Title: Method of separating solid and liquid
Inventor: DEIITERU DEITSUSERUBETSUKU
IPC: B01D37/02
Filed: 1980-06-04
Abstract: The invention relates to a process for separating solids from liquid matter by means of gravity, using a three-dimensional filter element and an alluvial filter layer wherein a gas is fed into the medium to be treated prior to its introduction into the filter element in the form of fine or finest bubbles which accumulate on the solid particles. The particles loaded with air floated up rapidly to the upper level of the column of liquid in the filter element, forming a layer of sludge. Said layer built up continuously an alluvial filter layer at the internal surface of the water-permeable supporting filter element from the bottom upwards along the wall relative to the rising level of the liquid in the filter element. The process, realized in the presence or absence of flocculating agents, results in a higher separation degree with regard to the solids content as well as an increased elimination of the biological oxygen demand.

CONSTITUTION:In heating a strip 2 in a direct firing non-oxidative furnace comprising plural stages, the strip 2 is directly heated by a baking gas containing a non-combustion component and a minute amount of free oxygen generated by combustion due to a burner 4 in an air ratio of 1 or less. After the strip 2 is preheated by the high temp. exhaust gas from a heating furnace, it is heated by direct fire of a weakly oxidative combustion gas in the heating zone equipped with the burner 4. At this time, a gas permeable solid 7 comprising a foamed metal, a sintered metal or porous ceramics is arranged at right angles or a certain angle with respect to the advancing direction of the strip 2 and the combustion exhaust gas is passed through the gas permeable solid 7 to convert the heat contained in the exhaust gas to solid radiant heat. As the result, the strip can be heated in excellent heat efficiency and a heating apparatus itself can be also miniaturized.
