[0002] GB50045 "Code for Fire Protection Design of High-Rise Civil Buildings" stipulates that "residential buildings with ten floors or more" and "public buildings with a building height of more than 24m" are all industrial buildings. Industrial buildings have high requirements for the reliability of fire protection systems due to factors such as the large number of floors, the large number of residents, the rapid spread of fire, and the difficulty of fire fighting. Industrial buildings mainly rely on indoor fire fighting facilities to fight fires. The fire water system of industrial buildings needs to be able to provide enough high-pressure fire water for fire fighting when a fire accident occurs. Therefore, the fire water system of industrial buildings needs to have high reliability. Corrosion is a common problem in fire water systems. Once this problem develops into pipe perforation, it will seriously threaten the reliability of the fire water system. Once a fire occurs, it will cause serious economic and personnel losses.

[0003] The cause of corrosion in fire water systems is closely related to pipe material, water quality and operation mode. The main types of corrosion are oxygen corrosion and microbial corrosion. The corrosion of fire water systems can be controlled by adding anti-corrosion agents. Existing anti-corrosion dosing devices generally require solid drugs to be mixed outside the dosing device before being placed in the dosing device for dosing operations, which is inconvenient for workers to operate and is time-consuming and laborious.

[0004] In view of the above problems, we propose an anti-corrosion and dosing device for fire water pipes in industrial buildings. Utility Model Content
