Steam boiler in use, entering a wind of burner hearth and the new water that supplements is the air of normal temperature and the water of normal temperature, the air of normal temperature and the water of normal temperature can reduce the temperature in the steam boiler body of heater after entering in the body of heater of the steam boiler that temperature is higher, and the efficiency of this steam boiler is not high.
In use, it is directly to be discharged to outside body of heater that the exhanst gas outlet of body of heater is discharged flue gas to steam boiler, and the temperature that body of heater is discharged flue gas is higher, and the higher flue gas of temperature contains certain heat energy.If the waste heat of high-temperature flue gas is passed to a wind that enters burner hearth and the new water that supplements, a wind that enters in body of heater can raise with the temperature of supplementing new water, the higher empty G&W of temperature, as the burner hearth that enters of a wind and the new water that supplements, can improve the efficiency of steam boiler.
At present, with the matching used smoke heat energy retracting device of steam boiler in, the waste-heat recovery device of useful high-temperature flue gas heating normal-temperature water, also useful high-temperature flue gas heats the waste-heat recovery device of normal temperature air, waste-heat recovery device is shell and tube or jacket type, and these steam boiler waste heat recovering devices are single.In prior art, do not have to heat the compound waste-heat recovery device of steam boiler that normal-temperature water also can heat normal temperature air.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, proposes a kind ofly can heat the compound waste-heat recovery device of steam boiler that normal-temperature water also can heat normal temperature air.
The utility model is realized with the following method.
The compound waste-heat recovery device of steam boiler has vertical smoke discharging housing, there is smoke inlet the top of smoke discharging housing, there is exhanst gas outlet the below of smoke discharging housing, in the smoke discharging housing, tubulation is arranged, the upper end mouth of pipe of tubulation stretches out from the top of smoke discharging housing, and the lower end mouth of pipe of tubulation stretches out from the below of smoke discharging housing through discharge, and there is chuck in the outside of smoke discharging housing, there is water inlet the below of chuck, and there is delivery port the top of chuck.
During installation, smoke inlet of the present utility model is connected with the exhanst gas outlet of steam boiler, exhanst gas outlet of the present utility model is connected with air inducing, the discharge mouth of pipe that the utility model is stretched out to smoke discharging housing below is connected with a wind entrance of steam boiler, water inlet of the present utility model is connected with feed pipe, delivery port of the present utility model is connected with the filler of steam boiler.
During use, coal is in the burner hearth internal combustion, and the high-temperature flue gas that steam boiler produces is discharged from exhanst gas outlet, enters in the smoke discharging housing, between the pipe of tubulation, flows, and through air-introduced machine, draws discharged to chimney; After air-introduced machine is drawn high-temperature flue gas, produce negative pressure in burner hearth, normal temperature air sucked from the tubulation mouth of pipe that stretches out smoke discharging housing top, normal temperature air in the pipe of tubulation, a wind entrance of discharge and steam boiler enters the burner hearth of steam boiler; Feed pipe in chuck for normal-temperature water, normal-temperature water after chuck flows out again in the filler of delivery port of the present utility model and steam boiler joins the burner hearth of steam boiler; When normal temperature air flows in pipe, can absorb the high-temperature flue gas heat that flows in the smoke discharging housing and heat up; When normal-temperature water flows through chuck, can absorb the high-temperature flue gas heat that flows in the smoke discharging housing and heat up.
The utility model has the smoke discharging housing, in the smoke discharging housing, tubulation is arranged, the smoke discharging housing has chuck outward, and the high-temperature flue gas of steam boiler, after the smoke discharging housing is discharged, can heat the normal temperature air in tubulation in the smoke discharging housing and can heat again the normal-temperature water in smoke discharging housing external jacket.Be a kind of compound waste-heat recovery device of boiler furnace, can reclaim efficiently and utilize the waste heat in the high-temperature flue gas that steam boiler discharges.With the wind of the normal temperature air after heating as steam boiler burning use, with the normal-temperature water after heating, as the steam boiler supplementing water, can effectively improve the thermal efficiency of steam boiler.
Below in conjunction with accompanying drawing, the utility model is further described.
