Open-cell type apparatus for preparing sodium hypochlorite

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.

What is claimed is: 
     
         1 . An open cell-type apparatus for producing sodium hypochlorite based on electrolysis using soft water and salt, the apparatus comprising:
 a sodium hypochlorite generator including a plurality of electrode plates  25  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, the cooling unit being connected to the air intake hole; and   a controller for controlling operation of the cooling unit by detecting a temperature of the sodium hypochlorite generator,   wherein the sodium hypochlorite generator includes a guide which is provided above an air intake pipe connected to the flow channel and guides air flow.   
     
     
         2 . The open cell-type apparatus according to  claim 1 , further comprising a sodium hypochlorite collection tank equipped with a heat exchanger, the sodium hypochlorite collection tank being installed at a downstream of a sodium hypochlorite discharge pipe of the sodium hypochlorite generator, and controlling a temperature of the soft water. 
     
     
         3 . The open cell-type apparatus according to  claim 1 , wherein the cooling unit uses a fan. 
     
     
         4 . The open cell-type apparatus according to  claim 1 , wherein the cooling unit uses an air condenser interlocking with an air compressor. 
     
     
         5 . The open cell-type apparatus according to  claim 1 , wherein the cooling unit uses an air cooler interlocking with an indoor unit. 
     
     
         6 . The open cell-type apparatus according to  claim 1 , wherein the cooling unit uses an ice cooling fan. 
     
     
         7 . The open cell-type apparatus according to  claim 1 , further comprising a backflow preventing unit for intercepting air flow, which is provided above an air intake pipe connected to the flow channel of the sodium hypochlorite generator,
 wherein the backflow preventing unit is selectively provided with a baffle plate, a sheet, and an electric damper.   
     
     
         8 . The open cell-type apparatus according to  claim 1 , wherein the controller controls the temperature of the soft water by causing a control board to receive temperature changes of the sodium hypochlorite generator and maintains the temperature of the flow channel within a preset range.
