Abstract
The invention relates to a method and apparatus for preventing dust accumulation of a flue gas inlet duct of an adsorption tower. Spray headers are arranged at a horizontal pipe part which is slantingly towards a bent pipeline outside an elbow of the bent pipeline connected with a flue entrance of a wet desulphurization tower, is led into the flue entrance of the wet desulphurization tower and is slantingly towards the flue entrance of the wet desulphurization tower in a slightly downward mode. The spray headers are utilized to regularly jet high-pressure washing water to positions inside the horizontal pipe part, where dust is accumulated, so as to wash the dust accumulated in the horizontal pipe into the wet desulphurization tower. Compared with the prior art, the method and the apparatus have the advantages of prevention accumulation of the dust at the flue entrance of the adsorption tower, simple structure and high reliability.
Description
Technical field:
The present invention relates to a kind of flue dedusting technology.
Background technology:
As shown in Figure 2, structure by wet desulphurization tower flue entrance is determined, 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 in flue that the dust accumulation whole flue weight that gets more and more is 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:
The goal of the invention of the present invention be in that 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。
The present inventionFor preventing adsorption tower smoke gas approach dust accumulation methodIt is realized in, cross tube sections at the slightly down 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, utilize the timing of this spray header to the position injection high-pressure washing water of sedimentating dust inside cross tube sections, the dust being deposited in transverse tube is washed away in entrance wet desulphurization tower.It is required for spraying into absorption liquid carries out flue gas desulfurization owing to flue gas enters in wet desulphurization tower, such that make the mud being entrained with dust enter in wet desulphurization tower, without the normal operation affecting wet desulphurization tower.
The present inventionFor preventing from adsorption tower smoke gas approach dust accumulation device to be achieved in that including with vertical tube andSlightly down being connected to of the transverse tube of sidelong wet desulphurization tower flue entranceAdsorption tower smoke porchBending pipeline, it is particular in thatCross tube sections at the slightly down 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.
The present invention 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 the structural representation of the present invention；
Fig. 2 is the schematic diagram of dust accumulation.
Detailed description of the invention:
In conjunction with drawings and Examples, the present invention is described in further detail:
As it is shown in figure 1, the present inventionFor preventing from adsorption tower smoke gas approach dust accumulation device to be achieved in that including with vertical tube 1a andSlightly down being connected to of the transverse tube 1b of sidelong wet desulphurization tower flue entranceAdsorption tower smoke porchBending pipeline1, it is particular in thatThe cross tube sections 1b of slightly down 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 sequentially arranged in front and back, 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 adopts Stainless steel 316 L material wear-resistant, corrosion resistant, and the material rinsing base is Q235A, outside brushing glass flake anticorrosion.
The present inventionFor preventing adsorption tower smoke gas approach dust accumulation methodIt is achieved in that and utilizes the timing of this spray header 2 to the position injection high-pressure washing water of sedimentating dust inside cross tube sections 1b, the dust being deposited in transverse tube 1b is washed away in entrance wet desulphurization tower.
