Embodiment Construction

[0039] The invention discloses a decontamination device, which improves the decontamination efficiency by using the output of radioactive waste and the collective dose of personnel during the decontamination process of a refueling pool.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] Such as figure 1 , figure 2 and image 3 As shown, the embodiment of the present invention provides a decontamination device, including a container 11 , a nozzle 172 , a liquid pipeline 14 , an air pipeline 13 , a d...

Abstract

The invention discloses decontamination equipment. The decontamination equipment comprises a container (11), a liquid pipe (14), an air pipe (13), a decontamination main, a first foam generator (171) and a nozzle (172), wherein the container (11) is used for containing decontamination liquid, one end of the liquid pipe (14) extends into the portion below the liquid level, and the portion below the liquid level is the portion below the liquid level after the container (11) contains the decontamination liquid; one end of the air pipe (13) is located on the portion above the liquid level of the container (11), and the portion above the liquid level is the portion above the liquid level after the container (11) contains the decontamination liquid; the other end of the liquid pipe (14) and the other end of the air pipe (13) are communicated with one end of the decontamination main; the first foam generator (171) is arranged on the decontamination main; the nozzle (172) is communicated with the other end of the decontamination main. The decontamination equipment effectively makes air and the decontamination liquid mixed to form foam, effectively reduces the use amount of the decontamination liquid, reduces the yield of radioactive waste and personnel collective dose in the decontamination process of a material changing pool, and improves the decontamination efficiency.

Description

technical field [0001] The invention relates to the technical field of decontamination equipment, in particular to a decontamination equipment. Background technique [0002] At present, the decontamination method of the refueling pool of the PWR nuclear power plant mainly adopts the decontamination method of high-pressure jet flow. This method requires many operators, long construction period, incomplete decontamination and large amount of radioactive waste generated, high collective dose of personnel, and low decontamination efficiency. [0003] Therefore, how to reduce the output of radioactive waste and the collective dose of personnel during the decontamination process of the refueling pool and improve the decontamination efficiency is a problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In view of this, the present invention provides a decontamination equipment to reduce the output of radioactive waste and the collective dos...
