Referring to fig. 1, the present embodiment provides an atmosphere sealing method for a radioactive contamination glove box disassembly process, comprising the following steps: injecting a sealing blocking agent capable of being cured and molded into a position 9 to be disassembled; step two, cutting off the position to be disassembled 9 after the sealing and blocking agent is cured and molded; and step three, sealing two sections formed after the position 9 to be disassembled is cut off. The atmosphere sealing method utilizes a sealing blocking agent to seal the interior of the position 9 to be disintegrated before disintegration, and seals two cross sections formed after the position 9 to be disintegrated is cut after disintegration. So, effectively avoided disintegrating the inside high concentration radioactive aerosol of in-process glove box and revealed, harm operating personnel is healthy and takes place to the condition that causes radioactive contamination to the workplace.
In this embodiment, in step one, the sealing and blocking agent is injected into the position to be disassembled 9 by using an injection tool. With the injection tool, no gas is introduced into the interior of the glove box. Glove box internal pressure is less than external atmospheric pressure, for the negative pressure, if gaseous to the inside introduction of glove box, leads to the interior malleation in the twinkling of an eye of glove box easily, and the malleation can make the inside aerosol of glove box leak more easily.
Further, the injection tool is a manual lance. It should be noted that the injection tool is not limited to a manual spray gun, and other tools capable of injecting the sealing and blocking agent into the position to be disassembled 9 without introducing gas may be used, and the specific structure of the manual spray gun belongs to the prior art, and will not be described herein again.
In the specific use process, the injection tool is placed into the glove box through the auxiliary box 3 of the glove box, an operator operates the injection tool by using a glove 8 on the glove box from the outside, and the sealing and blocking agent is injected into the position 9 to be disintegrated.
Two door openings are provided inside and outside the sub-tank 3 of the glove box, the outside door opening is used for isolating the inside of the sub-tank 3 from the outside atmosphere, and the inside door opening is used for isolating the inside of the glove box from the inside of the sub-tank 3. When the injection tool is placed inside the glove box, the door on the outside of the sub-box 3 is first opened, the injection tool is placed inside the sub-box 3, and then the door on the inside is opened, and the operator manipulates the gloves 8 of the glove box to move the injection tool to the inside of the sub-box 3. Through setting up inside and outside twice and opening the door, effectively avoided taking place the condition that the inside radioactive aerosol of glove box leaks when placing injection instrument or other equipment in the glove box inside.
