Abstract

The invention discloses a converter dry dedusting and waste heat recycling device and method. The device comprises a smoke gas ingredient concentration intervention section component, a high-temperature smoke gas cooling section component, a gravity dedusting component, a cloth bag dust remover, a low-temperature smoke gas cooling section component and a mixer. An evaporative cooling flue outlet of a converter smoke outlet is sequentially connected with the smoke gas ingredient concentration intervention section component and the high-temperature smoke gas cooling section component and then isconnected with an inlet of the gravity dust removal component, an outlet of the gravity dust removal component is connected with an inlet of the cloth bag dust remover, an outlet of the cloth bag dust remover is connected with an inlet of the low-temperature smoke gas cooling section component through a pipeline, and an outlet of the low-temperature smoke gas cooling section component is connected with a smoke gas recycling mechanism. Smoke gas produced in a converter can be quite effectively purified, the temperature of smoke gas entering a cloth bag for dust removal can be controlled withina certain range, smoke gas waste heat can be absorbed, and the low-temperature waste heat recycling problem is solved.

Description

technical field [0001] The invention belongs to the field of converter steelmaking dedusting in the metallurgical industry, and in particular relates to a converter dry dedusting and waste heat recovery device and method. Background technique [0002] With the progress of the industrial economy and human civilization, environmental protection issues and industrial production energy conservation have attracted more and more attention. The full recovery and utilization of industrial waste heat and energy has surpassed pure economic considerations. The converter gas produced in the converter steelmaking process contains A large amount of heat has a high recovery value. At present, the method of purifying and dedusting converter gas is mainly wet dedusting, that is, the excessive water spraying cooling and dedusting system is directly used to reduce the dust content of the flue gas, but the emission cannot meet the standard. The essence of its explosion-proof is to eliminate the...
