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-deposition part 2, the anti-deposition part 2 is fixedly installed on the top of the body 1, and the anti-deposition part 2 is configured as a triangle; 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 as a triangle, 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 top of the body 1. of corrosion.

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

Embodiment 2

[0058] 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 confluence part 3 along the length direction is smaller than the size of the body 1 along the length direction, and is arranged at the The middle position of the main body 1 along the length direction.

[0059] Specifically, the anti-water and dust accumulation sprinkler main pipe also includes side wing drainage parts 4, and the side wing drainage parts 4 are arranged below the outer surface of the main body 1 where the diameter along the horizontal direction is the largest.

[0060] Specifically, the side wing drainage portion 4 extends from the end portion of the body 1 in the axial direction to the middle portion, and is inclined downward along the direction of gravity during the extension process.

[0061] Specifically, the side wing drainage portion 4 is at least partially ove...

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, the dust accumulation preventing part is fixedly installed at the top of the body, and the dustaccumulation preventing part is of a triangular structure; and the spraying main pipe capable of preventing water accumulation and dust accumulation also comprises a confluence part which is fixedlyinstalled at the bottom of the body, and the confluence part is downwards provided with a sharp corner in the gravity direction. The dust accumulation preventing part is arranged at the top of the body and is of a triangular structure, dust accumulation can be effectively prevented, meanwhile, upper-layer slurry is prevented from directly dripping to the top of the body, 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 corner in 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 wall of 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...
