ranges make separation extremely difficult. Excessive temperature will significantly reduce separation efficiency, while excessively low temperature will prevent separation and will also enhance the solubility of acetylene in acetone, further hindering separation. Utility Model Content

[0003] In view of the problems existing in the current acetylene purification methods, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide an acetylene purification device, which solves the problem that acetone contained in the acetylene used at the end directly affects product quality, resulting in low product quality and insufficient stability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An acetylene purification device includes an acetylene purification system and an acetylene reheating system. The acetylene purification system has two oil bath system interfaces fixed at its top, a first acetylene waste gas treatment interface fixed at one side, an acetone recovery system fixed at its bottom, a second acetylene waste gas treatment interface fixed at its top, an electric valve fixed at its top, a first liquid level detection device fixed at one end of the electric valve, and one end of the first liquid level detection device fixedly connected to the acetylene reheating system. The acetylene reheating system has an acetylene inlet fixed at its top, an acetylene supply system fixed at one side, and a third acetylene waste treatment interface and a safety valve fixed at its top.

[0006] Preferably, a pressure detector and a temperature detector are fixedly installed on the outside of the acetylene purification system and the acetylene reheating system.

[0007] Preferably, a second liquid level detection device is fixedly installed on one side of the acetone recovery system.

[0008] Preferably, a third liquid level detection device is fixedly installed between the acetylene purification system and the acetone recovery system.

[0009] Furthermore, valve bodies are fixedly installed on both of the oil bath system interfaces.

[0010] Preferably, the acetylene warming system is fixedly connected to the acetylene purification system.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention addresses the potential risks of abnormal pressure and temperature during device operation. The pressure and temperature detectors on the outside of the acetylene purification system and the reheating system, as well as the safety valve on the top of the reheating system, can monitor the pressure and temperature changes within the system in real time. When the pressure exceeds the limit, the safety valve can release pressure in time, ensuring that the system is always within the safe parameter range specified in the diagram. This avoids equipment failures or safety accidents caused by parameter malfunctions, significantly improving the stability and safety of the device operation.

[0012] This invention utilizes an acetylene purification system, combined with low-temperature purification parameters, to effectively remove impurities from acetylene. The acetylene is then cooled to the required exhaust temperature by an acetylene reheating system before being delivered to the user by an acetylene supply system. This entire process ensures both acetylene purity and a suitable output temperature, fully meeting the high-purity requirements of end-user industries and resolving the core supply contradiction in the prior art.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model discloses an acetylene purification device.

[0018] This utility model provides, for example Figure 1-2The acetylene purification device shown includes an acetylene purification system 1 and an acetylene recovery system 2. Two oil bath system interfaces 3 are fixedly installed on the top of the acetylene purification system 1. A first acetylene waste gas treatment interface 4 is fixedly installed on one side of the acetylene purification system 1. An acetone recovery system 5 is fixedly installed at the bottom of the acetylene purification system 1. A second acetylene waste gas treatment interface 6 is fixedly installed on the top of the acetone recovery system 5. An electric valve 7 is fixedly installed on the top of the acetone recovery system 5. A first liquid level detection device 8 is fixedly installed at one end of the electric valve 7. One end of the first liquid level detection device 8 is fixedly connected to the acetylene recovery system 2. The top of the acetylene recovery system 2 is fixedly... An acetylene inlet 9 is provided. An acetylene supply system 10 is fixedly installed on one side of the acetylene reheating system 2. A third acetylene waste treatment interface 11 and a safety valve 12 are fixedly installed on the top of the acetylene reheating system 2. (Given the special and dangerous nature of acetylene, all components must be explosion-proof, including but not limited to electrical appliances, distribution boxes, and components that may generate heat. They are also connected to an anti-static system and a grounding system.) The acetylene, after being reheated and regulated, is transported to the acetylene purification system 1, which is fixedly connected to the reheating system, for core purification treatment. Both oil bath system interfaces 3 on the top of the acetylene purification system 1 are equipped with valves 17 to control the flow of the oil bath medium. Connected to an external oil bath system, the oil bath medium provides a stable temperature environment for the purification system, aiding in the separation of impurities such as acetone in acetylene. Acetylene waste gas generated during purification is discharged through the first acetylene waste gas treatment port 4 on one side of the acetylene purification system 1, entering subsequent waste gas treatment stages to avoid direct emission of waste gas interfering with the purification effect. Acetone separated from acetylene during purification flows into the acetone recovery system 5 through the connection structure at the bottom of the acetylene purification system 1. During this process, the third liquid level detection device 16 between the acetylene purification system 1 and the acetone recovery system 5 monitors the liquid level at the connection point in real time to prevent acetone backflow. The second liquid level detection device 15 on one side of the recovery system 5 monitors the acetone liquid level in the recovery system. When the recovered acetone reaches the set liquid level, the electric valve 7 at the top of the acetone recovery system 5 opens. The first liquid level detection device 8 connected to one end of the electric valve 7 assists in judging the liquid level threshold, so as to realize the controllable flow or collection of acetone. At the same time, the second acetylene waste gas treatment interface 6 at the top of the acetone recovery system 5 discharges and treats the small amount of acetylene waste gas generated during the recovery process. Finally, the qualified acetylene that has been purified and separated from acetone is transported to the acetylene supply system 10 on one side of the acetylene warming system 2 after the system is circulated. The supply system provides a stable acetylene raw material to the user end.

[0019] For ease of testing, such as Figure 1 As shown, a pressure detector 13 and a temperature detector 14 are fixedly installed on the outside of the acetylene purification system 1 and the acetylene reheating system 2.

[0020] To facilitate the monitoring of the acetone recovery system level 5, such as Figure 1As shown, a second liquid level detection device 15 is fixedly installed on one side of the acetone recovery system 5.

[0021] To facilitate the detection of the liquid level in the acetylene purification system 1, such as Figure 1 As shown, a third liquid level detection device 16 is fixedly installed between the acetylene purification system 1 and the acetone recovery system 5.

[0022] Finally, for ease of control, such as Figure 1 As shown, valve bodies 17 are fixedly installed on both of the oil bath system interfaces 3, and the acetylene warming system 2 is fixedly connected to the acetylene purification system 1.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
