Detailed description of the invention
Embodiment one
The energy storage of the present embodiment recycles complete set of equipments as shown in Figure 1, is mounted with the energy storage wall 4 that porcelain rock energy storage brick assembles in the metal shell 1 with circulated air import 3 and hot-blast outlet 7.The shell wall of metal shell 1 has alumina silicate heat-insulation layer 2.Hot-blast outlet 7 is communicated with the airflow inlet of plate type heat exchanger 16, the air stream outlet of this plate type heat exchanger 16 is by the inlet communication of circulation airduct 12 with hot air circulation blower 8, the outlet of this hot air circulation blower 8 is communicated with circulated air import 3 by airduct, thus forms hot air circulation loop.The water export of plate type heat exchanger 16 connects the water inlet of the place heating facility R such as such as hotel, retail shop, office, office building, classroom, laboratory after the outlet pipe 11 that temperature sensor 17 and temp. regulator 14 are housed by high pressured water circuling pump 13, the delivery port of heating facility R connects the flow inlet of plate type heat exchanger by water return pipeline 10, form hot water circulation loop.
The concrete structure of energy storage wall 4 as shown in Figure 2, is the cuboid by the brick one-tenth of porcelain rock energy storage, between the top layer 4-1 and bottom 4-4 of close block, has upper and lower ventilating layer 4-2 spaced apart and electrothermal layer 4-3.Form the runner 4-6 extended towards hot-blast outlet direction by circulated air import between the energy storage brick of ventilating layer 4-2, between the energy storage brick of electrothermal layer 4-3, form the space 4-5 settling electrothermal device 5 perpendicular to circulated air import 3 to hot-blast outlet 7 direction.The porcelain rock energy storage brick of ventilating layer 4-2 and electrothermal layer 4-3 staggers arrangement up and down.Electrothermal device 5 comes from the resistance silk ribbon of 10KV high pressure for power supply.The thermocouple 15 that hot-blast outlet 7 is settled is for monitoring hot blast temperature.Signals collecting in 10KV high voltage power distributing cabinet is in 15, so that temperature control.When adopting 10KV high voltage source, high-pressure section is arranged on nobody-is-safe district, adopts converting equipment to drop to 380V, eliminates expensive transformer, greatly saved cost.10KV power acquisition wye connection, is down to 5773V voltage, then by the method for connecting, the voltage of single channel silk ribbon is down to about 107V, thus both extended service life, be conducive to energy-conserving and environment-protective again, saves manufacturing cost, power bracket 1-100MW.Certainly, place with good conditionsi also can change low pressure into.
The signal output part of temperature sensor 17 connects the temperature signal input be placed in containing the control circuit of PLC in low-voltage distribution cabinet C.The wiring of this control circuit is see Fig. 3, Fig. 4, Fig. 5, and it opens and closes the power supply controlled end that control output end connects electrothermal device, and the speed regulating control output of this control circuit connects the drive motors 1M controlled end of hot air circulation blower 8 by frequency converter.2M is high pressured water circuling pump motor.
PLC is in order to control cut-out, closed electrical thermal device power supply according to electric wind peak, paddy period;
Judge whether the temperature value that receives is in setting range, then keeps present situation in this way, as otherwise slow down or the control signal that raises speed higher or lower than corresponding outputs of setting range according to temperature value;
When exporting deceleration control signal, judge whether to reach setting lower limit, as otherwise control to lower described drive motors rotating speed, then control electrothermal device dump in this way;
When exporting speed-raising control signal, judge whether to reach capping, as otherwise control to promote described drive motors rotating speed, then control electrothermal device power supply in this way closed.
Energy storage brick of the present invention is porcelain rock energy storage brick, is made by following steps:
The first step. pulverize---potsherd and limestone are crushed to particle diameter 20 ~ 35 order respectively;
Second step. mixing---using the pottery after flour and rock grain and as binding agent white clay (i.e. kaolin) by volume part 5:3 ~ 4 (best 3.5): the ratio of 1 ~ 2 (best 1.5) matches, and the water adding gross weight 10-15% (best 13%) stirs mixing;
3rd step. shaping---blank is made in mixed batching mold pressing;
4th step. sintering---keep constant temperature 24 hours (± 2 hours) to be shaped at the temperature sintering of about 1850 DEG C (± 50 DEG C) blank.
The energy storage brick not only twice laid adopting the present invention to make, economical, and pressed density is high, and (proportion can reach 2.30g/CM
3), there is higher thermal capacity, therefore there is desirable heat energy storage ability, and good insulation preformance under high temperature.
During operation, in the low power consumption period at a low price, electrothermal device (the present embodiment is specially electric heating silk ribbon) electrified regulation in energy storage wall, plate type heat exchanger is being passed through by hot air circulation blower, after water circulation system heat exchange, to heating facility heating while, also by unnecessary heat storage in energy storage wall.In the peak of power consumption period of high price, although electrothermal device power-off stops heating, the heat being stored in energy storage wall still can continue heating hot water by plate type heat exchanger, thus maintains the heat demand meeting heating facility; Only have when off-position really cannot by hot water heating to about 80 DEG C time, just temporarily electrified regulation, therefore operating cost economy, and be conducive to energy-conserving and environment-protective.Such as, low ebb electricity price before somewhere morning is 0.39 yuan/degree, and the electricity price 1.39 yuan in morning 7.30 to 12,12 is 1.15 yuan/degree to 0.91 yuan of average electricity price at midnight, and price difference is 1.15 yuan-0.39 yuan=0.76 yuan, and the heat therefore often storing up kilowatt-hour just can fall this about 0.76 yuan.
