Sodium chlorite+hydrochloric acid (sodium chlorite method) high-efficiency high-purity chlorine dioxide generator

1. In order to fully extend the reaction time of raw materials, improve the chlorine dioxide content and conversion rate of raw materials, the only multi-stage reactor in the same industry in China is used. The reaction time of raw materials in the reactor is over 45 minutes, and the total conversion rate of raw materials is ≥ 90%. The high-efficiency and high-purity chlorine dioxide generator of sodium chlorite method basically produces chlorine dioxide, which accounts for more than 95% of the total effective chlorine. This can greatly reduce the content of chlorate in the added medicine and avoid the phenomenon of excessive chlorate content found in tap water testing process in China.
2. The domestically pioneered dual reactor indirect water bag combined with dry heating method has fast heating, low power, stable temperature, lower power consumption compared to products in the same industry, and high raw material conversion efficiency.
3. The only direct measurement of the actual reaction temperature inside the reactor in China, with temperature control of 38 ± 2 ℃ and 75 ± 1 ℃.
4. The dual temperature control system developed for large-scale equipment can maintain a high raw material conversion rate for equipment used in cold regions.
5. The use of residual liquid separation devices can greatly improve the safety of drinking water.
6. The raw material transportation adopts imported electromagnetic metering pumps, which operate stably, measure accurately, and are safe and reliable.
7. The reaction kettle inside the equipment is made of high-temperature resistant and corrosion-resistant pure titanium (TA1) material through one-time mold forming, which has strong reliability and safety, completely avoiding the possibility of explosion and leakage of chlorine dioxide generator reaction kettle that occasionally occurs in China, ensuring the safety of equipment and operators, and ensuring a service life of more than 20 years.
8. Using Siemens industrial grade PLC (usually single-chip microcontroller in China) as the controller for chlorine dioxide generator, it has extremely high reliability and anti-interference ability, integrating temperature control, frequency regulation, flow control, residual chlorine control, and logic control.
9. The temperature control adopts Haoda Company's patented five level constant temperature PID temperature control technology to accurately control the temperature. Set the highest temperature cut-off self-protection function.
10. Using Siemens touch LCD screen as display and control, the LCD screen displays in real-time the process flow of chlorine dioxide production, the working status of each component, temperature, pressure, dosing parameters, etc., ensuring stable, safe, and efficient operation of the machine.
11. The safest operation: The specially customized explosion-proof device has reversible function, which can effectively release the excessive pressure inside the reactor and quickly recover on its own.
12. Based on user selection of raw material storage tanks that can last for 20 days or longer; The liquid level of large raw material tanks can be continuously measured and remotely monitored and controlled by an upper computer.
13. Facilitating the automation of device operation processes. It is very easy to implement linkage control with the device you require.
14. A good installation mode can ensure that there is no chlorine dioxide or corrosive gas present indoors, no noise or air leakage pollution.
15. Haoda's complete set of sodium chlorate chemical materials and storage tank integrated components can automatically dissolve sodium chlorate particles quickly. The storage tank is equipped with liquid level control, and after adding raw materials, it can automatically enter water and stop replenishing water for automatic dissolution;
16. The complete set of hydrochloric acid self-priming storage tank and acid mist absorption device from Haoda can automatically suck hydrochloric acid from the purchased acid tank into the hydrochloric acid storage tank, solving the problem of difficult acid addition in chlorine dioxide generators. At the same time, the integrated acid mist absorption device can absorb the acid mist generated when concentrated hydrochloric acid is sucked in, so that there is no acid mist in the generator room, ensuring the safety of operators;
17. Reaction equation:
5NaClO₂+ 4HCl(Thick)=4ClO₂↑ + 5NaCl + 2H₂O(Sodium chlorite method)
