Description
Technical field
The utility model relates to field of chemical engineering, refers in particular to a kind of multistage slowly-releasing gas diffusion shell that is used for the heterogeneous physical and chemical reaction of all kinds of solution-airs.
Background technology
In the heterogeneous physical and chemical reaction liquid of solution-air, inflate, gas or some component wherein are dispersed or dissolved in the liquid phase, generally realize by gaseous diffuser.Diffusion shell is as the important component part of gaseous diffuser, and its 26S Proteasome Structure and Function plays key effect to gas diffusion dissolution effect.Traditional diffusion shell is not obvious to the shear action of bubble, and it is shorter that bubble is pulled the holdup time, and the bubble release areas is limited to the diffusion shell outer.Occurred at present the diffusion shell of improved increase diffusion term yet, enlarged diffusion zone, but still had following defective: the room and time that bubble hit is sheared does not have corresponding increase, and the diffuser edge is simple in structure, and the bubble release areas is limited to the diffusion shell outer.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, provide a kind of and shear probability, the directly related rule of bubble release uniformity according to gas diffusion dissolution effect and bubble hit, a kind of multistage slowly-releasing gas diffusion shell that proposes and develop on the basis of existing diffusion shell can be widely used in chemical reaction gas diffusion, aeration in sewage treatment and the water body oxygenating process.
The purpose of this utility model is achieved in that the utility model comprises curved surface diffusion disc, flow channels, pawl, diffusion disc connected body, diffusion disc reinforcement, be characterized in: the curved surface diffusion disc, it can be one, or superpose at vertical direction more than two, the diameter difference of adjacent two dishes, adjacent two dishes are 0.05-0.8 in the vertical direction spacing with dish diameter ratio above corresponding, have a plurality of passages on the curved surface diffusion disc, channel shape can be that polygon, (ellipse) are circular, arc or other are irregularly shaped; Passage can seal, and also can open wide; The passage edge is a zigzag or wavy; In diffusion disc circular flat scope, aisle spare and the ratio 0.1-0.8 that coils circular area.
The multistage slowly-releasing gas diffusion of the utility model is covered with following advantage:
1, the utility model is made of curved surface diffusion disc, flow channels, staggered airfoil pawl, diffusion disc connected body, the diffusion disc reinforcement of diffusion disc curved surface outer radial direction multi-turn direction.Curved discs is single or multiple, and curved surface is a corrugated, has flow channels some on the curved discs, and the curved discs below is provided with the staggered airfoil pawl of multi-turn direction.
2, gas enters multistage slowly-releasing diffusion shell bottom through distribution or aerator primary unit, bubble rises at curved surface diffusion disc lower edge curved surface, producing simultaneously shearing, collision and gas-liquid interface under the effect of airfoil pawl upgrades, the part bubble enters another grade diffusion disc step by step through flow channels, make gas shearing, collision, gas-liquid interface renewal probability and diffusion zone greater than single-deck, broken the boundary of edge diffusion, realized the cover diffusion and the three-dimensional diffusion of gas, diffusion uniformity is better.
3, corrugated curved surface has produced interference to bubble along the speed that curved surface rises, and bubble pathway length increases, and the towing holdup time is longer, and the gas dispersion dissolving is more abundant.
4, diffusion disc gas discharges edge employing sawtooth or waveform, and the physical space that makes full use of diffusion disc is disturbed the motion of air bubbles state, increases to shear and gas-liquid interface renewal probability.
