Embodiment 1

[0016] Anode using RuO 2 / C is used as a catalyst, and the cathode uses graphite powder as a catalyst. The process of preparing the cathode and anode electrodes is as follows: immerse the carbon paper in 10wt% PTFE emulsion for 1 to 2 minutes, take it out and dry it to remove the moisture therein. The amount of PTFE can be obtained by weighing the weight before and after impregnating PTFE, and the above process is repeated many times until the amount of PTFE impregnated into carbon paper meets the set requirements. Then put the above-mentioned hydrophobically treated carbon paper into a muffle furnace at 245° C. for half an hour to remove the surfactant in the PTFE emulsion. It was then treated at 345°C for another half an hour to melt the PTFE and form a hydrophobic network on the carbon paper fibers. PTFE content is 10wt.%. A microporous layer also needs to be prepared on the support layer to facilitate the loading of the catalyst. Weigh a certain amount of carbon powder...

Abstract

The invention relates to an electrochemical reactor for regeneration of chemical oxygen-iodine laser materials and a regeneration method. The reactor is formed by successively assembling a cathode plate, a cathode electrode, a cathode frame, a diaphragm, an anode frame, an anode electrode, an anode plate and the like, wherein the cathode frame and the anode frame are both formed by processing of acid and alkali resistant polymers. After assembled together, the cathode frame, the diaphragm and the cathode electrode are encircled to form a cathode compartment, and the anode frame, the diaphragm and the anode electrode are encircled to form an anode compartment. By the reactor, an aqueous solution of a chemical oxygen-iodine laser's product potassium chloride or sodium chloride and oxygen undergo an electrochemical reaction to be directly converted to chemical oxygen-iodine laser's required chemical raw materials chlorine and an alkaline hydrogen dioxide solution. Thus, regeneration of chemical oxygen-iodine laser materials is realized. The invention is suitable for field regeneration and reuse of chemical oxygen-iodine laser's chemical materials.

Description

technical field [0001] The invention relates to on-site regeneration and system integration technology of chemical raw materials for oxygen iodine chemical lasers, in particular to a reactor and regeneration method for raw materials regeneration of oxygen iodine chemical lasers. Background technique [0002] Oxygen iodine chemical laser is currently the only chemical laser successfully operating in electronic state transition. Oxygen iodine chemical laser is different from the first generation HF / HD chemical laser (wavelength 2.7-3.4μm), it has a shorter wavelength (1.315μm) , exactly in the atmospheric window. Oxygen-iodine chemical lasers have good application prospects in mechanical processing, materials, and medical technology. [0003] Yet oxygen-iodine chemical laser also has its weak points, and the main problems it faces are as follows: (1) its raw materials—alkaline hydrogen peroxide solution, chlorine gas, all have a certain degree of inconvenience in transportati...
