Description
Technical field
The utility model belongs to energy supply system, particularly a kind of distributed energy supply station that utilizes marsh gas power generation to combine with heat pump techniques.
Background technique
In prior art, about marsh gas power generation and heat pump techniques, be summarized as follows.
1, biogas power generation technology mainly comprises biogas fermentation and generating two-part.
The definition of biogas fermentation is: biogas fermentation, claim again anaerobic fermentation or anaerobic digestion, refer to organic substance (as crop straw, weeds, human and animal excreta, rubbish, mud and city domestic sewage and industrial organic waste water etc.) under anaerobic, by the catabolism of of a great variety, enormous amount, each quasi-microorganism that function is different, finally produce the process of biogas.
Biogas combustion generating is the biogas utilization technology occurring along with the development of large methane tank construction and biogas comprehensive utilization, and it is processed by anaerobic fermentation the biogas producing and is used for motor, and composite generating set is housed, to produce electric energy and heat energy.Marsh gas power generation has the features such as wound effect, energy-conservation, safety and environmental protection, is a kind of widely distributed and inexpensive distributed energy.
Marsh gas power generation is in widespread attention and positive popularization in developed country.Biomass power generation is grid-connected, and in West Europe, some countries account for 10% left and right of energy total amount.
Biogas power generation technology is to integrate environmental protection and energy-conservation comprehensive utilization of energy new technology.It is a large amount of organic wastes (such as wine lees liquor, manure of livestock and poultry, municipal waste and sewage etc.) that utilize in industry, agricultural or urban life, through anaerobic fermentation, process the biogas producing, the generating of driving Biogas Generator Set, and can fully the waste heat of generator set be used for to biogas production.
The thermal efficiency of marsh gas power generation Cogeneration Project, has larger difference depending on the difference of power generating equipment, as used gas internal-combustion engine, its thermal efficiency is between 70% ~ 75%, and as used combustion gas turbine and exhaust heat boiler, the in the situation that of afterburning, the thermal efficiency can reach more than 90%.

Process one: the extraction of waste heat heat.
In the heat-exchanger of vacuum, utilize the water principle that boiling point reduces under negative pressure state, steam condensation water from reheater sprays the outer surface low-temperature evaporation at heat-exchanger heat exchanging tube, the heat of the low temperature exhaust heat of solidifying water absorption heat-exchange pipe internal flow, carburation by evaporation produces steam and enters both sides heater, completes the leaching process of waste heat heat.
Process two: the transfer of waste heat heat.
In heater, utilize the water suction exothermicity of bromize lithium concentrated solution, bromize lithium concentrated solution from concentrator is distributed in heater heat exchanging tube outside, absorption is from the water vapor of heat-exchanger, and the temperature of solution raises rapidly, needs to improve the heating agent of temperature in heating heat exchanging tube, the heat of having realized low-temperature heat source shifts to being heated heating agent, lithium-bromide solution, by dense thinning, no longer has moisture absorption simultaneously, after needing to concentrate, recycles.
Process three: working medium is concentrated.
In concentrator, utilize the heat of driving heat source, the bromize lithium dilute solution from heater is concentrated, the concentrated solution of generation continues to get back to continuation in heater and absorbs steam heating supplying hot water, and the concentrated high temperature secondary steam producing of solution removes reheater.
Process four: secondary steam heats again.
In reheater, utilization is from the heat of the high temperature secondary steam condensation latent heat of concentrator, the heating agent through once heating from heater is heated again, finally reach our temperature required heating agent, steam condensation becomes solidifying water and is transported to vaporizer and proceeds circulating and evaporating.
According to statistics in 1997, China's power plant thermal efficiency is 32.95%, power plant's heating efficiency is 83.68%, energy conversion total efficiency be 38.07%. adopt thermoelectric cold triple supply system or claim supply system (TES---TotalEnergySystem), after gas-fired heat pump (GEHP), the utility scale analytic explanation of Thermal Efficiency Analysis and the second law of thermodynamics by the first law of thermodynamics: owing to utilizing used heat, the comprehensive utilization of GEHP can reach 80%-85%; If by axle power transmission heat pump, utilized Lowlevel thermal energy, therefore integrated heat efficiency can reach 150%-170%. for TES mode, realize after thermoelectric cold triple supply, its comprehensive utilization ratio can reach the 39 current techique of thermoelectric cold cogeneration technology being listed in to national encourage growth of 65%-80%. < < Energy Conservation Law of the People's Republic of China > >, has promoted the development of heat pump cause.
3, distributed energy is a kind of energy supply mode of building user side in, can independent operating, also can be incorporated into the power networks, to maximize with resource, environmental benefit the system of determining mode and capacity, by user's various energy resources demand, and status of resource allocation carries out system combination optimization, the novel energy system of the design of employing demand reply formula and modular arrangements, is the distributing energy-provision way with respect to central energy supply.
Large-scale agricultural planting base and the pastoral farming cultivation base in rural area, around built, will produce a large amount of agriculture and forestry organic waste material and livestock poultry dung every year, if be not used, can not pollute surrounding enviroment.The at present domestic technology of biomass resource generating of utilizing reaches its maturity, mainly comprises Biomass Gasification Power Generation Technology and biomass-making natural pond generation technology.In above-mentioned agricultural planting base and pastoral farming cultivation base periphery build small-sized biomass power station, utilize internal combustion engine generator group directly to periphery resident, to power; The steam heating circulating water that the high-temp waste gas that internal-combustion engine is discharged produces by heating exhaust heat boiler, can be in the winter time to periphery resident heat supply, summer by heat pump techniques to resident's cooling; Unnecessary Straw Gas or biogas can be cooked for resident is daily.
