Embodiment
Describe specific embodiment of the present utility model in detail with reference to the accompanying drawings.
As shown in figure 1, the utility model is provided with boiler 1, heat exchange box 2, water tank 3, deduster 4 and water tank 5, boiler 1 fires Water in heat exchange box 2 is heated and fed in water tank 5 by flue gas caused by burning, is needed in boiler plus during water, then by water from storage It is depressed into wherein in water pot 5.
The top of heat exchange box 2 is provided with opening 6, and 6 top of being open is provided with water inlet pipe 7, water inlet pipe 7 by the first water pump 8 with Water tank 3 is connected, and the water in water tank 3 is entered in heat exchange box 2 in the presence of the first water pump 8 by water inlet pipe 7 by opening 6.
Forniciform heat exchanger tube 9 back and forth is provided with heat exchange box 2, the front end of heat exchanger tube 9 is stretched out from the side wall upper part of heat exchange box 2 It is connected with the outlet flue of boiler 1, the tail end of heat exchanger tube 9 stretches out from the lower sidewall of heat exchange box 2 to be connected with deduster 4, so, pot By swapping its heat and the water in heat exchange box 2 during heat exchanger tube 9, the flue gas after heat exchange passes through flue gas caused by stove burning Discharged after the dust separation of deduster 4.Deduster 4 can select any general dust arrester in the prior art.
The heat exchange box of existing economizer is all closing, and the temperature of water can reach 50-100 ° after heat exchange, volume after water is heated Become big to be easy to impact casing or even explode, potential safety hazard is larger, and the utility model is opened by setting at top Mouth 6, has fully ensured that its security.Heat exchanger tube 9 is using the high-temperature steel tube bent back and forth, and thickness of pipe wall is only 3-4mm, and this is all significantly Add its heat exchange efficiency.In addition, heat exchanger tube 9 of the present utility model is the top air inlet from heat exchange box 2, lower section outlet, we Know that gas is all up walked, so descending setting adds its residence time in heat exchanger tube 9, further ensures Heat transfer effect.
The bottom of heat exchange box 2 is connected by outlet pipe 11 with water tank 5, the water after heat exchange enter to it is standby in water tank 5, Outlet valve is also provided with outlet pipe 11;Water tank 5 is connected by pipeline with boiler 1, and connected pipeline is provided with the second water Pump 12.When needing to add water in boiler 1, the second water pump 12, which works, beats the hot water in water tank 5 to boiler 1.
Heating rod 13 is additionally provided with water tank 3, when being badly in need of substantial amounts of steam, heating rod 13 can be in advance by the water of water tank 3 Heating, steam then is produced by entering heating in boiler 1 after heat exchange again, the time caused by steam is shortened, improves efficiency.Change Some fins 14 are additionally provided with the outer wall of heat pipe 9, which in turns increases heat exchange area, improves heat exchange efficiency, fin 14 can Think variously-shaped.Due to easily carrying material by flue gas by the flue gas of high heat, heat exchanger tube 9 for a long time in heat exchanger tube 9 Abrasion, the utility model is provided with wear-resistant coating in the inwall of heat exchanger tube 9, substantially prolongs its service life, and wear-resistant coating can be with Using general wear-resisting in the prior art and resistant to elevated temperatures coating.
