Distributed circular seam ejector device

Abstract

The invention discloses a distributed circular seam ejector device. The device adopts a pipeline connection mode and sequentially comprises a low-energy fluid inlet section, a high-energy fluid inletsection and a mixed fluid outlet section which are connected in sequence, and a binary circular seam ejector is arranged in a pipeline near the high-energy fluid inlet section; through holes are formed in the surface of the high-energy fluid inlet section and communicate with an external high-pressure tank; the low-energy fluid inlet section, the high-energy fluid inlet section and the mixed fluidoutlet section share the same central axis; the binary circular seam ejector comprises annular spray pipe unit bodies which are arranged in an annular mode, the spray pipe unit bodies are connected through reinforcing ribs, part of the reinforcing ribs are of a hollow structure, and high-energy fluid enters the spray pipe unit bodies from the through holes in the high-energy fluid inlet section and is sprayed out from outlets of the spray pipe unit bodies; and annular spray pipes are arranged in the spray pipe unit bodies. The device is suitable for fluid ejection control of gas and liquid. According to the device, the ejection efficiency is improved, the boundary 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 annular slot 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 is fast or slow. People often hope to inject the low-energy fluid through the high-energy fluid to increase the speed of the low-energy fluid and increase the flow rate of the 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 a certain flow speed and flow can meet the requirements. But in scientific research, people often need to efficiently eject low-energy fluids through high-energy fluids. In power plants, fuel combustion equi...

AI Technical Summary

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
