Title:
SWITCHING SYSTEM FOR HIGH-BACKPRESSURE HEAT SUPPLY CIRCULATING WATER SYSTEM AND WATER TOWER CIRCULATING WATER SYSTEM OF THERMAL POWER PLANT
Document Type and Number:
WIPO Patent Application WO/2021/203747
Kind Code:
A1
Abstract:
A switching system for a high-backpressure heat supply circulating water system and a water tower circulating water system of a thermal power plant, comprising the high-backpressure heat supply circulating water system, the water tower circulating water system, a water cooling tower, circulating water pumps, and a condenser (30). Left and right sides of the condenser (30) are isolated to implement independent operation; a first water pipe (3) is led out behind a valve (2) of a B-side circulating water pump (1); a first valve (4) is added to the first water pipe (3); a second water pipe (5) and a third water pipe (6) are respectively led out behind the first valve (4); the second water pipe (5) is connected to an A-side water outlet pipe (8) of an A-side circulating water pump (7), a joint is located behind a valve (9), and a second valve (10) is added to the second water pipe (5); the third water pipe (6) is connected to a C-side water outlet pipe (12) of a C-side circulating water pump (11), a joint is located behind a valve (13), and a third valve (14) is added to the third water pipe (6). The benefit is maximized when a steam temperature is high in the primary and final stages of a heat supply season.
