Problems solved by technology

However, there is no suitable and practical incinerator technology to choose from. At present, the domestic waste in these areas is basically landfilled or stacked in the open air, or even not collected at all and discarded anywhere.

Embodiment Construction

[0050] Such as Figure 1 to Figure 10 As shown, a domestic waste incineration system for preventing and controlling flue gas pollutants, including a solid matter treatment system, ash and dust treatment system and a gas treatment system;

[0051] 1. The solid matter treatment system includes a garbage storage warehouse A2, a compression crushing system A3, a drying system A4, a conveying system and an integrated incinerator A5;

[0052] 1. Garbage crushing and drying:

[0053] The garbage enters the garbage storage warehouse A2 from the transport vehicle entrance 58 through the weighbridge room A1. A grab rail 60 is installed above the garbage storage warehouse A2. The grab bucket 59 is connected to the grab bucket rail 60. The compression crushing system A3 is located in the garbage storage warehouse A2. Among them, the grab hopper 59 grabs garbage from the garbage filling pit 61 and feeds it into the compression and crushing system A3. The compression and crushing system A3...

Abstract

The invention discloses a domestic refuse incineration system for preventing and controlling flue gas pollutant. A material grabbing hopper of a refuse storage vault feeds materials into a compressionand crushing system, the compression and crushing system is connected with a drying system through a conveying system, a refuse discharging opening of the drying system is connected with a refuse feeding opening of an integrated incinerator, a hot bad smell outlet of the drying system is connected with an air inlet of the integrated incinerator, a combustible gas outlet and a flue gas discharge opening of the integrated incinerator and a hot air outlet of a second-stage heat exchanger are connected with a second combustion chamber, and the second combustion chamber, a first-stage heat exchanger, a quick cooling chamber, the second-stage heat exchanger and a flue gas desulfurization device are connected in sequence; and a hot air outlet of the first-stage heat exchanger is connected to anair inlet of the drying system. The domestic refuse incineration system is rigorous and reasonable in structure, the flue gas pollutant can be prevented and controlled in key processes including refuse drying, gasification burnout, flue gas burning purification and flue gas cooling, heat energy, combustible gas and combustion-supporting air needed by the system in all processes are provided, and the direct cost is almost zero.

Description

technical field [0001] The invention belongs to the technical field of garbage incineration, in particular to a method for preventing and controlling flue gas pollutants and a domestic garbage incineration system. Background technique [0002] Domestic waste is considered one of the better methods of domestic waste disposal due to its significant reduction, thorough harmlessness and relatively easy control, waste heat recycling, relatively small footprint, and sustainable use, but the key points of waste incineration The control and treatment of pollutants, especially dioxin-like highly toxic substances, meet the national emission standards. The dioxin-like harmful substances contained in the incineration of domestic waste are mainly produced by the incineration of organic matter containing chlorine in domestic waste, and exist in the flue gas in a gaseous state or attached to the smoke. Dioxins are highly toxic and carcinogenic. It is solid in the standard state, with a me...
