Product Overview

This automatic chemical dosing device, developed and manufactured for chemical dosing, is mainly used for boiler feed water, circulating water, hydrazine addition, phosphate treatment, etc., in power plants. It can also be used in the petroleum, chemical, and water supply industries. The unit-type combined dosing device mainly consists of a solution tank, metering pump, filter, safety valve, check valve, pressure gauge, buffer tank, level gauge, and control cabinet, all integrated and mounted on a base. Users only need to place the combined dosing device in the dosing room, connect the inlet and outlet, and connect the power supply to start operation. This factory-assembled device greatly reduces the workload of design and on-site construction, providing good assurance for the quality of the entire system and on-site commissioning.

Working Principle

The chemical dosing device uses a metering pump as the main dosing equipment. The solution tank, stirrer, level gauge, safety valve, check valve, pressure gauge, filter, buffer, piping, access door, base, ladder, automatic monitoring system, and electrical control system are assembled on a common platform according to the process flow to form a module, the so-called skid-mounted combined unit (referred to as "skid"). A fixed amount of chemical agent is placed in the stirring solution tank for stirring and dissolving. After complete dissolution, it is sent to the dosing point through a metering pump. The dosing amount can be freely adjusted to meet the needs of different dosing locations. The dosing device adopts a mechatronics structure and can be divided into fixed and mobile (trolley) types in terms of installation. Each type of dosing device is equipped with a stirring system, a dosing system, and an automatic control system. Several fixed skids can be combined into a whole, and with a variable frequency control system, on-site control, remote automatic control, and manual and automatic switching dosing can be realized. The dosing device has the advantages of compact structure, small size, low noise, stable operation, simple installation, and convenient operation.

Through different process designs, the dosing device accurately configures solutions of various solid and liquid chemicals and then uses a metering pump for accurate dosing to achieve various design requirements. Dosing processes such as descaling, deoxygenation, coagulation, acid addition, and alkali addition can be manually operated or automatically controlled through a PC, magnetic level gauge, PH meter, stroke controller, and variable frequency drive, making the dosing device a mechatronics product.
