Abstract

Изобретение относитс к технике очистки газов от пыли и может быть применено в металлургической промышленности, преимущественно дл электросталеплавильных производств. Цель изобретени - сокращение выбросов, упрощение конструкции, повышение надежности, снижение стоимости очистки. Газопылевой поток отвод т от печи 2 по газопроводу 1 в камеру дожигани окиси углерода 3, откуда он поступает в газоочистной аппарат 4, а затем при помощи вентил тора 5 отводитс в дымовую трубу 6. Неорганизованные выбросы поступают в вентил ционное устройство 7, содержащее пылеконцентратор 8, где частицы пыли под действием центробежных сил отбрасываютс к стенкам корпуса, откуда поступают в улитку. Стру ми воздуха, истекающими из сопл сегнерова колеса, служащего и дл привода барабана и осевого вентил тора, пылевой концентрат из улитки выбрасываетс в трубопровод 10 и далее используетс дл дожигани окиси углерода в камере 3. Очищенный газ из пылеконцентратора 8 поступают в атмосферу. 1 з.п. ф-лы, 3 ил.The invention relates to a technique for cleaning gases from dust and can be applied in the metallurgical industry, mainly for electric steelmaking industries. The purpose of the invention is to reduce emissions, simplify the design, increase reliability, reduce cleaning costs. Gas and dust flow is diverted from furnace 2 via gas pipeline 1 to the afterburning chamber of carbon monoxide 3, from where it enters the gas cleaning unit 4, and then with the help of fan 5 is discharged into chimney 6. Unorganized emissions enter the ventilation unit 7 containing the concentrator 8 where the dust particles by the action of centrifugal forces are thrown against the walls of the body, from where they enter the cochlea. Air jets emanating from the nozzles of the Segner wheel serving both to drive the drum and axial fan, the dust concentrate from the cochlea is emitted into the pipe 10 and is then used to burn carbon monoxide in the chamber 3. The purified gas from the dust concentrator 8 enters the atmosphere. 1 hp f-ly, 3 ill.
