The specific embodiment
Among the embodiment as shown in Figure 1; The described a kind of vacuum tube heat exchanger of the utility model; Comprise heat exchanger shell 1, boiler feedwater heating tube 7, said boiler feedwater heating tube 7 connects through bend pipe 14, and tilt be installed in heat exchanger shell 1 inside; Two ends are respectively cold water inlet 6 and the hot water outlet 5 that stretches out heat exchanger shell 1; Its outer cover is provided with the high-frequency welding boiler with seamless finned tube 10, and said high-frequency welding boiler is with being provided with steel wire 12 and heat-conducting liquid 11 being housed in the seamless finned tube 10, and said heat exchanger shell 1 middle part is provided with tube sheet 13 the vacuum tube heat exchanger is divided into two parts; The boiler feedwater heating tube 7 low part two ends, side place of its medium dip are respectively boiler smoke import 2 and boiler flue gas outlet 3; High part two ends, side place are respectively blast inlet 8 and air blast outlet 9, and said boiler smoke import 2 is in same end with blast inlet 8, and boiler flue gas outlet 3 is in same end with air blast outlet 9.Boiler feedwater heating tube 7 its angles of inclination that said inclination is installed are 5 °.Said heat exchanger shell 1 outer setting has heat-insulation layer 4.Said vacuum tube heat exchanger is provided with access door 15, and said access door 15 is provided with heat-insulation layer 4.On said cold water inlet 6 and the hot water outlet 5 flange is installed.
The described vacuum tube heat exchanger of the utility model is the environment-friendly energy-saving equipment that substitutes original economizer of boiler and air preheater.With tube sheet 13 heat exchanger shell is separated formation boiler flue heat absorption district and air blast heat release zone.Boiler exhaust gas gets into the vacuum tube heat exchanger by boiler smoke import 2 when boiler operatiopn.5 ° of high-frequency welding boilers of laterally placing of horizontal tilt are with seamless finned tube 10 in the heating heat exchanger housing 1.Heat-conducting liquid in the pipe is covered with the high-frequency welding boiler with seamless finned tube 10 under steel wire 12 capillary helps, and vaporization absorbs the heat energy in the boiler exhaust gas fast.Because of the high-frequency welding boiler with vacuumizing in the seamless finned tube 10.So heat-conducting liquid 11 can just be vaporized at short notice and given boiler feedwater heating tube 7 with thermal energy transfer.Boiler feedwater heating tube 7 condenses into liquid with the conductive fluid of vaporization again with the air blast heat release zone, flows to the bottom of high-frequency welding boiler with seamless finned tube 10 next time in the effect of conductive fluid self gravitation, circulation heat absorption evaporation.Boiler exhaust gas is discharged from boiler flue gas outlet 3 again.When giving boiler feed water, get into boiler feedwater heating tube 7 from vacuum tube heat exchanger bottom and go out to get into boiler from hot water outlet by cold water inlet 6.Boiler feedwater and boiler air blast are taken away the heat-conducting liquid vaporization simultaneously and are absorbed the heat energy in the boiler exhaust gas.And keep every high-frequency welding boiler with being identical negative pressure state in the seamless finned tube 10; Because of the vacuum tube heat exchanger is the indirect heating boiler condensed heat-conducting liquid that feeds water; Temperature is higher 60 ℃ than boiler feed temperature, remains on more than 70 ℃ with seamless finned tube 10 tube wall temperatures so can control every high-frequency welding boiler.And the acid dew point formation temperature is when 60 ℃ of tube wall temperatures.Boiler when operation boiler during topped up with water the boiler air blast continue to get into the air blast heat release zone by boiler drum wind inlet 8, discharge by boiler air blast outlet 9 again and take away the heat energy that heat-conducting liquid 11 vaporizations absorb in the boiler exhaust gas and remove boiler furnace and coal combustion.The vacuum tube heat exchanger can absorb the heat energy in the boiler exhaust gas.When boiler flue heat absorption district and air blast heat release zone are worked simultaneously in the vacuum tube heat exchanger, arrange can the boiler exhaust gas temperature be reduced to 120 ℃ with the vacuum tube heat exchanger of the identical heating surface area of economizer.
