The dosing device adopts an electromechanical-integrated structure. From the installation, it can be divided into fixed and mobile (trolley type). Each type of dosing device is equipped with a mixing system, a dosing system and an automatic control. system. Several fixed skids can be combined into a whole, plus a frequency conversion control system, which can realize local control, remote automatic control, manual and automatic conversion and dosing. It has the advantages of compact structure, small size, low noise, stable work, simple installation, and convenient operation.

Analyze what problems are prone to occur in the circulating water system of the dosing device:

1. Corrosion: When cooling water is in circulation, the water is in good contact with the air in the automatic dosing device, so that the dissolved oxygen in the water is too saturated, and the dissolved oxygen in the water will cause corrosion of metal pipes such as carbon steel and cast iron.

2. Scaling: The continuous evaporation of water in the automatic dosing device greatly increases the salt content in the circulating water, and the calcium carbonate and carbonate in the water greatly increase, resulting in scaling on the pipe surface and uneven heat transfer on the surface.

3. Sludge: The cooling water absorbs a large amount of dust, sand, microorganisms and other inorganic and organic substances in the air. Because the light, temperature and oxygen in the cooling tower are all suitable for the growth of bacteria and algae, the sludge in the system is increased. Cause system hazards.
