Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, a kind of central heating regulating system of the utility model, comprises, steam turbine 12, steam water heat exchanger 1, source pump 11 and heat exchange station; The steam of steam turbine 12 enters source pump 11 and steam water heat exchanger 1, heat exchange station inside is connected with phase-transition heat-storage system 7, form new heat exchange station system, this heat exchange station system primarily of heat transmission equipment 3, phase-change heat accumulation system 7, the compositions such as water circulating pump, by-pass valve control, temperature flow monitoring form 8; Wherein, phase-change heat accumulation system is made up of efficient phase-change material and energy storage panel.
One secondary net water supply line is connected with phase-transition heat-storage system 7 by by-pass line, and on by-pass line, be provided with a secondary net water supply by-pass governing valve 9, after phase-transition heat-storage system 7, get back to a secondary net water return pipeline by by-pass line; One secondary net water supply line is connected on the pipeline of heat transmission equipment 3, and is provided with a secondary net water supply control valve door 2 in the rear end of this by-pass line; Through a secondary net water of vapor-water heat exchanger, by regulating the aperture of a secondary net water supply control valve door 2 and a secondary net water supply by-pass governing valve 9, control the flow once supplying net water that a secondary net water supply enters heat transmission equipment 3 and phase-change accumulation energy system 7 respectively, the secondary net water supply entering heat transmission equipment 3 provides heat and enters a secondary net water return pipeline by a secondary net water circulating pump 10 after cooling in heat transmission equipment 3, and the secondary net water supply energy storage in energy-storage system entering phase-change accumulation energy system 7 enters a secondary net water return pipeline by a secondary net water circulating pump 10 after also lowering the temperature.Secondary network water return pipeline is connected with phase-transition heat-storage system 7 by by-pass line, and secondary network backwater by-pass governing valve 5 is installed on the by-pass line of secondary network water return pipeline to phase-transition heat-storage system 7, and in the rear end of this by-pass line, secondary network backwater control valve 6 is installed, by regulating the aperture of secondary network backwater control valve 6 and secondary network backwater by-pass governing valve 5, control the flow that secondary network backwater enters the secondary network backwater of heat transmission equipment 3 and phase-change accumulation energy system 7 respectively, the secondary network backwater entering heat transmission equipment 3 absorbs heat and enters secondary network water supply line by secondary network water circulating pump 4 after intensification in heat transmission equipment 3, the secondary net water entering phase-change accumulation energy system 7 absorbs heat and enters secondary network water supply line by secondary network water circulating pump 4 after intensification in energy-storage system.It is worthy of note and on water return pipeline, temperature and flow monitoring table 8 are all installed at a secondary net and secondary network, according to the temperature of monitoring, flow is in conjunction with outdoor temperature and regulation and control instruction, regulate the aperture size of aperture for backwater reverse side and bypath valve, the supply and return water temperature flow of monitoring form monitoring with a certain accidental conditions for calibration point.
In central heating system stable operation process, a secondary net supply backwater temperature difference is 40 DEG C, and secondary network supply backwater temperature difference is 20 DEG C.General, a secondary net supply water temperature is 70 DEG C ~ 90 DEG C, secondary network supply water temperature 50 DEG C ~ 60 DEG C, concrete condition according to cold at the beginning of different geographical winter, severe cold, end is cold has nothing in common with each other.In concrete heat supplying process, some day, outdoor temperature was constantly change, thus, in order to realize the object of energy saving in heating system, heat supply initial station needs according to the change (can divide 3 or 4 periods for general a day) of outdoor temperature, also constantly can adjust initial station one secondary net supply water temperature or enter a secondary net flow of heat exchange station.Such adjustment, although can realize energy-conservation object, does not make energy-conservationly to realize maximum, there is system response slow simultaneously, and response phenomenon not in time, can not meet user side demand, and the requirement of user side response, heating demand regulates not ideal enough.This method is embodied as, when outdoor temperature promotes, when user's thermic load reduces, turn down a secondary net water supply control valve door 2, open a large secondary net water supply by-pass governing valve 9, make a net height warm water flow into the energy storage of phase-change heat accumulation system release heat in certain proportion, then get back to a secondary net water return pipeline.When outdoor temperature reduces, open large secondary network backwater by-pass governing valve 5, turn down secondary network backwater control valve 6, close a secondary net water supply by-pass governing valve 9, open a large secondary net water supply control valve door 2, make secondary network backwater flow into phase-change heat accumulation system in certain proportion and absorb heat, then feed to user with secondary network water supply mixing.Do like this and not only fully improve system energy efficiency, and for user side demand, can respond in time.Meanwhile, for the heating system being source pump with thermal source station, unnecessary heat in a secondary net water is stored in phase-change heat accumulation system 7 and can ensures rational return water temperature, be conducive to elevator system COP.For cogeneration of heat and power, thermic load peak regulation is done by phase-change accumulation energy system, can effectively assist completion system peak regulation adjust paddy, concrete mode: institute's steam pumping directly enters after vapor-water heat exchanger 1 heats a net water and gets back to boiler, the calorific requirement of user within certain period determine power plant's steam pumping amount number.When outdoor temperature reduces, user's calorific requirement increases, and steam pumping amount increases, and outdoor temperature raises, and user's calorific requirement reduces, and corresponding steam pumping amount reduces.But, the number of steam pumping amount, paddy can be adjusted to produce favourable or adverse influence to peak regulation of power plant, thus the present invention increases phase-transition heat-storage system 7, to reduce adverse effect, the electricity consumption period is probably divided into: peak value: when morning 7 to 11 time, when evening 17 to 22 time, valley: when evening 23 to next day morning 5 time, all the other periods are level values.When daytime temperature is high time, with level periods or paddy period, unnecessary heat stores up phase-transition heat-storage body, for evening 17 time use to 22 periods heating, at this moment do not need extra increase steam pumping amount to meet the hot requirement of user, do not affect the generated energy of power plant's peak period simultaneously, enter and both ensure that generated energy income, also ensure that user's heat amount yet.
Operation principle of the present utility model is: a secondary net feed pipe enter heat exchanger end open bypass enter phase-change accumulation energy system after release heat return a secondary net water return pipeline.When thermic load reduces, one time mesh portions high-temperature water enters phase-change accumulation energy system through by-pass line, gets back to a secondary net water return pipeline, complete energy storage after releasing energy.Secondary network water return pipeline bypass gets back to secondary network water supply line after entering phase-change accumulation energy Systemic absorption heat.When thermic load promotes, secondary network part backwater enters phase-change accumulation energy system through by-pass line, enters secondary network water supply line after absorbing heat.
