Problems solved by technology

The delivery method of the process solution in a post-treatment plant mainly uses metering pumps, steam jet pumps and air lifters, which have achieved high delivery effects, but there are still limitations in use: during the process of delivering material liquids, metering pumps do not have The maintenance-free function makes maintenance difficult; at the same time, the steam jet pump will also heat and dilute the feed liquid; the air lifter will form radioactive gas due to direct and full contact between the compressed air and the radioactive feed liquid, and the radioactive gas needs to be treated with an efficient gas purification system

Abstract

The invention relates to the technical field of fluid conveying, and particularly discloses a reverse fluid steering conveying device. The reverse fluid steering conveying device comprises a pump body, a drainage pipe, a driving nozzle and a diffusing pipe, wherein the drainage pipe, the driving nozzle and the diffusing pipe are separately connected with the pump body. According to the reverse fluid steering conveying device, through the special arrangement of various pipe diameter size, the fluid conveying flow and efficiency under the conditions of high-lift, long distance or slag inclusioncan be obviously improved, and safe and reliable operation of a high corrosive, high-temperature, toxic, radioactive liquid inclusion or slag inclusion conveying system can be ensured due to the factthat power of the reverse fluid steering conveying device is compressed air and rotatable parts do not exist.

Description

technical field [0001] The invention belongs to the technical field of fluid conveying, and in particular relates to a reverse fluid steering conveying device. Background technique [0002] In the production of hazardous fluid transportation, the transportation of special fluids such as radioactive, highly toxic, highly corrosive, high temperature, and high pressure has always been a difficult technology. Since the human body is not suitable for close contact, maintenance-free conveying equipment is generally used. When the radioactive material liquid in the nuclear reprocessing process is conveyed, it is required to avoid leakage during the process, and the conveying device is completely installed in the equipment room with a shielding layer to implement remote operation. The process solution conveying method of a post-processing plant mainly adopts metering pump, steam jet pump and air lifter, which has achieved high conveying effect, but there are still limitations in use...
