加药装置
Dosing Device

    加药装置是一种具投药、搅拌、输送液体、自动控制与一体的成套设备，它被广泛应用于电厂的原水、锅炉给水、油田地面集输脱水处理系统，石油化工各种加药系统和废水处理系统。如投加混凝剂、酸碱溶液、磷酸盐、氨液、氧化剂、还原剂、水质稳定剂（缓蚀剂）、阻垢剂等。

工作原理
    加药装置主要由溶液箱、搅拌箱（带搅拌器）、计量泵、液位计、电控柜、管路、阀门、安全阀、止回阀、压力表、过滤器、底座、扶梯等组成。
    加药装置根据所需药剂浓度，在搅拌箱内配制，经搅拌器拌均匀后投入溶液箱、用计理泵（加药泵）向投药点或指定的系统中输送所配制的溶液。成套加药装置具有结构紧凑、安全简单、操作使用简便等特点。

Dosing device is a site of dosing, mixing, transporting liquids, automatic control and one of complete sets of equipment, it is widely used in power plant water, boiler water supply, transportation and storage of oil field surface dehydration systems, petroleum and chemical dosing systems and wastewater treatment systems. Dosing of coagulants, phosphates, ammonia solution, acid and alkali solution and oxidant, reductant, water stabilizer (inhibitor), scale inhibitor, etc.

Working principle
Dosing device mainly consists of solution tank, mixing box (with mixer), metering pumps, liquid level gauges, electric control cabinet, piping, valves, safety relief valves, check valves, pressure gauges, and the filters, base, escalators and other components. Dosing device according to the required reagent concentrations, in the mixing tank in the preparation, Blender mix evenly back into the solution box, use tricks to act as pumps (dosing pump) systems transport to dosage or specify the prepared solution. Complete set of dosing operations with compact structure, safe, simple, easy to use and so on.
