The invention also discloses above-mentioned boiler and prevent dryouting the method for safe operation of safety production system, enter by the following method
OK:
Including operation method when properly functioning method and accidental power failure；
Properly functioning method is to start feed pump 7 and boiler, is become by the cool water heating that feed pump 7 is sent into after hot water continuously
Deliver to use heat unit from boiler discharging tube 3；Keep burn-out-proof solid carbon dioxide case 8 and water supply tank 9 to be in the state of full water simultaneously；
Operation method during accidental power failure is:
Staff observes thermometer the 15, first Pressure gauge 23 and the second Pressure gauge 24；When thermometer 15 shows the temperature of heating chamber 1
When degree is higher than 75 degree, in heating chamber 1, existing part water is vaporized；Now opening the first valve 46, the water vapour in heating chamber 1 leads to
Cross the first pipeline 10 and be passed through burn-out-proof solid carbon dioxide case 8, make to be in identical pressure between burn-out-proof solid carbon dioxide case 8 and heating chamber 1；
By the first Pressure gauge 23 and the second Pressure gauge 24, staff confirms that burn-out-proof solid carbon dioxide case 8 is in phase between heating chamber 1
Opening the second valve 12 and atmospheric valve 14 after same pressure, the water in burn-out-proof solid carbon dioxide case 8 flows into heating chamber 1, and at burn-out-proof solid carbon dioxide
In case 8 under the effect of hydraulic pressure, the most heated water and steam in heating chamber 1 flow to heat exchanger shell by after relief valve 25
29, finally flow into tank 26；When the pressure in heating chamber 1 is higher than the unlatching pressure of relief valve 25, the pressure in relief valve 25
Spring 42 is compressed, and taper valve core 43 leaves horn mouth 39, so that steam and water in heating chamber 1 by horn mouth 39 and support
Orifice plate 41, enters the bottom of tank 26 through the 5th pipeline 33 after flowing through the air-cooled heat exchanger tube 30 of heat exchanger, steam enters water storage
Absorbed by the water in tank 26 behind pond 26, from without working environment is produced steam contamination.Pressure in heating chamber 1 is more
Height, the distance that taper valve core 43 leaves main pore 38 and secondary pore 40 is the most remote, shape between taper valve core 43 and horn mouth 39 sidewall
The current path become is the widest, and vapour lock is the least, and the water and the steam that pass through in the unit interval are the most, reaches the pressure in heating chamber 1 more
Technique effect high, that release speed is the fastest.The setting of secondary pore 40, it is possible to accelerate release speed, and strengthen in heating chamber 1
The technique effect that pressure is the highest, release speed is the fastest.
When the pressure in heating chamber 1 is less than the unlatching pressure of relief valve 25, at the elastic force effect inferior pyramidal valve of stage clip 42
Core 43 compresses horn mouth 39, the closure main pore 38 of institute and each secondary pore 40, thus closed safe valve 25；
If the most first opening the first valve 46 and directly opening the second valve 12, may cause the water in heating chamber 1 and steam because of
Pressure raises (water in boiler can vaporize because not flowing, and causes pressure to raise) and flows backwards to burn-out-proof solid carbon dioxide case 8, so will
Cause the water in burn-out-proof solid carbon dioxide case 8 cannot flow downwardly into heating chamber 1, until the water in heating chamber 1 dryouies, steam pressure is less than anti-
Dryout the hydraulic pressure of water tank 8, thus cause safety problem and steam contamination problem in the process.
In running when accidental power failure, staff persistently carries out following two operation:
1. observe thermometer 15, after thermometer 15 shows that the water temperature of heating chamber 1 is less than 50 degree, close the second valve 12；Heating
Water temperature in room 1 is gone up after more than 75 degree, reopens the second valve 12；This operation is prevented from burn-out-proof solid carbon dioxide case 8
Water too fast inflow heating chamber 1, to such an extent as to do not fully absorb the heat energy in heating chamber 1 and just spilt out by boiler discharging tube 3.This
The meaning of operation is when having a power failure that making full use of water in burn-out-proof solid carbon dioxide case 8 absorbs the ability of heat energy.
2. the liquid level in burn-out-proof solid carbon dioxide case 8 is observed by the first transparent tube 13, when in burn-out-proof solid carbon dioxide case 8, liquid level is less than burn-out-proof
Solid carbon dioxide case 8 height 1/3 time, open the 3rd valve 17 and atmospheric valve 14, make water in water supply tank 9 be injected by the 3rd pipeline 16
Burn-out-proof solid carbon dioxide case 8, burn-out-proof solid carbon dioxide case 8 fills the water in water or water supply tank 9 when using up, closes the 3rd valve 17 and atmospheric valve
14。
In operation method during accidental power failure, staff observes the pressure of the first Pressure gauge 23, when the first Pressure gauge 23
Registration more than or equal to the unlatching pressure of relief valve 25 time, open cooling blower 27, cooling blower 27 draw ambient air general
Surrounding air sends into the housing 29 of heat exchanger along the 7th pipeline 35, flows through after each annulus fin 31 through the 6th pipeline in housing 29
Flow out after 34, thus cool down rapidly the water by air-cooled heat exchanger tube 30 and steam, prevent the water temperature over-high in tank 26, steam
Overflow from tank 26 and form steam contamination.
During use, boiler discharging tube 3 connection heat unit.In heating chamber 1 during hypertonia, the steam water interface temperature of outflow
Spend higher, as by after relief valve 25 directly discharge will produce substantial amounts of steam, pollute working environment, make plant area's wall because of for a long time
Moist and impaired.In the present invention, the steam water interface flowed out from relief valve 25 sends into housing 29, by the air-cooled heat exchange of housing 29
During pipe 30, with pipe outside cooling air-flow generation heat exchange.The setting of annulus fin 31 can be greatly improved heat exchange efficiency, and because of
The flowing of cooling air is the most too much affected for the existence of through hole 45.Most of steam after heat exchange, in vaporization mixture
It is condensed into water, injects the bottom of tank 26 finally by the 5th pipeline 33.
If the 5th pipeline 33 is not passed through the bottom of tank 26, but opening is at tank 26 ullage, then
Still can flow out some vapor from the 5th pipeline 33, environment is caused a small amount of steam contamination；5th pipeline 33 is passed through tank 26
Bottom, then steam can be avoided completely to permeate into the phenomenon in air.
Above example is only in order to illustrative not limiting technical scheme, although with reference to above-described embodiment to this
Bright be described in detail, it will be understood by those within the art that: still the present invention can be modified or etc.
With replacing, any modification or partial replacement without departing from the spirit and scope of the present invention, it all should contain the power in the present invention
In the middle of profit claimed range.
