Description
Technical field
The present invention relates to flue gas defoaming technology, specifically refers to a kind of suitable for tower flue after wet flue gas dedusting or desulfurization
Or the froth breaker of the mechanism such as chimney, particularly relate to froth breaker shower nozzle.
Background technology
Recent domestic environmental requirement more and more higher, various furnace flue gas, petrochemical industry tail gas must be reached after removing dust desulfurization
Mark discharge.At present, the technique of wet dedusting desulfurization is still a kind of reliable prevailing technology, however, lime method conventional at present, stone
The flue gas discharged after the process of the wet dedusting desulfurizations such as limestone-based process, sodium alkali, Dual alkali, ammonia process, amine process, magnesium oxide method is containing wet
Or it is higher containing foam, emit white cigarette and conditions of streaking is serious.
In consideration of it, the applicant once developed a kind of froth breaker, referring to China Patent Publication No. 103170212A, for going
Except the bubble that may be carried after wet method flue gas dust-removing desulfurizing, and the mist produced because of bubbles burst is eliminated, emitted with reducing chimney
White cigarette and conditions of streaking.The Venturi tube upper end of the froth breaker, is designed with umbrella spray head(That is froth breaker shower nozzle)The umbrella of ejection
Shape water curtain is cleaned to the mist in flue gas so that in flue gas, bubble and mist are eliminated.Due to the text of this froth breaker
In venturi, air velocity is high, change big, affects the stability of umbrella water curtain;Mist in flue gas, bubble are carried out cleaning, disappeared
Except also requiring that umbrella water curtain has certain shock resistance kinetic energy;The lower edge of the umbrella water curtain that each froth breaker shower nozzle sprays should be located at
Outside Venturi tube diffuser upper end, and the scattering of umbrella water curtain can cause water circulation unbalance under working condition;In addition, froth breaking
Device shower nozzle will overcome blocking, reduce abrasion, quick-replaceable, improves life-span etc..
The content of the invention
The invention aims to overcome the shortcoming and defect that prior art is present, and provide a kind of umbrella water of ejection
Curtain form stable, and strong shock resistance, water curtain are difficult scattering, and the froth breaker shower nozzle that combination property is superior.
For achieving the above object, the technical scheme is that and be provided with described head body:First is cylindric interior
It is chamber, the axial inner ends positioned at the first cylindric inner chamber the rotation output cavity communicated with the first cylindric inner chamber, defeated positioned at rotating
The shower nozzle cavum laryngis for going out the axial outer end in chamber and communicating with rotation output cavity and the axial outer end positioned at shower nozzle cavum laryngis and shower nozzle
The umbrella water curtain forming cavity that cavum laryngis is communicated, the outer face of the described first cylindric inner chamber is inlet, umbrella water curtain forming cavity
Outer end be shield outlet, be fixedly installed spinning momentum kuppe in the described first cylindric inner chamber, the spinning momentum is led
Stream cover includes the circular cone plate and the laterally centered gear placed in the middle for being sealingly fastened in circular cone plate outer end of frustum
Plate, the inner of described circular cone plate are circumferentially sealingly fastened on the inner inwall of the first cylindric inner chamber, and the annular is bored
First cylindric inner chamber is separated into admission chamber and spin stabilization chamber by panel and baffle plate placed in the middle jointly, the outer end in spin stabilization chamber with
Rotation output cavity is connected, and the bottom in spin stabilization chamber is opened up on the outer end of described circular cone plate by guard seal placed in the middle
Have circular cone is distributed in connect a pair of spinning momentum holes of admission chamber and spin stabilization chamber, a pair of spinning momentum holes or so
It is centrosymmetric cooperation, and the centrage phase in two spinning momentum holes on plate and by axle of the centrage of the first cylindric inner chamber
Mutually parallel and perpendicular with the centrage of the first cylindric inner chamber, the circular cone plate is relative to spinning momentum hole place height position
The center of circle of the cross section put is not on the extended line of the centrage in spinning momentum hole.
By this setting, the operation principle and advantage of the present invention are:Liquid enters from inlet under pressure
Sap cavity, under the stop of the plate washer placed in the middle of spinning momentum kuppe and the compartmentation of circular cone plate outer wall so that admission chamber
In liquid there is higher pressure, additionally, due to offering to connect admission chamber and spin stabilization chamber on the circular cone plate
A pair of spinning momentum holes, and relative to spinning momentum hole place height and position cross section the center of circle not in spinning momentum hole
On the extended line of heart line, so that liquid is in rotation side when entering into the bottom in spin stabilization chamber by two spinning momentum holes
Formula, then expanded by spin stabilization chamber cone and design, the form for making the liquid stream in the spin stabilization chamber is along its spin stabilization
