Abstract
The utility model relates to an electrolysis bath for electrolyzing hydrofluoric acid. A cathode device of the electrolysis bath comprises a cathode plate and cathode rods, wherein the cathode rods are connected with the left end and the right end of the cathode plate; the cathode rods are symmetrically distributed on the left end and the right end of the cathode plate about a perpendicular center line of the cathode plate as a symmetry axis; and the cathode rods are connected in parallel with a power source. Through the balance of the quantity of the cathode rods on the left end and the right end of the cathode plate and the size of the resistance, the cathode device of the electrolysis bath enables the current passing through each cathode rod and the generated heat to be the same, and the current distribution on the cathode plate is relatively balanced as well; when the cathode device is applied in the electrolysis bath, the defects (for example, equipment is easy to damage, the electrolytic current is far lower than the rated current, the electrolytic efficiency is low, the electrolytic reaction is uneven and the like) caused by bias current can be overcome; under the premise of guaranteeing the equipment not to be damaged, the electrolytic current can be improved to the rated current, and the due capability of the electrolysis bath is fully exerted, which causes the electrolytic efficiency of the electrolysis bath to be promoted greatly, and is simultaneously beneficial to the reduction of power waste.

Background technology
The cathode assembly of existing electrolyzer for the electrolysis hydrogen fluoric acid, as depicted in figs. 1 and 2, comprise negative plate 1 and the cathode rod 2 that is connected to two ends, negative plate 1 left and right sides, wherein, the cathode rod 2 on the left side is one, the cathode rod 2 on the right is in parallel two, and the cathode rod 2 on both sides together accesses power supply provides electrolysis required electric energy for negative plate 1.There is following defective in this cathode assembly:
Calculation formula according to resistance: R=ρ L/S(R is resistance, ρ is resistivity, L is length, S is sectional area) as can be known, the resistance of the cathode rod 2 on the left side is the twice of resistance of the cathode rod 2 on the right, when therefore passing into electric current, is electric current according to the calculation formula of electric current: I=U/R(I, U is voltage, and R is resistance) and Joule's law Q=I
2Rt(Q is heat, t is the time) as can be known, the cathode rod 2 access power supplys in parallel of the right and left, therefore in the situation that voltage is identical, the electric current that the electric current that passes through of cathode rod 2 on the right and the heat of generation all pass through greater than the cathode rod 2 on the left side and the heat of generation, if be the high electric current that 4000A passes into 4000A according to the rated current of electrolyzer in when design, then cause easily the right each node on the cathode rod 2 to be connected the part that cathode rod 2 is connected with power supply with conductive bus bar) be burned, and because the electric current on both sides is inconsistent, cause the electrolytic reaction at two ends, the left and right sides of negative plate 1 inhomogeneous, electrolytic efficiency is lowered.For each node and the conductive bus bar that prevents cathode rod 2 is burned, have to reduce reaction current in the actual production to 2500A, can not give full play to the ability of electrolyzer, reduced the efficient of electrolytic reaction.
