Abstract

The invention discloses a flue gas purifying system and a method. The system comprises a feed bin, a reaction tower and a deduster, wherein, the feed bin is used for transporting the garbage to a garbage incinerator when the garbage amount meets the primary combustion amount of the garbage incinerator; the reaction tower is connected with the garbage incinerator by a pipeline to be used for the flue gas to react with the lime slurry ejected from a rotary sprayer; the deduster is connected with the reaction tower by the pipeline to be used for dedusting of the flue gas treated by the reaction tower. The system of the invention is high in safety, simple in operation, high in purification efficiency and durable in use.

Description

technical field [0001] The invention relates to flue gas purification technology, in particular to a flue gas purification system and method. Background technique [0002] Conventional waste disposal methods include landfill, incineration and composting. Garbage incineration has attracted much attention due to its advantages of complete harmlessness, short processing time, heat recovery and small footprint. The flue gas purification system is the key to the pollution control of waste incineration. After the flue gas is purified, the emission concentration of various pollutants should meet the requirements of the national standard GWKB3-2000. Flue gas purification generally consists of three parts: deacidification, activated carbon adsorption, and dust removal. The processes commonly used at home and abroad are mainly semi-dry method / dry method + bag filter, among which deacidification technology is the core of waste incineration flue gas purification system. [0003] At p...
