2) the garbage enters the high-temperature section of the furnace body, the garbage is completely combusted due to the increase of the sprayed oxygen amount of the multi-oxygen combustor, so that the temperature quickly reaches over 1000-1300 ℃, and organic matters and toxic and harmful gases in the garbage are completely cracked in the high-temperature section;
3) the flue gas generated in the high-temperature section moves downwards to enter a flue gas component adjusting section, and the oxygen injection amount of a multi-oxygen burner on the side wall of the furnace body is controlled through a carbon monoxide concentration sensor and an oxygen concentration sensor which are arranged on a pipeline of a flue gas outlet of the incinerator, so that the oxygen content in the flue gas at the outlet of the incinerator is zero, the carbon monoxide content is zero, and more than 99 percent of the oxygen is carbon dioxide;
4) the waste incineration residues are discharged out of the incinerator through a residue discharge assembly;
5) the high-temperature flue gas firstly passes through a high-temperature dust remover to remove larger particles in the smoke dust; the flue gas enters a waste heat recoverer after large particles are removed by a high-temperature dust remover, the waste heat recoverer treats the flue gas by adopting a quenching process, the cooling retention time of the flue gas is shortened, and the secondary generation of dioxin is prevented; hot water heating and collection are carried out on a heat source generated after heat exchange of the preheating recoverer, and meanwhile, low-temperature flue gas after heat exchange enters a bag-type dust collector;
6) after impurities of the low-temperature flue gas are further removed by the bag-type dust collector, the low-temperature flue gas enters the activated carbon adsorption device to purify trace sulfides and nitrides in the flue gas again.
Through multiple tests in the field, the method has the following findings:
the flue gas generated by the incineration of the polyoxin garbage is basically all high-concentration carbon dioxide, and after the carbon dioxide gas is subjected to waste heat recovery, cloth bag dust removal and activated carbon adsorption, a small amount of harmful components such as nitride, sulfide, dioxin and the like are completely removed, the carbon dioxide gas can be used as a gas fertilizer for vegetable greenhouses, and agricultural ecology is benefited. Carbon dioxide is an important raw material for plants to produce carbohydrates through photosynthesis. The concentration of carbon dioxide in the air is about 0.03%. If the concentration of carbon dioxide in the air is increased to 0.1-0.15% by a manual application method, the intensity of photosynthesis can be greatly improved, and the yield of crops is increased. According to statistics: the carbon dioxide is used in the vigorous growth period and the mature period of crops, the effect is obvious, the yield of vegetables can be increased by 90 percent, the yield of rice can be increased by 70 percent, the yield of soybeans can be increased by 60 percent, and the yield of sorghum can be increased by even 200 percent.
