Roots vapor compressor with buffering chamber

Abstract

The invention provides a Roots vapor compressor with a buffering chamber and belongs to the technical field of mechanical steam compression. The Roots vapor compressor comprises a vapor inlet, an inlet flange, a compression chamber, the buffering chamber, a partition plate, a vapor outlet, an outlet flange, a fixing base and an exhaust opening. The buffering chamber is arranged behind the compression chamber so that the pressure fluctuation influence caused during impeller stirring can be reduced, loads of the impeller are stabilized, and the vibration and noise problems of the Roots vapor compressor are effectively solved; and due to the arrangement of the partition plate in the buffering chamber and with the combination of the design that the structure stretching in the buffering chamberis adopted on the vapor outlet and the design of exhaust hole, impurities with the large specific gravity and saturated vapor in mixed vapor can be separated, and recycling of waste vapor can be better facilitated. The Roots vapor compressor has the beneficial effects that the structure is simple, the cost is low, and maintenance is convenient; the Roots vapor compressor can be widely applied tooccasions where vapor compressors are used for recycling waste heat of waste vapor in relevant industries with steam condensation production technologies, and energy saving and environment protectioneffects are effectively improved.

Description

technical field [0001] The invention relates to a Roots vapor compressor, in particular to a Roots vapor compressor with a buffer chamber. It belongs to the technical field of mechanical vapor compression. Background technique [0002] Roots steam compressor is generally used in the waste heat recovery system to compress the secondary waste steam and increase the temperature and pressure of the secondary waste steam, which is the key equipment to realize the recovery and utilization of waste steam. Roots vapor compressors generally adopt a three-leaf or two-leaf structure, and the blades rotate at a constant speed. When the blades rotate for steam compression, due to the different positions of the blades, the discharge speed of the compressed steam changes periodically, so It will cause the outlet steam pressure to fluctuate periodically, which is also one of the reasons for vibration and noise, and it is also not conducive to the utilization of subsequent steam. In additi...
