[0019] Example 1
[0020] like Figure 1As shown, this embodiment provides a sampling system for a liquid material storage tank, wherein the liquid material is stored in a storage tank 1; an exhaust pipeline 14 is connected to the storage tank 1, the exhaust pipeline 14 is connected to the tail gas absorption system, and a pressure relief valve 1401 is provided on the exhaust pipeline 14, and the pressure relief valve 1401 can automatically release pressure when the pressure in the storage tank 1 is too high, so as to avoid a large amount of liquid volatilization causing overpressure in the storage tank 1. The sampling system includes a discharge pipeline 2 connected to the storage tank 1, and a valve 1 201 and a valve 2 202 are provided on the discharge pipeline 2, wherein the valve 1 201 is normally open, and the liquid material is transferred from the storage tank 1 by controlling the opening and closing of the valve 2 202.

In addition, a check valve 301 is also arranged at the discharge port end of the transfer pump 7 on the transfer pipeline 3 to prevent the liquid material from flowing back into the transfer pump 7 after the transfer pump 7 is closed, causing the impeller of the transfer pump 7 to reverse. At the same time, an emptying pipeline can also be connected to the feed port end of the transfer pump 7 on the transfer pipeline 3, and an emptying valve 15 is arranged on the emptying pipeline to facilitate emptying the material in the pipeline when the transfer pump 7 is disassembled.

Before sampling, the valve 6 on the circulation pipeline 4 is opened, and the liquid material in the storage tank 1 is continuously drawn out of the storage tank 1 and pumped back to the storage tank 1 under the action of the circulation pump 8, which lasts for 5-10 minutes, and the liquid material in the storage tank 1 is forced to circulate to ensure the uniformity of the final sample. In addition, an inlet valve 16 and an outlet valve 17 can be respectively provided at the feed port end and the discharge port end of the circulation pump 8 on the circulation pipeline 4 to facilitate the disassembly, maintenance or replacement of the circulation pump 8.
