Embodiment 1

[0038] combine figure 1 , figure 2 As shown, the present embodiment provides an anti-water and dust accumulation sprinkler main pipe, including:

[0039] Ontology 1,

[0040] Anti-dust accumulation part 2, said anti-dust accumulation part 2 is fixedly installed on the top of said body 1, and said anti-dust accumulation part 2 is configured in an arc shape; and

[0041] The confluence part 3 is fixedly installed on the bottom of the main body 1, and the confluence part 3 is provided with sharp corners downward along the direction of gravity.

[0042] By setting the anti-deposition part 2 on the top of the body 1, and the anti-deposition part 2 is configured in an arc shape, it can effectively prevent dust from accumulating, and at the same time prevent the upper layer of slurry from directly dripping on the top of the body 1, reducing the impact of the slurry on the body 1. Corrosion on top.

[0043] By setting the confluence part 3 at the bottom of the body 1, and the con...

Embodiment 2

[0062] combine Figure 3-Figure 5 As shown, different from the above-mentioned embodiments, in the anti-water and dust accumulation sprinkler main pipe provided in this embodiment, the size of the side wing drainage part 4 along the length direction is smaller than the size of the body 1 along the length direction, and the The side wing drainage part 4 is arranged in the middle of the body 1 along the length direction.

[0063] On the main body 1 of the anti-accumulation and dust accumulation spraying main body 1, the side wing drainage part 4 is further arranged, and the side wing drainage part 4 is arranged under the outer surface of the body 1 with the largest diameter along the horizontal direction, on the one hand The slurry flowing down from the upper part of the main body 1 can flow away along the side wing drainage part 4, share the slurry collected by the confluence part 3, on the other hand, it can meet the structural strength and deformation requirements, and improv...

Abstract

The invention relates to the technical field of pipelines, in particular to a spraying main pipe capable of preventing water accumulation and dust accumulation. The spraying main pipe capable of preventing water accumulation and dust accumulation comprises a body and a dust accumulation preventing part, wherein the dust accumulation preventing part is fixedly installed at the top of the body, andthe dust accumulation preventing part is in an arc shape; and a confluence part which is fixedly installed at the bottom of the body, wherein the confluence part is downwards provided with a sharp corner in the gravity direction. According to the spraying main pipe capable of preventing water accumulation and dust accumulation, the dust accumulation preventing part is arranged at the top of the body, and the dust accumulation preventing part is arc-shaped so that dust accumulation can be effectively prevented; meanwhile, upper-layer slurry is prevented from directly dripping on the top of thebody, and corrosion of the slurry to the top of the body is reduced; and the confluence part is arranged at the bottom of the body, and the confluence part is downwards provided with the sharp cornerin the gravity direction so that slurry flowing down from the outer wall of the body can quickly slide away along the bottom of the confluence part, the retention time of the slurry on the outer wallof the body is shortened, and the corrosion of the slurry to the outer wall of the body can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a spray main pipe for preventing water and dust accumulation. Background technique [0002] As environmental protection is getting more and more attention all over the world, strict emission standards have been implemented for the emission of sulfur dioxide, one of the main pollutants in the atmosphere. In the iron and steel metallurgy industry and thermal power generation industry, due to the very high sulfur content of sintered ore in some areas, the sulfur dioxide content in the sintered flue gas can reach 5000mg / Nm3, and sometimes even reach 10000mg / Nm3 or more, far exceeding the emissions standard. However, at present, the newly-built one-million-unit units in thermal power plants are all required to meet the ultra-low emission standard. In order to make the sulfur dioxide content in the flue gas meet the emission standard, wet desulfurization is usually used, and the flu...
