Abstract
The utility model provides a hydrogenating reactor with selfabsorbing circulation and deep diffusion type, suitable for a tank style hydrogenation job and hydrogenation process with a small lot size and intermittent operation in a medicine industry and the other chemical industries. Material is three-phase system of gas, liquid and solid. Alternate contact face is increased. The key is to promote chemical reaction and strengthen mass transfer process. The combined agitating reactor of the prior art is not ideal. A selfabsorbing circulation deep diffusion type stirrer which is composed of an impeller and a negative-pressure pipe is designed in the hydrogenation reactor of the utility model. The problem of homogeneous mixing of three-phase of the gas, the liquid and the solid is solved better. Energy consumption is low. Hydrogen gas utilizing rate is high. Catalysts consumption is less.
Description
The present invention relates to the particularly a kind of self-priming circulation deep layer distributing hydrogenation reactor in the medical industry of organic synthesis industry.
In the medical industry, the characteristics of chemical synthetic drug production are, lot volume in material input is few, great majority are intermittent operation, its hydrogenation reactor, the tower flow reactor of can not image-stone oiling worker, adopting during catalytic hydrogenation in the industry such as grease or chemical fertilizer, and adopt mainly by tank body, agitator and advance the tank reactor that the hydrogen pipe is formed.
Because in the hydrogenation process, material be gas-liquid-solid three-phase system (gas (hydrogen)-liquid (reaction mass and solvent thereof) Gu-(catalyst, as platinum (Pt), palladium (Pa), nickel (Ni) etc.), gas, solid two-phase are fully disperseed in liquid phase, increase alternate contact surface, to promote chemical reaction and to strengthen mass transport process, be the main difficult problem of pot type hydrogenation reactor.Solving the means of this difficult problem, can only be to select suitable agitator for use, improves stirring efficiency.
Hydrogenation reactor, the external simple turbine stirrers that adopt more, hydrogen ingress pipe enters below the liquid level, when the hydrogen bubbling enters liquid phase, disperse hydrogen by turbine stirring, because hydrogen time of staying in liquid phase is of short duration, can not be recycling, so once logical H-H reaction rate is lower.
Hydrogenation reactor, the domestic combined type agitators that adopt more, promptly shaft is equipped with the impeller of anchor formula, slurry formula, various ways such as turbine slurry formula, guided turbine and closed turbine from bottom to top.Hydrogen ingress pipe only reaches more than liquid level, and during reaction, catalyst is stirred by the bottom anchor agitator, upwards seethe, be suspended in the liquid phase, when hydrogen arrives liquid level, " be pressed into " liquid phase by turbine, other pattern agitator by the intermediate level mixes again.Production practices prove that the hydrogenation reactor of the combined type agitator of prior art, hydrogenation efficiency are better slightly than the hydrogenation reactor of simple turbine agitator.But it belongs to surperficial Puffer-type after all, and hydrogen " is pressed into " whole liquid phase region is difficult by turbine, and have that device structure complexity, materials are many, the more high-power shortcoming such as energy consumption height that causes of needs.
Purpose of the present invention will provide a kind of follow-on hydrogenation reduction device exactly, overcomes all deficiencies that exist in the prior art.
Task of the present invention is achieved in that
In the pot type hydrogenation reactor, designed self-priming circulation deep layer distributing agitator, like this, can reach gas-liquid-solid three-phase and mix, hydrogen can be recycling.When jar holds when identical, self-priming circulation deep layer distributing hydrogenation reactor provided by the invention, compound stirring-type hydrogenation reactor than prior art, hydrogenation efficiency obviously improves, hydrogen can be repeatedly in the alternate Infinite Cyclic of solution-air, and agitator itself is simpler than the combined type agitator structure of prior art, and material usage is economized, required power is less, and power consumption is also economized.Make the material of self-priming circulation deep layer distributing agitator of the present invention, can adopt charcoal steel, stainless steel or rare metal such as titanium steel etc., material submits to the purposes needs.
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is that self-priming circulation deep layer is disperseed the structure of hydrogenation reactor and the schematic diagram of duty.
Fig. 2-Fig. 5 is the shape exemplary graph of impeller 2.
Among Fig. 1, take over 1 with exhaust steam on the can body, air intake 10, water takes over 6, cage shoe 5, manhole 8 advances hydrogen pipe 11, discharging opening 12.Be provided with baffle plate 4 in jar, the piece number of baffle plate determines that as required its width with the ratio of reactor tank diameter is: 0.06～0.1:1, can be not baffled yet, probe tube 9, the lower end of shaft 7 are fixed with the impeller 2 of self-priming circulation deep layer distributing agitator, and negative pressure pipe 3 is enclosed within on the shaft 7, its lower end and impeller 2 are assembled into an overall structure, run-in synchronism, its upper end open are more than the reactant liquor liquid level, because rational in infrastructure herein, catalyst has been avoided " grinding " problem, consumes corresponding reduction.
The shape of adaptable impeller 2 has been enumerated several examples, and Fig. 2 is six curved leaves, and Fig. 3 is a triangle, and Fig. 4 is a prismatic, and Fig. 5 is four tubular.
Impeller 2 of the present invention, its shape can be two angie types, trigonometric expression, four angie types, five angie types, hexagonal formula, heptangle formula, octet formula, nine angie types, i.e. any in two angie type to the nine angie type scopes.
The wheel blade of impeller 2 of the present invention can be straight leaf, angle leaf, also can be curved leaf.
Self-priming circulation deep layer provided by the invention disperses the working condition of hydrogenation reactor as follows:
After having added material and catalyst in the reactor, conventional displacement, logical hydrogen, the shaft of rotation drives the agitator arm 2 of its lower end at a high speed, and when impeller distal wire speed reached 5～7m/s, the impeller rear side formed " hole " and causes negative pressure, by the passage between negative pressure pipe and the shaft, hydrogen (from logical hydrogen pipe) on the reaction tank level is pumped to the liquid phase depths clashes through paddle again, make hydrogen form countless micro-bubbles, be dispersed in together in the whole liquid phase with catalyst.
When the remaining hydrogen of reaction is overflowed in liquid phase when returning liquid level, again with the hydrogen of new feeding by negative suction pipe once more, enter the liquid phase depths, hydrogen is alternate in solution-air, so move in circles, until arriving reaction end, when stopping logical hydrogen till.
