Description
Technical field
The utility model relates to a kind of electrolyzer, relates in particular to a kind of multipole type membrane polar distance electrolytic bath with circulation tube, belongs to chlorine industry technical field.
Background technology
The development of ion-exchange membrane electrolyzer is safe, clean, energy-conservation, stable to pursue, longevity is as target, and the electrolyzer using is now mainly multipole type natural circulation high electric density Small pole distance electrolytic cell and membrane polar distance electrolytic bath.There are more following problems in different electrolyzers:
1, unit electrolytic bath does not have gas-liquid separation chamber, and liquids and gases flow out under the state of gas-liquid mixed from drain pipe, causes in unit electrolytic bath and produces vibration, exists destruction ionic membrane and negative electrode trim to occur the shortcomings such as corrosion.Some unit electrolytic bath has gas-liquid separation chamber, but the porous froth breaking net of eliminating chlorine bubbles is not set in anode separate chamber, and more sticky because of chlorine, air pocket can cause the turbulent flow phenomenon of fluid equally, causes unit electrolytic bath internal vibration, has the hidden danger of destroying ionic membrane.And gas-liquid separation box is arranged on unit electrolytic bath top, the box basifacial of gas-liquid separation box, as trim, need bear seal request squeeze, and the box face of gas-liquid separation box exists the phenomenon that rigidity is inadequate, easily causes the leakage of trim.
2, the needs because installing, the size of ionic membrane must be greater than the physical dimension of unit electrolytic bath surrounding frame, and the utilization ratio of ionic membrane is not high, and production cost is higher.
3, the indoor circulation weir plate of conventional anode is to arrange in order to increase the electrolytic solution internal recycle between two gussets in anolyte compartment, in inner cyclic process owing to there being a certain amount of gas in electrolytic solution, the internal recycle that causes electrolytic solution is the circulation that gas-liquid coexists, the circulation of elecrolyte of circulation is insufficient, density unevenness is even, causes amount of electrolyte poor.
Therefore the multipole type membrane polar distance electrolytic bath of seeking a kind of high quality, high security, low cost, high life is particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and the multipole type membrane polar distance electrolytic bath of a kind of high quality, high security, low cost, high life is provided.
The purpose of this utility model is achieved in that
A kind of multipole type membrane polar distance electrolytic bath, it comprises the half-cell electrolyzer at multiple unit electrolytic baths and two ends, between described multiple unit electrolytic bath and between unit electrolytic bath and half-cell electrolyzer, be provided with ionic membrane and gasket seal, described unit electrolytic bath comprises anolyte compartment and cathode compartment, top in described anolyte compartment is provided with anode gas-liquid separation box, top in described cathode compartment is provided with negative electrode gas-liquid separation box, in described anode gas-liquid separation box, be provided with froth breaking net, in described anolyte compartment, between adjacent two gussets, be provided with circulation tube, the upper end of described circulation tube is connected with the bottom of anode gas-liquid separation box, the lower end of described circulation tube extends to the bottom of anolyte compartment.
Compared with prior art, the beneficial effects of the utility model are:
1, bear four frames that the trim of seal request squeeze is rigidity, make unit electrolytic bath be difficult for extrusion, guarantee sealing effectiveness, be not easy to cause the leakage of trim, safety performance is higher, and ionic membrane is saved more than 7 ~ 10%.
2, anode gas-liquid separation box and negative electrode gas-liquid separation box are arranged at anolyte compartment and cathode compartment inside, and anode gas-liquid separation box has built-in froth breaking net, have improved electric groove traveling comfort.
3, adopt the design of circulation tube, make electrolytic solution first separate and carry out internal recycle later again through anode gas-liquid separation box, making the internal recycle of electrolytic solution is liquid circulation separately, and the circulation of elecrolyte of circulation is abundant, and concentration is even, and amount of electrolyte is higher.
Therefore this multipole type membrane polar distance electrolytic bath has advantages of high quality, high security, low cost, high life.
