This device mainly includes four parts: drug solution preparation system, metering and dosing system, safety system, and control system. Solid phosphate is added to the solution tank, then added to desalinated water or condensed water in proportion and stirred to dissolve. It is then added to the boiler drum through a metering system. The dosing control can be done manually or automatically based on the control signal output by the upper system.

In the process of water supply and sewage treatment, various chemical agents need to be added to achieve the treatment objectives. Therefore, advanced dosing systems and dissolution dosing equipment are important components of water treatment engineering. Water treatment projects are designed with chemical dissolution equipment, which uses mechanical stirring or compressed air stirring to quickly dissolve solid chemicals, and then add them to the water body through dosing and metering equipment. The addition of drugs usually does not have filtering equipment, and undissolved impurities are very detrimental to the dosing and metering equipment, and even cannot operate normally due to blockage. The entire dosing system is complex, occupies a large area, and has inaccurate dosing, resulting in poor economic operation and inconvenient operation and management of the treatment system, especially in small and medium-sized water treatment projects. Our factory refers to foreign dosing equipment and combines the processes of dissolving and dosing in the same equipment. We have added a chemical filtration facility and designed it as a ZJ type automatic dosing new equipment.

Combination dosing device is a new concept of chemical water treatment dosing technology, which has been widely used in water treatment fields such as power, chemical, municipal, etc. at home and abroad.

The two box three pump dosing device is a new concept of chemical water treatment dosing technology, which has been widely used in the fields of power, chemical, municipal and other water treatment at home and abroad. The two box three pump dosing device is a device that installs all equipment and components such as the metering pump, dissolution tank, control system, and pipeline valves on the same base platform, achieving the overall combination of dissolution and dosing functional units. Huaneng Power Auxiliary Equipment has accumulated years of technology and experience in water treatment. Based on the treatment requirements and dosing characteristics of different water qualities, it draws on and absorbs advanced dosing technologies at home and abroad, and provides high standard water treatment system solutions as its product design concept. It has developed and launched a new combination dosing device with advanced reliability, flexible configuration, and the ability to meet users' arbitrary choices.

AM dosing device is a critical process in water treatment. Widely used in domestic water supply, industrial water supply, domestic sewage treatment, industrial sewage treatment, papermaking wastewater, printing and dyeing textile wastewater, petrochemical wastewater treatment, electronic wastewater and other fields.

The fully automatic dosing device is mainly used for adjusting the pH value of boiler feedwater, maintaining the pH value of boiler feedwater within a certain range and operating in the optimal state, preventing the imbalance of boiler feedwater pH value and causing acid-base corrosion of boilers and other thermal equipment, enabling the thermal system to work in the optimal state, extending the service life of thermal equipment, and ensuring the long-term stable and safe operation of thermal equipment.
