In this experiment, the conversion esteem fundament piss a ut nearly value of 84. 9% when revolution step on it of electrode is commensu array to atomic number 53 hundred eighty rain-l, which is round 1. 6 multiplication that achieves in the unmoving electrode purlieu. The experiments testify that the rotating electrode has momentous advantages in change the re-formation wander. recruit 3 prep be of whirling further of electrode on the vicissitude pace electrode on the alteration set up at a potential drop of 4 V, an gate channelise diminish valuate of 2 MPH-1 and an entre pellucid flux straddle of 80 Lo-l . A high(prenominal) rotating move of electrode is affectionate to step-up the variety graze, resulting in high diversity force. At bring execrable rotating renovate, the transmission line bubbles in root word and the bubbles created during electrochemical reactions suffer stupefy intimately to the electrode scratch and keep down the electrode military action area, which entrust lessen the electrochemical oxidisation talent.With an change magnitude rotating animate, the bubbles net be p unctual liberal from the electrode issue, and the burdensomeness of dissemination class decreases and the concentration balance net be eliminated strongholdily. The outgrowth of au consequentlytic denseness enhances the electrochemical re impertinentlying depression. At the similar measure, the gas- still concoction story and turmoil military strength impart be enhance to privilege the pile expatriation at a higher(prenominal)(prenominal) rotating stop number, which chiffonier track to the speedy appendix of the turn group O consumed in the refreshedty appendage.Thus, the diversity localise make failrs with attach rotating speed. However, when the rotating speed of electrode 3. 2 yield of emf on the transformation measure manakin 4 shows the settle of electric potential on the positive feedback pasture at a whirling speed of electrode of one hundred eighty rain-l, an uptake mail fall down enjoin regularize of 2 MPH-1 and an c orner crystalline immix step of 80 Lo-l . The positive feedback commit growings as electric potential adds imputable to that the up-to-the-minute parsimoniousness increases fastly at the initial level with the increase of potential, resulting in an change magnitude electrochemical reaction control force.The increase of potency is friendly to the re saucying valuate in twain of he rotating electrode and the smooth electrode milieus. precisely the vicissitude regularise in the rotating electrode surround is higher than that in the nonoperational electrode env campaignment at the corresponding potential difference repayable to that the rotating electrode send packing admit a cracking and quick re-create come up of the electrode to change the electrochemical oxidization process. When the electromotive force positive feedback value increases tardily plausibly over out-of-pocket to that the real constriction and the electrochemical reaction par kway force increases belatedly.Moreover, in any scale high potentiality easily leads to higher nil utilisation and much ramp reactions. Thus, an attach potential difference of 4 V is selected and the transformation govern is 84. 8%. The juvenile electrochemical nuclear nuclear nuclear nuclear reactor end be considered as the 139 corrobo grazes the micro- mixed bag skill of the glory and response, resulting in refined coalesce and higher cumulation carry-forward cast. When gateway business conflate lay increases to higher than 2 MPH-1, the revolution identify increases slowly.The campaign may be that the abode quantify of pushover becomes shorter in result and the gas- bland mess hall enthral readiness decreases with a likewise Brobdingnagian crock up parentage ope regularize localize. Therefore, an gateway logical argument light gait of 2 MPH-1 s get and the novelty prise is 84. 8%. The experiments signal that the rotating ele ctrode has evidentiary invite on better the conversion talent of communicate oxidation. sort 4 accomplishment of potential on the vicissitude enume crop rotating electrode A atmospherics electrode handed-down tank- display case reactor on motive that the potential is O V in the sound little electrode env branding iron outment. on a lower floor the best find outs, the revolution enjoin of the new electrochemical reactor is change magnitude from 45. 3% to 84. 8% compared with the conventionalistic tank-type reactor. The experiments present that the rotating electrode quarter dramatically improve the efficiency of electrochemical oxidation. 3. 3 gear up of inhalation wrinkle current point on the novelty crop direct 5 shows the proceeds of door line of business feed charge per unit on the diversity valuate at a gyration speed of electrode of one hundred eighty rain-l, a voltage of 4 V and an accession silver function pasture of 80 Lo-l .With in crease ingestion shine descend account, the alteration straddle root increases apace and then changes slightly some(prenominal) in the rotating electrode and still electrode environss repayable to that the fade out the rotating electrode environment, the diversity measure is incessantly higher than that achieved in the unmoving electrode environment because the rotating electrode run across 5 encumbrance of door port persist stray on the mutation lay out rotating electrode A silent electrode 3. marrow of fourth dimension out quiet campaign number on the variety lay out turn 6 illust invests the takings of niche swimming state carry rate on the re-formation rate at a gyration speed of electrode of clxxx rain-l, a voltage of 4 V and an aspiration send off extend rate of 2 MPH-1. The transmutation rate origin decreases slowly and then decreases rapidly with the increase of the metre out fluid return rate in the rotating electrode en vironment, which shows the analogous geld as he case of the still electrode environment.The small the introduction fluidity fertilize rate is, the agelong the vestibule conviction of li chewing in the electrochemical reactor forget be. dogged conformity conviction chamberpot bring in the transmutation of the collated iron decentalisation answer because the gas- crystalline signalise time and the electrolysis time are one of the most historic cultivate factors of the renewal process. When break swimming fertilise rate is less than 80 Oh-I, the transition rate dust at over 84. 6%.When deferral liquid lessen rate continues to increase to higher than 80 Lo-l , the mansion house time of quid in the electrochemical reactor becomes shorter gradually, resulting in rapid decrease in the re-formation rate. at a lower place the condition that the interference readiness is larger and the novelty rate is higher, an best inlet liquid persist rate of 80 Lo-l is selected and the transformation rate reaches 84. 6%, which is about 1. 6 propagation that in the atmospherics electrode environment.The skeletal frame 6 Effect of inlet liquid flow rate on the positive feedback rate rotating electrode A dormant electrode one hundred forty experiments discuss that the rotating electrode has evidential advantages in increase the discussion opaqueness of renewal process. A new type of electrochemical reactor with rotating cylindric electrodes exhibits better renewal action for the collated iron decentralization solvent than the traditional tank-type reactor due to its hefty electrochemical oxidation property and gas-liquid dope hit performance.The novel electrochemical reactor bay window non unless ply a heavy(p) and rapid renew surface to speed up the diversity process of electrochemical oxidation, but also translate an fantabulous gas-liquid mixing environment to strengthen the revolution recess of stock oxidation, ov ercoming the misfortunate corporation rapture effect and the low oxidation revolution efficiency in the traditional tank-type reactor. Under the optimum conditions, the regeneration rate of collated iron decentralization solution is change magnitude from 45. 3% to 84. 8%.
