Description

Flat demister

Technical field:

The utility model relates to a kind of demister, especially relates to a kind of flat demister, is installed in the fume desulfurizing tower, is used for the flue gas desulfurization in power plant.Belong to the defogging equipment technical field.

Background technology:

Before the utility model was made, each power plant went out in the flue gas of chimney to have a large amount of harmful substances at present, and as sulfur dioxide, this part harmful substance is through handling and directly not being disposed in the atmosphere contaminated environment.For this reason, often adopt the limewash sulfur removal technology to remove harmful substances such as sulfur in smoke, still, flue gas goes out to have a large amount of water smoke when limewash is discharged, and this part water smoke needs to handle with demister.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can remove the moisture in the flue gas and discharge the flat demister of clean dried flue gas.

The purpose of this utility model is achieved in that a kind of flat demister, it is characterized in that it comprises upper strata demister, lower floor's demister, flushing water pipeline and nozzle,

Described upper strata demister is tabular, comprises upper strata demist sheet and upper strata gusset, and the upper strata gusset has multi-disc, and to being arranged by longitudinal separation, upper strata demist sheet has multi-disc from a left side, in the A-P lateral separation is placed through the upper strata gusset that longitudinal separation arranges; Spacing between the adjacent upper strata demist sheet is 25 ± 2mm;

Described lower floor demister is tabular, comprise lower floor's demist sheet and lower floor's muscle, lower floor's gusset has multi-disc, extremely arrange from a left side by longitudinal separation, lower floor's demist sheet has multi-disc, in the A-P lateral separation was placed through lower floor's gusset that longitudinal separation arranges, the spacing between the adjacent lower floor demist sheet was 40 ± 2mm;

Described upper strata demister and lower floor's demister are held on respectively on the interior upper and lower layer longeron of desulfurizing tower tower body,

Described flushing water pipeline has upper and lower two rows, on arrange flushing pipe and be hung in the desulfurizing tower on the longeron of upper strata, following row's flushing pipe is hung on the interior lower floor of the desulfurizing tower longeron,

Described nozzle has upper, middle and lower-ranking, and upper strata nozzle and middle level nozzle be the above and below of the row's of being arranged in flushing pipe respectively, is connected with last row's flushing pipe; Lower floor's arrangement of nozzles is connected with following row's flushing pipe in the top of arranging flushing pipe down.

The utility model can be removed the moisture in the flue gas and discharge the clean dried flue gas, and simple and compact for structure, and the pressure loss was little when flue gas passed through, demist efficient height, and installation takes up room little.
