Embodiment
The utility model is further described with reference to Figure of description.
Embodiment 1
As shown in Figure 1-2, the equal flowing water chuck raw coke oven gas waste-heat recovery device of the present embodiment, by water inlet 1, overcoat 2, protect
Warm layer 3, intermediate sleeve 4, packed layer 5, dividing plate sleeve 6, steam-water heat exchanging space 7, inner cylinder 8, and steam water interface export 9 groups
Into；Described packed layer 5 is made up of the segment space between intermediate sleeve 4 and dividing plate sleeve 6, and the packed density of packed layer 5 is more than
Water, and 3~10mm of diameter not soluble in water solid insulation bead；Described steam-water heat exchanging space 7 is by intermediate cylinder 4 and interior bucket 8
The mezzanine space of formation removes packed layer 5 and dividing plate sleeve 6 is formed.
The presence of packed layer 5 is to provide a space for the radial thermal expansion of dividing plate sleeve 6, avoids causing thermal stress to break
It is bad, when packed layer 5 fills low heat conductivity solid globules equivalent to thermal resistance between increase carbonated drink side and outside.
The quantity of water inlet 1 is more than 2, and water inlet 1 is distributed uniformly and circumferentially.
In course of normal operation, saturation water flows annulus 7-1 by water inlet 1 into bottom, and saturation water is equal by bottom
Enter heat exchanging interlayer 7-0 after the 7-1 distribution of stream annulus；Bottom is flowed sets guiding device between annulus 7-1 and heat exchanging interlayer 7-0,
Such as orifice plate (or flow deflector form), circular hole is nearer from water inlet 1 in circumferencial direction non-uniform Distribution, and circular hole distribution is got over
Dredge, more remote from water inlet 1, circular hole distribution is closeer, and the saturation water ensured into heat exchanging interlayer 7-0 is uniformly distributed in circumferencial direction.
Saturation steam water interface by heat exchange flows up along heat exchanging interlayer 7-0, flows circle into top by top slit 7-3
Ring 7-2；Because the height of top slit is less than 10mm, now resistance hinders much larger than the part at saturation water out 9 at slit 7-3
Power, it is ensured that heat transferring medium is uniformly through slit 7-3, so as to ensure uniformly dividing for whole heat-transfer surface inner periphery directional flow
Cloth.
Slit 7-3 height is less than 10mm in installation process, and the top edge of dividing plate sleeve 6 is periodicity semicircular structure, its
Purpose is that dividing plate sleeve 6 produces axial thermal expansion when working, and provides a surplus capacity for the axial expansion of dividing plate sleeve 6, simultaneously
Local resistance caused by periodicity semicircular indentations can avoid slit too small is excessive, and increases the power consumption of system circulation pump.
It is more than 2 that steam water interface, which exports 9 quantity, and steam water interface outlet 9 is distributed uniformly and circumferentially.Carbonated drink is mixed
Compound exports 9 mouth of pipe top edges and is highly less than the top edge 30~50mm of extreme lower position of dividing plate sleeve 6, steam water interface outlet
9 lower edges of mouth are highly higher than the 30~50mm of top of packed layer 5；When packed layer is space-time, it is only necessary to meet steam water interface outlet 9
Mouth of pipe top edge is highly less than the top edge 30~50mm of extreme lower position of dividing plate sleeve 6.The purpose for the arrangement is that carbonated drink is avoided to mix
When compound outlet 9 and slit 7-3 is closer to the distance, short circuit phenomenon is caused.
Embodiment 2
Such as Fig. 3-4, operation principle is same as Example 1, but rectangular teeth and three is respectively adopted in the top edge of dividing plate sleeve 6
Angular toothing, the using effect of different marginal textures are more or less the same, main to consider that scene is easy to process.
Embodiment 3
The present embodiment is a kind of deformation of embodiment 1, i.e.,：Packed layer 5 is not filled with thermal insulation medium, and now saturation water is by entering
Annulus 7-1 is flowed in the mouth of a river 1 into bottom, and saturation water enters heat exchanging interlayer 7-0, saturation after annulus 7-1 distribution is flowed by bottom
Steam water interface flows annulus 7-3 by the slit 7-2 between upper baffle plate sleeve 6 and upper flange into top, in gravity
Under effect, saturation water can first flow to packed layer 5 and be filled.
More than, preferred embodiment only of the present utility model, but the scope of protection of the utility model is not limited thereto, and is appointed
What those familiar with the art the change that can readily occur in or replaces in the technical scope that the utility model discloses
Change, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with claim
The protection domain defined is defined.
