Description

A kind of electrolyzer of capable of adjusting electrode spacing
Technical field
The utility model relates to a kind of electrolyzer that is applied to sewage disposal, and particularly a kind of electrolyzer of capable of adjusting electrode spacing belongs to the environmental improvement technical field.
Background technology
Along with increasing sharply of rapid development of economy and population, wastewater discharge increases day by day, and environmental pollution is day by day serious, and environment protection and conservation of resources have become subject matter and the key factor of Economic development.China is lack of water country, and the water that is on the rise pollutes that to be tantamount to be to make the matter worse, and quite a few that makes original limited water resources lost use value.Because the high-concentration waste water of the industry dischargings such as heavy metal, compound and organic waste water etc., especially chemistry in the sewage, food, agricultural chemicals, dyestuff and medicine, colourity is high, toxicity is large, contains large number of biological difficult degradation composition, uses traditional method to be difficult to process.
Electrochemical process is playing a significant role aspect the recovery of plant effuent and the processing, especially aspect the bio-compatibility of the toxic pollutant in reducing water or poisonous pollution.
So-called electrochemical process is to utilize the chemical reaction of electrolytic process, is the sewage water treatment method that the detrimental impurity in the industrial sewage is removed with reformulations.As far back as the forties in 20th century, domestic since the sixties abroad, just contain cyanogen in constantly research and Applied Electrochemistry method processing, contain phenol, the industrial sewage of the number of different types such as printing and dyeing, process hides.Electrochemical process is processed waste water and generally be need not a lot of pharmaceutical chemicalss, and aftertreatment is simple, and floor space is little, and convenient management, sludge quantity seldom are called as the clean method.
But utilize at present the sewage disposal device of electrochemical process also to have following shortcoming and defect:
1. the electrode inertia is bad, and electrochemical window is narrow, the circulation ratio of electrode and poor stability, and the steady state current time of response is long, so electrode life is short, and sewage treating efficiency and clearance are low.
2. the electrochemical oxidation index of electrode is on the low side, and electrode performance is bad because hard-degraded substance sometimes can not exhaustive oxidation, can only be oxidized to toxicity lower be convenient to biodegradable material, the intermediate product toxicity that sometimes produces is larger than former target product toxicity.
Shortcoming based on above-mentioned existence, in recent years, for different electrodes, designed dissimilar electrochemistry waste disposal plants, its key distinction is the structure of its electrolyzer, by the change to quality migration coefficient (pump electrolyzer and stirring rod electrolyzer) and electrode area (expansion electrolytic surface electrolyzer) and electrode materials (metal-doped diamond film electrode), inertia is bad to have obtained alleviation to a certain extent with the low shortcoming of oxidation capacity.
But because the interelectrode distance of electrolyzer is fixed, the discharge of passing through is fixed, and is certain to the processing speed of sewage.That is to say that when the current quantitative change of injecting electrolyzer was large, the throughput of current was lower in the unit time, efficient is not high; When the discharge of injecting electrolyzer diminished, wider interelectrode distance was so that the current density step-down, and electrolytic efficiency descends.Therefore, so that the adaptability of electrolyzer is often bad, be difficult to electrolytic efficiency is performed to ultimate attainment, reach energy-efficient purpose.
How to provide a kind of and can adjust distance between the electrode according to different discharge, become problem demanding prompt solution and reach better electrolysis effectiveness.
