Description
Technical field
The present invention relates to a kind of mixing plant and stirring means thereof, especially a kind of pneumatic stirring equipment and stirring means thereof.
Background technology
Mixing plant is of wide application in industrial production, especially in chemical industry, all chemical changes of chemical enginnering process, that the various materials of participating in reaction are fully mixed into prerequisite, and for physical changes such as heating, cooling, extraction and gas absorption, also must adopt stirring operation just can reach good effect.In three large synthetic materials, mixing plant reactor accounts for 90% of reactor sum.The power consumption in nonferrous metallurgy department wet method workshop approximately has 50% to be used on mixing plant.
Stirring operation divides two kinds: mechanical agitation, airflow stirring.In industrial production, most stirring operation is all mechanical agitation, in take, the mixing plant of low-pressure vertical steel vessel is as main.Mixing plant is comprised of agitating device, shaft seal, agitator tank three parts.Leak, power consumption is large or uncertainty power consumption is churned mechanically subject matter.
Airflow stirring is to utilize gas sparging to pass through liquid level, and liquid is produced to stirring action, or closes bubble population and rise and borrow so-called gas lift effect to promote liquid convection circulation with high density state.Compare with mechanical agitation, bubble is more weak to the stirring of liquid, and the high viscosity liquid of several thousand centipoises is difficult to adapt to.But this stirring movement-less part is to be good at easily to processing the stirring of the corrosive liquids under high temperature, high pressure.
People's waterfall industry commercial explosive factory mixing plant is mainly used in aqueous phase solution preparation, oil-phase solution preparation and the preparation of other trace element solution.Mixing plant divides and has top installation and sidepiece to install two kinds with mounting means, and top is provided with consumed power large (more than 11kW), takes up room greatly, keeps in repair the shortcomings such as inconvenience, and sidepiece is provided with and leaks large shortcoming.Particularly aqueous phase solution and trace element solution are strongly corrosion liquid, must make of stainless steel material, and the easy crystallization of aqueous phase solution, as produced agitating device locking phenomenon for a long time.
Agitated liquid makes it circulating of certain mode occurs, thereby makes the operation that mixing of materials is even or physics, chemical process are accelerated.The application being stirred in industrial production has: the 1. dispersion of bubble in liquid, if air dispersion is in zymotic fluid, to provide sweat required oxygen; 2. the dispersion of drop in liquid immiscible with it, makes emulsion as oil is scattered in water; 3. the suspension of solid particle in liquid adds pigment in to resin solution, to modulate coating; 4. the dissolving of solid particle in liquid, to modulate solution; 5. the mixing of mutually soluble liquids, as make solution dilution, or for the chemical reaction that accelerates to dissolve each other between component etc.In addition, stirring can also be strengthened the heat transfer between liquid and solid wall surface, and material is heated evenly.The method stirring has mechanical agitation and airflow stirring.In tank diameter, the motion of liquid, is divided into overall flow and turbulence pulsation from yardstick.The flow of overall flow is called internal circulating load, adds the degree of mixing well (seeing mixability) that big cycle volume is conducive to improve micromixing.The speed when intensity of turbulence pulsation is left agitator with fluid is relevant, strengthens turbulence pulsation and is conducive to reduce to separate yardstick and segregation intensity.Different processes flows and has different requirements these two kinds.The dispersion of drop, bubble, needs strong turbulence pulsation; The even suspension of solid particle, depends on overall flow.During stirring, energy distribution on flowing at these two kinds, is the major issue in agitator design.When stirring the mixture, the density contrast of two-phase, viscosity and interfacial tension have a significant impact stirring operation.Density contrast and interfacial tension are less, and system is more easy to the dispersion that reaches stable; Viscosity is more unfavorable for forming more greatly good circulating and enough turbulence pulsations, and consumes larger power of agitator.
From stirring technique viewpoint, fluid agitation can be divided into five kinds of basic stirrings to be applied, and each stirring application can be divided into two types according to physical process and chemical process, always has ten kinds of basic stirring application.Each stirs application substantially stirring feature separately, crosses range request and Enlargement Design criterion.
Existing vertical mechanical stirs, stirring motor 17.5kW, and agitating device is suspension type, during because of installation, has certain problem, often occurs shaft obscission in whipping process, impact is produced, and causes waste, has potential safety hazard.
