Description

A kind of impact flow reactor for reactive liquid solution
Technical field
The present invention relates to a kind of reactors for oil and chemical production field, and in particular to one kind being used for reactive liquid solution With propeller from driving impact flow reactor.
Background technology
In oil and Chemical Manufacture, there are many processes to be carried out in liquid phase or using liquid as the phase of continuous phase under the conditions of, Most of these processes further relate to chemically react.Since liquid belongs to condensed state system, molecular motion is extremely limited.It is right In the process carried out on molecular scale, microcosmic troubled water becomes extremely important.
Percussion flow is to realize a kind of highly effective method quickly mixed.It is hit in opposite directions using two strands of high-velocity fluids, The impingement region for forming a high turbulence in the reactor, can effectively reduce the external drag in transmittance process, promote mixing, Enhancing mass and heat transfer.Impact flow reactor is widely used for the chemical processes such as absorbing, mix, conduct heat, crystallize.
Since the 1990s, the research in percussion flow field is obviously turned to liquid continuous phase percussion flow(Liquid- Continuous Impinging Streams, LIS)Attach most importance to.Patent CN 100364656C are arranged two in reactor shell After liquid flows separately through both sides guide shell by the driving effect of pump, opposite hit occurs at center for the guide shell of a face. This reactor is although simple in structure, but has only focused on the impact effects of both ends guide shell fluid, after not considering liquid knockout Flow condition in the reactor, be easy to causeing reactor both sides, there are dead zones.If in two shock fluids, there are solid catalysis Agent then be easy to cause catalyst sedimentation, is detained, directly affects reaction depth and product quality.
Propeller is arranged in 102989404 A of patent CN in guide shell, to react using the driving effect of two propellers Liquid is hit at center in device, while using the effect of guide shell and flow deflector, solving the mixing outside impingement region Problem.But propeller needs power drive, it is therefore desirable to which peripheral hardware motor increases the overall cost of reactor;In addition, installation spiral shell The motor shaft of rotation paddle needs to install shaft seal structure on the reactor wall, and long-term operating easily causes damage, influences the long week of reactor Phase runs.
Invention content
The technical problem to be solved in the present invention is to provide a kind of impact flow reactor for reactive liquid solution, it can not only Enough strengthen the impact effects of percussion flow, and may be implemented the outer liquid of impingement region it is efficient, be sufficiently mixed, and overcome band spiral The axle envelope problem of paddle impact flow reactor has advantage simple in structure, reliable for operation.
Used technical solution is the present invention to solve above-mentioned technical problem:
A kind of impact flow reactor for reactive liquid solution, including reactor shell, along level side in reactor enclosure body To the guide shell of two faces of setting, each guide shell includes inner barrel and outer barrel, in outer barrel close to the one of impingement area End is fixedly connected with from propeller runner.Described is an integral structure from propeller runner comprising cover cylinder, ring flat-plate, blade and central plate Four parts.Cover cylinder is connected with ring flat-plate, and the two is used for conducting fluid, and ring flat-plate is connected with outer barrel;Blade is fixed on ring flat-plate, and is led Flow cartridge axially forms an angle, and as fluid flows therethrough, does work to it, is rotated under thrust;Central plate is for reducing Actual internal area, enhancing spin power.
