[0039]The daily processing capacity is 5 tons, and the waste is sent into the incinerator manually after simple sorting, and the material is fed intermittently. The whole set of equipment covers an area of ​​85 square meters, the temperature of the waste gas decomposition area is 800 ° C, and the waste combustion temperature is 1100 ° C. SO 2 Concentration 320mg / m 3 , NO x Concentration 300mg / m 3 , particle concentration 240mg / m 3 . Dioxin concentration was not detected at 1m of the factory boundary, SO 2 , NO x Particulate matter was not detected.

[0040] The daily processing capacity is 10t, and the garbage is simply sorted and sent to the incinerator through the conveyor. The whole set of equipment covers an area of ​​125 square meters, the temperature in the waste gas decomposition area is 950°C, and the waste combustion temperature is 1300°C. SO 2 Concentration 330mg / m 3 , NO x Concentration 380mg / m 3 , particle concentration 260mg / m 3 . Dioxin concentratio...

Abstract

The invention discloses a waste incineration flue gas treatment system which comprises an incinerator, a desulfurization/dedusting integrated device, an adsorption device, a deodorization device, a sewage tank, a sedimentation tank, a sand filtering tank and an alkaline liquid tank, wherein a gas outlet of the desulfurization/dedusting integrated device of the waste incineration flue gas treatment system is connected with a gas inlet of the adsorption device, a gas inlet of the desulfurization/dedusting integrated device is communicated with an exhaust port of the incinerator through a flue, and a sewage outlet is communicated with the sewage tank; a flue gas outlet of the adsorption device is connected with a flue gas inlet of the deodorization device; and a flue gas outlet of the deodorization device is arranged below a filtering layer of the sand filtering tank through a fan and an exhaust pipe. In the invention, the spray levels of a desulfurizing tower are effectively reduced to achieve an aim of lowering the height of the desulfurizing tower; and moreover, the dedusting effect can be effectively improved.

Description

technical field [0001] The invention belongs to waste incineration flue gas treatment technology, in particular to a waste incineration flue gas treatment system. [0002] technical background [0003] The problem of domestic waste has become the most urgent environmental problem to be solved, especially in remote areas, there is no good solution for domestic waste, and most of them are incinerated on site. Direct open burning of garbage will cause serious air and ecological environment pollution. [0004] The direct combustion of garbage will produce a large amount of toxic and harmful gases including sulfur and dioxin. This has seriously affected the safety of the living environment of the surrounding crowd, and will directly endanger the physical and mental health of the surrounding crowd. [0005] The flue gas produced by waste incineration contains a large amount of SO 2 and soot. Sulfur-containing compounds are oxidized during incineration, and most of them are SO ...
