Abstract

The utility model provides an in the dust erodees and gets into the wet desulfurization tower that be used for preventing that absorption tower flue gas entry flue dust from piling up device, the violently pipe part that wet desulfurization tower flue inlet in the leading -in wet desulfurization tower flue inlet that bent pipe said in the outside slant of the return bend of saying at the bent pipe who links to each other with wet desulfurization tower flue inlet slightly down slant sets up the spray header, utilizes this spray header regularly to spray high -pressure sparge water to the position that the dust is piled up to horizontal pipe part the inside, will pile up horizontal intraductal. Compared with the prior art, the utility model, have can prevent the dust accumulational absorption tower flue gas entrance, simple structure, advantage that the reliability is high.

Description

One is used for preventing adsorption tower smoke gas approach dust accumulation device

Technical field:

This utility model relates to a kind of flue dedusting technology.

Background technology:

As shown in Figure 2, determined by the structure of wet desulphurization tower flue entrance, carry the flue gas of a large amount of dust before bending pipeline 1 enters wet desulphurization tower, the lower floor of pipeline forms detention layer, and so, dust will be deposited in porch, prolongation over time, cause the whole flue weight that gets more and more of dust accumulation in flue more and more heavier, chemical reaction badly damaged flue occurs in accumulation horizon A, cause the flue can not the stoppage in transit of the smooth whole desulphurization system of unimpeded flue gas.

Summary of the invention:

Goal of the invention of the present utility model be to provide a kind of can prevent dust accumulationAdsorption tower smoke porch, simple in construction, reliability are high is used for preventing adsorption tower smoke gas approach dust accumulation method and device。

This utility modelFor Prevent adsorption tower smoke gas approach dust accumulation device be achieved in that include with vertical tube andBeing connected to of the transverse tube of the most sidelong wet desulphurization tower flue entranceAdsorption tower smoke porchBending pipeline, it is particular in thatCross tube sections at the most sidelong wet desulphurization tower flue entrance importing wet desulphurization tower flue entrance of the sidelong bending in the outside pipeline of the bend pipe bending pipeline being connected with wet desulphurization tower flue entrance arranges spray header.

This utility model compared with the prior art, due to be provided with spray header to pile up dust be rinsed, therefore, have can prevent dust accumulationAdsorption tower smoke porch, simple in construction, reliability highAdvantage.

Accompanying drawing illustrates:

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the schematic diagram of dust accumulation.

Detailed description of the invention:

In conjunction with drawings and Examples, this utility model is described in further detail:

As it is shown in figure 1, this utility modelFor Prevent adsorption tower smoke gas approach dust accumulation device be achieved in that include with vertical tube 1a andThe transverse tube 1b of the most sidelong wet desulphurization tower flue entrance is connected toAdsorption tower smoke porchBending pipeline1 , it is particular in thatThe cross tube sections 1b of the most sidelong wet desulphurization tower flue entrance importing wet desulphurization tower flue entrance of the sidelong bending in the outside pipeline 1 of the bend pipe 1c of the bending pipeline 1 being connected with wet desulphurization tower flue entrance arrange more than two pierce into the spray header 2 into bend pipe 1c.

The spray header 2 of more than two is in the most sequentially arranging, to increase the area of flush clean.

Spray header 2 is fixed on bend pipe 1c by base 3, and the material of spray header 2 uses Stainless steel 316 L material wear-resistant, corrosion resistant, and the material rinsing base is Q235A, outside brushing glass flake anticorrosion.

This utility modelFor Prevent adsorption tower smoke gas approach dust accumulation methodIt is achieved in that the position injection high-pressure washing water utilizing this spray header 2 timing sedimentating dust inside cross tube sections 1b, the dust being deposited in transverse tube 1b is washed away in entrance wet desulphurization tower.
