Abstract

A multi-pipe composite jet pump is a jet device for mixed fluid. The pump comprises a main fluid inlet pipe (11), a composite annular injector (100a) and a general injector (100b) which are concentrically and sequentially connected in series. The composite annular injector (100a) is provided with multiple periphery nozzles (4) uniformly arranged in a ring, circular small mixing pipes (32) with the number the same as that of the nozzles, a periphery mixing chamber (5) and a big annular mixing pipe (33). The inlet end of each periphery nozzle (4) is connected with the main fluid inlet pipe (11), and the outlet end of each periphery nozzle (4) is extended into the periphery mixing chamber (5). A subsidiary fluid inlet (3120) is arranged on the side of the periphery mixing chamber (5). The inlet end of each circular small mixing pipe (32) is connected with the periphery mixing chamber (5), and the outlet end of each circular small mixing pipe (32) is directly connected with the big annual mixing pipe (33). Each periphery nozzle (4) is aligned to and keeps injector spacing with the corresponding circular small mixing pipe (32). The general injector (100b) is provided with a main nozzle (25), a general mixing chamber (61), and a general mixing output pipe (60a). Wherein the main nozzle (25) is located in the centre of the composite annular injector (100a), the inlet end of the main nozzle (25) is connected with the main fluid inlet pipe (11), and the outlet end of the main nozzle (25) extended into the centre of the general mixing chamber (61); the main nozzle (25) is aligned to and keeps injector spacing with the outlet end of the general mixing chamber (61); the inlet end and the outlet end of the general mixing chamber (61) are respectively connected with the big annual mixing pipe (33) and the general mixing output pipe (60a).

Description

technical field [0001] The invention relates to a jet device which injects secondary fluid with low pressure or no pressure by primary fluid with high pressure and outputs medium-pressure mixed fluid. Background technique [0002] The most typical structure among the existing ejectors is a Venturi ejector. The body of the Venturi ejector is a stepped oblong tube with a reaming cavity mixing chamber at the front end, a secondary fluid inlet is set on the side of the mixing chamber, and a nozzle connected to the main fluid inlet pipe is arranged in the mixing chamber, and the nozzle outlet is facing the mixing chamber Converging cone outlet and small diameter mixing output pipe communicated with the mixing chamber constricting cone outlet. [0003] The Venturi ejector passes through the nozzle, so that the working fluid entrains the injected secondary fluid into the mixing chamber and enters the mixing output pipe. The two are mixed in the mixing tube for heat transfer, mass...
