A system and construction method for defoaming and density measurement of slurry outside a desulfurization absorption tower

Abstract

The invention discloses a defoaming and density measuring system and a construction method for slurry outside a desulfurization absorption tower. The defoaming pipeline on the slurry pipeline, the buffer device connected to the defoaming pipeline, the nozzle connected to the downstream end of the defoaming pipeline, the defoaming box connected under the nozzle, the discharge pipeline connected to the bottom of the defoaming box, the discharge pipeline connected to the discharge A density meter in the pipeline and a ditch connected under the discharge pipeline; the buffer device includes a connecting pipe and an orifice in the connecting pipe. During construction, the present invention can effectively eliminate bubbles through the joint arrangement of defoaming pipes, nozzles and defoaming boxes, save the time of defoaming and the size of the defoaming box, and increase the measurement efficiency and accuracy; through the setting of the buffer device , the slurry can be transported under reduced pressure; through the connection of the defoaming box and the discharge pipeline, it is easy for the slurry to flow freely and measure the density.

Description

technical field [0001] The invention belongs to the technical field of wet desulfurization engineering, and in particular relates to a defoaming and density measuring system and a construction method for slurry outside a desulfurization absorption tower. Background technique [0002] In the limestone-gypsum wet desulfurization process, it is necessary to control several parameters in the absorption tower. Among them, the slurry density is a direct control parameter to judge whether the absorption tower is in an accident state, and an indirect parameter to determine the liquid level in the absorption tower according to the pressure difference. Therefore, the slurry density is one of the most important parameters in the wet desulfurization process. [0003] In the past, the density measurement of the absorption tower adopts two methods of high and low pressure differential density measurement or measurement outside the sampling tower. In recent years, with the large-scale ex...
