Analysis of dosing equipment in circulating water system

A complete dosing equipment shall be composed of a feeding system, a stirring system, a batching system, a dosing system and a control system.




The composition of dosing equipment depends on the type, form and concentration of dosing agent.




According to the types of agents, the conventional water quality stabilizing agents in the circulating water system include corrosion inhibitor, scale inhibitor, dispersant, fungicide, coagulant, coagulant aid and pH adjusting acid and base.




According to the form of agents, there are powdery agents and liquid agents, in order to facilitate the transport of agents, used in the circulating water system of agents to powdery agents, pH adjustment of the acid base for liquid agents; Coagulants (PAC) are usually powdery agents with a mass fraction of about 28%, and coagulants (PAM), corrosion inhibitors, scale inhibitors, and dispersants are usually powdery agents with a mass fraction of about 90% > : fungicides with a mass fraction of about 92% of chloroprene, and sodium hypochlorite with a mass fraction of about 15%. With regard to the dosage of mass fraction, the dosage of coagulant (PAC) is 15%, coagulant aid (PAM) is 0.15%, corrosion inhibitor, scale inhibitor and dispersant is 1%. The fungicide is 2% ~ 3%. Inhibitors, scale inhibitors, fungicides used for stable net circulating water quality, such as corrosion inhibitors, scale inhibitors, fungicides, etc., due to the small amount, taking the circulating water of 9000mS/h as an example, the demand for corrosion inhibitors and scale inhibitors is about 20-50mg/L(according to the amount of water replenishing), and the dosage is about 10(the mass fraction of agents is about 30%-50%). So liquid agents can be used
