It is mainly used in the petroleum industry, pharmaceutical industry, plastic industry, defense atomic and firefighting industry, dye industry, photography and film technology industry, pesticide industry and other chemical products. The natural resources of bromine mainly exist in seawater, underground brine and salt lake water. Bromine is mostly extracted by air blowing and steam distillation. In the production and use of bromine, bromine water separators are used to separate bromine and bromine water.

[0003] At present, for the separation of bromine water, most of the methods are to extract bromine with a solvent to separate bromine from water, and then evaporate the mixed solution of the solvent and bromine to obtain bromine.

The bromine water separator of the utility model is used for the production of bromine, and has high strength, simple installation, high safety, and large processing capacity.

[0005] Although the above patent can realize the separation of bromine and water, when the bromine is discharged from the cylinder, the separated water is very likely to be discharged along with the bromine, which leads to incomplete separation of bromine and water. In addition, the discharge of bromine and water through the lower outlet and the bromine outlet pipe requires manual control, which is extremely inconvenient to operate.

[0006] In summary, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0031] A first sealing ring 12 and a second sealing ring 13 are arranged at the middle position of the bottom of the extraction cylinder 1.

[0032] The first sealing ring 12 is connected and arranged with the connecting pipe 2.

[0033] The sealing hole 10 is a frustum-shaped blind hole structure, the sealing groove 11 is an annular structure, and the cross-section of the sealing groove 11 is an isosceles trapezoid structure.

[0034] A pressure stabilizing valve 14 is connected and provided at the upper part of the extraction cylinder 1.

[0035] Feeding pipes 15 and solvent pipes 16 are symmetrically arranged on the side wall at the upper part of the extraction cylinder 1. The feeding pipes 15 and the solvent pipes 16 are connected with a conveying pipeline 18 through one-way valves 17, and an electric air inlet valve 19 is connected and arranged on the outer wall of one end of the conveying pipeline 18 connected with the one-way valve 17.

[0040] A pressure stabilizing valve 14 is communicated and provided at the upper part of the bromine tank 3.

[0041] The working principle of the present utility model:

[0042] The solvent pipe 16 injects carbon tetrachloride solvent into the extraction cylinder 1 through the conveying pipeline 18, and the feed pipe 15 injects bromine water raw material into the extraction cylinder 1 through the conveying pipeline 18. The pressure stabilizing valve 14 discharges the air in the extraction cylinder 1. The observation window 24 observes the water level in the extraction cylinder 1. After the mixed solution of the bromine water raw material and the carbon tetrachloride solvent reaches the predetermined water level, the conveying pipeline 18 stops conveying the carbon tetrachloride solvent and the bromine water raw material. The electric intake valve 19 is started, and the carbon tetrachloride solvent and the bromine water raw material in the conveying pipeline 18 flow back to prevent the bromine water raw material and the carbon tetrachloride solvent from staying in the conveying pipeline 18 for a long time and corroding the conveying pipeline 18;

[0043] The circulation pump 5 is started, and the water suction pipe 6 leads the bromine water raw material and the carbon tetrachloride solvent at the bottom of the extraction cylinder 1 into the upper part of the extraction cylinder 1 through the water discharge pipe 7, and uses the water suction pipe 6 to circulate the bromine water raw material and the carbon tetrachloride solvent, so as to mix the bromine water raw material and the carbon tetrachloride solvent. After the circulation pump 5 works for a period of time, the circulation pump 5 stops working, and then the solution in the extraction cylinder 1 is allowed to stand. After standing for a period of time, the water in the bromine water raw material is layered with the carbon tetrachloride solvent, and bromine is dissolved in the carbon tetrachloride solvent. The floating seal block 9 floats on the upper part of the carbon tetrachloride solvent and sinks to the bottom of the water;

[0044] The electromagnetic valve 4 is opened, and bromine enters the bromine tank 3 through the connecting pipe 2. As the liquid level of bromine drops, the floating seal block 9 follows the liquid level of bromine and drops until the sealing hole 10 and the sealing groove 11 of the floating seal block 9 are respectively buckled with the first sealing ring 12 and the second sealing ring 13 to seal the extraction cylinder 1. At this time, part of the bromine and carbon tetrachloride solution remains at the bottom of the extraction cylinder 1. The valve 23 of the residual material pipe 21 is opened to discharge the remaining bromine and carbon tetrachloride solution, which contains part of the water. Then the valve 23 of the drain pipe 20 is opened to discharge the water in the extraction cylinder 1, and the bromine in the bromine tank 3 is discharged through the discharge pipe 22.
