Introduction
This device consists of a metering pump, a dosing tank, a mixer, a liquid level gauge, a scale inhibitor, a safety valve, a pressure gauge, and an electrical control cabinet (including a frequency converter). This system has the characteristics of reasonable design, high automation, safe and reliable operation, and simple operation. Widely used in water treatment and dosing systems for power plant feedwater, boiler water, raw water, circulating cooling water, and industrial wastewater and sewage. Pure water dosing includes: ① adding ammonia to feedwater and condensate; ② Adding hydrazine to water supply; ③ Add phosphate to the furnace. All of the above are for furnace dosing. Raw water and other additives include: ① adding coagulants and coagulant aids to raw water (raw water); ② Circulating water with stabilizer (corrosion inhibitor), scale inhibitor, and mixed bacterial agent; ③ The condenser is coated with ferrous sulfate, all of which are added outside the furnace. This series of dosing devices has been applied in dozens of various types of units and other enterprises in China, and has been highly praised by users.
HDJY-2001 is for pure water dosing, and HDJY-2002 is for external wastewater dosing. (Optional)
Characteristics
Realize 24-hour continuous control with a control accuracy of 0.5% -1%.
Can save more than 30% of medication usage.
Automatic monitoring and control, saving manpower.
The monitoring system can achieve networking.
Adopting computer control, the software design is flexible and can achieve various reports to meet the requirements of different users.
Advanced intelligent fuzzy regulation, output standard 4-20mA regulation signal and complete control unit composed of frequency converter.
Equipped with various control methods such as manual, automatic, and soft manual. Maximize the satisfaction of on-site requirements.
For different medicinal liquids, automatic dispensing and stirring can be achieved through a PLC system.
The solution tank, metering pump, system pipeline, and control system of the dosing device are centrally arranged to form a compact small unit structure, which is convenient for the design department's design and daily maintenance of users.
The solution tank, metering pump, and system pipeline prepared by the dosing device are all designed with anti-corrosion measures as needed. The main components in the control system are all products from internationally renowned companies.
The control system is equipped with functions such as electrical protection, low liquid level alarm, and automatic pump stop at low liquid level.
The data adopts Samsung's storage technology from South Korea, greatly increasing the amount of data. It can store tens of thousands of sets of measurement data and 5000 system operation records (known as the 5000 notepad function).
