What are the chlorine ammonia disinfection equipment?

Answer: The chlorine ammonia disinfection system is mainly composed of two parts. Part of it is chlorination equipment, which is exactly the same as the chlorination equipment system mentioned above. The other part is ammonia adding equipment. Ammonia adding system can be divided into liquid ammonia adding equipment and amine salt adding equipment according to different raw materials, in which liquid ammonia adding equipment includes positive pressure ammonia adding machine and vacuum ammonia adding machine. The vacuum ammonia dosing machine is the same as the above-mentioned vacuum chlorine dosing machine, but the composition materials are different, and the dosing equipment of amine salt is basically the same as the above-mentioned dosing equipment.

Positive pressure ammonia feeder generally consists of three parts: pressure regulator, ammonia flow control unit and one-way valve diffuser. Ammonia evaporation pipeline is similar to the positive pressure pipeline of chlorination system. In the past, due to the precipitation of calcium salt and manganese salt in water, the vacuum ammonia feeder was easily blocked by water jet, so it was selected by various water departments as a positive pressure ammonia feeder. The positive pressure ammonia feeder does not use water jet, and its rubber sleeve diffuser with self-cleaning function can effectively reduce the precipitation of calcium salt and manganese salt, which is not easy to block. However, the positive pressure ammonia adding machine is easy to leak and has poor safety.

With the development of vacuum ammonia adding machine technology and the improvement of its application level in domestic water departments, there is a reliable technology to solve the problem of water jet ammonia adding blockage. A new type of special double-headed water jet equipped with vacuum ammonia adding machine has effectively solved the problem of water jet blockage in ammonia adding application in Shanghai Waterworks.
