Abstract
The invention belongs to the field of petrochemical equipment, and relates to an instrument for spraying materials, in particular to a nozzle of an atomizer. The nozzle comprises a ball joint and a flange. The lower end of the ball joint is welded in an inner hole of the flange. The ball joint comprises a straight cylinder portion and a hemispherical portion connected to the upper end of the straight cylinder, and a pressure gauge pipe orifice is welded at the connection of the straight cylinder portion and the hemispherical portion. The nozzle is characterized in that a tongue plate is arranged in a cavity of the ball joint, the upper end of the tongue plate is located in an arc spout formed at the top end of the hemispherical portion, and the end face of the outer side of the lower portion of the tongue plate contracts with the side wall of the cavity of the ball joint tightly. By using the nozzle, the sprayed materials can be distributed more evenly, and meanwhile, the pressure difference between fed materials and the sprayed materials is reduced.
Description
Technical field
The invention belongs to field of petrochemical industrial, relate to a kind of utensil for the material ejection, specifically a kind of shower nozzle of atomizer.
Background technology
At present, the charging ability is generally used at home at the nozzle of 20t/h in petrochemical industry catalytic cracking (FCC) device, but some is local or not fully up to expectations, material skewness, pressure reduction such as ejection change the problem that waits greatly, need thus the nozzle of this flow is improved, a thinking is to optimize the performance of nozzle by the internal structure that changes nozzle.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of shower nozzle of simple in structure, ingenious, rational atomizer is provided, use this nozzle to make the material pressure reduction of charging and ejection decrease simultaneously so that the material distribution of ejection is more even.
According to technical scheme provided by the invention: a kind of shower nozzle of atomizer, comprise bulb, flange, described bulb lower end is welded in the flange endoporus, described bulb comprises vertical tube part and is connected in the hemisphere portion of vertical tube part upper end, be characterised in that: in described bulb inner chamber, be provided with hyoplastron, hyoplastron upper end places in the arc spout that hemisphere portion top offers, and the outside, hyoplastron bottom end face fits tightly in the bulb intracavity sidewall.
As a further improvement on the present invention, described hyoplastron is welded on the vertical tube part.
As a further improvement on the present invention, described hyoplastron top is semicircle transition shape or is straight flange.
The present invention compared with prior art, advantage is: the present invention makes that by existing nozzle is carried out technological improvement its performance is optimized, use the present invention can be so that the material of ejection distributes more even, thereby better service is enhanced productivity in production, creates bigger value.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is A-A cutaway view among Fig. 1.
Fig. 4 is semicircle head dummy hyoplastron.
Fig. 5 is the straight flange hyoplastron.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
Shown in Fig. 1 ~ 5, comprise flange 1, bulb 2, vertical tube part 2-1, the 2-2 of hemisphere portion, hyoplastron 3, arc spout 4 etc.
Shown in Fig. 1 ~ 5, the present invention is a kind of shower nozzle of atomizer, comprise bulb 2, flange 1, described bulb 2 lower ends are welded in flange 1 endoporus, described bulb 2 comprises vertical tube part 2-1 and is connected in the 2-2 of hemisphere portion of vertical tube part 2-1 upper end, be provided with hyoplastron 3 in described bulb 2 inner chambers, hyoplastron 3 upper ends place in the arc spout 4 that hemisphere portion 2-2 top offers, and the outside, hyoplastron 3 bottoms end face fits tightly in bulb 2 intracavity sidewalls.
Described hyoplastron 3 is welded on the vertical tube part 2-1.
Described hyoplastron 3 tops are semicircle transition shape or are straight flange.
The present invention is arranged at the leading section of atomizer, feedstock oil enters from the mixing chamber side of atomizer, atomizing steam enters mixing chamber along axis, and the gas-liquid two-phase fluid in the hybrid chamber enters the helical duct of eddy current under the certain pressure effect, the fierce blending of circling round fast, viscosity and the surface tension of liquid are further descended, along with reducing of spin chamber's diameter, the corresponding increase of tangential velocity, liquid is the generate film under centrifugal action, with the effect of gas medium under realize broken atomizing.Use the atomizer of bulb of the present invention, atomizing effect is good, heavy oil feed can be atomized into the trickle droplet near catalyst particle size, is conducive to the gas-phase reaction of RFCC; Result of use is preferably arranged, use this device after, the green coke amount reduces, light oil yield increases, economic benefit obviously improves.
The present invention makes that by existing nozzle is carried out technological improvement its performance is optimized, use the present invention can so that the material of ejection distribute more even, thereby better service enhance productivity in production, create bigger value.
