Abstract
The invention discloses a continuous rotatable jet type static mixer which comprises an outer pipe and an inner pipe which are concentrically arranged with each other, wherein a connecting flange is arranged at each of two ends of the outer pipe; a pipe plug is arranged at one end of the inner pipe, and a feed port is arranged at the other end of the inner pipe; the inner pipe is internally formed into a low-viscosity fluid feed cavity; an inner pipe clapboard and an outer pipe clapboard are respectively arranged at the end heads of the inner pipe and the outer pipe; a mixing chamber is formed between the inner pipe and the outer pipe and is internally provided with a spiral flow deflector which leads mixed liquid to rotatablely flow in a flow channel of a blade; the inner pipe is evenly provided with a plurality of jet holes which lead low-viscosity fluid to enter into the mixing chamber; and the outer pipe is provided with a feed port of high-viscosity fluid polymer. Due to the technical scheme, the continuous rotatable jet type static mixer breaks down the condition that the work mode of the existing mixing unit of a conventional static mixer depends on continuous mechanical cutting, the mechanical cutting and degrading of the polymer are reduced, the spreading function of the two-phase fluid during joining is taken as the main mixing method, and the mixing effect is improved aided by the rotatable stirring movement of the fluid.
Description
Technical field
The present invention relates to static mixer, be specifically related to a kind of continuous rotatable jet type static mixer, be used for oilfield polymer flooding development field a kind of polymer (PAM) used and mix with the even of water, also be applicable to the fluid mixing process of the industries such as petrochemical industry, environmental protection, medicine, food.
Background technology
In the oilfield polymer flooding development process, in order to keep the water injection rate balance, improve recovery ratio, avoid oil-polluted water to efflux, adopted the high molecular polymer technology of reservoir sweep, the concentration of this polymer reaches 5000mg/l, viscosity reaches 3000～4000mPa.s, uses this polymer to need it is mixed according to a certain percentage with water before; At present the static mixer of oilfield injection have SMV type, SMX type, SML type, KENICS type and KENICS type and the SMX type combined etc.
These motionless mixers are mainly used in chemical industry, are used for emulsification and extractive reaction, and these blenders require high shear, are mostly pure mechanical partition types.And in tertiary oil recovery, polymer mother liquor and dilution water mixed has its particularity, at first requires to reduce the shear degradation to polymer solution as far as possible, improves the viscosity number of the material of mixer outlet; Secondly, the mobility ratio of two-phase fluid is large, and the mixed effect of simple Blending Way with cutting apart, recombinate, confluxing is bad.
Summary of the invention
In order to overcome existing static mixer to the deficiency that shear degradation is large, mixed effect is poor of polymer solution, the invention provides a kind of continuous rotatable jet type static mixer, this static mixer is little to depolymerization, good mixing effect, can be applicable to the static mixing of high-viscosity polymer and water.
To achieve these goals, the present invention adopts following technical scheme:
a kind of continuous rotatable jet type static mixer, it is characterized in that, the outer tube and the inner tube that comprise concentric setting, described outer tube two ends arrange respectively an adpting flange, described inner tube one end is provided with a pipe plug, the other end is charging aperture, its inner feed cavity that forms the low-viscosity fluid, described inner tube and outer tube are provided with an inner and outer pipes dividing plate in the end, form hybrid chamber between inner and outer pipes, be provided with the spiral flow deflector that forces mixed liquor rotational flow in blade passage in hybrid chamber, evenly have some spray-holes that make the low-viscosity fluid enter hybrid chamber on described inner tube, described outer tube is provided with the charging aperture of high viscosity fluid.
Further, the charging aperture on described outer tube is the tangential admission mouth.
Further, the spray-hole center line on described inner tube and blender axis angle angular range are 30 °～90 °.
Owing to having adopted technique scheme, the present invention is by arranging hybrid chamber, break mixed cell in the past and depended merely on the working method that continuous machinery is cut apart, improved the mixing efficiency of blender, reduced mixing length, and static mixer of the present invention can reduce blender to the machine cuts of polymer molecular chain without any projection or sharp corner angle; By spiral flow deflector is set in hybrid chamber, make mixed liquor produce rotation, dispersion under the effect of spiral flow deflector, mix, increased the touch opportunity of high viscosity fluid and low-viscosity fluid, reached the mixed uniformly purpose of promotion; The spray-hole that evenly is arranged on inner wall tube makes the low-viscosity fluid produce Slice by slice cutting, thereby injects dispersedly hybrid chamber, has improved the convection current mixed effect; The setting of tangential admission mouth enters high viscosity fluid to produce after hybrid chamber and rotatablely moves, and is conducive to mixing of high viscosity fluid and the low-viscosity fluid that enters from inner tube; In addition, the mixed liquor in the present invention out rotates afterwards from blender, and mixed liquor still can further mix by the suitable segment distance after blender.
