Description
Technical field
The present invention relates to a kind of heavy oil modification device, particularly relate to a kind of equipment of Hydrodynamic Cavitation for heavy oil modification and system.
Background technology
Heavy oil typically refers to density and is greater than 0.93g/cm
3, under normal pressure, boiling point is higher than the crude oil of 350 DEG C.Due to containing more long-chain macromolecule, resin and asphalt, heavy oil viscosity is comparatively large, and poor fluidity, exists disadvantageous effect to carried of crude oil, therefore needs to carry out the modifying process such as viscosity reduction to heavy oil.At present, conventional both at home and abroad heavy oil viscosity reducing process can be divided into Physical and the large class of chemical method two.
Physics viscosity reducing process mainly comprises heating, viscosity reducing method, thin oil blending visbreaking method, low viscosity pendular ring viscosity reduction method etc.Heating visbreaking method mainly makes heavy oil system obtain enough energy to destroy the macromolecular π key of colloid, bituminous matter etc. in heavy oil and hydrogen bond by heating, thus the viscosity of heavy oil is reduced, however its energy consumption is high, stopped flow injection analysis time easily occur to coagulate event of running affairs; Lightweight oil and viscous crude are mainly carried out blending by mixing light oil visbreaking method, and reach the defeated requirement of pipe to make the viscosity of mixing rare rear viscous crude reduce, although it can realize not heated transportation substantially, but cost is high, the limited source of thin oil; Low viscosity pendular ring viscosity reduction method is incorporating low viscosity immiscible liquid (such as water) in viscous crude, it is made to be surrounded by low viscosity liquid by controlling viscous crude flow velocity, thus reduction resistance to flow, but the method liquid flow pattern stability is very poor, be easy to suffer to destroy formed profit mix to.
Chemical viscosity reduction method mainly comprises chemical additive viscosity reduction method, microorganism viscosity reduction method, hydrothermal catalytic cracking method, viscosity breaking method etc.Chemical additive viscosity reduction method is under Action of Surfactant, make the Water in Oil emulsion of viscous crude be transformed into the milk sap of oil-in-water-type, thus reduce the viscosity of oil-water mixture, but the method Produced Liquid sewage is difficult, various breaking dehydrating method remains in some problems; Microorganism viscosity reduction method utilizes microbial technology to carry out biological degradation to heavy components such as the colloid in crude oil, bituminous matters, but microorganism not easily survives under some critical conditions, and screen suitable microorganism species also relative difficulty; Hydrothermal catalytic cracking method mainly makes the sulfide linkage cracking in viscous crude in sulfocompound thus viscosity is reduced, but it also needs at high temperature to carry out, and energy consumption is higher; Viscosity breaking method is that heavy oil is reduced its condensation point, viscosity to meet some specific upgrading requirement by either shallow thermally splitting, but its complex process, temperature of reaction and pressure are high.
Hydrodynamic cavitation refers to liquid in flow process because actual internal area reduction, linear rate of flow rising, pressure reduce and causes partially liq to be vaporized, by recovering sectional area in flowing subsequently, liquid flow velocity slows down, pressure increase, bubble is crumbled and fall, thus produces the extreme environments such as high temperature, high pressure, microjet in local.Although this extreme environment can make macromole cracking, but the saturated vapor pressure of heavy oil is lower, and heavy oil be made to vaporize, and required velocity of flow is large, and heavy oil viscosity is very large, therefore realizes cavitation quite difficult.At present, also under lesser temps (less than 70 DEG C), heavy oil generation Hydrodynamic cavitation is not made to carry out the relative unit of upgrading heavy oil.
Summary of the invention
The invention provides a kind of equipment of Hydrodynamic Cavitation for heavy oil modification and system, can realize making heavy oil generation Hydrodynamic cavitation carry out upgrading heavy oil at a lower temperature, and good upgrading and viscosity reducing effect can be obtained.
A kind of equipment of Hydrodynamic Cavitation for heavy oil modification provided by the invention, comprise the heavy oil entrance, trunnion section and the stable section that set gradually, the circulation area of described trunnion section is all less than the circulation area of described heavy oil entrance inlet end and described stable section inlet end, described trunnion section is connected with described stable section with described heavy oil entrance respectively and is axially communicated with, and in described trunnion section, radial direction is provided with the auxiliary agent entrance be communicated with described trunnion section.
The structure of counterweight oil-in of the present invention section, trunnion section and stable section does not do strict restriction, but is understandable that, each section all has axial through hole, and the through hole of each section is axially communicated with, and each through hole can coaxially be arranged.Each section of this equipment of Hydrodynamic Cavitation can be one-body molded, also can pass through mounting block (such as bolt and nut etc.) in addition and achieve a fixed connection between each section.In concrete scheme of the present invention, each section is all cylindrically, thus advantageously in implementing and making the heavy oil generation Hydrodynamic cavitation through this equipment of Hydrodynamic Cavitation.
According to equipment of Hydrodynamic Cavitation provided by the invention, the internal diameter of the inlet end of described heavy oil entrance is 15 ~ 50mm, and the ratio between the internal diameter of the internal diameter of the inlet end of described heavy oil entrance and described trunnion section is 1:(0.1 ~ 0.5), the ratio between the internal diameter of the inlet end of described stable section and the internal diameter of described trunnion section is 1:(0.1 ~ 0.5).In the present invention, inlet end refers to one end that in each section, heavy oil flows into, and exit end refers to one end that in each section, heavy oil flows out; Further, the internal diameter of stable section inlet end can be identical or close with the internal diameter of heavy oil entrance inlet end.When each section of through hole cross section is circular, described internal diameter refers to the diameter of correspondent section through hole.
Further, the ratio between the internal diameter of described trunnion section and the internal diameter of described auxiliary agent entrance is 1:(0.2 ~ 0.5).This scope both can realize the suction helping cavitation agent, can not reduce simultaneously cause disadvantageous effect to the pressure of trunnion section.
According to equipment of Hydrodynamic Cavitation provided by the invention, the ratio between the length of described heavy oil entrance and the internal diameter of its inlet end is (1 ~ 3): 1.Further, the ratio between the length of described trunnion section and its internal diameter is (1 ~ 2.5): 1.Further, the ratio between the internal diameter of the length of described stable section and the inlet end of described heavy oil entrance is (3 ~ 5): 1.The equipment of Hydrodynamic Cavitation with this parameter is conducive to realizing preferably Hydrodynamic cavitation effect, and reaches good upgrading and viscosity reducing effect.
