Document Type and Number:
WIPO Patent Application WO/2017/000588
Kind Code:
A1
Abstract:
Disclosed is a complete set of highly stable anti-corrosive heat supply systems, comprising a primary indirect supply system and a secondary indirect supply system. Injection pumps (10) are equipped on water supply pipes at the sides of heat exchange stations of the primary indirect supply system or on primary water supply pipes (9) of heat exchangers (11) of combined heat exchange sets (I) in the heat exchange stations. Using the injection pumps, part of the primary return water is sucked back to the primary water supply pipes (9), then is mixed with the primary supply water, and finally enters the heat exchangers (11). An anti-corrosive water mixing pipe (4) is equipped between a main outlet pipe (3) for a boiler and a main pipe (26) for primary return water. The secondary indirect supply system is connected to the secondary ends of the heat exchangers (11). The secondary indirect supply system mainly comprises powerless water mixing and heat exchange stations (II) of all heat user buildings, and injection pumps (16) equipped at heat inlets of all the heat user buildings. Using the injection pumps, part of the secondary return water is sucked back to the secondary water supply pipes, then is mixed with the secondary supply water, and finally enters the heat user buildings. Further disclosed is a direct supply system.
