Operation principle and the course of work of steam utilization condensation water recovery system are as follows:
The steam pressure that boiler produces is about 1.0MPa, the steam that boiler produces flows to high-temperature technology equipment, low temperature process equipment, combined air conditioner through jet chimney, the main inlet pipe of steam is in delivering vapor process, because steam main inlet pipe length is longer, heat radiation can produce condensed water, condensed water in the main inlet pipe of steam exports through the second drain valve group, and the condensate temperature of output is more than 100 DEG C; Steam flows to high-temperature technology equipment through the first steam inlet tube, high-temperature technology equipment is low pressure gas utilization unit, steam is after the pressure-reducing valve that high-temperature technology equipment carries is depressurized to below 0.5MPa, export through the 4th drain valve group by being condensed into condensed water after high-temperature technology equipment heating pipe tobacco, the condensate temperature of output is more than 100 DEG C; Steam flows to low temperature process equipment through the second steam inlet tube, low temperature process equipment is high pressure gas utilization unit, be condensed into condensed water after the steam of 1.0MPa directly heats pipe tobacco in low temperature process equipment to export through the first drain valve group, the condensate temperature of output is more than 100 DEG C; Steam is depressurized to below 0.3MPa through reducer unit again through the 3rd steam inlet tube and flows to combined air conditioner, and the condensed water being condensed into less than 60 DEG C give air heat in combined air conditioner after exports through the 3rd drain valve group.Because the condensate temperature of the second drain valve group, the 4th drain valve group, the first drain valve group output is more than 100 DEG C, the condensate temperature that 3rd drain valve group exports is below 60 DEG C, two kinds of condensate temperatures and pressure gap larger, if through same recovery channel and condensate water recovery device, high-temp high-pressure condensation water can affect the discharge of low-temp low-pressure condensed water.Therefore the condensed water (condensed water that the main inlet pipe of steam, high-temperature technology equipment, low temperature process equipment produce) of more than 100 DEG C is reclaimed into a high pressure condensate water recovery device through a condensed water main pipeline (the first recovery channel), the condensed water (condensed water of combined air conditioner) of less than 60 DEG C reclaims into a low pressure condensate water recovery device through another root condensed water main pipeline (the second recovery channel) separately.
Pipeline after high-temperature condensation water pipeline i.e. the second drain valve group, the 4th drain valve group, the first drain valve group converges on first recovery channel, enter flash tank through the 3rd ball valve, the 15 ball valve, the 16 ball valve, first emptying valve, second emptying valve are closed at ordinary times.Flow to bottom flash tank after the first metre filter of flash tank.When first filter dirty more time, the 4th ball valve can be opened and drain dirty.Flash drum overhead is provided with two-way motor-driven valve, pressure setting opened by two-way motor-driven valve by control system is 0.06MPa, closing presure is set as 0.03MPa, when the pressure in flash tank is greater than 0.06 MPa, two-way motor-driven valve is opened automatically, the flash steam that high-temperature condensation water produces is through two-way motor-driven valve, the 17 ball valve again on the 14 recovery channel enters in oxygen-eliminating device the demineralized water heating oxygen-eliminating device, the flash steam that so not only high-temperature condensation water produces is utilized, and flash tank is by its top two-way motor-driven valve step-down, also the pressure in flash tank and condensate-water polishing pipeline is just reduced, avoid recovery system to sprain to press and impact to voltage process equipment, the normal discharge of low pressure process equipment and the main inlet pipe condensed water of steam.When the pressure of flash tank and condensate system is lower than 0.03 MPa, two-way motor-driven valve cuts out, pressure in such flash tank can ensure condensed water to compress into high pressure condensing hot air furnace tank through the 9th ball valve, the 6th drain valve group, the 8th ball valve, flows to high pressure condensing hot air furnace pot bottom after the 3rd metre filter of high pressure condensing hot air furnace tank.When the 3rd filter dirty more time, the tenth ball valve can be opened and drain dirty, and high pressure condensing hot air furnace pot bottom has the first blowoff valve.First emptying valve and second emptying valve are closed at ordinary times, and the 4th water pump controls according to the liquid level of high pressure condensing hot air furnace tank.The condensed water of high pressure condensing hot air furnace pot bottom is delivered to equipment for removing ferric ion by the 4th water pump through the 11 ball valve, and condensed water, after the first equipment for removing ferric ion removes iron ion and other impurity, enters the second electric three-way valve.Second electric three-way valve is connected with iron ion on-line computing model, and when the iron concentration after deironing reaches below normal concentration, the descending closedown of the second electric three-way valve, uply opens, and condensed water is crossed the second electric three-way valve and entered oxygen-eliminating device through the 12 ball valve.When iron concentration after condensed water deironing is still more than normal concentration, can not recycle, second electric three-way valve is descending to be opened, up closedown, condensed water is crossed the second electric three-way valve and is entered boiler periodical blowdown expansion drum, arrange into trench through the overflow pipe of periodical blowdown expansion drum after preliminary cooling in periodical blowdown expansion drum, drain into outdoor blowdown cooling tank through trench.
Although the condensate temperature that high-temperature technology equipment produces is more than 100 DEG C, but high-temperature technology equipment is low pressure gas utilization unit, the condensate temperature that the condensate temperature produced and pressure produce than the main inlet pipe of steam, low temperature process equipment etc. and pressure low, the condensed water of such low temperature process equipment and connecting pipe generation thereof may affect the normal discharge of high-temperature technology equipment condensed water.Therefore, after the 4th drain valve group of high-temperature technology equipment, install a set of steam power drain valve pump additional, steam power drain valve pump is equivalent to drain valve not having in dynamic situation.When the condensed water pressure after the 4th drain valve group is enough to the back pressure water delivery overcoming condensate water main pipeline, condensed water directly overcomes back pressure by steam power drain valve pump and exports.When the condensate water pressure after the 4th drain valve group can not overcome the back pressure water delivery of condensate water main pipeline, along with the rising of condensed water liquid level in steam power drain valve pump, inter-interlock mechanism action, steam is after reducer unit decompression, enter steam power drain valve pump to pressurize to condensed water, condensed water pressure is raised and overcomes pipeline back pressure, in steam power drain valve pump, condensed water is arranged into the first recovery channel.Before power steam enters steam power drain valve pump, power steam pipeline installs second water leg additional, the power steam quality entering steam power drain valve pump like this can be higher, avoids affecting water delivery.And the condensed water in the second water leg flows to the first water leg by the 5th drain valve group.14 ball valve and the pipeline installed are the condensation balance pipe of steam power drain valve pump, condensation balance pipe is used in equilibrium vapor power drain valve pump and pressure between anterior condensed water, avoids remaining vapour in steam power drain valve pump to affect anterior condensed water and flows in steam power drain valve pump.First water leg also plays the effect of the favourable water delivery of equalizing pressure.
Steam power drain valve pump also can according to high-temperature technology machine operation and the parallel connection of the 4th drain valve group, when the condensation water quantity of high-temperature technology equipment can overcome again pipeline back pressure comparatively greatly, condensed water can pass through the 4th drain valve group and the water delivery of steam power pump simultaneously, and conveyance power of water strengthens.Even if the condensed water pressure that high-temperature technology equipment produces can not overcome pipeline back pressure and export from the 4th drain valve group, power steam works, and also can be exported by steam power drain valve pump, and conveyance power of water is also larger when power steam is enabled.
First emptying valve near high pressure condensing hot air furnace tank, second emptying valve is closed at ordinary times, when the 8th ball vaeves failures of flash drum overhead can not be opened, or the steam in the main inlet pipe of steam leaks into condensate return system by the second drain valve group, 8th ball valve step-down is slower, during internal system hypertonia, can by first emptying valve, second emptying valve is opened, part flash steam is entered outdoor, part is recycled through threeway the 8th ball valve, realize quick pressure releasing condensate return system, reaching can not affect workshop because above reason hinders condensed water elimination and normally produce.
First emptying valve, second emptying valve, the 15 ball valve are closed at ordinary times, and condensing hot air furnace is enclosed condensation water recovery system.If flash tank breaks down, 15 ball valve can be opened, 3rd ball valve is closed, first emptying valve is opened, high-temperature condensation water pipeline i.e. the second drain valve group, 4th drain valve group, pipeline after first drain valve group converges on the 13 recovery channel, condensed water enters flash tank without the 3rd ball valve, but directly flow to high pressure condensing hot air furnace tank through the 15 ball valve and the 8th ball valve successively, high temperature flash steam is outside the direct discharge chamber of first emptying valve, become open type condensation water recovery system, even if thus flash tank fault also can not affect the condensing hot air furnace of process equipment.
The condensate temperature of combined air conditioner is generally below 60 DEG C, and temperature and pressure is all lower, if adopt same recovery channel and retracting device with more than 100 DEG C high-temp high-pressure condensation waters, high-temperature condensation water can affect the condensed water normal discharge of combined air conditioner.Therefore, the condensed water of combined air conditioner enters low pressure condensation water recovery tank through the 3rd drain valve group, the 5th ball valve, flow to bottom low pressure condensation water recovery tank after the second filter of low pressure condensation water recovery tank, when second filter dirty more time, the 6th ball valve can be opened and drain dirty.Condensed water in low pressure condensation water recovery tank is delivered to the second equipment for removing ferric ion by the 3rd water pump through the 7th ball valve, and condensed water enters the first electric three-way valve remove iron ion and other impurity in the second equipment for removing ferric ion after.First electric three-way valve is connected with iron ion on-line computing model, and when the iron concentration after deironing reaches below normal concentration, the descending closedown of the first electric three-way valve, uply opens, and condensed water is crossed the first electric three-way valve and entered oxygen-eliminating device through the 12 ball valve.When iron concentration after condensed water deironing is still more than normal concentration, can not recycle, first electric three-way valve is descending to be opened, up closedown, condensed water is crossed the first electric three-way valve and is entered boiler periodical blowdown expansion drum, overflow pipe again through boiler blow-off expansion drum is arranged into trench, drains into outdoor blowdown cooling tank through trench.
3rd exhaust-valve at low pressure condensation water recovery tank top is closed at ordinary times, system is enclosed condensation water recovery system, enter condensate return system when combined air conditioner has drain valve to lead directly to Lou vapour or have the by-passing valve of people's maloperation drain valve group to make steam enter condensation water recovery system, when causing condensation water recovery system pressure to raise, 3rd exhaust-valve can be opened, enclosed condensation water recovery system is become Recovery with Open-loop system, intrasystem pressure is discharged fast, thus does not affect the discharge of equipment condensed water and the recovery of condensed water.
16 ball valve is closed at ordinary times, the 16 ball valve can make high-temperature condensation water recycling can and cryogenic condensation water recovery tank for subsequent use each other, as long as opened by the exhaust-valve of the condensing hot air furnace tank top of one of them system, becoming Recovery with Open-loop system just can be for subsequent use each other.When high pressure condensing hot air furnace tank or the first equipment for removing ferric ion fault, 16 ball valve can be opened, 8th ball valve, the 3rd ball valve are closed, 3rd exhaust-valve is opened cryogenic condensation Water Sproading and becomes Recovery with Open-loop system, high-temperature condensation water directly enters low pressure condensation water recovery tank through the 15 ball valve, the 16 ball valve successively from the 13 recovery channel.Equally, when low pressure condensation water recovery tank or the second equipment for removing ferric ion fault, first emptying valve is opened high-temperature condensation water recovery and become Recovery with Open-loop system, low pressure condensed water enters high pressure condensing hot air furnace tank through the 16 ball valve and the 8th ball valve successively.
If the pressure reduction that control system detects equipment for removing ferric ion inside is comparatively large, what prove in equipment for removing ferric ion is dirty more, and the first equipment for removing ferric ion and the second equipment for removing ferric ion need regularly to utilize demineralized water to carry out backwash.When the first equipment for removing ferric ion backwash, the demineralized water of softening water station enters the first equipment for removing ferric ion through the 19 ball valve, the 20 ball valve successively by the first water pump, and the water of backwash enters trench through the 4th blowoff valve.When the second equipment for removing ferric ion backwash, the demineralized water of softening water station enters the second equipment for removing ferric ion through the 19 ball valve, the 18 ball valve successively by the first water pump, and the water of backwash enters trench through the 5th blowoff valve.If need automatically to control, only need to install electrically operated valve or operated pneumatic valve additional.
Oxygen-eliminating device be mainly boiler deoxygenation is provided after demineralized water.Oxygen-eliminating device deoxygenation is mainly by the Steam Heating of boiler.Boiler Steam by Cemented filling through the second magnetic valve to oxygen-eliminating device, the water of oxygen-eliminating device by after the second water pump pressurization through the second ball valve for boiler provides moisturizing.Therefore, flash steam can economize energy by the absorption of the water of oxygen-eliminating device.
Supply water to oxygen-eliminating device through the first ball valve after the demineralized water of softening water station is pressurizeed by water pump, the water of oxygen-eliminating device by after the second water pump pressurization through the second ball valve for boiler provides moisturizing.The steam that boiler produces gives the equipment such as oxygen-eliminating device, high-temperature technology equipment, low temperature process equipment, combined air conditioner through the main inlet pipe of steam, the condensed water that above equipment and pipeline produce reclaims into condensate water recovery device through drain valve group, condensed water, through the qualified laggard oxygen-eliminating device of deironing, then enters boiler develops steam vapor again.Material is thus formed the steam and condensate system of a circulation.After boiler blowdown water and deironing, still defective condensed water enters periodical blowdown expansion drum, and in blowdown expansion drum, after preliminary cooling, draining trench is entered in overflow, drains into outdoor blowdown cooling tank through trench.
In sum, high temperature and low temperature two kinds of condensed waters are divided into two system recoveries by steam utilization condensation water recovery system, reclaimer can be for subsequent use each other, can closed-style recycling system be converted to Recovery with Open-loop system again when condensation water recovery system fault, flexibility and reliability improve greatly, overcome temperature, the different condensing hot air furnace difficult problem caused of pressure that different water delivery point exports condensed water.Because the utility model becomes water to reclaim again into boiler from boiler output steam to steam-condensation, define comparatively perfect closed cycle, the recovery utilization rate of the heat of condensed water, water, flash steam is improved greatly, the pollution of not only having saved resource but also having decreased environment.

Operation principle of the present utility model and the course of work as follows:
The steam pressure that boiler produces is about 1.0MPa, the steam that boiler produces flows to high-temperature technology equipment 104, low temperature process equipment 105, combined air conditioner 106 through jet chimney, the main inlet pipe 113 of steam is in delivering vapor process, because steam main inlet pipe 113 length is longer, heat radiation can produce condensed water, condensed water in the main inlet pipe 113 of steam exports through the second drain valve group 1, and the condensate temperature of output is more than 100 DEG C; Steam flows to high-temperature technology equipment 104 through the first steam inlet tube 114, high-temperature technology equipment 104 is low pressure gas utilization unit, steam is after the pressure-reducing valve that high-temperature technology equipment 104 carries is depressurized to below 0.5MPa, be condensed into condensed water after heating pipe tobacco by high-temperature technology equipment 104 to export through the 4th drain valve group 4, the condensate temperature of output is more than 100 DEG C; Steam flows to low temperature process equipment 105 through the second steam inlet tube 115, low temperature process equipment 105 is high pressure gas utilization unit, be condensed into condensed water after the steam of 1.0MPa directly heats pipe tobacco in low temperature process equipment 105 to export through the first drain valve group 7, the condensate temperature of output is more than 100 DEG C; Steam is depressurized to below 0.3MPa through reducer unit again through the 3rd steam inlet tube 116 and flows to combined air conditioner 106, and the condensed water being condensed into less than 60 DEG C give air heat in combined air conditioner 106 after exports through the 3rd drain valve group 9.Because the condensate temperature of the second drain valve group 1, the 4th drain valve group 4, first drain valve group 7 output is more than 100 DEG C, the condensate temperature that 3rd drain valve group 9 exports is below 60 DEG C, two kinds of condensate temperatures and pressure gap larger, if through same recovery channel and condensate water recovery device, high-temp high-pressure condensation water can affect the discharge of low-temp low-pressure condensed water.Therefore the condensed water (condensed water that the main inlet pipe 113 of steam, high-temperature technology equipment 104, low temperature process equipment 105 produce) of more than 100 DEG C is reclaimed into a high pressure condensate water recovery device through a condensed water main pipeline (the first recovery channel 119), the condensed water (condensed water of combined air conditioner 106) of less than 60 DEG C reclaims into a low pressure condensate water recovery device through another root condensed water main pipeline (the second recovery channel 121) separately.
Pipeline after high-temperature condensation water pipeline i.e. the second drain valve group 1, the 4th drain valve group 4, first drain valve group 7 converges on first recovery channel 119, enter flash tank 107 through the 3rd ball valve 52, close when the 15 ball valve the 49, the 16 ball valve 13, first emptying valve 46, second emptying valve 48 are flat.Flow to bottom flash tank 107 after the first filter 51 of flash tank 107 filters.When first filter 51 dirty more time, the 4th ball valve 53 can be opened and drain dirty.Flash tank 107 top is provided with two-way motor-driven valve 50, pressure setting opened by two-way motor-driven valve 50 by control system is 0.06MPa, closing presure is set as 0.03MPa, when the pressure in flash tank 107 is greater than 0.06 MPa, two-way motor-driven valve 50 is opened automatically, the flash steam that high-temperature condensation water produces is through two-way motor-driven valve 50, the 17 ball valve 40 again on the 14 recovery channel 139 enters the demineralized water heating oxygen-eliminating device 101 in oxygen-eliminating device 101, the flash steam that so not only high-temperature condensation water produces is utilized, and flash tank 107 is by its top two-way motor-driven valve 50 step-down, also the pressure in flash tank 107 and condensate-water polishing pipeline is just reduced, avoid recovery system to sprain to press and impact to voltage process equipment 104, the normal discharge of low pressure process equipment 105 and steam main inlet pipe 113 condensed water.When the pressure of flash tank 107 and condensate system is lower than 0.03 MPa, two-way motor-driven valve 50 cuts out, pressure in such flash tank 107 can ensure condensed water to compress into high pressure condensing hot air furnace tank 108 through the 9th ball valve 10, the 6th drain valve group 11, the 8th ball valve 47, flows to bottom high pressure condensing hot air furnace tank 108 after the 3rd filter 45 of high pressure condensing hot air furnace tank 108 filters.When the 3rd filter 45 dirty more time, the tenth ball valve 12 can be opened and drain dirty, and have the first blowoff valve 14 bottom high pressure condensing hot air furnace tank 108.First emptying valve 46 and second emptying valve 48 flat time close, the 4th water pump 44 controls according to the liquid level of high pressure condensing hot air furnace tank 108.Condensed water bottom high pressure condensing hot air furnace tank 108 is delivered to equipment for removing ferric ion 1 by the 4th water pump 44 through the 11 ball valve 43, and condensed water, after the first equipment for removing ferric ion 110 removes iron ion and other impurity, enters the second electric three-way valve 29.Second electric three-way valve 29 is connected with iron ion on-line computing model, when the iron concentration after deironing reaches below normal concentration, the descending closedown of second electric three-way valve 29, uply opens, and condensed water is crossed the second electric three-way valve 29 and entered oxygen-eliminating device 101 through the 12 ball valve 41.When iron concentration after condensed water deironing is still more than normal concentration, can not recycle, second electric three-way valve 29 is descending to be opened, up closedown, condensed water is crossed the second electric three-way valve 29 and is entered boiler periodical blowdown expansion drum 103, arrange into trench through the overflow pipe 30 of periodical blowdown expansion drum 103 after preliminary cooling in periodical blowdown expansion drum 103, drain into outdoor blowdown cooling tank through trench.
