method of managing hot water streams and heat storage in a wastewater purification plant and factory by implementing said method

摘要

method according to which the produced hot water streams are collected in a common accumulator (7) of sufficient height to form stratified water layers at decreasing temperatures from a temperature of at least 90 ° C to high part to about 40 ° c low part; the produced hot water streams are introduced (6, 30, 47, ve, vf, vg) into the accumulator (7) at different levels whose temperatures substantially correspond to those of the introduced streams; hot water withdrawals (vd, va, vb, vc) for different consuming equipment are provided at different levels whose temperatures correspond substantially to those desired to feed the heating consuming equipment with hot water; and a valve control system (d) is provided at least over withdrawals to ensure the management and thermal equilibrium of heat flows in and out of the accumulator, and to smooth out variations in heat input and requirements.
