air dehumidification; the air supply mechanism (3) sends saturated air with high humidity in the drying chamber (1) into the circulating chamber (2), the low-temperature component (22) reduces the temperature of the air, moisture in the air is condensed into water drops, and the high-temperature component (23) heats the low-temperature dried air into high-temperature dried air.
10. The sludge dewatering and drying construction method according to claim 9, characterized in that: in the step b, after the workers add the sludge into the drying chamber (1), the workers open the dust removal assembly (21), and the dust removal assembly (21) reduces the content of dust in the air supply pipeline (31).
