The water-cooled steam turbine waste heat direct recovery system tandemly inducing exhaust steam to the heat pump is designed to solve difficulties that exhaust steam connection pipes between a steam exhaust port and a condenser of a water-cooled steam turbine are usually tight and how to induce the exhaust steam into an absorption heat pump to achieve high-efficiency waste heat recovery. According to the water-cooled steam turbine waste heat direct recovery system tandemly inducing exhaust steam to the heat pump, a closed partition is arranged on the lower portion of the inner of an original exhaust steam connection pipe, an upper side opening and a lower side opening of the partition are arranged on one side surface of the exhaust steam connection pipe, wherein the upper side opening is used for inducing the exhaust stream into an inlet of an evaporator of the absorption heat pump, and an outlet of the evaporator is connected with the lower side opening. The exhaust steam flows downwards into an exhaust steam inlet of the water-cooled condenser, accordingly, the absorption heat pump and the water-cooled condenser are in series connection in the condensing process of the exhaust steam, annual operation adjustment of a heating system and reliable condensing process of the exhaust steam can be conveniently achieved, and the operation efficiency and energy-saving economic benefits can be achieved to be higher than those in conventional indirect waste heat recovery by extracting waste heat from cooled water.
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, particularly the water-cooled turbine residual neat recovering system of the in-line introducing absorption heat pump of exhaust steam.
Background technology
The main system form of present Chinese northern area heating 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 steam power plant adopts absorption heat pump recovery exhaust steam in steam turbine waste heat to be used for central heating; Can make steam power 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 condenser 1, original exhaust steam tube connector 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 condenser 1 through exhaust steam tube connector 2, links to each other with absorption heat pump 9 through pipeline; Absorption heat pump 9 constitutes closed circuits with water-cooled condenser 1 and cooling water cycle water pump 11, water-cooled 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 evaporimeter that is fed to absorption heat pump 9 by the cooling circulating water of water-cooled 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 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 evaporimeter that steam turbine 6 exhaust steam are directly sent into absorption heat pump 9 through exhaust steam tube connector 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 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 water-cooled co-generation unit for the employing water-cooled 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, therefore can't implement direct way of recycling.
Both comparatively speaking, the former sends into absorption heat pump by cooling water again and carries out waste 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 engine bed 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 steam power 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 waste 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; Built co-generation unit at present in a large number with newly-built employing water-cooled exhaust steam cooling (comprising the direct current type of cooling and clammy mode); Owing to often be connected comparatively compactness between its steam turbine (low pressure (LP) cylinder) exhaust steam outlet and the water-cooled 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 outlet.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 condenser, almost can't realize directly drawing of exhaust steam, thereby have to adopt the mode of carrying out indirect waste heat recovery through cooling water.
Therefore, adopt the co-generation unit of water-cooled condenser to 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.
