Abstract
The utility model discloses an oil gas geochemical exploration trace gas collecting device. The device is technically characterized by comprising a sealed grinding tank, a gas collecting bottle and a vacuumizing pump, wherein the vacuumizing pump is communicated with the sealed grinding tank through an exhausting pipeline; the sealed grinding tank is connected with the gas collecting bottle above the sealed grinding tank through a gas transmission pipeline; the bottom of the sealed grinding tank is communicated with a liquid storage bottle internally containing saturated salt water through a gas driving pipeline; an exhausting valve is arranged on the exhausting pipeline; a vacuum measuring meter and a gas transmission valve are arranged on the gas transmission pipeline; the gas transmission valve is close to the gas collecting bottle; and a liquid discharging valve is arranged on the gas driving pipeline and is close to the liquid storage bottle. The oil gas geochemical exploration trace gas collecting device provided by the utility model has the advantages of simple and reasonable structure design, convenience and rapidness in use, and time and labor saving, and can be used for sufficiently collecting gas in soil.
Description
Technical field:
The utility model belongs to oil and gas geochemistry research and application, is specifically related to a kind of oil and gas geochemical exploration minimum gas gathering-device.
Background technology:
In carrying out oil and gas geochemistry research and using, the gas in the needs collection soil is so that detect.All is to utilize principle of negative pressure at present, extracts gas in the collector, and then injecting gas preserves in the container with syringe, its complex operation, waste time and energy, gas runs off easily.
The utility model content:
The purpose of this utility model provides a kind of oil and gas geochemical exploration minimum gas gathering-device, and its structural design advantages of simple is convenient to use, time saving and energy saving, can fully collect the gas in the soil.
The purpose of this utility model realizes in the following manner: this oil and gas geochemical exploration minimum gas gathering-device, the technical scheme that adopts is: comprise that sealing rolls jar, gas receiving flask and vacuum pumping pump, described vacuum pumping pump rolls jar by the pipeline communication seals of bleeding, sealing rolls jar is connected at its top by gas transmission line gas receiving flask, the bottom that sealing rolls jar is communicated with the inner liquid storage bottle that saturated brine is housed by the purging pipeline, and the described pipeline of bleeding is provided with evacuating valve; Described gas transmission line is provided with vacuum measurement meter and gas transmission valve, and described gas transmission valve is provided with near the gas receiving flask; Be provided with the tapping valve near liquid storage bottle on the described purging pipeline.
The beneficial effects of the utility model are: this oil and gas geochemical exploration minimum gas gathering-device, and the structural design advantages of simple, convenient to use, time saving and energy saving, can fully collect the gas in the soil.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
With reference to Fig. 1, this oil and gas geochemical exploration minimum gas gathering-device, comprise that sealing rolls jar 1, gas receiving flask 2 and vacuum pumping pump 3, described vacuum pumping pump 3 rolls jar 1 by pipeline 6 communication seals of bleeding, sealing rolls jar 1 is connected at its top by gas transmission line 5 gas receiving flask 2, the bottom that sealing rolls jar 1 is communicated with the inner liquid storage bottle 4 that saturated brine is housed by purging pipeline 7, and the described pipeline 6 of bleeding is provided with evacuating valve 9; Described gas transmission line 5 is provided with vacuum measurement meter 11 and gas transmission valve 8, and described gas transmission valve 8 is provided with near gas receiving flask 2; Be provided with tapping valve 10 near liquid storage bottle 4 on the described purging pipeline 7.
During use, at first open evacuating valve 9, start vacuum pumping pump 3 air that sealing rolls in the jar 1 is found time, open gas transmission valve 8 then, sealing is rolled jar 1 interior gas put into gas receiving flask 2, close gas transmission valve 8 at last, can unload gas receiving flask 2.In this process, the saturated brine driving sealing that can open in the tapping valve 10 usefulness liquid storage bottles 4 rolls jar 1 an interior residual gas, and residual gas is entered in the gas receiving flask 2.
