Summary of the invention
In view of the defect that prior art exists, the present invention will provide a kind of diesel generating set waste heat recovering energy conserving system, and the heat recovery of utilization smoke evacuation heat exchanger realizes the object of heating.
In order to realize above-mentioned improving eyesight, the technical solution adopted in the present invention is: diesel generating set waste heat recovering energy conserving system, is characterized in that: comprise diesel generating set, smoke evacuation heat exchanger, heat pump, heating unit, water storage box, unit heat exchanger, heat supply network water pipe, heat supply network return pipe, waste heat return pipe, supplement water pipe, diesel generating set is connected with smoke evacuation heat exchanger one end by pipeline, from smoke evacuation heat exchanger, draw another pipeline and connect heat pump one end, at the heat pump the other end, be also provided with heat supply network water pipe, heat supply network water pipe is connected to one end, heating unit, the heating unit the other end is also provided with waste heat return pipe and is attached thereto, the waste heat return pipe the other end is connected with water storage box, from the water storage box the other end, drawing equally waste heat return pipe is connected in unit heat exchanger, simultaneously, on unit heat exchanger, be also provided with two pipelines, wherein pipeline and diesel generating set form closed circulation, another pipeline is linked back on smoke evacuation heat exchanger, on described water storage box, be also provided with supplementary water pipe.
540 ° of C of diesel generator high-temperature smoke discharging waste gas discharge from diesel generating set, enter smoke evacuation heat exchanger, along touring pipeline, the water outside pipe is heated, the aqueous medium of smoke pipe outside is heated to after 90 ° of C by 75 ° of C, by heat pump, deliver to heating unit, 50-55 ° of C lowers the temperature, aqueous medium after cooling enters water storage box, by water storage box, get back to unit heat exchanger again, at this moment water temperature lower (40-50 ° of C), the generator of flowing through, carries out systemic circulation cooling, 150-250 ° of C to the generator of work high temperature; In the process to generator cooling, water is heated again, the aqueous medium of temperature increase to 90 ° more than C is transported to the place that needs heat supply heating again, the waste gas that reclaims waste gas by smoke evacuation heat exchanger in system by 540 ° of C coolings after waste gas in pipe be drained after cooling, the exhaust gas temperature being discharged from is 120-140 ° of C, new high-temperature smoke discharging waste gas enters again smoke evacuation heat exchanger, and so continuous flue gas water of radiation heating, reaches and recycle object.
describedwater in heat supply network return pipe first passes through the preheating of unit heat exchanger, and then through smoke evacuation heat exchanger, heat exchange heats up, and by heat pump and heat supply network water pipe, externally confesses.
describedthe water of waste heat return pipe is introduced into water storage box, after mixing, returns to thermal source again by waste heat return pipe with supplementing water, enters systemic circulation.
For the water output in moment assurance system, if water storage box in use aqueous medium produce loss, system can be supplemented the needed water yield automatically, if lossless, maintains the water of former water storage box.
Compared with prior art there is following beneficial effect: due to the application of diesel generator waste heat recovering energy conserving system technology, can improve energy profit efficiency, by smoke evacuation heat exchanger, reclaim heat, conversion is to aqueous medium, by temperature increase to 90, the aqueous medium ° more than C is transported to the place that needs heating again, and diesel generating set often provides the electric power of 100kW, and the using waste heat from tail gas of discharge can meet the heating demand of 2500 square metres, both energy-conserving and environment-protective, can bring huge economic benefit again.
