Description
Technical field
The present invention relates to a kind of pulse water jet flow air suction atomization device, be particularly useful for the spraying of water jet.
Background technology
The range of application of spray technique widely, such as spraying, humidification, flue gas conditioning etc.Because existing atomizer, atomising device are in order to reach good atomizing effect, all need additionaling power (as water pump, blower fan etc.), what have also needs additional compressed air.Therefore the shortcoming that ubiquity energy consumption is high, complex structure, energy consumption are high.
Summary of the invention
Technical problem: the object of the invention is for problems of the prior art, provides the pulse water jet flow air suction atomization device that a kind of structure is simple, atomizing effect good, energy consumption is low.
Technical scheme: pulse water jet flow air suction atomization device of the present invention, comprise valve seat, it is bell-mouthed blind hole that the middle part of valve seat has aperture, the shower nozzle borded pile coordinating with its interior sidewall surface and form spiral flow channel is provided with in blind hole, the afterbody of shower nozzle borded pile be horn-like, with the horn mouth matched in clearance of blind hole, form annular jet; One sidewall of described valve seat is provided with the stepped intake tunnel of the resonance that is connected with the runner of shower nozzle borded pile, can produces, another sidewall is provided with the inlet channel be connected with the runner of shower nozzle borded pile, is connected with water supply connector in described intake tunnel entrance.
The spacing of described annular jet is 0.5-2mm; Described water supply connector is threaded with valve seat, and the front end of water supply connector is provided with preventing water leakage sealing ring; Described shower nozzle borded pile is threaded with valve seat, and the front end of shower nozzle borded pile is provided with leakage-proof water sealing ring.
Beneficial effect: the present invention utilizes the principle of self-vibration pulse water jet, the cavitation of fortified water jet and impact capacity under the same conditions, are the several times of common continuous water jet; And rely on the negative-pressure ward air of water jet to carry out mixing rear atomization.Can not have under the condition that additionaling power is very little, realizing atomization.Have structure simple, energy consumption is low, reliable, use cost is low, and atomizing effect is good, and energy-saving effect is obvious, has practicality widely.

Detailed description of the invention
Below in conjunction with accompanying drawing, one embodiment of the present of invention are described further:
Pulse water jet flow air suction atomization device of the present invention, is formed primarily of valve seat 1, water supply connector 2 and shower nozzle borded pile 3.The middle part of valve seat 1 has center ladder blind hole, the aperture of center ladder blind hole is horn mouth, the shower nozzle borded pile 3 coordinating with its interior sidewall surface and form spiral flow channel is provided with in the ladder blind hole of center, the afterbody of shower nozzle borded pile 3 be horn-like, with the horn mouth matched in clearance of center ladder blind hole, form annular jet 7, the spacing of annular jet 7 is 0.5-2mm.Shower nozzle borded pile 3 adopts helical groove structure, coordinates form spiral flow channel with valve seat 1 interior sidewall surface, guides gas-vapor mix.The sidewall of described valve seat 1 is respectively equipped with the intake tunnel be connected with the runner of shower nozzle borded pile 3 and inlet channel 4, the bottom that intake tunnel is stepped, be positioned at valve seat 1, inlet channel 4 is positioned at the top of side relative to intake tunnel, described intake tunnel porch is provided with water supply connector 2, intake tunnel outlet section is contraction mouth 6, outlet section to water supply connector 2 end face one section is the resonator 5 that current can be made to produce resonance, current can be made to produce and resonate and pulse.Water supply connector 2 and valve seat 1 are threaded connection, and seal with O RunddichtringO, and shower nozzle borded pile 3 and valve seat 1 are also threaded connection, and with the sealing of O RunddichtringO, in case leak-stopping water.
Operation principle: when current enter from water supply connector 2, when resonator 5 arrives the reducing 6 of receiving shower nozzle borded pile 3, due to the obstructive action of contraction front, will produce an initial pressure disturbance to current, this disturbance is reflected back toward resonator 5; When this pressure disturbance frequency is mated with the intrinsic frequency of resonator, the pressure oscillations then fed back will be amplified, thus fluid resonant is formed in resonator, make the eddy current in the water jet shear layer that ejects from contraction mouth become macrostructure separating cyclic eddy current, there is stronger cavitation and impact capacity.After current ejection contraction mouth 6 enters shower nozzle borded pile 3, along shower nozzle borded pile 3 fast to forward spin flow, and suck air from inlet channel 4.Due to the effect of gasifying and pulse, current mix with air fierceness, and eddy flow also stops by it to shower nozzle borded pile 3 top, finally spray from annular jet 7 with the form be atomized.
