An air amount adjustment device is provided for adjusting a ratio between an amount of air to be fed to the driving section accommodating chamber via the air feeding passage and an amount of air to be discharged from the driving section accommodating chamber via the exhaust passage.

A dual-airflow cyclone flash drying device includes a feeding device, a fluidizing cyclone generator and a drying cylinder. The fluidizing cyclone generator is connected with the drying cylinder through a central connecting pipe. The tail end of the feeding device is provided with a porous plate doser that is connected with the central connecting pipe. The fluidizing cyclone generator adopts lateral air supply, air forms a cyclone along the circular outer wall to enter the central connecting pipe. A drying cyclone generator is arranged at the lower portion of the drying cylinder. The drying cyclone generator adopts lateral air supply, and after forming a cyclone, air spirally rises to make contact with fluidized granular sludge to evaporate sludge moisture into water vapor. A particle size selector is arranged at the upper portion of the drying cylinder, and an outlet flue is arranged above the particle size selector.

A heat pump dryer includes a main casing having an air inlet channel and an air outlet channel, a compressor, a first heat exchanger positioned in the air inlet channel, a second heat exchanger positioned in the air outlet channel, a fan provided in the air inlet channel, and an energy efficient heat exchanger. The energy efficient heat exchanger has a first portion partially exposed to the air inlet channel, and a second portion partially exposed to the air outlet channel. Air is arranged to enter the air inlet channel to sequentially perform heat exchange with the first portion of the energy efficient heat exchanger and the first heat exchanger. Air passing through the air inlet channel is arranged to enter the air outlet channel to sequentially perform heat exchange with the second portion of the energy efficient heat exchanger and the second heat exchanger.
