Résumé

In the process of carbon neutralization, the traditional steam generation methods based on fossil energy (such as coal-fired boilers) will be faded out gradually. It can be predicted that the steam generation method based on electricity with renewable energy will become the main generation method of industrial steam. In this paper, according to the steam demand of pharmaceutical factory, an air source heat pump steam generation system is developed. The cascade air source heat pump is used to produce hot water at the temperature of 80-85°C, then the hot water flash to saturated steam at the temperature of 78-83°C. The saturated steam is extracted to a twin-screw steam compressor, and is pressurized to saturated temperature of 140-160°C. To ensure the purity of steam supplied, water lubricated mechanical seal is developed for the twin-screw steam compressor. When the softened water is used as sealing fluid, zero steam pollution is realized in the generation process. The operation data of the twin screw steam compressor show that the pressure and temperature of the supply steam are stable, the operation of mechanical seals is reliable. It has a good demonstration effect for the further engineering application of air source heat pump steam generation system.
