Abstract

The invention provides a treatment system of a furnace top gas of a COREX vertical furnace. The treatment system comprises the COREX vertical furnace and a gravity dust remover connected with the COREX vertical furnace; the treatment system of the furnace top gas of the COREX vertical furnace further comprises a first atomization rapid cooling device arranged on the furnace top of the COREX vertical furnace, a second atomization rapid cooling device arranged inside the gravity dust remover, a cloth bag dust remover connected with the gravity dust remover, and a flow adjusting device connected with the cloth bag dust remover. The invention further provides a treatment method of the treatment system of the furnace top gas of the COREX vertical furnace. According to the treatment system of the furnace top gas of the COREX vertical furnace, disclosed by the invention, on the basis of common gas dry-method dust-removing treatment configuration, adjustable and controllable atomization rapid cooling equipment and control technology, and gas flow adjusting and controlling equipment and technology are combined to realize the accurate online control on temperatures, flows and pressure of the gas; the flow adjusting device is simple in equipment and convenient to operate, and all valves of a valve group have different adjusting ranges and precisions, so as to meet the requirements on adjusting a gas amount when a working condition of the vertical furnace is changed.

Description

technical field [0001] The invention relates to the industrial field of gas preparation or collection systems, in particular to a COREX shaft furnace top gas treatment system and a treatment method thereof. Background technique [0002] For the current gas treatment system in the metallurgical industry, such as blast furnace top gas dust removal and purification system, COREX shaft furnace top gas treatment system, there are generally two treatment processes: wet dust removal and dry dust removal. Wet dedusting is a mature process, but due to its backward process, a large amount of sewage needs to be treated, and complicated equipment, it tends to be replaced by dry dedusting process. Compared with the wet dedusting process, the dry dedusting process is characterized by no large amount of sewage treatment and a good environment, which is widely welcomed by industrial enterprises. [0003] The dry dedusting process is in the initial stage of development and application. The ...
