Abstract

The invention relates to a strong oxidation reaction stirring reaction kettle which comprises a liquid sucking core type heat pipe type stirring shaft, heat radiation fins and heat absorption fins, wherein liquid sucking cores of liquid sucking core type heat pipes which extend into the reaction kettle from cooling tanks in a bent manner both comprise upper support rings, lower support rings and metal bars which are arranged inside heat pipe bodies; a plurality of metal bars are fixedly connected between the upper support rings and the lower support rings and are uniformly distributed in the circumferential directions of the upper support rings and the lower support rings; the metal bars are made of porous metal foams and the cross sections take the shape of inclined trapezoids; gaps between adjacent parallel metal bars and inclined trapezoid runners form channels of the liquid sucking cores together; the liquid sucking core type heat pipes which extend into the reaction kettle from the cooling tanks comprise vertical straight pipe sections and pulsation type bent pipe sections. The phenomenon of temperature runaway is effectively prevented.

Description

technical field [0001] The invention relates to a reactor, in particular to a stirred reactor for strong oxidation reaction. Background technique [0002] It is an important equipment commonly used in stirred reactor chemical production. Strong oxidation reaction is a typical strong exothermic reaction, and it is also a common type of reaction in chemical production, such as nitration reaction, strong oxidation reaction, and in the process of strong exothermic reaction In the process, if the heat of reaction cannot be transferred out in a timely manner, the temperature inside the reactor will rise rapidly in a short period of time, and reach a level that is difficult to control, resulting in the phenomenon of runaway temperature, which will lead to serious safety production accidents. An effective way to control the runaway temperature is to quickly and timely remove the heat generated in the reactor by using a suitable cooling method. [0003] The heat pipe is a new type o...
