Abstract

The invention discloses a highly glutinous liquid's revolving liquid loop pipe transport method and device. Through the first pump, loop liquid storage pot is connected with revolving liquid loop synthesizer in which there are two spiral laminas whose phase difference is 180 DEG C. Through the second pump, highly glutinous liquid's storage pot is connected with highly glutinous liquid inner pipe which is in the middle of the synthesizer. Exit end of the synthesizer is connected with exit pipe in which there is spiral lamina. Rotary motion is generated while the liquid loop is moving forward in the invention. Liquid loop with higher density always lies around inner wall of the pipe through centrifugal force field generated by rotary motion. On the contrary, oil phase with lower density lies in the center of the pipe for lesser centrifugal force. Adopting the invention, driver fee and plenty of fuel oil is saved. In the process of fluxion, liquid film at two phases' interface will not break up to beget two phase liquids' blend.

Description

The rotating liquid ring pipeline delivery method and the device thereof of high viscosity fluid
Affiliated technical field
The present invention relates to the fluid line conveying technology, relate in particular to a kind of rotating liquid ring pipeline delivery method and device thereof of high viscosity fluid.
Background technique
Oil comprises the viscous crude that resource potential is huge, is the modern most important energy.The development of petroleum industry is directly connected to various countries' process of industrialization, and the conveying of crude oil then is the pith of petroleum industry.Owing to line transportation is compared with other delivery method (transporting as train, automobile, oil carrier etc.) and is had obvious superiority to be developed rapidly on Technological Economy.
Crude oil has vicidity, and especially the crude oil of China belongs to paraffin stock more, has the high content of wax, height contains glue, high pour point, full-bodied characteristics, and these characteristics make crude oil will consume very big power when line transportation, can't manage defeated sometimes even at normal temperatures.Therefore the method for taking usually is a heating conveying method, this method also be present stage China to the main delivery method of the glutinous crude oil of height.In order to keep the oil temperature more than wax precipitation point, when carrying, long-distance pipe need consume a large amount of energy by the station heating, and simultaneously oily temperature rise meeting increases the evaporating loss of light ends in the crude oil, and environment is polluted.According to estimates, China every year can reach about 0.5% of pipeline oil transportation amount consuming fuel oil aspect the crude pipeline transportation, is equivalent to have the whole year 760000 tons of crude oil to be used to heat petroleum pipeline.Be not difficult to infer that the annual fuel oil that consumes aspect crude pipeline transportation in the whole world will be very surprising.
Liquid jacket transportation is that the liquid (as water) with low-viscosity forms pendular ring around the inner tube wall and the center portion that high viscosity crude oil is limited in pipeline flowed and a kind of technology of carrying.Because what directly contact with tube wall is thinlyfluid, thereby at normal temperatures, compare when sticking Crude Oil Transportation that resistance greatly reduces in the flow process with height.And be in the crude oil of tube hub, and how high no matter viscosity has, even be curdled appearance, all can be than carrying out line transportation under the low flow resistance.Obviously, the big advantage that utilization Liquid jacket transportation technology transports crude oil is exactly to save power cost greatly, and bigger advantage has been to save a large amount of fuel oil.So, aspect Crude Oil Transportation, the Liquid jacket transportation technology that can under the normal temperature low flow resistance, carry be subjected to people great attention and by a large amount of research.Yet, in the Liquid jacket transportation process, owing to have Rayleigh-Taylor (Rayleigh-Taylor) and Kelvin-Helmholtz (Kelvin-Hai Mu hertz) unstability, be the oil density at core place occur less than the density of water in the pendular ring eccentric flow and in flow process two-phase fluid liquid film is broken and cause the mixing of two-phase fluid at the interface, and the destruction that finally causes pendular ring, it is actual to make that this technology is difficult to directly apply to industry.Therefore, how to make pendular ring in movement process, keep the stable key issue that has just become the Liquid jacket transportation technology.
Summary of the invention
The object of the present invention is to provide a kind of rotating liquid ring pipeline delivery method and device thereof of high viscosity fluid, the bigger pendular ring of density is in around the inner tube wall all the time, and the less oil phase of density is in the pipeline middle part and carries owing to centrifugal force suffered in centrifugal field is less.
In order to achieve the above object, the technical solution used in the present invention is as follows:
