Description
Technical field
This utility model relates to heating equipment technical field, the combination unit that especially a kind of gas-steam boiler and the smoke discharging residual heat degree of depth are recycled.
Background technology
Boiler is a kind of energy conversion, and the energy to boiler input has the chemical energy in fuel, electric energy, and boiler output has the steam of certain heat energy, high-temperature water or organic heat carrier.The original meaning of pot refers to the water container of heating on fire, and stove refers to the place of burning fuel, and boiler includes pot and stove two large divisions.The hot water produced in boiler or steam directly can provide required heat energy for commercial production and people's lives, it is possible to be converted to mechanical energy by Steam Power Equipment, or convert mechanical energy into electric energy again through electromotor.The boiler providing hot water is called hot-water boiler, is mainly used in life, also has a small amount of application in commercial production.The boiler producing steam is called steam boiler, is often simply called boiler, is used for thermal power station, boats and ships, locomotive and industrial and mining establishment.
Boiler of the prior art, its recovery utilization rate is low, often results in the waste of energy.
Utility model content
The applicant is for the shortcoming in above-mentioned existing production technology, it is provided that the combination unit that a kind of gas-steam boiler and the smoke discharging residual heat degree of depth are recycled, and thereby through three air preheater effects, reaches energy-conservation effect.
The technical scheme that this utility model adopts is as follows:
The combination unit that a kind of gas-steam boiler and the smoke discharging residual heat degree of depth are recycled, including boiler, the outlet flue place of described boiler connects a vertically arranged afterheat heat exchanger by the first pipeline, the bottom of a described afterheat heat exchanger connects No. two horizontally disposed afterheat heat exchangers by the second pipeline, and the outside of a described afterheat heat exchanger and No. two afterheat heat exchangers is provided with water inlet and outlet；The delivery outlet of described No. two afterheat heat exchangers is connected to air preheater by the 3rd pipeline, the top of described air preheater connects No. three afterheat heat exchangers, the top of described No. three afterheat heat exchangers connects No. four afterheat heat exchangers by the 4th pipeline, and the bottom sides of described No. four afterheat heat exchangers is provided with outlet.
Its further technical scheme is in that:
Described No. three afterheat heat exchangers and No. four afterheat heat exchangers are and are arranged vertically, and No. three afterheat heat exchangers are parallel with No. four afterheat heat exchangers, and the installation site of No. three afterheat heat exchangers is higher than the installation site of No. four afterheat heat exchangers.
The beneficial effects of the utility model are as follows:
This utility model compact conformation, rationally, easy to operate, four afterheat heat exchanger tandem workings, the flue gas in pot is progressively heated, every afterheat heat exchanger can control each set temperature respectively.Heat transfer heating efficiency is high, good energy-conserving effect.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1, the combination unit that the gas-steam boiler of the present embodiment and the smoke discharging residual heat degree of depth are recycled, including boiler 1, outlet flue 2 place of boiler 1 connects a vertically arranged afterheat heat exchanger 4 by the first pipeline 3, the bottom of a number afterheat heat exchanger 4 connects horizontally disposed No. two afterheat heat exchanger 6 by the second pipeline 5, and the outside of an afterheat heat exchanger 4 and No. two afterheat heat exchangers 6 is provided with water inlet and outlet；The delivery outlet of No. two afterheat heat exchangers 6 is connected to air preheater 8 by the 3rd pipeline 7, the top of air preheater 8 connects No. three afterheat heat exchangers 9, the top of No. three afterheat heat exchangers 9 connects No. four afterheat heat exchangers 11 by the 4th pipeline 10, and the bottom sides of No. four afterheat heat exchangers 11 is provided with outlet 12.
No. three afterheat heat exchangers 9 and No. four afterheat heat exchangers 11 are and are arranged vertically, and No. three afterheat heat exchangers 9 are parallel with No. four afterheat heat exchangers 11, and the installation site of No. three afterheat heat exchangers 9 is higher than the installation site of No. four afterheat heat exchangers 11.
In actually used process, the flue gas produced in boiler 1 is discharged from outlet flue 2, enter into an afterheat heat exchanger 4 by the first pipeline 3 to be heated, enter back into No. two afterheat heat exchangers 6 after heating to be heated, then pass through air preheater 8 to be operated, sequentially enter No. three afterheat heat exchangers 9 again and No. four afterheat heat exchangers 11 are heated, finally discharge from outlet 12.Its good energy-conserving effect, recovery utilization rate is high.
Above description is to explanation of the present utility model, is not the restriction to utility model, and this utility model limited range is referring to claim, within protection domain of the present utility model, it is possible to do any type of amendment.
