Embodiment Construction
[0023] Below in conjunction with accompanying drawing, structure of the present invention is further explained:
[0024] Specifically, such as Figure 1-Figure 4 As shown, the present invention provides a gas-liquid mixture collection and separation device, which includes a collection chamber 1, a catheter 2 and a sampler 3, and the collection chamber 1 is divided into a first collection chamber 10 with a first piston 100 and a first collection chamber 10 with a first piston 100. There is a second collection chamber 20 with a second piston 200 . The first collection chamber 10 and the second collection chamber 20 are fully enclosed structures, which can effectively prevent gas leakage and volatilization. The first collection chamber 10 is connected to the catheter 2 to collect the gas-liquid mixture. During the collection process, the gas and a part of the liquid enter the second collection chamber 20. After the liquid collection in the first collection chamber 10 is complete...

Abstract
The invention provides a gas-liquid mixture collection and separation device. The gas-liquid mixture collection and separation device comprises a collection chamber, a liquid guide pipe and a sampling device, wherein the collection chamber comprises a first collection chamber which is provided with a first piston and used for collecting liquid, and a second collection chamber which is provided with a second piston and used for collecting gas; the first collection chamber is communicated with the second collection chamber by a first gas collection pipe; the first end of the liquid guide pipe is connected with a mixture of liquid to be sampled and gas, and movably sleeves the second end of the liquid guide pipe in a sealed manner; the second end of the liquid guide pipe is inserted into the first collection chamber in a sealing manner and extends to the bottom of the first collection chamber; the first piston can slide up and down along the side wall of the first collection chamber in an airtight manner; and the second piston can slide up and down along the side wall of the second collection chamber in the airtight manner. According to the gas-liquid mixture collection and separation device, the sealing performance is improved, and a gas-liquid mixture can be acquired; and the volatilization and leakage of gas in the gas-liquid mixture is effectively prevented so that the problem that acquired data is not accurate is avoided.
Description
technical field [0001] The invention relates to the field of groundwater collection, in particular to a gas-liquid mixture collection and separation device with an improved sealing structure. Background technique [0002] In many groundwater detection processes, it is not only necessary to detect the content of liquid components in the groundwater body, but also to detect the content of gas components contained in the groundwater body in some places. The wide-mouth bottle is used to collect directly from the port where the fluid flows out or the liquid pool, and there is basically no sealing performance. Most of the incompressible gas and insoluble gas in the fluid volatilize and escape, and the gas phase atmosphere in the underground fluid cannot be collected, so it cannot be accurately known The accurate content of each component in the underground fluid will bring inconvenience to future work. [0003] On the one hand, if the underground flow contains toxic and harmful g...
