Trace gas collecting device for geochemical exploration

Abstract

The invention discloses a trace gas collecting device for geochemical exploration, and belongs to the technical field of gas collecting equipment. The trace gas collecting device comprises a storage box with a plurality of collecting bottles; a gas collection pipe is arranged on a side wall of the storage bottle;; a rigid air inlet needle is arranged at one end of air collecting pipe, air outlet needle is arranged at other end of the air collecting pipe, and a rubber plug is arranged at bottle opening of the gas collecting bottle; a pumping filtering mechanism is arranged in the middle of thegas collecting pipe; a turntable is arranged in the bottle storage box, a rotating shaft is arranged in the middle of the turntable, and multiple collecting bottles are radially arranged on the turntable around the rotating shaft. A plurality of collecting bottles are contained in the bottle storage box, the rigid gas inlet needle is not prone to bending in the collecting process and can conveniently go deep into the ground to explore and collect trace gas, and a gas inlet needle opening cannot be severely blocked in the collecting process; underground trace gas is pumped and filtered by utilizing the pumping and filtering mechanism, so that the purity of sample gas can be ensured; the rotating shaft is driven to rotate the turntable to inflate a plurality of collection bottles one by one,so that convenience and rapidness are achieved, and continuous gas collection operation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of gas collection equipment, in particular to a trace gas collection device for geochemical exploration. Background technique [0002] At present, important fossil energy such as oil and natural gas still occupy a very important position in natural resources. Exploitation and utilization of petroleum resources is an important task, and before exploitation, chemical gas exploration needs to be carried out on the place to be exploited. [0003] The commonly used chemical exploration of trace gas is mainly to manually draw a certain amount of gas with a simple injection device at the place where it needs to be collected, and then inject it into a storage bottle. This method is not only time-consuming and laborious, but also difficult to guarantee the purity of the collected sample gas. At the same time, when going deep underground, some flammable, explosive, poisonous and harmful gases also pose a great threa...
