The fuel gas absorption heat pump smoke heat recovery unit greatly increases heat exchanging rate and smoke afterheat recovery rate through utilizing the heat pipes to exchange heat, which saves energy and increases efficiency.
Description
Technical field:
The utility model relates to a kind of auxiliary equipment of combustion gas class absorption heat pump, is specifically related to a kind of combustion gas class absorption heat pump flue gas heat-recovering device.
Background technology:
At present, generally about 130 ℃, exhaust gas volumn is very big for combustion gas class absorption heat pump discharged flue gas temperature, and flue gas is carrying a large amount of physics latent heat and the steam latent heat of vaporization.Such flue gas directly is discharged into great waste heat energy in the atmosphere, be unfavorable for the efficient operation of heat pump and energy-conservation, consider that heat in the low-temperature flue gas can use up many recovery, so set up flue gas heat-recovering device, the existing built-in smoke chamber of flue gas heat-recovering device hot water heat exchanger carries out heat exchange by both contacts area, because heat exchange area is limited, heat exchange mode is single, heat exchange efficiency is low, can not reclaim fume afterheat to greatest extent.
The utility model content:
The problem that the utility model is to overcome hot water heat exchanger in the background technology and the smoke chamber heat exchange area is little, heat exchange mode is single thereby can not the high efficiente callback fume afterheat, and provide a kind of combustion gas class absorption heat pump flue gas heat-recovering device, this flue gas heat-recovering device has improved rate of heat exchange and flue gas waste heat recovery rate greatly by utilizing heat pipe heat exchanging.
The invention for solving the technical problem can reach by following technical solution: this combustion gas class absorption heat pump flue gas heat-recovering device comprises hot water heat exchanger, the corresponding respectively outlet, inlet mouth that entery and delivery port is arranged and communicate of smoke chamber, upper and lower part, hot water heat exchanger both sides with smoke chamber; Smoke chamber and hot water heat exchanger are equipped with bearing between the bottom, and vertically run through the heat pipe that is filled with working medium in a plurality of on the smoke chamber top board.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: this combustion gas class absorption heat pump flue gas heat-recovering device is by utilizing heat pipe heat exchanging, because of heat pipe is a kind of thermal element with high thermal conductivity, be a kind of heat-transfer working medium by self inside in the closure casing of a high vacuum constantly circulating phase-change transmit the efficient element of heat, its heat transfer coefficient is the several times of common heat transfer type, heat transfer efficiency is high, therefore this heat exchange mode has increased heat exchange area and the heat exchange amount between hot water heat exchanger and smoke chamber, heat exchange efficiency and flue gas waste heat recovery rate have greatly been increased, energy efficiency.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure: 1-hot water heat exchanger, 2-water inlet, 3-smoke chamber, 4-gas outlet, 5-delivery port, 6-air inlet, 7-heat pipe, 8-bearing, 9-sewage draining exit.
The specific embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
As shown in Figure 1, this combustion gas class absorption heat pump flue gas heat-recovering device comprises hot water heat exchanger 1, smoke chamber 3, and hot water heat exchanger 1 one side upper and lower parts have water inlet 2, gas outlet 5 respectively, and the opposite side upper and lower part has delivery port 5, air inlet 6 respectively; The air inlet 6 of hot water heat exchanger 1 communicates with smoke chamber 3 respectively with gas outlet 4, is equipped with bearing 8 between smoke chamber 3 and hot water heat exchanger 1 bottom, and vertically runs through a plurality of heat pipes 7 on smoke chamber 3 top boards, is filled with working medium in the heat pipe 7.This flue gas heat-recovering device equipment directly is connected on the horizontal flue of absorption heat pump generator exhanst gas outlet, and the bottom that high-temperature flue gas is delivered to this device enters smoke chamber 3 by air inlet 6.Vertically run through a plurality of heat pipes 7 on the top board of smoke chamber 3, heat pipe is a kind of thermal element with high thermal conductivity, be a kind of heat-transfer working medium by self inside in the closure casing of a high vacuum constantly circulating phase-change transmit the efficient element of heat, its heat transfer coefficient is the several times of common heat transfer type, and heat transfer efficiency is high.Heat pipe be evaporimeter be again condenser, it is that a end from hot-fluid side draught heat is an evaporimeter, working medium absorbs carburation by evaporation behind the latent heat, flowing to cold fluid one end is condensation segment heat release liquefaction, and relies on the capillary force effect to flow back to evaporator section, finishes circulation automatically.Working medium in flue gas transversal flow heat pipe 7 bringing-up sections, make the bottom endotherm section of heat pipe absorb fume afterheat, the flue gas heat release makes the working-medium water that is in the heat pipe under the vacuum state or conduction oil heat absorption and vaporizes, boil-off is under differential pressure action, high velocity stream is to heat pipe top condensation segment, when entering hot water transversal flow heat pipe 7 condensation segments on hot water heat exchanger 1 top under by the water circulating pump effect, siphon away the latent heat that steam is emitted in the heat pipe and heated circulating hot water, at this moment the steam in heat pipe 7 condensation segments is condensed into liquid again, and this coagulating liq is in the dirty product heat cal rod of gravity effect 7 bottoms.Turn back to bringing-up section (fume side) circulation like this from condensation segment (circulating hot water side) and just constantly flue gas heat is sent to circulating hot water, finish the whole process that heat transmits.Utilize heat pipe to be fitted together by these single heat pipe collection exactly to flue gas heat exchange, to be dividing plate with the evaporator section of heat pipe 7 separate with condensation segment middle top board by smoke chamber 3 carries out heat exchange.Circulating hot water after the heating is sent in the absorption heat pump condenser by the delivery port 5 of hot water heat exchanger 1, and the flue gas after the heat exchange is sent into wet type desulfurizing device desulfurizing and purifying by gas outlet 4, and sewage draining exit 9 is used for blowdown.
This flue gas heat-recovering device need not external impetus and impels working fluid cycles, therefore fully absorbs fume afterheat and need not use additional energy source again, has greatly increased heat exchange efficiency and flue gas waste heat recovery rate, energy efficiency.
