Description
Technical field
The present invention relates to a kind of chemical production device, be specifically related to be replace mechanical agitation autoclave blender without mixing stirring device.
Technical background
Thereby mixing is to make two or more different materials mutually disperse to reach each other uniform process.Common married operation mostly is mechanical agitation.Also have and adopt airflow stirring or jet agitation realization to mix, but compare with mechanical agitation, use less.Make material realize that the device that mixes claims to stir the autoclave blender by mechanical agitation.It is wide to stir autoclave mixer application scope, in chemical industry, no matter be large industrial chemicals or fine chemicals production, all using in large quantities the mechanical agitation married operation, other is also all using the mechanical agitation married operation widely such as industries such as oil, medicine, agricultural chemicals, dyestuff, paint, chemical fertilizer.Stirring can impel the material disturbance, realizes that the material in the blender evenly distributes, and reaches the purpose of strengthening heat and mass transport.
The structure that stirs the autoclave blender comprises kettle, end socket, adapter, transmission device, agitating device, packing seal or mechanically-sealing apparatus and various annex.Use more agitating device that flat slurry formula, push type, frame, anchor formula, three leaf swept-backs, turbine type etc. are arranged.
Although stirring the autoclave blender uses with a long history, the application scenario is extensive, but stir the autoclave blender obvious deficiency is still arranged,, sealing device stressed greatly be easy to high such as equipment manufacturing cost and energy consumption damaged and the appearance leakage, change sealing device and cause reducing effective production time, temperature of charge and CONCENTRATION DISTRIBUTION are unequal in the still.
It is very significant that a kind of new and effective mixing arrangement that can overcome to greatest extent present stirring autoclave blender deficiency is provided.
Summary of the invention
The invention provides a kind of without mixing stirring device
,Rely on fluid dynamic energy to realize mixing without mixing stirring device, be widely used in the various occasions that need mixing of materials.Apparatus cost is low, consuming little energy, good mixing effect, and the use procedure maintenance less, effective production time is long.
Technical scheme of the present invention is:
Without mixing stirring device, comprise mixing kettle, circulating pump, pipeloop, disturbed flow pipe, connecting line and various pipe fitting, annex.Be installed with inlet fluid distributor, outlet fluid conduction pipe and flow apron in the mixing kettle.Comprise that material to be mixed is in proportion before circulating pump or the disturbed flow pipe front access device, mix through the mobile limit of flow-disturbing tube edge, enter in the mixing kettle through the inlet fluid distributor, flow to the mixing kettle center under the flow apron effect, the segment fluid flow in the mixing kettle flows out mixing kettle through outlet fluid conduction pipe and participates in circulation; Material to be mixed in proportion before circulating pump or disturbed flow pipe advance into the disturbed flow pipe inner edge limit of flowing and mix, enter mixing kettle through the inlet fluid distributor again, without Fluid Circulation; Or one or more materials to be mixed add in the mixing kettle in advance, start circulating pump, another kind of or multiple material to be mixed uses two or more materials to realize mixing in disturbed flow pipe and mixing kettle before circulating pump or the disturbed flow pipe front access device under the acting in conjunction of inlet fluid distributor, outlet fluid conduction pipe and flow apron; Or in the material adding mixing kettle to be mixed, starting circulating pump, material realizes mixing or keeping mixing under disturbed flow pipe, inlet fluid distributor, outlet fluid conduction pipe, flow apron acting in conjunction.
Above-mentioned without mixing stirring device, its pipeloop partly or entirely is disturbed flow pipe, and disturbed flow pipe is to be provided with chemical filler in blank pipe or the pipe or convection cell plays the hybrid element of perturbation action, or adopts commercially available static mixer as disturbed flow pipe.Disturbed flow pipe single or many unite use.
Above-mentioned without mixing stirring device, the inlet fluid distributor that sets firmly in its mixing kettle consists of by having hole and the curved tube that is interconnected and straight tube, and curved tube and straight tube be vertical, be parallel to the mixing kettle wall or become the angle of inclination to arrange with wall; The outlet fluid conduction pipe that sets firmly in its mixing kettle is flat nozzle or set in nozzle, and when adopting set in nozzle, the insertion still had for the fluid that is in differing heights place in the still and enters its interior hole in inner minute; The flow apron that sets firmly in its mixing kettle is flat board or bent plate, and the barrel of flow apron and mixing kettle tilts or is arranged vertically.
Above-mentioned without mixing stirring device, when being used for the occasion of heat transmission is arranged, its mixing kettle, pipeloop partly or entirely are provided with chuck.
The present invention has following advantage:
1. the present invention both can be used for continuous production, can be used for again Batch Process;
2. low, the consuming little energy of mixing arrangement equipment manufacturing cost that proposes of the present invention, mixed effect obviously is better than mechanical agitation and mixes;
3. the mixing arrangement heat transfer area of the present invention's proposition is large, and heat transfer efficiency is high;
4. machinery-free stirs in the mixing arrangement still of the present invention's proposition, need not to keep in repair or change mechanical seal or the packing seal that traditional stirred tank adopts, and can increase effective production time;
5. in proportion charging of material to be mixed, when being used for course of reaction, the material that participates in reaction can be realized rapid mixing through disturbed flow pipe, can overcome the fatal shortcoming of the interior CONCENTRATION DISTRIBUTION inequality of traditional mechanical agitation mixing kettle and hot-spot.
