Description of drawings
Fig. 1 is the utility model flue gas Teat pump boiler functional-block diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model flue gas Teat pump boiler is described in further detail.
As shown in Figure 1, the utility model flue gas Teat pump boiler, comprise air source hot pump water heater body 1 and evaporimeter 2, air-water heat exchanger 5, hybrid cooling device 6, water-water heat exchanger 10 and water tank 3, be connected with first flue 11 between the exhaust gases passes of air-water heat exchanger 5 and gas fired-boiler 4, be connected with second flue between air-water heat exchanger 5 and the hybrid cooling device 6, be connected with the 3rd flue between hybrid cooling device 6 and the evaporimeter 2, being provided with muffler 12 on the outlet pipe of evaporimeter 2 is connected with hybrid cooling device 6, be connected with circulating water pipe between water tank 3 and the air-water heat exchanger 5, on circulating water pipe, be provided with circulating pump 8, air-water heat exchanger 5, hybrid cooling device 6 and Teat pump boiler body 1 are connected with condensate pipe respectively, each condensate pipe is connected with water-water heat exchanger 10, water-water heat exchanger 10 is connected with the water pipe of the source water of heating, water-water heat exchanger 10 is connected with Teat pump boiler body 1 by water inlet pipe, on inlet pipeline, be provided with water pump 9, be connected with outlet pipe between air source hot pump water heater body 1 and the water tank 3.Wherein the import of first flue is the double feed inlet structure, is provided with nertralizer dispenser 7 in the 3rd flue.
After adopting technology of the present utility model, can reduce the heating cost of hot water by three links:
1. flue gas will be discharged big amount temperature at the condensed water more than 40 ℃ in the process of heat exchanger cooling, at first by water-water heat exchanger source water to be heated is heated to 22 ℃ from 15 ℃, and this link does not produce operating cost.
2. source to be heated water is heated to 42 ℃ through air source heat pump from 18 ℃, and according to the characteristic curve of air source hot pump water heater, the temperature difference of Inlet and outlet water is during less than 20 ℃, and its COP value is the highest.Therefore, this link will allow air source water heater in efficient district's work, and its COP can reach 5-6,20 ℃ of need of water heating temperature rise per ton, 5 degree electricity, and cost is about 5.00 yuan.Because the operating load peak of winter heating boiler is generally at night, so air source hot pump water heater also can enjoy the policy of paddy electricity in the operation at night, and another has reduced and heats the water cost, also can play the effect of peak load regulation network simultaneously.If calculate, has only 0.5 yuan at one ton of water power consumption of this link heating, 5 its costs of degree according to 0.3 yuan of Beijing low ebb electricity/degree.
3. the hot water that has been heated to 40 ℃ further is heated to 60 ℃ through the air-water heat exchanger of high-temperature flue gas reuse part again, because flue-gas temperature 120 ℃ (steam oven is 150 ℃) is bigger with the temperature difference of heated water, so heat exchange efficiency is also very high.This link does not have operating cost (power of circulating pump is low can be ignored) yet.
4. owing to efficient heat exchange by above-mentioned three links, the combustion of natural gas fume afterheat (can be comprised sensible heat and latent heat, wherein latent heat accounts for more than 10% of Lowlevel thermal energy) all be used, if according to low heat valve is that benchmark calculates, the integrated heat efficiency that can make gas fired-boiler add present technique reaches more than 110%, produces well energy-conservation effect.
The overwhelming majority is a hydrocarbon in the composition of natural gas, burning back produce a large amount of water and gasification for steam (account for flue gas total measurement (volume) 20%) with fume emission in atmosphere.Can produce 1.55 kilograms steam after the burning of each cubic metre natural gas.The steam of exhaust temperature in the flue gas more than 120 ℃ is in superheat state.Because the condensation temperature of steam is about 58 ℃, existing flue gas recovery technology drops to 70-90 ℃ with flue gas, also can only reclaim the small part condensed water.Because the application of present technique, the flue gas of gas fired-boiler utilizes through three coolings, and final exhaust temperature is reduced near outside air temperature, then reclaims condensed water in reuse heat energy to greatest extent.With one 4 tons gas and hot water heating furnace gauges, move 20 hours every day, per hour consume gas 320M
3, 6400M need burn every day
3Natural gas.Can reclaim 10 tons/day of condensed waters in its discharged flue gas.The 2008 Beijing city consumes natural gas 5,200,000,000 M altogether
3If, its flue gas condensing water of 50% is reclaimed, can reach 4,000,000 tons of water, the water yield of a suitable small reservoir.
Owing in three temperature-fall periods, produce a large amount of condensed waters, the most of CO in the flue gas
2, NO
XCan be dissolved in the condensed water Deng pernicious gas and make it be faintly acid.So just reduced the pernicious gas that gas fired-boiler discharges in atmosphere, produced certain environmental benefit, contributed for further purifying Pekinese's air in the winter time.
Below be the analysis of techno-economic benefits:
The cost of present situation hot water is (it is 40 ℃ that one ton of water is heated to 55 ℃ of temperature rises from 15 ℃) relatively

| Gas heater | Natural gas | 8400Kcal/m 3 | 80％ | 5.95m 3 | 2.05 unit/m 3(civilian) 2.55 yuan/m 3(commercialization) | 12.20 15.17 yuan in unit |
| Oil burning boiler | Light diesel fuel | 10200Kcal/kg | 85％ | 4.61kg | 5.7 unit/kg | 26.28 unit |
With certain sub-district is example:
Heating boiler is six four tons of gas-fired water heating boilers, wherein five winter operation heating, and a whole year operation is specialized in the domestic hot-water.The present situation domestic water is 30-40 ton every day.According to the reality measuring and calculating, because water consumption is less, the boiler operatiopn management cost is very high, and the cost of present water heating per ton is 35.06 yuan.
As adopt the heat pump scheme, adopting the heating cost of heat pump in three seasons of spring and summer autumn is 6.686 yuan.Adopt winter flue gas to reclaim with heat pump united, utilize the low ebb electricity price again, water heating cost per ton can further reduce.5 yuan of annual hot water heating cost average out to.Than reducing 30 yuan with the gas fired-boiler heating at present, economic benefit is very tangible.
Investment estimate: according to measuring and calculating, the air source hot pump water heater investment is 10,000 yuan of/ton water/days, needs 400,000 yuan, and air-water heat exchanger, hybrid cooling device, 50 tons of water tanks etc. need 230,000 yuan, amount to 630,000 yuan of investments.According to 30 yuan of the 40 tons of saving per ton of supplying water day, annual operation 350 days can be saved 420,000 yuan, recoverable investment within a year and a half altogether.
