Description

A kind of spray-propelling atomizer

The present invention is a kind of low pressure and mass flow, big gas liquid ratio fluid power mechanical draft that drives and the atomising device (B05B) that injection air inducing combines, and also is a kind of hydraulic, and belonging to jet does not have part.

" spray-propelling atomizer " that Chinese invention patent ZL90106170.0 provides obtained breakthrough in that the spraying exhausting is technical, obtained applying.But also there is following weak point: 1.. can not satisfy customer requirements in some application places gas-water ratio, need further to improve air quantity, 2.. spray flow is vorticity, and the center does not have spray, is unfavorable for the heat and mass of air-water two phase flow.3.. the oil lubrication rolling bearing that rotating mechanism adopts, and be subjected to the effect tumbler end of the axial lift that device itself produces and rapid wearing can't be satisfied the instructions for use in continuous operation over a long time and the various adverse circumstances, maintenance and maintenance capacity are big.4.. not enough at the horizontal range of some application places spray.

The objective of the invention is to improve at the problems referred to above, a kind of novel spray-propelling atomizer is provided, improving gas-water ratio, improve the spray form, to increase horizontal range, and the reliability, life-saving, minimizing maintenance and the maintenance load that improve long-time running.

The present invention constitutes as follows:

A kind of spray-propelling atomizer has feed liquor bindiny mechanism 17, atomizer 3, and fan blade 6 is characterized in that (A) establishes 1 to 2 hydroecium that is interconnected 1,5 vertically, each hydroecium surface symmetry is fixed two and above atomizer.Each shower nozzle water inlet pipe axis 2 is α with horizontal plane angle, and each nozzle-axis 4 is β with axial angle, and its α value is in 0～± 60 ° of scope, and the β value is in 0～± 60 ° of scope.The inlet opening face 16 of hydroecium links to each other with the tumbler 15 of feed liquor bindiny mechanism, and the not moving part 10 of this mechanism is connected with outside feed liquor house steward 11, at tumbler and 8,10 of moving parts dress bearing assembly not.(B) atomizer (operating) water nozzle 3.4 (see figure 5)s that adopt outer injection type shower nozzle 3 or multiple induced jet type swirling-flow atomizing nozzle (seeing Chinese patent ZL89104110.9) or do not overlap with injection.Bearing assembly contain water lubriucated bearing 7 and with the axial force compensating disc 9 of tumbler mechanical connection.

Embodiment 1, sees Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5

Outer injection type shower nozzle 3, see Fig. 5, following formation: have the cylindrical or conical thin-walled injection cover 3.1 of air admission hole 3.3 more than 1 of convergent-expansion type (operating) water nozzle 3.4 peripheral hardware reach, adopt 1 cylindrical injection cover herein, the air inlet fiaring cone 3.2 of cone-shaped inner hole is housed outside it.This nozzle assembly is fixed in the top of the spherical hydroecium 3.5 of thin-walled of perforate, and the water inlet pipe 3.6 that has a flange 3.7 is connected with spherical hydroecium 3.5 outer wall lower tangential.Current, suck air and mix the double effects of will be improved atomizing and injection air with spray when design parameter mate from injection cover air admission hole after the nozzle ejection forms the rotation spray at the hydroecium eddy flow.

The tumbler of feed liquor bindiny mechanism 17 is rotating shaft 15, its link to each other with the inlet opening face 16 of hydroecium 5 (being fabricated to one whole herein).Feed liquor bindiny mechanism not moving part means the base 10 of bearing block 8 and bottom.Dress water lubriucated bearing 7 between rotating shaft and bearing block, between it and rotating shaft for being slidingly matched.Axial force compensating disc 9 is housed between rotating shaft and base.Have limbers 12,14 in the rotating shaft; Had

water hole

19,18 on bearing block and the base.Compensating disc places the ring casing that is communicated with atmosphere in the base 10, and last plane has the concave surface 13 of pressurising effect below limbers 12, promptly be used for the spill complementary area of water storage.The feed liquor house steward is equipped with the water inlet jet nozzle 11 that is fixed in base.Rotating shaft is threaded with the rotating shaft direction of rotation is consistent with direction of rotation with compensating disc, to guarantee both locking in the rotation.When press water through water inlet nozzle 11 when entering because the injection negative pressure that water jet produces, the pressure in the ring casing is atmospheric pressure, and press water is arranged in the complementary area, so form pressure reduction, produce a downward active force and offset the axial climbing power that causes by static pressure, so greatly reduced end wear.When balancing force equated with lift, rotating shaft was operated in the liquid suspended state.Compensating disc also has the axial thrust effect.

Atomizer 3 places the top of fan blade 6, and 4 fan blades are fixed by bolts in the rotating shaft at feed liquor face 16 places., it is labeled as α a (see figure 4) β a (see figure 3), both be on the occasion of.

Embodiment 2 sees Fig. 6, Fig. 3, Fig. 4

Atomizer 3 places fan blade 6 belows, establishes a garden cylindricality hydroecium 5 vertically, and two atomizer 3e, the 3f of spray are downwards adorned every 180 ° of directions in this hydroecium surface.Wherein the α angle is labeled as-α e (see figure 4), is labeled as negative value because of α e down changes from horizontal plane.The β angle be labeled as β e on the occasion of, because of from axial down direction be initial line toward changeing (see figure 3) along the n direction, n is this device direction of rotation (see figure 2).Shower nozzle is sprayed downwards, the fan blade updraft, and embodiment 1 is identical under all the other structures.

Embodiment 3 sees Fig. 7, Fig. 8, Fig. 3, Fig. 4

Do not establish fan blade, establish the spherical hydroecium 1 in a garden vertically, two upwards atomization shower nozzle 3j, 3h are adorned every 180 ° of directions in the hydroecium surface, and β angle installation direction is opposite.Its α angle is labeled as α j (see figure 4), α j be on the occasion of.Its β angle be labeled as β j ,-β j (see figure 3).Its-β j represents that corner is that initial line is with just β j direction of rotation is opposite from axially going up direction.This installs two shower nozzles spraying thrust and cancels out each other, and only relies on both out-of-balance forces slowly to rotate, because centrifugal force is little, again because of α j value is bigger, therefore bigger horizontal range is arranged, and is applicable to the application places that requires the big carry of spray.

Techno-economic effect of the present invention:

The present invention is directed to the deficiencies in the prior art, on mechanism and structure, optimize comprehensively, reached Expected Results, increase Big exhausting amount has improved gas-water ratio, has improved atomizing effect and spray form, has strengthened the biography of biphase gas and liquid flow The hot mass transfer effect has improved the reliability of long-term work, has prolonged the life-span, has reduced maintenance work, and Realize far range spraying apparatus, satisfied the requirement of the equipment such as height, middle temperature spray cooling tower and sprinkling irrigation, cultivation. Experiment Show, when work water pressure is that 0.08～0.20Mpa timer flow reaches 10～80M³/ h, rotating speed are 226～400r/M, air quantity 18000～56000M³/ h, gas-water ratio 0.6～2.2, spray is dripped diameter and is obviously improved, spray height 2～6M, No hollow section, laterally range is 20～30 meters, and nozzle dynamic flow coefficient is greater than 1 during rotation. Intermitten service three months The time submerged bearing and rubbing surface do not have noticeable wear.
