What is a Roots Type Steam Compressor
There are also many types of steam compressors in the market. As far as MVR steam compressors are concerned, they can be divided into Roots-type steam compressors and single-stage high-speed centrifugal steam compressors. The stainless steel materials of Roots-type steam compressors generally produced in the market are SS304, S304, and S316L.
The core of MVR technology energy saving is to use the enthalpy of the secondary steam to increase its temperature through compression as a heat source to replace the fresh steam, that is, to add a part of the compressor work to achieve cyclic evaporation. Therefore, the purpose of evaporation and concentration can be achieved by relying on the self-circulation of the evaporation system without the need for external fresh steam. In this way, the steam to be discarded is fully utilized, latent heat is recovered, and thermal efficiency is improved.
When it comes to the structure of MVR Roots steam compressors, there are also many forms, such as belt drive, direct drive, in the evaporation industry, MVR Roots steam compressors are often operated in the vacuum range, the heating surface load is moderate, and the temperature difference Small, so Roots-type steam compressors are often used.
