Platform connects the heating system.
Heating system：
Energy resource structure refers to the composition and its ratio of all kinds of non-renewable energy in energy total growth or aggregate consumption, secondary energy sources
Relationship.The energy can be divided into high-grade energy and low-grade energy by quality, energy density.
Heating system low-grade energy can be met the requirements.Heat source is based on steam power plant, district boiler room at this stage, with
Supplemented by industrial exhaust heat, solar energy, wind/photoelectricity heating, underground heat, heat pump etc..
Hold over system：
The whole network distribution storage heating system can install regenerative apparatus in user side, pipe network side, heat source side, both meet heat source
Peak regulation needs, and has the characteristics that adjustable range reduces, away from closer to the user, flexibility is stronger, become solve load fluctuation and
For thermal retardation, realize on demand with the effective ways of heat.
The whole network distribution storage heating system is as shown in Figure 2 (open circles represent user, heat exchange station).May exist in system
Multiple heat sources, heat resource form can be the fossil fuels such as steam power plant, boiler room driving heat source, be also possible to wind-powered electricity generation heat,
The renewable energy heat source such as solar energy optical-thermal, soil source.User is both user in system, it is also possible to while providing source of sewage low product
Position thermal energy or other recyclable thermal energy, serve as small distributed heat source.
Accumulation of heat has water (liquid) accumulation of heat, phase-transition heat-storage, solid heat storage.Solid heat storage is mainly answered in terms of electric boiler storing up heat
There is corrosion and problem of aging with, phase-transition heat-storage, the two cost, technical difficulty are higher, and hot water regenerative apparatus simple structure, make
Valence is low, and safe and reliable, therefore the whole network distribution storage heating system recommendation uses the accumulation of heat of hot water heat-accumulator tank.
Hot water heat-accumulator tank is divided to gerotor type and two kinds of pressure-bearing type.When regenerator temperature is higher than 98 DEG C, generally stored using pressure-bearing type
Hot tank.It is rarely needed in central heating system since pressure-bearing heat-accumulator tank initial cost is high, safety is poor.It is most common in engineering
Accumulation of heat form is constant pressure storing heating, in order to avoid hot water evaporation, it is desirable that hot water temperature is no more than 98 DEG C.
The shape of heat-accumulator tank can be selected cylindrical and rectangular.
Consider from production run angle, cylindrical accumulator tank surface area is relatively small, consuming steel are few, radiating surface is small, is easy to
Arrangement, it is more practical.Cylindrical accumulator tank, the situation of surface area minimum are that length-width ratio (is highly 1 with diameter ratio H/D):1,
But consider that length-width ratio should be greater than 1.5 from operation, land occupation etc..
Adaptation to local conditions is answered in the selection of distributed heat-accumulator tank shape, small by occupied area, volume is big according to on-site actual situations
Rule determine.
Certain heat-insulation and heat-preservation is carried out outside accumulation of heat tank, and the heat dissipation capacity of tank body outwardly is reduced to minimum.Fig. 3
It show rough Temperature Distribution in the essential structure and tank body of heat-accumulator tank.
Accumulation of heat water pot internal reservoir hot water, water temperature is different, and the density of water is also different.In a sufficiently large container, by
In gravity, the different hot and cold water of density forms lamination of the hot water in upper, cold water under.Even if water is in flow regime
Under, as long as guaranteeing the control to reynolds number Re, the blending of hot and cold water in flowing is reduced as far as possible, it is possible to be had a common boundary in hot and cold water
One is formed at face has certain thickness temperature transition layer, i.e. mesolimnion.
When heat source quantity of heat production is greater than user's heat amount, accumulation of heat water pot enters heat storage state.Heat-accumulating process：High-temperature water via
Top water distributing tray enters tank body, while the water at low temperature of isometric(al) flows out tank body by lower part water distributing tray.It is tiltedly warm in heat-accumulating process
Layer is gradually reduced from hot water inlet, final to disappear.So far, heat-accumulating process is completed.
When heat source quantity of heat production is less than user's heat amount, accumulation of heat water pot enters heat release state.Exothermic process：Since the external world uses
Heat demand needs the heat that will be stored in heat-accumulator tank to discharge.Start heat release circulating pump, water at low temperature by lower part water distributing tray into
Enter in tank, while high-temperature water is flowed out by top water distributing tray, supply user, mesolimnion with the beginning of heat release process and gradually on
It moves, until completely disappearing, heat release process terminates.Be filled with water at low temperature in heat-accumulator tank at this time, wait heat-accumulating process next time into
Row.
To avoid the water dissolved oxygen in accumulation of heat water pot and bringing these water into heat supply network, heat supply network water quality, accumulation of heat water pot are reduced
It is usually filled with nitrogen or steam on interior liquid level, makes water and air insulated in accumulation of heat water pot.
Vacuum heat-preserving, aeroge heat preservation etc. can be used in heat-accumulator tank moderate soak.Keep the temperature the improper accumulation of heat that can reduce heat-accumulator tank
Performance, which even results in, cannot achieve thermal stratification in heat-accumulator tank.The thermal insulation material of tank bottom should select that heat transfer coefficient is small, compressive resistance
Good thermal insulation material.
(1) vacuum heat-preserving
Vacuum heat-insulating plate is a kind of thermal insulation material of superadiabatic.Because its thermal coefficient is extremely low, so meeting identical guarantor
When temperature technique requires, with insulation layer thickness advantage thin small in size, light-weight, it is higher and require heat preservation to be suitable for power conservation requirement
Material volume occasion that is small, light-weight, having larger Technological Economy meaning.
The thermal coefficient of general thermal insulation material is 0.03W/mK or so at present, and the thermal coefficient of vacuum heat-insulating plate is then
0.004W/mK or so, thickness 20mm or so.The appearance of vacuum heat-insulating plate (VIP) is as shown in Figure 4.
(2) aeroge is kept the temperature
Aeroge is a kind of solid matter form, one of the solid of world's upper density very little.Density is 3 kilograms every cube
Rice.General common aeroge is silica aerogel.Because density is extremely low, most light aeroge only has 0.16 milligram every cube at present
Centimetre, it is more slightly lower than atmospheric density, since general 80% or more is air in aeroge, so have extraordinary heat insulation, one
The heat insulating function of suitable 20 to the 30 blocks of simple glasses of the aeroge of very little thickness.
The room temperature thermal coefficient of aeroge can achieve 0.020W/mK, be thermally conductive in current conventional vacuum heat-barrier material
Coefficient is minimum.Aeroge thermal insulation material can reach fire-protection rating A1 grade standard, non-ignitable rank.
Distributed heat-accumulator tank act only on that corresponding heat exchange station covered for thermal region (secondary network), be mainly disposed to exchange heat
It stands place, conveniently manages and maintains.

B7 is pumped, water circulating pump A6 and electric control valve II4 are in close state at this time.Heat supply network water supply flows through electronic shut-off valve I1, electronic
It after regulating valve I2, is mixed with the return water after electric control valve III3 is flowed through, mixed water temperature is 98 DEG C, into tank body.
The cold water of tank base exports tank body through circulating pump B7, electronic shut-off valve II5, into heat supply network water return pipeline, through pumps for hot water supply net
Return to basic heat source.
When heat-accumulator tank heat release, electronic shut-off valve I1 and electronic shut-off valve II5 are opened, and close electric control valve I2 and recirculated water
B7 is pumped, electric control valve II4 and water circulating pump A6 is opened.A part of cold water through electronic shut-off valve II5, electric control valve II4 into
Enter tank body, hot water exports tank body through circulating pump A6, into heat supply network water supply line；Another part cold water enters basal heat through circulating pump
Enter heat supply network water supply line after the heating of source.
(2) it is directly connected to mode (distribution pumping system)
As shown in fig. 6, including distributed variable frequency pump 8, the one end the electric control valve III3 connects hot water end, the other end leads to
Cross the arrival end that the distributed variable frequency pump 8 connects electronic shut-off valve II5.
(3) indirect connections
Heat-accumulator tank and the indirect connections once netted are as shown in Figure 7.To avoid heat-accumulator tank to the hydraulic regime once netted
It has an impact, heat-accumulator tank is used with primary net and is indirectly connected with.When the heat that heat source generates is more than user terminal workload demand, accumulation of heat
Tank stores extra heat；When heat supply underload, heat-accumulator tank and the user's heat supply in the same direction of heat source one.

Part.As TE201 > TE201S, heat-accumulator tank starts accumulation of heat, and control system remains TE201 in TE201S during accumulation of heat
Near, the speed of accumulation of heat is controlled by water pump B, while controlling the aperture of electric control valve 2 to maintain the liquid level of heat-accumulator tank to keep not
Become；Work as TE201<Heat-accumulator tank starts heat release when TE201S, and control system remains TE201 in TE201S during exothermic
Near, exothermic speed is controlled by water pump A, while controlling the aperture of electric control valve 4 to maintain the liquid level of heat-accumulator tank to keep not
Become.Primary net flow F101 is remained unchanged by controlling the aperture of electric control valve 9 during storage is exothermic.
(2) using the cold and hot water outlet temperature of heat-accumulator tank as stopping accumulation of heat and exothermic condition.Under accumulation of heat operating condition, work as storage
When hot tank cold water pipe temperature TE106 is equal to a net supply water temperature TE101, stop accumulation of heat；Under heat release operating condition, when heat-accumulator tank hot water
When tube temperature degree TE105 is equal to two net return water temperature TE104 of heat exchanger, stop heat release.
