Description

Technical Field

[0001] This utility model relates to the field of circulating water tanks in power plants, and in particular to an acid addition device for circulating water tanks in power plants. Background Technology

[0002] The circulating water in a power plant has certain requirements for its pH level. During the power plant's production process, the pH level of the circulating water in the circulating water tank is prone to change, requiring pH adjustment, which necessitates the use of an acid-adding device.

[0003] Existing sulfuric acid addition devices typically connect the sulfuric acid inside the sulfuric acid storage tank to a pipe that extends to the edge of a water tank, and then add the sulfuric acid to the edge of the circulating water tank to achieve the acid addition operation.

[0004] However, this method often results in the sulfuric acid entering the edge of the circulating water tank being too concentrated to be diluted in time, which can easily corrode the tank walls, thus presenting certain limitations. Utility Model Content
