Abstract
The utility model relates to a high current density film polar distance electrolytic cell. The high current density film polar distance electrolytic cell comprises a cathode side and an anode side, and is characterized in that an elastic screen (2) is added outside a cathode screen (1) of the cathode side, a noble metal coating is coated on a nickel wire mesh grid (3) of the cathode side, the anode side comprises a liquid inlet distribution pipe (4) at the bottom, a plurality of rib plates (5) which are vertically arranged at the middle part and a gas-liquid separation box (6) at the top, two flow deflectors (8) are arranged between two adjacent rib plates (5), and a defoamer (9) is arranged in the gas-liquid separation box (6). According to the high current density film polar distance electrolytic cell disclosed by the utility model, as the cathode side and the anode side of the existing electrolytic cell are reformed, a low current density electrolytic cell is refitted into the high current density film polar distance electrolytic cell, and the refitted high current density film polar distance electrolytic cell has the advantages that the cell voltage is low, and the cost is lowered while the power consumption is low.
Description
Technical field
The utility model relates to a kind of high electric density membrane polar distance electrolytic bath.
Background technology
Along with the develop rapidly of Chinese chlorine industry, China has formed nearly 4,000 ten thousand t/a caustic soda production capacities at present.Wherein, it is nearly 90% that ionic membrane method accounts for, and average power consumption index is 2350kwh/t, and diaphragm process accounts for 10%, and average power consumption index is 2700 kwh/t.World's chlor-alkali technological development direction is novel energy-saving and cost-reducing technology.Nearest 2 ~ 3 years, it is nearly 2/3 that diaphragm sell has been eliminated, and the newly-increased high electric density of natural circulation before this electrolyzer is natural circulation high electric density membrane polar distance electrolytic bath then.Along with the development in city, chlor-alkali industry is all constantly being moved outside and is being expanded production, newly go up support equipment such as rectification and press the high electric density system configuration, the low electric close cell performance of original natural circulation still can, device is worth also very high, the very waste of giving it up.Therefore seek a kind of reducing cost, particularly important by the high electric density membrane polar distance electrolytic bath that low electric close electrolyzer is reequiped.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and reduces cost, by hanging down the high electric density membrane polar distance electrolytic bath that electric close electrolyzer is reequiped.
The purpose of this utility model is achieved in that
A kind of high electric density membrane polar distance electrolytic bath, it comprises cathode side and anode side, the cathode screen of described cathode side adds the dress elastic network(s), be coated with noble coatings in the nickel wire mesh grid of described cathode side, described anode side comprises the vertical a plurality of gussets arranged in feed liquor distribution piping, middle part of bottom and the gas-liquid separation box at top, be provided with two flow deflectors between described adjacent two gussets, be provided with froth breaker in the described gas-liquid separation box.
As a kind of preferred, the inner vertical layout of following flow deflector is arranged in the top oblique outer top of flow deflector in two flow deflectors.
Compared with prior art, the beneficial effects of the utility model are:
The utility model makes low electric close electrolyzer repack the high electric density membrane polar distance electrolytic bath into because cathode side and the anode side of former electrolyzer are transformed, and the high electric density membrane polar distance electrolytic bath after the repacking has that groove forces down and power consumption has reduced cost low the time.

Embodiment
Referring to Fig. 1 ~ Fig. 5, a kind of high electric density membrane polar distance electrolytic bath that the utility model relates to, it comprises cathode side and anode side, the cathode screen 1 of described cathode side adds dress elastic network(s) 2, be coated with noble coatings in the nickel wire mesh grid 3 of described cathode side, make the oxide compound of precious metal become the oxide junction crystal by thermal oxidation method, described anode side comprises the feed liquor distribution piping 4 of bottom, the vertical a plurality of gussets 5 arranged in middle part and the gas-liquid separation box 6 at top, described feed liquor distribution piping 4 has replaced traditional feed liquor distributor disk 7, be provided with two flow deflectors 8 between described adjacent two gussets 5, top flow deflector 8 oblique outer tops are arranged, following flow deflector 8 inner vertical layouts are provided with froth breaker 9 in the described gas-liquid separation box 6.
Anode side adopts feed liquor distribution piping 4 to replace traditional feed liquor distributor disk 7, make the interior strength of solution of feed liquor pit distribute more even, the chlorine of output is discharged into house steward smoothly behind froth breaker 9 froth breakings, can not form and breathe heavily flow phenomenon and influence groove and press stablely, improved high electric density membrane polar distance electrolytic bath has the advantages that groove forces down and power consumption is low.
