Abstract
The invention discloses a double-Y type fuel treble atomization method and an atomizer thereof. The atomization method is as follows: high-speed vapor passes through an air inlet and is tangent with fuel oil sprayed out by an oil inlet nozzle at the horizontal direction, oil drops are atomized and mixed and then are tangent again with the high-speed vapor jetted out by an air inlet at the other horizontal direction so as to be atomized and mixed further, the mixture is jetted into a furnace by a pore of a mixing pore for carrying out atomization further. The atomizer comprises an oil-vapor transport segment (1) and an oil-vapor mixing segment (2), the oil inlet nozzle (4) and two air inlets are arranged in the oil-vapor transport segment, wherein, an included angle is formed between the air inlet (3) at the upper part and the oil inlet nozzle, the air inlet (5) at the lower part is in parallel with the oil inlet nozzle and arranged below the oil inlet nozzle (4), the air inlets at the upper part and the lower part are communicated, and a mixing chamber (6) arranged in the oil-vapor mixing segment is communicated with the air inlet below the oil-vapor transport segment. By the tangential force action of the double-Y type structural high-speed vapor and multiple atomization of the jet mixing of the trumpet pore of the oil-vapor mixing segment and the like, the particle sizes of the oil drops are thinner and can even be 30 Mum, thus improving the atomization efficiency.
Description
Technical field
The invention belongs to the improvement of petrochemical industry burner atomization technique, relate generally to a kind of double-Y shaped fuel treble atomizing method with and atomizer.
Background technology
In existing torch atomizer, it mainly acts on is atomized fuel oil, therefore, can be divided into Alevaire atomizing, mechanical atomization and combined atomizing three major types by its side's of atomizing method usually.Wherein, Y type oil burner atomizer atomization method has the extremely insider favor of following plurality of advantages because of it: regulate than big, general load can be adjusted to 25%, external some marine boiler, and when not controlling excess air, even up to 1:20; Compare with jumbo pressure atomization formula burner, do not need high-head oil pump, general oil pressure 7～21kg/cm
2, the about 10kg/cm of steam
2Exert oneself down any, atomization quality can both keep well, and during underload, atomization quality also improves to some extent; That single burner is exerted oneself is big (3000～7000kg/h), even reach (10000kg/h); Steam consumption quantity is little, generally has only 2% of fuel weight; Atomizing angle can both remain unchanged when any load, and also insensitive to the surface smoothness in hole, and oil droplet is even, and atomized particle size is thinner, even can reach 50 μ m; Adaptability to various liquid fuels is stronger; Operating period is longer.Yet, even if such one extremely everybody oil burner nozzle of favor still exist some problem and shortage because the atomization method of single Y type is adopted in fuel oil and air inlet, desirable not enough to the atomizing effect of fuel oil, nebulization efficiency is not high enough, causes the oil inflame after the atomizing abundant inadequately.Simultaneously the machining accuracy height and the steam vent that require of the atomizer shower nozzle of said structure is easily stifled, if with the faying face poor sealing of internal and external casing, oily amount of leakage is increased severely, even can reach 0.01 of boiler oil consumption.
Summary of the invention
The purpose of this invention is to provide a kind of double-Y shaped treble atomizing mist method with and atomizer, be further to improve the burner nebulization efficiency, reduce oil droplet size, fuel savings oil.
Purpose of the present invention can adopt following technical scheme to realize: described double-Y shaped fuel treble atomizing method is:, high velocity vapor is tangent by the fuel oil of inlet nozzle ejection by air admission hole same level direction, the oil droplet atomizing is mixed, then, tangent once more with the high velocity vapor that another horizontal direction air inlet is sprayed, further atomizing mixes, and mixture is sprayed onto in the stove through the aperture of mix aperture, do further atomizing, can fully burn through the oily particulate of treble atomizing.
Described double-Y shaped fuel treble atomizing device comprises oil gas transportation section and oil gas mixer two parts, inlet nozzle and two air admission holes are arranged on the oil gas transportation section, the air admission hole and the inlet nozzle of its middle and upper part have angle, the parallel below that is positioned at inlet nozzle of the air admission hole of bottom with inlet nozzle, the air admission hole on top communicates with the air admission hole of bottom; The hybrid chamber that is provided with in the oil gas mixer communicates with the air admission hole of bottom, oil gas transportation section.
The air admission hole on top, described oil gas transportation section and the angle of inlet nozzle are 45.
Fuel feed hole in the described inlet nozzle is the pyramidal structure of convergent.
Hybrid chamber central shaft in the described oil gas mixer is coaxial with the air admission hole of oil gas transportation section lower horizontal direction, and is horn-like, and the end port diameter that links to each other with air admission hole is less than port of export diameter.
The present invention has following characteristics:
1. described oil gas transportation section inlet nozzle and two air admission holes, the double-Y shaped structural relation of forming between them.
2. tangential force effect and the oil gas mixer bellmouth orifice hybrid chamber through double-Y shaped structure high-speed steam sprays multiple atomizings such as mixing, and oil droplet size is thinner, even can reach 30 μ m, thereby has improved nebulization efficiency;
3. tangential force effect and the oil gas mixer loudspeaker mixing lumen pore through double-Y shaped structure high-speed steam sprays multiple atomizings such as hybrid chamber, oil droplet size is thinner, under fixing and appropriate air-fuel ratio, the oil droplet specific area increases, it fully contacts with the definite oxygen of saying so of putting of air, burning is just more abundant, thereby has saved fuel oil;
4. the oil gun material therefor is common and cheap, gets final product with common bar Vehicle Processing.
5. long service life is changed convenient and swift.
