Abstract

The utility model discloses a centrifugal gas-liquid mixing nozzle, comprising a column-shaped nozzle body whose liquid inlet direction and liquid outlet direction are vertical to each other, and a cylindrical liquid inlet pipe connected on the nozzle body; a vortex chamber is arranged in the nozzle body. The utility model is characterized in that a liquid inlet cavity is arranged at the center of the liquid inlet pipe; at least a gas inlet hole which is used for gas feeding and is communicated with the liquid inlet cavity is arranged on the liquid inlet pipe wall; the diameter of the direct connecting segment between the liquid inlet cavity and the nozzle body vortex chamber is more than that of the inlet segment of the liquid inlet cavity; the gas inlet hole is arranged at the position where the diameter of the liquid inlet cavity changes. As the gas inlet hole is arranged on the liquid inlet pipe wall, when the pressure liquid flows through the hole, a negative pressure is formed, so that part of air is absorbed into the liquid inlet cavity and enters into the vortex chamber at the same time; the pressure liquid is communicated with air and fully mixed in the vortex chamber and then ejected after obtaining certain centrifugal force, so that the ejected liquid has high pressure to greatly enhance the applicability.

Description

A kind of centrifugal gas-liquid mix type nozzle
Technical field
The utility model relates to nozzle, is specifically related to a kind of environmental protection depositing dust, centrifugal gas-liquid mix type nozzle that atomizing effect is good of being used for.
Background technology
The rotarytype injector that is used for fields such as environmental protection sprinkling, dust pelletizing system in the prior art, its basic structure is referring to first page of disclosed data of Chinese patent 87204267 Granted publication specifications, and referring to Fig. 1, it is made up of access road (1), vortex chamber (2), spout (3), nozzle cover (4), the diameter of vortex chamber (2) is 5~6 times of nozzle diameter, and the diameter of spout (3) equals the diameter of access road (1).Current are entered in the vortex chamber (2) by access road (1) tangent line, and in the rotation of vortex chamber (2) high speed, its axial velocity and rotary speed increase simultaneously, after current are by the ejection of the spout (3) in the nozzle cover (4), at once to around disperse, form and spray cone, then division formation water smoke.What this nozzle adopted is to make the operation principle that atomizes again after the High-Pressure Water ejection, when existing input water flow pressure necessary enough (more than 3 handkerchiefs) in actual use, just can obtain atomizing effect preferably, and under low pressure performance is then bad.In addition, it is relatively poor for less relatively atomization of water current effect, and the fluid that is suitable for generally only limits to water, and can not be applicable to the fluid of other kinds.
The utility model content
At the existing above-mentioned technical deficiency of existing rotarytype injector, the purpose of this utility model is, ejection after a kind of gas-liquid mixed, more extensive, the better centrifugal gas-liquid mix type nozzle of atomizing effect of the scope of application are provided.
The technical scheme that the utility model is provided for achieving the above object is:
A kind of centrifugal gas-liquid mix type nozzle, it comprises feed liquor direction and the orthogonal cylindrical nozzle body of fluid direction, and be connected a cylindrical shape feed tube on this body, be provided with a vortex chamber in this body, it is characterized in that, described feed tube central authorities are provided with an admission chamber, are provided with an air admission hole that is used for air inlet and is communicated with described admission chamber on this feed liquor tube wall at least; The diameter of described admission chamber and the direct Connectivity Section of nozzle body vortex chamber is greater than the diameter of its entrance; Described air admission hole promptly is arranged on this admission chamber vary in diameter place.
Described centrifugal gas-liquid mix type nozzle is characterized in that, described nozzle body is made of a cylinder type shell and the nozzle cover that is arranged on this housing open front; Described enclosure interior central authorities also are provided with the coniform spiral core that a bottom is connected with this housing upper surface, the lower end is unsettled, and itself and inner walls form an annular clamping cavity.
Described centrifugal gas-liquid mix type nozzle is characterized in that the center of described nozzle cover is provided with a spout, and this spout is that big little, cross section outward is down trapezoidal cone shaped opening in one; Described coniform spiral core front end and this spout form a folder chamber of narrowing.
Described centrifugal gas-liquid mix type nozzle is characterized in that, the diameter of described spout outer openings is 0.5~1.5 times of described admission chamber diameter.
Described centrifugal gas-liquid mix type nozzle is characterized in that, the center of circle of described admission chamber is vertical mutually with the center of circle of described vortex chamber; Described admission chamber is to be connected the side of described nozzle body near its upper surface, and its admission chamber is connected with the tangential direction of vortex chamber along inner walls.
Described centrifugal gas-liquid mix type nozzle is characterized in that, described admission chamber vary in diameter place, symmetry be provided with two air admission holes.
Described centrifugal gas-liquid mix type nozzle is characterized in that, the diameter of described air admission hole is equal to or greater than the diameter of described admission chamber.
Advantage of the present utility model is: because the utility model is provided with an air admission hole that is used for air inlet and is communicated with described admission chamber on the feed liquor tube wall, when pressure fluid flows through this hole, form negative pressure at this place, the part air is inhaled in the admission chamber, and enters in the vortex chamber simultaneously; This pressure fluid is communicated with air and fully mixes in vortex chamber and obtain ejection again behind certain centrifugal force, thereby can make the liquid of ejection have elevated pressures, and simultaneously, its area coverage is strengthened; Also be applicable to simultaneously water, oil or other liquid, and the situation that pressure is little, flow is little, its applicability improved greatly.
Below in conjunction with drawings and Examples the utility model is further specified.
