[0018] Furthermore, it also includes an electric control operation container, which is connected to a main electric control cabinet in the container via wired and / or wireless communication.

[0019] Furthermore, the elevator is equipped with a mechanical arm to grab the feed.

[0020] By adopting the above technical solution, the beneficial effects of the present invention are: 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.

[0021] 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. Then the pushing hydraulic cylinder is controlled to push the pushing plate to push the low-level waste into the feeding hopper. Then the lifting trolley is withdrawn and reset.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.

[0022] 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 burn 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.

[0023] 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, a meter, and a spray gun to remove nitrogen oxides in the flue gas.

[0024] 5. The quenching system is located behind the incinerator and consists of an upper spray chamber and a lower water tank. A high-pressure spray gun is set at the front end of the spray chamber, a circulating spray gun is set in the middle, and an emergency spray gun is set at the rear. The water tank is divided into two chambers, a clean water tank and a sewage tank, by an internal partition. Overflow ports and discharge ports are set for both the clean water tank and the sewage tank, and the water level in the tank is monitored by a liquid level sensor. The clean water tank is equipped with a tap water inlet and outlet to supply water to the high-pressure spray gun and the emergency spray gun, and the water volume is adjusted according to the change in temperature. The upper part of the sewage tank is connected to the spray chamber through a pipe to receive the circulating water that is not completely atomized in the spray chamber. The bottom of the sewage tank is connected to the circulating water spray gun through a filter and a centrifugal pump.

[0025] The quenching system pumps external water into the clean water tank, and then sprays clean water into the spray chamber in the quenching shell through the quenching spray gun through the pump pipeline. The quenching spray gun is atomized by compressed air, and the reasonable number of spray guns is selected according to the flue gas temperature. The high-temperature flue gas after denitrification enters the spray chamber, fully contacts and exchanges heat with a large amount of atomized water, and the flue gas temperature is rapidly cooled to below 200°C. If the flue gas temperature at the spray chamber outlet is higher than 200°C, the system controls the emergency spray gun to open and assist in cooling. During the water spraying process, the quenching spray gun has a certain washing function on the high-temperature flue gas, which can realize the comprehensive functions of quenching, deacidification and dust removal.

[0026] 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.

[0027] In the water tank, alkali liquid is injected through the alkali liquid storage tank and the alkali liquid metering pump to make the clean water in the clean water tank weakly alkaline. The alkali liquid plays an auxiliary role in deacidification and can remove part of HCL and SO2 in the high-temperature flue gas.

[0028] 6. The quenching system connects the activated carbon / sodium bicarbonate injection device to the flue gas duct that delivers flue gas to the bag filter. The activated carbon and sodium bicarbonate powders are fed into the flue gas duct through a rotary feeder and a powder quantitative feed pipe. The compressed air is sprayed at high speed into the flue and fully mixed with the flue gas.

[0029] Directed activated carbon and sodium bicarbonate powder are sprayed between the quenching system and the bag filter as adsorbents. The activated carbon is strongly mixed with the flue gas. The activated carbon has a large specific surface area and strong adsorption capacity to purify the residual dioxins and heavy metals in the flue gas. After the activated carbon is sprayed, it mixes with the flue gas in the flue for preliminary adsorption. Then the evenly mixed flue gas enters the bag filter. The activated carbon particles are adsorbed to the surface of the filter bag and continue to adsorb on the surface of the filter bag, thereby improving the removal efficiency of dioxins.

[0030] 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 the alkaline substances from being adsorbed on the subsequent bag filter and causing the filter bag to absorb moisture.

[0031] 7. The ash dropped 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 is sent out of the ash screw conveyor by the fly ash screw conveyor, completing the integrated ash collection.

[0032] 8. The bag filter sends 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°C. The water vapor in the flue gas is condensed and precipitated at low temperature, and then the mist is eliminated by the demister in the horizontal steam-water separator, and 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°C88 and discharged through the chimney to eliminate the white mist in the flue gas and ensure that the emission meets the standards.
