Dust hood and converter three-time dust removal system thereof

Abstract

The invention provides a dust hood and a converter three-time dust removal system thereof. The dust hood comprises two side sealing plates, a top plate and a dust removal pipeline, wherein the two side sealing plates are the same in structure and are arranged in parallel at an interval; the upper end surface of each side sealing plate is an arc surface; the top plate covers the two side sealing plates; the longitudinal section of the top plate is arc-shaped; the inner arc surface of the top plate is fixedly connected with the upper end surfaces of the two side sealing plates; the top plate andthe two side sealing plates jointly define a dust removal space with an opening in the lower end; and the dust removal pipeline is arranged on the outer arc surface of the top plate and communicateswith the dust removal space. The dust hood has the beneficial effects that the top plate with an arc plate-shaped structure is arranged, so that the buffering effect of rising smoke dust can be improved, the possibility that the smoke dust is diffused all around is reduced, and the retention time of the smoke dust in the dust hood is prolonged; and therefore, the smoke dust can be fully sucked away by the dust removal pipeline, and the aim of improving the dust removal effect is fulfilled.

Description

technical field [0001] The invention relates to the technical field of dust removal, in particular to a dust removal cover and a tertiary dust removal system for a converter. Background technique [0002] For the third dust removal of the converter, a dust collection hood is added on the roof above the converter to collect dust, and then the dust removal pipeline is connected. Under the negative pressure of the fan, the smoke is drawn to the pulse bag filter for filtration and purification. [0003] The important parameter of the dust removal fan is the dust removal air volume. The determination of the air volume of the tertiary dust removal system of the converter is mostly based on the high suspension hood theory, through the distance from the imaginary point heat source to the heat source surface, the distance from the heat source surface to the hood opening, the diameter of the smelting tank, the temperature of the smelting metal, and the environment. Temperature, smoke ...

AI Technical Summary

Problems solved by technology

The dust removal hoods in the prior art are all spliced ​​by straight steel plates. After encountering the straight steel plates, the rising smoke generated by the converter will quickly spread around because it cannot be effectively buffered, resulting in a larger area of ​​the collection hood; the lower part of the dust removal hood The collection port is large, the upper suction port is relatively small, and the steel plate around the dust cover body needs to strengthen the diversion effect of the smoke and dust
