Abstract
PURPOSE: To prevent the increase of pressure loss due to coagulation of dusts, by charging into the dust collector the granule or block type filter medium preheated by utilizing the sensible heat of the dust including waste gas like as (preheated) waste gas of the blast furnace, etc., and by passing the dust including waste gas through this dust collector for preventing the moisture condensation in the waste gas within the dust collector.
CONSTITUTION: The granule or block type filter medium 4 of small particle size is supplied at constant rate from the filter medium feeder 7 into the duct 2 for transporting the dust including waste gas (about 150°C) produced by the blast furncace 1, for preheating the filter medium 4 to temperatures above the dew point of the waste gas; and thus preheated filter medium 4 together with the waste gas are introduced into the cyclone 8. Next, the separated filter medium 4 is put into the dust collecting bed 6 of the dust collector 3, and the dust including waste gas from the cyclone 8 is introduced into the dust collector 3. The dust included in the waste gas adheres to surface of preheated filter medium 4 and also is retained in the space among particles of filter medium 4; hereby, the dust is collected. According to this method, the moisture condensation in waste gas and the coagulation of dusts on the surface of filter medium 4 do not occur so that the dust collection can be executed at low pressure loss and high performance.
