The present invention relates to bubbling stirred autoclave technical field.
Background technology
In Chemical Manufacture, for making the abundant hybrid reaction of liquid-solid phase material, in reactor, can stir in bubbling mode.The bubbling agitating device Chinese patent CN201887067U of prior art discloses bubbling stirring-type liquid-replenishing device with texturing tank, its complex structure, adopt the bubbling form of the venthole in square tube, air-flow is realized the stirring to material in retort with the venthole of horizontal direction vertically upward by square tube, this kind of agitating device, the deficiency existing, first venthole vertically upward, initial velocity direction is vertically upward, the ascent rate of bubble is also vertically upward, after bubble disengagement venthole, hightail reaction interface with the synthetic upward velocity direction of two speed, stirring efficiency is low, therefore power consumption is large, it two easily forms and stirs dead angle in reactor bottom, it three is multiple bubbling mixing components, is placed in bottom, and complex structure easily stops up, is unfavorable for to clean.Application number is that 200910252129.0 Chinese patent is simple in structure, clean and maintenance is convenient, but exist equally reactor bottom to be prone to stir dead angle and initial velocity direction is vertically upward, the ascent rate of bubble is also vertically upward, after bubble disengagement venthole, hightail reaction interface, the defect that power consumption is large, stirring efficiency is low with the synthetic upward velocity direction of two speed.
Summary of the invention
The defect existing in order to overcome above-mentioned prior art, the object of the present invention is to provide a kind of can directly act on reactor bottom deposition solid phase, stirring efficiency is high, power consumption is low, without stir dead angle, simple in structure, be easy to install, simple to operate, not susceptible to plugging bubbling stirred autoclave.
The technical solution used in the present invention comprises reactor 1, circular arc back taper bubbler 2, intake valve 3, air inlet pipe 4, outlet valve 5, discharge nozzle 6, bubble holes 21, interior tightening screw 22, interior sealing gasket 23, external seal pad 24, outer tightening screw 25, common fine thread 26, taper pipe thread 27, it is characterized in that reactor 1 lower central place is equipped with circular arc back taper bubbler 2, circular arc back taper bubbler 2 connects air inlet pipe 4, and intake valve 3 is housed in air inlet pipe 4; Reactor 1 bottom connects discharge nozzle 6, and outlet valve 5 is housed on discharge nozzle 6; Described circular arc back taper bubbler is characterized in that outer surface is similar to circular arc reverse taper, and back taper bottom surface is the arc surface of evagination, and back taper side is inside recessed cambered surface, has the bubble holes 21 of N equal aperture on the inner concave arc surface of back taper side.
Described circular arc back taper bubbler 2 back taper bottom surfaces are excessively connected with side circular arc.
The opening direction of N bubble holes 21 on described circular arc back taper bubbler 2 changes with the inner concave arc surface of back taper side, by laterally downward gradually.
In described air inlet pipe 4, there is common fine thread 26 to be connected with reactor by interior tightening screw 22, interior sealing gasket 23, external seal pad 24, outer tightening screw 25 with taper pipe thread 27.
Described circular arc back taper bubbler 2 bottom surface diameters and reactor diameter ratio are 1: 4.
Beneficial effect
The bubble bloating by the bubble holes 21 on circular arc back taper bubbler 2 is realized the stirring to liquid-solid material in reactor, bubble is because of the opening direction difference of the bubble holes 21 on circular arc back taper bubbler 2, the bubble initial velocity direction that different bubble holes overflow is from down to up by laterally downward direction transition gradually, directly act on reactor bottom, do not stay and stir dead angle;
Bubble holes is in the bottom of circular arc reverse taper, and bubble first oliquely downward moves, and is subject to the resistance of the material that reactor is stirred, and speed slows down gradually, and finally moved upward by the effect of material buoyancy.Stirring bubble running orbit is that circuit is long, continues the stirring action time long, and stirring efficiency is high, can reduce power consumption.
Circular arc back taper bubbler 2 outer surfaces are circular arc streamlined, and the flow resistance of convection cell is little;
Bubble holes 21 openings are positioned at circular arc back taper bubbler 2 belows, are difficult for being stopped up by solid material;
Circular arc back taper bubbler 2 volume urine are in the cleaning to reactor;
Circular arc back taper bubbler 2 is simple in structure, is convenient to install and change, with low cost.
