Abstract
The utility model relates to an ultrasonic wave resonant cavity heave oil delivery pipe. According to the technical scheme, the ultrasonic wave resonant cavity heave oil delivery pipe comprises an outer pipe wall, an inner pipe wall, resonant cavities, a plurality of sets of ultrasonic wave generators and vacuum isolated areas. The outer pipe wall is arranged outside the inner pipe wall. The multiple sets of ultrasonic wave generators are arranged between the inner pipe wall and the outer pipe wall. One side of each ultrasonic wave generator is provided with the corresponding vacuum isolated area, and each resonant cavity is formed outside the corresponding ultrasonic wave generator. Ultrasonic waves are amplified in the resonant cavities and then act on crude oil in the heave oil delivery pipe. The ultrasonic wave resonant cavity heave oil delivery pipe has the advantages that due to the fact that the ultrasonic wave generators are additionally arranged in an original crude oil delivery pipe and replace a corresponding boiler room for heating, the construction cost and the maintenance cost are reduced; in addition, each sound wave oscillation cavity is formed in the periphery of the corresponding ultrasonic wave generator, and therefore the improvement on the rheological property of the crude oil which is prone to coagulation and high in viscosity is enhanced.
Description
Technical field
The utility model relates to a kind of heavy oil conveying pipeline, particularly a kind of ultrasonic resonance chamber heavy oil conveying pipeline.
Background technique
The high viscosity of viscous crude has directly affected the cost and benefit of heavy oil transportation, and the outer defeated very difficulty of special viscous crude of part block, in order to reduce the friction loss of heavy oil transportation pipeline, must take effective viscosity reduction measure.The method of heavy oil transportation mainly contains heating and carries, mixes rare conveying, the conveying of thin fluid ring, emulsion conveying etc. both at home and abroad.Ultrasonic thinning technology is a kind of new technology developing rapidly in recent years.
When the ultrasound of certain frequency passes through liquid, the small complex in liquid is activated.When acoustic pressure is enough large, under sound wave suction function, nuclei of bubbles expands; Under sound wave positive pressure, nuclei of bubbles compression, shows a series of dynamic processes such as vibration, growth, contraction, collapse of nuclei of bubbles.During nuclei of bubbles collapse, at its little space around and the utmost point, in the short time, the local high temperature that produces reaches 10000 ℃, and instantaneous pressure can reach several more than thousand ten thousand barometric pressure even, and be accompanied by the jet that strong shock wave and speed per hour reach 400km left and right, Here it is cavitation phenomenon.Ultrasonic cavitation effect can change crude oil internal structure, and making the large molecular breakdown of part of crude oil is little molecule, and viscosity of crude is reduced.
When ultrasound is propagated in Elastic medium, make amplitude, speed and the acceleration generation notable change of elastic particle.Mechanical vibration effect can be accelerated the relative movement between macromolecular chain that in crude oil, less molecule and inertia are large, makes viscous crude shear shinning, thereby plays viscosity reduction effect.
When ultrasound is propagated in crude oil, crude oil Absorption of Medium acoustic energy changes into heat energy; At the separating surface place of different medium, boundary friction produces heat; Cavitation produces heat when bubble collapses, and the temperature of crude oil is raise, thereby make reducing crude oil viscosity.More than analyze and show, ul-trasonic irradiation can reduce former oil viscosity, thereby reduces the flow resistance of crude oil, improves the lifting of viscous crude and carries effect.And at present, do not apply the heavy oil conveying pipeline of this technology.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of ultrasonic resonance chamber heavy oil conveying pipeline is provided, and reduces the flow resistance of crude oil, improves the lifting of viscous crude and carries effect.
Its technological scheme is: comprise outer wall, inner layer tube wall, vibration chamber, ultrasonic generator, vacuum insulating region, the outside of described inner layer tube wall is provided with outer wall, between inner layer tube wall and outer wall, be provided with many group ultrasonic generators, a side at each ultrasonic generator is provided with vacuum insulating region, and form vibration chamber in the outside of ultrasonic generator, make ultrasound after amplifying, act on the crude oil in oil-piping in vibration chamber.
Above-mentioned outer wall adopts the protective tube of toughened glass pipe or reinforced plastics material.
The beneficial effects of the utility model are: by installing ultrasonic generator additional in the carried of crude oil pipeline original, replace the heating of corresponding boiler room, reduce construction cost and maintenance cost; Meanwhile, at corresponding ultrasonic generator, sonication chamber is set around, makes to produce resonance, strengthen the improvement of the rheological equationm of state of the solidifying highly viscous crude of commute; In addition, also in pipeline periphery, vacuum insulating chamber is set, guarantees that ultrasound can not produce harm to peripheral facilities.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: outer wall 1, inner layer tube wall 2, vibration chamber 3, ultrasonic generator 4, vacuum insulating region 5.
Embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises outer wall 1, inner layer tube wall 2, vibration chamber 3, ultrasonic generator 4, vacuum insulating region 5, the outside of described inner layer tube wall 2 is provided with outer wall 1, between inner layer tube wall 2 and outer wall 1, be provided with many group ultrasonic generators 4, a side at each ultrasonic generator 4 is provided with vacuum insulating region 5, and form vibration chamber 3 in the outside of ultrasonic generator 4, make ultrasound after amplifying, act on the crude oil in oil-piping in vibration chamber 3.
Wherein, outer wall 1 adopts the protective tube of toughened glass pipe or reinforced plastics material, and this is designed with and helps to reduce the corrosion failure that crude oil pipeline long term exposure occurs in air time; Inner layer tube wall is common oil transport pipeline, and inwall has undercoating, and undercoating physicochemical properties are stable.
The device that vacuum insulating region 5 arranges as preventing ultrasound to run off, because sound wave can not be propagated in a vacuum, so reduced in theory hyperacoustic infringement that leaks personnel and equipment are caused.
