Problems solved by technology

[0006] Although these two methods can delay corrosion to varying degrees, they cannot prevent the occurrence of corrosion, especially when the temperature control is not good or the nickel plating is defective, electrochemical corrosion will also occur very quickly.

Embodiment Construction

[0015] As shown in Figure 1, the anode connector is composed of an anode terminal 1, insulating mats 2, 3, 4, an anode seat 5, a compression nut 6 and a cathode terminal 7, and the anode terminal 1 can be made of the same material as the container 19 , also can adopt metals such as stainless steel, titanium, nickel to make, anode seat 5 and cathode terminal post 7 can adopt the same material making with container 19 or stainless steel making. The anode terminal 1 is tightly fixed in the anode holder through the compression nut 6 and the insulating pad 2, 3, 4, which acts as a seal under pressure to prevent. Alkali or gas leakage in the container 19, the cathode terminal 7 is welded on the anode seat 5, also can be welded on the container 19 or the pipe wall.

[0016] As shown in FIG. 2 , the auxiliary anode 17 is composed of a bracket 8 , an insulating pad 9 , a fixing bolt 10 , an insulating pad 11 , and an anode connecting coil 12 . The anode connecting coil 12 is a ring st...

Abstract

The invention relates to a corrosion proof alkaline water electrolytic hydrogen production device container that includes extra current corrosion proof device, which is made up of anode joint, assistant anode and constant voltage or constant current powder supply. The anode joint is made up of anode connector, insulating mat, anode holder, clamp nut and cathode connector. The assistant anode is made up from stand, insulating mat, fixation bolt and anode connecting coil that connects to the anode connector to form anode. Anode connects to positive pole of constant voltage or constant current powder supply. And the negative pole of constant voltage or constant current powder supply is connected to the cathode connector. The invention could fully avoid corrosion.

Description

(1) Technical field [0001] The invention relates to an anti-corrosion alkaline water electrolysis hydrogen production device container. (two), background technology [0002] Container corrosion of alkaline water electrolysis hydrogen production equipment is a common problem. Whether it is domestic equipment or imported equipment, there are different degrees of container corrosion problems. Corrosion is generally concentrated in the liquid phase part of the oxygen separator, lye heat exchanger and alkali Liquid filter, some also occur on the liquid phase, pipeline and joint of the hydrogen separator, this is because the liquid phase part of the container or the pipeline is filled with 25% to 30% NaOH or KOH strong alkali, plus the alkali solution Such as depolarizing O 2 and Cl - , during the operation, there is a weak current passing through the container and the pipeline to ground, so that electrochemical corrosion is very easy to occur in the stress concentration area or...
