Embodiment 2
[0078] Example 2 Treatment of wet sludge 300 tons / day
[0079] 300 tons / day of municipal sludge in a certain town is centrally disposed, and the system is equipped with 3 sets of treatment devices. The moisture content of the wet sludge is 80-85%. It is transported to the centralized sludge disposal plant by vehicle, and temporarily stored in the sludge silo. The carriage in the sludge silo reciprocates to squeeze the sludge into the sludge delivery pump. , transported to the disc-type drying equipment through pressure pipes, and the cutting sludge is stirred by the inner feathers and scrapers of the drying equipment, and after staying for 1-2 hours, it is dried into dry sludge with a moisture content of 35-40%. The diameter of mud particles is 3-5mm, which is transported to incineration or other final disposal through conveying equipment. The tail gas produced by drying contains a small amount of dust. The dust is regularly removed in the bag filter and electric heating is u...
Embodiment 3
[0080] Example 3 Treatment of wet sludge 200 tons / day
[0081] Centralized disposal of 200 tons / day of municipal sludge in a certain town is carried out in a waste incineration power plant. The low-quality steam in the power plant is used to dry the sludge, and the system is equipped with 2 sets of treatment devices. The moisture content of the wet sludge is 80-85%. It is transported to the garbage power plant by vehicle and stored temporarily in the sludge silo. The carriage in the sludge silo reciprocates to squeeze the sludge into the sludge delivery pump. The pressure pipeline is used to transport the sludge to the disc drying equipment, and the cutting sludge is stirred by the inner feathers and the mud cutter of the drying equipment. After staying for 1-2 hours, it is dried into dry sludge with a moisture content of 35-40%. The diameter of mud particles is 3-5mm, which is transported to incineration or other final disposal through conveying equipment. The tail gas prod...
