Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, fig. 1 is a partially enlarged schematic view of an electrode supporting structure provided in the present invention disposed on two sides of a plate.
The embodiment of the invention provides an electrode supporting structure, which is used for supporting a polar plate 2 and a secondary polar net of an electrolytic cell and comprises a supporting net 1, wherein the polar plate 2 and the secondary polar net are both of plate-shaped structures, and the supporting net 1 is supported between the polar plate 2 and the secondary polar net; the support net 1 is corrugated, a plurality of protruding ends 11 are uniformly arranged on two sides of the support net 1, each protruding end 11 can be tightly pressed or fixedly connected with the pole plate 2 or the auxiliary pole net at a corresponding position, the protruding ends 11 are corrugated wave crest positions or wave trough positions, and the protruding ends 11 of the adjacent support nets 1 are oppositely arranged to support the pole plate 2 and the auxiliary pole net.
By adopting the structure, the whole pole plate structure is split into the two supporting nets 1 and the plate-shaped pole plate 2, the structure of the supporting net 1 is simpler, the cost in the stamping manufacture process is lower, and the whole cost of the pole plate structure is greatly reduced.
Each protruding end 11 of the support net 1 may be abutted to and pressed against the corresponding pole plate 2 or sub-pole net, or may be fixedly connected with the corresponding pole plate 2 or sub-pole net by welding or the like, which is not limited in the present invention as long as the support net 1 can support the adjacent pole plate 2 and sub-pole net.
As shown in fig. 1, the protruding ends 11 are alternately arranged on two sides of the supporting nets 1, each protruding end of two adjacent supporting nets 1 is arranged oppositely to support the adjacent pole plate 2 and the sub-pole net, each protruding end 11 is gentle, the contact area with the pole plate 2 or the sub-pole net at the corresponding position is large, the protruding ends 11 which are required to be arranged oppositely to two adjacent supporting nets 1 can allow larger manufacturing error, further reduce the manufacturing requirement, and indirectly reduce the manufacturing cost.
After the support net 1 is provided with the protruding end 11, an electrolyte flow channel between the polar plate 2 and the auxiliary polar net is gentle, the flow channel resistance of the electrolyte in the flowing process is reduced, and the problem of large flowing resistance of the electrolyte is effectively solved; compared with the pole plate mechanism in the prior art, the protruding end 11 has the advantages that the width of the small electrolytic cell formed between the protruding end and the pole plate 2 and the auxiliary pole net is narrower, and the space required by electrolysis is smaller, so that the hydrogen yield of unit volume in the electrolytic cell is improved, the operation efficiency of the electrolytic cell is increased, and after the small electrolytic cell is reduced, the whole length of the electrolytic cell is reduced, so that the volume of the electrolytic cell is reduced, the supporting of the supporting structure to the electrolytic cell is facilitated, and the space utilization rate of the electrolytic cell is higher.
In this embodiment, the supporting net 1 is made of metal. In particular, the support net 1 can be made of pure iron or pure nickel, and the material has higher conductivity, so that the electrolysis efficiency of the electrolytic cell can be increased. In addition, the protruding ends 11 have certain elasticity, so that the positions of the protruding ends 11 can be adjusted in a small range while the polar plates 2 and the auxiliary polar net can be supported, manufacturing errors are further adapted, and the error requirement upper limit accepted during assembly is improved.
In the embodiment, the distance between the protruding end 11 arranged on one side of the supporting net 1 and the protruding end 11 arranged on the other side of the supporting net 1 in the whole thickness direction of the supporting net 1 is between 1 mm and 10 mm, i.e. T in fig. 1; the thickness of each position of the supporting net 1 is between 0.5 mm and 4 mm, namely S in figure 1; the distance between two adjacent protruding ends 11 arranged on the same side of the support net 1 in the length direction of the whole support net 1 is 3 mm to 25 mm, i.e. W in fig. 1.
The overall thickness direction of the support net 1 is the left-right direction in fig. 1, and the overall length direction of the support net 1 is the up-down direction in fig. 1. When the size of the support net 1 is within the above range, the support effect on the electrode plate 2 and the auxiliary electrode net and the electrolysis effect on the electrolytic cell are good.
The invention also provides an electrolytic cell which comprises an electrode supporting structure, a plurality of polar plates 2 and a plurality of auxiliary polar nets, wherein the electrode supporting structure is arranged between the adjacent polar plates 2 and the auxiliary polar nets. The electrode supporting structure is the electrode supporting structure described above, and since the electrode supporting structure has the above technical effects, the electrolytic cell including the electrode supporting structure should also have the same technical effects, and thus the details are not described herein again.
In this embodiment, the supporting net 1 and the pole plate 2 are made of metal and are fixedly connected by welding. This can make the support of the support net 1 more stable, and of course, as mentioned above, other connection methods can be used between the support net 1 and the pole plate 2.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
