The middle partition boards 2-8 are in frame-shaped structures.
Preferably, support brackets 2-9 are provided at the bottom of the intermediate partitions 2-8. It is further preferred that a plurality of supporting partitions 2-14 are respectively provided at the left partition unit 2-6 and the right partition unit. The thickness of the intermediate partition 2-8 is usually 60-150 mm.
As shown in fig. 2-1, the middle partition plates 2-8 are disposed between the left-end partition plate and the right-end partition plate, so that the plurality of partition plate units disposed in an overlapping manner are divided into a left partition plate unit 2-6 disposed in an overlapping manner between the left-end partition plate 2-4 and the middle partition plate 2-8, and a right partition plate unit 2-7 disposed in an overlapping manner between the right-end partition plate 2-5 and the middle partition plate 2-8.

Due to the large-scale of the electrolytic tank, the tank body is very long, taking the electrolytic tank with the specification of 1000m < 3 >/h as an example, the length of the tank body reaches about 6m, and the weight is more than 60 tons. In order to prevent the middle of the electrolytic cell from sinking, the supporting brackets 2-9 are particularly added at the bottom of the middle partition boards 2-8, and the supporting partition boards 2-14 are arranged for the electrolytic cell with larger size, so that the problem that the middle of the electrolytic cell sags after running for some time is solved. And insulating plates are used for electrical isolation among the supporting partition plate, the supporting bracket and the foundation.

As shown in fig. 3 and 4, each partition plate unit comprises a partition plate frame 3-1, and a partition plate core 3-2 is welded in the partition plate frame 3-1. The baffle core comprises a single-sided corrugated plate structure, as shown in FIGS. 7-1, 7-2, 8-1 and 8-2; or as shown in fig. 9-1 and 9-2, the baffle core 3-2 comprises a flat plate 9-3, and a left corrugated plate structure 9-1 and a right corrugated plate structure 9-2 are respectively fixed on the left side wall and the right side wall of the flat plate. The contact positions of the left corrugated plate structure 9-1 and the right corrugated plate structure 9-2 and the flat plate 9-3 are preferably fixed by welding. The corrugated plate structure can be formed by adopting mechanical processing methods such as die stamping, rolling and the like.

Preferably, the thickness of the single-sided corrugated plate structure, the flat plate 9-3, the left-sided corrugated plate structure 9-1 and the right-sided corrugated plate structure 9-2 is 0.3-2 mm.
As the first embodiment shown in fig. 7-1 and 7-2 and the second embodiment shown in fig. 8-1 and 8-2 of the present invention, when the single-sided corrugated plate structure is adopted, the adjacent crest distance W1 of the corrugations of the single-sided corrugated plate structure of the first embodiment and the adjacent crest distance W2 of the corrugations of the single-sided corrugated plate structure of the second embodiment are both 8 to 30mm; the peak-to-valley height difference H1 of the corrugations of the single-sided corrugated plate structure of the first embodiment and the peak-to-valley height difference H2 of the corrugations of the single-sided corrugated plate structure of the second embodiment are both 8-30 mm; wherein the orthographic projection of the wave crest of the single-sided corrugated plate structure on the vertical plane is a continuous broken line shape, and the parameters of the single-sided corrugated plate structure are set as follows: the inclination angle alpha 1 formed by the wave crest and the vertical longitudinal axis of the flat plate is more than 0 and less than or equal to 45 degrees, the inner angle alpha 2 of the wave crest or the wave trough formed along the vertical longitudinal axis direction of the flat plate is more than 90 degrees, and the inner angle alpha 3 of the wave crest or the wave trough formed along the thickness direction of the flat plate is 45-135 degrees; preferably, in the cross section direction of the partition board core, the corrugations of the single-face corrugated board structures on the two partition board cores which are arranged in a left-right overlapping mode are mutually reversely inclined, so that the wave crests of the two single-face corrugated board structures are opposite to each other and cross to form a three-dimensional net structure. This makes it possible to firmly clamp the membrane electrode assembly between the two separator cores at each intersection point in the three-dimensional network structure, and to stabilize the position. When the wave crests of the single-sided corrugated plate structure adopt the orthographic projection on the vertical plane to be in a continuous linear shape, the internal angle alpha 4 of the wave crests or the wave troughs formed along the thickness direction of the flat plate is 45-135 degrees.
As a third embodiment of the present invention, as shown in fig. 9-1 and 9-2, when a left corrugated plate structure 9-1 and a right corrugated plate structure 9-2 are respectively fixed on the left and right side walls of the flat plate, an included angle between a peak of the left corrugated plate structure 9-1 and the right corrugated plate structure 9-2 and a vertical longitudinal axis of the flat plate is 0 < α 5 ≦ 45 °; an inner angle alpha 6 of a peak or a valley formed along the thickness direction of the flat plate is 45-135 degrees; the distance W3 between adjacent wave crests of the corrugations is 8-20 mm; the height difference H3 between the peaks and the valleys of the corrugations is 3-15 mm.
The single-sided corrugated plate structure, the flat plate 9-3, the left-sided corrugated plate structure 9-1 and the right-sided corrugated plate structure 9-2 can adopt carbon steel nickel-plated plates and nickel plates, when carbon steel nickel-plated materials are adopted, the thickness of a plated layer is 40-120 mu m, and a nickel metal layer is used for preventing corrosion. The left corrugated plate structure 9-1 and the right corrugated plate structure 9-2 can also adopt metal nets to be pressed into corrugated structures, the metal nets are 4-30 meshes, and the wire diameters of the woven metal nets are 1-0.2 mm.
In the above three embodiments, the smaller the inclination angle of the fold line ripple is, the more favorable the uniform distribution of the electrolyte is, and the flow resistance of the electrolyte is small; the distance between wave peaks is small, the support is firm, and the flow resistance of the electrolyte is large; and if the distance is large, the opposite is true. The peak-valley height difference is small, the resistance of the electrolyte is reduced, the flow rate of the electrolyte is large, the gas content is reduced, the electrolysis efficiency is high, and if the flow rate is too small, the gas content is increased; if the height difference is large, the opposite is true, but the gas content is small.
The single-sided corrugated plate structure in the first structure and the second structure greatly reduces the manufacturing cost compared with the clapboard core in the double-sided corrugated plate structure in the third structure, saves materials and saves processing cost. The second configuration shown in FIGS. 8-1 and 8-2 has the following disadvantages: the wave crests of the corrugated plate structures on the two partition plate cores which are arranged in a left-right overlapping mode are arranged oppositely to form a supporting structure, so that the machining errors of the two corrugated plates are small, the positioning accuracy is high, and the manufacturing difficulty is increased.
