Steam compressor pressure buffer separation device

Abstract

The invention provides a pressure buffering separation device for a steam compressor and belongs to the technical field of mechanical vapor compression. The pressure buffering separation device comprises a buffering separation room, a storage room, a steam inlet pipeline, a steam outlet pipeline, a discharge opening, a transverse partition and a longitudinal partition. The pressure buffering separation device is directly connected behind the steam compressor, so that the outlet space of compressed steam is greatly increased, and the problems of vibration and noise of the steam compressor are effectively solved. The steam inlet pipeline and the steam outlet pipeline adopt special semi-cylindrical structural designs. Together with the transverse partition and the longitudinal partition, ingredients with different densities in mixed steam are effectively separated, so that a favorable support is provided for follow-up recovery and heat exchange utilization of waste steam, and corrosion offollow-up steam pipelines and equipment is relieved. The pressure buffering separation device has the advantages of simple structure, low cost, convenient maintenance and repair, convenient upgradingand modification and the like, and can be extensively applied to occasions where steam compressors are utilized for waste heat recycling in related industries employing evaporation and concentrationproduction processes. Thus, the energy-saving and environment-friendly effect is effectively improved.

Description

technical field [0001] The invention relates to a steam compressor pressure buffering and separating device, in particular to a steam compressor outlet pressure buffering and impurity separating device. It belongs to the technical field of mechanical vapor compression. Background technique [0002] Mechanical steam compressors are generally used in waste heat recovery systems to compress secondary waste steam to increase the temperature and pressure of secondary waste steam, and are key equipment to realize waste steam recovery and utilization. A typical Roots steam compressor generally adopts a three-leaf or two-leaf structure, and the blades rotate at a constant speed. When the blades rotate to compress the vapor, the discharge speed of the compressed steam changes periodically due to the different positions of the blades. , so it will lead to periodic fluctuations in the outlet steam pressure, which is also one of the main reasons for vibration and noise, and it is also ...
