After the technical scheme is adopted, the natural gas seepage in-situ flow detector using the impeller method can change the magnetic flux by rotating a blade, generate an electrical impulse signal, and finally change the electrical impulse signal into an impulse wave and transmit the impulse wave to the control device, thereby aiming at the pressure environment conditions of different water depths to measure the seepage flow of natural gas. The natural gas seepage in-situ flow rate detector using the impeller method has the technical advantages that the detection speed is quick; and the detection is accurate.
Description
Technical field
The utility model relates to a kind of gas seepage sniffer, belongs to the measuring equipment field.
Background technology
Gas hydrate (Natural Gas Hydrate, be called for short Gas Hydrate) are to be distributed in the abyssal sediment, and the class that under the high pressure low temperature condition, is formed by rock gas and water is iced the crystalline material of shape.Because of its outward appearance is an incendivity as ice and chance fire, so be known as " combustible ice " perhaps " solid gas " and " gas ice " again.
Methane air water inclusion compound is common composition in the shallow water ecosphere of ocean, and they appear in the sediment structure of deep layer usually, or exposes at the sea bed place.Methane air water inclusion compound is the gas transfer because of geographical tomography depths by inference, and effects such as deposition, crystallization, in the gas stream that rises contact with the cold water of benthos form.
In case temperature raises or pressure reduces, methane gas then can be overflowed, and solid hydrate just is tending towards disintegration, and then discharges rock gas, therefore, needs a kind of sniffer that its seepage discharge is detected.
