Dehumidification heat pump sludge dryer makes use of dehumidification heat pump to carry out the sludge through hot-air recycling, condensing, dehumidifying and drying. The evaporation of the sludge moisture produces latent heat. And the condensation of vapor on heat pump requires latent heat as well.

Sludge is a residual, semi-solid by-product left from industrial or refining processes. It is a separated solid suspended in a liquid, typically containing major quantities of interstitial water between its solid particles. This material can be dried to cut its volume and reduce most of the moisture content of the biosolids present in the sludge.

This dryer technology can only work correctly if the sludge entering the dryer is pre-granulated and has a dry content higher than 65% DM. Therefore, intensive recirculation of a portion of dried sludge with raw sludge is necessary in a specific mixer/granulating machine. In terms of operation this is a difficult stage.

Paddle dryers are based on externally-heated paddles (or blades) rotating in the mass of sludge solids. There are normally either two or four sets of blades which rotate together to continuously cut into and stir the sludge solid lumps into smaller particles to continuously replenish the drying surface.

Fluidized bed dryers for drying dewatered sewage sludge operate in a closed inert gas loop. The entire heat required to evapo - rate the water is fed to the dryer via heat exchangers, i.e. without any direct contact between the heat transfer medium and the product. The dewatered sewage sludge is pumped directly to the fluidized bed dryer ...
