Method for drying, preferably the sewage sludge, and producing biofuel and organic fertilizers from them, and the device for the utilization of this method

摘要

the subject of the invention is a drying especially sewage sludge, manufacture of biofuels and organic fertilizers by heat treatment and device for application of this method.way is characterized by the fact that the granular termoodporny material completely separates from the dried sludge from urban waste water and again heading to heat in the heat exchanger, and the dried sludge is subjected zwu0119gleniu in reactor temperature above in order to obtain 300u00b0c her biowu0119gla.device for drying, particularly sewage sludge production of biofuels and organic fertilizers is characterized by the fact that the installation suszu0105cu0105 (1) constitutes a heat exchanger (2) for heating the heated hot termoodpornego granules, flue gases from furnace (3) for gasification smoke the lion standing, which is connected to the furnace (3) through the heating duct (15, 16).the heat exchanger (2) granules by reservoir (4) and feeder (8) is connected with the mieszalnikiem (6), which is mixed with wet sludge sewage hot termoodporny granules administered to the mixer (6) of the device (5), zasypowegoso prepared mixture after the initial evaporation and dropping pairs to the main heat exchanger (9) is supplied and dried with drying agent in a reactor (12), connected to the separator (14) for separating sludge from dry ingredients termoodpornego granules with an after power injector (13) part of the sludge is transported to the reactor (18) to zwu0119glania sludge and manufacture biowu0119gla,and the remaining part of the dry sludge is used in uzdatniaju0105cym device (19) for the production of organic fertilizers, and termoodporny granules are transported podajnikiem (20) to the tank zasypowego (21) heat exchanger (2) granules.
