Reaction kettle with preheating device

Abstract

The invention relates to a reaction kettle with a preheating device. A reaction cavity and a storage cavity are arranged. Materials subjected to the initial reaction are introduced into the reaction cavity for reaction. After the reaction reaches a certain degree, gas generated by reaction of a material A and a material B is introduced into a ventilation preheating device through a gas outlet pipe, namely, the materials to be reacted can be preheated through the airflow of the primary reaction. Meanwhile, air flow subjected to heat exchange is introduced into an air bag to expand the air bag.When the reaction is carried out to a certain extent, namely the air bag expands to a certain extent, a switch can be touched to inflate a material storage box, so that materials in the material storage box are rushed out of a discharge pipe by airflow to enter the reaction cavity, the reaction degree in the reaction cavity is conveniently controlled, and the materials are automatically charged into the reaction cavity in which the reaction reaches a certain extent .

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a reactor with a preheating device. Background technique [0002] The reaction kettle generally has a preheating and heating process during the reaction. According to the heating method, it can be divided into electric heating, hot water heating, heat transfer oil circulation heating, far-infrared heating, external coil heating, etc.; its scope of application is suitable for petroleum, chemical industry , medicine, metallurgy, scientific research, colleges and universities and other departments conduct high temperature and high pressure chemical reaction experiments to complete hydrolysis, neutralization, crystallization, distillation, evaporation, storage, hydrogenation, polymerization, condensation, heating mixing, constant temperature reaction, etc. Process, the existing reactor reaction process has the situation of fractional reaction, that is, a variety of materials are add...

AI Technical Summary

Problems solved by technology

Through the cooperation of the negative pressure pipe and the feeding pipe, the material is sucked into it by the feeding tank in the negative pressure state; it can be seen that the feeding method in the prior art often requires a feeding device outside the valve body, and the timing and timing of feeding The quantity is not easy to control, and it is not possible to add materials in time during the reaction, nor can it preheat the added materials
