Cold, heat and electricity triple supply distributed energy is generated electricity using natural gas as fuel by power plant, recycle its waste heat to Build cooling, heat supply.Due to realizing the step application of energy to natural gas, and distributed energy can be used for peak regulation, therefore Under the conditions of appropriate, using suitable management mode, energy utilization rate is can effectively improve, and the safety for improving network system can By property.But when combined supply system cannot be satisfied heat supply, the cooling needs of user, needs that complementary heating source is arranged, is for low-temperature receiver User's heat supply, cooling.The heat supply of combined supply system, cooling are integrated with the supplying heat source of supplement setting, for low-temperature receiver, so as to user Stabilization, controllable heat supply, cooling are exported, is the main target of technical staff.
Invention content
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of energy supplying system, it can be integrated not Same supplying heat source, the output energy supply for low-temperature receiver, and its output is controllable, adjustable.
Realizing a kind of technical solution of above-mentioned purpose is:A kind of energy supplying system, including heating system and cold supply system, it is described Heating system exports hot water to client terminal, and the cold supply system exports cold water to client;
The heating system includes a main supplying heat source and at least one secondary supplying heat source, and the main supplying heat source and the pair supply The output end of heat source, which is connected with each other, simultaneously to be connect by a water pipe with heat-exchange system, the heat-exchange system by feed pipe and The client terminal connection, the client terminal are connect with the main supplying heat source and the secondary supplying heat source respectively by return pipe; Water pipe is connect by shunting water pipe with the return pipe;
The cold supply system includes one main for low-temperature receiver and at least one secondary for low-temperature receiver, described main secondary to be supplied with described for low-temperature receiver The output end of low-temperature receiver, which is connected with each other, simultaneously to be connect by a water pipe with cold exchange system, the cold exchange system by feed pipe and Client terminal connection, the client terminal main are connect with the pair for low-temperature receiver by return pipe with described for low-temperature receiver respectively; Water pipe is connect by shunting water pipe with the return pipe.
Further, the main supplying heat source is the waste-heat oven of trilogy supply device.
Further, the secondary heat source is gas fired-boiler.
Further, it is described it is main for low-temperature receiver be trilogy supply device absorption chiller.
Further, the pair is electric centrifugal-type refrigerator for low-temperature receiver.
Further, the interconnecting piece of the shunting water pipe and a water pipe is equipped with butterfly valve.
The heat supply of different supplying heat sources is output in heat-exchange system by a kind of energy supplying system of the present invention, difference is for low-temperature receiver Cooling be output in cold exchange system can when heat supply, semen donors are more than or are insufficient for the demand of user into row buffering Secondary supplying heat source, pair are turned off or on accordingly for low-temperature receiver, then defeated to user terminal progress by heat-exchange system, cold exchange system Go out so that the output of energy supply is stable, controllable, adjustable.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of energy supplying system of the present invention.
Specific implementation mode
In order to preferably understand technical scheme of the present invention, below by specifically embodiment and in conjunction with attached drawing It is described in detail:
Referring to Fig. 1, a kind of energy supplying system of the present invention, which is the energy supply system combined with trilogy supply device System, including heating system and cold supply system, the main supplying heat source of heating system are the waste-heat oven 11 of trilogy supply device, secondary heat supply Source is two gas-fired water heating boilers 12 being arranged in parallel;Its cold supply system it is main for low-temperature receiver be trilogy supply device absorption refrigeration Device 21, pair are two electric centrifugal-type refrigerators 22 being arranged in parallel for low-temperature receiver.Heating system exports hot water to client terminal, Cold supply system exports cold water.
The output end of waste-heat oven 11 and gas-fired water heating boiler 12 is connected with each other and passes through a water pipe 31 and heat-exchange system Connection 41, heat-exchange system 41 is connect by feed pipe 32 with client terminal 5, client terminal 5 by return pipe 33 respectively with it is remaining Hot stove 11 and gas-fired water heating boiler 12 connect;Water pipe 31 is connect by shunting water pipe 34 with return pipe 33.
The output end of absorption chiller 21 and electric centrifugal-type refrigerator 22 be connected with each other and by water pipe 31 with Cold exchange system 42 connects, and cold exchange system 42 connect 5 with client terminal by feed pipe 32, and client terminal 5 passes through return pipe 33 connect with absorption chiller 21 and electric centrifugal-type refrigerator 22 respectively;Water pipe 31 is by shunting water pipe 34 and return water Pipe 33 connects.
The interconnecting piece for shunting water pipe and a water pipe is equipped with butterfly valve 6.
Under usual operating condition, energy supplying system passes through 21 cooling of absorption chiller by 11 heat supply of waste-heat oven.Heat supply Heat-exchange system 41 and cold exchange system 42 are carried out respectively with cooling to fill energy, then heat-exchange system 41 and cold exchange system 42 It is energized to user terminal 5.
By taking heating system as an example, when the heat supply of waste-heat oven 11 cannot meet the use demand of user terminal 5, according to heat supply Notch opens gas-fired water heating boiler 12 successively, and waste-heat oven 11 and gas-fired water heating boiler 12 are carried out to heat-exchange system 41 jointly at this time Energy is filled, and forms heat source that is uniform, stablizing in heat-exchange system 41, heat-exchange system 41 exports confession to user terminal 5 at this time Heat, and adjust the flow and hydraulic pressure of output.
When the heat supply of heating system has been more than the use demand of user terminal 5, butterfly valve 6 is first opened so that heat supply system The part heat supply of system enters return pipe 33 by shunting water pipe 34, without entering heat-exchange system 41, directly reduces heating load, so Close gas-fired water heating boiler 12 successively further according to heat demand afterwards.Heat-exchange system 41 still needs to adjust the flow and water of output at this time Pressure, to ensure to the output flow of user terminal 5 and the stabilization of hydraulic pressure.
Cold supply system is operated according to heating system.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention, And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above Change, modification will all be fallen within the scope of claims of the present invention.
