The advantage of sense technology, realization accurately carries out on-line measurement to multiphase moisture content.
Horizontal pipe moisture content detecting system of the invention is mainly used in the multiphase flow water content detection of horizontal pipe, can
Effectively solve the complicated technical problem of the device and method process of detection multiphase flow metering in the prior art.
During implementing, its implementation process is as follows：
When oil-gas-water multiphase flow horizontally enters into horizontal straight tube 1 from entrance, due to the lamination of gravity, gas phase is main
The top of horizontal straight tube 1 is distributed in, liquid phase is substantially distributed in the bottom of horizontal straight tube 1.When multiphase flow is stable in horizontal straight tube 1
After flowing, due to the rubbing action between multiphase flow and main pipeline tube wall, the static pressure of multiphase flow can gradually drop with the flowing of fluid
It is low.Therefore a pressure differential can be produced between the entrance 21 of drainage liquid trap 2 and outlet 22, and (static pressure at entrance 21 is more than
Export at 22).In the presence of this pressure differential, the liquid phase in the bottom of horizontal straight tube 1 will enter the level of being located at from entrance 21
The drainage liquid trap 2 of the bottom of straight tube 1, and from its outlet 22 again remittance horizontal straight tube 1.And gas phase is due to being mainly distributed on water
The top of straight pipe 1, therefore the entrance 21 in the road of drainage liquid trap 2 will not be entered.
By the 3 pairs of liquid phases flowed through in drainage liquid trap 2 of liquid phase detecting device for moisture content being arranged on drainage liquid trap 2
Detected, you can obtain liquid phase moisture content information in oil-gas-water multiphase flow.
Because the two ends of drainage liquid trap 2 are connected with horizontal straight tube 1, thus liquid phase enter drainage liquid trap 2 after will not produce
It is raw to stagnate.This can ensure that do not influence each phase medium of horizontal straight tube 1 flow while, make the liquid phase medium in drainage liquid trap 2
Moisture content keeps real-time update with horizontal pipe 1.
Detailed description of the embodiments of the present invention combination accompanying drawing to technical scheme, it will be understood that horizontal tube of the invention
Road moisture content detecting system includes horizontal straight tube, the drainage liquid trap of horizontal straight tube bottom is arranged on, installed in drainage liquid trap
The detecting device for moisture content in stage casing, the entrance and exit of drainage liquid trap is connected with horizontal straight tube, the entrance of drainage liquid trap
And outlet forms predetermined angle between horizontal straight tube respectively.By such detecting system, can simply and easily realize
Line moisture content is detected.
Embodiments of the invention are the foregoing is only, the scope of the claims of the invention is not thereby limited, it is every to utilize this hair
Equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
