Abstract

The invention discloses a combined steam injection device, and belongs to the technical field of ejector. The combined steam injection device comprises a plurality of ejectors which are independentlyarranged and a connecting part, wherein the plurality of the ejectors are connected with the connecting part in a sealing manner, and the plurality of the ejectors are provided with throttling mechanisms to individually control the flow of a working fluid in each ejector; the ejectors communicate with external steam pipelines through the connecting part. According to the combined steam injection device, throttling mechanisms are arranged on the ejectors to individually control the flow of the working fluid in each ejector. When external gas parameters change, especially when the discharge gasflow changes greatly, the flow of the working fluid in each ejector can be adjusted to enable that the combined steam injection device can achieve the best injection condition and the injection performance required by the combined steam injection device can be met.

Description

technical field [0001] The invention relates to the technical field of ejectors, in particular to a combined steam ejector. Background technique [0002] The working principle of the steam ejector is: the high-pressure steam converts the pressure energy into kinetic energy through the nozzle, and forms a high-speed jet at the outlet of the nozzle, and the pumped fluid is drawn into the suction chamber due to the strong shearing effect between it and the working fluid. The turbulent diffusion effect of the jet boundary layer makes the exchange of mass, momentum and energy between the two fluids, so the velocity of the working fluid decreases continuously, while the velocity of the ejected fluid increases continuously, and a single uniform flow is formed somewhere in the mixing chamber. mixed fluid. The kinetic energy in the diffuser is converted into pressure energy, and the mixed fluid is decelerated and pressurized to a certain back pressure and then discharged out of the ...
