Device and method for carrying out dust removing treatment on dust-containing steam in steel slag treating and rolling zone

Abstract

The invention relates to a device and a method for carrying out dust removing treatment on dust-containing steam in a steel slag treating and rolling zone. The device comprises a spray tower, a rotational flow tower and a pipeline, wherein the pipeline is used for connecting the spray tower with the rotational flow tower; a first high-pressure spray gun is arranged at the upper part of the spray tower; a first opening is formed in the top part of the spray tower; the first opening is connected with a rolling space through a pipeline, and is used for guiding the dust-containing steam generated in a rolling zone into the top part of the spray tower; the pipeline which is used for connecting the spray tower with the rotational flow tower is arranged at the bottom parts of the spray tower and the rotational flow tower, and is used for guiding the dust-containing steam which is treated by the spray tower into the rotational flow tower along the tangential direction so as to enable the dust-containing steam for continuous flowing; a second high-pressure spray gun is arranged at the bottom part of the rotational flow tower; a rotational flow cone is arranged at the middle part of the rotational flow tower; a second opening is formed in the top part of the rotational flow tower, and is used for discharging the steam which is treated by the rotational flow tower. The device disclosed by the invention has the advantage that the dust removing efficiency and the device maintenance quantity are greatly reduced.

Description

technical field [0001] The invention is a new process for dedusting the dust-containing steam in the steel slag processing rolling area. The invention adopts two methods of spraying dust removal and swirl separation to continuously process the dust-containing steam to realize the dedusting of the dust-containing steam. Background technique [0002] In the steelmaking steel slag autoclaving process, the dust-containing steam generated during the rolling process of steel slag has high dust concentration, small dust particle size, and difficult dust removal. After the flue gas is dedusted, the collected dust can be recycled back to the steel slag processing line, which not only protects the environment, but also avoids energy waste. At present, there are relatively few dust removal methods for this area in China, and most of them use dirt-folding plate dust collectors. The principle of the dirt-folding plate dust collector is: by setting the dirt-folding plate, the probability...
