Chemical reaction temperature control adjusting system and method

Abstract

The invention relates to a chemical reaction temperature control adjusting system and method. The system comprises a cold water pool, a hot water pool, a temperature adjusting pool, a reaction kettle and a control system, the outer layer of the reaction kettle is a temperature control medium layer; the control system comprises a first temperature sensor, input equipment, a second temperature sensor, a controller, a water pump, a liquid crystal display and a three-position four-way electromagnetic valve; the method comprises the following steps: 1, inputting the optimum reaction temperature of the reaction kettle to the controller through the input equipment; the first temperature sensor senses the temperature in the temperature control medium layer of the reaction kettle reaction; the second temperature sensor senses the temperature in the temperature adjusting pool; 2, the controller calculates a reaction error temperature; and thirdly, the controller controls the three-position four-way electromagnetic valve and all the water pumps. According to the invention, fine adjustment can be carried out; more energy and media are saved; automation is achieved, and manpower is saved.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a chemical reaction temperature control and regulation system and method. Background technique [0002] With the continuous improvement of people's living standards, people's dependence on chemical products is also increasing, such as plastic bags, gasoline and other chemical raw materials, and the preparation of these raw materials must be obtained through complex chemical reactions, so there must be a A chemical reaction device is used to add raw materials for reaction to produce corresponding products. [0003] The broad understanding of the reactor is that there is a physical or chemical reaction container. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. [0004] The optimum reaction temperature corresponding to different chemical react...

AI Technical Summary

Problems solved by technology

[0004] Different chemical reactions correspond to different optimum reaction temperatures, and the reaction temperature of a set of chemical reactions is also changing in real time. The outer layer of the existing reactor is equipped with a reaction temperature control medium layer, through which heat is transferred to the reaction medium layer. The reaction in the kettle; the temperature control medium layer of the reactor realizes temperature regulation by connecting hot water and cold water. Turn on the cold water at the same time, add cold water to the temperature control medium layer, the original water in the medium layer will be discharged directly, resulting in double waste of water and heat energy
