VENTILATION SYSTEM OF SLUDGE RECEIVING FACILITY

摘要

A ventilation system of a sludge receiving facility capable of efficiently preventing gases such as odor from stagnating in a sludge tank and a structure covering the sludge tank by a small capacity ventilation means by selectively and carefully ventilating odorous places during normal operation and each time when sludge is received. In the sludge receiving facility, upper and lower structures (11, 12) communicating with an internal space (19) are constructed, entrances (13) having opening/closing means (14) are formed in the wall part of the upper structure (12), sludge tanks (15a, 15b) having sludge charging ports (17) are installed in the lower structure (11), and partition walls (21) are formed to partition loading spaces (22) in the upper structure from the internal space (19). The sludge receiving facility comprises an outside air blowing means (30) continuously blowing the outside air from the bottom part of the lower structure to the internal space, air flowing means (33) allowing the internal space to communicate with the loading spaces, first discharging means (35) discharging the air from the upper parts of the loading spaces, second discharging means (36) discharging the air on the upper sides of the sludge charging ports, and third discharging means (37a, 37b) discharging the air inside the sludge tanks. Furthermore, opening/closing means (33, 40, 41, 42a, 42b) are installed in the flowing means and first to third discharging means.
