Description
Technical field
The exhaust steam residual heat that the utility model belongs to based on absorption heat exchange reclaims cogeneration of heat and power field, the direct recovery method of exhaust steam and the device of the absorption heat recovery of particularly a kind of water-cooled thermoelectricity plant.
Background technique
The main system form of north China heating at present is: cogeneration of heat and power, district boiler room and dispersion heating respectively account for about 1/3; Wherein the primary energy utilization ratio is the highest, emission reduction effect is best, the most rational the applying of cogeneration of heat and power of Economy receives the restriction that is difficult to expand on a large scale factors such as heat supply network scale and heat capacity thereof, needs badly and takes better technology path and policy planning to promote.Carry out exhaust steam residual heat based on absorption heat exchange and reclaim with the related patent U.S. Patent No. of great temperature difference heat supply technological by what Tsing-Hua University building energy conservation research center was creatively developed; Can be implemented in thermoelectricity plant adopts absorption heat pump recovery exhaust steam in steam turbine waste heat to be used for central heat supply; Can make thermoelectricity plant's efficiency of energy utilization improve 15～25%, and significantly enlarge its heat capacity.This technology has been applied to engineering practice and has obtained good effects of energy saving and emission reduction and economic benefit.
The mode that adopts absorption heat pump to realize that exhaust steam residual heat reclaims comprises the direct recovery of exhaust steam and reclaims two kinds indirectly; Fig. 1 is the water-cooled co-generation unit structure principle chart of the indirect way of recycling of exhaust steam residual heat of routine, and this system mainly is made up of water-cooled vapour condenser 1, original exhaust steam connecting tube 2, steam turbine 6, generator 7, absorption heat pump 9, water-cooled cooling tower 10 and cooling water cycle water pump 11; Wherein, generator 7 links to each other with steam turbine 6, and steam turbine 6 links to each other with water-cooled vapour condenser 1 through exhaust steam connecting tube 2, links to each other with absorption heat pump 9 through pipeline; Absorption heat pump 9 constitutes circulation loops with water-cooled vapour condenser 1 and cooling water cycle water pump 11, water-cooled vapour condenser 1 also with water-cooled cooling tower 10 and cooling water cycle water pump 11 formation loops.The indirect way of recycling of this waste heat is: the vaporizer that is fed to absorption heat pump 9 by the cooling circulating water of water-cooled vapour condenser 1 heating carries out heat release; And by absorption heat pump 9 its transfer of heat is used to once netting in the backwater, so exhaust steam residual heat is recovered utilization indirectly through cooling circulating water.
Another kind is the water-cooled co-generation unit mode of the direct way of recycling of exhaust steam; Different is with Fig. 1; In the direct way of recycling of this waste heat; The vaporizer that steam turbine 6 exhaust steam are directly sent into absorption heat pump 9 through exhaust steam connecting tube 2 carries out heat release, and by absorption heat pump 9 its transfer of heat is used to once netting in the backwater.But the vapour condenser of this exhaust steam in steam turbine cooling system is to adopt air cooling island mode, because it has long circular fairlead usually, is convenient to be provided with electric butterfly valve and carries out exhaust steam assignment of traffic and control, therefore can realize adopting the direct way of recycling of this exhaust steam.But for the water-cooled co-generation unit of the employing water-cooled vapour condenser of routine, then owing to there is not this pipe deriving structure, and site space is comparatively compact usually, possibly adopt usual way directly to draw exhaust steam hardly.
Both comparatively speaking, the latter sends into absorption heat pump by cooling water again and carries out heat recovery owing to need at first exhaust steam residual heat to be transferred in the cooling water; Consequently lost 10～15 ℃ heat transfer temperature difference; This will bring following adverse effect: cause the evaporating temperature of absorption heat pump to decline to a great extent, cause the heating capacity of same heat pump main frame to descend, heating efficiency descends; Heatedly once net the temperature rise of backwater in heat pump and significantly reduce; Add exhaust steam residual heat proportion decline in the heat, the ratio that is recovered utilization in the exhaust steam total amount descends, and absorbs the needed main machinery console number of same exhaust steam amount and greatly increases; The initial cost and the significantly increase that takes up room; Energy-saving benefit and economic well-being of workers and staff decline to a great extent, and the modification scheme PRACTICE OF DESIGN of many actual thermoelectricity plants co-generation unit proves that the exhaust steam yield and the energy-saving benefit thereof of this dual mode can differ more than 2 times.Therefore; Under possible situation, should preferentially select for use exhaust steam directly to get into absorption heat pump carries out the mode of heat recovery but not reclaims the indirect way of recycling of preheating through cooling water, the mode that the steam turbine circulatory system that particularly adopts the air cooling island to carry out the exhaust steam condensation can only select exhaust steam directly to reclaim.
But; A large amount of co-generation units that cool off (comprising the direct current type of cooling and clammy mode) with newly-built employing water-cooled exhaust steam of having built; Owing to often be connected comparatively compactness between its steam turbine (low pressure (LP) cylinder) exhaust steam exhaust port and the water-cooled vapour condenser; And have more and adopt rectangular duct or other special-shaped pipeline but not circular pipe connects, therefore be difficult to offer the exhaust steam drawing-off mouth.And often also be difficult to be provided with or set up large-scale valve and be used to cut off or regulate the exhaust steam flow to satisfy the requirement that absorption heat pump reclaims exhaust steam residual heat.Thus, for the co-generation unit, particularly large scale system that adopt the water-cooled vapour condenser, almost can't realize directly drawing of exhaust steam, thereby have to adopt the mode of carrying out indirect heat recovery through cooling water.
Therefore, be necessary to seek exhaust steam residual heat recyclability, raising effects of energy saving and emission reduction and the Economy thereof of brand-new exhaust steam outbound course to improve absorption heat pump.
