Description
Technical field
The utility model relates to a kind of Ou Yelu furnace roof spray nozzle devices.
Background technique
The predecessor of Ou Yelu is that COREX furnace is moved from Baosteel Luojing to eight steel as state-of-the-art COREX in the world
After a series of process and technology innovation, has the technology features of itself, therefore COREX furnace is renamed as Ou Yelu.For
COREX top coal gas padding washing device and adjustable Venturi Scrubber are transformed into weight by the energy-saving and environment-friendly function of realization, Ou Yelu
Power dedusting and dry-dedusting system.Original COREX shaft furnace wet gas cleaning is replaced using dry method dust gas purification process
Technique, if meeting working of a furnace fluctuation, erects stock gas under the conditions of unusual service condition by 150~280 DEG C of range of shaft furnace furnace roof normal working temperature
Temperature can reach 600 DEG C, since dry method dust cloth bag can only adapt to 200 DEG C or so of working condition, otherwise just by scaling loss cloth bag
Or shorten the service life of bag filter, influence gas quality and the normal production of Ou Yelu.The technical side at Ou Yelu blow-on initial stage
Case is that water injector is installed at the top of shaft furnace, and since liquid water cannot be effectively atomized by the nozzle of water injector, inhomogeneous cooling is even,
Water is beaten causes furnace wall in shaft furnace to be bonded behind shaft furnace material top, material chilling, and furnace charge is bonded on furnace wall in shaft furnace, causes vertical furnace
Material decline is difficult, influences shaft furnace furnace condition anterograde.
Summary of the invention
The purpose of this utility model is to provide a kind of Ou Yelu furnace roof spray nozzle devices, are able to solve water injector atomization
Unevenly, the nozzle core of water injector does not have this technical problem of atomizing functions, it is ensured that the atomization of vertical furnace top spray water installations is equal
Even, the resistance to material of protection furnace roof prevents furnace charge bonding and bag-type dust equipment damage.
Purpose of the utility model is realized as follows: a kind of Ou Yelu furnace roof spray nozzle device, including nozzle core and
Nozzle housing is connected by internal screw thread with the nozzle core being fitted in nozzle housing in nozzle housing upper part inner peripheral of cylinder barrel shaped
It is connected together, external screw thread is set on nozzle housing outer wall, truncated cone-shaped sky is respectively set in nozzle housing bottom centre from top to bottom
Chamber and cylindrical hole for water spraying；Intake antrum, the lower part of intake antrum is arranged in nozzle core top in nozzle core cylinder in T shape
Four water outlet circular holes are set on four peripheral walls, circle ring chamber is constituted between nozzle core and nozzle housing, are discharged circular hole and circle ring chamber
It is connected, water chamber is set in nozzle core bottom, mutually closing separates between water chamber and the intake antrum, water chamber
Four intake chambers are arranged in a pair two-by-two on periphery wall, arrange wherein there are two intake chambers along the same radial direction of water chamber, separately
Tangential direction mutually opposing arrangement of two intake chambers along water chamber, the bottom surface of nozzle core and the truncated cone-shaped cavity top surface
Periphery is in contact.
The utility model can change existing shaft furnace furnace roof and fetch water the drawbacks of cannot being atomized, by improving nozzle core and spray
The structure of mouth shell, 4 water outlet circular holes that liquid is arranged by the middle and lower part of nozzle core, the liquid of high speed and high pressure rapidly enter spray
In the circle ring chamber that mouth core and nozzle housing are formed, liquid enters and rotated into intake chamber to be thrown away to periphery, is revolved by centrifugal force
Central cavity is gone to, rotation type atomization is further speeded up.When fluid flow very little, when centrifugal force is greater than surface tension of liquid, circle
A small amount of big drop that platform shape cavity edge is dished out, directly splits into drop at this time.When flow and revolving speed increase, liquid is drawn as counting
More Filamentous jet stream is measured, liquid stream is extremely unstable, and liquid leaves after truncated cone-shaped cavity certain distance due to the gas with surrounding
Rubbing action occurs and is separated into droplet.Here it is filiforms to isolate into drop.When revolving speed and flow increase again, brin is linked to be thin
Film, as liquid film extends to the outside into thinner liquid film, and with the gas of surrounding friction occurs for very high speed and separates atomization,
Drop is split by film-form.
The utility model has the feature that
1, atomizing particle it is very tiny, it is uniform, ensure evaporating completely.
2, atomised spray area coverage is big.The maximum atomization diameter of atomizer can be mixed with coal gas and more be filled up to 3um-4um
Point, be conducive to coal gas cooling tune amount, and in entire water variation range, atomizing particle is held essentially constant.
3, significant energy conservation, it can realize micro-atomizing under lower hydraulic condition.
4, ensure that bag filter plays peak efficiency.For bag filter, gas temperature is reduced in suitable model
Within enclosing, the dry method dust cloth bag service life is improved.
5, water adjusting range is little, adjusts the pressure of water, and spraying water can continuously adjust between design maximum flow and zero.
Such runoff investigation range can be conveniently adjusted amount of water sprayed by regulating system when production status is unstable, and whole
In a water variation range, atomizing particle is held essentially constant.
6, it is strong to flutter the ability of catching for coal gas, cools down high-efficient, and atomization grain is tiny, and the speed for leaving spray head is fast, apart from spray head 1.2M
Shi Yiran can reach 25-30m/s, and the water fog particle of such high speed makes significant component of coal gas by effective elastic collision
Agglomeration.
7, due to special design, using the speed difference that is formed with periphery coal gas and pressure difference in gasification furnace, realize coal gas and
Tiny droplet and vapor and the most effective mixing for reflecting agent, are the ideal choses of uniform decrease in temperature.
8, additional control system guarantees that gas outlet temperature maintains according to the amount of water sprayed of the variation automatic adjusting jet-gun of gas temperature
In appropriate range, control system is stable, reliable, accurate.
