Abstract

The utility model discloses a multiple internal swirling flow mixing atomized burner for the mixing and the atomizing of gas-liquid fuel and air or steam, belonging to the technical field of a burner. An atomizer in the burner comprises a swirling flow press cover, double swirlers, a pi-shaped plug, an adjusting ring, etc. A fuel inclined hole and a gas intake inclined hole are staggered on the double swirlers to make the fuel and the air confluence swirling flow merged and pneumatically atomized in the outlet of the atomizer. Atomization effect is obviously. The closure head of the utility model is of seriation, and can be disassembled and replaced to meet the practical requirements of use.

Description

Multiple internal swirl mixing atomized burner

The utility model relates to the industrial furnace burner technical field.

At present, domestic and international existing various burners, no matter be internal-mixing or exterior mixing, when being used for heavy oil, residual oil, coal pitch prill, water-coal-slurry and air or water vapour blending, atomizing, burning, its burning is insufficient, and effect is not satisfactory, and its main cause is, fuel and air or water vapour are failed abundant blending and atomizing before burning, so that fail the energy in the fuel is fully discharged during burning.

The purpose of this utility model provide a kind of make fuel and air in atomizer through repeatedly rotating blending, atomizing effect significantly repeatedly in eddy flow blending atomising burner.

For achieving the above object, the utility model adopts following design: the atomizer of this burner is by eddy flow gland, gland, double cyclones, π shape plug, chuck and adjustable ring constitute, be socketed with gland and eddy flow gland on double cyclones top, there are chuck, this chuck lower end screw thread to be connected with adjustable ring in the double cyclones bottom by thread connection, the top of this π shape plug places in the chuck, and its top connects with the double cyclones lower end.For making fuel and air or water vapour be able to abundant blending and atomizing, staggered a plurality of fuel inclined holes and the air inlet inclined hole of being provided with at the middle part of double cyclones, the fuel inclined hole evenly distributes on double cyclones, the inclined hole direction is identical, be the eddy flow state after making fuel by this inclined hole, then gas advances inclined hole and also evenly distributes on double cyclones, and the inclined hole direction is identical, also is the eddy flow state after making air or water vapour advance inclined hole by this gas.For improving atomizing effect, on the sidewall of eddy flow gland, also have a plurality of air inlet inclined holes, and evenly distribute, make air or water vapour be eddy flow state in the same way by this air inlet inclined hole.Be provided with the fuel inclined hole on the sidewall of π shape plug, there is air admission hole its lower end.Air is entered in the exocoel of atomizer by air admission hole, producing rotary air by the air inlet inclined hole on the double cyclones, enter in the inner chamber of double cyclones, owing to also have a plurality of air inlet inclined holes on the eddy flow gland, then the air in the exocoel is also by this air inlet inclined hole, in epicoele, produce the air of eddy flow, and fuel is entered in the lumen by π shape fuel inclined hole beyond the Great Wall, by the fuel inclined hole on the bispin stream, enter in the lumen of its upper end, make fuel form the eddy flow state, like this, converge pneumatic nebulization in the exit of atomizer by the air of inner chamber and the ejection of epicoele eddy flow and the fuel of lumen eddy flow ejection.Its air is identical with the fuel swirl direction, also can be anti-phase, and the fuel inclined hole on the double cyclones also can be straight hole, then Pen Chu fuel is non-eddy flow state, and air is the ejection of eddy flow state to export blending with fuel at atomizer, also can improve atomizing effect.

For making burner end socket slivering rowization and disassembling, assembling and replacing convenient, this end socket and outer tube adopt thread connection, for satisfying eject request to flame, squit hole on its end socket becomes following and distributes: a, circular uniform, b, Cheng Erhang or triplex row rectangle are uniform, c concentrates and is biased in a certain side, to satisfy actual instructions for use.

Compared with the prior art the utility model has the repeatedly eddy flow blending of fuel and air or water vapour, atomizing effect is remarkable, makes sufficient combustion, and advantage such as end socket seriation easy accessibility.

The utility model will be further described below in conjunction with accompanying drawing:

Fig. 1 is the utility model structural representation;

Fig. 2 is Fig. 1 schematic top plan view;

Fig. 3 is two row spray-hole end socket schematic diagrames;

Fig. 4 is biased in a side seal head schematic diagram for spray-hole;

Referring to accompanying drawing: atomizer is made of eddy flow gland 2, gland 3, double cyclones 4, π shape plug 5, chuck 6 and adjustable ring 7.Be socketed with gland 3 and eddy flow gland 2 on double cyclones 4 tops, this gland 3 and eddy flow gland 2 have chuck 6 in double cyclones 4 bottoms by thread connection for tight fit connects.There is adjustable ring 7 these chuck 6 lower ends by thread connection, regulate its ring 7, can change the air inflow of exocoel 10 and lumen 11, because exocoel 10 and lumen 11 communicate at air admission hole 9 places, then the part air enters lumen 11, carry out the part blending with fuel in the lumen 11.Air or water vapour enter inner chamber 14 by air admission hole 9 input exocoels 10 by the air inlet inclined hole 12 on the double cyclones 4, form the air or the water vapour of eddy flow state.Air or water vapour also enter air or the water vapour that epicoele 16 forms the eddy flow state by the air inlet inclined hole 15 on the eddy flow gland 2 in the exocoel 10, fuel is then by the fuel inclined hole 19 on the π shape plug 5, enter lumen 11, by lumen 11 by the fuel inclined hole 13 on the double cyclones 4 enter its upper end lumen in form the eddy flow state, then the fuel of eddy flow state and air export 17 places at atomizer and converge, the abundant blending of pneumatic nebulization, atomizing effect is remarkable, fuel after atomizing is by 18 ejections of the squit hole on the end socket 1.Be convenient to change for making end socket 1 seriation, this end socket 1 adopts thread connection with outer tube 8, according to instructions for use, 18 one-tenth following distributions of squit hole on its end socket 1: a, circular uniform (see figure 2), b, Cheng Erhang or the uniform (see figure 3) of triplex row rectangle, are concentrated and to be biased in a certain side (see figure 4) c.
