Ammonia Dosing Device

1. Product Introduction of Ammonia Dosing Device

he complete Ammonia dosing device comprises a solution tank, a metering pump, an electric control cabinet, a level gauge, a safety valve, a buffer, various valves, pipelines, etc. It can be controlled manually and automatically. The automatic control is realized on the basis that the frequency converter system receives the flow, PH value, electric conductivity, signals of residual chlorine analyzer and turbidity meter. Introduction to functions of the automatic control system: Under automatic control state, the system automatically adjusts the rotating speed and stroke of the metering pump according to the flow, PH value, electrical conductivity, signals residual chlorine analyzer and turbidity meter subjected to PLC, upper computer and DCS treatment, wherein the flow adjustment range of the metering pump is 0~100%, the rotating speed control input signals of the frequency convertor are standard 4~20mA signals and the feedback signals are also 4~20mA signals. All state and fault signals of the metering pump and the stirrer can be transmitted to the DCS or upper computer according to demands, and the DCS or upper computer can start or stop the metering pump according to demands.

Feed water, condensation water add ammonia dosing device
Principle of processing
The dissociative CO2 in water, will make the water appears acidic. Reaction is as follows:
CO2+H2O H++HCO3-
So that the H+ in the water will react with carbon steel or other metals occurs hydrogen depolarization corrosion, result in damages to the iron components. Reaction is as follows:
H++2e H2 Fe Fe2+2e
Especially in high temperature and unbuffered chemical desalting water, free CO2 will greatly promote steel corrosion, therefore such electrochemical reaction must be suppressed by adding ammonia to improve the PH value of water, this will help to efficiently inhibit the H+dissociation, in order to control metal corrosion.

Ammonia Dosing Device Process overview
The device mainly consists of chemical solution metering system, melting and distribution system, metering and dosing system, security system and control system five parts.
Ammonia has been drawn into the metering system by water ejector, then adding in proportion to the metering and distribution system to be stirred and dissolved with desalted water and condensation water, through metering and dosing system to the boiler feed water or condensation water. Dosing can be controlled by manual or automatic--follow up control can be achieved by collecting the output signals from the host system.
