Electrolysis device

Abstract

An electrolysis device of the present invention includes an electrolysis unit. The electrolysis unit includes a channel for fluid to be treated, at least one electrolysis electrode pair, a flow inlet, and a flow outlet. The electrolysis electrode pair is disposed so as to incline with respect to a vertical direction and includes an upper electrode and a lower electrode disposed so as to face each other. The channel for fluid to be treated is disposed so that a fluid that has flowed in from the flow inlet flows through an interelectrode channel between the upper electrode and the lower electrode from a lower side to an upper side and flows out from the flow outlet.

Description

TECHNICAL FIELD[0001]The present invention relates to an electrolysis device and particularly to a diaphragmless electrolysis device.BACKGROUND ART[0002]Electrolysis is practically used for, for example, production of chemical materials. Basic chemical raw materials such as sodium hydroxide (caustic soda), chlorine gas, hydrogen gas, and sodium carbonate (soda ash) are produced by, for example, an electrolytic soda process. In addition to industrial uses, an electrolysis technique is also used for home appliances such as an alkaline ionized water filter.[0003]The advantage of such an electrolysis technique is that an active substance can be produced from a harmless material having almost no activity. For example, hypochlorites such as sodium hypochlorite is used as a bleaching agent and a germicide for treating clean and sewage water, for treating a drain, and for household kitchens and washing. Hypochlorites are produced by a method in which an alkali hydroxide obtained by electrol...

Benefits of technology

The present invention is an electrolysis device that efficiently produces electrolysis products. The device includes an electrolysis unit with a channel for fluid to be treated, electrolysis electrodes, and a flow inlet / outlet. The electrodes are positioned so that a fluid flows through an interelectrode channel, from lower to upper, allowing for efficient production of electrolysis products. The device also includes an inclined electrode pair and a channel that facilitates the flow of fluid, resulting in improved production efficiency of electrolysis products.

Problems solved by technology

However, when the concentration of an aqueous hypochlorite solution produced by electrolysis is low, the concentration of an organic material contained in water to be treated is sometimes increased, or an object to be disinfected to which a relatively large amount of an organic material adheres cannot be sometimes sufficiently disinfected.

However, a long hold time decreases the production amount per unit time, and use of multistage electrodes degrades the productivity and increases the cost.

Furthermore, when these methods are employed, a large amount of hydrogen gas is generated.

However, use of such an acidic aqueous hypochlorite solution tends to generate chlorine gas in addition to hydrogen gas.

In such a configuration, however, the flow velocity of an electrolysis solution around the center of an interelectrode channel is high, and the flow velocity of an electrolysis solution around the ends is low.

Therefore, the time for which the electrolysis solution is electrolyzed varies depending on the paths through which the electrolysis solution flows, which decreases the production efficiency of an electrolysis product.
