Description

Technical Field

[0001] This utility model relates to the field of dripping system technology, and in particular to a safe dripping system for bromine. Background Technology

[0002] Bromine is the only non-metallic element that is liquid at room temperature. It is a dark reddish-brown liquid with an irritating odor. Bromine is a highly corrosive material with strong penetrability, and it is also highly corrosive to equipment. Even a slight leak can corrode surrounding equipment and pipelines. Bromine also has a certain degree of irritation, and contact with it may damage the skin barrier, causing local ulcers and pain. Therefore, safe operation and safe dripping are required when using bromine.

[0003] In the prior art, Chinese Patent No. CN219232291U discloses a bromine dropping device and an oleyl alcohol synthesis system, which has the advantages of achieving precise and quantitative bromine dropping, reducing the release of reaction heat per unit time, and being safer to use. However, in practical applications, there are still some problems. The traditional bromine dropping system transfers bromine from the bromine container to a bromine dropping high-level tank, and then controls the dropping speed from the bottom of the high-level tank through a dropping valve. During the dropping process, because the bromine contains bromine mud, it may sometimes block the valve, causing dropping difficulties and requiring vacuum back-extraction, resulting in unnecessary loss of bromine. At the same time, the sealing ring at the bottom of the bromine metering tank loses its sealing performance after long-term use, which may cause bromine leakage and corrosion of peripheral equipment and pipelines. Therefore, we disclose a safe bromine dropping system. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a safe bromine dripping system to solve the problem that the sealing ring at the bottom of the bromine metering tank loses its sealing performance after long-term use, causing bromine leakage and corrosion of peripheral equipment and pipelines.

[0005] To achieve the above objectives, this utility model provides a bromine safety dripping system, including a fixed frame. A metering tank and a bromination reactor are fixedly connected to the top of the fixed frame. A sealing cap is threaded onto the upper end of the metering tank. A feed pipe, a gas pipe, and a dripping pipe are fixedly sleeved onto the top of the sealing cap. A feeding hopper is fixedly connected to the top of the feed pipe. A vacuum pressure gauge is fixedly connected to the top of the gas pipe. A pressure pipe is fixedly connected to the middle of the gas pipe. The lower end of the dripping pipe is fixedly sleeved onto the bromination reactor. The dripping pipe is U-shaped, with both ends located inside the metering tank and the bromination reactor. A first valve is fixedly connected to the upper ends of the feed pipe, the gas pipe, and the pressure pipe.

[0006] Preferably, a second valve is fixedly connected to both ends of the dripping pipe.

[0007] Preferably, the metering tank is located at the upper end of the bromination reactor, and the dripping pipe extends down to four-fifths of the metering tank from one end of the inner cavity of the metering tank.

[0008] Preferably, the side of the metering groove is T-shaped.

[0009] Preferably, a fixing ring is fixedly connected to one end of the feed pipe, the gas pipe, and the dripping pipe that are connected to the sealing cap; a sealing ring is fixedly fitted to one end of the feed pipe and the gas pipe that are connected to the sealing cap; and a sealing ring is fixedly fitted to both ends of the dripping pipe that are connected to the sealing cap and the bromination reactor.

[0010] Preferably, weighing modules are fixedly connected to both sides of the outer wall of the metering tank.

[0011] The beneficial effects of this utility model are as follows: After the operator adds bromine to the feeding hopper for the first time, the bromine flows into the metering tank through the feed pipe. Then, the first valve between the feed pipe and the feeding hopper is closed, followed by the first valve connecting the gas pipe and the vacuum pressure gauge. Finally, pressure is applied to the inner cavity of the metering tank and the sealing cover through the pressurization pipe. Using the siphon principle, the bromine in the inner cavity of the metering tank enters the reactor through the dripping pipe. After that, when adding bromine again, it is only necessary to open the first valve between the feed pipe and the feeding hopper. There is no need to open a hole at the bottom of the metering tank, which avoids the leakage of bromine in the metering tank. This avoids the problem of bromine looking down onto the surrounding equipment and pipelines, improving the operational safety of the operator and the service life of the equipment and pipelines. By having the dripping pipe located at one end of the inner cavity of the metering tank and extending down to four-fifths of the metering tank, the occurrence of bromine sludge being drawn into the dripping pipe is reduced, thereby reducing the occurrence of bromine sludge clogging the pipeline.

[0012] After the bromine sludge accumulates to a certain level in the metering tank, the connection between the sealing cap and the feed pipe, gas pipe, and dripping pipe can be disconnected. Then, the sealing cap can be rotated to disconnect the connection between the metering tank and the sealing cap, making it easier for staff to handle the bromine sludge precipitated at the bottom of the metering tank. This method is highly practical. Attached Figure Description

[0021] like Figures 1-3As shown, the bromine safety dripping system includes a fixed frame 1. A metering tank 2 and a bromination reactor 10 are fixedly connected to the top of the fixed frame 1. A sealing cap 3 is threadedly connected to the upper end of the metering tank 2. A feed pipe 4, a gas pipe 6, and a dripping pipe 9 are fixedly sleeved on the top of the sealing cap 3. A feeding hopper 5 is fixedly connected to the top of the feed pipe 4. A vacuum pressure gauge 7 is fixedly connected to the top of the gas pipe 6. A pressure pipe 8 is fixedly connected to the middle of the gas pipe 6. The lower end of the dripping pipe 9 is fixedly sleeved to the bromination reactor 10. The dripping pipe 9 is U-shaped, with both ends located inside the metering tank 2 and the bromination reactor 10. A first valve 12 is fixedly connected to the upper ends of the feed pipe 4, the gas pipe 6, and the pressure pipe 8. A second valve 14 is fixedly connected to both ends of the dripping pipe 9. Measuring tank 2 is located at the upper end of bromination reactor 10. The dripping pipe 9 extends from one end of the inner cavity of measuring tank 2 to about four-fifths of the tank's length. During use, measuring tank 2 and bromination reactor 10 are fixedly connected via the top of the fixing bracket 1, thus fixing their positions. A sealing cap 3 is threaded onto the upper end of measuring tank 2, forming a sealed space between the inner cavities of measuring tank 2 and sealing cap 3. A feed pipe 4, a gas pipe 6, and the dripping pipe 9 are fixedly connected to the top of sealing cap 3. A feeding hopper 5 is fixedly connected to the top of feed pipe 4. A vacuum pressure gauge 7 is fixedly connected to the top of gas pipe 6, and a pressure pipe 8 is fixedly connected to the middle of gas pipe 6. The lower end of the dripping pipe 9 is fixedly connected to bromination reactor 10. The dripping pipe 9 is U-shaped. The two ends of the dripping pipe 9 are located inside the metering tank 2 and the bromination reactor 10. The upper ends of the feed pipe 4, gas pipe 6, and pressurizing pipe 8 are all fixedly connected to a first valve 12. This allows the bromine to flow into the metering tank 2 through the feed pipe 4 after the first dripping of bromine into the feeding hopper 5. Then, the first valve 12 between the feed pipe 4 and the feeding hopper 5 is closed, followed by the first valve 12 connecting the gas pipe 6 and the vacuum pressure gauge 7. Finally, pressure is applied to the inner cavity of the metering tank 2 and the sealing cover 3 through the pressurizing pipe 8. Using the siphon principle, the bromine in the inner cavity of the metering tank 2 flows into the dripping pipe 9 and drips into the bromination reactor 10. Subsequent dripping of bromine only requires opening the first valve 12 between the feed pipe 4 and the feeding hopper 5; no further pressure is needed. The bottom of the metering tank 2 is perforated to prevent bromine leakage, thus avoiding the problem of bromine being visible above surrounding equipment and pipelines. This improves the operational safety of personnel and the service life of equipment and pipelines. Both ends of the dripping pipe 9 are fixedly connected to second valves 14. The metering tank 2 is located at the upper end of the bromination reactor 10, allowing the second valves 14 at both ends of the dripping pipe 9 to be closed when the pressurizing pipe 8 pressurizes the metering tank 2. This allows the bromine in the metering tank 2 to smoothly enter the bromination reactor 10 under pressure. The dripping pipe 9 extends down to four-fifths of the metering tank 2 from one end of its inner cavity, reducing the likelihood of bromine sludge being drawn into the dripping pipe 9 and thus minimizing the occurrence of bromine sludge clogging the pipes.

[0022] As a preferred embodiment of this example, Figure 2 As shown, the side of the metering tank 2 is T-shaped. The ends of the feed pipe 4, gas pipe 6, and dripping pipe 9 that connect to the sealing cap 3 are all fixedly connected with retaining rings 11. The ends of the feed pipe 4 and gas pipe 6 that connect to the sealing cap 3 are also fixedly connected with first sealing rings. The ends of the dripping pipe 9 that connect to the sealing cap 3 and the bromination reactor 10 are both fixedly connected with second sealing rings. Weighing modules 13 are fixedly connected to both sides of the outer wall of the metering tank 2. The T-shaped side of the metering tank 2 ensures a good seal between the metering tank 2 and the sealing cap 3, reducing the possibility of bromine leakage. The ends of the feed pipe 4, gas pipe 6, and dripping pipe 9 that connect to the sealing cap 3 are all fixedly connected with retaining rings 11. The ends of the feed pipe 4 and gas pipe 6 that connect to the sealing cap 3 are also fixedly connected with first sealing rings. The metering tank 2 is equipped with a first sealing ring, and the two ends of the dripping pipe 9 that are connected to the sealing cover 3 and the bromination reactor 10 are also fixedly fitted with second sealing rings. This allows the connection between the sealing cover 3 and the feed pipe 4, gas pipe 6 and dripping pipe 9 to be disconnected after the bromine mud accumulates to a certain level. Then, the sealing cover 3 is rotated to disconnect the connection between the metering tank 2 and the sealing cover 3, which makes it easy for the staff to handle the bromine mud precipitated at the bottom of the metering tank 2. It is practical, and the first and second sealing rings fitted on the outer walls of the feed pipe 4, gas pipe 6 and dripping pipe 9 are easy to replace after aging, ensuring the sealing between the metering tank 2 and the sealing cover 3. The fixing ring 11 also makes it easy for the staff to position the relative positions of the feed pipe 4, gas pipe 6 and dripping pipe 9 and the sealing cover 3, which is convenient for installation.
