Double temperature double bed gasification, oxidization and fluidized bed incinerator for disposing high concentration organic effluent liquor

Abstract

The utility model relates to a double-temperature double-bed gasification and oxidation fluidized bed incinerator for treating high-concentration organic waste liquid, which relates to a fluidized-bed incinerator for treating high-concentration organic waste liquid. The other end of the low-temperature flue 21 of the present invention is connected to the high-temperature oxidation circulating fluidized bed 60, and the two ends of the high-temperature air pipeline 30 are respectively connected to the high-temperature air preheater (15) and the low-temperature gasification fluidized bed 50. The combination of low-temperature gasification of low-temperature gasification fluidized bed and high-temperature combustion of high-temperature oxidation circulating fluidized bed in the present invention solves the problem of agglomeration and coking of fluidized bed materials, and effectively removes HCl and SO2 produced after incineration of high-concentration organic waste liquid Harmful gases such as NOx and NOx fully suppress the generation of dioxin in the furnace, and can completely incinerate the toxic organic substances in the waste liquid, and the incineration removal rate reaches more than 99.99%. The device almost solves all the problems encountered in incinerating high-concentration organic waste liquid in a fluidized bed.

Description

Technical field:

[0001] The invention relates to a fluidized bed incineration device for treating high-concentration organic waste liquid, in particular to a device for treating various toxic and harmful high-concentration organic waste liquids by combining low-temperature gasification of a fluidized bed and high-temperature oxidation of a circulating fluidized bed. Background technique:

[0002] In recent years, with the rapid development of my country's economy, the production and discharge of high-concentration organic waste liquid has increased year by year, and the high-concentration organic waste liquid produced by the petroleum, chemical, pharmaceutical, printing and dyeing and paper industries reaches tens of millions of tons every year. High-concentration organic waste liquid is one of the main sources of water pollution. Its indiscriminate discharge seriously damages the ecological environment and threatens human health. Since a considerable part of the high-concen...
