Abstract
The utility model relates to a salt electrolytic cell and particularly relates to a zero pole electrolytic cell which is capable of reducing energy consumption. The zero pole electrolytic cell comprises an electrolytic cell, wherein the electrolytic comprises an ionic membrane (1), a cathode side structure and an anode net (3). The cathode side structure comprises a cathode net (2), the cathode net (2) is used as a skeleton, elastic components are arranged on the cathode net skeleton, and the elastic components are evenly distributed elastic supporting bodies (4) which are arranged on one side of the cathode net (2) opposite to the anode net (3). The elastic supporting bodies (4) are made of nickel materials. According to the structure, the cathode net attaches towards the anode net, the distance between electrodes is just the thickness of the ionic membrane, and the power consumption of corresponding tons of alkali is reduced by 150 kilowatt hours. The contact area between the nickel elastic bodies and the cathode nets is big, the pressure is even, and therefore, the cathode net, the ionic membrane and the anode net can be well compressed tightly together.
Description
Technical field
The utility model relates to a kind of salt electrolyzer, is specifically related to a kind of zero polar distance electrolytic bath.
Background technology
The highly energy-consuming of salt electrolysis technology, existing device is that NCH is a high electric density natural circulation multipole type electrolyzer.Electricity groove cathode and anode spacing affects the bath voltage size, and spacing is more little, and the unit groove bath voltage is low more, and it is just low more to produce power consumption accordingly.Exist the bigger distance of 1.8～2.2mm between the electric for a long time groove anode and cathode, this distance has the people to consider to break through from 3, therefore is exactly the electrolysis that realizes salt with highly energy-consuming for a long time.
Summary of the invention
The purpose of the utility model just provides a kind of zero polar distance electrolytic bath that cuts down the consumption of energy.Its technical scheme is: zero polar distance electrolytic bath comprises electrolyzer; Electrolyzer comprises ionic membrane, cathode side structure; The cathode side structure comprises cathode screen, anode network, and described cathode screen is provided with elastic component as skeleton on the cathode screen skeleton; The equally distributed elastic support of elastic component for being provided with in the relative side with anode network of cathode screen, elastic support is the nickel material.Adopt the zero polar distance electrolytic bath of said structure,, increase the elastic component of nickel material on this basis through doing skeleton with cathode screen; Make cathode screen be affixed to anode network, interelectrode distance is merely the thickness of ionic membrane, compared with prior art; Electrolyzer negative and positive interpolar spacing reduces 1.8～2.2mm; Voltage is reduced to 200mv, and zero polar distance electrolytic bath is than plain electrolysers bath voltage reduction 180mv down with uniform current density, and corresponding ton alkaline consumption electricity reduces 150kwh.Nickel matter elastomerics and cathode screen contact surface are big, and pressure is even, can cathode screen and ionic membrane, anode network well be pressed together.Calculate to produce 500000 tons of caustic soda abilities per year, but every year saves energy 7,500 ten thousand degree, reduce 72000 tons of CO2 emissions.This technical energy saving emission reduction effect is obvious, meets the requirement that present domestic chlor-alkali industry is produced.
