Problems solved by technology

[0004] At present, the electrode frame used in the filter press bipolar electrolyzer is made of iron material, resulting in a large overall weight of the electrolyzer (the electrode frame used in the filter press bipolar electrolyzer is composed of many small air chambers). The number corresponds to the air chamber), which makes the assembly and sealing of the electrolyzer difficult

Abstract

The invention discloses a carbon fiber electrode frame and a diaphragm for a filter pressing type bi-electrode electrolysis cell. The electrolysis cell is composed of frame plates at two ends and foot margins which are integrated into a whole; a plurality of tensioning screw rods are arranged at the periphery of each frame plate and are used for fastening and clamping the frame plate; the upper part of each of the frame plates at the two ends are provided with an air output port (5); two sides of a bi-anode plate are respectively provided with a plurality of small electrolysis chambers; the bi-anode plate and the plurality of small electrolysis chambers are arranged according to electrical property and are compacted together in a in series connection manner, and the bi-anode plate is provided with an anode bolt wiring port; a carbon fiber electrode frame, a bi-electrode plate, a negative electrode net, a sealing gasket, a positive electrode net, another bi-electrode plate, and another carbon fiber electrode frame are overlapped and arranged in sequence in each small electrolysis chamber; the sealing gasket is compacted with the inner circumference surfaces of the carbon fiber electrode frames and is also compacted with the outer circumference surfaces of the diaphragm, the bi-electrode plate, the negative and positive electrode nets; and each carbon fiber electrode frame is made from carbon fiber, and the diaphragm is made from carbon fiber and glass fiber in a laminating way. According to the carbon fiber electrode frame and the diaphragm, the weight of the electrolysis cell is greatly reduced, and the assembling is convenient.

Description

technical field [0001] The invention relates to an electrolytic cell, in particular to a carbon fiber electrode frame and diaphragm for a filter press type bipolar electrolytic cell. Background technique [0002] The filter press bipolar electrolyzer is a device for producing hydrogen and oxygen by electrolysis of water. The chemical reaction is completed in the electrolytic cell. The electrolytic cell is the most basic unit of the electrolytic cell. It is composed of many electrolytic cells. These electrolytic chambers are tightly pressed between two end pressure plates through several tensioning screws. [0003] Chinese patent CN202430295U disclosed a filter press type bipolar electrolyzer on September 12, 2012, figure 1 The schematic diagram of its electrolyzer structure, figure 2 It is a schematic diagram of the arrangement sequence of the electrode frame, double electrode plate, negative electrode net, sealing gasket, small air chamber diaphragm, positive pole net, d...
