Description

пературы газа и содержани  твердого в пульпе. При отборе газа до теплоиспользуюишх установок необходимо 1/7-1/10 часть отход щих газов, при отборе после теплоиспользуюших установок - 1/51/6 . В токе гор чих дымовых газов вода пульпы испар етс , а тверда  составл юша  комкуетс .gas and solids in the pulp. When gas is taken up to heat utilization, 1 / 7-1 / 10 part of the exhaust gases is needed, while after gas extraction, it is 1/51/6. In a stream of hot flue gases, the water of the pulp evaporates, and the solid is compacted.

При использовании предложенного способа на мокрую очистку идет соответст венно меньше газсш и дл  их обработки требуетс  на 10-20% меньше воды. Цикл водоснабжени  дл  транспортировки улов ленной пыли искшочаетс , отпадает необходимость установки осветительного оборудрвани  (сгустители, отстойники, шла- монаконители) и высвобождаетс  техйи™ ческа  вода в среднем 0,5 л/м очищаемого газа. Пыль и шлам, окомкованные в гранулы, отправл ют в сталеплавильиый агрегат или на агломерацию.When using the proposed method, respectively, less gas is used for wet cleaning and 10-20% less water is required for their treatment. The water supply cycle for transporting the captured dust is disturbed, the need to install lighting equipment (thickeners, septic tanks, sludge drains) is eliminated, and technical water is released on average 0.5 l / m of gas to be purified. Dust and sludge pelletized into granules are sent to a steel-smelting unit or for agglomeration.

Пример .Полученные после мокр   сухой очистки мартеновских газов шла и пыль перемешивают, и пульпу при содержании твердого 500 г/л подают на установку сушки в гранул ции диаметром 10О мм. Сушку и псевдоожижение осуществл ют разбавлею1ыми воздухом про дуктами горени  природного газа с температурой 500°С, Полученные гранулы Example. After the dry gas cleaning of open-hearth gases obtained after wet, the dust was mixed and the pulp with a solid content of 500 g / l was fed to a drying unit in granulation with a diameter of 10 mm. Drying and fluidization are carried out with dilute air from the combustion products of natural gas with a temperature of 500 ° C. The resulting granules

размером 5-10 мм имеют прочность на раздавливание 8-10 кг, что достаточно дл  перевозки их внутризаводским транспортом . Унос истираемой пыли из аппарата сушки и гранул ции не превышает 3%. Газы очищают в рукавном фильтре.5-10 mm in size, they have a crush strength of 8-10 kg, which is sufficient for transportation by internal factory transport. The entrainment of abraded dust from the drying and granulation apparatus does not exceed 3%. Gases are cleaned in a bag filter.
