Description
Technical field
The present invention relates to a kind of ion-exchange membrane electrolyzer, particularly a kind of ion-exchange membrane electrolyzer with many gas-liquid channels.
Background technology
Gas-liquid channel in a bipolar type ion-exchange membrane electrolyzer of prior art is called the first gas-liquid channel, and refer to row's gas-liquid channel of gas-liquid separation chamber diapire next-door neighbour electrode network, this first gas-liquid channel is made up of the froth breaking net on top and the overflow plate of bottom.In anolyte compartment, this gas-liquid channel next-door neighbour anode network, chlorion floats by bubble buoyancy is vertical with the drive that electrolytic solution upwards flows after discharging on anode network and generating chlorine, top degree of inflation the closer to electrolyzer is larger, a part of gas-liquid that degree of inflation is very high flows to the first gas-liquid channel along anode network, finally enter gas-liquid separation chamber, wherein the chlorine of the vertical floating of a part and the light salt brine of generation can not be discharged from the first gas-liquid channel in time, be gathered in outside the diapire of gas-liquid separation chamber; The electrolytic solution that a fraction of chlorine is recycled in the process risen breaks up, float in the position away from anode network, more up degree of inflation is larger, this part gas floats with vertical but to be gathered in gas-liquid separation chamber's diapire together with the chlorine that the first gas-liquid channel is discharged also not in time, waits for from the first gas-liquid channel and discharging.
Along with people to ion-exchange membrane electrolyzer equipment enlarging, high efficiency require day by day strong, reduce the input of the support equipment such as utility line, instrument valve by improving separate unit production capacity thus reducing the construction costs and become the development trend of ion-exchange membrane electrolyzer, wherein improving the production capacity that current density improves separate unit electrolyzer is the method comparatively commonly used.Current density increases, and the chlorine that separate unit electrolyzer produces will be more, and the chlorine of generation increases, and the chlorine be gathered in outside ion-exchange membrane electrolyzer gas-liquid separation chamber diapire will get more and more.The chlorine assembled can not be discharged in time, not only affects the mass transfer of reactant and resultant, and the resistance making electrolytic reaction generate product increases, and this chlorine is gathered between anode and film, make bath voltage increase, the gas-liquid of gathering produces vibration together with tank room electrolyte inside, thus damage ionic membrane.The delay of chlorine outside electrolyzer diapire that this part can not be got rid of in time, also have impact on the circulation in anolyte compartment; The increase of tolerance also can increase the resistance of electrolytic solution, makes electric current distribution uneven; In addition, if large gas-liquid can not smooth and easyly derive, the sodium ion that the chlorine of gathering and negative electrode permeate hydroxide ion and the anode side of coming forms clorox, and then pile up and define salt bubble, film and salt steep and rubs, and can cause the breakage of film.
Fig. 1 is shown in by existing ion-exchange membrane electrolyzer gas-liquid separation chamber side-view, gas-liquid channel is platoon leader's square aperture of gas-liquid separation chamber diapire next-door neighbour electrode network, in anolyte compartment, when current density improves, the chlorine that part electrolysis generates and light salt brine can have little time to pass through from this gas-liquid channel, be gathered in outside the diapire between this gas-liquid channel at the bottom of anode disc, thus increase the pressure surge in tank room, make bath voltage increase.
Publication number is: disclose a kind of ion-exchange membrane electrolyzer in the patent of CN203295622U, gas-liquid channel in this electrolyzer gas-liquid separation chamber is arranged on the centre of gas-liquid separation chamber's diapire, when current density improves, amount of chlorine increases, part chlorine has little time from gas-liquid channel importing gas-liquid separation chamber gas-liquid separation chamber's diapire, the both sides of gas-liquid channel are piled up, a part is deposited in the angle of anode network and diapire, a part is deposited in the angle of trying to get to the heart of a matter with diapire, these chlorine assembled produce fluctuation, bath voltage is made to increase, and the chlorine piled up in the angle of anode network and diapire can impact ionic membrane, ionic membrane is very easily damaged.
In order to the light salt brine of the chlorine and generation that make more generations is discharged from gas-liquid channel smoothly, generally can select expansion first gas-liquid channel, namely the Kong Bian great of the first gas-liquid channel is made, although the change in this first gas-liquid channel hole to be assembled at gas-liquid separation chamber's diapire minimizing gas-liquid greatly certain effect outward.But the increase in this hole, the chlorine generated and light salt brine through its flow velocity when this hole can than before hole little time low through the flow velocity in this hole, the effect derived smoothly increase gas-liquid is made not to be very large, and this first gas-liquid channel hole is excessive, can make in gas-liquid separation chamber, connect the bad operation of upflow tube, actual processing is inconvenient.The hole increasing of this first gas-liquid channel can not make away from ionic membrane and the chlorine be gathered in equally outside gas-liquid separation chamber's diapire is derived very soon.The hole of this first gas-liquid channel is strengthened, and after unit groove also can be made to assemble in extrusion machine extrusion process, the ultimate compression strength step-down of its gas-liquid separation chamber, gas-liquid separation chamber is very easily crushed out of shape.
Summary of the invention
Based on above defect, the object of the present invention is to provide a kind of smooth and easy derivation of a large amount of gas-liquids that high current density can be made to produce, gas-liquid can be made again to reach many gas-liquid channels ion-exchange membrane electrolyzer of good separating effect.
Many gas-liquid channels ion-exchange membrane electrolyzer of the present invention is achieved through the following technical solutions:
