Background

The garbage is a waste product which loses use value and cannot be utilized, and is an important link of material circulation. Is a solid, fluid substance that is not needed or useful. In densely populated large cities, waste disposal is a headache problem. It is common practice to collect and send the waste to a landfill for landfill treatment or incinerate the waste with an incinerator. Both create environmental protection issues and termination of overconsumption can further mitigate landfill saturation. Disposal of waste in landfill sites not only contaminates ground water and gives off odors, but also makes less and less area available for landfill in many cities. Incineration inevitably produces toxic gases, which harm organisms. Most cities are researching ways to reduce the production of garbage and encouraging resource reclamation.

The garbage classification is a necessary choice for realizing reduction, quality improvement and efficiency improvement, and is an important measure for improving human living environment, promoting fine management of cities and guaranteeing sustainable development. Can not classify garbage and directly reflect the ecological literacy and civilization degree of one person or even one city.

the desulfurization and denitrification multi-scene garbage treatment method comprises the following steps: the garbage to be incinerated is placed on the garbage conveyor belt 4, the garbage conveyor belt 4 conveys the garbage to the first-stage incineration support 16 inside the garbage incinerator 2, the combustion liquid flame spray nozzle air supply groove 26 supplies air to the combustion liquid flame spray nozzle 18, the valve at the combustion liquid flame spray nozzle 18 is opened and then is immediately ignited, the garbage inside the garbage incinerator 2 starts to be incinerated, the driving motor inside the bottom base 19 drives the rotating shaft 27 to slowly rotate, the rotating shaft 27 drives the first-stage incineration support 16 and the second-stage incineration support 17 to slowly rotate, and part of garbage on the first-stage incineration support 16 falls onto the second-stage incineration support 17 in the rotating process of the first-stage incineration support 16 and continues to be incinerated.

High-pressure chamber 5 is inside quick conveying gas to trachea B14, and inside gaseous dispersion of trachea B14 is inside the air duct A20 of the first 21 both sides of air current dispersion, through the inside quick gas blowing of trachea A20 to air current dispersion head 21, and the inside calcium carbonate powder of calcium carbonate holding tank 8 discharges from the discharge gate of calcium carbonate holding tank 8 bottom simultaneously, through the inside calcium carbonate dispersion shower nozzle 15 of waste incinerator 2 with the even spraying of calcium carbonate powder on the rubbish of burning.

Waste gas that burns the production in waste incinerator 2 passes through air duct 9 and carries to gas dispersion head 11, and gas dispersion head 11 sends the waste gas that the burning produced into the inside primary filtration case of exhaust-gas treatment mechanism 10 and filters, and waste gas after 24 filters through primary filtration case enters into the inside of secondary filtration case 23 through flow divider 12 and air duct 9 and filters, and the gaseous emission after final filtration.

The garbage disposal device is suitable for different garbage incineration, carries out desulfurization and denitration treatment on the generated flue gas in the garbage incineration process, and finally discharges the gas after twice treatment.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
