Compulsory internal recycle fluorination electrolysis reactor

Abstract

The invention discloses a fluorination electrolysis reactor, which comprises a reaction kettle with an inner chamber, a pair of negative electrode and positive electrode leading-out terminals, a plurality of negative and positive plates, a mixer, a rotating shaft and a motor. The positive plates and negative plates are all flat rectangles, and are alternately arranged at preset interval into electrode stacks; the mixer is connected to the motor through the rotating shaft; the electrode stacks are arranged around the mixer into a ring; and the gap between the electrode plates generally orient the mixer. Adjacent electrode stacks can be arranged in choking connection to prevent flow of the electrolyte along the gaps between the stacks. The simple equipment employs a compulsory internal recycle mode; electrolysis products are easily controlled and derived in an electrolytic reaction process, so as to facilitate enrichment discharge of the reaction products; and the reactor effectively increases product yield, expands the varieties of fluoride products from the electrolytic reaction and the usage scope of the electrolytic tank.

Description

technical field [0001] The invention relates to an electrolytic reactor for organic electrochemical synthesis, in particular to a reactor for fluorination electrolysis through internal forced circulation. Background technique [0002] In the organic fluorination electrolysis equipment in the prior art, the electrolytic electrodes are all anode plates and cathode plates in a rectangular shape with intervals for cross-insulation, vertically stacked and statically suspended in the electrolytic cell, and connected to the outside of the electrolytic cell by terminal posts. According to the connection mode of the electrodes, it can be generally divided into two types of electrolyzers: monopolar and bipolar. [0003] The electrodes of the same polarity in the unipolar electrolytic cell are connected in parallel with the DC power supply, and the polarity of both sides of the electrodes is the same, that is, both are anodes or cathodes at the same time. The electrodes at both ends o...
