Mesh sheets are freely expended, the utility model has the advantages of adjustable electrode, small resistance, good electrical conduction property, energy saving, consumption reduction and long service life, the cell voltage is reduced by 200-400 mv, and the power is saved by 150-250 kwh for electrolyzing a ton of alkalis.
Description
The utility model belongs to chemical industry equipment, particularly a kind of expanded anode electrolyzer that is used for the chemical industry chlor-alkali industry.
At the electrolyzer with metal anodes of chlor-alkali industry use, the metal anode of installing in cathode box is fixed anode strip, can not change the electrode pole span at present, it is bigger to consume energy, and the negative electrode mesh bag is two-sided sawtooth circular shape, makes the current circuit path propagation, increase conductive resistance, increase current consumption.Liquid-through hole on the round steel support when electric tank working, is often stopped up by fibrous magnesium silicate, and discharging hydrogen and circulation of elecrolyte are obstructed, and makes hydrogen content height in the chlorine, influences the quality product of chlorine industry.
The purpose of this utility model is to overcome above technical deficiency, and a kind of little power consumption, expanded anode electrolyzer that electrode life is big are provided.
The expanded anode electrolyzer is installed negative electrode mesh bag and expanded anode in cathode box, be side plate in negative electrode mesh bag both sides, and the above and below is the graticules sheet, warp-wise is straight iron wire, and broadwise is a sawtooth circular arc iron wire, mounting bracket in the net sheet, shorten current path, reduce resistance value.Run through the net sheet of above and below at the center pole rod of expanded anode, the expansion reed is a fulcrum with the center pole rod, more than, the anode network sheet is that the inflexion point symmetry is installed down, the anode network sheet is expanded freely, changed the electrode pole span, reduce bath resistance, the economize on electricity consumption reduction prolongs electrode life.
The pole span of expanded anode electrolyzer is adjustable, and resistance is little, can work under higher current density, and the cathode screen sheet is the graticules sheet, reduces resistance, energy-conservation, the electrolytic production steady quality.
