Abstract
The utility model discloses a kind of Air-cooled Unit high back pressure circulating water heating gland heater bypath system, gland heater is connected with unit condensate line, it is characterized in that: also comprise the bypath system that heat supply network water return pipeline is connected with gland heater, wherein gland heater arrival end connects unit condensate line by valve A, connects heat supply network supply channel by valve B; The gland heater port of export connects unit condensate line by valve C, connects heat supply network supply channel by valve D.When the utility model runs, gland heater utilizes heat supply network backwater cooling shaft gland leak-off, both ensure that the ability to work of gland heater, and reclaimed again the waste heat of gland packing leakage, economize energy, security is high.
Description
Technical field
The utility model relates to heat supply process field, is specifically related to a kind of Air-cooled Unit high back pressure circulating water heating gland heater bypath system.
Background technology
Air-cooled Unit high back pressure circulating water heating utilizes the original design high back pressure of Air-cooled Unit to carry out heat supply, be 33kPa in heat supply phase unit operation back pressure, corresponding condensing water temperature is 71.3 DEG C, when unit design runs back pressure 12kPa, condensing water temperature 49.4 DEG C, heat supply phase unit longtime running is under high back pressure 33kPa operating mode, and gland heater cooling capacity is not enough, can cause unit gland packing leakage.
Summary of the invention
For making up the deficiencies in the prior art, the utility model provides a kind of structure simple, Air-cooled Unit high back pressure circulating water heating gland heater bypath system reasonable in design.
The utility model is achieved by the following technical solution:
A kind of Air-cooled Unit high back pressure circulating water heating gland heater bypath system, gland heater is connected with unit condensate line, its special character is: also comprise the bypath system that heat supply network water return pipeline is connected with gland heater, wherein gland heater arrival end connects unit condensate line by valve A, connects heat supply network supply channel by valve B; The gland heater port of export connects unit condensate line by valve C, connects heat supply network supply channel by valve D.
The beneficial effects of the utility model are: when thermal power plant unit high back pressure runs, open Air-cooled Unit high back pressure circulating water heating gland heater bypath system, now gland heater utilizes the heat supply network backwater of 50 DEG C to carry out cooling shaft gland leak-off, namely ensure that the ability to work of gland heater, reclaim again the waste heat of gland packing leakage.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing 1 is structural representation of the present utility model.
In figure, 1 gland heater, 2 unit condensate lines, 3 heat supply network supply channels, 4 valve A, 5 valve B, 6 valve C, 7 valve D.
Detailed description of the invention
Accompanying drawing is a kind of detailed description of the invention of the present utility model.Gland heater 1 is connected with unit condensate line 2, also comprise the bypath system that heat supply network water return pipeline 3 is connected with gland heater 1, wherein gland heater 1 arrival end connects unit condensate line 2 by valve A4, connects heat supply network supply channel 3 by valve B5; Gland heater 1 port of export connects unit condensate line 2 by valve C6, connects heat supply network supply channel 3 by valve D7.
In order to ensure the ability to work of unit gland heater when heat supply phase high back pressure runs, when heat supply phase unit high back pressure runs, valve-off 4 and valve 6, open valve 5 and valve 7, this Air-cooled Unit high back pressure circulating water heating gland heater bypath system of unit operation.Now gland heater utilizes the heat supply network backwater of 50 DEG C to carry out cooling shaft gland leak-off, namely ensure that the ability to work of gland heater, has reclaimed again the waste heat of gland packing leakage.
