Description
Technical field：
The present invention relates to heat supply process field, specially a kind of Two-way Cycle hot-water boiler heating system.
Background technology
As the atmosphere pollution increasingly serious, energy is increasingly deficient, high pollution, high energy consumption enterprise must carry out energy-saving and emission-reduction.
The coal type fuel of heating boiler has been altered in steps as oil, gas type fuel.In oil, gas type fuel combustion, on the one hand, due to combustion
Contain a large amount of protiums in material, from air flue emission to external environment in the water vapour produced that burns, water vapour has considerable change
Heat is by serious waste；On the other hand, the high-temperature flue gas in boiler is emitted into the wave that external environment also results in a part of heat
Take.Therefore, if the water vapour in above-mentioned high-temperature flue gas and flue gas is effectively reclaimed, the thermal efficiency of boiler can be greatly improved.
In building and heating, boiler combustion fuel carrys out heat cycles water and used for warmer, wherein the backwater temperature of warmer
Degree is generally 70 DEG C (specified return water temperature of boiler), in order to improve the thermal efficiency of boiler, if by the backwater and high temperature of warmer
Vapor in flue gas and flue gas carries out heat exchange, and because the return water temperature of warmer is higher, two media is in heating surface
Mean temperature difference it is small, cause the heat recovery rate of vapor in high-temperature flue gas and flue gas extremely low, it is difficult to improve the thermal effect of boiler
Rate.
The content of the invention
It is an object of the invention to provide a kind of Two-way Cycle hot-water boiler heating system, the high temperature cigarette of boiler generation is greatly improved
The heat recovery rate of vapor in gas and flue gas, improves the thermal efficiency of boiler.
To achieve these goals, the technical scheme used for：A kind of Two-way Cycle hot-water boiler heating system, passes through boiler
Recirculated water after body heating enters warmer by the first outlet pipe, and the recirculated water after being exchanged heat with warmer passes through the first backwater
Pipeline enters in boiler body；The smoke evacuation end of boiler body is connected with heat exchange unit, the recirculated water after being heated by heat exchange unit
Enter floor heating device by the second outlet pipe, the recirculated water after being exchanged heat with floor heating device enters heat exchange unit through water return pipeline.
Compared with prior art, technique effect of the invention is：Recirculated water after heat exchange unit is heated goes out by second
Water pipe enters floor heating device, and due to about 40~50 DEG C of the supply water temperature of floor heating requirement, and return water temperature only has 30 DEG C or so,
Mean temperature difference of the vapor in whole heating surface is big in the backwater and high-temperature flue gas and flue gas of floor heating device, therefore, boiler
The heat recovery rate of vapor is high in the high-temperature flue gas and flue gas of generation, and the thermal efficiency of boiler greatly improved.
Brief description of the drawings
Fig. 1 is the schematic diagram of Two-way Cycle hot-water boiler.
Embodiment
The present invention is described in further detail with reference to Fig. 1.
A kind of Two-way Cycle hot-water boiler heating system, the recirculated water after being heated by boiler body 10 passes through the first outlet pipe
21 enter warmer 20, and the recirculated water after being exchanged heat with warmer 20 is entered in boiler body 10 by the first water return pipeline 22；
The smoke evacuation end of boiler body 10 is connected with heat exchange unit 30, and the recirculated water after being heated by heat exchange unit 30 passes through the
Two outlet pipes 31 enter floor heating device 40, and the recirculated water after being exchanged heat with floor heating device 40 enters heat exchange unit through water return pipeline 32
30。
In such scheme, the water circulation flow of boiler is divided into two single circulation loops, and main circulation loop is：Warmer
20 → the first 22 → boiler body of water return pipeline, 10 → water outlets → warmer 20, this loop makes for the user of the heating of warmer 20
With；Auxiliary circulation loop is：32 → heat exchange unit of water return pipeline, the 30 → water outlet of floor heating device 40 → the second → floor heating device 40, this time
Road is used for the user of the heating of floor heating device 40.
Recirculated water after heat exchange unit 30 is heated enters floor heating device 40 by the second outlet pipe 31, due to floor heating
It is required that about 40~50 DEG C of supply water temperature, and return water temperature only has 30 DEG C or so, the backwater and high-temperature flue gas of floor heating device 40 with
And mean temperature difference of the vapor in whole heating surface is big in flue gas, therefore, high-temperature flue gas and flue gas reclaimed water that boiler is produced
The heat recovery rate of steam is high, and the thermal efficiency of boiler greatly improved.
The heat exchange unit 30 is two condensers 34 being adjacently positioned on smoke evacuation direction.Ensure that heat exchange unit 30 can be high
The heat of vapor in high-temperature flue gas and flue gas is reclaimed on effect ground.
First water return pipeline 22 is connected with first pump housing 23, and recirculated water is pumped into boiler body 10 by first pump housing 23.Make
Recirculated water being capable of efficient circulation in main circulation loop, it is ensured that warmer 20 is able to maintain that constant heating temperature.
Second water return pipeline 32 is connected with second pump housing 33, and recirculated water is pumped into heat exchange unit 30 by second pump housing 33.Make
Recirculated water in auxiliary circulation loop can efficient circulation, on the one hand ensure that floor heating device 40 is able to maintain that constant heating temperature；
On the other hand keep return water temperature stable with the high-temperature flue gas temperature difference, so that it is guaranteed that high-temperature flue gas and flue gas reclaimed water that boiler is produced
The heat recovery rate of steam.
