The arbitrary and all combination of one or more related Listed Items.
Referring to Fig. 1, as illustrated, the horizontal pipe moisture content detecting system of the present embodiment includes horizontal straight tube 1, set
Drainage liquid trap 2 in the bottom of horizontal straight tube 1, and the detecting device for moisture content 3 installed in drainage liquid trap 2 stage casing, drainage
The entrance 21 of liquid trap 2 and outlet 22 are connected with horizontal straight tube 1, drain the entrance 21 of liquid trap 2 and export 22 respectively with water
Predetermined angle is formed between straight pipe 1.
Wherein, the both ends of horizontal straight tube 1 are provided with flange 4.
Wherein, the distance between 22 centers of entrance 21 and outlet of liquid trap 2 are drained and are more than 100mm.
Wherein, it is identical with the angle between horizontal straight tube 1 that entrance 21 and the outlet 22 of liquid trap 2 are drained, and angular range is
10-60 degree.Such as 15,25,30 degree etc..
Wherein, it is the equal circle of diameter to drain the entrance 21 of liquid trap 2 and outlet 22, and the diameter range of circle is
0.1D-0.5D。
Wherein, the stage casing for draining liquid trap 2 is parallel with horizontal straight tube 1.
Wherein, detecting device for moisture content 3 can carry microwave detecting unit, the electricity that on-line checking is carried out to moisture content simultaneously

Horizontal pipe moisture content detecting system of the present utility model is mainly used in the multiphase flow water content detection of horizontal pipe,
It can effectively solve the problem that the complicated technical problem of the device and method process for detecting multiphase flow metering in the prior art.
During specific implementation, its implementation process is as follows：
When oil-gas-water multiphase flow horizontally enters into horizontal straight tube 1 from entrance, because the lamination of gravity, gas phase are 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 stablized 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 positioned at level from entrance 21
The drainage liquid trap 2 of the bottom of straight tube 1, and export 22 from it and import again in 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 of drainage liquid trap 2 will not be entered.
By be arranged on drainage liquid trap 2 on liquid phase detecting device for moisture content 3 to flow through drainage liquid trap 2 in liquid phase
Detected, you can obtain liquid phase moisture content information in oil-gas-water multiphase flow.
Because the both ends for draining liquid trap 2 are connected with horizontal straight tube 1, therefore liquid phase will not produce into after draining liquid trap 2
It is raw to stagnate.This can ensure that while the flowing of 1 each phase medium of horizontal straight tube is not influenceed, and make the liquid phase medium in drainage liquid trap 2
Moisture content keeps real-time update with horizontal pipe 1.
Detailed description of the above-mentioned the utility model embodiment combination accompanying drawing to technical scheme, it will be understood that the utility model
