Abstract
The utility model discloses a liquid nozzle in order to solve the problem that the existing liquid nozzle has the disadvantages of smaller spraying area, lower liquid flux, complex structure and greater manufacturing difficulty. The liquid nozzle of the utility model comprises a feeding pipe (3) and a shell (5), wherein a cylindrical inner cavity (2) is formed in the shell (5); a tangential channel (4) is formed in the tangential direction of the cylindrical inner cavity (2) between the feeding pipe (3) and the cylindrical inner cavity (2); and outlets (1) shaped like a wide-angle trumpet are formed at two ends of the cylindrical inner cavity (2). The liquid nozzle of the utility model is applicable in mass-transferring gas and liquid in packed towers and spraying hollow towers in petrochemical enterprises and also applicable to the devices for the desulfurization and dust removal of exhaust gas and other devices for the dust removal of other gases in petrochemical enterprises, thermal power plants and other enterprises.
Description
Technical field
The utility model relates to a kind of liquid or be used for the fluid jetting head of dedusting of being used to distribute.
Background technology
Be used for occasions such as the packed tower of gas-liquid mass transfer and hollow-spraying-tower at petrochemical enterprise, need to use fluid jetting head distribution liquid; The desulfurating dust removing device for flue gas of petrochemical enterprise, steam power plant and other enterprise and other dedusting device also need to use the fluid jetting head spraying liquid to carry out dedusting.The disclosed conical hollow nozzle of Chinese patent CN2631633Y comprises into water direction and the orthogonal volute nozzle body of water outlet direction.A radially side of nozzle body is with end cap seal, and opposite side connects nozzle.Be provided with in the body with the concentric tubular of nozzle in overlap, body and interior inner room also are provided with diaphragm.Liquid obtains certain centrifugal force in nozzle body, sprayed by nozzle.The disclosed swirl injection type liquid distribution trough of CN2250818Y is used for refining oil tower; Be provided with a rotational flow generator behind inducer, the rotational flow generator back is provided with hybrid chamber and shrinks an expanding conical nozzle.Rotational flow generator is a flow deflector, and flow deflector is provided with perforate.Feedstock oil enters rotational flow generator by inducer, through shunting and after hybrid chamber mixes, by shrinking expanding conical nozzle ejection.The disclosed Spray-nozzle for removing dust of CN2724848Y comprises outer nozzle and nozzle inner core, and the nozzle inner core is fixed in the outer nozzle, leaves the gap between the two.This gap is the press water passage; Current spray after herein, form taper open circles ring-type water curtain.The shortcoming that the aforesaid liquid shower nozzle exists is, liquid all is that spray area is less from side ejection, and liquid flux is also less.Structure is comparatively complicated in addition, and manufacture difficulty is bigger.
Summary of the invention
The purpose of this utility model provides a kind of fluid jetting head, to solve problems such as the existing existing spray area of fluid jetting head is less, liquid flux is less, structure is comparatively complicated, manufacture difficulty is bigger.
For addressing the above problem, the technical solution adopted in the utility model is: a kind of fluid jetting head, be provided with feed pipe, housing, be provided with cylindrical cavity in the housing, it is characterized in that: between feed pipe and the cylindrical cavity along cylindrical cavity tangentially be provided with tangential runner, the two ends of cylindrical cavity are provided with the wide-angle flaring exit.
Adopt the utility model, have following beneficial effect: (1) liquid (for example water) enters cylindrical cavity through feed pipe, tangential runner, in cylindrical cavity around axial rotational flow, last under action of centrifugal force by two wide-angle flaring exits ejections at cylindrical cavity two ends.From the very near distance of each wide-angle flaring exit, can respectively form a fluid curtain (having two) that is essentially the circular flat shape.Spray area is very big, and the area of each fluid curtain has 4～6 square metres (it is that several centimetres border circular areas is a hollow region that the center has only diameter) approximately, and liquid distribution gets very even.Owing to can form fluid curtain from the very near distance of each wide-angle flaring exit, thereby occupy-place of the present utility model height is just lower.Liquid can be from two wide-angle flaring exit ejections at cylindrical cavity two ends, and not only spray area is big, and liquid flux is also bigger.(2) the utility model is simple in structure, is easy to make; Can economical with materials, reduce cost.(3) do not have inner member in the cylindrical cavity, therefore pressure drop of the present utility model is low, and anti-blockage capability is strong.(4) the utility model operating flexibility is big, and liquid can both distribute very evenly in liquid load is 0.82～12.6 cubic metre/hour scope.
The occasion that the utility model is used to distribute liquid can obtain mass transfer effect preferably.The occasion that is used for dedusting, dusty gas from bottom to top by the formed two-layer fluid curtain of each fluid jetting head, have dust removing effects preferably in tower.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.The drawings and specific embodiments do not limit the claimed scope of the utility model.
Description of drawings
Fig. 1 is the structural representation of the utility model fluid jetting head.
The specific embodiment
Referring to Fig. 1, fluid jetting head of the present utility model is provided with feed pipe 3, housing 5, and housing 5 can be a shape such as square, cylindrical.Be provided with cylindrical cavity 2 in the housing 5, feed pipe 3 is generally vertical mutually with cylindrical cavity 2.Between feed pipe 3 and the cylindrical cavity 2 along cylindrical cavity 2 tangentially be provided with tangential runner 4, the two ends of cylindrical cavity 2 are provided with wide-angle flaring exit 1.
The diameter d of cylindrical cavity 2 is generally 10～60 millimeters, and the port diameter D of wide-angle flaring exit 1 is generally 40～100 millimeters.
During operation, liquid (for example water) enters cylindrical cavity 2 through feed pipe 3, tangential runner 4, in cylindrical cavity 2 around axial rotational flow, last under action of centrifugal force by two wide-angle flaring exits, 1 ejection at cylindrical cavity 2 two ends.From the very near distance of each wide-angle flaring exit 1 (normally 3～10 millimeters), each forms a fluid curtain (have two, figure slightly) that is essentially the circular flat shape; Fluid curtain is positioned on the horizontal plane.
The utility model is basically by the mode identical with existing fluid jetting head, and level is installed on the various towers (cylindrical cavity 2 and two wide-angle flaring exits 1 axially vertically).When being installed on the gas wash tower, can 1～5 layer of fluid jetting head of the present utility model be installed, evenly install 1～5 for every layer according to the requirement of tower diameter size and dust removing effects.
Be used for occasions such as the packed tower of gas-liquid mass transfer and hollow-spraying-tower at petrochemical enterprise, and the desulfurating dust removing device for flue gas of petrochemical enterprise, steam power plant and other enterprise and other dedusting device, the utility model can be adopted.
