Small knowledge of chlorine dioxide dosing device

Chlorine dioxide dispenser is a device used for water treatment, which utilizes the reaction principle of chlorine dioxide for disinfection. Chlorine dioxide (CIO2) is a strong oxidant with high bactericidal and oxidizing abilities, widely used in fields such as water treatment and sanitation disinfection. The reaction principle of chlorine dioxide dosing device mainly includes two aspects: the generation of chlorine dioxide and its disinfection effect. The generation of chlorine dioxide is obtained by reacting chlorine gas with sodium chloride (NaCl) or sodium hypochlorite (NaCIO) solution.

working principle

Chemical method for generating chlorine dioxide: The common reaction principle is to react sodium chlorate with hydrochloric acid, or sodium chlorite with hydrochloric acid to generate chlorine dioxide. For example, sodium chlorate reacts with hydrochloric acid under acidic conditions to produce chlorine dioxide, chlorine gas, sodium chloride, and water,

Measurement and dosing: Using a metering pump to accurately control the dosage of chlorine dioxide solution, adjust the operating frequency or stroke of the metering pump according to the amount and quality of water that needs to be disinfected or treated, in order to achieve accurate dosing of chlorine dioxide.

structural composition

Feeding system: including storage tanks, metering pumps, etc., used to store chlorine dioxide raw material solution and transport it to the reaction system or directly add it to the water to be treated.

Reaction system: If chlorine dioxide is generated through a chemical reaction, the reaction system is a key component, usually composed of reaction vessels and other equipment, providing suitable reaction conditions to fully react the raw materials to generate chlorine dioxide.

Control system: Intelligent controllers are generally used, which can achieve manual control, automatic control, residual control, flow control, dual control of residual flow, remote control and other functions to monitor and adjust the operation of the dosing device, ensuring the stability and accuracy of the dosing process.

Mixing system: The generated chlorine dioxide solution is thoroughly mixed with the water to be treated, so that chlorine dioxide can be evenly distributed in the water, exerting disinfection and treatment effects.

Safety system: equipped with gas leak alarms, safety valves, explosion-proof devices, etc., when the pressure inside the equipment is too high or chlorine dioxide gas leaks, it can promptly issue an alarm and take corresponding safety measures to ensure the safety of equipment and personnel.

Performance Characteristics

Accurate dosing: It can accurately control the dosage of chlorine dioxide according to the set parameters, ensuring disinfection effectiveness while avoiding problems of excessive or insufficient dosing, which can effectively save drug costs.

High degree of automation: It has multiple automation control functions, such as automatic online feeding, automatic adjustment of production amount based on water volume or residual chlorine, etc., reducing the workload and errors of manual operation, improving work efficiency and operational stability.

Good sterilization effect: Chlorine dioxide has strong oxidizing properties and has a broad-spectrum killing effect on bacteria, viruses, algae and other microorganisms in water. It can effectively eliminate pathogenic microorganisms in water sources and ensure water quality safety.Small knowledge of chlorine dioxide dosing device

No secondary pollution: The addition of chlorine dioxide does not produce toxic by-products, has a minimal impact on the environment, does not lower the pH value of water, and can effectively improve the taste of water.

Strong corrosion resistance: Due to the corrosiveness of chlorine dioxide, corrosion-resistant materials such as titanium alloy, polytetrafluoroethylene, etc. are usually selected for the material of the dosing device to ensure the service life and safe operation of the equipment.

Application scenarios

Drinking water treatment: used for disinfection, deodorization, iron removal, manganese removal, etc. in water plants, small self owned well water supply, secondary water supply, etc., to ensure the hygiene and safety of drinking water.

Wastewater treatment: Online sterilization and disinfection can be carried out on sewage, domestic sewage, industrial wastewater, etc. to reduce the microbial content in sewage and meet discharge standards.

Industrial circulating cooling water system: It can kill bacteria, algae, fungi and other microorganisms in circulating water, prevent pipeline corrosion, scaling and other problems caused by microbial growth, and improve the utilization efficiency of circulating cooling water.

Food processing industry: used for purifying and disinfecting water used in food processing, disinfecting food processing equipment and environment, etc., to ensure the hygiene and quality of food.
