Embodiment Construction

[0023] Take the 1#9200 dedusting equipment of Laiwu Steel Ironmaking Plant as an example, the total pressure of the dedusting fan: 4200Pa, and the processing air volume: 670000 m 4 / h, the diameter of the dust collection pipe is 1000 mm. According to the structure figure 1 Shown:

[0024] Firstly, the steel pipe material with a wall thickness of 5 mm and a diameter of 1000 mm is used to make a purification dust collection pipe, and the outlet is connected to the dust collection pipe of the dust collector; the upper part of the purification dust collection pipe 1 is welded with a hook 3 at an appropriate position on the inner wall of the pipe, and the lower part of the outlet is inclined at 45° The lower hook 4 is welded on the inner wall of the pipe; the lower part of the pipe body is an arc-shaped plate-shaped cleaning door 5 with a length of 1000 mm and an arc width of 500 mm from the lower hook to the upper hook. Available airtight dust-removing cloth bag 6 covers parcel ...

Abstract

The invention discloses a novel oblique grid-type duct collecting pipe which mainly comprises a purification duct collecting pipe, movable oblique grids, a cleaning door, a cleaning cloth bag and a pipe wall vibrator and which can effectively prevent dust and impurities from entering the main body of a dust precipitator, wherein the purification duct collecting pipe has the shape of a conventional duct collecting pipe, upper hangers are welded on the inner wall of the upper part of the pipe body, lower hangers are welded on the inner wall of the lower part of the pipe body and inclined 45 degrees, the grids are connected through the upper and the lower hangers, the cleaning door is made of the same material as the purification duct collecting pipe and mounted by making an opening at the lower part of the body of the purification duct collecting pipe, a closed dust removal cloth bag is wrapped on the circumference of the opening of the door, the cleaning cloth bag is oppositely jointed with the closed dust removal cloth bag in the cleaning door, the pipe wall vibrator essentially consists of a vibrator and vibration transfer points, the vibrator is mounted on the outer wall of the upper part of the body of the purification duct collecting pipe, the vibration transfer points are attached to the upper hangers on the inner wall of the upper part of the body of the purification duct collecting pipe and close to an air inlet. The novel oblique grid-type duct collecting pipe has the advantages of simple structure, good decontamination effect and convenience in operation, and is widely applied to large-sized dust collecting pipelines working under harsh environments in various fields.

Description

technical field [0001] The invention relates to the technical field of large-scale dust removal pipelines in harsh environments such as mines and metallurgy, and belongs to the auxiliary facility technology of dust removal pipelines. Improve the dust removal efficiency and prolong the service life of the dust collector. Background technique [0002] In harsh environments such as mines and metallurgy, the working process of various large-scale dust collectors is "dust collection in the dust collection pipe → dust removal from the dust collector body → exhaustion of the purified air through the chimney and release of ash through the ash valve". Due to the harsh environmental conditions, the dust collected by the dust collection tube often contains various sundries (such as waste plastics, straw ropes, rags, etc.). It will interfere with the normal operation of the dust collector, seriously restrict the dust removal efficiency and shorten the service life of the dust collector...
