Abstract
The invention belongs to the technical field of electrochemical electrolysis, and particularly relates to a following cathode device with the distance between the following cathode device and an active anode kept unchanged and application of the following cathode device. The cathode device comprises four special-shaped flat plates. The special-shaped flat plates are arranged according to the four edges of the external square of the active anode. When the active anode is shrunk, the special-shaped flat plates move along the diagonal lines of the square towards center of the square. The moving speeds of the four special-shaped flat plates are the same and are square root of 2 times of the shrinkage speed of the active anode. The following cathode device can be used as a cathode when high-temperature reactor fuel element matrix graphite is disassembled through an electrochemical intercalation method. The following cathode device is simple in structure, the effective area of a cathode pole plate is large, the distance between the cathode and the anode is kept unchanged in the whole electrolysis process, and resistance in the electrolysis process is effectively reduced.
Description
Technical field
The invention belongs to electrochemical electrolysis technical field, and in particular to a kind of to keep constant following with active anode spacing
Cathode assembly and application.
Background technology
The post processing of high temperature gas cooled reactor spent fuel is extremely important, it is necessary to the spy of the spheric fuel element structure that pin is used for
Different property, carries out special disintegration research.In various disassembling methods, electrochemical intercalation method mild condition does not discharge radioactive nucleus
Element, is more suitable method.
In electrochemical intercalation method, spheric fuel element constantly reduces as active anode, if negative electrode is consolidated using conventional
Determine motionless form, then negative and positive die opening will constantly increase, and cause the Joule heat of electrolytic process constantly to increase, and not only reduce
The energy efficiency of electric current, also increases the cooling burden of system.
The method for reducing electrolytic process resistance is the space arrangement for optimizing electrode；And negative electrode is moved, with activity
The diminution of anode and follow close.However, each minus plate can mutually stop when mobile, make interleaved between each minus plate
The conventional method of groove can cause the loss of minus plate effective area again.
The content of the invention
Keep constant with active anode spacing and follow cathode assembly the invention provides a kind of, concrete technical scheme is such as
Under：
A kind of the follow cathode assembly, the cathode assembly constant with the holding of active anode spacing include 4 special-shaped flat boards；
The special-shaped flat board presses the external foursquare four side arrangement of active anode；When active anode reduces, along foursquare right
Linea angulata is moved to foursquare center.
The described 4 translational speed all sames of special-shaped flat board, are that active anode reduces speedTimes.
When following cathode assembly to can be used as electrochemical intercalation method disintegration high temperature nuclear reactor fuel element matrix graphite as described above
Negative electrode.
Specific steps include：
(1) handle of 4 special-shaped flat boards for following cathode assembly is clamped with the mechanical device of electrolytic cell, 4 different
Type flat board presses the external foursquare four side arrangement of fuel element active anode, realizes mechanical erection；
(2) wire of connection electrolyzer power source negative pole screw-nut form through leading on 4 handles of special-shaped flat board
Hole simultaneously clamps, and realizes electrical connection；
(3) when being electrolysed, the mechanical device of electrolytic cell drives 4 special-shaped flat boards along foursquare diagonal to foursquare
Center is moved, and the size of translational speed is active anode diminution speedTimes.
The present invention has advantages below：1. can be used for the electrolytic process with spheric active anode, effectively reduce electricity
Resistance in solution preocess；2. minus plate effective area is not lost；3. simple structure, it is easy to install；4. the device is stainless steel
Make, it is with low cost, it is corrosion-resistant.
