Emission reduction device for unorganized emission at tail of sintering machine

Abstract

The invention discloses an emission reduction device for unorganized emission at the tail of a sintering machine, and belongs to the technical field of sintering and pelletizing environmental governance in the iron and steel industry. The emission reduction device comprises a tail star wheel moving frame, a sintering machine framework, a trolley, a tail star wheel, an air curtain machine, dust falling communicating pipes, chutes, an electric control valve and the like. The trolley is placed on the sintering machine framework, and the tail star wheel moving frame is installed on the sintering machine framework. The tail star wheel is installed in the tail star wheel moving frame, a material guide box is installed between the tail star wheel and a single-tooth-roller crusher, and the dust falling communicating pipes are installed at the two sides of the chute at the front end; flue gas generated in the falling and crushing process of sintered cakes is collected by a top dust collection cover and enters a tail dust remover; and small-particle materials scattered at the lower part of the tail star wheel are sealed by the air curtain machine, are collected by the dust falling communicating pipes of the chute at the rear end and then are merged into a tail dust removal system. The emission reduction device has the advantage that the unorganized emission of the dust-containing flue gas at the tail of the sintering machine is reduced to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of environmental treatment of sintering pellets in the iron and steel industry, and in particular relates to an emission reduction device for fugitive emission at the tail of a sintering machine. Background technique [0002] In April 2019, five ministries and commissions including the Ministry of Ecology and Environment promulgated the "Opinions on Promoting the Implementation of Ultra-Low Emissions in the Iron and Steel Industry", which clarified that the limit of fugitive emission of particulate matter from the tail of the sintering machine is 10mg / m 3 . [0003] The unloading material at the tail of the sintering machine is composed of two parts. Most of the sintered cakes are turned over by the trolley, broken by the single-toothed roller crusher and enter the front chute, and the chute (the rear chute) directly below the star wheel at the tail of the machine is collected as bulk material. Mainly, ther...
