Description
Technical field
The utility model belongs to plant equipment field, relates to cleaning device, especially relates to a kind of air cooling heat radiator cleaning machine gas-liquid mixed shower nozzle.
Background technology
Shower nozzle, as the core component of cleaning device, can directly affect the mode of cleaning, and then the efficiency of impact cleaning.For the cleaning way of air cooling system, divide high pressure water washing and pressure-air to purge at present, shower nozzle is single track shower nozzle.
High pressure water washing is to have utilized high-pressure water jet to clean, high-pressure water jet refers to by high pressure water generating device water is forced into dozens of to more than thousands of atmospheric pressure, by thering is the injection apparatus in tiny aperture, be converted to trickle water jet at a high speed again, there is huge blow energy.Existing a kind of cavitating water jet more effective than Cleaning by High Pressure Water Jet, cavitating water jet is a kind of high-pressure water jet efficiently, it is the principle of having utilized cavitation phenomenon and these two natural phenomenas of cavitation corrosion phenomenon, by produce artificially many cavitys in water jet a fluid stream, utilize powerful impulsive force that cavity collapse produces to strengthen the action effect of jet.
From physics, know, cavitation phenomenon refers under temperature-resistant condition, if ignore capillary small effect while forming minute bubbles, liquid flows local absolute pressure while reducing to saturated vapour pressure under local temperature, the very little bubble (being commonly referred to gas core) that liquid internal contained originally will expand rapidly, at the inner cavity that contains steam or other gases that forms of liquid stream, thereby produce cavitation phenomenon.Cavitation corrosion refers to the cavity process of crumbling and fall and betides moment (Microsecond grade), thereby in part, produce high instantaneous pressure, when crumbling and fall, occur in solid table and when neighbouring, the repeated stock effect that the extremely high pressure that the cavity of constantly crumbling and fall in current produces causes, makes solid table and produces destruction.
Many places, China power station are larger in dust storm, dry cold, in the environment of water resources shortage., high pressure water washing, length consuming time, water consumption is large, is not suitable for Arid Area.The cleaning of air cooling heat radiator is subject to the restriction of water resource, but merely utilize pressure-air to purge, easily causes again secondary pollution, occurs the deficiency of airborne dust aspect.
For this reason, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of Water-saving rinsing nozzle [application number: CN201110360458.4], include nozzle and sprayer body, sprayer body is comprised of gas passage and fluid passage two parts, the cross-sectional area of gas passage is greater than the cross-sectional area of fluid passage, and gas passage and fluid passage are positioned on same center line.
Although such scheme has solved the problem of water saving in cleaning process, by the impulsive force of air-flow, improve cleaning efficiency simultaneously, but wherein or merely utilize gas shock power, easily cause dust to fly upward, because the easy dust deposit of air cooling heat radiator heat-transfer surface, foreign material adhere to, and this kind of method is also not suitable for.
Summary of the invention
The purpose of this utility model is for the problems referred to above, and a kind of water saving is provided, and cleaning efficiency is high and solve the air cooling heat radiator cleaning machine gas-liquid mixed shower nozzle of airborne dust problem.
For achieving the above object, the utility model has adopted following technical proposal: this air cooling heat radiator cleaning machine gas-liquid mixed shower nozzle, comprise sprayer body, one end at sprayer body is provided with nozzle, the center of described sprayer body has axially extended gas passage, at gas passage outer, is arranged with axially extended fluid passage, in the end of sprayer body, is provided with hybrid chamber, above-mentioned nozzle is arranged on hybrid chamber and with hybrid chamber and connects, and described gas passage and fluid passage all connect with hybrid chamber.Gas and liquid mix at hybrid chamber, from shower nozzle, penetrate, and make liquid dispersion become fine droplet with high velocity air, play the effect of atomization.
In above-mentioned air cooling heat radiator cleaning machine gas-liquid mixed shower nozzle, the cross section of described gas passage is rounded, and the cross section of described fluid passage is annular, and the center line of nozzle, gas passage and fluid passage overlaps.Liquid in centre by gas passage around, injection be gas interior, outside, gas pours and in liquid, is beneficial to mixing liquid.
In above-mentioned air cooling heat radiator cleaning machine gas-liquid mixed shower nozzle, between described gas passage and hybrid chamber, by tapered channel, be connected, be connected with the gas passage size of one end of described tapered channel is greater than the size of the one end that is connected with hybrid chamber.Tapered channel is concentrated gas and is produced larger pressure, thereby produces larger impulsive force in the moment of spraying.
In above-mentioned air cooling heat radiator cleaning machine gas-liquid mixed shower nozzle, between described fluid passage and hybrid chamber, by conical ring passage, be connected, be connected with the fluid passage size of one end of described conical ring passage is greater than the size of the one end that is connected with hybrid chamber.Conical ring passage and tapered channel are in the same center line, and conical ring passage is around tapered channel, and gas and liquid are pooled to hybrid chamber from small-bore.
In above-mentioned air cooling heat radiator cleaning machine gas-liquid mixed shower nozzle, described nozzle is the large taper type in inner little outer end.Make to spray area coverage larger.
In above-mentioned air cooling heat radiator cleaning machine gas-liquid mixed shower nozzle, curved of the outer end of described hybrid chamber, described nozzle is positioned on arcwall face.
The utility model has utilized cavitation and two kinds of natural phenomenas of cavitation corrosion, after air enters in water, can exist with the form of bubble, there is some we bubble that is invisible to the naked eye to be known as gas core, in the process of liquid ejection, the pressure that ejection starting stage gas core is subject in liquid is far longer than atmospheric pressure, the root phase of ejection is along with the pressure that gas core is subject in liquid constantly reduces, it is large that gas core constantly becomes, become visible bubble, the terminal stage of ejection, mixture atomization forms droplet, bubble is along with droplet arrives on dust and other impurity, bubble starts to crumble and fall, on bubble, there is microjet, because this process is extremely short, cleaned material is caused to great impulsive force, thereby be that cleaned material is broken from air cooling heat radiator effectively, strip down.
The utility model is the method around gases at high pressure with highly pressurised liquid, and gas is punched in liquid, makes to be full of gas core in liquid, and final atomization forms the droplet with gas core, forms microjet reach cleaning action by cavitation corrosion effect.Because of gas itself, also exist very large flushing action, and liquid is shared, can save water resource simultaneously, is applicable to air cooling heat radiator many places in the characteristic of lack of water environment.
Compared with prior art, the advantage of this air cooling heat radiator cleaning machine gas-liquid mixed shower nozzle is: reduced the consumption of water, water-saving and environmental protection; The final atomization of mixing jetting of gas and liquid forms the droplet with gas core, and cleaning efficiency is improved; The dust raising phenomenon that minimizing causes in cleaning process; Simple in structure, be easy to manufacture.
