Problems solved by technology

Among the existing conveying equipment, conventional mechanical pumps obviously do not meet the above requirements
Although the steam jet pump can meet the above requirements, the use of steam as the transport medium increases the amount of waste liquid transported, seriously reduces the transport efficiency and increases the amount of subsequent treatment of waste liquid

Embodiment 1

[0031] Such as Figure 1-2 As shown, it is a schematic structural view of the air injector group 11 used for passive fluid delivery in the present invention, the air injector group 11 includes an I-shaped connecting pipe 111, and the I-shaped connecting pipe 111 includes a first arm pipe 1111, the second arm tube 1112 and the connecting arm tube 1113 connecting the first arm tube 1111 and the second arm tube 1112;

[0032] The upper side of the first arm pipe 1111 is fixed with a pressure punching nozzle 112, and the lower side is fixed with a first Laval nozzle 113, and the nozzle 1121 of the pressure punching nozzle is located at the shrinkage of the first Laval nozzle. In the pipe 1131 and facing the throat 1132 of the first Laval nozzle, and the gap between the nozzle 1121 of the pressure flushing nozzle and the shrinkage pipe 1131 of the first Laval nozzle forms the first mixing Chamber 116; the upper side of the second arm pipe 1112 is fixed with a vacuum nozzle 114, an...

Embodiment 2

[0048] Different from the above-mentioned embodiments, the air injector set 11 for passive fluid delivery in the present invention includes a vacuum injector 17 and a press-ram injector 16 . The stamp injector 16 includes a stamp housing, a stamp nozzle 112 , a first Laval nozzle 113 and a first mixing chamber 116 . The vacuum ejector 17 comprises a vacuum housing, a vacuum nozzle 114 , a second Laval nozzle 115 and a second mixing chamber 117 . The stamping shell is a T-shaped connecting pipe formed by connecting the first arm tube 1111 and the third arm tube 1113, the vacuum shell is the second arm tube 1112, and the third arm tube 1113 The free end of the third arm tube 1113 is provided with a connecting structure that is connected to the side opening of the second arm tube 1112, such as a threaded connection structure, or the free end of the third arm tube 1113 is directly connected to the side opening of the second arm tube 1112 Phase welding. Or the punching shell is a...

Abstract

The invention provides an air ejector set for passive fluid conveying. An I-shaped connecting pipe is adopted to connect a pressure impact ejector and a vacuum ejector, conveying of passive fluid is achieved through cooperative work of the pressure impact ejector and the vacuum ejector, the structure is simple, the long-distance operation requirement can be met, maintenance is not needed, and rapid replacement can be achieved.

Description

technical field [0001] The invention relates to the field of fluid transportation, especially the field of radioactive fluid transportation, and in particular to an air injector group for passive fluid transportation. Background technique [0002] A passive safety system refers to a system that does not rely on external triggers and power sources, but relies on natural properties such as natural convection, gravity, and pressure accumulation to achieve safety functions. [0003] At present, for the treatment of radioactive fluids or other highly toxic fluids, such as the transportation of radioactive liquids in nuclear reprocessing plants, since the objects to be transported are medium and high radioactive solutions or other highly toxic fluids, the entire processing equipment must be placed in a biological shielding In the equipment room, the conveying equipment is required to have no moving parts, simple structure, reliable operation, convenient operation and minimal maint...
