Gas-liquid reaction apparatus of the present utility model comprises: aeration impeller 1, paddle 2, hollow shaft 3, reactor 4, swivel joint 5, shaft coupling 6, air inlet pipe 7, seal member 8 and mixer drive 9.Wherein: swivel joint 5 is positioned at the reactor inner and upper, on perforate is arranged, connect air inlet pipe; Aeration impeller 1 is positioned at the below of paddle 2.
Vertical pivot aeration wheel is sewage treatment industry oxygenation parts commonly used, aeration wheel commonly used has pump type impeller, inversed umbrella type impeller, plate impeller etc., aeration impeller 1 of the present invention improves on this basis and obtains, disk 12 and lower disc 13 on increasing on the aeration wheel 11, last disk 12 centers have the axially extending bore that cooperates with hollow shaft 3, lower disc 13 (atresia) directly is welded on the aeration wheel 11, prevents that high-speed liquid from dishing out from the bottom.Paddle the latter half at aeration wheel 11, can also increase the awl tube 14 that lower edge is connected with lower disc 13, high-speed liquid is dished out along paddle top, and the upper limb of awl tube 14 determines according to the impelling route of required high-speed liquid, can select aeration impeller 1 the paddle height 20%～80%.Last disk 12, lower disc 13 (with awl tube 14) acting in conjunction, the assurance high-speed liquid is dished out along specific route, forms required big negative pressure.
According to required vacuum magnitude, the physical property of agitated liquid, paddle 2 can be selected 1-12 sheet palintrope leaf, antecurvature leaf, straight leaf, paddle that tiltedly leaf etc. can various realization negative pressure, preferred 2-6 sheet for use.
Hollow shaft 3 is connected with mixer drive 6 by swivel joint 5, hollow shaft perforate arises from swivel joint 5 (top or lateral opening), is communicated with air inlet pipe 7, transmits negative pressure, in reacting gas sucting reaction liquid, hollow shaft 3 also can be used as the top discharge passage.
The utility model utilizes aeration impeller 1 to stir the negative pressure that forms, by hollow shaft 3, the perforate of swivel joint 5 and hollow shaft 3, reacting gas is sucked in the liquid phase, and utilize the aeration peptizaiton of aeration wheel 11, the gas breaking that sucks is become very tiny bubble, improve the contact area of gas-liquid two-phase, and the effect by last lower disc (and awl tube), gas is dished out fast along particular course, improve reaction efficiency; Utilize the paddle 2 on upper strata to stir simultaneously to form suction eddy when rotating at a high speed again the gas of going up sheaf space in the reactor to be drawn in the liquid, pass through Gas-Liquid Absorption, mass transfer again, gaseous phase materials improves the reaction speed with liquid greatly under stirring action.The utility model need not the compressor charging, be particularly useful for deep-etchings such as halogen gas or hydrogen sulfide, hypertoxic gas gas-liquid (Gu) reaction.
Air inlet pipe directly is connected on the swivel joint 5 of shaft 3, therefore motor, reductor etc. there is not the restriction of use, general common hollow shaft is to stretch out from the reductor top, therefore can only use general packing seal, mechanical seal, reductor also can only use modes such as gear reduction unit, worm-gear speed reducer or belt pulley, and (promptly axle must be stretched from the top of reductor or belt pulley, therefore motor can not with reductor on an axis), and this form can be used the forms such as magnetic seal of zero leakage requirement especially.When the utility model reverses at motor, can form malleation in the bottom of paddle, can be with the liquid dispensing apparatus of inside reactor.Be particularly suitable for the mode of production of the continuous fluid of continuous feed liquor that can't bottom discharge because of condition restriction such as mode of heatings.
The utility model is specially adapted to that severe toxicity is arranged in the chemical industry, the gas-liquid that severe corrosive gas participates in (Gu) reaction, its advantage is:
1) omitted the gas feed device, in particular for severe corrosive, the device of hypertoxicity gas feed has reduced investment and maintenance cost;
2) increase gas-liquid (Gu) reaction efficiency, improved output, reduced production cost;
3) magnetic seal is adopted in sealing, prevents that poisonous gas from leaking, and realizes safety in production.
