Description
[technical field]
The utility model relates to waste-heat recovery device, is specifically related to a kind of multistage plate evaporation absorption type refrigerating unit.
[background technology]
Traditional absorption-type refrigerating method has had the production history of last 100 years, adopts the thermodynamic process and equipment that finalize the design almost; In actual use, with the most use be for the Lithium Bromide Absorption Refrigeration Cycle of air-conditioning with for freezing, the ammonia absorption type kind of refrigeration cycle of air-conditioning.The impact of nearly decades owing to specifying by " Montreal Agreement ", reduce the use of fluorine carbide, and the meaning utilizing waste heat to have minimizing carbon emission as driving heat source, absorption-type refrigerating method obtains larger popularization and development, such as, in Chinese patent CN200510060377.7 " lithium bromide refrigerating air conditioner that multiple-energy-source drives " patent, make use of solar energy, microwave and fuel oil (gas) various energy resources, Japan Patent 2009-236440 " Gasheatpuptypeairconditioningdeviceorrefrigeratingdevice " and 2009-236441 " Heatpuptyperefrigeratingdevice " develops with gas engine used heat as air-conditioning, the absorption-type refrigerating method of refrigeration machine thermal source.This kind of refrigerating method is applied to the utilization of low temperature exhaust heat more.But these improve the Energy Efficiency Ratio that all can not improve Absorption Cooling System itself.Determine that the COP of double-effect lithium bromide absorption type unit is 1.12 ~ 1.4 in up-to-date GB29540-2013 " lithium bromide adsorption water chilling unit energy efficiency market and efficiency grade " standard, and the input heat source stream of double-effect lithium bromide refrigeration machine is 150 DEG C of even higher temperatures, and ammonia-cold COP of water absorption type unit is only 0.3 ~ 0.4.Because steam mechanical compressing hot pump has the sensible heat that can promote low temperature exhaust heat steam by very little mechanical power, become high-temperature steam just its latent heat recyclable, utilize as high temperature heat source, therefore come into one's own in heat energy system, at Chinese patent CN201010198705.0 " by pump for extracting power plant waste heat heating-condensing water system "; Chinese patent CN20101063699.5 " cogeneration of heat and power coupling heat pump feasible region cold-hot combined supply system and method "; Chinese patent CN200910223748.7 " low-temperature waste heat power generation system exhaust steam condensation process self-coupling cold source heat pump circulating device "; Chinese patent CN201010163688.7 " central heating system of coupling circulating water heat pump of power plant with cogeneration and method " relate to and utilizes low-temperature heat source, comprise water and steam, improved the Energy Efficiency Ratio of the power generation and heat supply system of whole cogeneration of heat and power by source pump; But all do not relate to and utilize steam mechanical compressing hot pump to be applied to problem in refrigeration, Air-conditioning Cycle, to improve the Energy Efficiency Ratio problem of refrigeration unit itself.
The wherein fundamental cause that the Energy Efficiency Ratio of absorption-type refrigerating method is low is that the refrigerant vapour that heat absorption generates when high pressure generator water as refrigerant carries out concentrated needs to absorb a large amount of heat energy, and the heat contained by refrigerant vapour discharges the heat of transformation and is discharged into outside system in condensation process, can not get recycling; And cold-producing medium absorbs the low temperature heat energy of refrigerant circulation water and then generates low-temp low-pressure refrigerant vapour in low pressure evaporator, this refrigerant vapour enters absorber has again vapour phase to change liquid phase into, the heat that phase transformation discharges, is usually also discharged into outside refrigeration system, is not also recycled utilization.In CN201020188184.6 " dual-effect type-II lithium bromide absorption heat pump unit ", just develop a kind of source pump of heat supply, do not solve in above-mentioned circulation the reuse of discharging heat.At CN200820115165.3 " single-effect type third-kind absorption heat pump that a kind of cold and hot two-way simultaneous utilizes ", because make use of the discharge heat of a part, for heat supply, can supply cold-peace heat supply, COP can reach 2.2 ~ 2.6 simultaneously.But because be not be again back to system, reduce and drive the input of refrigeration system energy, so the reuse problem of discharge heat fundamentally can not be solved.The problem of low-energy-efficiency ratio is not solved, therefore the Energy Efficiency Ratio of refrigeration and heating yet, still all very low.
Absorption refrigeration, the major reason that Air-conditioning Cycle cost is high is, many employing pipe shell type heat exchange equipment and spray mass transfer method traditionally, heat transfer, mass tranfer coefficient is low, heat exchange area is large, also need circulating pump, spray-absorption solution and cold-producing medium repeatedly, and at Chinese patent CN200480010361.9 " the band absorber of external circuit and heat exchanger and comprise heat pump and the air-conditioning system of this absorber or heat exchanger " with plate type heat exchanger as absorber or condenser, to improve heat exchange efficiency, comprise US Patent No. 6176101B1 " FLAT-PLATEABSORBERSANDEVAPORATORSFORABSORPTIONCOOLERS " then condenser and absorber to be assembled in a plate type heat exchanger, this equipment is that recovering condensing heat provides possibility, but this patent does not propose solution for the Energy Efficiency Ratio solving absorption-type refrigerating method improves and reduce system cost.
