Description
Technical field
The utility model relates to a kind of electrolyzer that is used to purify water, and relates in particular to a kind of class of using and bores the electrolyzer of carbon material as electrode.
Background technology
Water is the main composition in the general organism, human especially survival indispensable nutrient, therefore be epochmaking natural resource in the world.With regard to tap water obtained in the daily life, its source comes from zones such as ocean, stream, lake water, rivers and creeks mostly, yet, in these areas, all have a large amount of organisms in water, also with follow as virus, bacterium (as colibacillus), pollen (as Radix Glycyrrhizae), unicellular organism (as ameba), algae (as green alga) simultaneously, dirt is walked haltingly or the harmful microorganism of louse or the like is stored in the water.And for industry zone in vogue, the waste water that factory's running is discharged more may cause severe contamination to water quality, make to contain for example organic pollutants such as greasy dirt, lacquer bits, sterilant, dioxin or plastics in the water; Or inorganic substance such as metal, mineral, in case it is through long-term drinking, may make human body that various pathologies take place.For this reason, purification of water quality is current important health subject under discussion.
Because microorganism and metal can be removed by oxidation and reduction reaction respectively, so can utilize electrode to switch in water usually, the generation by electric field purifies water.Electrode is traditionally made with metal, but because of metal may react with water, make water decomposition, and its activity also may be subjected to water quality impact and change, therefore propose a kind of with the electrolyzer of diamond as electrode, for example United States Patent (USP) the 6th, 328, No. 875, it has disclosed an electrochemical cell that is used for purifying water quality, is provided with an electrode group in an electrolyzer district, uses diamond as anode in this electrode group, with the contaminated water of purifying, also disclose similar techniques No. 2007/0272550 for another U.S. Patent Publication.Yet because diamond has high resistance, for improving its conductive characteristic, use boracic diamond has been proposed in addition as electrode, for example Japanese Patent is 2008-266158 number and 2005-176801 number, be disclosed in and be provided with an electrolysis cells in the container, this electrolysis cells is made up of anode, negative electrode and barrier film, wherein deposits a boracic diamond on the anode.Because if boron infiltrates diamond, it forms semi-conductor military order, so can promote its electrical conductivity.On using, because of the surface property of boracic diamond is a hydrophobicity, therefore the voltage that is applied when dissociating can strengthen, and that is to say that its ability for oxidation and reductive water is stronger, therefore will make the water quality after the purification more clean.In addition, United States Patent (USP) the 6th, 306, No. 270; And No. the 2010/126879th, U.S. Patent Publication, proposed too with the boracic diamond as electrolytic cell that electrode was constituted.
Because the boracic diamond must be with chemical Vapor deposition process (chemical vapordeposition, be called for short CVD) be plated on the base material, with this kind processing procedure, owing to be under about 800 to 900 ℃ high temperature, to carry out, generally easy catalysis diamond is made its greying down in this environment as metal or its alloy of platinum, iron, nickel, cobalt, so its interface tack is not good, diamond will break away from base material easily in use.Therefore, the boracic diamond must be plated on the base material that can form carbide usually, for example silicon or tungsten, also thereby limited the selectivity of its base material.In addition, because the production cost of boracic diamond is high, therefore be difficult to widespread usage on general brine electrolysis product.
The utility model content
