Abstract

The invention belongs to the technical field of nuclear power plant radioactive waste disposal, and particularly relates to a passive feeding device for a waste liquid drying treatment system. The passive feeding device for the waste liquid drying treatment system is located between a feeding pump and a drying device, and comprises a buffering tank, an isolation valve, a three-way valve, a measurement tank, a pipeline, a liquid level meter, an exhaust pipeline, a raw material tank, an emptying valve and a steel barrel. The bottom of the buffering tank is connected with the first way of the three-way valve, and the isolation valve is arranged on a connecting pipeline. The second way of the three-way valve is connected with the bottom of the measurement tank, and the top of the measurement tank and the top of the buffering tank are connected through the exhaust pipeline. The third way of the three-way valve is connected with the steel barrel, and the steel barrel is located inside the drying device. The bottom of the raw material tank is connected with the feeding pump, the feeding pump is connected with the top of the buffering tank through the pipeline, the top of the raw materialtank is connected with the bottom of the buffering tank, the emptying valve is arranged on the raw material tank, and the liquid level meter is further installed on the top of the buffering tank. Thepassive feeding device for the waste liquid drying treatment system can achieve feeding accurate measurement and solves the problems that the feeding quantity is not easily controlled, and the material liquid possibly overflows.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant radioactive waste treatment, and in particular relates to a passive feeding device used in a waste liquid drying treatment system. Background technique [0002] Using in-barrel drying technology to treat liquid wastes such as radioactive distillation residues and chemical waste liquids is a popular method for nuclear power plants to treat liquid wastes such as radioactive distillation residues and chemical waste liquids. like figure 1 As shown, liquid wastes such as radioactive distillation residue and chemical waste liquid stored in the raw material tank 1 are sent to the steel drum in the drying device 3 through the feeding pump 2 for drying treatment, and the secondary steam generated by drying is condensed Temporarily stored, discharged to the environment after passing the test and analysis. [0003] figure 1 The feeding system consisting of middle raw material tank 1, feeding p...
