Abstract
The invention provides a chamber air float electrolysis device, relating to the technical field of electrolysis reactors, and comprising a gas-liquid mixing chamber and an electrolysis chamber. The gas-liquid mixing chamber comprises a gas-liquid mixing device and a gas-liquid separating device. The gas-liquid mixing device is an air float device or a gas-liquid mixer. An electrolysis electrode assembly is arranged in the electrolysis chamber. The electrolysis chamber and the gas-liquid separating device are placed in a same groove and separated by a clapboard. The electrolyzed liquid flows to the electrolysis chamber from the gas-liquid separating chamber through the clapboard. The application of the chamber air float electrolysis device in water treatment comprises the following steps of: (1) mixing waste water with oxygen or air; (2) separating waste water from gas; and (3) carrying out electrolytic oxidation. Because oxygen is dissolved in the electrolyte, no obvious bubbles exist among electrodes of the electrolytic cell, and resistance increase is avoided in the electrolytic cell, thereby the power consumption in process of electrolysis is reduced, the oxidation process of organic matters is accelerated, and the oxidation efficiency is improved at the same time.
Description
Technical field
The present invention relates to the electrolysis reactor technical field, specifically a kind of chamber air float electrolysis device and the application in wastewater treatment.
Background technology
Organic electrosynthesis is a cross discipline that relates to electrochemistry, organic synthesis and chemical engineering.Organic electrosynthesis is called as " ancient method, brand-new technology ".Organic electrochemistry is synthetic to be the frontier branch of science that organic electrosynthesis combines with electrochemical techniques, is widely used in synthesizing of fine chemicals such as dyestuff, medicine, agricultural chemicals, spices, organic reagent, amino acid and organic intermediate.Electrolytic oxidation is the important method of organic electrosynthesis, and this method has in handling waste water and need not to add oxygenant, and oxidation of organic compounds is thorough, non-secondary pollution, and equipment volume is little, and floor space is few, advantages such as convenient and flexible operation.The mechanism of electrolytic oxidation is divided into direct oxidation and indirect oxidation.Direct electrolytic oxidation is directly to utilize the anodic noble potential, by the organic or inorganic compound in the direct transfer transport oxidizing solution.Indirect oxidation mainly is the effect generation hydroxyl radical free radical isoreactivity group by electrode, and these active groups reoxidize the organism in the water body.
Chinese patent ZL00132781.X discloses a kind of catalytic electrolytic waste water treatment equipment, comprise direct supply, the reaction unit body, positive and negative electrode, water-in, rising pipe and catalyzer, it is characterized in that, the bottom of electrolyzer is " V " type, one inlet mouth is arranged in the bottom, perhaps inlet mouth and water-in are one, on inlet mouth top one flow deflector is arranged, flow deflector is convexly curved, crooked radian is the 0-90 degree, the flow deflector lower edge begins to extend from the inlet mouth top of reaction unit bottom, and a space is arranged between the lower edge of flow deflector and the cell body, and flow deflector begins to extend along the direction opposite with rising pipe one side from the inlet mouth top of reaction unit bottom, to the top of reaction unit.Catalyzer directed flow under this gas flow guiding effect, the utilization ratio of increase catalyzer reduces the energy consumption of reacting.Catalyzer has been adopted in this invention in electrolyzer, and organic effect in aerating oxygen or the air promote the oxidation waste water.But its shortcoming also is conspicuous.Use catalyzer must increase the cost of handling waste water.Owing in electrolyzer, directly feed gas, make to be full of a large amount of bubbles in the electrolytic solution, and will increase the resistance of electrolyzer, current consumption will improve.
How to quicken electrolytic oxidation, and to avoid improving current consumption be the problem to be solved in the present invention.
Summary of the invention
The purpose of this invention is to provide a kind of chamber air float electrolysis device and the application in wastewater treatment, quicken electrolytic oxidation and handle the waste water process, and avoid improving current consumption.
Realize the technical scheme of the object of the invention: a kind of chamber air float electrolysis device comprises gas-liquid mixed chamber and tank room.The gas-liquid mixed chamber comprises Liqiud-gas mixing device and gas-liquid separation device.Liqiud-gas mixing device adopts air-floating apparatus or gas liquid mixer.Gas liquid mixer is gas-liquid mixing pump, ejector, dynamic mixer or vortex gas-liquid mixing tank.Gas-liquid separation device is the container that opening is arranged at top.Be provided with the electrolysis electrode group in the tank room, entered by electrode group top, flow out from electrode group bottom by electrolyte.Tank room and gas-liquid separation device place same groove, and the middle dividing plate that adopts separates, and is gone into tank room by gas-liquid separation chamber via the dividing plate overflow by electrolyte.
Chamber air float electrolysis device of the present invention can be in wastewater treatment application, may further comprise the steps: (1) waste water and oxygen or air mixed; (2) waste water is separated from the gas; (3) electrolytic oxidation.
Because the present invention can make oxygen be dissolved in the electrolytic solution, does not have tangible bubble between electrolytic tank electrode, avoids increasing the resistance of electrolyzer, thereby can reduce the power consumption in the electrolytic process.Because the air supporting process has increased dissolved oxygen, in the free-radical oxidn process, can quicken organic oxidising process simultaneously, improve oxidation efficiency.
Purpose of the present invention, technical scheme and effect will be elaborated in conjunction with the embodiments.
