Embodiment Construction

[0007] figure 1 It is the DC circuit diagram of the sodium chlorate electrolysis device and the setting of the leakage current stopper. The silicon rectifier 7, the conductive busbar 5, and the electrolytic cell 3 constitute the main electrolysis circuit, and the corresponding electrolyte pipeline solution forms a leakage current loop, which is divided into the upper pipeline solution current loop and the lower pipeline solution current loop.

[0008] I total = I electrolysis +I Solution

[0009] I Solution (i) =ΔV(i) / R Solution (i) I Solution =∑I Solution (i)

[0010] Where: ΔV(i) is the ground potential of the i-th electrolytic cell

[0011] R Solution (i) Is the pipe solution resistance of the i-th electrolytic cell

[0012] I Solution (i) Is the solution leakage resistance of the i-th electrolytic cell

[0013] After the electrolysis device is connected to direct current, H 2 , Forming lift force, make the electrolytic solution and H 2 The mixed liquid enters th...

Abstract

The invention relates to a stopper aiming to arrange a pipeline drain current stopper in an electrolyte collecting pipe of an electrobath in the chemical industry so that the stopper only stops the current instead of the flowage of an electrolyte. The stopper structurally comprises a multi-blade rotary wheel (10) which is mounted in a pipe and automatically rotates along with the flowage of the electrolyte (15) in a pipeline. The blades of the rotary wheel are made from an insulation material, form little gaps with the insulation lining wall of a pipeline inner wall (9) and are in multi-blade structure so that the total resistance of the electrolyte in the pipeline along a pipeline axis is increased, a drain current passing through the electrolyte in the pipeline is greatly decreased, and the electricity-saving aim is achieved.

Description

Technical field [0001] The invention aims to reduce the leakage current of the electrolyte pipeline solution of the electrolysis device in the chemical industry, reduce corrosion and power consumption, and belongs to the field of chemical equipment. Background technique [0002] The direct current used in the electrolysis of the chemical industry enters the electrolytic cell from the positive electrode through the conductive copper (aluminum) row, and the electrochemical reaction is carried out at the anode and the anode to obtain the desired product or intermediate. The direct current flows from the cathode of the last cell to the negative electrode to form a DC circuit. Electrolyte solutions belong to the second type of conductors, which conduct electricity by ion migration, and their resistivity is much greater than that of metal conductors. The electrolyte pipeline is connected to each electrolytic cell, and the electrolytic cells at different positions have different potenti...
