System for evaluating liquid foaming performance

Abstract

The invention discloses a system for evaluating a liquid foaming performance. The system includes a device for evaluating the liquid foaming performance. The device for evaluating the liquid foaming performance includes a transparent first cylinder body (2) of which a bottom end is sealed. A filter plate (6) is sealedly connected inside the first cylinder body (2). The interior of the first cylinder body (2) is divided into an upper hollow chamber (21) and a lower hollow chamber (22) in a vertically arranging manner. A gas inlet (7) is arranged on the bottom of the first cylinder body (2). The system also includes a gas source by which the lower hollow chamber (22) is filled with a gas. By means of the system, a foaming performance of a slurry sample in a desulfuration operation absorption column can be effectively researched. The system can guide an enterprise for adjusting an operation mode of the desulfuration operation absorption column so that various production safety problems caused by foaming in slurry are avoided.

Description

technical field [0001] The present invention relates to a system for evaluating the foaming properties of liquids. Background technique [0002] Limestone-wet flue gas desulfurization has the advantages of mature technology, wide adaptability, high desulfurization efficiency, and stable operation. It is currently widely used in coal-fired machines in my country. According to statistics, more than 85% of the thermal power coal-fired units with a capacity of more than 300MW in the country are limestone-wet flue gas desulfurization processes. However, due to insufficient initial design, deterioration of actual coal quality, equipment defects, lack of operating experience, and lack of in-depth optimization work, there are many problems in the operation of desulfurization facilities, which affect the The safe, stable and effective operation of the system. Foaming of the absorption tower slurry is one of the most common problems in the desulfurization operation of power plants a...
