Abstract
The present invention discloses a rotating liquid ring pipeline conveying method and a device for high viscosity liquid. A ring-shaped liquid storage tank is connected with a rotating liquid ring synthesizer by a first pump, and two spiral plates with 180 DEG phase difference are arranged in the rotating liquid ring synthesizer. A high viscosity liquid storage tank is connected with an inner tube by a second pump, the inner tube is arranged at the center of the rotating liquid ring synthesizer, the high viscosity liquid passes through the inner tube, the outlet end of the rotating liquid ring synthesizer is connected with an outlet conduit, and a spiral plate is arranged in the outlet conduit. Liquid rings simultaneously generate rotary motion when the liquid rings move upwards, the present invention generates centrifugal force field by the rotary motion and causes the liquid rings with larger density to surround the inner wall of a pipe all the time, on the contrary, an oil phase with minor density is at the middle part of the conduit because the oil phase suffers from small centrifugal force in the centrifugal force field, and thereby, the high viscosity liquid is transported through the conduit. The present invention considerably saves power cost and saves a large quantity of fuel oil. A liquid film of a two-phase liquid interface is not crushed to cause two phase liquid to mix in a flow process.
Description
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:
