The specific embodiment
With reference to the accompanying drawings the utility model is carried out more detailed description.
Fig. 1 is the central cross-sectional view that effluxes vapour-recovery unit of the utility model.As shown in Figure 1; The utility model efflux vapour-recovery unit, comprise shell 1 (its cross section is for circular), wherein with steam inlet and outlet; In said shell 1, be provided with gas-liquid heat exchange layer 2, spray thrower 3, heat exchange coil 4 and demister 5 successively from the steam inlet to outlet.The utility model efflux the top of deciding row dilatation jar of vapour-recovery unit operated by rotary motion at boiler or drum, can also be connected with blow-down pipe at the said steam (vapor) outlet of arranging the dilatation jar surely.
Said gas-liquid heat exchange layer 2 is grid packing or ripple packing.Can use existing any grid packing and ripple packing, as long as the pressure that it can not cause deciding row's dilatation jar obviously rises.Said gas-liquid heat exchange layer 2 next-door neighbour arrange dilatation tank top steam (vapor) outlet surely.The top of said gas-liquid heat exchange layer 2 sprays normal-temperature water downwards, and bottom steam upwards carries out the abundant heat exchange of carbonated drink large tracts of land in said gas-liquid heat exchange layer 2, reclaims carbonated drink.Said grid packing or ripple packing can fully reduce pressure drag.The whole height of said gas-liquid heat exchange layer is 20～30cm.
In one embodiment, the voidage of said grid packing and ripple packing is 85%～91%, specific area is 200～100m
2/ m
3For example, can be that voidage is 85%, surface area is 160m
2/ m
3Ripple packing; Perhaps can be that voidage is 90%, specific area is 200m
2/ m
3Grid packing.
The cross section of said shell 1 is circular.Be appreciated that in actual use the cross section of said shell 1 can be multiple shapes such as circle, rectangle, triangle.But, preferably, be circle.
Said spray thrower 3 is for having the disk of nozzle.The outside diameter of said disk is less than said shell 1 internal diameter 10～20mm.Said nozzle is a plurality of and evenly is arranged on the bottom of disk.The diameter of said nozzle is 2～15mm, is preferably 3～10mm.Water from said heat exchange coil 4 is descended by said nozzle spray, thereby carbonated drink is carried out surface-type and hybrid cooling, reclaims carbonated drink.Be appreciated that in actual use said spray thrower 3 should be to have and said shell 1 corresponding shape.
The whole height of said heat exchange coil 4 is 20～30cm.Said heat exchange coil 4 inserts cooling waters, and carbonated drink is reclaimed in heat exchange once more when steam rises to said heat exchange coil 4.
Said demister 5 is worn the type demister for height.Can use existing any high type demister of wearing, as long as the pressure that it can not cause deciding row's dilatation jar obviously rises.The whole height of said demister 5 is 10～20cm.Said demister 5 plays the effect of vapor-liquid separation, and simultaneously said demister 5 enlarges the vapour phase area, and outside air further cools off vapour phase, reclaims carbonated drink.In addition, height is worn type demister 5 and can be avoided normal pressure to arrange the dilatation jar surely effluxing vapour-recovery unit and cause pressure obviously to rise because of setting up this.
Further, on said heat exchange coil 4, be provided with valve 6.Control the inlet amount in the said heat exchange coil 4 of cooling water (for example, can be running water) entering through controlling said valve 6, thereby regulate the water spray of said spray thrower 3, adapt to the operating mode of deciding the fluctuation of row's dilatation jar steam discharge thus.During ordinary production, arrange dilatation jar quantity of steam surely and come from platoon, this moment, quantity of steam was stable, regulated the control of cooling water inlet amount and arranged dilatation jar blow-down pipe surely and do not have steam just and emerge; During the intermittent periodic blowdown, arrange the influence that dilatation jar quantity of steam is decided row surely, quantity of steam fluctuation is bigger, and the inlet amount that the said valve of manual adjustments is regulated cooling water is thus controlled and decided row's dilatation jar blow-down pipe and do not have steam just and emerge.
Following embodiment only is used to the utility model of explaining, and unrestricted the utility model.
