Description
Technical field
The utility model relates to pour point depressant for crude oil effect optimum decision system, specifically pour point depressant for crude oil pour point depression effect evaluating device.
Background technology
High solidifying oil refers to because wax content is high, namely is condensed into solid-state crude oil under higher temperature, and high solidifying oily solidifying point is generally more than 30 ℃.For reducing condensation point of crude oil, improve high solidifying oily exploitation effect and the defeated efficient of pipe, the scientific research personnel has developed all kinds of pour point depressant for crude oil, and the pour point depression amplitude is at 10～30 ℃.In the research and development and effect preferred process of pour-point depressant, need pour-point depressant and the two or more pour-point depressant of variety classes, different working concentrations are estimated by the composite effect of variable concentrations, instruct the research and development of pour-point depressant according to evaluation effect, evaluate workload is large.
The pour-point depressant effect assessment is used the condensation point tester more at present, in the test of diesel oil, lubricating oil condensation point, 2～4 holes is arranged generally but the condensation point tester is multiplex, and test quantity is few; And condenser pipe puts condenser jacket outward, adopts air cooling, and the test duration is long.
In view of this, for the problems referred to above, propose a kind of reasonable in design and effectively improve the pour point depressant for crude oil pour point depression effect evaluating device of above-mentioned disappearance.
Summary of the invention
The purpose of this utility model is to provide pour point depressant for crude oil pour point depression effect evaluating device, can reduce the time of pour point depressant for crude oil pour point depression effect assessment experiment, increases to estimate quantity, improves assess effectiveness.
In order to reach above-mentioned purpose, the utility model has adopted following technical scheme, and pour point depressant for crude oil pour point depression effect evaluating device comprises water bath device, condenser pipe support, condenser pipe; Described water bath device is offered water bath, and splendid attire water in water bath, described condenser pipe prop up in the water that is placed in water bath, and described condenser pipe support designs for Dual-layer, and Dual-layer all offers a plurality of circular holes, and described condenser pipe is fastened in circular hole.
Be provided with the water heating and cooling that to control in water bath and the control desk that circulates on described water bath device.
The size of described water bath is slightly larger than the size of condenser pipe support.
Described condenser pipe support upper strata circular hole be used for to stop condenser pipe to fall and blocks condenser pipe, and lower floor's circular hole is used for fixedly the condenser pipe lower end and prevents that condenser pipe from swinging at mobile recirculated water; The height of condenser pipe support guarantees that the condenser pipe bottom is suspended in recirculated water.
The circular hole quantity that described condenser pipe support levels is offered offers 10 respectively at least.
Compared to prior art, the utlity model has following beneficial effect:
The utility model can be estimated the pour-point depressant of 10 variety classeses or concentration, and assess effectiveness is high; Can be according to size and the hole count of the big or small adjusting pole of water bath, to test more sample.Condenser pipe is stuck on frame, and condenser pipe bottom is suspended in recirculated water, and cooling is fast, and testing efficiency is high.
