Description
technical field:
The present invention relates to a kind of atomizing nozzle, be specifically related to the two medium atomization nozzles used in evaporative cooler in a kind of converter dry dust collecting process, particularly relate to two medium atomization nozzles of a kind of ultrasonic assistant atomization.
background technology:
During converter steelmaking is produced, converter gas dry dedusting technology because it is energy-conservation, water saving and the high feature of efficiency of dust collection, be more and more applied in actual production, be acknowledged as developing direction from now on.Evaporative cooler is the key equipment in dry-dedusting system, mainly lowers the temperature to flue gas, the process of modified and thick dedusting, and it is particularly important to whole dust removal process to control its exit gas temperature well.If evaporative cooler exit gas temperature is too high, then dust specific resistance raises, and is unfavorable for dedusting; If evaporative cooler exit gas temperature is too low, then while trapping crude particle dust, easily produce the wet end, wall cling phenomenon, increase evaporative cooler ash-transmission system maintenance, converter producing is affected time serious, and the too low flue gas of temperature enters electrostatic precipitator can cause condensation, condensation housing will be caused to corrode or high pressure creepage.
The process of lowering the temperature mainly is realized by the evaporation endothermic of atomized water.Atomization be by liquid by nozzle ejection in gaseous media, make it to disperse and be broken into the process of small-particle drop.Because liquid phase is for the high-speed motion of air or gas, or due to the applying of mechanical energy and the rotation of jet apparatus or vibration, liquid can be atomized into the fine particle of various size scope.
Described nozzle is divided into atomizing nozzle and two medium atomization nozzle by constitutional features, known is be made up of inside and outside two-layer passage for the two medium atomization nozzles in evaporative cooler, water coolant is sprayed by inner-layer channel, water vapor, from the outer layer channel gap ejection being looped around nozzle central authorities, makes water coolant be atomized.
Ultrasonic atomizatio utilizes ultrasonic energy to make liquid form the process of fine mist in the gas phase, namely produces ultrasonic wave at the fluid surface of vibration, and the peak that shakes be made up of amplitude is separated drop fragmentation from surface.Along with ultrasonic frequency increases, atomizing droplet is more and more thinner, generally under hyperacoustic vibrational frequency effect, can obtain fine drop.Ultrasonic atomizer is divided into two large classes: fluid-dynamic type and electroacoustic transduction type.
The defect of said nozzle is: known limits by its structure and water quality for the two medium atomization nozzles in evaporative cooler in converter dry dust collecting process, and atomizing nozzle easily blocks, and affects production efficiency.
summary of the invention:
In order to solve the problem of the easy blockage phenomenon of the atomization nozzle of evaporative cooler in converter current dry dedusting technology, the invention provides two medium atomization nozzles of a kind of ultrasonic assistant atomization, this nozzle can realize uniform atomizing, drop finer atomization degree is high, simultaneously can prevent latch up phenomenon from occurring, can effective use for a long time.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of two medium atomization nozzles of ultrasonic assistant atomization, comprise nozzle body, also comprise piezoelectric ultrasonic transducer, described nozzle body is provided with water-in, inlet mouth, first jet mouth and fluid chamber, nozzle body top is buckled with cap of spraying nozzle, described piezoelectric ultrasonic transducer is fixed on fluid chamber bottom center, and described first jet mouth communicates with fluid chamber.
As preferably, described nozzle body and cap of spraying nozzle are threaded connection.
As preferably, nozzle body top macropore arranges internal thread, is connected with the outside screw on cap of spraying nozzle, and after nozzle body is connected with cap of spraying nozzle, circularize gap in first jet mouth profile, this annulus is second nozzle mouth.
As preferably, first jet mouth is arranged with second nozzle mouth is concentric.
As preferably, described inlet mouth communicates with second nozzle mouth, and high pressure steam sprays from second nozzle mouth.
As preferably, described water-in communicates with fluid chamber, and water sprays from first jet mouth.
Adopt technique scheme, compared with prior art, PZT (piezoelectric transducer) is placed in the central part in nozzle liquid chamber by the present invention, piezoelectric ultrasonic transducer produces ultrasonic wave, cavatition is produced to the water in fluid chamber, the impurity that hyperacoustic oscillation action also prevent in water simultaneously accumulates in fluid chamber, and the impurity in anti-sealing accumulates in nozzle inner walls, avoids the phenomenon of spray nozzle clogging to occur.Ultrasonic wave can make the water in fluid chamber produce cavitation phenomenon, and assisted atomization, the water after cavitation sprays from the first spout.High pressure steam sprays from the second spout, clashes into liquid film, makes liquid sheet breakup.PZT (piezoelectric transducer) produce ultrasonic wave can refinement drop atomization fineness, uniform atomizing, make atomization evenly.For in the evaporative cooler in converter dry dust collecting process, the phenomenon that can effectively prevent nozzle from blocking because water quality is bad occurs, and ensures that converter dry dust removal process is smooth, Effec-tive Function.
