Wherein above-mentioned installation step is one of method for optimizing in numerous methods, is not limitation ot it.
The using method of conical surface aerial fog nozzle that this of present embodiment do not stop up, do not have vapour lock is as follows:
At first, the conical surface aerial fog nozzle that assembles is installed in the pipeline on the corresponding flange, wherein water inlet, air inlet are corresponding one by one with delivery port, gas outlet on the corresponding flange, seal handle and get togather; After all nozzles all were in place, at first the opening conduits air-supplying valve was opened the water supply line water supply valve subsequently; Compressed air filters through air filter screen along air inlet, compile by the pure qi (oxygen) collecting tray, and carry out flow restriction by the tolerance metering hole, enter the annular gas tank of termination then along the axial air drain 365 on the water-in flange, enter in the sub-helicla flute of spiral by the air-vent on the nozzle base, and form swirling eddy along helicla flute; Cooling water is after water inlet enters nozzle, enter water purifying chamber through the water quality strainer filtering, enter the semi-transparent hole, center of the stifled flange of the conical surface through water yield metering hole, again through radially semi-transparent hole, conical surface tank, be evenly distributed to annular water tank, be subjected to the double action of interior water of annular water tank and rotary air, the rotation floating ring is suspended among the air water film, be subjected to swirling eddy to promote to do high speed rotary motion; Simultaneously compressed air is ejected into slit between the stifled and nozzle sleeve of the conical surface along slit between floating ring and nozzle sleeve, and moisture film is formed negative pressure, simultaneously the water that will rotate suck in the lump, mixed aerosol, spray with corresponding angle conical surface aerosol form along the stifled conical surface of the conical surface in the lump.
The conical surface aerial fog nozzle of present embodiment is applied to the cooling of Secondary Cooling Zone of Continuous Caster, because the conical surface aerial fog nozzle of present embodiment adopts water filter and air cleaner, therefore, its common maintenance can be in the method that guarantees to adopt under the no production prerequisite Hand scarf, need not unload nozzle, just after opening blowoff valve, open air feed or water supply valve, new water that enters or gas just can be gone out the impurity that exists impurity to accumulate the chamber from sewage draining exit, thereby aerial fog nozzle is carried out Hand scarf safeguard that its concrete steps see also aforementioned Hand scarf step.Certainly, if impurity is more in the fluid, or can not lean against line cleaning and deal with problems the time, also can unload the removal of contamination that disintegrates behind the whole aerial fog nozzle.
Conical surface aerial fog nozzle of the present utility model utilizes the conical surface stifled, rotation floating ring and triangular narrow the meeting of nozzle sleeve have constituted a jet ejectors, between the slit between the nozzle sleeve expansion conical surface and rotation floating ring, compressed air radially sprays along it, at the ring cap of rotation floating ring along locating under the impact of water at air of floating ring and conical surface caulking joint crack outflow, enter in narrow the meeting between the stifled and nozzle sleeve of the conical surface, and spray with taper surface along the narrow angle that meets, make floating ring and conical surface caulking joint crack form negative pressure simultaneously, avoided compressed air to the vapour lock that water forms, on same nozzle, made the air water mixed proportion realize regulated at will.
Because the rotation floating ring uses cleverly, the place ahead at the rotation floating ring, be subjected to the hole for water spraying hydraulic pressure effect of the stifled conical surface circle distribution of the conical surface, make between the stifled conical surface of the floating ring and the conical surface and form very thin water membrane, in being subjected to from helicla flute, the other direction of rotation floating ring rotates air effect, make floating ring be suspended in air and the moisture film intercropping is rotated at a high speed, mechanical mixture by means of the floating ring that rotates at a high speed, fragmentation, at the ring cap of floating ring along air water intersection, air is fully mixed and atomizing with water, and along the conical surface stifled with the nozzle sleeve expansion segment conical surface between the slit spray, thereby played the air water mixing, atomizing, the multiple effect of control spray angle.
Because the combination that nozzle base, water quality filter screen, air filter screen, pure qi (oxygen) collecting tray, water purifying chamber, impurity accumulate chamber, sewage draining exit, realized that water filtration, air filtration, water purification buffer memory, air buffer memory, impurity accumulate, regularly artificial blowdown, avoided phenomenon of blocking in the effective time.
After using conical surface aerial fog nozzle of the present utility model, no matter how the air water mixed proportion is adjusted, and air-resistance phenomenon all do not occur, its vaporization effect is good, spraying evenly, the strand cooling condition is significantly improved, constant product quality is improved significantly; On the basis of strengthening the water system purification filtering, adopt this patent nozzle to realize the continuous nonclogging good result of working more than 15 days simultaneously.
In sum, the conical surface aerial fog nozzle of difficult obstruction of the present utility model, no vapour lock has many advantages and practical value, and in like product, do not see have similar technological design to publish or use, really belong to innovation, it not only all has bigger improvement on design, function, have technically than much progress, guaranteeing to have very significantly effect on the high-quality level, thereby practical more, and have the extensive value of industry, become a new and innovative, progressive, practical new construction.
