Brief description of the drawings
Fig. 1 is schematic front view of the present utility model.
Specific embodiment
Specific embodiment one：Present embodiment is illustrated with reference to Fig. 1, one kind of present embodiment is provided with water-level control apparatus
Heat-accumulator tank, including accumulation of heat can body 1, hot water water distributing tray 2, cold water water distributing tray 3, hot water inlet/outlet pipe 4 and cold water inlet/outlet pipe 5, heat
Water cloth water pond 2 and cold water water distributing tray 3 are arranged inside accumulation of heat can body 1, and hot water water distributing tray 2 is located on accumulation of heat can body 1
Portion, cold water water distributing tray 3 is located at the bottom of accumulation of heat can body 1, and hot water inlet/outlet pipe 4 and cold water inlet/outlet pipe 5 are respectively positioned on outside accumulation of heat can body 1
Portion, and hot water inlet/outlet pipe 4 connects with hot water water distributing tray 2, cold water inlet/outlet pipe 5 is connected with cold water water distributing tray 3,
The inwall of accumulation of heat can body 1 is additionally provided with upper limit position switch 6 and lower position switch 7, upper limit position switch 6 and lower limit
Switch 7 is from top to bottom successively set on the top of hot water water distributing tray 2, and hot water suction pump 8, cold water are provided with hot water inlet/outlet pipe 4
Cold water suction pump 9 is provided with inlet/outlet pipe 5, hot water suction pump 8 is passed through by the control action of lower position switch 7, cold water suction pump 9
The control action of upper limit position switch 6.
The upper limit position switch 6 and lower position switch 7 are electronic type liquid-level switch.
Heat-accumulator tank internal reservoir hot water, because operating pressure is normal pressure, maximum operating temperature is not higher than 98 DEG C.Water temperature is not
Together, the density of water is different, and in enough bulk container, hot water layer 101 is upper, and cold water layer 102 is middle for transition zone under
103, here it is in heat-accumulator tank water the principle of stratification.Heat-accumulator tank is designed and worked according to the principle of stratification of water, and makes it
Work is maintained at high efficiency.
The essence of the heat-accumulator tank course of work is exactly its accumulation of heat exothermic process, in user's underload, unnecessary heat energy is inhaled
Store up and deposit, wait load to be released again when rising and use.When heat-accumulator tank works, should ensure that it imports and exports water balance, keep its liquid level
Stabilization, is at peak work capacity.In addition, being brought into heat supply network to avoid the water dissolves oxygen in heat-accumulator tank, heat supply network is reduced
Water quality, generally steam (or nitrogen) is filled with the liquid level in heat-accumulator tank, keeps pressure-fired, make water and air in heat-accumulator tank every
From.
Heat-accumulator tank is directly connected to heating system, can be as heat supply network pressure fixing system, because heat-accumulator tank remains constant
Liquid level, it can ensure that heating system static pressure is constant, therefore it can be used as the pressure fixing system of heat supply network.
The use of the primary benefits of hold over system is that the generating production that steam power plant can be improved under same thermic load state (subtracts
The condensing operation of few steam power plant), reduce steam power plant's operation at part load.Now heat-accumulator tank be seen as thermal source and heat user it
Between buffer, be mainly used in balance thermic load (elimination peak value) and be thermal source (with transmission ＆ distribution) provide flexibility.Consider peak-trough electricity
Valency, in flexibility and the free degree that steam power plant realizes generating electricity using heat-accumulator tank, improves the economy of steam power plant.
Heat-accumulator tank especially plays an important roll with the stabilization of extraction-condensing steam turbine to back pressure unit with economical operation, it
It is sufficiently used the heat supply of steam power plant.It stores in heat-accumulator tank, in heat supply network peakload shape the cheap heat energy of steam power plant
Under state, heat-accumulator tank and steam power plant's combined heat, it is possible to decrease the heating load of high price spike thermal source optimize the operation of system.
When heating system water pump is out of service suddenly because of accidental cause, water attack will be produced, make power plant inside and heating power
Pipe network suffers very big destruction.If heating system is equipped with heat-accumulator tank, it will significantly alleviate the high-voltage oscillation that water attack is caused, and subtract
Light-water hits the destruction and disaster for causing.
When certain thermal source stops heat supply for some reason, heat-accumulator tank can in time run complementary heating, prevent from causing big face to stop hot shape
State.
When the explosion suddenly of heat supply network somewhere during a large amount of dehydration, the heat-accumulator tank being directly connected to heat supply network is tieed up to heat supply network moisturizing immediately
System pressure is held, in case the accident of whole heat network system and stoppage in transit.
One important function of heat-accumulator tank is the peak load shifting to heating system, and its peak modulation capacity may replace construction spike heat
Source, saves the fuel consumption of spike heat supply factory.
Heating system summer, only for domestic hot-water's load is answered, due to the change at any time of hot water load, causes heat supply network recirculated water
The acute variation of flow, due to pumps for hot water supply net constant speed drive, thus causes the pressure acute variation of heat supply network, in ebb load
When, heating network pressure steeply rises, and threatens the safe operation of system.If having built heat-accumulator tank, it can alleviate the pressure urgency of heat supply network
Play is raised, and makes heating system safe operation.
