Title:
汚泥乾燥方法および汚泥乾燥設備
Document Type and Number:
Japanese Patent JP2013534180
Kind Code:
A
Abstract:
This sludge drying device is characterised in that a gas entraining a mix of sludge and sand is recycled after drying (6) and separation (8) to be compressed (10) and circulate again through the dryer (6) acting as a heat exchange fluid. Compression has been performed to increase the dew point temperature of the gas containing the evaporated moisture, such that the latent heat of evaporation can be recovered by the drying gas. The required operating power can then be much lower than the required power for evaporating the moisture contained in the sludge, because most of this power is recovered.
