Background technique

In the production process of electrolytic sodium hypochlorite equipment, salt water with a certain concentration and flow rate is required as a raw material, and a certain concentration of sodium hypochlorite solution is generated after electrolysis by electrodes.

In the current existing technology, the flow rate and brine concentration are easily disturbed by external factors, which makes the salt mixing effect difficult to stabilize. Therefore, the electrolysis efficiency is high and low, and the concentration of the sodium hypochlorite solution generated is also high and low, resulting in low equipment efficiency. Dosing The impact on the instability of the disinfection effect of the water body.

Through the above adjustments, the flow and concentration of the brine entering the electrolysis device 4 can always be kept at an optimal value.
