Abstract
The present invention relates to a vortex cooling tower which belongs to the technical field of chemical engineering cooling. The cooling tower has no filling materials, and comprises dispersing pin wheels 3 or defogging pin wheels 5 overlapped by layers, and a liquid-spraying device 4 is clamped among the dispersing pin wheels 3 or the defogging pin wheels 5, wherein the pin wheels comprise needles 15 overlapped by layers in a radial shape and rotated to form rotational flow with uniform rotational velocity. The cooling tower increases the specific surface area and the uniform distribution degree of fluid beads by nozzle dispersion, rotational flow dispersion and the collision dispersion of the needles 15 to the fluid beads. The centripetal heat-transfer velocity of airflow is also increased by the rotational flow, and the heat radiation efficiency and the heat radiation strength are enhanced, so a heat radiation process is flat and radial. The pin wheels and a spraying layer can also be superposed, the crossflow cooling of the tower body 6 enables wind to enter with the aid of a wind deflector 7 by multiple layers on certain height, so that the temperature drop of the cooling tower is increased, and the occupation area of the cooling tower is greatly reduced. The cooling tower uses the defogging pin wheels 5 for centrifugal defogging, not only thoroughly completes water removal, but also allows the spraying nozzle to have a wide atomizing section.
Description
One, technical field
The invention belongs to chemical industry cooling technology field.
Two, background technology
That cooling tower now has is reverse-flow, cross-flow type, perverse and unreasonable manner stream are hybrid, the branch of ejection-type, and what have is gravity-flow ventilation, and what have is force ventilation.Force ventilation has exhausting formula and blowing-type.These type of skills and the structure thereof of cooling tower are very ripe, and a nearly century is one one-tenth not change almost.The cooling tower temperature drop is generally about 5 ℃ under common its standard condition of exhausting formula glass fibre reinforced plastics cooling tower.Large-scale hyperbola wind cylinder type cooling stack, temperature drop is generally about 7 ℃ under its standard condition.The wind cylinder type cooling stack constitutes the important cost of large scale industry investments such as steam power plant.Exploitation heat conduction efficiency height, the cooling technology that temperature drop is big are thick-and-thin themes.
It is filler that the existing cooling tower technology that obtains extensive use all be unable to do without liquid distribution.The section of filler, arranged form are rather various, and Shen Qing cooling technology patent concentrates on this part mostly recently.Filler is to realize heat conducting by the globule that disperses on the vertical thickness to fall.Under the same water distribution intensity, can only realize bigger temperature drop by the thickness that increases packing layer.Filler accounts for cooling tower overwhelming majority volume, constitutes the main resistance of cooling tower simultaneously.The thickness of filler is limited, water distribution is confined to certain plane, thereby have only the treating capacity that could improve cooling tower by the area of section that increases cooling tower, and promptly the treating capacity of the floor space of cooling tower and cooling tower is directly proportional, and this is to cause cooling tower to become the basic reason of huge monster.
The function of filler is broken, dispersing liquid, increases liquid pearl and cold air surface contact area.Filler is a kind of means for influencing that dabbles.The globule diameter that obtains by dabbling have more several millimeters big, the specific area of liquid pearl is very little, heat exchange area is little, so the radiating efficiency of filling cooling tower is not high.
On the other hand, filler also is a heat-conduction medium, its absorb after heat and the relative temperature difference of the globule between surperficial very little, the amount of thermal conduction that can produce is little, is very easy to reach hot conductive equilibrium again.In the cooling tower body, have for 5% cool time at least, the liquid pearl of dispersion directly contacts quite a few surface area with filler, and can not contact with cold wind.Thus, filler is the major reason that reduces heat conduction velocity and intensity simultaneously.
The wall stream of filling cooling tower is inevitably, and wall stream is one of factor that reduces cooling effect without dispersion and directly dirty.
The uniformity coefficient of filling cooling tower water distribution is in various degree existing problems also, so, in filling cooling tower, be provided with and rely on hydraulic pressure rotation water injector.The rotation water spray can bring the hollow problem again, and hollow makes the short circuit of part air-flow, also is one of factor that reduces cooling effect.
The another one problem of cooling tower is moisture loss or the problem that dewaters.At first, the technology that dewaters rests on swash plate, the graticule mesh one class static component all the time, and is not progressive.Use such de-watering apparatus, cooling tower still has the moisture loss more than 0.3%.
If the ejection-type cooling tower, the globule that forms in the tower body is more tiny, and existing swash plate, the graticule mesh technology that dewaters is not competent, and moisture loss is just bigger.
The forced ventilation cooling is beneficial to the temperature drop that increases cooling tower, but air blast is if make the air-flow rate of climb excessive, water smoke, and particularly tiny water smoke can be taken out of cooling tower, forms water loss.So,, can not use too big cold blast rate again even the ejection-type cooling tower should be selected the suitable nozzle in aperture usually.The liquid pearl diameter of nozzle ejection is big, and specific area is little, and heat exchange area is little, and radiating efficiency is not high.
Three, summary of the invention

After cold wind enters in the tower body 6, adopt rotor that air-flow is rotated by the 15 radial arrangements of pin seedling in tower body 6 lower central.On rotor top, settle liquid-jet device 4 spraying liquids of little hole nozzle or atomizer again with a cover.Whereabouts or up liquid pearl are handed over rotation cold wind air-flow and mix, and the liquid pearl obtains centrifugal force and moves to limit portion when obtaining dispelling the heat.Behind the bigger descending arrival rotor of whereabouts liquid pearl,, obtain also moving behind the centrifugal force to limit portion with the broken dispersion in 15 collision backs of rotor pin seedling.Liquid is finished heat radiation under the superposition that disperse at nozzle dispersion, eddy flow, 15 fragmentations of pin seedling disperses three kinds of effects, and then compiles in limit portion, bottom.This anabolic process can repeat superposition and carry out.
Then,, once more air-flow is rotated, force up tiny liquid pearl to do centrifugal motion, dirty compiling behind the wall of arrival limit, finish dewatering or demist with the rotor of an other cover by the 15 radial arrangements of pin seedling on liquid-jet device 4 tops.
At last, in tower body 6 top exhausting or adopt air duct 13 air draughts, efflux thermal current in atmosphere or change recycling residual heat over to.
Technical scheme two of the present invention is a kind of eddy flow cooling means, is used for liquid cools.It is characterized in that, in same tower body 6, finish following process successively:
At first, in tower body 6 central upper portion and flow to wind and/or periphery crossing current air intake, perhaps directly on tower body 6 tops or quadrature or eccentric quadrature air blast.
Cold wind can adopt the rotor by the 15 radial arrangements of pin seedling that air-flow is rotated in tower body 6 central upper portion after entering in the tower body 6.This step can omit.
Secondly, settle liquid-jet device 4 spraying liquids of little hole nozzle or atomizer with a cover.Whereabouts or descending liquid pearl are handed over rotation cold wind air-flow and mix, and the liquid pearl is tentatively dispelled the heat.Then, in liquid-jet device 4 bottoms, air-flow is rotated with the rotor of a cover by the 15 radial arrangements of pin seedling, force descending tiny liquid pearl to do centrifugal motion, behind the bigger descending arrival rotor of whereabouts liquid pearl, broken with rotor pin seedling 15 collision backs, obtain also moving behind the centrifugal force to limit portion.Dirty compiling behind the wall of liquid pearl arrival limit.Disperse in nozzle dispersion, eddy flow, liquid is finished heat radiation under the broken superposition that disperses three kinds of effects of pin seedling 15, and then in the bottom, limit portion compiles, and finishes dewatering or demist.This anabolic process can repeat superposition and carry out.
At last, at tower body 6 downdrafts or adopt air duct 13 indirect air draughts, efflux thermal current in atmosphere or change recycling residual heat over to.
Technical scheme three of the present invention is eddy flow cooling towers, is used for liquid cools.It includes a tower body 6, transmission device 1, liquid-jet device 4.Tower body 6 is garden cylindricality or doliform or other surface of revolution shape or polygon or combination shape, tower body 6 outer walls or be added with rib or ring.Collecting-tank is arranged at tower body 6 bottoms, connects drainpipe at the bottom of the pond.Transmission device 1 comprises axle, bearing, bearing housing, motor.Motor directly is connected by shaft coupling with axle, perhaps by drive, band or chain or gearbox or frequency converter connection.
Eddy flow cooling tower of the present invention is characterised in that:
1, it contains at least one demist pinwheel 5 rotors, and/or at least one is disperseed pinwheel 3 rotors.
Pinwheel is encircled on certain diameter by wire or nonmetal wire pin seedling 15 and is symmetrical radial distribution week and plants seedling or hang seedling, divide stacking putting to combine.Pin seedling 15 cross sections can be garden shape or other shape, can extend by uiform section, can extend by variable cross-section.Pinwheel can be that the even radially dense arrangement of U font pin seedling 15 hangs on the locating ring 16, the locating ring 16 that hangs up properly pin seedling 15 adds stacking the putting through key plate 21 and circlip 18 of spacer ring 17, backing plate 22, pressing plate 20 minutes and is combined in pattern on the wheel hub 19, and promptly patent " is used for the pinwheel that thing is separated " (ZL 982019991.2).
Disperse the function of pinwheel 3 to be: at first, the broken liquid pearl of direct collision; Secondly, the pinwheel rotation produces eddy flow, and eddy flow produces following effect.
A, the length of motion route of prolongation hydrothermal solution pearl in tower body 6.
B, further atomizing, the dispersion globule increase the specific area of liquid pearl.
C, on microcosmic, rotation makes cold airflow hoop flow velocity increase several times, can in time carry out the thermally conductive gas circulation moves, make near the liquid bead surface steam pressure remain on low-level on, its thermal gradient then remains on the higher value, so heat conducting speed greatly improves, the heat dissipation capacity of unit interval is that specific heat load significantly improves, and the utilization rate of cold airflow significantly improves.
D, on macroscopic view, eddy flow forms the significant heat of radial direction and shifts, and improves the hot conduction conditions of macroscopic view in the tower body 6.Air humidity is big, greatly then its unit weight is little for temperature.When the eddy flow centrifugal motion, finish the little air-flow of unit weight that absorbs heat and absorb water vapour and tend to do entad diffusion, cold airflow then remains on the periphery or does centrifugal diffusion, makes the hot background value in peripheral certain zone remain on floor level, becomes to be the high efficiency and heat radiation district in the tower.The angular speed of eddy flow field suitably increases, and just reaches the center total gas pressure greater than peripheral total gas pressure easily, and pressure differential reaches significant degree, and the entad diffusion of thermal current just can take place.It converges mutually with the thermal diffusion of the short transverse that suction or air blast produce, and makes entad deflection of thermal diffusion direction vector, and actual thermal diffusion path is deflection entad just.So, on the very big one section height of cooling tower body 6 inner peripheral, all may carry out high efficiency and heat radiation.This is the tradition that the cooling procedure complanation arranges of changing over, and to the important thermokinetics foundation of high development.
The function of demist pinwheel 5 is: force the tiny liquid pearl of flowing to outlet to do centrifugal motion, compile dirty behind the wall of arrival limit; Movement clearance between the pin seedling 15 makes the liquid pearl see through along with rotation probability reduces, and the dynamic filtration effect is arranged again.Two kinds of effects combine to finish and dewater or demist.
2, transmission device 1 can have only one, perhaps is fixed on lower bracket 8, perhaps is fixed on top tower body 6; Also can there be two, respectively be fixed with a cover in the upper and lower part.Power transmission shaft can be cantilevered axle, can be two end bearings constraint up and down.Pinwheel can be connected on the same axis, also can connect respectively or be connected on two axles.On the power transmission shaft exhausting impeller 2 can be arranged.
3, liquid-jet device 4 is placed in and disperses pinwheel 3 or demist pinwheel 5 certain distance before, perhaps stretches between the gap of a plurality of pinwheels.Liquid-jet device 4 can be made up of linearity or ring-type dispersing nozzle radial or tree-shaped or multi-layer piping and some.The emission direction of liquid-jet device 4 nozzles and air-flow ascent direction can be and stream, can be counter-current relationship, also can be oblique.Be suitable for during oblique with the pinwheel direction of rotation and coordinate.The nozzle spray orifice should be less than 5mm.

When 5, being periphery crossing current air intake, tower body 6 peripheries are suitable for tangential wind deflector 7, and wind deflector 7 can be the shutter form.Wind deflector 7 can encircle all gardens shapes and arrange, also can be divided into 7 groups of plane wind deflectors and arrange by polygon ring week.Wind deflector 7 wants acute angle to intersect with the rotor direction of rotation, guarantees the coordination of air intake and rotation.
The function of wind deflector 7 is both to have guaranteed air intake, prevents that again cooling water from hitting wall and flowing out outside the tower body 6.Outside wind deflector 7, can hang filter screen.
6, tower body 6 lower central can settle be used for air intake or air draft shutter repeatedly a watt formula cover hydrophone 11.Covering hydrophone 11 outlines can be taper type, also can be pyramid.Certain zone, center can be opened wide.Tile 23 can be a taper type, also can be straight sheet.Between the tile 23 certain interval is arranged, strut with bar or sheet mutually.Cover on the inner edge that hydrophone 11 is buckled in tower body 6 collecting-tanks.
7, when not having mechanical ventilator or exhaust outlet 12 and crossing current air inlet too near, there is the enlarging air duct 13 of certain altitude directly or indirectly to be connected with tower body 6 apart from the tower body upper end.Air duct 13 shape freedom, more excellent with taper and surface of revolution shape.
In the technical scheme three, disperse pinwheel 3 and liquid-jet device 4 can match that branch is stacking to be put.The cross-flow type air inlet also can be corresponding to disperseing pinwheel multilayer setting in 3 fens.
When air inlet was provided with wind deflector 7 crossing current air intakes, pinwheel can produce some blast, and technical scheme three can be without force ventilation.
Technical scheme three has noise problem because adopt rotor.The noise of exhausting impeller 2 can drop to below the 60dB (A) at present at present.The pin seedling 15 of needle rotor can crooked, swing, and the dynamically balanced ability of self-control is arranged, and the dynamic balancing rank is than exhausting impeller 2 height.The noise of rotor generation can not be higher than 60dB (A) in principle.But the eddy flow that the rotation of needle rotor produces and the coordination degree of tower body 6 structures can produce whistle.So when the maximum line velocity that disperses pinwheel 3 or demist pinwheel 5 reaches 10m/s when above, in order to reduce noise, technical scheme three need make every effort to make rotor and tower body 6 inwalls that the big axiality of trying one's best is arranged.The pipeline office of liquid-jet device 4 puts and will make every effort to symmetry.
Technical scheme four of the present invention is combined type eddy flow cooling towers, is used for liquid cools.It includes a tower body 6, tower body 6 is garden cylindricality or doliform or other surface of revolution shape or polygon or combination shape, tower body 6 outer walls or be added with rib or ring, adverse current air inlet or crossing current air inlet or two kinds of air inlets and deposit are arranged, unified collecting-tank is arranged at tower body 6 bottoms, and collecting-tank connects at least one discharge outlet 9.Transmission device 1 comprises axle, bearing, bearing housing, motor.Motor directly is connected by shaft coupling with axle, perhaps by drive, band or chain or gearbox or frequency converter connection.
