Abstract

The utility model relates to a liquid material atomizer. The left end of the outer shell of the spraying nozzle of the utility model is provided with a slant edge and a taper hole. A section of narrow transition holes is arranged on the right of the hole. A shrinkage taper hole and a circular hole are arranged on the right of the narrow transition holes. A rotational flow device and a spray head core are arranged in the hole. The left part of the core is provided with an expanding cone. The right part of the spray head core is C-shaped, the middle part of the spray head core is provided with an oil inlet hole, the right part of the spray head core is provided with an oil inlet pipe, and the cone at the left part is provided with an air inlet hole. The rotational flow device is provided with a splitter vane, a cone extends at the middle part towards the left, and a rotational flow grove is formed between the outer margin of the cone and the inner cone surface of the outer shell. A cavity between the rotational flow device and the spray head core is a mixing cavity. High-pressure gas and fuel oil are mixed to be foggy in the mixing cavity and are sprayed outwards. The high-pressure gas and the fuel oil can be sufficiently burnt in a furnace chamber. Combustion can be saved, and the spraying nozzle can not be clogged or coked.

Description

The liquid substance atomising device

The utility model relates to a kind of liquid substance atomising device, belongs to the skill territory of combustion apparatus.

Existing industrial furnace, for example glass-melting furnace, ceramic stove, metallurgical furnace kiln and petrochemical industry heating furnace, boiler or the like, its combustion apparatus all adopts atomizer, and is evenly mixed fuel oil and pressure-air (or steam), is that the molecule particle attenuates, atomisation is easy to igniting in burner hearth.The kind of atomizer is more, and its characteristics are respectively arranged.But major defect is that the nozzle of atomizer can't be the fine atomizing of liquid substance, and grain thickness and skewness make burning and insufficient so that wasted fuel oil, have gone back contaminated environment.Therefore, the essential structure of improving existing atomizer could be got rid of above-mentioned shortcoming.

The purpose of this utility model is that a kind of liquid substance atomising device will be provided, and it can overcome above-mentioned shortcoming.In the endoporus of nozzle housing cyclone is housed, fuel oil and gases at high pressure, are the evener distributions of refinement of particle of oil, thereby improve combustion efficiency after the effect of the splitter of cyclone strengthens its atomizing at mixed chamber mixing.

The purpose of this utility model is achieved in that

Nozzle housing (1) is similar to [a font, left end has slant edge (11) and taper hole (12), taper hole has one section narrower transition (13) to the right, be to the right one section inotropic taper hole (14) again, extend one section circular hole to the right, cyclone (3) and sprinkler core (8) are housed in the hole, sprinkler core (8) left part is the taper of expanding left, join with shell (1) inner wall sealing, and the sprinkler core right part is [a font; There is an axial fuel feed hole (9) at the middle part, and the right part cavity forms an oil inlet pipe (10), is provided with and axioversion air admission hole (6) at angle in the left part taper; Cyclone (3) right part is a dish type, splitter (4) is housed, the middle part is to the first from left cone, form an eddy flow groove (2) between the internal taper hole of its outer rim and shell (1), cavity is a mixed chamber (5) between cyclone (3) and the sprinkler core (8), forms an air inlet pipe (7) between sprinkler core (8) and the right endoporus of shell (1).

2. the middle part of sprinkler core (8) protrudes out a cone (15) left.

Now in conjunction with the accompanying drawings the structure of liquid substance atomising device is described in detail:

By Fig. 1. atomising device shell (1) is approximate [font, left end has slant edge (11), and taper hole (12) is arranged, one section narrower transitional pore (13) is arranged to the right, be to the right one section inotropic taper hole (14) again, extend one section long circular hole then to the right, cyclone (3) and sprinkler core (8) are housed in this hole, sprinkler core (8) left part is the taper of expanding left, join with the right inner wall sealing of shell, and right part is that [font, middle part have an axial fuel feed hole (9), the right part cavity forms an oil inlet pipe (10), is provided with and axioversion air admission hole (6) at angle in the left part taper; Cyclone (3) right part is a dish type, and splitter (4) is arranged, and a cone is extended at the middle part left; Form an eddy flow groove (2) between the conical surface of this cone outer rim and shell (1), cavity is a mixed chamber (5) between cyclone (3) and the sprinkler core (8), forms an air inlet pipe (7) between sprinkler core (8) and the right endoporus of shell (1).

By Fig. 2. Fig. 2. structure consistent with Fig. 1 basically, unique difference is that the middle part of sprinkler core (8) protrudes out a cone (15) left.Fluid class material enters mixed chamber (5) from fuel feed hole (9), air also enters mixed chamber (5) from the air admission hole (6) of air inlet pipe (7) simultaneously, the effect of the splitter (4) of process cyclone (3), the further pulverizing of oil molecule in the mixture attenuated, make mixed more even, become vaporific, by the taper hole (12) of eddy flow groove (2) and shell (1) outwards loss go out; If enter in the burner hearth of various industrial furnaces, make burning more complete, fuel is fully used, and is unlikely because incomplete combustion becomes waste gas and discharges, and therefore effectively saved the energy.

Compared with prior art, the structure of liquid material atomizer has following having a few:

1. atomization is good, and particle is thinner, distribution uniform.

2. cyclone is housed, makes flow rotation, strengthen atomizing.

3. the air consumption of atomizing is few, saves the atomizing energy.

4. flame holding is good.

5. the fuel flow amplitude of accommodation
