With the increasing scarcity of global freshwater resources and the growing demand for sustainable development, developing and utilizing abundant seawater resources has become an important strategic choice for many countries and regions. Among them, electrolytic seawater equipment, as a key technology, has shown great potential in multiple fields such as seawater desalination and resource extraction.

1、 Overview of seawater electrolysis equipment

(1) Definition and Principle
Electrolytic seawater equipment is a device that uses electrochemical methods to electrolyze seawater to achieve specific purposes. The basic principle is that under the action of direct current, salts such as sodium chloride contained in seawater undergo ionization reactions in the electrolytic cell. Taking the preparation of sodium hypochlorite as an example, on the anode, chloride ions lose electrons and generate chlorine gas; On the cathode, hydrogen gas will be released or hydroxide ions will be generated. If controlled properly, a high concentration and stable sodium hypochlorite solution can be obtained, which has strong oxidizing properties and can be widely used in water treatment, disinfection and sterilization fields.

(2) Main components

1. Power control and rectifier system
Providing a stable and reliable DC power supply is the key to ensuring the smooth progress of the electrolysis process. Modern seawater electrolysis equipment usually uses high-efficiency and energy-saving rectifiers, which can accurately adjust the output voltage and current according to actual needs.

2. Electrolytic cell
This is the core site of electrolytic reactions. In order to improve electrolysis efficiency and reduce energy consumption, the new electrolytic cell is made of special materials such as titanium based coated electrodes, which not only have strong corrosion resistance but also effectively reduce the occurrence of side reactions. Meanwhile, optimizing the design of the electrolytic cell structure is also beneficial for improving mass transfer conditions, making it easier to separate and collect electrolytic products.

3. Control system
Intelligent control systems are crucial for ensuring the safe operation of equipment. It can monitor various parameters in real-time, such as temperature, pressure, current density, etc., and automatically adjust operating conditions through feedback mechanism to ensure that the entire electrolysis process is in the best state. In addition, advanced control systems also have fault diagnosis and alarm functions, which can detect and solve problems in the first time, avoiding greater losses.
