What are the main types of chlorination devices

What are the main types of (pleated filter element) chlorination devices? How does it work? There are many types of chlorination devices, such as rotor chlorinators, vacuum chlorinators, hydraulic injection chlorinators, etc. The most commonly used in China is the ZJ rotor chlorinator. There are two types of Type I (chlorination amount 5~45kg/h) and Type II (chlorination amount 2~10kg/h) at present. Its working principle is: the chlorine gas from the chlorine bottle first enters the cyclone separator 3, and then enters the rotameter 4 and the transfer glass cover 5 through the spring membrane valve 1 and the control valve 2, and then is mixed with the pressure water by the water ejector 7. The chlorine gas is dissolved in water and sent to the chlorination point. ZJ type rotor chlorinator 1—spring membrane valve; .2—control valve; 3—cyclone separator; 4—rotameter; 5—transit glass cover; 6—balanced water tank; : Spring membrane valve 1, when the pressure in the chlorine bottle is less than a certain pressure (such as 0.1MPa, 1kgf/cm2), this valve is automatically closed to ensure the safety requirements of maintaining a certain residual pressure in the chlorine bottle. Control valve 2 and rotameter 4 are used to control and measure the amount of chlorine added. Cyclone separator 3, the pleated filter element is used to separate some impurities that may be brought in in the chlorine gas. After running for a certain period of time, the lower cock of the separator should be opened to remove accumulated impurities. The transfer glass cover 5 is used to observe the working condition of the chlorinator. In addition, it can stabilize the amount of chlorine added, prevent the pressure water from flowing backwards, and avoid breaking the vacuum in the cover when the water source is interrupted. The balance water tank 6 can supplement and stabilize the water level in the transfer glass cover, and avoid the vacuum damage of the transfer glass cover when the water flow is interrupted. The water ejector 7 sucks the required chlorine from the intermediate glass cover, and mixes it with water to dissolve the chlorine gas. At the same time, it can also keep the negative pressure in the glass cover.
