Specific embodiment

Present invention will now be described in detail with reference to the accompanying drawings., the description of this part be only it is exemplary and explanatory, do not answer There is any restriction effect to protection scope of the present invention.

As shown in Fig. 1 to 5, one kind is high for viscosity, atomization difficulty is big, calorific value is high, water-soluble and non-water-soluble medium etc. The burner of burning, including straight-tube shape ontology 1, hot air inlet 7, atomizing steam entrance 3, high-boiling components entrance 2, level-one spray head 4, mist Change mixing chamber 5, second level spray head 8 and burner head 9, the radial communication of the hot air inlet 7 and the straight-tube shape ontology 1 is described The setting closed at one end of straight-tube shape ontology 1, the outlet of the level-one spray head 4 are set as circular, and axial direction is equipped with even number through-hole；Institute The sealed end that atomizing steam entrance 3 is stated across the straight-tube shape ontology 1 is connected to the through-hole, and the high-boiling components entrance 2 passes through The sealed end of the straight-tube shape ontology 1 is connected to the interior annular distance of the annulus；Described 5 one end of atomization mixing chamber and the level-one are sprayed First 4 outlet, the other end are connected to through the second level spray head 8 with the burner head 9, and the burner head 9 is located at the straight-tube shape At the open center of 1 other end of ontology.

1, level-one is atomized

Raw material (BDO high-boiling components) is connected by metal hose with high-boiling components entrance 2, after pump boosting into level-one The central tube of spray head 4 carries out current stabilization heat exchange in the duct, and then high speed high-boiling components stream enters atomization mixing by level-one spray head 4 Chamber 5；Atomizing steam is connected by metal hose with atomizing steam entrance 3, carries out the jacketed pipe of level-one spray head 4, in the duct Current stabilization heat exchange is carried out, the undergauge hole of level-one spray head 4 is then passed through, stream of emanating at a high speed is formed and enters atomization mixing chamber 5.

The steam jetting hole diameter of level-one spray head 4, overall aperture area are the one third of steam effective sectional area to two points One of between；Hole number is between 4-16 be 2 it is several again, be symmetric；The depth in hole is 2-4cm, 5-25 ° of the taper in hole Between.

2, atomization mixing chamber atomization

In atomization mixing chamber 5, high velocity vapor is emanated to flow and be contacted with high boiling logistics, and mass-and heat-transfer is carried out, and high-boiling components are steamed Steam fog is melted into droplet, and part droplet, which strikes, forms reflux on filler plate 51, is formed and is impacted with forward stream, is further broken Broken atomization；Another part droplet forms membrane on 51 surface of filler plate simultaneously, is threadingly advanced along helical form filler plate, or pass through 51 duct of filler plate enters next layer of filler plate, so propelled at high velocity forward, high-efficient atomizing is obtained, into second level spray head 8.

Being atomized 5 inner stuffing plate 51 of mixing chamber can be the atomization form of bio-carrier such as rotation shape steel wire, rotation shape steel band；Rotation angle Degree is between 45-60 DEG C.
