Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of fluorination reaction equipment, specifically referring to a gas leakage monitoring and alarm device for a fluorination reactor. Background Technology
[0002] Fluorination requires hydrogen fluoride to react with hydrocarbons. Fluorination reactions are usually carried out at high temperatures, are vigorous and fast, and involve large heat changes that are difficult to control. Diluents such as nitrogen must be used to dilute the reactants. Hydrogen fluoride is a colorless, toxic gas with an irritating odor at room temperature and pressure. It is highly hygroscopic and corrosive. When exposed to air, it easily combines with water vapor to produce white mist, causing pollution.
[0003] However, most existing gas leak monitoring and alarm devices for fluorination reactors install the monitoring device on the outside of the fluorination reactor. Since the density of hydrogen fluoride is greater than that of control air, when a leak occurs, the hydrogen fluoride flows downward and accumulates on the ground, causing a delay in leak monitoring and alarm, which affects environmental safety. Utility Model Content
[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this utility model proposes a gas leak monitoring and alarm device for a fluorination reactor. This device effectively solves the problem that most gas leak monitoring and alarm devices for fluorination reactors install the monitoring device on the outside of the fluorination reactor. Since the density of hydrogen fluoride is greater than that of control air, when a leak occurs, the hydrogen fluoride flows downward and accumulates on the ground, causing a delay in leak monitoring and alarm, which affects environmental safety.
[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a gas leakage monitoring and alarm device for a fluorination reactor, including a blower, a high-efficiency collection structure, and a monitoring and alarm structure. The high-efficiency collection structure is installed on the blower, and the monitoring and alarm structure is installed on the blower. The high-efficiency collection structure includes a suction pipe, a base, an annular pipe, and an air inlet. The suction pipe is connected to the air inlet of the blower. The base is fixed below the suction pipe. The annular pipe is installed below the base and connected to the suction pipe. The air inlet is horizontally installed through the bottom of the annular pipe.
[0006] Preferably, the monitoring and alarm structure includes an exhaust pipe, a reaction chamber, a hydrogen fluoride gas detector, a highly sensitive sensor head, a conductive wire, and an alarm. The exhaust pipe is connected to the exhaust port of the blower, the reaction chamber is connected to the top of the exhaust pipe, the hydrogen fluoride gas detector is fixedly installed above the reaction chamber, the highly sensitive sensor head passes through the reaction chamber, one end is electrically connected to the hydrogen fluoride gas detector, and the other end is installed inside the reaction chamber. One end of the conductive wire is electrically connected to the hydrogen fluoride gas detector, and the alarm is electrically connected to the other end of the conductive wire.
[0007] To achieve better monitoring results, the hydrogen fluoride gas detector is equipped with existing mature technology equipment, model LB-MD suction tube X.
[0008] To achieve more rapid and sensitive monitoring, the high-sensitivity sensor head is made of copper.
[0009] Furthermore, the annular tube is arranged in a circular shape.
[0010] To achieve the effect of bottom suction, the air inlet is conveniently located on the tangent plane at the bottom of the annular tube.
[0011] The beneficial effects of this utility model using the above structure are as follows: The gas leakage monitoring and alarm device for a fluorination reactor proposed in this solution has an air inlet at the bottom of the annular pipe, which immediately draws in the leaked hydrogen fluoride and discharges it into the reaction chamber through the exhaust pipe. There, it undergoes an electrochemical reaction with the high-sensitivity sensor head, generating current and thus issuing an alarm signal, achieving efficient triggering of the alarm.

[0016] The accompanying drawings are provided to further understand the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation thereof. Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0018] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention proposes a gas leak monitoring and alarm device for a fluorination reactor, comprising a blower 1, a high-efficiency collection structure 2, and a monitoring and alarm structure 3. The high-efficiency collection structure 2 is mounted on the blower 1, and the monitoring and alarm structure 3 is mounted on the blower 1. The high-efficiency collection structure 2 includes a suction pipe 4, a base 5, an annular pipe 7, and an air inlet 8. The suction pipe 4 is connected to the air inlet 8 of the blower 1. The base 5 is fixed below the suction pipe 4. The annular pipe 7 is mounted on the base 5 and connected to the suction pipe 4. The annular pipe 7 is arranged in a circular shape. The air inlet 8 is horizontally positioned through the bottom of the annular pipe 7 and is conveniently located on the tangent plane at the bottom of the annular pipe 7.
[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the monitoring and alarm structure 3 includes an exhaust pipe 9, a reaction chamber 10, a hydrogen fluoride gas detector 11, a high-sensitivity sensor head 12, a transmission line 13, and an alarm 14. The exhaust pipe 9 is connected to the exhaust port of the blower 1, and the reaction chamber 10 is connected to the top of the exhaust pipe 9. The hydrogen fluoride gas detector 11 is fixed above the reaction chamber 10. The hydrogen fluoride gas detector 11 uses existing mature technology equipment of model LB-MD4X. The high-sensitivity sensor head 12 passes through the reaction chamber 10, with one end electrically connected to the hydrogen fluoride gas detector 11 and the other end also located inside the reaction chamber 10. The high-sensitivity sensor head 12 is made of copper. One end of the transmission line 13 is electrically connected to the hydrogen fluoride gas detector 11, and the alarm 14 is electrically connected to the other end of the transmission line 13.
[0020] In practical use, the fluorination reactor is set inside the annular pipe 7 on the base 5. When hydrogen fluoride leaks from the fluorination reactor, it quickly flows to the ground. At this time, the blower 1 draws it in through the suction pipe 4, creating a negative pressure inside the annular pipe 7. Air flows into the annular pipe 7 through the air inlet 8 in the middle of the annular pipe 7. Hydrogen fluoride enters the annular pipe 7 through the air inlet 8 and is then quickly discharged into the reaction chamber 10 through the exhaust pipe 9. The high-sensitivity sensor head 12 undergoes an electrochemical reaction with the hydrogen fluoride, generating an electric current. This current signal is converted into an alarm signal in the hydrogen fluoride gas detector 11 and then transmitted to the alarm 14 through the conduction line 13 for timely alarm. This allows for the detection of leaks at the first moment. The above describes the entire process of using the gas leak monitoring and alarm equipment for the fluorination reactor.
