Description

Technical Field

[0002] In modern thermal power production, boilers are core equipment, and their long-term stable operation and efficiency are directly related to the economy and safety of the entire power generation system. Boiler water quality management is a key link to ensure this goal, among which the technology of adding chemicals to adjust water quality in the boiler is particularly important. This technology is based on the precise control of the chemical composition of boiler feed water and circulating water. It optimizes water quality by adding specific chemicals to the boiler to prevent scaling, corrosion and salt accumulation, and ensure steam quality. The traditional method of adding chemicals usually involves adding each chemical calculated in proportion to a mixing container at one time, mixing them through a stirring device, and then transporting the mixed liquid to the boiler system.

[0003] Although the above method ensures the basic dosage of the agent, it has problems in the following aspects: (1) Mixing uniformity: Direct stirring after a large amount of material is added at a time may not ensure sufficient contact and uniform distribution between all drug molecules.
