Embodiment 1

[0053] Cyclone purification process for coolant in boron removal section of boron recovery system

[0054] 1. Implementation process

[0055] Such as figure 2 shown.

[0056] 2. Key equipment

[0057] The complete set of separation device combined with micro-cyclone core tube assembly and filter ash hopper is the key equipment in this process. Among them, the core tube assembly of the vertical micro-cyclone is placed in the shell of the separation device, and the filter ash hopper is placed on the top of the micro-cyclone separation device to connect the bottom flow of the micro-cyclone. The processing capacity of the equipment is 10m 3 / h, the external dimension is Φ600×2400. The top is closed with a tube plate type, and the movable ash hopper is used to facilitate the subsequent replacement of the ash hopper.

[0058] 3. Running results

[0059] The density of the dispersed phase used in the experiment is 1.16g / cm 3 , Concentration of 10ppm containing resin partic...

Abstract

The invention relates to coolant rotational-flow purification methods and devices for boron removal sections of boron recycle systems and provides a coolant rotational-flow purification method for a boron removal section of a boron recycle system. The method comprises the following steps that (i) a micro-rotational-flow separation complete device is provided, wherein the device comprises a shell (1), a micro-cyclone core tube (3) and a dust hopper (9); the shell (1) comprises an upper cavity, a middle cavity (6) and a lower cavity; the micro-cyclone core tube (3) is arranged in the middle cavity (6); the dust hopper (9) is arranged in the upper cavity; (ii) in the boron removal section, reactor coolant distillate is fed into the middle cavity of the micro-rotational-flow separation complete device after boron removal is performed, and rotational-flow separation is performed on the distillate through the micro-cyclone core tube to separate solid impurity particles from the distillate to obtain concentrate containing the solid impurity particles and clear liquid; (iii) the obtained concentrate is fed into the upper cavity to be settled in the dust hopper, so that filtrate is obtained; (iv) the obtained filtrate and the obtained clear liquid converge and then flow to downstream equipment.

Description

technical field [0001] The invention belongs to the field of nuclear power environmental protection, and relates to a separation process and device for a filter device with a long service life, low radiation risk when replacing equipment parts, and an integrated micro-swirl core tube assembly and ash hopper. Specifically, the present invention relates to a method of replacing the traditional filter with a complete separation device integrated with a micro-swirl core tube assembly and a filter ash hopper to remove boron recovery system boron removal section coolant broken resin solid particles, and implement the method The device used in the desolidification process. Background technique [0002] At present, the solid-liquid separation mainly adopts gravity sedimentation, filtration separation and cyclone separation technology. Gravity settling is the easiest way to separate solids from liquids. Only when the particles are larger and the flow rate is smaller, the effect of g...
