Detailed description of the invention
For making to have a better understanding and awareness architectural feature of the present utility model and effect of reaching, coordinating detailed description in order to preferred embodiment and accompanying drawing, being described as follows:
As shown in Figure 1, the raw water heater steam drainage recovery device for boiler feed water system described in the utility model, comprises main building jet chimney 16.Main building jet chimney 16 accesses raw water heater 1, and between main building jet chimney 16 and raw water heater 1, be provided with pneumatic stopping valve 19, steam control valve 20 and check-valves C21.Raw water heater 1 picks out steam drainage outlet pipe 5, steam drainage outlet pipe 5 is connected to hydrophobic dirt-removing pipe 6, and hydrophobic dirt-removing pipe 6 accesses hyperfiltration reverse-rinsing and reclaims pond 4.It is outdoor hypogee that hyperfiltration reverse-rinsing reclaims pond 4, processes for collecting sewage and delivering to boiler feedwater Raw water treatment system by waste water pump.Hydrophobic dirt-removing pipe 6 being provided with manual diaphragm valve 11, for controlling, the underproof hydrophobic hyperfiltration reverse-rinsing that drains into being reclaimed pond 4.
Steam drainage outlet pipe 5 is provided with drain valve 8 and electric conductive meter 15, drain valve 8 is for controlling steam drainage outlet pipe 5, and electric conductive meter 15 is for detecting the change of hydrophobic electrical conductivity in steam drainage outlet pipe 5.Steam drainage outlet pipe 5 accesses pro desalting water tank 2, pro desalting water tank 2 is connected to chemical deionization system pipeline 17, the water of pro desalting water tank 2 enters chemical deionization system and uses.Steam drainage outlet pipe 5 use threeway be connected to bypass duct 7, bypass duct 7 is between pro desalting water tank 2 and hydrophobic dirt-removing pipe 6, bypass duct 7 accesses ultrafiltration water tank 3, ultrafiltration water tank 3 is connected to counter-infiltration system pipeline 18, and the water of ultrafiltration water tank 3 enters counter-infiltration system and uses.Steam drainage outlet pipe 5 is positioned at pro desalting water tank 2 import department and pneumatic diaphragm valve A9 and check-valves A12 is installed, whether pneumatic diaphragm valve A9 enters pro desalting water tank for control in steam drainage outlet pipe 5 hydrophobic, and check-valves A12 can not pour in down a chimney for the water controlled in pro desalting water tank 2 and enters in steam drainage outlet pipe 5.Bypass duct 7 is positioned at ultrafiltration water tank 3 import department and is provided with pneumatic diaphragm valve B10 and check-valves B13, pneumatic diaphragm valve B10 is identical with check-valves A12 with pneumatic diaphragm valve A9 with the effect of check-valves B13.
Steam drainage outlet pipe 5 is provided with heat indicator 14, heat indicator 14 is between drain valve 8 and electric conductive meter 15, and the data output end of heat indicator 14 is connected with the data input pin of electric conductive meter 15.Electric conductive meter 15 has temperature compensation function, electric conductive meter 15 for detecting the change of hydrophobic middle electrical conductivity, and according to the detection signal of heat indicator 14, the electrical conductivity signal under adopting temperature compensation function automatically to export reference temperature.Pro desalting water tank 2 and ultrafiltration water tank 3 are outdoor arrangement and are highly about about 6m, because hydrophobic pressure is less, as shown in Figure 2, the pipeline absolute altitude of steam drainage outlet pipe 5 between drain valve 8 and pro desalting water tank 2, higher than the height of pro desalting water tank 2, ensures that the hydrophobic acquisition sufficiently high pressure of steam after raw water heater 1 heat exchange can enter pro desalting water tank 2.In like manner, the pipeline absolute altitude of steam drainage outlet pipe 5 between drain valve 8 and pro desalting water tank 2, also higher than the height of ultrafiltration water tank 3, ensures that the hydrophobic acquisition sufficiently high pressure of steam after raw water heater 1 heat exchange can enter ultrafiltration water tank 3.
