Electrolysis system without cell shell

Abstract

The invention discloses an electrolysis system without a cell shell. The electrolysis system mainly comprises steel fastening pressing plates, end face insulating plates, fastening screws, polar plates and an electric conducting device, wherein each polar plate mainly comprises end face polar plates, negative plates, positive plates and a single-sided coated plate; the polar plates are arranged between at least two steel fastening pressing plates; the end face insulating plates are arranged at the sides, close to the polar plates, of the steel fastening pressing plates; the steel fastening pressing plates are connected by the fastening screws; sealing grooves are formed on the peripheries of the polar plates; sealing gaskets are arranged in the sealing grooves; the orientations of openings of the sealing grooves in the polar plates are the same; the polar plates are tightly pressed between the steel fastening pressing plates via fastening nuts; the sealing gaskets are tightly pressed between the two adjacent polar plates; and a gap between the two adjacent polar plates forms a cavity for electrolyte to flow. The electrolysis system dispenses with the cell shell, is easy to assemble and disassemble, can be flexibly assembled according to the capacity, is adjustable in polar distance and has the effect of greatly improving the loading capacity and the electrolytic efficiency.

Description

technical field [0001] The invention relates to the technical field of electrolysis water treatment, in particular to a tankless electrolysis system, which can be widely used in drinking water disinfection, food industry disinfection and sterilization, municipal sewage treatment, printing and dyeing, medicine, chemical wastewater treatment, power plant cooling Water treatment, ship ballast water treatment and other fields. Background technique [0002] Existing electrolysis devices for various water treatment applications are mainly composed of tank shells (referred to as tanks), cathode and anode plates, conductive titanium copper-clad plates, conductive copper screws, etc. According to different shapes of tanks, electrolysis devices have various shapes, The electrolytic device commonly known as the sodium hypochlorite generator is mostly a vertical square structure, such as the Chinese patent "Network Transparent Electrolyzer" with the application number 99201387.9; the Ch...

AI Technical Summary

Problems solved by technology

[0003] 1. Both require a special tank to carry the electrodes and electrolyte. The electrodes are installed in the tank. The tank is made of PVC, PP and other plastics. The body and size of the electrode plate are suitable, and the corresponding titanium-clad copper conductive plate needs to be processed and ordered, which is cumbersome to manufacture and assemble;

[0004] 2. The pressure of the tank body is small, such as the patent "A New Nano Catalytic Electrolysis Device", the working pressure is a slight positive pressure or a slight negative pressure; the working pressure of a general sodium hypochlorite generator cannot exceed 0.2MPa, and the tubular electrolytic seawater chlorine production device The maximum pressure is 0.4MPa, overpressure will cause deformation or leakage;

[0005] 3. The pole plate (end plate) is welded on the titanium-clad copper conductive plate. After the pole plate is punched, it is fixed together with a long plastic screw and the pole distance is maintained by a plastic gasket. Installation, disassembly and maintenance are very troublesome.

Therefore, online cleaning and descaling or electrode descaling can only be used. The above two methods will cause varying degrees of damage to the plates and shorten the service life of the plates. , inconvenient to replace

[0006] 4. The existing electrolysis device has a small amount of chlorine output per unit, and the effective chlorine output is less than 20Kg / h. If a larger chlorine output is required, a series or parallel combination of multiple devices is usually used, which occupies a large area of ​​the site and requires management and maintenance. trouble;

[0007] 5. In the process of manufacture and assembly, there is often a gap between the tank body and the electrode plate, and there is a non-electrolytic area, which causes some liquid to pass through the non-electrolytic area directly without being electrolyzed, resulting in a decrease in electrolytic efficiency
