Изобретение относитс к области газоочистки и может быть использовано при сухой очистке отход щих газов из конвертеров , установок десульфурации чугуна и т. д.The invention relates to the field of gas cleaning and can be used in the dry cleaning of waste gases from converters, cast iron desulfurization plants, etc.
Известен снособ очистки отход щих от агрегатов газов на тканевых фильтрах, включающий перегородку с образованием фильтрующего вспомогательного сло и регенерацию фильтрующей поверхности нутем обратной продувки подогретым воздухом 1,.A known removal method for cleaning waste gases from aggregates on fabric filters includes a partition with the formation of a filtering auxiliary layer and regeneration of the filtering surface with a reverse blown-out blown by heated air 1 ,.
Недостатком известного способа вл етс то, что фильтры быстро выход т из стро в результате залипани фильтрующей ткани, так как при фильтрации влажных газов происходит .конденсаци вод ных паров.The disadvantage of the known method is that the filters quickly get out of order as a result of sticking of the filter cloth, because the filtration of wet gases causes the condensation of water vapor.
Цель изобретени - обеспечение надежности работы фильтра за счет сохранени вспомогательного фильтрующего сло нутем предотвращени конденсации влаги.The purpose of the invention is to ensure the reliability of the filter by preserving the auxiliary filter layer to prevent moisture condensation.
Это достигаетс тем, что в способе очистки отход щих от агрегатов газов на тканевых фильтрах, включающем периодическую подачу очищаемого газа на фильтрующую перегородку с образованием вспомогательного фильтрующего сло и регенерацию фильтрующей поверхности путем обратной продувки подогретым воздухом, в период This is achieved by the fact that in the method of cleaning gases from the aggregates on fabric filters, including the periodic supply of the gas to be purified to the filter septum with the formation of an auxiliary filter layer and the regeneration of the filter surface by back blowing with heated air
очисткой газов и регенерацией фильтрующей поверхности, подогретый продувочный воздух надает в направлении очищаемого потока. gas cleaning and regeneration of the filtering surface, heated purging air is injected in the direction of the flow to be cleaned.
Схема осуществлени предлагаемого способа показана на чертеже.The scheme of the proposed method is shown in the drawing.
Схема включает установку десульфурацип чугуна 1, над которым расположено газозаборное устройство 2, соедин емое газопроводом гр зного газа 3, клапан 4 со всасывающим коллектором 5 тканевого фильтра 6. Входной коллектор 7 тканевого фильтра 6 газопроводом чистого газа 8 соединен с т годутьевым устройством 9. Система регенерации обратной продувкой состоит из вентустановки с калорифером 10, соединенной воздуховодом 11 через клапан 12 с продувочным коллектором 13 тканевого фильтра 6, и воздуховода 14, соединенного через клапан 15 со всасывающим коллектором 5 тканевого фильтра 6.The scheme includes the installation of desulfurization of cast iron 1, above which is located a gas intake device 2 connected by a gas pipeline of hazardous gas 3, a valve 4 with a suction manifold 5 of a fabric filter 6. The inlet collector 7 of a fabric filter 6 is connected with a gas pipeline of a clean gas 8 to a device 9. regeneration of the reverse purge consists of a ventilation unit with a heater 10 connected by a duct 11 through a valve 12 to a purge manifold 13 of a fabric filter 6, and an air duct 14 connected through a valve 15 to a suction pipe 5 lecturer fabric filter 6.
