Abstract
The utility model relates to a bubble atomizing nozzle. In the utility model, the inner wall of the middle part of an outer cavity is sagged inwards into a trapezoidal cavity. A spiral core (4) and an oil separating plate (2) are arranged in an inner cavity. The inner wall of the right part of the outer cavity is provided with a plurality of small holes. A ring cavity chamber is formed between the inner wall of the outer cavity and the spiral core. The spiral core and the right end of the outer cavity are formed in a taper shape, and an annular outlet is formed between the spiral core and the right end of the outer cavity. The left end of the spiral core is provided with a screw thread which is matched with the oil separating plate. The gas flows into the ring cavity chamber from small holes of the inner wall of the outer cavity, and the oil flows into the ring cavity chamber from the inner cavity through the spiral core and the oil separating holes of the oil separating plate. The oil contains lots of bubbles, the oil is spouted from a main outer, and the bubbles are blasted to cause the fuel oil to be atomized sufficiently.
Description
The utility model relates to a kind of effervescent atomizer, belongs to the technical field of combustion apparatus.
Liquid fuel is burnt effectively, it must be broken into droplet, just make its atomizing, the quality of its atomization quality, directly influential to its efficiency of combustion, mist is thin more, and it is also abundant more to burn.
At present, be extensive use of pressure atomized fog jet and pneumatic nozzle; Pressure atomized fog jet is to utilize the pressure of liquid self to make fuel atomization as kinetic energy, and simple in structure, cost is also low, and step-down influences greatly but its atomizing effect is loaded, and liquid mist penetration power is poor, and liquid droplet footpath liquid body viscosity influence is big; And pneumatic nozzle, though its atomization specific pressure atomizing is strong, the atomizing air consumption is big, and can't design the length of flame and flame cone angle, thereby significant limitation is arranged.
The purpose of this utility model is that a kind of effervescent atomization nozzle will be provided, it can overcome above-mentioned shortcoming, mainly utilize bubble as power, the bubble explosion produces very thin liquid mist, angle from the atomizing energy, also be the energy that has utilized Alevaire (air or steam) most effectively, so air consumption is little, makes gas liquid ratio be no more than 10%.
The purpose of this utility model is achieved in that
Nozzle has an exocoel and inner chamber, the outer cavity wall cross section cavity in echelon that caves inward at the middle part, oil dividing plate is positioned at this cavity, on the exocoel right part inwall aperture is arranged, be equipped with in the inner chamber and revolve core and oil dividing plate, outer cavity wall and revolve between core and to form the ring cavity chamber revolves the core right part and has formation one ring exit between the taper of taper and exocoel right-hand member, and revolving the core left end has the screw thread that matches with oil dividing plate.One circle is set on the oil dividing plate divides oilhole.
Fig. 1 is the schematic diagram of effervescent atomizer.
Now in conjunction with the accompanying drawings the structure of effervescent atomizer is described in detail:
By Fig. 1, nozzle has an exocoel (1) and an inner chamber (2), be equipped with one in the inner chamber (2) and revolve a core (4) and an oil dividing plate (3), it is one trapezoidal that the inwall of exocoel (1) inwardly is recessed at the middle part, oil dividing plate (3) is positioned at the space that this trapezoid cross section is formed, gas is flowed into by exocoel, oil flows into from inner chamber (2), exocoel right part inwall is provided with many apertures (5), gas hole (5) thus enters by outer cavity wall and revolves the ring cavity chamber (7) that core (4) is formed, and is injected in the oil, thereby flows to main loop outlet (6) before forming the air bubble-shaped flow direction, from this outlet ejection, the bubble explosion makes fuel oil be able to abundant atomizing.One circle is set on the oil dividing plate (3) divides oilhole (8),, can control oily flow by the aperture and the number change of minute oilhole; Ring exit (6) can be regulated its area size, revolve core (4) left end and be processed with the screw thread (9) that matches with oil dividing plate (3), rotation is revolved core (4) and is moved axially with regard to producing, and can regulate the area size of ring exit (1), thereby regulate atomization.This nozzle is applicable to metallurgy, the glass petrochemical industry, and the atomizing medium consumption is few, energy savings, improving environmental pollution all has good efficacy.
Compared with prior art, effervescent atomizer has following advantages:
1. atomizing particle is thin, and particle size distribution is even, and the atomizing medium consumption is few.
2. atomizing cone angle angular shape and length all can be regulated.
3. can realize the efficient stable burning.
Claims (2)
1, a kind of effervescent atomizer, it is characterized in that: nozzle has an exocoel (1) and inner chamber (2), exocoel (1) the inwall cross section cavity in echelon that caves inward at the middle part, oil dividing plate (3) is positioned at this cavity, on exocoel (1) the right part inwall aperture (5) is arranged, be equipped with in the inner chamber (2) and revolve core (4) and oil dividing plate (3), outer cavity wall and revolve between core (4) and to form ring cavity chamber (7), revolve core (4) right part and have and form a ring exit (6) between the taper of taper and exocoel (1) right-hand member, revolving core (4) left end has the screw thread (9) that matches with oil dividing plate (3).
2, nozzle according to claim 1 is characterized in that: a circle is set on the oil dividing plate (3) divides oilhole (8).
