Exchanged heat, the 23t/h that condensation end drum V1 is provided, 620kpa (g) saturations condensate liquid enters heat exchanger E1 by the pipeline that is connected
After be heated to form 165 DEG C of saturated vapors, the saturated vapor after heating enters refrigeration unit C1 by the pipeline that is connected, so that by heat energy
Be converted to 20000KW colds.The present invention can carry out waste heat recovery refrigeration, save production cost, securely and reliably, will not cause
Production accident, and greatly saved the primary energy for freezing.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that those skilled in the art should for clarity
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
