Description
Technical field
The utility model relates to jet chimney condensate water recovery device fields more particularly to a kind of jet chimney condensed water to return
Receipts flash tank.
Background technique
Industrial Boiler condensing hot air furnace is to improve one of boiler thermal efficiency, the important channel for reducing energy consumption.The thermal energy of steam
It is made of sensible heat and latent heat two parts, usual gas utilization unit only utilizes latent heat of the steam and a small amount of sensible heat, discharges latent heat and lacks
Steam reduction after the sensible heat of amount is at the condensed water of high temperature, and condensed water is the hot mastication water of saturation, and thermal energy accounts for steam
25% or so of thermal energy, and be also clean distilled water, it is suitble to be re-used as boiler feedwater.
The high-temperature condensation water of condensation water recovery system recovered steam system discharge, can maximally utilise the heat of condensed water
Amount saves water, and saves fuel.Condensation water recovery system is broadly divided into Recovery with Open-loop system and two kinds of closed-style recycling system.
Closed-style recycling system is condensed water header tank and all pipelines all in constant direct draught, and system is closed.In system
Energy possessed by condensed water largely passes through certain reclaimer and is directly recovered in boiler.Industrial Boiler condensed water at present
The problems such as existing flash distillation loss of recovery system is big, recovery system pressure is high, jet chimney condensed water unsmooth flowing, causes steam
The problems such as pipeline condensation water recovery and use rate is low, thermal energy waste is serious.
Important component of the flash tank as condensation water recovery system, there are the following problems in use: carrying out ultromotivity and sets
After standby steam enters the flash tank by steam inlet, due to increasing sharply for volume, steam pressure declines rapidly, institute in steam
The operative liquid steam contained turns to flash steam, is influenced by flash process, and tank interior pressure range is smaller, results in relying on
The efficiency of condensed water is lower in pressure difference recovered steam pipeline.
Utility model content
The utility model provides a kind of jet chimney condensing hot air furnace sudden strain of a muscle to solve shortcoming in the prior art
Steaming pot, overcoming flash distillation influences, and improves the recovery efficiency of condensed water.
In order to solve the above technical problems, the utility model adopts the following technical solution: a kind of jet chimney condensing hot air furnace
With flash tank, including tank body, steam inlet, cooling medium entrance and condensation-water drain, steam inlet are provided on the tank body
It is set to tank body top with cooling medium entrance, and steam inlet is located at the top of cooling medium entrance, is equipped with and cooling in tank body
The cooling medium circulation duct of medium inlet connection, sets spray equipment on cooling medium circulation duct；Condensation-water drain is set to tank
Body lower part.
The cooling medium circulation duct is snake pipe, lays spray apertures on snake pipe and forms the spray equipment.
Top ends of cans is equipped at the open top of the tank body, top ends of cans is bolted connection with tank body.
There are relief valve connections and pressure sensor interface on the top ends of cans.
The tank base is equipped with sewage draining exit.
The utility model has the beneficial effects that
By adopting the above technical scheme, after the steam from power-equipment enters the flash tank by steam inlet, due to volume
Increase sharply, steam pressure declines rapidly, and operative liquid steam contained in steam turns to flash steam；And due to flash tank
It is inside provided with cooling medium circulation duct, from external cryogenic media after cooling medium entrance enters tank body, through cold
But flow of media pipeline and set spray equipment effect atomization after intersperse among tank interior space, certain media and tank interior
Flash steam generate strong heat transfer process so that flash steam is condensed into liquid water and accumulates in tank base, overcome flash distillation
It influences, improves the recovery efficiency of condensed water.
The cooling medium circulation duct is snake pipe, lays spray apertures on snake pipe and forms the spray equipment,
The design is dispersed evenly to tank interior space after cooling medium can be made to be atomized, and improves its exchanging with tank interior flash steam
Efficiency.
There are relief valve connection and pressure sensor interface at the top ends of cans of flash tank, it is easily installed safety valve and pressure passes
Sensor guarantees the safe operation of the device.
The tank base of flash tank is provided with sewage draining exit, periodically opens, meets flash tank blowdown demand.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model；
Fig. 2 is the top view of Fig. 1:
Fig. 3 is A-A diagrammatic cross-section in Fig. 1；

Specific embodiment
It elaborates below in conjunction with attached drawing to specific embodiment of the present utility model.
As shown in Figures 1 to 4, a kind of jet chimney condensing hot air furnace flash tank of the utility model, including tank body 1 with
And the top ends of cans 6 being arranged at 1 open top of tank body, top ends of cans 6 is bolted connection with tank body 1, and is stayed on top ends of cans 6
There are relief valve connection 61 and pressure sensor interface 62, be easily installed safety valve and pressure sensor, guarantees the safety of the device
Operation.
Steam inlet 2, cooling medium entrance 3, condensation-water drain 4, steam inlet 2 and cooling medium are provided on tank body 1
Entrance 3 is set to 1 top of tank body, and steam inlet 2 is located at the top of cooling medium entrance 3, is equipped with to enter with cooling medium in tank body 1
The cooling medium circulation ducts 5 of mouthfuls 3 connections set spray equipment on cooling medium circulation duct 5；Condensation-water drain is set to tank body 1
Lower part.
In the present embodiment, cooling medium circulation duct 5 is snake pipe, lays spray apertures on snake pipe and forms the spray
Shower device, the design are dispersed evenly to tank interior space after cooling medium can be made to be atomized, and improve it and flash with tank interior
