Description

Technical field [0001] The invention relates to a refined water treatment device, in particular to a nuclear power secondary circuit condensate polishing system for automatic and efficient transportation of trees [0002] The grease device is installed in the supporting regeneration system of the nuclear power condensate polishing system with a working pressure of 0~1.0MPa. Background technique [0003] At present, it is used in the regenerating system of the secondary circuit condensate polishing system of nuclear power. The existing resin transportation method is a single pump with pipes of different pipe diameters and automatic valves to introduce the water flow into each resin delivery port. The advantage is that it can pass through different pipes. The pipeline properly controls the hydraulic transportation flow. The disadvantage is that the pipeline introduction equipment is messy, can not be controlled centrally and the transportation flow is not easy to accurately control. ...

Problems solved by technology

[0003] At present, it is used in the supporting regeneration system of the nuclear power secondary circuit condensate polishing system. The existing resin delivery method is a single water pump with pipes of different diameters and automatic valves to introduce water into each resin delivery port. The advantage is that it can pass through different pipe fittings. The pipeline properly controls the flow of hydraulic transportation, but the disadvantage is that the equipment introduced into the pipeline is messy, it cannot be controlled centrally, and the transportation flow is not easy to control accurately

[0004] With the vigorous development of my country's nuclear power industry, nuclear power secondary circuit condensate equipment and devices are also being updated at a high speed. Most nuclear power condensate projects adopt the equipment model of pre-anode bed + mixed bed, and the total amount of resin delivery increases. It is more complicated, and the existing water pump and pipeline transportation cannot meet the high requirements of centralized control and simplicity of condensate in the secondary circuit of nuclear power plants
