Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] A saturated steam decontamination device is composed of four parts: a medicine box decontamination reagent part, a water tank part, a heating boiler part, and a water gun part. Deionized water is heated to become saturated steam at 180°C and 10 bar, combined with decontamination reagents, and sprayed from a water gun to produce a decontamination effect.

[0042] The main function of the medicine box part is to hold the decontamination reagent used in the decontamination process, and the decontamination reagent is mixed with saturated steam through the liquid medicine pump to complete the decontamination work. If there is no need to use decontamination reagents, this part can be isolated separately and only use saturated steam for decontamination;

[0043] The main function of the water tank is to hold the deionized water that ...

Abstract

The invention belongs to the technical field of radioactive decontamination, and particularly relates to a saturated steam decontamination device, which comprises a medicine box part, a water tank part, a heating boiler part and a water gun part. Deionized water is heated into saturated steam with the temperature of 180 DEG C and the pressure of 10 bar, the saturated steam is combined with a decontamination reagent and sprayed out through a water gun, and therefore, a decontamination effect is achieved. The medicine box part is mainly used for holding the decontamination reagent used in the decontamination process, and the decontamination reagent and saturated steam are mixed through a liquid medicine pump to jointly complete decontamination work. The water tank part can hold deionized water for providing the saturated steam in the decontamination process, and the deionized water is conveyed to a boiler for heating through a boiler water pump. Compared with a traditional ultrasonic oxidation-reduction decontamination device, the provided saturated steam decontamination device is obvious better in decontamination effect through field tests.

Description

technical field [0001] The invention belongs to the technical field of radioactive decontamination, and in particular relates to a saturated steam decontamination device. Background technique [0002] Radioactive decontamination refers to the activities of removing or reducing unwanted radionuclides from items of radioactive pollutants by appropriate methods. Decontamination can reduce radioactive levels and reduce the exposure dose of operators; reduce shielding and remote operation, and facilitate disassembly activities; make some materials recyclable, and the site can be opened without restrictions; reduce the amount of waste, and reduce waste storage and transportation and disposal burden. [0003] Non-fixed pollution: The pollution nuclide and the surface of the object are combined by intermolecular forces, and the combination of the two is loose and easy to decontaminate. [0004] Weakly fixed pollution: The pollution nuclide is combined with the surface of the objec...
