Abstract
A kind of new type nozzle of the present invention, belongs to industrial technical field.The technical problem to be solved by the present invention is to existing nozzle mass transfer effect is poor, and it is low to eventually lead to sulfur dioxide flue gas detersive efficiency.The technical scheme is that：A kind of new type nozzle, tangential liquid inlet, axial liquid inlet and flange by nozzle body and on nozzle body form, nozzle body is hollow oil tank shape, tangential liquid inlet pools mixing chamber with axial liquid inlet in nozzle body, nozzle body top is equipped with jet expansion, and flange is arranged in the lower end of nozzle body.The invention has the advantages that a kind of new type nozzle is simple in structure, by the perfect adaptation of rotating jet section and efficient mass transfer section " two-part ", flue gas washing efficiency is greatly improved.
Description
Technical field
The invention belongs to industrial technical fields, and in particular to a kind of new type nozzle.
Background technology
In the industrial processes such as oil refining, chemical industry and electric power, a large amount of sulfur dioxide flue gas are will produce.Using " washing
Liquid " is a kind of effective with flue gas adverse current " shock " and obtains widely applied wet desulphurization mode, wherein dynamic wave scrubbing
Technology is most representative.Eddy flow component is arranged in traditional washing nozzle inner wall, to realize that gas-liquid two-phase is hit, to realize
Efficient mass transfer, but when operating condition changes, since its inner eddy flow component form is fixed, the covering of jet expansion liquid stream
Face and momentum can not be adjusted accordingly, and to influence mass transfer effect, and it is low to eventually lead to sulfur dioxide flue gas detersive efficiency.
Invention content
In view of the above technical problems, the present invention provides a kind of new type nozzle, the new type nozzle by rotating jet section and
The perfect adaptation of efficient mass transfer section " two-part ", greatly improves detersive efficiency.
The present invention is achieved by the following technical programs：A kind of new type nozzle by nozzle body and is mounted on
Tangential liquid inlet, axial liquid inlet and flange composition, nozzle body on nozzle body are hollow oil tank shape, tangential liquid
Body entrance pools mixing chamber with axial liquid inlet in nozzle body, and nozzle body top is equipped with jet expansion, and flange is set
It sets in the lower end of nozzle body.
Further, the quantity of tangential liquid inlet is 2, and is vertically arranged along nozzle body.
Further, it is in half cone-shaped that the part in nozzle body is stretched into tangential liquid inlet.
Further, it is cylinder to stretch into the part in nozzle body for axial liquid inlet.
The invention has the advantages that a kind of new type nozzle is simple in structure, pass through rotating jet section and efficient mass transfer section
The perfect adaptation of " two-part " greatly improves flue gas washing efficiency.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment 1, referring to Fig. 1, a kind of new type nozzle of the present invention, by nozzle body 1 and on nozzle body
Tangential liquid inlet 10, axial liquid inlet 11 and flange 2 form, nozzle body 1 is hollow oil tank shape, and tangential liquid enters
Mouth 10 pools mixing chamber 12 with axial liquid inlet 11 in nozzle body, and 1 top of nozzle body is equipped with jet expansion 13, method
Orchid 2 is arranged in the lower end of nozzle body 1.
Further, the quantity of tangential liquid inlet is 2, and is vertically arranged along nozzle body.
Further, it is in half cone-shaped that the part in nozzle body 1 is stretched into tangential liquid inlet 11.
Further, the part that axial liquid inlet 11 is stretched into nozzle body 1 is cylinder.
The operation principle of the present invention：Heavy-oxygen-enriched water in dissolved oxygen case enters nozzle by centrifugal pump and forms stable rotating jet
Spraying into washer upwards, (liquid stream that wherein bottom enters, which provides, axially flows to Qz, and tangential entry then provides tangential flow Qy.Three strands
Liquid stream is formed " axial rotary stream is sprayed by spout " in mixing chamber, and increasing axial flow can be such that axial momentum increases, and increase is cut
The section coverage rate of cleaning solution can then be increased to flow), " head-on collision " is carried out with the air for entering washer from the top down, forms two
Phase mass-transfer zone greatly improves flue gas washing efficiency.
The present invention do not do illustrate be all made of the prior art.
It should be noted that herein, the terms "include", "comprise" or its any other variant are intended to non-row
His property includes, so that the process, method, article or equipment including a series of elements includes not only those elements, and
And further include other elements that are not explicitly listed, or further include for this process, method, article or equipment institute it is intrinsic
Element.In the absence of more restrictions.By sentence " including one ... the element limited, it is not excluded that including
There is also other identical elements in the process, method, article or equipment of the element ".
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
