Title:
HEAT RECOVERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/249670
Kind Code:
A1
Abstract:
This heat recovery system (100) is provided with: water-sealed header tank (2) where drainage generated by equipment that uses steam flows in and is stored; a liquid pumping device (5) which has a casing (50) having a drainage storage chamber (51) and a steam exhaust port (55) formed therein, and which performs an inflow operation which, by discharging the steam in the storage chamber (51) from the exhaust port (55), causes drainage of the header tank (2) to flow into and be stored in the storage chamber (51), and a pumping operation which, by introducing steam into the storage chamber (51), pumps drainage of the storage chamber (51); and a pathway switching unit (6) which has a first pathway for supplying to the header tank (2) steam discharged from the exhaust port (55) and a second pathway for supplying said steam to a first flow path (41) of a heat exchanger (4) different from the header tank (2), and which, during inflow operation, selectively switches to the first pathway or the second pathway depending on the discharge pressure, which is the pressure of the steam discharged from the exhaust port (55).
