Problems solved by technology

The annular seam ejector is a relatively classic ejector, but the traditional annular seam ejector has the following disadvantages: first, the energy and material exchange area between the high-energy fluid and the low-energy fluid is not large, and the ejection efficiency is low; second, the high-energy fluid The mixing speed with low-energy fluid is slow, the required mixing section is long, and the uniformity of the mixed fluid is poor; the third is that the ejector has a large size, expensive manufacturing and processing costs, and complex space installation requirements

Embodiment 1

[0037] The number of nozzle units in this embodiment is 8, and each nozzle unit is provided with a binary and a half nozzle, with 4 nozzle units in the upper half and 4 other nozzle units symmetrically distributed in the lower half , the four nozzle units in the upper half are connected and supported by a hollow reinforcing rib that penetrates up and down on the symmetry line, and the four nozzle units in the lower half are respectively connected and supported by the symmetry line Another symmetrical hollow-shaped reinforcing rib connected and supported up and down; the binary nozzle injector 3 is also provided with an annular channel communicating with each nozzle unit, and the high-energy fluid flows from the high-energy fluid inlet section 2 After the through hole enters the annular channel, it is sprayed out from the outlet of the nozzle unit body.

[0038]Numerical simulation results show that, compared with the traditional annular seam ejection, the distributed binary no...

Abstract

The invention discloses a distributed two-dimensional spray pipe ejector device. The distributed two-dimensional spray pipe ejector device uses a pipeline connection mode, and sequentially comprises alow-energy fluid inlet section, a high-energy fluid inlet section and a mixed fluid outlet section which are connected in sequence, wherein an two-dimensional spray pipe ejector is arranged in a pipeline near the high-energy fluid inlet section; a through hole is formed in the surface of the high-energy fluid inlet section and communicates with an external high-pressure tank; the low-energy fluidinlet section, the high-energy fluid inlet section and the mixed fluid outlet section share the same central axis; the two-dimensional spray pipe ejector comprises linear spray pipe unit bodies arranged in parallel; the spray pipe unit bodies are connected through reinforcing ribs; part of the reinforcing ribs are of hollow structures; high-energy fluid enters the spray pipe unit bodies from thethrough hole of the high-energy fluid inlet section and is sprayed out from outlets of the spray pipe unit bodies; and spray pipes are arranged in the spray pipe unit bodies. The distributed two-dimensional spray pipe ejector device is suitable for fluid ejection control of gas and liquid, and has the advantages that the ejection efficiency is improved; the appearance dimension of the ejector device is reduced; and the space installation requirement of the ejector device is lowered.

Description

technical field [0001] The invention belongs to the technical field of flow control, and in particular relates to a distributed binary nozzle ejector device. Background technique [0002] Fluid is a general term for gas and liquid. Most fluids, such as oil, water and air, are indispensable substances for people's life, production and scientific research. The flow speed of the fluid varies from fast to slow, and people often hope to inject low-energy fluid through high-energy fluid to increase the velocity of low-energy fluid and increase the flow rate of low-energy fluid. [0003] In general life and production activities, people do not have high requirements for the flow speed of fluids, such as tap water, gas stations, gas stations, heating and natural gas, etc., only need a certain flow speed and flow rate to meet the requirements. However, in scientific research, people often need to efficiently eject low-energy fluids through high-energy fluids. In power plants, fuel ...
