Description
Technical field
The utility model relates to the online liquid sampling technical field of not separating measuring products or fields such as chemical industry, environmental protection in oil field, particularly a kind of polyphasic flow liquid real-time online sampler.
Background technology
Manual sampling method is mostly adopted in crude oil pipeline sampling at present, and manual sampling is little because of its sampling frequency, is subject to influences such as oil transportation operating mode, human factor, and sample representativeness is poor, and the handing-over metering dispute of Yin Faing is increasing therefrom.Though popular on-line automatic sampler can overcome the part defective of manual sampling on the market, property performance period is taken a sample automatically, avoided because of the oil transportation working conditions change, the problem of the unequal sample representativeness difference that causes of oil, eliminate artificial factor, improve the representativeness of sample, but its huge structure is unfavorable for on-the-spot the popularization, sampling ratio is lower; Especially it is high that the valve of frequent movement makes its failure rate, and liquid can't reclaim and causes environmental pollution easily.Though the simple type sampler is simple in structure, failure rate is low, but principle is too simple, and the accuracy of sampling is very poor.
The utility model content
Technical problem to be solved in the utility model is exactly to overcome large-scale self-actuated sampler complex structure, failure rate height, shortcoming that sampling ratio is low, avoid the shortcoming of the representative difference of simple type sampler simultaneously, use siphon principle and realize the automatic sampling of liquid, the sampling accuracy is not subjected to variable effects such as operating mode, dielectric viscosity, pressure, temperature, provide a kind of and can improve sampling ratio, increase samples' representativeness, simplify product structure, reduce a kind of polyphasic flow liquid real-time online sampler of the failure rate of product.
Technical matters of the present utility model adopts following technical proposals to solve:
A kind of polyphasic flow liquid real-time online sampler, comprise that a container, container side wall top connect a heterogeneous fluid and enters pipeline, container top connects the gas outlet pipe road, and container bottom connects sampling liquid discharge tube road, and sampling liquid discharge tube road is communicated with header; Described container side wall inserts an inverted U siphon Drainage pipe in the container, and the inlet of described siphon Drainage pipe is located in the container, and outlet is located at outside the container, and the height of outlet is lower than the 5cm at least that enters the mouth; Establish a division board between the inlet below of described siphon Drainage pipe and the sampling liquid discharge tube road, the outlet of siphon Drainage pipe directly links to each other with header.
Be connected with the phase fraction measurement instrument between below, described sampling liquid discharge tube road and the header.
The distance of described siphon Drainage pipe lower edge and division board be the U trap diameter 1/2-2 doubly between.
The utility model is used the automatic sampling that siphon principle is realized liquid, the sampling accuracy is not subjected to variable effects such as operating mode, dielectric viscosity, pressure, temperature, promptly overcome large-scale self-actuated sampler complex structure, failure rate height, sampling ratio is low and the irretrievable shortcoming of liquid, has avoided the shortcoming of the representative difference of simple type sampler again.Have that novel in design, simple in structure, safe and reliable, easy for installation, with low cost, Maintenance free and sampling amount are big, the sampling precision advantages of higher, heterogeneous measuring products is reduced cost of products, improving the phase fraction measurement precision has remarkable benefit.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated:
The utility model comprises a container 8 of vertically installing, and container 8 side wall upper part connect a heterogeneous fluid and enter pipeline 1, and heterogeneous fluid enters the position, middle and upper part that pipeline 1 is positioned at container 8, is the underriding angle and tangentially inserts container 8.Container 8 tops connect gas outlet pipe road 2, and container 8 bottoms connect sampling liquid discharge tube road 3, and sampling 3 belows, liquid discharge tube road connect phase fraction measurement instrument 6, and sampling liquid discharge tube road 3 is communicated with header 9 through the phase fraction measurement instrument.Insert an inverted U siphon Drainage pipe 4 in the container 8 from container 8 sidewalls, siphon Drainage pipe 4 tops are lower than the inlet that heterogeneous fluid enters pipeline 1, and the outlet 11 of siphon Drainage pipe 4 outside container 8 is lower than more than the height 5cm of inlet 10; Inlet 10 belows of siphon Drainage pipe 4 are provided with a division board 5, the lower edge of siphon Drainage pipe 4 inlet 10 and the distance of division board 5 be the U trap diameter 1/2-2 doubly between, the siphon Drainage pipe exports 11 and directly is communicated with header 9; Gas outlet pipe road 2 directly is communicated with header.
After heterogeneous fluid (oil gas water three phase medium) tangentially is the underriding angle and enters container from the top of container, by self gravity and kinetic energy along the container inner wall rotation downwards, isolated gas is discharged from the top gas outlet of container rapidly; The sampling delivery outlet that is positioned at container bottom is exported sampling liquid continuously.Enter the liquid measure of container when big liquid level can progressively raise, after liquid level reaches siphonal top, can produce siphonic effect, distribute a large amount of excess liquid by U trap, because leakage fluid dram distance sampling mouth is very near, so the liquid components that both discharge is very approaching, reaches the purpose of uniform sampling with this.
The course of work:
During low consumption of the liquid, the amount of fluid that enters container is less, and liquid level is lower always, does not reach the height at U trap top, and all liquid is all discharged from stopple coupon, realizes sampling entirely, makes the accuracy of sampling reach 100%.
During medium liquid measure, enter the liquid measure of the amount of fluid of container greater than stopple coupon output, liquid level can continue to raise.After liquid level is higher than siphonal top, has liquid and discharge from U trap; After the siphonal liquid column length of discharge reaches certain value, can form siphonage, along U trap discharge liquid container in apace by syphonic effect this moment, drops to the height that U trap enters the mouth up to liquid level, till siphonic effect is destroyed.After this liquid level can rise again, the action above repeating, and circulation repeatedly realizes the discharge of automatic control of liquid level and unnecessary liquid.Because siphonal entry position and sample tap position distance are very near, therefore the component by U trap liquid of discharging and the liquid of discharging by sample tap has kept relative unanimity, has guaranteed higher sampling accuracy.
During big liquid measure, the liquid measure that enters container is very big, and after liquid level continued to rise, U trap presented the situation of continuous draining.Although this moment is because the fluid of sample tap and U trap leakage fluid dram is limited in one's ability, may occur along the situation of gas exhaust piping discharge opeing, but because the flow rate of liquid that enter in the container this moment is bigger, momentum is very big, the immixture that self produces is very remarkable, the time that in addition stops in container is very of short duration, and the lamination of liquid is very faint, and therefore its representativeness of liquid that obtains from sample tap still is higher.
This shows that this sampler can obtain higher sampling accuracy in bigger flow range.
