Power generation device and gas pressure conveying device manufactured through power generation device

The invention discloses a power generation device which comprises a sealing shell. A hollow ventilation shaft is arranged in the sealing shell in a penetrating manner. The two ends of the ventilationshaft stretch out of the sealing shell, the upstream end portion of the ventilation shaft communicates with an inlet gas pipe in a sealed manner through rotation, the inlet gas pipe communicates withan upstream gas source, and a solid rotating shaft is fixed to the downstream end portion of the ventilation shaft. A gas distribution chamber is arranged at the middle portion of the ventilation shaft. Multiple gas spraying nozzles are fixed in the gas distribution chamber in the radial direction of the ventilation shaft. The gas spraying nozzles are in a hollow arc shape, and the gas ways from the inlet gas pipe to the gas spraying ends of the gas spraying nozzles are smooth. The invention further discloses a gas pressure conveying device manufactured through the above power generation device. Compared with the prior
