A sludge receiving facility is provided with upper and lower structures respectively having inner spaces communicating with each other, wherein sludge tanks each having a sludge charging port are provided in the lower structure, and a partition wall configured to partition a carrying-in space of the upper structure from the inner space is provided, the sludge receiving facility including: outside air blowing means; air circulating means configured to enable the inner space and the carrying-in space to communicate with each other; first exhausting means configured to exhaust air from an upper part of the carrying-in space; second exhausting means configured to exhaust air above the sludge charging port; and third exhausting means configured to exhaust air inside the sludge tanks, wherein opening/closing means are respectively provided in the circulating means and the first to third exhausting means.

Ventilation system of sludge receiving facility

A wet sludge disposal facility is capable of smoothly transferring wet sludge to a kiln inlet part of a dry process kiln by a low feeding pressure and without substantially increasing the moisture content in the wet sludge. The disposal facility is used in a cement clinker manufacturing facility having a preheater for preheating a cement raw material, and a dry process kiln connected to the preheater at the kiln inlet part of the dry process kiln. Wet sludge is transferred to the side of the kiln inlet part by feeding water between the wet sludge and the inner wall surface of the pipe by a water injection apparatus in at least one place between the pressure feed pump and the kiln inlet part.
