In gas field recovery process, with being continuously increased for the exploitation time limit, in gas well output object, impurity content gradually can increase, generally liquid hydrocarbon and water of the above impurity for condensation, and such natural gas is referred to as condensation natural gas.In prior art, the metering method of this class natural gas is that single-phase measurement is carried out after gas phase and liquid phase separation, but appoints so inaccurate defect of presence metering.Trace it to its cause mainly first in the final stage of exploitation of oil-gas field, with increasing for liquid hydrocarbon in outlet and water content, corresponding gas-liquid phase-separating device can not play due centrifugation；Next to that during the pipeline transmission of detached gas phase, due to the erratic change such as pressure, temperature, precipitation liquid phase that can be again in causing pipeline.Metering of the metering defect on oil and gas content above affects larger, is unfavorable for the fine-grained management of enterprise.
The content of the invention
For problem present in above-mentioned condensation gas metering process, the invention provides a kind of condensation natural gas line metering device of turbine flowmeter easy to use.
The condensation natural gas line metering device of the turbine flowmeter a kind of easy to use provided for the problems referred to above, the present invention reaches goal of the invention by following technical essential：A kind of condensation natural gas line metering device of turbine flowmeter easy to use, including fluid circuit and the metering device being arranged on fluid circuit, knockout drum is in series with the fluid circuit also, the knockout drum is located at the front end of metering device, and the fluid circuit of knockout drum outlet side is connected on the top or side of knockout drum, spiral separator is additionally provided with knockout drum, the spiral separator is provided with entrance for lower end, side is provided with outlet, the barrel-like structure of spiral flow channel is provided between entrance and outlet, the fluid circuit of the knockout drum outlet side is connected in the outlet of spiral separator, drain pipe is additionally provided with the knockout drum, block valve is in series with the drain pipe.
Specifically, using the version that knockout drum is arranged on fluid circuit, it is easy to realize gas-liquid separation by the gravitational difference of gaseous fluid and fluid liquid, and metering device is arranged on into the version on the fluid circuit of knockout drum rear end, facilitate implementation and measured only for gaseous fluid, and realize the gas-liquid separation of condensation natural gas.As the general flow of the fluid liquid of condensation is less, therefore the normally opened form of drain pipe is set and is not easy to follow-up liquid handling or collection, therefore block valve is set on drain pipe, in order to control the open and-shut mode of block valve.Simultaneously, final air-flow is depressed in knockout drum the entrance through spiral separator to be entered in spiral flow channel, again by the outlet of spiral separator in the fluid circuit of knockout drum rear end, so, contain more liquid hydrocarbon in gas stream to be separated or during condensation water or when pending air-flow velocity is larger, preferable steam separating effect cannot be obtained using simple gravitational difference, so, spiral separator is used as a kind of simple structure, during use in addition to possible chemical attack, the gas-liquid separation device of any maintenance work is not needed, be conducive to further reducing the ratio for being suspended in liquid phase in air-flow, while gas-liquid separation effect is strengthened, it is easy to reduce or avoids follow-up such as metering device, compressor, the mechanism of decompressor, the excessive corrosion of combustion apparatus etc..
Further technical scheme is：
Also reduce the version that knockout drum inlet air flow is impacted to condensed liquid as a kind of, the fluid circuit of the knockout drum inlet side is connected to the top of knockout drum.
For ease of the regular removing of solid impurity in knockout drum, it is additionally provided with the bottom of the knockout drum and drains pipe.
Used as a kind of version for being easy to hydrops in emptying knockout drum, the inducer of the drain pipe is connected on the bottom of knockout drum.
As it is a kind of be simple to manufacture, version easy for installation, the knockout drum be two ends for ellipsoidal head pressure vessel.
The invention has the advantages that：
1st, present configuration is simple, using the version that knockout drum is arranged on fluid circuit, it is easy to realize gas-liquid separation by the gravitational difference of gaseous fluid and fluid liquid, and metering device is arranged on into the version on the fluid circuit of knockout drum rear end, facilitate implementation and measured only for gaseous fluid, and realize the gas-liquid separation of condensation natural gas.As the general flow of the fluid liquid of condensation is less, therefore the normally opened form of drain pipe is set and is not easy to follow-up liquid handling or collection, therefore block valve is set on drain pipe, in order to control the open and-shut mode of block valve.
2, final air-flow is depressed in knockout drum the entrance through spiral separator to be entered in spiral flow channel, again by the outlet of spiral separator in the fluid circuit of knockout drum rear end, so, contain more liquid hydrocarbon in gas stream to be separated or during condensation water or when pending air-flow velocity is larger, preferable steam separating effect cannot be obtained using simple gravitational difference, so, spiral separator is used as a kind of simple structure, during use in addition to possible chemical attack, the gas-liquid separation device of any maintenance work is not needed, be conducive to further reducing the ratio for being suspended in liquid phase in air-flow, while gas-liquid separation effect is strengthened, it is easy to reduce or avoids follow-up such as metering device, compressor, the mechanism of decompressor, the excessive corrosion of combustion apparatus etc..
