Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment, and more specifically, it is a gable type demister arranged independently. The utility model also relates to a flushing water system for such a gable type demister arranged independently. Background Art

[0002] The wet flue gas desulfurization technology is widely used in flue gas treatment due to its high desulfurization efficiency. However, the wet flue gas desulfurization technology also leads to an increase in the water content of the flue gas, and chimney rain is likely to occur during the external discharge, causing potential hazards such as pollution, corrosion on the surfaces of equipment and structures around the plant area, and icing on the road surface in winter. Therefore, when designing a desulfurization system, a demister of an appropriate type will be configured in the absorption tower to reduce the liquid carry - over amount of the flue gas.

[0003] When designing a demister, usually according to the requirements of the inlet flue gas droplet content and the outlet droplet content, a combination of demisters with various structures and the selection of different demister blade types and other schemes are adopted to ensure that droplets of different particle sizes can be efficiently and stably removed.

[0004] In the flue gas desulfurization tower of a coal - fired power plant, a three - stage gable type demister is often used. To reduce the installation height of the demister and the number of support beam layers of the demister, the most common arrangement form is "one - stage gable + diamond", but the existing "one - stage gable + diamond" arrangement form has the following problems:

[0005] 1) Multiple branches are provided in the flushing water pipeline. At the moment of starting flushing, the turning point of the flushing water pipeline bears a large pulse pressure. During long - term operation, the pipeline joints are extremely prone to leakage, affecting the flushing effect on the demister blades.

[0006] 2) The flushing water pipelines under the first and third demister layers are usually supported by PP - material strip plates. During long - term operation, affected by the flue gas temperature in the tower, the impact of the flushing water pipes, etc., the support strip plates are prone to deformation and bending, and then lose the support effect on the relevant flushing water pipelines.

[0007] 3) The demister and the flushing water pipeline are designed for integral assembly. When a part of the demister module collapses due to blockage and needs to be replaced, the surrounding associated flushing water pipelines need to be removed simultaneously, which is not convenient for maintenance work.

[0008] Therefore, it is very necessary to develop a gable type demister and its flushing water system that can operate stably, efficiently and for a long time and is convenient for maintenance. Summary of the Invention

[0052] The flushing water pipeline 8 further includes a tower wall side flushing water pipe 84 arranged on the sixth flushing water support 79.

[0053] Flushing nozzles 85 are arranged at intervals on the first-stage upper flushing water pipe 811, the first-stage lower flushing water pipe 812, the second-stage upper flushing water pipe 821, the second-stage lower flushing water pipe 822, the third-stage upper flushing water pipe 831, the third-stage lower flushing water pipe 832, and the tower wall side flushing water pipe 84.

[0054] In actual use, as Figure 1 shown, three-stage demisting layers are arranged in the absorption tower 1 of the present utility model, wherein the first-stage demisting layer 2 is arranged in a roof type, and the second-stage demisting layer 3 and the third-stage demisting layer 4 are arranged in a rhombus shape as a whole; each stage of demisting layer is bolted and spliced by a plurality of demister modules with regular shapes, the demister modules are densely arranged along the cross-section of the absorption tower 1, and demister sealing plates are adopted at the pore positions near the tower wall of the absorption tower 1 to ensure that the wet flue gas flows through the pores between the demister blades.

[0055] As Figure 2As shown in the figure, a first demister support structure 5 and a second demister support structure 6 are arranged inside the absorption tower 1. The first support plate 52 is arranged on both sides of the first support beam 51 as the installation plane of the first-stage demister module 21. The second back support plate 62 is arranged on both sides of the back of the second support beam 61 as the installation plane of the second-stage demister module 31. The second front support plate 63 is arranged on both sides of the front of the second support beam 61 as the installation plane of the third-stage demister module 41.

[0056] The first support frame 71 is connected to adjacent first support beams 51 to support the first-stage upper flushing water pipe 811. The second support frame 72 is connected to adjacent second support beams 61 to support the second-stage lower flushing water pipe 822 and the third-stage upper flushing water pipe 831. The back of the second support frame 72 serves as the rooting plane of the flushing water pipe hanger 76, realizing the independent arrangement of the demister module and the flushing water pipeline.

[0057] To prevent the demister blades from being blocked, each demister layer is equipped with upper and lower layers of flushing water pipes, that is, the first-stage upper flushing water pipe 811 and the first-stage lower flushing water pipe 812 correspond to the first-stage demister layer 2, the second-stage upper flushing water pipe 821 and the second-stage lower flushing water pipe 822 correspond to the second-stage demister layer 3, and the third-stage upper flushing water pipe 831 and the third-stage lower flushing water pipe 832 correspond to the third-stage demister layer 4.

[0058] As Figure 2 shown, for the flushing of the demister module near the tower wall side of the absorption tower 1, a separate tower wall side flushing water pipe 84 is set up, which is responsible for the lower flushing of the first-stage demister module 21 on the tower wall side and the upper flushing of the second-stage demister module 31. Since the scaling risk of the third-stage demister layer 4 is low in actual application and the flushing interval is the longest, a separate tower wall side flushing water pipe is no longer set for the third-stage demister module 31 on the tower wall side of the absorption tower 1.

[0059] As Figure 4 shown, the flushing water pipeline 8 is all arranged with straight pipes. The straight pipe arrangement can avoid the hidden danger of leakage caused by the pulse pressure borne by the turning point of the flushing water pipeline during the instant of starting flushing for long-term operation. In the central area of the absorption tower 1, each flushing water pipe is responsible for the flushing of the adjacent two-side demister modules.

[0060] The first-stage upper flushing water pipe 811, the first-stage lower flushing water pipe 812, the second-stage upper flushing water pipe 821, the second-stage lower flushing water pipe 822, the third-stage upper flushing water pipe 831, the third-stage lower flushing water pipe 832, and the tower wall side flushing water pipe 84 are all installed on their corresponding supports and hangers and fixed with pipe clamps.

[0061] The demister module is arranged independently of the flushing water pipeline, and the installation and replacement do not affect each other; moreover, the demister module is bolted to the demister support structure, avoiding the risk of the demister module tilting or collapsing.

[0062] Other parts not described belong to the prior art.
