Wet desulphurization accident slurry system

Abstract

The invention relates to a wet desulphurization accident slurry system, which comprises an accident slurry recovery assembly, an absorption tower assembly, a drainage pit assembly, a gypsum slurry box and a mother pipe, the accident slurry recovery assembly comprises the accident slurry box and an outlet pump set, and a liquid inlet of the accident slurry box is communicated with a liquid outlet of the gypsum slurry box and the mother pipe through pipelines. A liquid outlet of the accident slurry box is connected with the main pipe through an outlet pump set, the absorption tower assembly comprises at least one absorption tower and a gypsum discharge pump set, a gypsum discharge port of the absorption tower is communicated with a liquid inlet of the gypsum slurry box through the gypsum discharge pump set and a valve, and a liquid outlet pipeline of the gypsum discharge pump set is further communicated with the main pipe through a valve. A first liquid inlet of the absorption tower is communicated with the main pipe through a valve, and a liquid outlet of the drainage pit assembly is respectively communicated with the main pipe and a second liquid inlet of the absorption tower through valves. Compared with the prior art, the system has the advantages of effectively recovering the accident slurry of the desulfurization system, improving the system stability, reducing the water consumption and the like.

Description

technical field [0001] The invention relates to the field of wet desulfurization, in particular to a wet desulfurization accident slurry system. Background technique [0002] The wet desulfurization system needs to design the slurry discharge system, that is, the accident slurry system. The accident slurry discharge system is an important system to ensure the stable operation of the desulfurization facilities. Its main function is to discharge the slurry in the system to the accident slurry tank when the desulfurization system fails, so as to empty the absorption tower or the system (in the drainage pit) in time. ) of the slurry. [0003] The accident slurry tank in the prior art can only collect and temporarily store the slurry in the absorption tower and drainage pit under fault conditions, and the slurry cannot be effectively re-injected into the absorption tower and drainage pit for reuse, and the water recycling rate is low, resulting in Slurry waste under fault condi...
