Abstract

The constant temperature control system for hydrogenation reaction of 1,4-butene diol relates to the technical field of constant temperature system. The tube cooler is set in the reaction kettle, and the automatic control device includes a central processing module, a regulating valve and a temperature transmitter for detecting the temperature of the solution in the reaction kettle. The regulating valve and the temperature transmitter are respectively connected to the lines of the central processing module. The regulating valve is connected to the water inlet end of the coil cooler, and the temperature transmitter is connected to the reaction kettle. Compared with the prior art, the constant temperature control system of the present invention can not only sense the change of the reaction temperature of the solution in time, but also quickly adjust the flow rate of the cooling water to ensure that the solution can efficiently generate 1,4-butenediol within the temperature difference range of ±2°C , and the operation is simple and the cost is low.

Description

technical field [0001] The invention relates to the field of constant temperature systems, in particular to a constant temperature control system for hydrogenation reaction of 1,4-butenediol. Background technique [0002] 1,4-butenediol is produced by the reaction of 1,4-butynediol and hydrogen. The reaction process will release a large amount of heat, which will gradually increase the temperature of the solution. If the reaction temperature is too high, it will easily affect the progress of the reaction. To ensure The quality of the product and the safety of the reaction must ensure that the reaction temperature of the solution is relatively stable. Therefore, effective cooling control is required in the production process of 1,4-butenediol. [0003] The conventional cooling method for the hydrogenation reaction of 1,4-butenediol has a manual or PID regulator to control the flow of cooling water, but the exothermic process of the hydrogenation reaction is related to multipl...
