Method using new S-N retardant to have control over dioxin generation in waste incineration

Abstract

The invention relates to the dioxin emission control technology in the process of solid waste treatment through the incineration method, and provides a method using new S-N retardant to have control over dioxin generation in waste incineration. The method using the new S-N retardant to have control over dioxin generation in waste incineration comprises the specific step that the new S-N retardant and garbage are mixed and are thrown into an incinerator to be burnt, or, firstly the garbage is thrown into the incinerator to be burnt, and then the new S-N retardant is directly ejected to a flue area of the incinerator to prevent the burning garbage from generating dioxin. The new S-N retardant can prevent the dioxin from being generated more efficiently, and cannot have negative impact on an incineration system and emission of other normal pollutants in tail portion flue gas. The new S-N retardant is wide in source and low in price, and has significant application value in solving the problem of emission of the dioxin in the process of waste incineration.

Description

technical field [0001] The invention relates to a technology for controlling dioxin discharge in the process of disposing solid waste by incineration, and in particular to a method for using a novel S-N blocker to control the generation of dioxin in garbage incineration. Background technique [0002] Solid waste incineration disposal method has gradually become the main way of solid waste disposal due to its advantages of reduction, harmlessness and resource utilization. With the rapid development of my country's economy, the output of garbage is increasing day by day, and land resources are becoming increasingly scarce, so the harmless disposal of garbage is particularly important. However, the harmless disposal rate of waste in my country is not high at present, especially incineration disposal. Therefore, the national government departments attach great importance to the harmless disposal of garbage. The "Twelfth Five-Year Plan" clearly states: "By 2015, the rate of harm...

Problems solved by technology

If the inhibitory effects of sulfur-containing blockers and nitrogen-containing blockers can be brought into play at the same time, the above shortcomings can be made up for, but at present, there are almost no development and application of blockers containing sulfur and nitrogen elements at the same time.
