1Overview of Hospital Laboratory Sewage Treatment Equipment

1. Product features, main applications, and scope of use
The chlorine dioxide water disinfectant generator is a high-tech product developed and produced by Shandong Okunlai Intelligent Technology Co., Ltd. The product uses a chemical process to prepare a mixed disinfectant solution of chlorine dioxide from sodium chlorate and hydrochloric acid, which can be widely used for disinfection of drinking water, swimming pools, and hospital sewage; Industrial circulating cooling water for sterilization and algae removal; Industrial wastewater decolorization, deodorization, or removal of reducing pollutants.
2. Composition and representative significance of specifications and models
The specifications of the generator are divided according to the effective chlorine production per hour (g/h) of the equipment. For example, HY-500 g/h refers to the maximum effective chlorine production per hour of the product, which is 500 grams.
3. Operating environment and working conditions
Location: Indoor (well ventilated)
Water source matching: pipe diameter and corresponding water injector matching; Water pressure: 0.2-0.3MPa
Power supply: AC 220V, 380V, 50HZ

IIHospital laboratory sewage treatment equipmentWorking principle
（1） Overall structure and working principle
Overall structure: The generator consists of a feeding system, a reaction system, a control system, and a safety system. The generator casing is made of PVC material.
Working principle: Sodium chlorate aqueous solution and hydrochloric acid solution are input into the reactor by a metering pump, and undergo sufficient reaction at a certain temperature and negative pressure to produce disinfection supplemented by chlorine dioxide. After being absorbed by a water injector and fully mixed with water to form a disinfectant solution, it is introduced into the disinfected water.
（2） Main component functions and working principles
(1) Water jet injector: A water jet injector is a type of air extraction component designed based on the principle of jet flow. When power water passes through the water jet injector, negative pressure is generated inside, and external gas is sucked into the water jet injector under the pressure difference, thereby achieving suction. The inhaled chlorine dioxide is mixed with some to form a disinfectant, and the water sprayer is also used for absorption in the raw material tank.
(2) Metering pump: conveying raw materials and regulating flow rate.
(3) Reflector aeration port [air inlet]: an air channel for equipment operation. During installation, it can be connected to a pipeline and open to the outside, while maintaining communication with the atmosphere.
(4) Electric contact pressure gauge: An electric contact pressure gauge is one of the devices that protect the safe operation of equipment. Its working principle is that when the water pressure at the front end of the water injector is lower than the set value, the gauge controls the metering pump to stop feeding.
(5) Raw material level sensor: The raw material level sensor is also one of the devices that protect the safe operation of equipment. It is installed at the bottom of two raw material tanks. When any one of the raw materials is used up, the metering pump will stop feeding.
(6) Temperature controller: The temperature controller is the heating control mechanism of the system, which ensures the chemical reaction temperature between sodium chlorate and hydrochloric acid.
(7) Controller: The controller is the control core of the chlorine dioxide generator, which completes the entire automatic control of the system.
