Definitions
- the mixing ratio of the sludge, the dewatered sludge and the sludge drying carrier mixed by the stirring device in the step (2) is: 1 : 0.45 ⁇ 1: 3
- the sludge filter cake (the sludge after dewatering and dewatering) removed from the plate and frame filter press, with a water content of 65%, is conveyed to the stirring and mixing device by a screw conveyor, and has a water content of 1.4 as a dry carrier for the dewatered sludge. % dry
- the clay is mixed.
- the dry clay conveying speed is 14kg/min
- the dry-wet ratio is set to 1.15: 1
- the wet (after dewatering) sludge conveying speed is 12kg/min
- the mixed sludge discharged after mixing and mixing device has a water content of 31%.
- a part of the mixed sludge is continuously dried as a carrier for sludge drying; the other part is packaged as a finished product after drying, and the moisture content of the finished sludge after drying is 31%.
- the water content of the dewatered sludge to be dried in the step (1) described in the above method is 69 to 51%.
- the sludge drying carrier has a water content of 10 to 1% and a particle diameter of 0.25 to 1.0 mm.
- a part of the sludge with a moisture content of 1.8% after drying is sent to the dry silo to maintain the production level, and a part of the sludge is output to another stirring and mixing device, and the water content is 65.
- the % sludge filter cake is mixed to a moisture content of 45% and then output as a finished product.
