From above-mentioned technical scheme, device of the present utility model is extremely simple, but the effect of its practicality is the most prominent, can make full use of used heat.
Additionally, device of the present utility model is positioned between the water supply outfan of flash column and circulating pump on feed pipe is provided with on it water supply bypass with water supply valve, the inner tip of flash column is also provided with vapour-liquid demister.
Realize in the device of this utility model method, especially in the device reclaiming gaseous state used heat, floss hole at each used heat arranges used heat collecting pipe, multiple collecting pipes are summarised in together, and it is passed into the bottom of vapor absorption tower, arranging multilamellar tower tray inside vapor absorption tower, recirculated water enters from tower top, flows from top to bottom through each layer tower tray；Waste hot steam enters from bottom, flow from bottom to top, both continuous cross-exchange, make circulating water temperature increase, the net quantity of heat of waste hot steam is laid in recirculated water, and the incoagulable gas in waste hot steam is discharged exporting from the incoagulable gas of vapor absorption tower top.Vapor absorption tower stores the recirculated water of waste hot steam net quantity of heat through being sent to hot water flash evaporation tower, owing to the coupling of system pressure and temperature is always used, boiling phenomenon is there is in hot water in flash column, produce indirect steam, indirect steam, through the high efficiency filter effect of flash column vapour liquid separator, becomes to clean pure, enters into the latter linked load of this utility model device after indirect steam outlet is discharged, such as vaporizer, interior uses as heat source；Water level in hot water flash evaporation tower automatically turns on control valve to its moisturizing when reducing.
The indirect steam that this utility model is discharged from hot water flash evaporation device can individually supply subsequent evaporation device, it is also possible to as after supplementary steam and other incoming road steam in the lump for vaporizer.The indirect steam outlet of hot water flash evaporation device is general to be connected with tradition multi-effect evaporator, and it connects principle is pressure and temp coupling, makes to be formed in hot water flash evaporation device the most lasting flash distillation.The indirect steam of hot water flash evaporation device forms condensed water after evaporator heat exchange, and vaporizer produces again the indirect steam of self simultaneously, as the thermal source of more rear stage evaporation.So in this utility model, waste hot steam is the most effectively utilized, and produces without any pollution, is a kind of efficient, energy-conservation complete scheme and effective measures.
This utility model reclaimer is simple, place takies less, and the response rate reaches more than 98%, will not produce any secondary pollution.Can be more convenient and realize recycling after simply existing waste heat discharge being transformed in the product mode of standardization and seriation, comply fully with national existing industrial policy, there is obvious economic benefit and social benefit.

Detailed description of the invention
Method and device of the present utility model explains orally in detail below in conjunction with embodiment, and what the present embodiment was targeted is the Waste Heat Recovery of the injection steam reclaiming papermaking spherical digester steaming and decocting.
For shortening digester cycle, improving paper pulp yield and quality, in paper technology, commonly used multiple rotary spherical digesters spurt steam in turn so that discharging.Spurting steam discharging directly into atmosphere in the past, each rotary spherical digester discharges in turn, rises one after another, and causes energy dissipation and sound pollution.
In the present embodiment, the steam that used heat collecting pipe 1 is connected to each rotary spherical digester spurts mouth, and all of used heat collecting pipe collects and used heat gathering tube 2.The aggregated pipe of waste hot steam 2 enters from the bottom of vapor absorption tower 5, flows from bottom to top；The recirculated water sent here by absorption tower feed pipe 8 enters from tower top, flows from top to bottom through each layer tower tray 7, and both are fully contacted, and constantly produce heat exchange, make circulating water temperature increase, and the net quantity of heat of waste hot steam is laid in recirculated water.Recirculated water after Bei Jiare is gone out water pump 4 by absorption tower and returns in hot water flash evaporation tower 9.Incoagulable gas in waste hot steam exports discharge at the incoagulable gas of vapor absorption tower top.
The indirect steam outlet of flash column 9 is connected with the heater of vaporizer, and because of systemic effect, it is ensured that the hot water in flash column 9 can produce the flass of sufficient intensity, it is provided that flash distillation indirect steam.Flash distillation indirect steam, through the high efficiency filter effect of flash column vapour liquid separator 13, becomes to clean pure, flash column flash steam outlet 14 uses as heat source in entering into the heater of vaporizer 19.Recirculated water in flash column 9 goes out water pump 10 through flash column again and is sent to vapor absorption tower 5 and is circulated heating, in order to continue flash distillation after returning flash column 9, forms one stably continuous print process.Water level in hot water flash evaporation tower 9 is automatically turned on flash column water supply control valve door 11 to its moisturizing by DCS system when reducing.
Vaporizer 19 is the carrier absorbing and using flash distillation indirect steam, generally a certain effect in tradition multi-effect evaporator, and the principle of that effect specifically chosen is the flass that the hot water that this single-effect evaporator can guarantee that in flash column 9 produces sufficient intensity.The indirect steam that flash vessel 9 is discharged can be individually for the vaporizer being attached thereto, it is also possible to as after supplementary steam and other incoming road steam in the lump for the vaporizer being attached thereto.In vaporizer 19 by evaporation liquid by evaporation feed liquor pipe in 24 evaporation feed liquors control the housing that valve 23 enters into vaporizer 19.Discharged by vaporizer circulation fluid outlet 22 in vaporizer 19 by evaporation liquid, under the driving of vaporizer circulating pump 21, flash-pot 19 top enters, it is divided evenly to the individual surface of heater, heat exchange is produced with the steam entered in heater, steam is condensed formation condensed water, discharges from evaporator condensation water outlet pipe 16, enters into evaporator condensation water pot 15 and temporarily store, sent by evaporative condenser water pump 17 again, in system as hot water.Meanwhile, in vaporizer 19, it is heated to boiling point by evaporation liquid, and then produces indirect steam, vaporizer indirect steam outlet 20 for vaporizer thereafter after discharging.So in this utility model, waste hot steam is the most effectively utilized, and produces without any pollution, is a kind of efficient, energy-conservation complete scheme and effective measures.
