Description
Technical field: the row who the present invention relates to the colliery coal bed gas adopts construction technology, especially coal bed gas extraction well skid integrated flow device and application process.
Background technology: in the row of coal bed gas adopts work progress, two phase separator and row's sampled-current journey are the piths of row fief face facility, usually after eliminator, are being divided into two, gas circuit and water route, and conventional two phase separator is expensive, difficulty of processing is large, and the design of flow process is lack of standardization.
summary of the invention: the purpose of this invention is to provide coal bed gas extraction well skid integrated flow device and application process that a kind of integrated gas circuit and water route are integrated, it has overcome the shortcoming that present technology exists, the object of the present invention is achieved like this, it is by body, fluid reservoir, water meter, the discharge opeing adjuster, pressure meter, strainer, valve, gas meter, flow control valve, the type of respiration Liquid level adjusting valve, ball float, outlet blowdown integral valve, blowoff valve, water goes out valve and is formed by connecting, fluid reservoir is installed on body, in the outside of fluid reservoir, the discharge opeing adjuster is installed, fluid reservoir, the centre of discharge opeing adjuster is installed with the two-way water meter, order is installed with pressure meter, strainer, valve, gas meter, flow control valve from right to left on the body extract duct, type of respiration Liquid level adjusting valve and outlet blowdown integral valve are installed in fluid reservoir, on tank body, are connecting outlet blowdown integral valve, on outlet blowdown integral valve, blowoff valve and outlet valve are installed.
Application process of the present invention is: when liquid level in fluid reservoir descended, ball float descended, and abdicates respiration channel, realizes respiratory function, and a small amount of gas can be realized exchange by passage; When liquid level in fluid reservoir progressively raises, when ball float rises to precalculated position, close respiration channel, increased discharge pressure, prevent that liquid level from continuing the generation that rising causes excessive tank; For the large characteristics of the aquifer yield excursion of coal bed gas extraction well, designed the two-way water meter measurement, in the situation that flow is very little, use the single channel metering; In the ever-increasing situation of flow, two-way measures simultaneously, and in order to guarantee accurate measurement, the coefficient of fullness when the adjustable discharge opeing adjuster in front and back has improved water meter measurement, guarantee accurate measurement.
Meaning of the present invention is: the present invention has simplified cyclone separator arrangement, make it become not pressure resistant vessel, and integrated gas circuit and water route are integrated, small and exquisite convenient, installation and transportation are easy to maintenance, and are with low cost, facilitate electronics collection and artificial collection of various data, shorten job site flow process processing and connect hours, improved the construction timeliness; Improved measuring accuracy; Greatly improved the flow measurement scope; Reduced the operation of adjusting flow meter; Coefficient of fullness while having improved water meter measurement, guarantee accurate measurement; The dismounting of water meter and change convenient; Due to the design of outlet blowdown integral valve, the on-the-spot connection water entrance that only needs gets final product, faster convenience.
