Scale inhibitor dosing system

DAWT·2022-05-09

System Introduction

The scale inhibitor dosing device is composed of a dosing pump and a dosing tank. It can realize the timing and quantitative automatic control of the added medicament, and can also realize the automatic alarm function of the liquid level. The equipment is simple, easy to operate, high-speed and flexible, and reliable in performance. The equipment is mainly used for industrial and civil water supply treatment, boiler water supply treatment, swimming pool water treatment, industrial circulating water treatment and various waste water treatment. Applicable to: coagulant, neutralizing acid and alkali, descaling agent and dispersing agent, disinfectant, oxygen scavenger, and water treatment agent and other water treatment agents. The device mainly includes four parts: the liquid medicine dissolving system, the metering and dosing system, the safety system and the control system. The solid or liquid medicine is added into the medicine dissolving box, and then industrial water is added in proportion to stir and dissolve, and then it is added to the medicine injection point by the metering and dosing system. Dosing control can be done manually, or according to the control signal output by the upper system. Follow-up control, automatic dosing. It has the following characteristics, stable performance, large volume of the dissolving tank, low energy consumption; beautiful appearance, compact structure, small landing area; convenient operation, simple maintenance, and strong external combination ability.

How it works

During the natural operation of the industrial circulating cooling system, scaling or corrosion tendency will occur due to the comprehensive influence of the cycle hardness, alkalinity, PH value, concentration multiple, air temperature, ambient humidity and other factors, both of which will affect the safety and operation of the circulating cooling system. Efficiency is adversely affected, in order to inhibit scaling or corrosion from occurring. It is necessary to manually add corrosion inhibitors or scale inhibitors to the water. Commonly used corrosion and scale inhibitors include polyphosphates, zinc salts, polycarboxylates and phosphates, among others.
