Abstract
The invention relates to an ejector comprising a mixing chamber, a hollow throat and a diffusion tube, wherein the walls of the hollow throat and the diffusion tube are provided with tail suction holes to cause driving fluid to enter the ejector through the tail suction holes to form secondary ejection. A suction chamber and an ejector inlet are successively arranged on the upper face of the mixing chamber; and a nozzle is arranged between the suction chamber and the ejector inlet. The ejector of the invention utilizes differential pressure between working fluid and the driving fluid to enable the driving fluid to be subject to secondary ejection through the diffusion holes arranged on the hollow throat and the diffusion tube of the ejector. On the basis of not changing the other components of the ejector and maintaining the mass flow of the original driving fluid, the mass flow of the original driving fluid is increased through secondary ejection, thus the ejector coefficient of the ejector is increased, and the ejection performance is improved.
Description
Technical field
The present invention relates to a kind of sparger, be specifically related to a kind of sparger that utilizes the pressure reduction principle to improve jet coefficient.
Background technique
Sparger is a kind of jet turbulent fluctuation diffusion of utilizing, with high-pressure liquid injection low-pressure fluid and pass can mass transfer fluid machinery and mix reaction equipment.Have advantages such as simple in structure, easy processing, movement-less part, reliable operation, cost be low, convenient for installation and maintenance, and driven fluid there is not strict demand, also be suitable under particular job conditions such as especially strong, High Temperature High Pressure, demonstrate its unique advantages in toxic, radioactivity, inflammable and explosive, corrosivity.Therefore, be used widely in industries such as hydraulic and electric engineering, petrochemical industry, metallurgical light textile, nuclear energy uses, Aero-Space, farming and animal husbandries for a long time, and obtained huge economic benefit, development and national economy is played immeasurable effect.
The mass ratio of induced-to-inducing air of sparger is a key property index of weighing sparger.The size of mass ratio of induced-to-inducing air is being represented the quality of sparger jet performance.Mass ratio of induced-to-inducing air is big more, shows the working fluid of unit mass flow, and the mass flow rate of the driving fluid by sprayer pumps is big more.Mass ratio of induced-to-inducing air is numerically equal to the ratio of driving fluid mass flow rate and working fluid mass flow rate.Existing sparger mass ratio of induced-to-inducing air is little, and the jet performance of sparger is poor.
Summary of the invention
The present invention will propose a kind of sparger, this sparger does not need to change other members of existing sparger, and can also increase the mass ratio of induced-to-inducing air of sparger, have advantages such as simple in structure, easy processing, movement-less part, reliable operation, cost be low, convenient for installation and maintenance.
Technological scheme of the present invention is: a kind of sparger, comprise mixing chamber, and trunnion, diffusing tube is characterized in that: have the afterbody inlet hole on the tube wall of the tube wall of trunnion and diffusing tube, make driving fluid enter into sparger by the afterbody inlet hole and form secondary injection.Be provided with suction chamber above the mixing chamber successively, the sparger inlet; Be provided with nozzle between suction chamber and the sparger inlet.
Useful fruit of the present invention is: the present invention utilizes the pressure reduction of working fluid and driving fluid, makes driving fluid have the afterbody inlet hole from the trunnion of sparger and diffusing tube and is secondly ejected.Do not change the sparger miscellaneous part, do not reducing to have increased the mass flow rate of driving fluid by secondary injection, thereby increased the mass ratio of induced-to-inducing air of sparger on the basis of mass flow rate of original driving fluid, improving the jet performance of sparger.
Description of drawings
Fig. 1 is a section of structure of the present invention;
Fig. 2 is a plan view of the present invention;
Fig. 3 is that the present invention is at the schematic diagram that improves on the sparger mass ratio of induced-to-inducing air.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As Fig. 1, shown in 2, sparger of the present invention, it comprises sparger inlet 1, nozzle 2, trunnion 3, diffusing tube 4, suction chamber 5, mixing chamber 6, afterbody inlet hole 7.
On the tube wall of the tube wall of the trunnion 3 of sparger and diffusing tube 4, have afterbody inlet hole 7, make driving fluid enter into sparger and form secondary injection by the afterbody inlet hole 7 on trunnion 3 and the diffusing tube 4.
Be provided with suction chamber 5 above the mixing chamber 6 successively, sparger inlet 1; Be provided with nozzle 2 between suction chamber 5 and the sparger inlet 1.
The present invention is for the mass ratio of induced-to-inducing air that improves sparger, and improving injector performance has very significantly effect.The status parameter of the size of mass ratio of induced-to-inducing air and working fluid, driving fluid, the structure of sparger all has confidential relation.But experiment showed, the status parameter at working fluid, driving fluid, under other identical in structure situations of sparger, having mass ratio of induced-to-inducing air of the present invention will be much larger than the sparger of non-structure of the present invention.
As shown in Figure 3, be wet vapor 10 at working fluid, when being supercooled water 11, uses driving fluid the present invention.Supercooled water 11 is except entering sparger from suction chamber 5, and also the afterbody inlet hole 7 on trunnion 3 and the diffusing tube 4 enters into sparger.In this process, the present invention is except guaranteeing that supercooled water 11 can enter into the sparger from original suction chamber 5, also opened up trunnion 3 and diffusing tube 4 enter sparger as supercooled water 11 passage in addition, increased the mass flow rate of supercooled water 11 thus greatly, the mass ratio of induced-to-inducing air of sparger is increased greatly, improved the jet performance of sparger.
