Pulverization matching-type multi-inlet medium ejector

Abstract

The invention relates to a pulverization matching-type multi-inlet medium ejector which comprises a pipe body, a nozzle and at least two pulverization branch pipes, wherein the nozzle and the pulverization branch pipes are respectively and hermetically communicated with the pipe body; the pipe body is provided with a vacuum chamber as well as a nozzle hole and a venturi which are respectively and hermetically communicated with the vacuum chamber; the nozzle is arranged in the nozzle hole, and an atomizing nozzle is aslant communicated with the side periphery of the vacuum chamber; the free ends, which are located outside and inside the vacuum chamber, of the atomizing nozzle are respectively an outer port and an inner port; the interior axes of the pulverization branch pipes are provided with pulverization sticks; the free ends, which are located at the inner port, of the pulverization stick are provided with pulverization heads. The pulverization branch pipes are transformed into a pulverization device provided with the pulverization sticks, so that the flow velocity and pulverization degree of different steam or fluids which flow through the two pulverization branch pipes are adjusted by virtue of adjusting the positions of the pulverization heads in the inner port, and the different adjusting schemes of the pulverization sticks in the two pulverization branch pipes can be used for ensuring the matching of the fluids which enter into the ejector.

Description

technical field [0001] The invention relates to a medium injector, in particular to an atomization ratio multi-inlet medium injector. Background technique [0002] The medium ejector is a mechanical device with three effective functions of vacuuming, condensation and drainage. It uses a certain pressure of the fluid medium to flow through symmetrical nozzles with a certain inclination to spray out and gather at a focal point. Due to the high flow rate of the jet fluid medium, a negative pressure is formed around the chamber to create a vacuum in the chamber. In addition, due to the direct contact between the secondary steam and the jet fluid medium for heat exchange, most of the steam condenses into water, and a small amount of uncondensed The steam and non-condensable gas are also rubbed against the high-speed jet fluid medium, mixed and extruded, and are discharged through the diffuser tube, so that a higher vacuum is formed in the chamber. Medium injectors are widely us...

Problems solved by technology

However, at present, there is only one atomizing branch pipe in the production of medium injectors, and the flow rate of the atomizing branch pipe is not perforated, so the use is relatively passive
