[0075] A rotating shaft 320d is installed in the inner cavity of the eccentric turntable 320c along the axial direction of the eccentric turntable 320c. The rotating shaft 320d is coaxial with the eccentric turntable 320c and eccentrically set with the second housing 320a. The rotating shaft 320d passes through the eccentric turntable 320c and the second housing 320a and is detachably connected to the drive shaft 310c. The rotating shaft 320d is connected to the second housing 320a through a bearing. The rotating shaft 320d is connected to the eccentric turntable 320c through a spline or a flat key. The drive shaft 310c drives the rotating shaft 320d to rotate, and the rotating shaft 320d drives the eccentric turntable 320c to rotate in the inner cavity of the second housing 320a.

[0076] Guide plates 320d-1 are evenly arranged on the outer circumferential wall of the rotating shaft 320d. The guide plates 320d-1 are integrally formed with the rotating shaft 320d.

As the rotating shaft 320d rotates, it drives the telescopic plate 320d-2 to make a circular motion. The telescopic plate 320d-2 extends and retracts back and forth under the constraint of the inner circumferential side wall of the second housing 320a.

[0080] Steam in the inner cavity of the recovery tank 100 enters the inner cavity of the second outer shell 320a through the air inlet 320a-1, and is driven to flow through the inner cavity of the second outer shell 320a by the telescopic plate 320d-2 and discharged through the exhaust port 320a-2.

[0082] The air inlet 410 is connected to the exhaust port 320a-2 through a pipe. Steam is injected into the inner cavity of the compression box 400 through the air inlet 410 for compression. The compression mechanism 320 can compress the steam into the inner cavity of the compression box 400. At the same time, the structure of the compression mechanism 320 can ensure that the steam backflow phenomenon is avoided. The steam is compressed in the inner cavity of the compression box 400, increasing the temperature of the steam.

[0083] The exhaust port 420 is connected to the heating pipe 140 through a pipe. An air valve is installed between the exhaust port 420 and the heating pipe 140 to periodically discharge compressed steam into the inner cavity of the heating pipe 140, and then spray it into the wastewater through the nozzle 140a to further increase the temperature of the wastewater. The compressed steam comes into direct contact with the wastewater, avoiding heat loss caused by traditional heat exchange, improving the heating efficiency of the wastewater, and indirectly increasing the temperature of the boiler feedwater pool. This can further effectively save energy and reduce consumption, lower costs, and improve resource utilization.

The flocculant enters the inner cavity of the heating pipe 140 through the discharge port 510b. Driven by the pressure of the steam compressed in the inner cavity of the compression box 400, it is sprayed out from the nozzle 140a. The wastewater is stirred by air pressure, and the flocculant is mixed into the wastewater to flocculate the wastewater, remove impurities in the wastewater, and prevent impurities in the wastewater from settling in the coils connected to the boiler feedwater pool, thereby improving the service life.
