Problems solved by technology

The device uses flowing water to take away the temperature in the reactor to reduce the temperature in the reactor. However, when the temperature becomes very high, it takes a period of time for the flowing water to reduce the temperature in the reactor. In the high temperature reaction, although there is a pr

Abstract

The invention discloses an exothermic reaction device which comprises a reaction kettle and a condensing device, wherein a protective gas inlet is formed in the reaction kettle. The exothermic reaction device further comprises a PLC used for setting a control range of a temperature required by a process, wherein a liquid dropping and adding pipeline is arranged at the top of the reaction kettle, a flow regulating valve and a mass flow meter are connected onto the liquid dropping and adding pipeline, a temperature used for transmitting a signal to the PLC is arranged in the reaction kettle, and the flow regulating valve and the mass flow meter are controlled by the PLC to control the drop amount so as to control the heat yield in the reaction kettle. The exothermic reaction device has the characteristics that the reaction is stably and rapidly performed, and no side effect is caused.

Description

technical field [0001] The invention relates to a reaction device and an operation method, more specifically, it relates to an exothermic reaction device and a method for accurately determining temperature during the reaction process. Background technique [0002] A chemical reaction in which the total energy before the reaction is greater than the total energy after the reaction is called an exothermic reaction. [0003] The exothermic reaction device is for exothermic reaction of at least two raw materials to generate at least one product. At least two raw materials are mixed in the reactor. When the two raw materials are fully mixed, high temperature will be generated, and the reaction of the raw materials at high temperature is prone to reaction out of control or even side effects. [0004] The Chinese patent application number CN08204669.2 discloses a kind of exothermic reaction device, it comprises a tubular reactor, and this reactor has an inlet reactor head and an o...
