Brief description of the drawings
Fig. 1 is the floor map of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figure 1, this liquid-liquid diphase stratified sampling device comprises that layering container 1 comprises the layering container 1 of column structure, and layering container 1 is placed perpendicular to horizontal line, and its center line overlaps with pedal line; The sidewall of this layering container is provided with injection port a and sample tap.Wherein, injection port a is positioned at the medium position of layering container.In the present embodiment, sample tap has two, is respectively the heavies liquid sample tap b that is positioned at described injection port a below and the light constituent sample tap c that is positioned at described injection port a top.The top of described layering container 1 is provided with light constituent liquid outlet d, and the bottom of described layering container is provided with heavies liquid outlet e.
In the present embodiment, be 5 times of light constituent liquid sampling amount to the volume between light constituent liquid outlet from light constituent liquid sampling mouth position, be about 15mL; The volume of layering container between position to the described injection port position of described heavies liquid sample tap is 6.8 times of described heavies liquid sampling amount, is 34mL, and light constituent liquid sampling mouth is positioned at 30mm place, injection port top.
Injection port a connects sample feeding pipe 2, and the internal diameter of layering container 1 is 25mm, and described sample feeding pipe internal diameter is 5mm, and the internal diameter of layering container 1 is 5 times of sample bore.Sample pipe 2 is provided with flowrate control valve 3; Flow control valve 3 is selected needle valve, and the flow rate of liquid that makes to enter layering container is slow, so that fully layering.Light constituent liquid outlet d connects light constituent liquid discharge sample pipe 4, heavies liquid outlet e connects heavies liquid and goes out sample pipe 5, light constituent liquid discharge sample pipe 4 and heavies liquid go out sample pipe 5 and collect rear connection manifold trunk 6, and light constituent liquid discharge sample pipe 4 and heavies liquid to go out the height that collects height that link position is Rendezvous Point f and described injection port a of sample pipe 5 and manifold trunk 6 identical; The exit position of manifold trunk is higher than light constituent liquid outlet d200mm, higher than the peak of layering container.
Sample tap connects stopple coupon, and stopple coupon is provided with sample cock.Corresponding to two sample taps in the present embodiment, stopple coupon also has two, is respectively the light constituent liquid sampling pipe 7 and the heavies liquid stopple coupon 8 that is connected heavies liquid sample tap b that connect light constituent liquid sampling mouth c; Wherein light constituent liquid sampling pipe 7 is provided with the first valve 9, and heavies liquid stopple coupon 8 is provided with the second valve 10.
The principle of work of this liquid-liquid diphase stratified sampling device is described below:
What process upstream flow process was sent here treats that stratified liquid enters in sample feeding pipe from high-pressure side, after flowrate control valve current limliting, enter the middle part of layering container from injection port, in quantizer, due to the difference of two kinds of liquid self gravitations, the heavies liquid that density is large deposits to layering container bottom under self gravitation effect, and the light constituent liquid that density is little swims in heavies liquid top; After the liquid in layering container is full of, the center line of phase interface, injection port and the light constituent liquid of discharge layering container and the Rendezvous Point of heavies liquid are positioned in same level; Light constituent liquid after layering flows out from the outlet of layering container top, flows out via going out sample pipe; The heavies liquid that density is large flows out from the heavies liquid outlet of layering container bottom, and light constituent liquid and heavies liquid enter manifold trunk after collecting, and are sent to downstream line or equipment.
In the accessible technological process of this liquid-liquid diphase stratified sampling device, to testing sample, real-time stratified sampling detects.In the time of needs continuous stratification, only need in the time that going into operation, open process unit flowrate control valve, mix up after flow, liquid in device forms in real-time update, be consistent with system, when sampling, need not replace again, can directly in light constituent stopple coupon, extract the fluid sample that density is little as required, or the sample that extracts the liquid that density is large from heavy constituent stopple coupon detects.Material after stratified sampling flows out from manifold trunk again, returns in technological process.
The device of this liquid-liquid diphase stratified sampling also can discontinuous operation.In such cases, flowrate control valve is only at sampling front opening, mix up flow, treat the fluid appropriate time that flows, by after liquid displacement in quantizer, component fluids stopple coupon extracts density little fluid sample on the lenient side as required again, extracts the large fluid sample of density from heavies liquid stopple coupon, closes the first valve and/or the second valve after taking sample.
