Process principle of circulating water dosing device

Process principle

Process principle of circulating water dosing device : When the industrial circulating cooling system is in natural operation, it will cause scaling or corrosion tendency due to the combined effects of the hardness, alkalinity, pH value, concentration multiple, temperature and environmental humidity of the circulating water. The safety and operating efficiency of the circulating cooling system will have an adverse effect on production. In order to suppress scaling or corrosion, it is necessary to manually add a corrosion inhibitor or a scale inhibitor to the water. Commonly used corrosion inhibitors and scale inhibitors include polyphosphates, zinc salts, polyhalogenates and linoleic acid salts, and the like.

Process overview

The device mainly includes four parts: a liquid medicine dissolving system, a metering and dosing system, a safety system and a control system. The solid medicament is added to the solvent tank, and then added to the industrial water by stirring to dissolve, and is added to the administration point by the metering and adding system. The feeding control is manual, and the follow-up control can be performed according to the control signal outputted by the upper system, and the automatic feeding is performed.
