Abstract

Technical Field
[0001] The utility model relates to a waste incineration device, in particular to a mobile waste incineration treatment device. Background Art
[0002] The current treatment of combustible low-level radioactive waste primarily relies on incineration, which oxidizes and incinerates the waste into ash. The ash is then solidified and stored or disposed of. The exhaust gas from the incineration process is then properly treated and released into the atmosphere after meeting emission standards. Existing conventional incineration equipment, when applied to low-level radioactive waste treatment, suffers from incomplete combustion in a single combustion chamber, resulting in a low volume reduction rate.

[0020] Furthermore, the elevator is equipped with a robotic arm to grab and feed materials.
[0021] By adopting the above technical solution, the beneficial effects of the utility model are:
[0022] 1. Use an isolation room and an exhaust fan in the ventilation device to ensure negative pressure operation in the container, effectively prevent gas from overflowing from the container and avoid leakage pollution.
[0023] 2. Use a mechanical arm to grab the packed low-level waste and prevent it from being on the lifting trolley. The hoist drives the lifting trolley to the height of the feeding port of the hopper. The door opening hydraulic cylinder is controlled to rotate and drive the feeding door to open. At this time, the flip hydraulic cylinder does not work and the flip plate is closed. The trolley hydraulic cylinder is controlled to push the lifting trolley into the feeding hopper. The pushing hydraulic cylinder is controlled to push the pushing plate to push the low-level waste into the feeding hopper. The lifting trolley is then withdrawn and reset. After the feeding door is closed, the flip hydraulic cylinder is controlled to drive the flip plate to open to allow the low-level waste to fall into the incinerator. The double interlocking setting of the feeding door and the flip plate ensures negative pressure operation in the incinerator and no harmful gas overflows.
[0024] 3. In the first combustion chamber of the incinerator, the first diesel burner is combined with the first blower to blow air and supply oxygen for preheating and ignition; then the second diesel burner in the second combustion chamber is used to further incinerate the high-temperature flue gas from the first combustion chamber to eliminate black smoke and ensure that harmful substances such as flue gas and fly ash will be completely decomposed.
[0025] 4. Considering that low-level radioactive waste may produce nitrogen oxides, the urea storage tank of the SNCR urea metering injection device is used to deliver urea to the second combustion chamber through a pump, meter, and spray gun to remove nitrogen oxides in the flue gas.
[0026] 5. The quenching system, located behind the incinerator, consists of an upper spray chamber and a lower water tank. The spray chamber is equipped with a high-pressure spray gun at the front, a circulating spray gun in the middle, and an emergency spray gun at the rear. The water tank is divided into two compartments by internal partitions: a clean water tank and a wastewater tank. Both the clean water tank and the wastewater tank are equipped with overflow and drain ports, and level sensors monitor the water levels within the tanks. The clean water tank has a tap water inlet and outlet, supplying water to the high-pressure and emergency spray guns, and the water volume is adjusted according to temperature fluctuations. The upper portion of the wastewater tank is connected to the spray chamber via a pipe, receiving the incompletely atomized circulating water from the spray chamber. The bottom of the wastewater tank passes through a filter and a centrifugal pump before connecting to the circulating water spray gun.
[0027] The quenching system pumps water from an external source into a clean water tank. The water is then sprayed into the spray chamber within the quenching shell via quenching spray guns via a pump pipeline. The quenching spray guns atomize the air using compressed air. The appropriate number of spray guns is selected based on the flue gas temperature. The denitrified, high-temperature flue gas enters the spray chamber, where it fully contacts and exchanges heat with a large amount of atomized water, rapidly cooling the flue gas to below 200°C. If the flue gas temperature at the spray chamber outlet exceeds 200°C, the system controls the emergency spray guns to open for auxiliary cooling. During the water spraying process, the quenching spray guns have a certain scrubbing effect on the high-temperature flue gas, achieving the integrated functions of quenching, deacidification, and dust removal.
[0028] After the quenching water has been circulated for a period of time, the ash, inorganic salts and other substances in the water increase and are no longer suitable for use. When the water level in the sewage tank reaches a certain height, the system controls the circulation spray gun to open and spray the circulating water in the sewage tank into the spray chamber to assist in cooling and digesting the wastewater or directly discharge it from the system through the drain valve.
[0029] Alkali is injected into the water tank through the alkali storage tank and the alkali metering pump, so that the clean water in the clean water tank becomes weakly alkaline. The alkali plays an auxiliary deacidification role and can remove part of the HCL and SO2 in the high-temperature flue gas.
[0030] 6. The quenching system connects the activated carbon / sodium bicarbonate injection device to the flue gas pipe that sends flue gas to the bag filter. The activated carbon and sodium bicarbonate powders are fed into the flue gas pipe through a rotary feeder and a powder quantitative feed pipe. The compressed air is sprayed at high speed and enters the flue to be fully mixed with the flue gas.
[0031] Directed activated carbon and sodium bicarbonate powder are sprayed between the quenching system and the bag filter as adsorbents. The activated carbon mixes intensely with the flue gas, utilizing its large specific surface area and strong adsorption capacity to purify residual dioxins, heavy metals, and other pollutants in the flue gas. After injection, the activated carbon mixes with the flue gas in the flue for initial adsorption. The evenly mixed flue gas then enters the bag filter, where the activated carbon particles are adsorbed onto the filter bag surface, where they continue to adsorb, thereby improving the removal efficiency of dioxins.
[0032] At the same time, the injected sodium bicarbonate reacts with the residual acid gas in the flue gas to perform dry deacidification, further removing the residual acid gas in the flue gas and preventing alkaline substances from being adsorbed on the subsequent bag dust collector and causing the filter bag to absorb moisture.
[0033] 7. The ash falling from the chain grate of the incinerator is sent out of the ash screw conveyor through the furnace screw conveyor and the gate valve, and then is weighed and collected in the ash collection bucket; the dust in the ash collecting bin of the dust collector is sent to the fly ash screw conveyor through the gate valve, and then sent out of the ash screw conveyor by the fly ash screw conveyor, completing the integrated ash collection.
[0034] 8. The bag filter sends the flue gas into the condenser, and the chiller sends cooling water to the cooling coil in the condenser to cool the flue gas to below 60℃. The water vapor in the flue gas is condensed and precipitated at low temperature, and then the water mist is eliminated by the demister in the horizontal steam-water separator. The condensed water is effectively and efficiently collected by the baffle in the vertical steam-water separator, and the condensed water is sent to the water tank for recycling. The flue gas after water removal is sent to the flue gas electric heater through a backup induced draft fan, and the flue gas is heated to above 110℃88 and discharged through the chimney to eliminate the white mist in the flue gas and ensure that the emission meets the standards.
