Abstract
The utility model discloses a natural gas leakage in-situ flow rate detection device for a gas collection method, comprising a device body and a gas collection device arranged above the body. An electric valve is arranged above the gas collection device, and a liquid level switch is arranged below the gas collection device; and moreover, the liquid level switch is connected with the electric valve. After adoption of the technical scheme, the natural gas leakage in-situ flow rate detection device for the gas collection method can accurately measure the flow rate of gas through constant opening and closing of the liquid level switch, and has better technical effect.
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.
The utility model content
The utility model is surveyed the shortcoming of difficulty to existing sea-bottom natural gas and is proposed, and a kind of gas collection method gas seepage in-situ flow sniffer is provided, and said device has and detects accurately, surveys technological merit easily.
The utility model solves the problems of the technologies described above the technical scheme that adopted like following description:
A kind of gas collection method gas seepage in-situ flow sniffer; Comprise a device body and a gas collector that is arranged on the body top; Above gas collector, be provided with an electrically operated valve; Below gas collector, be provided with a level switch, and said level switch is connected with said electrically operated valve.
Further, preferred construction is, below the wall of said device body, locates to be provided with water injection hole.
Further, preferred construction is that said level switch links together through lead and control device.
Further, preferred construction is, said control device comprises, the single-chip microcomputer or the CPU that are connected with above-mentioned data collector, and said single-chip microcomputer or CPU adopt RS232/485 and host computer to carry out communication, with the data upload that collects to host computer.
Further, preferred construction is that said device body is the shape of an inverted cone.
The utility model is after having taked technique scheme, and continuous opening and closing that can be through level switch, and then the flow of measurement gas comparatively exactly have better technical effect.
Description of drawings
Below in conjunction with accompanying drawing the utility model is carried out detailed description, so that the above-mentioned advantage of the utility model is clearer and more definite.
Fig. 1 is the structural representation of the utility model gas collection method gas seepage in-situ flow sniffer;
Fig. 2 is the structural representation of the control device of the utility model sniffer.
Embodiment
Come the utility model is carried out detailed description below in conjunction with accompanying drawing and specific embodiment.
Fig. 1 is the structural representation of the utility model gas collection method gas seepage in-situ flow sniffer.
As scheme saidly, said gas collection method gas seepage in-situ flow sniffer has comprised the device body 8 and a gas collector 2 that is arranged on the body top of an inverted cone-shaped; Above gas collector, be provided with an electrically operated valve 1; Below gas collector, be provided with a level switch 3, and said level switch 3 is connected with said electrically operated valve 1; Wherein, the potpourri that has comprised gas and seawater 4 among the said gas collector 2.
And, below the wall of said device body, locate to be provided with water injection hole 6.
In addition, said level switch 3 links together through lead and control device.
In addition, for divided gas flow and seawater preferably, in device body, the place ahead of gas collector 2 is provided with a gas breaking net 5.
Fig. 2 is the structural representation of the control device of the utility model sniffer.
As shown in the figure, said control device comprises, the single-chip microcomputer or the CPU that are connected with above-mentioned data collector, and said single-chip microcomputer or CPU adopt RS232/485 interface and host computer to carry out communication, with the data upload that collects to host computer.
Carry out simple a description in the face of the principle of work of the utility model down.
At first, the rock gas bubble gets into gas collector through the bubble breaking net, discharges seawater simultaneously.When gas is collected level switch position, bottom, produce trigger pip, open electrically operated valve by device controlling recording appearance, discharge gas.In air scavenge, when seawater reaches the top level switch, close electrically operated valve by device controlling recording appearance, continue to collect gas.Device controlling recording appearance writes down electrically operated valve and opens the number of times of cutting out, but the measurement gas flow.
And whether said control device is experienced the level switch signal has opening action (dry contact signal), analysis and judgement then; Open motorized valve and flow out by gas, after gas flowed out, the seawater liquid level began to rise; Liquid level is closed to the certain altitude level switch; After control system received the level switch shutdown signal, control system was closed motorized valve, repeated next samsara process again.
The utility model is after having taked technique scheme, and continuous opening and closing that can be through level switch, and then the flow of measurement gas comparatively exactly have better technical effect.
It should be noted that; Above-mentioned specific embodiment only is exemplary; Under the above-mentioned instruction of the utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improve or distortion drops in the protection domain of the utility model.
It will be understood by those skilled in the art that top specific descriptions just in order to explain the purpose of the utility model, are not to be used to limit the utility model.The protection domain of the utility model is limited claim and equivalent thereof.
