When the household garbage incineration equipment is used, firstly, garbage is put into the garbage combustion chamber 10 from the garbage putting-in opening 12, a large amount of flue gas is generated in the incineration process of the garbage, the flue gas rises to the top end of the garbage combustion chamber 10 and enters the bottom end of the spray tower 20 through the first pipeline 11, at the moment, the flue gas can continuously rise from the bottom end to the top end of the spray tower 20 inside the spray tower 20, absorption liquid sprayed from the top end is contacted with the flue gas in the falling process, so that large-particle dust, oxysulfide, nitric oxide and the like in the flue gas are absorbed by the absorption liquid and then fall to the bottom end of the spray tower 20, the flue gas treated by the spray tower 20 enters the oil throwing box 22 through the flue gas pipeline, oil and water in the flue gas are separated, the flue gas subjected to oil-water separation enters the low-temperature plasma machine 23 through the flue gas pipeline on the right side of the oil throwing box 22, and harmful gases, harmful gases mainly comprise gases such as hydrogen sulfide, ammonia, benzene, toluene, xylene, formaldehyde, acetone, urethane, resin and the like, when the smoke enters the high-voltage electrostatic chamber 24, the harmful gases are decomposed under the action of a high-voltage electric field, so that the degradation and oxidation effects on the harmful gases such as formaldehyde, xylene, sulfur dioxide, ammonia nitrogen oxides and the like and peculiar smell are generated, the organic substances and the peculiar smell are degraded, the smoke enters the UV photo-oxidation active carbon all-in-one machine 25 along with a smoke pipeline, the polluted gases are decomposed into nontoxic, harmless and tasteless gases through destruction, decomposition and catalytic oxidation, the active carbon has excellent adsorption performance, organic waste gases are effectively adsorbed, the treated smoke enters the heating purifier 26 along with the smoke pipeline for further purification, and finally, the gases which are harmless to the human body and have no pollution to the environment are discharged through the smoke discharge chimney 30, the gas meets the pollution control standard of domestic waste incineration (GB 18485-2014).

The working principle of the low-temperature plasma machine 23 is as follows: when low-temperature plasma is adopted to decompose polluted media such as oil mist, waste gas and the like, the polluted media generate active free radicals under the action of the plasma, and activated polluted molecules are separated after the plasma directional chain chemical reaction. When the average energy of the ions exceeds the bonding energy of the chemical chain in the polluted medium, the molecular chain is cracked, and the polluted medium is decomposed. In view of air purification efficiency, the harmful gas can be eliminated by adopting the principle of combining pulsed corona discharge low-temperature plasma with adsorption technology, wherein the low-temperature plasma is mainly used for removing gases such as hydrogen sulfide, ammonia, benzene, toluene, xylene, formaldehyde, acetone, urethane, resin and the like, and the adsorption material is mainly used for removing byproducts such as carbon dioxide, ozone and the like.

When the flue gas enters the high-voltage electrostatic chamber 24, under the action of pulse corona of working voltage, molecular bonds among various organic gas molecules can be directly broken, so that harmful gases are decomposed, and therefore, degradation and oxidation effects are generated on harmful gases and peculiar smells such as formaldehyde, dimethylbenzene, sulfur dioxide, ammonia nitrogen oxides and the like, and degradation treatment is performed on organic substances and peculiar smells.

When the flue gas enters the UV light oxygen active carbon all-in-one machine 25, the polluted gas is decomposed into non-toxic, harmless and tasteless gas through destruction, decomposition and catalytic oxidation. In the decomposition process, high-energy high-ozone UV ultraviolet light beams are generated to decompose oxygen molecules in the air to generate free oxygen, namely active oxygen, and the free oxygen is required to be combined with the oxygen molecules because positive and negative electrons carried by the free oxygen are not balanced, so that ozone is generated. Ozone has strong oxidizing effect on organic matters, strong removing effect on malodorous gas and other pungent odors, and ultraviolet light also has the functions of disinfection and sterilization.

The active carbon is honeycomb block active carbon, which is a microcrystalline carbon material mainly made of carbon-containing materials, and has black appearance, developed internal pore structure, large specific surface area and strong adsorption capacity. The active carbon has a large number of invisible micropores and a large specific surface area, so that organic waste gas can be firmly adsorbed, and the active carbon can continuously adsorb the waste gas until the adsorption of the active carbon is saturated.
