An air-drying device for sludge comprises at least one air-drying mechanism, a dosing mechanism, and a dehumidifying and heating mechanism. There two air-drying mechanisms. The dosing mechanism connects with the beginning end of the first air-drying mechanism (5) whose terminal end communicates with the beginning end of the second air-drying mechanism (8), with a discharge port (21) is arranged above the communicating position. The terminal end of the second air-drying mechanism communicates with the beginning end of the first air-drying mechanism to form a loop configuration. The device has high efficiency and low energy consumption. The detention time of the sludge in the drying device is adjustable so that the water content of the discharging material is adjustable.

1. A device for air-drying sludge, comprising: at least one air-drying mechanism,a dosing mechanism, anda dehumidifying and heating mechanism, wherein the air-drying mechanism includes an axis blades and an engine, wherein the output shaft of the engine connects with the axis, wherein the blades are set on the axis, wherein the dosing mechanism connects with the beginning end of the air-drying mechanism, wherein the dehumidifying and heating mechanism includes a dehumidifying cool exchanger, a tail gas heat exchanger, a dehumidifying heat exchanger, an air warmer, a blower and a refrigeration compressor, wherein an air inlet connects with the dehumidifying cool exchanger, wherein the dehumidifying cool exchanger connects with the tail gas heat exchanger, wherein the tail gas heat exchanger connects with the dehumidifying heat exchanger via the blower, wherein the dehumidifying heat exchanger connects with the air warmer, and there is a condensate discharging pipe at the lower part of the dehumidifying cool exchanger, wherein the dehumidifying and heating mechanism is above the air-drying mechanism, wherein the outlet of the air warmer connects with the air inlet of the air-drying mechanism through a pipe, wherein an exhaust pipe on the top of the air-drying mechanism connects with an inlet manifold of the tail gas heat exchanger, and wherein an outlet manifold of the tail gas heat exchanger connects with a gas collector which has a condensate collecting pipe on the bottom and a tail gas outlet on the top. 2. The device of claim 1, wherein the rotate speed of the axis of the air-drying mechanism is between 0-30 rpm. 3. The device of claim 1, wherein the dosing mechanism includes a sludge storage container and a dosing screw transporter wherein the dosing screw transporter is under the sludge storage container. 4. The device of claim 3, wherein the rotate speed of the axis of the air-drying mechanism is between 0-30 rpm. 5. The device of claim 1, wherein there are two air-drying mechanisms, wherein the dosing mechanism connects with the beginning end of the first air-drying mechanism, while the terminal end thereof communicates with the beginning end of the second air-drying mechanism, with a discharge port arranged above the communicating position, and the terminal end of the second air-drying mechanism communicates with the beginning end of the first air-drying mechanism so that a loop configuration is formed. 6. The device of claim 5 wherein the rotate speed of the axis of the air-drying mechanism is between 0-30 rpm.
