Preferably, described aqueous vapor heat exchanger is between described gas-gas heat exchanger and described boiler.
Preferably, the other end of described combustor and described gas-gas heat exchanger also is connected with a natural airduct.
Preferably, the both sides of described first water pump and described second water pump are equipped with a valve.
Preferably, described softened water tank also is connected to the running water treatment facility.
Compared with prior art, pharmacy corporation gas fired-boiler residual neat recovering system of the present utility model has promoted the temperature of boiler feed water and boiler air intake, improve the efficiency of combustion of boiler greatly, utilized the waste heat of boiler combustion fully, reduced the influence to environment.
By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.
Description of drawings
Fig. 1 is the schematic diagram of the utility model pharmacy corporation gas fired-boiler residual neat recovering system.
The specific embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, the similar elements label represents similar elements in the accompanying drawing.
Please refer to Fig. 1, described pharmacy corporation gas fired-boiler residual neat recovering system comprises boiler 1, softened water tank 2, waste-heat recovery device 3, outlet pipe 4, first water pump 5, return pipe 6, water inlet pipe 7, second water pump 8, airduct 9, blower fan 10 and electrical control cubicles 11.
The lower end of described boiler 1 is provided with combustor 100, and the upper end of described boiler 1 is provided with smoke pipe 120.Described waste-heat recovery device 3 is arranged on the described smoke pipe 120, and described waste-heat recovery device 3 is made up of gas-gas heat exchanger 300 and aqueous vapor heat exchanger 320, and described aqueous vapor heat exchanger 320 is between described gas-gas heat exchanger 300 and described boiler 1.Described softened water tank 2 connects described first water pump 5 and described aqueous vapor heat exchanger 320 successively via described outlet pipe 4, described aqueous vapor heat exchanger 320 is connected to described softened water tank 2 via described return pipe 6, described softened water tank 2 also connects described second water pump 8 and described boiler 1 successively via described water inlet pipe 7, the both sides of described first water pump 5 and described second water pump 8 are equipped with a valve 12, and described softened water tank 2 also is connected to the running water treatment facility.One end of described gas-gas heat exchanger 300 is connected to an end of described combustor 100 via described airduct 9, and the other end of described combustor 100 and described gas-gas heat exchanger 300 also is connected with a natural airduct 13.Be provided with described blower fan 10 in the described airduct 9, described combustor 100 and described first water pump 5 and 10 interlocks of described blower fan, described electrical control cubicles 11 connects the control signal wire of described first water pump 5, second water pump 8, combustor 100 and blower fan 10.
The principle of pharmacy corporation gas fired-boiler residual neat recovering system is as follows:
When normal the use, when described boiler 1 needed water inlet, the enabled instruction of assigning second water pump 8 by described electrical control cubicles 11 was finished the water conservancy project that adds of boiler 1 and is done.
When boiler normally starts, two valves 12 on the described outlet pipe 4 are opened in advance, described combustor 100 and 5 interlocks of first water pump, when combustor 100 operations, 5 operations of first water pump, soft water passes through described outlet pipe 4, described first water pump 5 and described aqueous vapor heat exchanger 320 successively, get back to described softened water tank 2 through described return pipe 6 after in described aqueous vapor heat exchanger 320, carrying out heat exchange, so circulation enters the soft water of boiler 1 with heating, and the smoke pipe exhaust gas temperature of boiler tail from 170 ℃ by dropping to about 100 ℃ behind the aqueous vapor heat exchanger.Secondly we improve the efficiency of combustion of boiler by the method for temperature that promotes the boiler air intake.
