Abstract
The utility model relates to a sand-prevention blockage-prevention functional structure piece of a sampler of a crude oil storage tank. The functional structure piece is a T-shaped antenna type sampling pipe, wherein the lower side of a cross pipe section of the sampling pipe is provided with a sampling port group, the orifice of the sampling pipe face downward. and a sand-prevention blockage-prevention function is obvious particularly during sampling in the crude oil storage tank with higher sand impurity content.
Description
Affiliated technical field
The utility model relates to a kind of sand control choke preventing function structural member of crude oil storage tank sampling thief; Adopt T antenna formula sampling pipe, its horizontal segment downside is arranged the thief hatch crowd, and the aperture direction down; Especially in the higher crude oil storage tank of sediment contamination content, sample, its sand control choke preventing function is particularly remarkable.
Background technology
At present, the crude oil storage tank sampling is divided into tank deck sampling and two kinds of jar down-samplings, and the tank deck sampling needs manual work to climb to tank deck, and utilization sampling bucket is sampled, and danger coefficient is high, and efficient is low, and precision can not guarantee; By contrast, a jar down-sampling has remarkable advantages: the sample collector only needs operation under jar, opens the sample that Sampler valves just can be adopted the relevant position, and is safe, convenient.Yet jar down-sampling causes system jams, inefficacy easily owing to contained sediment contamination in the crude oil is higher.
Summary of the invention
Climb the inconvenience of top sampling in order to overcome manual work, reach jar many, the susceptible to plugging deficiencies of down-sampling silt particle, the utility model provides a kind of sand control choke preventing function structural member.
The utility model solves the technical scheme that its technical matters adopted:
1, crude oil storage tank sampling thief adopts T antenna formula sampling pipe, and its horizontal segment downside is arranged the thief hatch crowd, and the aperture direction prevents that silt particle deposits in the sampling pipe in the storage tank down.
2,4 t-antenna formula sampling pipes that are provided with in the storage tank, its horizontal segment is distributed on the aspect of 4 differing heights, receives material respectively, to guarantee the representativeness of institute's sample thief.
3, also have a small amount of silt suspension to get into system with material from transverse tube downside aperture crowd, the treating method of this part silt particle is:
1), second of silt particle take turns sedimentation:
Material gets into pipeline, because the caliber minimum velocity is fast, when material entered displacement tank, the big flow velocity of caliber eased up, and silt particle obtains second and takes turns sedimentation, falls the bottom in displacement tank.And desired sample is also cleaner comparatively speaking from the shoulder outflow of displacement tank.
2), " telling sand, certainly clear system " effect of functional parts:
When sampling operation procedure stipulation, sampling work get into the 2nd sampling, must at first the material in the system be replaced.The effect of functional parts is: be displacement power with the air pump, air is squeezed into system.Retaining valve is equipped with in displacement tank top, bottom, and is in the opposite direction.Under the effect of retaining valve, marine store expels from the displacement tank bottom, and new material gets into from top.The silt particle that is deposited on the displacement tank bottom is discharged with marine store, reaches to tell the effect of dying, taking in the fresh, tell sand, certainly clear system.
The beneficial effect of the utility model is that jar down-sampling even sediment contamination content is higher in the crude oil, can not cause system jams, inefficacy yet.
Description of drawings
1, Fig. 1, T antenna formula sampling pipe, its transverse tube downside is arranged the thief hatch crowd, prevents that silt particle from depositing in the pipe.
2, Fig. 2, crude oil storage tank sampling thief jar inner assembly are made up of elements such as T antenna tube bank, laterally tube bank, displacement tank, retaining valves.
3, Fig. 3, crude oil storage tank sampling thief fundamental diagram.
In jar: 4 transverse tubes that have the thief hatch crowd of t-antenna tube bank, be distributed on the aspect of four differing heights, as 4 sampled points, receive material, to guarantee the representativeness of institute's sample thief.
Outside jar: function element such as sampling box, inflating pump are set.
4, Fig. 4, displacement tank structure principle chart.Retaining valve is not shown among the figure.When displaced air when the shoulder of displacement tank gets into, two retaining valves work up and down, and marine store and silt particle are discharged from the bottom of displacement tank.
Embodiment
Make t-antenna formula sampling pipe by Fig. 1, thief hatch crowd direction down.
Make displacement tank by Fig. 4.
Press t-antenna formula sampling tube bank, horizontal tube bank, retaining valve are installed in Fig. 2 jar.
Retaining valve: shutter-type, level is installed.
The top of displacement tank, bottom: retaining valve is installed, in the opposite direction.Function is: top fed, bottom discharge.
Displacement tank shoulder: connect the transverse tube bundle, be used for taking a sample, or advance displaced air.
By Fig. 3 jar sampling box and inflating pump are installed outward.Inflating pump is the displacement power source.
