MULTI STAGE COMPRESSOR FOR VAPOR RECIRCULATION

摘要

A multi-stage compressing device for re-circulating steam according to the present invention includes: a compressing unit formed to include at least three compressor, compressing waste stem discharged from a plant at a high temperature and a high pressure in multiple stages, and returning the compressed steam back to the plant; a low-temperature condensate tank receiving low-pressure condensate discharged between a first compressor and a second compressor; and a high-pressure condensate tank receiving high-pressure condensate discharged between the second compressor and a third compressor. The multi-stage compressing device for re-circulating the steam according to the present invention enables the waste steam discharged from the plant to be reused by compressing the waste steam at a high temperature and a high pressure in the multiple stages and enables the condensate generated during the process of compressing the waste steam to be reused by separating the condensate into the high-temperature steam and the low-temperature water and returning the high-temperature steam back to the plant, thereby improving the energy efficiency of the plant and reducing environmental pollution.
