Reaction kettle with reflux ratio control and temperature and density interlock control

Abstract

The invention discloses a reaction kettle with reflux ratio control and temperature and density interlock control. The reaction kettle mainly comprises an outer frame, a cooling pipe, a stirrer, a pumping device, a shell and an electromagnetic valve, the stirrer is fixedly arranged in the middle of the top end of the outer frame in a penetrating way, a stirring rod is fixedly arranged at the bottom end of the stirrer and in the outer frame, a vacuum pipe penetrates through the left portion of the top end of the outer frame, a filter is fixedly installed at the bottom end of the vacuum pipe, and a vacuum pump is fixedly mounted at the left side of the filter. The reaction kettle is reasonable in structural design, capable of accurately controlling the reflux ratio, convenient and fast to use, high in practicability, capable of achieving temperature and density interlocking control, capable of enabling material separation to be more stable, capable of achieving uniform flow dividing andhedging cooling and good in condensation effect.

Description

technical field [0001] The invention relates to a reactor, in particular to a reactor with reflux ratio control and interlocking control of temperature and density. Background technique [0002] Distillation is a separation process that uses the different volatilities of the components in the mixture to separate the components. Commonly used equipment includes plate distillation towers and packed distillation towers. The principle and equipment process of precision distillation are the same as ordinary distillation, except that the relative volatility of the components in the system to be separated is small (<1.05~1.10), so high-efficiency precision packing is used to achieve the separation of the components to be separated Purification is a process in which the liquid mixture is heated to partially vaporize it, and then the steam is drawn out to condense into a condensate, so that the liquid mixture can be separated. [0003] The material separation in the existing reac...

AI Technical Summary

Problems solved by technology

[0003] The material separation in the existing reactor is insufficient, and the content of dinonylnaphthalene in monononylnaphthalene is high, resulting in low yield of dinonylnaphthalene products, slow cooling rate, and affecting the discharge efficiency
