The height in described slow pressure storehouse 4 and standby slow pressure storehouse 14 is more than or equal to the height of described boiler water filling position limit switch 8.
The valve A of the present invention, valve C, valve B, valve D, valve A ', valve C ', valve B ', valve D ' and back-water valve (BWV) 13 are all adopt prior art, under boiler water filling position limit switch and boiler, water level limit switch is also adopt prior art, under boiler water filling position limit switch 8 and boiler, water level limit switch 9 sends according to the water level height in boiler and triggers signal, upper water level limit switch 10 and lower water level limit switch 11 send triggering signal according to the water level height in slow pressure storehouse 4 and standby slow pressure storehouse 14, division board limit switch 20 sends triggering signal by the shake-up of division board.This is prior art, does not repeat them here.
The invention also discloses a kind of unpowered water compensating control method of steam boiler, comprise the steps:
(1) opening: slow pressure storehouse 4 starts, open valve B5 and valve D6, division board 12 rapid increase under the drive driving cylinder 19 in slow pressure storehouse in slow pressure storehouse 4 simultaneously, give storehouse 4 water-retention of slow pressure, until the water level upper limit position switch 10 in slow pressure storehouse 4 sends the full signal i1h of water, slow pressure storehouse stops water-retention, closes valve B5 and valve D6；Open valve B ' and valve D ', simultaneously, the division board in standby slow pressure storehouse 14 is rapid increase under the drive driving cylinder, to standby slow pressure storehouse 14 water-retention, until the water level upper limit position switch in standby slow pressure storehouse 14 sends the full signal I ' 1h of water, standby slow pressure storehouse stops water-retention, closes valve B ' and valve D '；
(2) boiler water level lower position switch 9 sends early warning signal；
(3) if slow pressure storehouse 4 is in the full state of water, then the moisturizing of Boiler High Pressure storehouse is given in slow pressure storehouse 4；
(4) if the water level lower position switch in slow pressure storehouse 4 sends early warning signal and standby slow pressure storehouse 14 is in the full state of water, Boiler High Pressure storehouse 1 moisturizing is given in standby slow pressure storehouse 14, and slow pressure storehouse 4 starts from moisturizing；
(5) if the water level lower position switch in standby slow pressure storehouse 14 sends early warning signal, standby slow pressure storehouse 14 starts from moisturizing；
(6) repeating step (3)-(5), until boiler water level upper limit position switch 8 sends early warning signal, moisturizing terminates.
In described step (3), slow pressure storehouse 4 includes following process to blast furnace high-pressure chamber 1 moisturizing:
Valve A2 and valve C3 opens, valve B5 and valve D6 closes, slow pressure storehouse 4 manufactures high-pressure balancing, softening water in slow pressure storehouse 4 is used water-head and is utilized deadweight to flow in Boiler High Pressure storehouse 1 through valve A2, simultaneously, high steam flows into slow pressure storehouse 4 by valve C3, and pressurized is to the division board 12 in slow pressure storehouse, division board 12 is driving cylinder 19 moved downward, drive 19 2 pressing aids of cylinder, accelerate moisturizing speed, back-water valve (BWV) 13 has single-phase flow, under the effect of division board 12, aqueous water and high steam are isolated, vapour-liquid will not be occurred to inhale molten phenomenon, until the water level lower position switch in slow pressure storehouse 4 sends early warning signal, division board 12 stops moving downward.
The standby slow pressure storehouse 14 of described step (4) is as follows to the process of Boiler High Pressure storehouse 1 moisturizing:
Valve A ' 15 and valve C ' 16 opens, valve B ' 17 and valve D ' 18 closes, standby slow pressure storehouse 14 manufactures high-pressure balancing, in standby slow pressure storehouse, the softening water of 14 uses water-head utilization deadweight in valve A ' 15 inflow Boiler High Pressure storehouse 1, simultaneously, high steam flows into standby slow pressure storehouse 14 by valve C ' 16, and pressurized is to the division board 12 in standby slow pressure storehouse, division board 12 is driving cylinder 19 moved downward, secondary pressing aid, accelerate moisturizing speed, back-water valve (BWV) 13 has single-phase flow, under the effect of standby slow pressure storehouse division board 12, aqueous water and high steam are isolated, vapour-liquid will not be occurred to inhale molten phenomenon, until the water level lower position switch in standby slow pressure storehouse 14 sends early warning signal, division board 12 stops moving downward.
The slow pressure storehouse 4 self-water replenishing process of described step (4) is as follows:
Valve B5 and valve D6 opens, valve A2 and valve C3 closes, slow pressure storehouse 4 manufactures normal-pressure balance, use water-head, water is utilized to conduct oneself with dignity, softening water flows to slow pressure storehouse 4 from water storing bin 7 through valve B5 and valve D6, simultaneously, division board 12 rapid increase under the drive driving cylinder 19 in slow pressure storehouse 4, when rising to slow pressure 4 top, storehouse, division board 12 triggers division board limit switch 20 and sends triggering signal, back-water valve (BWV) 13 is opened, division board 12 stops moving upward, moisturizing proceeds, until the water level upper limit position switch in slow pressure storehouse 4 sends the full signal of water, stop moisturizing, simultaneously, gas is discharged through valve D6, liquefaction water is on the downside of back-water valve (BWV) stream to division board 12.
The standby slow pressure storehouse self-water replenishing process of described step (5) is as follows:
Standby slow pressure storehouse moisturizing: valve B ' 17 and valve D ' 18 opens, valve A ' 15 and valve C ' 16 closes, standby slow pressure storehouse 14 manufactures normal-pressure balance, use water-head, water is utilized to conduct oneself with dignity, softening water flows to standby slow pressure storehouse 14 from water storing bin 7 through valve B ' 17 and valve D ' 18, simultaneously, the division board 12 in standby slow pressure storehouse 14 is rapid increase under the drive driving cylinder, when rising to 14 top, standby slow pressure storehouse, division board 12 triggers division board limit switch 20 and sends triggering signal, division board 12 stops moving upward, back-water valve (BWV) 13 is opened, moisturizing proceeds, until water level upper limit position switch sends the full signal of water, stop moisturizing, simultaneously, gas is discharged through valve D ', liquefaction water is on the downside of back-water valve (BWV) stream to division board 12.
The present invention can pass through without the technical characteristic described or adopt existing techniques in realizing; do not repeat them here; certainly; described above is not limitation of the present invention; the present invention is also not limited to the example above; the change made in the essential scope of the present invention of those skilled in the art, remodeling, interpolation or replacement, also should belong to protection scope of the present invention.
