Technical field:
The present invention relates to the efficient energy-saving device of rock gas, oil and heat transfer, mass transfer.The long distance conveying that this device can be widely used in rock gas and oil cuts down the consumption of energy, and also can be used for improving the efficient of heat transfer, mass transfer.
Background technique:
At present long to exist drag losses apart from transport gas and oil big, and the drawback that energy consumption is high, recent research show, adopt stream of pulses can reduce the drag losses of natural gas transport greatly.Utility model patent number is 89201391.5, its invention and created name is that " rock bit oscillation pulsed water jet nozzle " this nozzle is made up of upper and lower two nozzle bodies, the top nozzle body is made up of flow-guiding mouth, top nozzle, chamber three parts, the profile of top nozzle body is a ladder cylindrical body, mouth body inner flow passage is made up of two index curved surfaces and three cylndrical surface, the top of following nozzle body is a curved surface Rotary-table, low profile is that ladder is cylindrical, jump ring is installed in its smallest cylinder surface, and the inner flow passage of following nozzle body is a cylindrical hole.
Summary of the invention:
The present invention provides a kind of pipe pulse stream generator according to the principle of background technique.This generator makes the continuous fluid that becomes a mandarin change stream of pulses under the condition that adds auxiliary device, has improved the flow characteristic of boundary layer bottom, the resistance when having reduced FLUID TRANSPORTATION, energy efficient; This stream of pulses can improve the fouling of paraffin in the Crude Oil Transportation; Aspect heat transfer, mass transfer, stream of pulses can improve its thermal efficiency greatly.
In order to realize the foregoing invention purpose, technological scheme of the present invention is:
Pipe pulse stream generator comprises top nozzle body 1, self oscillations cavity 2, following nozzle body 3 and manages 4, top nozzle body 1 is a cylinder, be that 12.5-13.5 °, length are the 5-7 round taper hole and the through hole formed of 0.5-2 times circular hole of the length outlet diameter that is top nozzle body 1 doubly of the outlet diameter of top nozzle body 1 by a cone angle in the top nozzle body 1, the outlet nose end sealing and fixing binding of the inlet nose end of top nozzle body 1 and input pipeline; The inlet nose end sealing and fixing of the outlet nose end of top nozzle body 1 and self oscillations cavity 2 links, self oscillations cavity 2 is a cylinder, change the self-excited oscillation cavity of curvecd surface type in the self oscillations cavity once, the maximum diameter of this self-excited oscillation cavity be self oscillations cavity 2 the inlet opening diameter 2.5-8.8 doubly, the through hole of top nozzle body 1 communicates with the self-excited oscillation cavity, the front end of following nozzle body 3 is a Rotary-table, the cone angle of this Rotary-table is 100-120 °, the rear end of following nozzle body 3 is a cylindrical body, in the following nozzle body 3 manhole is arranged, impact walls on the Rotary-table of following nozzle body 3 is positioned at the rear end of the self-excited oscillation cavity, following nozzle body 3 links with the outlet nose end sealing and fixing of self oscillations cavity 2, the manhole of following nozzle body 3 inlet nose end end face is 2-2.8 times of inlet opening diameter of self oscillations cavity 2 to the distance of the inlet nose end end face of the self-excited oscillation cavity, the through-hole diameter in the following nozzle body 3 and the inlet opening diameter ratio of self oscillations cavity 2 are 1-2, the length of following nozzle body 3 is 1-3 times of the through-hole diameter in the following nozzle body 3, cone angle is the pipe 4 of 25-35 ° through hole in the outlet nose end of nozzle 3 is equipped with down, and the outlet nose end of this pipe 4 and the inlet nose end sealing and fixing of output pipeline link.
The present invention realizes goal of the invention like this: when the impact walls under the pressure flow body arrival that top nozzle body 1 penetrates on the nozzle body 3 also interacts with it, because the instability of shear layer, produce the pressure oscillation ripple in the impact zone, this oscillating wave is upstream propagated with the velocity of sound, bring out new vorticity pulsation again, when the pressure pulsation that makes separation zone and impact zone reverse each other, will form the cyclic process that vorticity disturbance-amplification-pulsation of Xin vorticity produces, constantly repeat this process and in the self-excited oscillation cavity, form strong self oscillations, and eject with the through hole of nozzle body 3 and the through hole of pipe 4 under the mode warp of stream of pulses.
The present invention has following technique effect:
1, this generator is under the condition that adds auxiliary device, the special shape and the specific border condition that rely on top nozzle body 1, self oscillations cavity 2 and following nozzle body 3 self to have, change stream of pulses into after making the self-excited oscillation cavity of flowing through, and the amplitude that will go out flowing pressure is brought up to incoming-flow pressure (115-130) %, improved the flow characteristic of boundary layer bottom, drag losses when having reduced FLUID TRANSPORTATION, energy efficient.
2, stream of pulses can improve the fouling of paraffin in the Crude Oil Transportation.
3, aspect heat transfer, mass transfer, stream of pulses also can improve its thermal efficiency greatly.Experiment shows: its thermal efficiency improves can reach 10%.
