Device for preventing generation of dioxin in refuse burning device

Abstract

Aiming to prevent his production of dioxins in waste burning, the invention comprises an extendable pipe that speeds up the air flow and connects in series with the exhaust pipe of the No.2 burning chamber, with top and bottom ends of the extendable pipe connecting with the exhaust pipe and the spray tower flange. The double layer structure extendable pipe has inner layer with extendable pipe 4, and the outside layer with a cylindrical tube 3 of same caliber with that of the exhaust pipe of the No.2 burning chamber. At the extendable neck, there are 2-4 fountain heads going through the cylindrical pipe 3 and the extendable pipe 4. It can spray cooling water when the smoke goes to the extendable neck speeding up dramatically, reducing temperature of the 1100DEG C high smoke to that below 200DEG C, effectively avoiding the regeneration of dioxins and protecting the environment.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to an anti-dioxin generation device in garbage incineration equipment. Background technique [0002] With the development of the economy, the amount of hazardous waste such as medical treatment, chemical solid waste and liquid waste has also increased sharply, posing a direct threat to human health. The rotary kiln incineration treatment technology is more suitable for the treatment of solid toxic pollutants, but the traditional rotary kiln incineration technology usually uses atomized water spray cooling method when the high-temperature incineration flue gas passes through a large tank. The cooling speed is slow, and it is easy to cause the flue gas to synthesize dioxins during the cooling process. There was a sample survey report on the pollutant discharge status of domestic waste treatment and disposal facilities in 47 key cities across the country. The standard rate o...
