Stirring type reacting kettle

Abstract

The invention provides a stirring type reacting kettle which belongs to the technical field of machinery and solves the problems of low producing efficiency and low producing quality both caused by low stirring speed of the existing self-absorption type stirring reactor. The stirring type reacting kettle comprises a closed barrel body provided with a reacting cavity; the upper part of the barrel body is provided with a stirring rod, and the stirring rod is in an axle shape and can be inserted into the barrel body; the upper end of the stirring rod is provided with a motor which can drive the stirring rod to rotate; the bottom end of the stirring rod is fixedly connected with a stirring paddle; the middle part of the stirring rod is sleeved with a gas guiding casing and a plurality of stirring components used for speeding up the flow rate of reacting liquid; the adjacent two stirring components are fixedly connected together, and the inner cavities of the adjacent two stirring components are communicated; the gas guiding casing is arranged at the upper part of the stirring component; and a gas-liquid mixing component with an outlet is arranged between the gas guiding casing and the stirring component and used for the hybrid reaction of the gas and the liquid. The stirring type reacting kettle has the advantage of improving the moving rate of the reacting liquid. After reaction, the reacting liquid can be discharged in time so as to promote the full and rapid reaction of the reacting liquid and the reacting gas, so that the producing efficiency and the producing quality are improved.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a chemical operation reactor, in particular to a stirred reactor. Background technique [0002] The agitator is a device for forced convection and uniform mixing of liquid and gas media. It is widely used in chemical production and realizes large-scale industrial production. Among them, the self-priming agitator uses the principle of the Venturi effect (that is, when the wind blows through the barrier, the air pressure near the port above the leeward side of the barrier is relatively low, thereby generating adsorption and causing the flow of air). The gas on the liquid surface is re-absorbed and dispersed in the liquid phase, which can greatly increase the gas holdup and the contact area of ​​the gas-liquid phase, thereby achieving the purpose of increasing the reaction rate. [0003] For example, Chinese patent literature once disclosed a reactor for direct liquefaction of coal...

AI Technical Summary

Problems solved by technology

[0004] Although the structure of the above-mentioned reaction kettle for direct coal liquefaction realizes the self-priming stirring effect, its self-priming stirring paddle is used to stir the reactants inside the reaction kettle alone, so that the movement of the whole reactants driven by stirring The speed is low, so that it cannot fully and efficiently react with the gas, resulting in reduced production efficiency and production quality
