Problems solved by technology

[0005] The purpose of the present invention is: in order to solve the problem that the existing microwave heating device for high-level waste liquid transports high-level waste liquid through pipelines, but because high-level waste liquid usually contains more solid waste, it is easy to have pipelines during the transportation process. The phenomenon of clogging will affect the process efficiency and increase the risk of nuclear radiation. The present invention provides a microwave heating treatment system for high-radioactive nuclear industrial waste, which transports high-level waste liquid in barrels and microwaves the high-level waste liquid. Heating, simplifying processes and piping, thereby increasing efficiency and reducing the risk of radiation exposure to operators

Abstract

The invention discloses a microwave heating treatment system for high-radioactivity nuclear industry waste, and relates to the technical field of treatment of the high-radioactivity nuclear industry waste. The microwave heating treatment system comprises a sealing box and a control system. A microwave heating hole is formed in the top of the sealing box. A lifting device is arranged below the microwave heating hole. A sealing door is arranged on the sealing box. A first conveyor for feeding or taking a barrel containing high-radioactivity waste liquid to or away from the lifting device is arranged in the sealing box. A second conveyor is arranged on the outer portion of the sealing box. The control system comprises a touch screen and a PLC (programmable logic controller) electrically connected with the touch screen. The PLC is connected with the first conveyor, the second conveyor, the microwave heating hole and the lifting device electrically. The microwave heating treatment system has the advantages that automatic delivering, sealing, and microwave heating and evaporating of the barreled high-radioactivity waste liquid are realized, the whole process does not need manual on-siteoperations, and no high-radioactivity waste liquid exists on an equipment maintenance site, so that working efficiency is improved, and the risk that operators are radiated is reduced.

Description

technical field [0001] The invention relates to the technical field of high radioactive nuclear industrial waste treatment, and more specifically relates to a microwave heating treatment system for high radioactive nuclear industrial waste. Background technique [0002] The solidification of radioactive waste is to transform gaseous, liquid or solid waste into a monolithic solidified body whose performance indicators meet the disposal requirements. Its purpose is to form an object suitable for handling, transportation and temporary storage that meets the disposal requirements. For high-level waste liquid, before solidification, it is usually necessary to reduce the amount of liquid in the waste liquid, so as to facilitate later transportation, storage and process development. The existing method of reducing the amount of high-level waste liquid is heating and evaporating. Among them, the method of microwave heating and evaporating has simple process, low cost and good evapor...
