A novel graphene ternary composite direct current-carrying plate
The invention relates to a direct current-carrying plate, in particular to a
novel graphene
ternary composite direct current-carrying plate and application thereof.
Sodium chlorate electrolysis is produced by electrolyzing industrial brine and
is the
main industrial production method. The method consumes a large amount of
electricity, and
consumes about 5,500 kW and h/t in the electrolysis process, and the power
consumption
accounts for about 60% of the product cost.
The electricity consumption for the production of sodium chlorate depends on
the level
of the electrolyzer, the choice of cell type and the advancement of
electrolysis technology.
The current-carrying plate is an important part of the electrolysis cell. The
traditional bus-bar
connection electrolysis technology uses bolts or bus bars to connect the
copper bars and
aluminum rows. The current loss of this technology is large, and there is a
short circuit of the
electrolytic cells, which seriously affects the normal operation of the
equipment. Nowadays,
the direct current-carrying technology of the baffle is used. This technique
requires good
conductivity and mechanical strength of the baffle. The baffle needs to have a
certain porosity
and lower ohmic voltage drop.
In view of the above deficiencies of the prior art, the present invention
provides a novel
graphene ternary composite direct current-carrying plate and the use thereof,
the carrier plate
has a small thickness, a reduced ohmic voltage, a good porosity, and a small
current loss.
The above object of the present invention is achieved by the following
technical
solutions:
