Smoke gas collecting hood

Abstract

The invention relates to the technical field of a circular cooler, and in particular relates to a smoke gas collecting hood. According to the key points of the technical scheme, the smoke gas collecting hood is arranged at the top of the circular cooler, and heat preservation cotton is paved the outer wall of the smoke gas collecting hood; a plurality of angle steels are horizontally arranged on the two opposite inner walls of the smoke gas collecting hood, and the angle steels are crisscrossed; and a baffling component is arranged at the top of the heat preservation cotton for keeping out ring or dust. The smoke gas collecting hood has the advantages of simple structure, easiness in assembly, high strength, no material accumulation and low manufacturing cost.

Description

technical field [0001] The present invention relates to the technical field of a collection hood, more specifically, it relates to a smoke collection hood. Background technique [0002] The ring cooler is composed of bellows, trolley and discharge chute. [0003] Annular coolers are widely used in the lump ore process of iron and steel, non-ferrous smelting, mineral processing and other enterprises. In order to effectively utilize the thermal energy of the minerals on the annular cooler, a high-temperature flue gas collection cover is usually installed on the upper part of the annular cooler to collect high-temperature flue gas for power generation. The traditional fume collection hood is a box with a rectangular cross section. The side of the fume collection hood is above the fence of the ring cooler. The upper cover of the fume collection hood is a horizontal steel plate. 100-150mm thick thermal insulation cotton is installed on the outer surface. [0004] There are def...

AI Technical Summary

Problems solved by technology

[0004] There are defects in the above-mentioned technical scheme: 1. Since the flue gas collection hood is often in the state of alternating cold and heat, the steel plate of the flue gas collection hood is easily deformed, and the gap between the bottom of the flue gas collection hood and the upper edge of the slab of the ring cooler increases. Large, resulting in heat loss and low power generation;

[0005] 2. Due to the horizontal arrangement of the flat steel plate on the upper part of the flue gas collection hood, the area of ​​the annular cooler is in a dusty area, and the dust accumulation on the flat steel plate on the upper part of the flue gas collection hood is serious. The serious dust accumulation increases the force of the flue gas collection hood, resulting in smoke The deformation of the gas collection cover is more serious
