Raw water pretreatment and circulating water dosing device

The entire hydrazine dosing device consists of a solution tank, mixer, metering pump, electrical control cabinet, valves, pipelines, etc. It can be manually or automatically controlled on site. Automatic control is based on the frequency conversion device receiving signals from the hydrazine meter or oxygen meter. Function introduction of automatic control system: In automatic control mode, the system automatically adjusts the speed of the metering pump based on the signal from the hydrazine meter or oxygen meter, processed by PLC, upper computer or DCS. The flow rate adjustment range of the metering pump is 0-100%. The speed control input signal of the frequency converter is a standard 4-20mA signal, and the feedback signal is also a 4-20mA signal.

Instructions

The whole set of dosing device is composed of solution box, mixer, metering pump, electric control cabinet, valve, pipeline, etc. It can be controlled manually or automatically. The automatic control is based on the frequency receiving device receiving flow PH, conductivity and residual chlorine analysis. The signal from the instrument and the turbidity meter is realized. Function introduction of automatic control system: In the automatic control state, the system automatically adjusts the speed of the metering pump according to the flow, PH, conductivity, residual chlorine analyzer, turbidity meter signal through PLC, host computer or DCS, metering pump flow adjustment The range is 0~100%. The inverter's speed control input signal is a standard 4-20mA signal, and the feedback signal is also a 4-20mA signal. The status and fault signals of all metering pumps and mixers can be transmitted to the DCS or the host computer as needed. The DCS or the host computer can remotely start and stop the metering pump as needed.

The over-current material can be made of 316 stainless steel, 304 stainless steel, carbon steel, carbon steel lining (plastic), PE, PVC, etc. according to different corrosion resistance requirements.
