A special filter bag for waste incineration

Abstract

The invention discloses a special filtering bag for refuse burning. The filtering bag comprises a filtering bag body and a mounting ring which is used for fixing the filtering bag body on a smoke exhaust port of a waste incinerator; the filtering bag body comprises an innermost insulating layer and an outmost protective layer, between which a water absorption layer made from materials with good water absorptivity is arranged; partially in contact with external water, the water absorption layer is moistened; packing layers are arranged on two sides of the water absorption layer in a cross-linked manner and are made from cross-linked cotton fibers and active carbon particles in the cotton fibers. When the filtering bag is used, the water absorption layer is in contact with water so as to moisten both the water absorption layer and the packing layer; dioxine in flue gas is dissolved in water when passing through the structure, and then is subjected to centralized collection and treatment rather than being discharged into the environment; with the active carbon particles in the packing layers, the adsorption to fine floating objects in flue gas can be greatly improved, thereby improving the adsorption and cleaning effects.

Description

technical field [0001] The invention relates to a filter bag used in the field of filtration, in particular to a special filter bag for garbage incineration. Background technique [0002] With the development of industry and science and technology, people's daily necessities are increasingly abundant, but at the same time it also brings a lot of garbage. These wastes not only occupy a large amount of land, causing air, soil and water pollution, but also produce various bacteria and pathogens, which seriously endanger human health. [0003] Garbage incineration is a treatment method of garbage. Combining garbage incineration with high temperature (1650-1800°C) thermal decomposition and melting treatment is convenient for landfill, saves land, and can also eliminate various pathogens. Modern garbage incinerators are all Equipped with a good smoke and dust purification device to prevent air pollution, but it cannot effectively eliminate or reduce the emission of highly toxic s...
