Vehicle-mounted low-level radioactive combustible waste incineration device and process

Abstract

The invention relates to a vehicle-mounted low-level radioactive combustible waste incineration device and a process thereof. The vehicle-mounted low-level radioactive combustible waste incineration device comprises an incineration system, an air supply and exhaust system connected to the incineration system, a flue gas cooling and purification system, a compressed air system and a cooling water circulation system, wherein the incineration system consists of a pyrolysis furnace, a combustion furnace and a fuel tank; the upper part of a hearth of the pyrolysis furnace communicates with the upper part of the combustion furnace; and the fuel tank is connected to a combustor of the pyrolysis furnace and a combustor of the combustion furnace and provides fuel for the combustors. According to the vehicle-mounted low-level radioactive combustible waste incineration device, the incineration and volume reduction treatment of combustible low-level radioactive waste can be achieved; the waste becomes stable incineration ash after combustion; combustion exhaust gas is cooled and purified; and the exhaust gas can be emitted at low temperature after purification so as to meet national emission standards. The vehicle-mounted low-level radioactive combustible waste incineration device has the characteristics of compact and movable equipment, small occupied area, short construction period, simple and convenient operation and maintenance, and the like. The vehicle-mounted low-level radioactive combustible waste incineration device can be moved in a vehicle-mounted manner so as to meet transportation standards. The vehicle-mounted low-level radioactive combustible waste incineration device can adopt an intermittent operation mode, and is simple and convenient to operate and flexible in management mode.

Description

technical field [0001] The invention relates to the field of processing various radioactive combustible wastes produced by nuclear military industry, nuclear power plants, scientific research institutes and other departments, in particular to a vehicle-mounted low-level combustible waste incineration device and a process. Background technique [0002] In the process of nuclear energy development and utilization, nuclear military industry departments and related scientific research institutes will produce radioactive waste, among which combustible waste accounts for the highest proportion, generally 50wt%-90wt%. And management problems are becoming more and more prominent, so it is necessary to find a suitable treatment method as soon as possible. [0003] Incineration is one of the most mature radioactive waste volume reduction treatment methods at home and abroad. It has good volume reduction effect (volume reduction ratio can reach more than 50), stable treatment effect (i...

AI Technical Summary

Problems solved by technology

However, for some units or departments with low total waste generation and scattered locations, conventional incineration facilities have relatively high construction and operation costs, many operating personnel, and complicated management procedures, which are not very suitable for these places in terms of economy and management.

If these wastes are transported to waste treatment facilities, the transportation of radioactive wastes needs to be considered. After the wastes need to be prepared and packaged to meet the corresponding transportation standards, the actual economic and management costs are relatively high.
