Abstract
Description
technical field
[0001] The invention relates to a fully automatic on-line liquid density measuring device, in particular to a weighing device isolated from the system during density measurement. Background technique
[0002] During the operation of flue gas desulfurization process in power plants, the slurry density in the desulfurization reaction tower is a key parameter in the whole desulfurization process. When the slurry density in the desulfurization tower exceeds the limit value, measures should be taken immediately to replace the slurry in the tower to eliminate some high-density Slurry, add some fresh desulfurization original slurry.
[0003] At present, there are two online slurry density measurement methods used in the flue gas desulfurization process of coal-fired boilers.
[0004] One method is: double differential pressure liquid level measurement method, that is, install two double-flange differential pressure transmitters on the side wall of the desulfurizati...
