Embodiment 1

[0033] This embodiment provides a radioactive waste liquid filter treatment device, including a hoisting unit, a drying unit and a packaging unit,

[0034] The hoisting unit includes a shielding container 6, a gripper and a sling 11. The shielding container 6 is a cylindrical structure with an open bottom and a closed top. The shielding container 6 can adopt a circular cylinder structure or a square cylinder structure, which can be selected according to the external shape of the filter 3, as long as the filter 3 can be accommodated inside the shielding container 6, the outer wall of the filter 3 is preferably the same as the shielding container 6. There is a certain gap between the inner walls of the filter 3 to prevent the outer wall of the filter 3 from contacting the inner wall of the shielding container 6 during the hoisting process, increasing the resistance, or affecting the positioning of the filter 3. Here, the shielding container 6 with a cylindrical structure is selec...

Embodiment 2

[0038]Further improvement on the basis of Embodiment 1, a bottom plate 6a is provided at the opening of the bottom end of the shielding container 6, and the drawer structure of the bottom plate 6a is arranged on the bottom end of the shielding container 6, and the drawing direction of the bottom plate 6a is in line with the shielding container 6 The axial direction of the shielding container 6 is vertical, that is, the base plate 6a enters and exits the shielding container 6 along the radial direction of the shielding container 6; , the bottom plate 6a is used to provide support for the filter 3 located in the shielding container 6 . Specifically, the structure of the bottom plate 6a is adapted to the radial cross-sectional shape of the shielding container 6, and a notch is provided on the side wall near the bottom of the shielding container 6, and the inner wall near the bottom of the shielding container 6 extends circumferentially. A guide groove is provided, and after the b...

Embodiment 3

[0044] This embodiment provides a radioactive waste liquid filter treatment process, specifically using the device provided in Embodiment 2 to operate, such as figure 1 As shown, the processing steps are as follows:

[0045] Step 1, the filter 3 containing impurities in radioactive waste liquid is installed on the filter holder 4 in the waste liquid storage tank 5, the top of the storage tank 5 is set in a hole directly above the filter 3, and the hole plug 2 is passed through the hole Sealing; when using the device provided by the present invention to handle the operation, at first, install the sling 11 and the grabber on the crane 1a, run the crane 1a to the directly above the hole, make the grabber align with the connector on the hole plug 2, and the lower sling 11 and control the gripper to grab the connecting piece, lift the hole plug 2 and transport it to another open location for storage, such as figure 2 shown.

[0046] Step 2, run the crane 1a, grab the quick conne...

Abstract

The invention discloses a treatment device for a radioactive waste liquid filter, which comprises a hoisting unit, a drying unit and a packaging unit. The hoisting unit includes a shielding container, a grab and a sling; The output end of the fan is connected with the input end of the hot air pipe, the output end of the hot air pipe is used to communicate with the perforation on the shielding container, and the through hole on the top of the shielding container is used for exhausting; the packaging unit includes a packaging barrel, which is used for Store dried filters. The filter treatment process mainly includes five steps: hole plug removal and lifting, shielding container installation and filter retrieval, filter drying, shielding container transportation, and filter barreling. The invention provides a treatment device and treatment process for a radioactive waste liquid filter. The filter containing more radioactive impurities and moisture and a higher radiation level is retrieved and post-treated, and finally put into a packaging barrel. The whole process of operation It is beneficial to protect the safety of personnel and the environment and improve operating efficiency.

Description

technical field [0001] The invention relates to the field of radioactive waste liquid treatment, in particular to a radioactive waste liquid filter treatment device and process. Background technique [0002] Due to the large amount of radioactive waste liquid generated during the operation, maintenance, overhaul and decommissioning of nuclear facilities, these waste liquids are stored in special radioactive waste liquid storage tanks (hereinafter referred to as storage tanks). During long-term storage, the effluents of these storage tanks produce large quantities of insoluble solid particles suspended in the effluent and deposited on the bottom of the storage tanks. At present, these impurity-containing waste liquids are treated through the radioactive waste liquid slag removal system, and most of the radioactive impurities in the waste liquid are filtered out through filters. The filter is installed on the top filter mounting bracket in the storage tank, and there are hole...
