The invention discloses a centrifugal compressor with a vibratory diffuser blade. The centrifugal compressor comprises an air incoming chamber, an impeller, a diffuser, a curve, a return flow device and a volute, the diffuser blade for diversion is arranged in the diffuser and connected with a partition through a diffuser blade rotating shaft, and a vibration exciter is connected with the diffuser blade through a transmission mechanism. When the vibration exciter works, vibration is generated and transmitted to the diffuser blade, and the diffuser blade vibrates around the diffuser blade rotating shaft and actively controls a flow field in the diffuser; or the diffuser blade is connected with an elastic element through the transmission mechanism, and when gas flows through the diffuser, the diffuser blade generates self-excited vibration to realize self-adaptive control on the flow field in the diffuser. In the constantly-changing flow field, the blade slightly vibrates around a rotating shaft, a runner is enabled to be capable of effectively adapt to flowing change, separation in flowing is reduced, energy loss is lowered, and overall performance of the diffuser is improved.

The invention discloses an ethylene unit alkaline washing tower polymer inhibitor and a preparation method and application thereof, which aim to solve the problems of the generation of an ethylene alkaline washing tower polymer and tower tray blockage in the prior art. The inhibitor consists of the following components in percentage by weight: 10 to 30 percent of a component A, 10 to 30 percent of a component B, 2 to 10 percent of a component C and 30 to 78 percent of a component D, wherein the component A is an aldehyde ketone condensation inhibitor; the component B is a water-soluble free radical polymerization inhibitor; the component C is a sulfate water-soluble antioxidant solubilizer; and the component D is a solvent. The ethylene unit alkaline washing tower polymer inhibitor has even and stable state and reliable performance, not only can inhibit aldehyde ketone condensation reaction and unsaturated olefin free radical polymerization reaction, but also can reduce a small amountof oxygen dissolved in an alkali liquor, and simultaneously disperses a small amount of the generated polymer and dissolves the polymer into the alkali liquor to prevent the polymer from blocking thetower tray.

The invention discloses an accurate agricultural seed fertilizing device.
