Product Overview
This product adopts ion-exchange membrane electrolysis technology to stably produce NaOH with a concentration of 30%-32%. According to the required output, the NaOH obtained from salt water electrolysis will be passed through an evaporator to obtain caustic soda of different concentrations (32%, 50%, 60%, 99%). The evaporator is made of N02201 pure nickel heat exchange tube + nickel-steel composite plate cylinder. The whole system adopts skid-mounted design and is equipped with a full PLC automatic control system. The concentration of the obtained caustic soda can be customized according to user needs.
System Process Flow
1. Brine Preparation Unit
Industrial refined salt enters the salt saturator and mixes with water to form saturated brine.
2. Multi-stage Filtration and Purification System
The brine goes through multi-stage filtration and purification to remove impurities in the water.
3. Core Reaction in Ion-exchange Membrane Electrolyzer
After purification and filtration, the brine enters the ion-exchange membrane electrolyzer and then flows into the anode chamber. There is an ion-exchange membrane in the anode chamber that allows sodium ions to enter the cathode chamber while blocking chloride ions. Chloride ions are electrolyzed in the anode chamber to generate chlorine gas. Sodium ions and water are electrolyzed in the cathode chamber to generate sodium hydroxide and hydrogen. At the same time, the chloride ions in the anode chamber also react with the residual sodium ions to generate sodium chloride, which can be recycled after dechlorination and denitration.
4. NaOH Solution Entering Open Pan or Evaporator
We provide customized services according to the caustic soda concentration required by customers. The evaporator made of N02201 pure nickel heat exchange tube + nickel-steel composite plate cylinder delivers higher production capacity. If users need caustic soda flakes, a flaker is required to produce the flake product.
5. Pickling System for Electrolyzer Pickling
The electrolyzer is pickled with hydrochloric acid at a concentration of 8% to remove calcium and magnesium ion precipitates generated during the reaction, prevent scaling, and extend the service life of the electrolyzer.
6. Ventilation System
A fan is used to dilute the hydrogen generated from the reaction before venting it out to ensure safety.
