Abstract
The invention relates to an internal circulation type hydrogenation reaction kettle, relating to the technical field of reaction kettle devices. The internal circulation type hydrogenation reaction kettle comprises a tank body which is of a hollow interlayer structure, wherein a heat preservation sleeve is arranged outside the tank body in a sleeving manner; a feeding hole is formed in an end cover of the tank body; a hydrogenation hole and a sewage discharging hole are formed in the bottom part of the tank body; a discharging hole is formed in the upper half part of the side wall of the tank body; a hollow stirring shaft connected with a stirring motor is suspended in the center of the tank body; a gas sucking hole and gas self-suction type paddles are sequentially fixed on the stirring shaft from top to bottom; heat exchange coil pipes are arranged on the inner wall of the tank body; the hydrogenation hole is connected with an aerator by virtue of a pipeline. The internal circulation type hydrogenation reaction kettle is reasonable in design; hydrogen is mixed and reacted with liquid materials by virtue of internal circulation in the tank body; a gas-liquid mixing effect is improved; the hydrogenation reaction velocity is improved; fewer side reactions are generated.
Description
Technical field
The present invention relates to reactor equipment technical field, especially a kind of internal-circulation type hydrogenation reaction kettle.
Background technology
Along with the continuous progress of science and technology, the products such as the sorbierite needed for the industry such as chemical industry and pharmacy, xylitol, maltitol and furfuryl alcohol are all adopt continously hydrogen adding method to produce, and in the equipment producing this series products, the equipment of core is exactly hydrogenation reaction kettle the most.The hydrogenation reaction of carrying out in hydrogenation reaction kettle traditional at present, reaction time consumption is all long, and applies mechanically increased frequency along with catalyst, time can be more and more longer, side reaction occurs more serious, produces the impurity being much difficult to remove, more easily cause catalyst poisoning, production cost increases.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of structure simple, the reaction time short and hydrogenation reaction kettle of less side reaction.
The technical solution adopted for the present invention to solve the technical problems is: a kind of internal-circulation type hydrogenation reaction kettle, there is the tank body of hollow sandwich structure, the end cap of described tank body is provided with mechanical seal, is provided with stirring motor above mechanical seal, is arranged with muff outside tank body; Described tank body end cap is provided with charging aperture, and tank base is provided with hydrogenation mouth and sewage draining exit, and the sidewall first half of tank body offers discharging opening; Described tank body center suspension has the hollow shaft be connected with stirring motor, and shaft is fixed with from top to bottom successively gas suction inlet and the self-priming blade of gas, inner tank wall is provided with heat exchange coil; Described hydrogenation mouth is connected with aerator by pipeline.
Further, the bottom of described heat exchange coil is provided with cooling water inlet, and the top of heat exchange coil is provided with cooling water outlet.
Further, the self-priming blade of described gas, aerator and heat exchange coil are all positioned at below liquid level when thermal-insulating type hydrogenation reaction kettle works, and gas suction inlet is positioned at more than liquid level.
Further, described discharging opening is provided with butterfly valve.
Further, described stirring motor is cycloidal planetary gear speed reducer.
Operation principle: when hydrogenation reaction starts, hydrogen passes into aerator formation bubble from hydrogenation mouth and mixes with liquid material, the hydrogen having little time to mix floats up to ullage, the self-priming blade of gas is by shaft driven rotary, produce vacuum, by gas suction inlet, the hydrogen of ullage is sucked, produce bubble through hollow shaft by the self-priming blade of gas and spray, with liquid material hybrid reaction.Form hydrogen at tank body Inner eycle by the cooperation of aerator and the self-priming blade of gas, increase gas-liquid mixed effect, improve hydrogenation reaction speed.
The invention has the beneficial effects as follows: the present invention is reasonable in design, be provided with aerator and the self-priming blade of gas, complement each other to form the Inner eycle of hydrogen at tank body, with liquid material hybrid reaction, increase gas-liquid mixed effect, improves hydrogenation reaction speed and side reaction is less.
