Product composition:
Feeding system, reaction system, control system, vacuum absorption system
Safety system, backwash system.

Raw materials used:
Sodium chlorate (industrial grade 1, content 99%)
Hydrochloric acid (industrial synthetic grade 1, concentration 31%)
Reaction principle:
2NaCIO3+4HCI=2CIO2+CI2+2NaCI+2H2O

Application of working conditions:
Hospital wastewater contains a large amount of viruses, bacteria, parasite eggs, and some toxic and harmful substances. Disinfection is an important part of hospital wastewater treatment. At present, the disinfectants used in domestic hospitals are mainly liquid chlorine and sodium hypochlorite. Although liquid chlorine is relatively inexpensive, it is prone to leakage and has poor safety. Moreover, the interaction between chlorine and organic matter can generate organochlorine substitutes, which can cause new pollution and threaten human health when entering water bodies; Although the electrolytic sodium hypochlorite generator does not have the above hazards, its key components are easily damaged, the volume is large, and the operating costs such as power consumption and salt consumption are high. Chlorine dioxide has been recognized by the World Health Organization (WHO) as a safe and efficient potent fungicide. Its effective chlorine content is 2.63 times that of chlorine gas, its bactericidal ability is 5 times that of chlorine gas, and more than 50 times that of sodium hypochlorite. It has a sterilization rate of 100% against pathogenic microorganisms, bacteria, parasite eggs transmitted through water, and has a good killing effect on highly chlorine resistant viruses, spores, fungi, etc. Chlorine dioxide can also react with some organic compounds in wastewater and has good odor removal function.

Performance characteristics:
Automatic constant temperature control, with a controlled temperature of up to 75 ℃.
The self circulating negative pressure aeration reaction process has a reaction yield greater than 82%.
The reactor is made of composite materials or imported special materials, which are temperature resistant, corrosion-resistant, have a long service life, and excellent thermal conductivity.
Simulation control system, touch sensitive operation panel, equipped with safety protection functions such as constant temperature control, material shortage, water shortage, under voltage, over temperature alarm, and automatic shutdown.
Imported metering pump for feeding, with high measurement accuracy.
The imported back pressure valve controls a constant back pressure to ensure the accuracy of feed measurement and prevent the self flow or siphon formation of the liquid medicine.
Prepare a composite disinfectant with a CIO2 content greater than 70% based on effective chlorine.
The internal and external automatic pressure relief safety system ensures the safety and reliability of the equipment.
It has a backwash function.

Raw material consumption:
Producing 1 gram of effective chlorine consumes 0.65 grams of sodium chlorate and 1.3 grams of hydrochloric acid. Equivalent to RMB 0.004. (Note: Hydrochloric acid is calculated at 800 yuan/ton, sodium chlorate is calculated at 4200 yuan/ton)

matters needing attention:
This product is suitable for water treatment facilities under normal pressure (or slightly positive pressure) conditions.
Users are required to provide on-site power sources, power supplies (~380V/220V), drainage ditches, and low-level exhaust facilities.
In special circumstances, the diameter of the disinfectant injection pipe should be selected according to the site conditions (such as pipeline back pressure).
