Embodiment 1

[0058] Removing Solid Particle Impurities Using Micro-Swirl Flow Separation Package in Purification Circuit of Reactor Pool

[0059] 1. Implementation process

[0060] Such as figure 2 shown.

[0061] 2. Key equipment

[0062] The key equipment in this technological process is a complete set of micro-swirl separation device coupled with a micro-swirl core tube and a filter ash hopper. Among them, the side-by-side vertical micro-swirl core tube assembly is placed in the micro-swirl separation device, and the filter ash hopper is placed at the bottom of the micro-swirl separation device to connect with the bottom flow of the micro-swirl core tube. 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.

[0063] 3. Control

[0064] Under full load conditions, the circulation flow of the process is 10m...

Abstract

The invention relates to a cyclone purification method and device for cooling water of a purification loop of a reactor pit of a pressurized water reactor nuclear power plant. The method comprises the following steps: (i) providing a complete micro-cyclone separation device which comprises a shell (11), a micro-cyclone core tube (3) and an ash bucket (4), wherein the shell (11) comprises an upper cavity (1), a middle cavity (8) and a lower cavity (6), the micro-cyclone core tube (3) is arranged in the middle cavity (8), and the ash bucket (4) is arranged in the lower cavity (6); (ii) conveying the cooling water into the middle cavity of the micro-cyclone separation complete device, carrying out cyclone separation on the cooling water by using the micro-cyclone core tube so as to remove entrained solid impurities, so as to obtain a concentrated solution and purified water; (iii) sending the obtained concentrated solution into the lower cavity, and settling in the ash bucket to obtain filtrate; and (iv) mixing the obtained filtrate and the obtained purified water to flow to downstream equipment.

Description

technical field [0001] The invention belongs to the field of nuclear power environmental protection, and relates to a micro-swirl separation technology and device with a long continuous operation period and low radioactive solid waste production due to equipment replacement, in particular to an integrated micro-swirl separation technology and a filter ash hopper device The invention discloses a method for removing solid impurities in cooling water of a nuclear power plant reactor pool purification circuit, and a device for implementing the method. Background technique [0002] At present, there are a large number of water purification processes in the petrochemical, coal chemical and nuclear power generation industry production facilities, and the current main solid-liquid separation uses gravity sedimentation, filtration separation and cyclone separation technology. Gravity settling is the most economical way to separate with the help of gravity without external force, but ...
