Method for sealing off upper fume hood for generating electricity by using sintering remaining heat

Abstract

This invention provides a sealing method for smoke hoods on a cooler used in generating electricity with sintered waste heat including: 1, installing at least three independent smoke hoods with chimneys above the radiation surface of the cooler, 2, covering flexible anti-high-temperature material for sealing among the hoods on the longitudinal direction, 3, installing block sheets made of the flexible anti-high temperature materials on the side walls of the hoods, the bottom of which contacts with the side wall of the cooler to form a flexible mobile sealing to seal the cooler with the hoods and reduce cold air entering into the gap between the cooler and the hoods.

Description

Technical field: [0001] The invention relates to a sealing method, in particular to a sealing method for an upper fume hood of a belt cooler for sintering waste heat power generation. Background technique: [0002] In the iron and steel industry, the cooling of sintered ore is carried out through the belt cooler. The cold air is blown into the cooling air hole at the bottom of the belt cooler to cool the sinter on the belt cooler. After the cold air blown in passes through the sinter, It turns into flue gas with a certain amount of heat, and the flue gas is collected through the hood above the cooling machine, and then discharged from the chimney. In the prior art, since the fume hood used is an integral iron fume hood, the heat of the flue gas will deform the fume hood, and the cooling machine is constantly moving, while the fume hood is still Therefore, there must be a gap between the two, and the deformation of the hood will increase the gap, and the increased gap betwee...

Problems solved by technology

In the prior art, since the fume hood used is an integral iron fume hood, the heat of the flue gas will deform the fume hood, and the cooling machine is constantly moving, while the fume hood is still Therefore, there must be a gap between the two, and the deformation of the hood will increase the gap, and the increased gap between the cooler and the hood will make it easier for cold air to enter the hood. And reduce the heat of the flue gas in the fume hood, so it is unfavorable to the effective utilization of the heat of the flue gas in the fume hood, which is the weak point of the prior art
