Technical field
The present invention relates to a kind of for will be wherein at least one fluid be mixed into by the method in the main flow of conduit wall limited boundary by a plurality of fluids that chemicals forms at least in part.
The present invention also relates to will be wherein at least second fluid be mixed into by the mixing apparatus in the main flow of conduit wall limited boundary by each nozzle with nozzle opening by at least one first fluid and at least one second fluid that chemicals forms at least in part, especially for the mixing apparatus of the described method of execution.
Background technology
When making fibrous suspension, day by day use chemicals, described chemicals to affect energetically manufacture process and/or the quality of web of fiber.Chemicals mainly is fixative or retention agents.When being incorporated into fluid in the main flow, particularly in the web of fiber suspension that flows, existing basic problem is mixing as well as possible.At this, degree of mixing is also relevant with the chemicals demand.
For minimizing the use of chemicals, be devoted to for a long time to improve and mixed, but this so far may be fully dissatisfied yet.At this, problem is the deposition in spraying into the zone particularly.
Summary of the invention
Therefore, technical problem to be solved by this invention is to guarantee chemicals mixing as far as possible completely in main flow in the situation of avoiding depositing.
According to the present invention, this technical problem is solving aspect the method in the following way: so that first fluid was injected in the main flow before second fluid on the flow direction of main flow at least in part, and so that the position that second fluid enters in the main flow enters into position in the main flow further from conduit wall than first fluid.Ground is injected in the main flow because the second fluid that is preferably formed by chemicals at least in part and conduit wall have distance, thus this spray into regional in and on conduit wall, suppressed deposition.In addition, this has also supported mixing, removes from the edge of main flow because mix.
In addition, the mixed flow that produces after first fluid is injected to main flow is at the flow direction upper deflecting of main flow, and therefore wraps up in around Flow in Nozzle at least, flows and also wrap up in as much as possible around second fluid nozzle opening ground, and this has also prevented deposition.In addition, wrap up in and when second fluid nozzle opening mobile protected chemicals escapeing in the main flow, be not subjected to strong load.Consequently two fluids mix with the strong of main flow.
In by the situation for the manufacture of the formed main flow of fibrous suspension of paper web, board web, tissue webs or other web of fiber, the present invention provides special advantage aspect mixing.
Advantageously also by the application in the formed main flow of process water, fresh water or analog.
At this, the fluid of sneaking into can be formed by chemicals, fibrous suspension or water, wherein depends on type and the effect of chemicals, and described fluid of sneaking into also can be sneaked into fibrous suspension or water in advance.
If should will be injected in the main flow by the formed other fluid except second fluid of chemicals at least in part and mix, then advantageously first fluid had been injected in the main flow before other fluid on the flow direction of main flow at least in part, and the in-position of other fluid in main flow than the in-position of first fluid in main flow further from conduit wall.This causes obvious simplification, because supported simultaneously the mixing of second fluid and other fluid at this first fluid.
Aspect the type and effect of the chemicals of fluid, advantageously the nozzle opening of second fluid and other fluid is arranged on the flow direction of main flow side by side.According to mixability and the eddy current degree of hope, the in-position of this fluid in main flow can have identical or different distances apart from conduit wall.The nozzle opening of second fluid and other fluid apart from the distance of conduit wall the cross-sectional dimension of 5 millimeters and main flow 10% between.
Certainly, also can have advantageous is that the in-position of second fluid has surrounded the in-position of other fluid or has been used for the nozzle of other fluid.In the first situation, the in-position of fluid is arranged side by side, and in other situation, the in-position of other fluid is of living in more farther than the in-position of second fluid in main flow.
For supporting mixing of fluid and main flow with stronger eddy current, fluid or should become with the flow direction of main flow angle between 10 ° to 170 °, preferably become the angle between 70 ° to 110 ° to be injected in the main flow from the spray nozzle that nozzle sends.
Aspect mixing apparatus, the nozzle of crucial is second fluid extend in the main flow from conduit wall by the nozzle opening of first fluid.Consequently first fluid and main flow form mixed flow, and described mixed flow is to wrap up in around the second fluid Flow in Nozzle and as far as possible also to wrap up in around its nozzle opening and flow spraying into durection component on direction and the flow direction in main flow.This mixed flow prevented on conduit wall deposition and can be from spraying into that second fluid sends, and this external chemicals of having protected when being injected to chemicals in the main flow.This mixed flow has promoted the mixing of second fluid in main flow.
Be simplified construction, and also be the deposition on the nozzle of avoiding first fluid, the nozzle opening of first fluid is answered as close as possible conduit wall, forms the plane with described conduit wall as far as possible.
As previously mentioned, also can be injected in the main flow by the formed other fluid of chemicals at least in part.
At this, the nozzle of second fluid can advantageously be incorporated in the main flow by the nozzle opening that is used for different or identical fluid with the nozzle of first fluid.The nozzle opening of second fluid and first fluid is identical or different at this apart from the distance of conduit wall.
Also favourable structure is, the nozzle of the nozzle of second fluid and other fluid jointly extend in the main flow from conduit wall by the nozzle opening of first fluid.At this, the nozzle opening of the nozzle opening of second fluid and other fluid is arranged in juxtaposition with identical or different distances with the distance conduit wall on the flow direction of main flow.But also advantageously the nozzle opening of the nozzle of other fluid by second fluid extend in the main flow, and wherein nozzle opening has identical or different distances apart from conduit wall.
According to the requirement that mixes, type and the structure of conduit wall and the structure of channel cross-section of fluid, nozzle opening can have round or polygonal cross section.Nozzle also can be medially or is passed prejudicially nozzle opening.
Except the parameter of main flow, the effective range of spray nozzle depends basically on fluid pressure, bundle face and the variation of spray nozzle on its length at nozzle opening place.Lower fluid pressure causes the reduction of effective range in main flow of spray nozzle as the strong expansion of spray nozzle.This provides the possibility that affects the effective range of spray nozzle with the form of hope.
Especially, depend on the intensity of main flow, the flow direction of spray nozzle with respect to main flow can be tilted, preferably against this flow direction inclination or directed perpendicular to the flow direction of main flow.
For minimizing manufacturing cost, and also for finishing balanced flow behavior, advantageously make main flow by the conduit wall limited boundary have round, circular cross section particularly.
Certainly, in certain application, use the cross section of polygonal particularly rectangle.This boundary wall that also is applicable to especially to guide main flow is open situation upwards.
Description of drawings
Hereinafter explain in detail the present invention according to a plurality of embodiment.In the accompanying drawings, Fig. 1 to Fig. 4 schematically shows the cross section by different mixing apparatus.
The specific embodiment
Be used for a plurality of fluids 1,2,3,4 are mixed into the main flow 6 that comprises fibrous suspension at this illustrated mixing apparatus, described main flow 6 is directed in tubular passage for the manufacture of the flow box of the machine of the web of fiber of paper web particularly, and have 0.05% to 7.0% material density, particularly 0.2% to 2.5% material density.
Some fluids 2,3 are formed by the chemicals of retention agents particularly at least in part at this, for example polyacrylamide, polyvinyl lactam, polyethylene glycol oxide, fixative, or also formed by micron particles at least in part, for example bentonite or silicate.For avoiding the thermal shock of this chemicals when it sprays into, advantageously make its temperature consistent with the temperature of main flow 6, namely usually be heated.
At this, the completely effect of this chemicals also is mixed into by force precondition with fluid 2,3 in main flow 6.
But fluid 1,2,3,4 can also be formed by fibrous suspension or water (process water or fresh water) at least in part.If fluid 1,4 is fully formed by fibrous suspension or water, then described fluid is used for basically in main flow 6 interior formation turbulent flows, and if be water then for the dilution of main flow 6.
Certainly, also can make the fluid 1,2,3,4 that comprises fibrous suspension or water before spraying into main flow 6, sneak into chemicals.This premixed is possible sometimes, if without the in advance reaction of obvious chemicals or do not worry to cause thus deposition.Consequently also improved the mixability of corresponding chemicals in main flow 6.
In the mixing apparatus in the accompanying drawings, main flow 6 is by the passage guiding with annular cross section by boundary wall 5 limited boundaries.At this, be used for a plurality of mixing apparatus that fluid 1,2,3,4 is blended in the main flow 6 preferably can be evenly distributed in making progress in week of passage.
The structure of illustrated mixing apparatus is very simple in Fig. 1, and is basically formed by two nozzles 11,12, and described nozzle is injected to first fluid 1 and second fluid 2 flow direction 7 transverse to main flow 6 in the main flow 6.At this, second fluid 2 is partly formed by chemicals at least.At this, the nozzle opening 8 of crucial the is nozzle 11 of first fluid 1 is in the plane of conduit wall 5, and this has prevented from entering deposition in the zone at this of fluid 1.And the nozzle 12 of second fluid 2 medially the nozzle opening 8 of the nozzle 11 by first fluid 1 extend in the main flow 6.Therefore, the nozzle opening 9 of the nozzle 12 of second fluid 2 not only is in the main flow 6 relatively deeply, and relatively far away apart from conduit wall 5.Its advantage is obviously to cause deposition owing to the chemicals of second fluid 2 in the zone entering in main flow 6, but by the stretching out anti-here deposition in main flow 6.In addition, first fluid 1 be injected to main flow 6 formed when interior with main flow 6 on the flow direction 7 and transverse to the mixing of the component on the flow direction 7, so that nozzle 12 and wrapped up in around this mixed flow by the spray nozzle with second fluid 2 that nozzle 12 sends flows.This has also prevented deposition, has protected second fluid 2 when second fluid 2 escape to main flow 6, and causes two fluids 1,2 with the strong of main flow 6 but shielded the mixing.
In contrast, Fig. 2 shows mixing apparatus, and wherein second fluid 2 and other fluid 3 are formed by chemicals at least in part, and also is injected in the main flow 6 perpendicular to the flow direction 7 of main flow 6.Two fluids 2,3 spray into by nozzle 12,13 and undertaken, described nozzle 12,13 extend in the main flow 6 by conduit wall 5.At this, nozzle 12,13 guides by the nozzle opening 8 in the plane that is in conduit wall 5,15 respectively according to the described principle of Fig. 1.First fluid 1 arrives in the main flow 6 by the nozzle 11 with nozzle opening 8, and other fluid 4 is injected in the main flow 6 by the nozzle 14 with nozzle opening 15.
Consequently, first fluid 1 is wrapped up in around second fluid 2 and is flowed when spraying into, and the 4th fluid 4 is wrapped up in around the 3rd fluid 3 mobile.
For example, at this nozzle 12,13 nozzle opening 9,16 identical apart from conduit wall 5 distances.Addedly, also have the separates walls 10 that reaches in the main flow 6 between nozzle 11,14 nozzle opening 8,15, this has prevented this nozzle 11, two fluids 1 of 14,4 immediately mixing.
In Fig. 3 in the illustrated structure, second fluid 2 and with nozzle opening 8 guiding of the common nozzle 11 of the nozzle 12 of the other fluid 3 of at least one chemicals, 13 by being used for first fluid 1.Correspondingly, by enter at first fluid 1 main flow 6 when interior formed mixed flow wrap up in around two nozzles 12,13 and flow with two fluids 2,3 spray nozzle.At this, nozzle 13 stretches out farther in main flow 6 than other nozzle 12, and this can cause other eddy current and promote mixing.
Mixing apparatus according to Fig. 4 is mixed into three fluids 1,2,3 in the main flow 6 perpendicular to flow direction 7.At this, feature is that the nozzle opening 8 of nozzle 12 by the nozzle 11 of first fluid 1 of second fluid 2 extend in the main flow 6, and the nozzle opening 9 of the nozzle 13 of the 3rd fluid 3 by the nozzle 12 of second fluid 2 extend in the main flow 6.At this, the nozzle opening 16 of the nozzle 3 of the 3rd fluid 3 than the nozzle opening 9 of the nozzle 12 of second fluid 2 further from conduit wall 5.Thus, having produced second fluid 2 is wrapped up in by first fluid 1 when spraying into and streams moving and the 3rd fluid 3 is streamed moving by wrapping up in of second fluid 2 when spraying into.
Wrap up in to stream and moving especially protected the very long long-chain chemicals of chain, because this chemicals is being injected to main flow 6 and is subject to damaging when interior the strong load of its constitute and function.
By with this attainable strong and shielded mixing, can minimize significantly the chemicals demand.
For at the sufficient spray nozzle of main flow 6 interior formation, fluid 1,2,3,4 should be injected in the main flow 6 with the existing pressure between 1.5 to 10 bar in main flow 6 places.
The present invention has realized effectively sneaking into of a plurality of chemicals and has mixed, even there is very high quantity ratio between chemicals and the main flow.
