Abstract

The invention discloses a piston-type underwater free gas sampler and a using method thereof. The piston-type underwater free gas sampler comprises an exhaust pipe, a stop valve, a fastening pressure cap, cylinder covers, a cylinder plug, a cylinder body, a handle, a piston, a gas collecting pipe and a drain pipe, wherein the cylinder covers are respectively arranged at the upper end and the lower end of the cylinder body, the piston, the gas collection pipe and the drain water are arranged on the cylinder cover at the lower end of the cylinder body, the exhaust pipe is arranged on the cylinder cover at the upper end of the cylinder body and fixed by the fastening pressure cap, and the stop valve is arranged on the exhaust pipe. In order to satisfy the sampling requirement on liquid-level bubbles, the piston-type underwater free gas sampler and the using method thereof can finish the collection of bubbles on water surface and liquid surface, and transfer and store collected gases in a special container after sampling. The invention has the advantages of simple structure and convenient use, is suitable for collecting underwater methane, underwater leaked hydrocarbon and bubbles on water surface and liquid surface of associated gases in a hot spring, and can transfer and store the collected gases in the special container.

Description

technical field [0001] The invention relates to a piston type free gas sampler in water and a using method thereof. Background technique [0002] The emergence of bubbles in natural water bodies is an important natural phenomenon, such as underwater biogas, underwater hydrocarbon leakage, and associated gas in hot springs. Some artificial processes are also accompanied by emissions of gaseous components, such as fermentation processes. The composition and isotope composition of these gas components are of great significance to the understanding of natural and industrial processes. In the process of scientific research and quality control, it is often necessary to collect water surface and liquid surface bubbles for component analysis or other analysis. The gas has no fixed form and is easily lost. The sampling process and the process of transferring it to a special container for storage after sampling require the use of special tools and techniques. [0003] In order to me...
