Movable slag hot-stew dust removal device and method

Abstract

The invention relates to a movable slag hot-stew dust removal device and method. In the slag hot-stew treatment process, in the operations of deslagging, drossing and slag-out, top-suction exhaust isconducted on hot-stew smoke in a plant through a movable hood vehicle. The movable hood vehicle is combined with a rotating cover for dust removal, the movable hood vehicle can move on a movable trackin a reciprocating manner for dust removal without influencing the slag hot-stew operation under the condition of opening the rotating cover; and the movable hood vehicle is connected with a telescopic pipeline, and the smoke enters a wet type hydrocyclone through the pipeline, is subjected to dust removal and then is exhausted from a chimney under the effect of a fan. The movable slag hot-stew dust removal device and method have the beneficial effects that based on the device and method, up-to-standard emission of hot-stew dust removal of the slag is achieved, PLC remote control is adopted for the device, the occupied area is small, the degree of automation is high, and the production operation is convenient. By the adoption of the movable slag hot-stew dust removal device and method, the production operation environment of workers in the slag hot-stew process is improved, the exhaust dust concentration of the dust removal smoke is lower than 30 mg / m<3>, and the organized up-to-standard emission of the smoke in the slag hot-stew plant is achieved.

Description

Technical field [0001] The invention relates to a mobile steel slag hot stuffiness dust removal device and method, in particular to a dust removal device and method in the steel slag hot stuffiness production process of iron and steel enterprises. Background technique [0002] my country is a major steel producer. In 2016, my country's steel output was about 800 million tons, accounting for more than half of the world's total. The production of one ton of steel per ton produces about 130kg of steel slag, and the annual output of steel slag in my country is more than 100 million tons. Steel slag is a solid waste generated in the steelmaking process. The treatment process of steel slag often produces flue gas containing a large amount of water vapor, which requires safe and environmentally friendly treatment. [0003] The steel slag hot stuffing process is suitable for the treatment of various types and shapes of steel slag. After the hot stuffing treatment, the steel slag, slag and...

AI Technical Summary

Problems solved by technology

Some domestic enterprises use side suction to remove dust on hot stuffy covers, but the dust removal power generated by side suction is small, and the dust removal effect is not obvious

If the roof dust removal method is used for treatment, the required air volume is large and the treatment cost is too high
