Problems solved by technology

[0005] However, the conventional device for preparing sodium hypochlorite has the following problem: Since heat is generated in the electrolytic cell during the electrolysis of light brine, the temperature of the obtained sodium hypochlorite rises to 30 minutes after the operation of the conventional device starts. Higher than the optimum temperature of brackish water, and the concentration of available chlorine will decrease with the operation time of traditional units

Embodiment Construction

[0027] Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings.

[0028] The apparatus for producing sodium hypochlorite according to the present invention employs electrolysis using soft water and sodium. When using conventional manufacturing equipment, due to the heat generated during the electrolysis process, the temperature of the produced sodium hypochlorite rises to 40°C to 50°C, which is 25°C to 35°C higher than that of light brine. This high temperature reduces the concentration of available chlorine and thus hinders the formation of high concentrations of sodium hypochlorite. In view of such circumstances, the object of the present invention is to implement a technique for uninterrupted production of high-concentration sodium hypochlorite by performing electrolysis at a controlled temperature in a manner using an open-type device without a membrane.

[0029] According to the present invention, the sodiu...

Abstract

Provided is an open cell-type apparatus for producing sodium hypochlorite based on electrolysis using soft water and salt. The apparatus includes: a sodium hypochlorite generator including a plurality of electrode plates supported by a support, a flow channel for air flow provided above the support and the electrode plates, and an air intake hole and an air exhaust hole which communicate with the flow channel; a cooling unit for lowering a temperature of the flow channel; and a controller for controlling operation of the cooling unit by detecting a temperature of the sodium hypochlorite generator. The apparatus constantly maintains an optimum temperature of the sodium hypochlorite generator in order to produce sodium hypochlorite of a high concentration with high efficiency.

Description

technical field [0001] The present invention relates to an apparatus for the production of sodium hypochlorite (NaOCl), and more particularly, to an open-type apparatus for the production of sodium hypochlorite capable of reducing the hardness of cations deposited on the cathode and by maintaining Constant optimal temperature to improve electrolysis efficiency. Background technique [0002] Generally, chemical disinfection or ozone disinfection is used as a disinfection method for water treatment plants, sewage treatment plants, swimming pools, large barns, contract foodservices, etc. However, in many cases, we are reluctant to use these methods for some reasons. For example, because these disinfection methods are not economical (due to the need to use expensive chemicals) or because they are not environmentally friendly (due to the use of hazardous chemicals and the formation of chemical residues). In particular, in the case of disinfection using ozone, there are problems...
