Abstract

The utility model relates to an LY type oil nozzle, which comprises an oil pipe, a steam pipe, an oil nozzle head, a nozzle head, a blast cap, etc. The utility model is characterized in that a firs time oil and steam mixing chamber in a cylindrical shape is arranged before an oil outlet of the oil nozzle head; walls of the cylinder are provided with a plurality of first time steam inlet holes; the nozzle head is provided with a plurality of second time mixing holes, first time mixing jet holes, and second time steam jet holes; the second time mixing holes, the first time mixing jet holes, and the second time steam jet holes are crossed in a Y-shaped form; the outer wall of a jet outlet of each second-time mixing hole presents a conical protruding shape. The oil nozzle of the utility model has the advantages that the structure is simple; the requirement of oil cleanness is not high; the utility model is non-coking; the utility model is suitable for large and small oil jetting places; the utility model can be used for industrial furnaces using various fuel oils (such as heavy oil, residual oil, etc.), particularly glass melting furnaces.

Description

A kind of LY type atomizer

The utility model relates to a kind of LY type atomizer, belongs to fluid fuel burner class.

Present domestic known Y type atomizer, be by a plurality of aperture oil spouts, have advantages such as atomization quality is good, the adjusting ratio is big, air consumption is low, distributive value is big, but exist the easy coking of jet, the bad phenomenon of smoldering of atomizing under unexpected instantaneous excessive oil spout situation, influence product quality, and only be adapted to big distributive value (more than the 300Kg/h), the susceptible to plugging defective of jet during little distributive value.

It is better that the purpose of this utility model aims to provide a kind of atomization quality, overcomes the easy coking of jet, also can stablize oil spout under big or small distributive value and unexpected instantaneous oil spout situation, the prominent novel atomizer that sprays the phenomenon of smoldering do not occur.

The utility model comprises steam pipe (1), oil pipe (2), oil nozzle (3), blast cap (4), nozzle head (7), one of its feature is the oily vapour mixing drum that the outer cone front portion of the oily ejiction opening (11) of oil nozzle (3) is provided with a cylinder type, and outside this oil vapour mixing drum and oily ejiction opening (11), having several admission openings (5) on the barrel of junction, tapering, oily vapour mixing drum and nozzle head (7) cover press-fit the back and constitute once oily vapour mixing chamber (6); Two of its feature is to be provided with several mixed once spray orifices (9), secondary mix aperture (8), secondary vapour spray orifice (10) on nozzle head (7), the three is " Y " type and intersects, the outer wall of each secondary mix aperture (8) ejiction opening all is conical and protrudes, mixed once spray orifice (9) is opened in the inner chamber circle wall and the end face junction of nozzle head (7), and is evenly distributed.

Its concrete assembling is: steam pipe (1) is sleeved on oil pipe (2) and locates, oil nozzle (3) is screwed onto on the oil pipe (2), burner head (7) is sleeved on the oil nozzle (3), blast cap (4) is sleeved on the nozzle head (7), by blast cap (4) and being spirally connected of steam pipe (1) oil nozzle (3), nozzle head (7), blast cap (4) is pressed together.

The utility model is simple in structure, atomization quality good,, noncoking less demanding to the cleanliness factor of oil, the Alevaire consumption is low, use cost is low, be adapted to big or small distributive value place, can use particularly various glass-melting furnaces for the industrial furnace of various fuel oil (as heavy oil, residual oil etc.).

Accompanying drawing is a structural representation of the present utility model.

With reference to accompanying drawing, the technical performance of this utility model is described.(1), steam pipe (2), oil pipe (3), oil nozzle (4), blast cap (5), admission opening (6), oily vapour mixing chamber (7), nozzle head (8), secondary mix aperture (9), mixed once spray orifice (10), secondary vapour spray orifice (11), oily ejiction opening among the figure.

When oil with certain pressure during from the ejection of the oily ejiction opening (11) of oil nozzle (3), run into high pressure vapour collision the carrying out mixed aerosol of spirt from an admission opening (5), form once oily vapour mixture, once oily then vapour mixture is disperseed to go up several set mixed once spray orifice (9) ejections from nozzle head (7), enter secondary mix aperture (8) and with the collision of the secondary high-pressure vapour phase that from secondary vapour spray orifice (10), gushes out, carry out the secondary mixed aerosol, be atomized into thin elaioleucite, the spout through secondary mix aperture (8) front sprays into burner hearth.

In sum, set up the mixed once atomising device on the basis of the former Y type of the utility model atomizer, cushioned the speed that oily ejection burner directly enters burner hearth, make oily steam fog better quality, it is bad and smolder to have overcome under electric brake control atomizing under the instantaneous excessive oil spout state suddenly, influences the defective of product quality; Next is that the porous oil spout that the shunting before mixing by oily vapour changes in the past is the single hole oil spout, and atomizing and secondary mix aperture ejiction opening outer wall by the secondary mix aperture are the conical change of shape of protruding, reduce oil droplet and adhered to chance on the nozzle women's head-ornaments, make nozzle head be difficult for coking, so not only increased the oil spout impulse force but also prevented the obstruction of nozzle head under little distributive value situation.This oil nozzle can be made various ranks according to the size of distributive value.In addition, as long as change nozzle head, just can obtain various difform oil spraies, as flat mist, circle mist.

Claims

1, a kind of LY type atomizer comprises steam pipe (1), oil pipe (2), oil nozzle (3), blast cap (4), nozzle head (7), it is characterized in that the outer cone front portion of the oily ejiction opening (11) of oil nozzle (3) is provided with the oily vapour mixing drum of a cylinder type, and outside this oil vapour mixing drum and oily ejiction opening (11), having several admission openings (5) on the barrel of junction, tapering, oily vapour mixing drum and nozzle head (7) cover press-fit the back and constitute once oily vapour mixing chamber (6).

2, want 1 described LY type atomizer according to right, it is characterized in that nozzle head (7) is provided with several mixed once spray orifices (9), secondary mix aperture (8), secondary vapour spray orifice (10), the three is " Y " type and intersects, the outer wall of each secondary mix aperture (8) ejiction opening all is conical and protrudes, mixed once spray orifice (9) is opened in the inner chamber circle wall and the end face junction of nozzle head (7), and is evenly distributed.
