Description
Technical field
This utility model belongs to environmental technology field, particularly relates to a kind of combustion refuse flue gas purifying equipment.
Background technology
Currently cause resident panic owing to combustion refuse produces 21 grades to cancer pollutant, owing to stink makes resident be strongly opposed to, buried polluted underground water again, causes municipal refuse to encircle a city, is the low bottleneck of urban development.
The pollutant that the vaporific flue gas that current combustion rubbish produces is carried secretly；The noxious pollutant produced including the burning plastics such as 21 grades to cancer pollutant and metal ion, stupid, hydrocarbon, footpath, particularly stink, make people to live in several kilometers of circumference.So combustion refuse become people live most concerned environmental condition be destroyed.So combustion refuse causes resident panic, along with urbanization, city is developed more the biggest, and urbanite is the most, and house refuse is the most, the development in city causes again surrounding city soil nervous, so landfill waste polluted underground water, country's principle does not allows, and landfill waste does not allows, combustion refuse causes resident panic, so processing rubbish to have become as the bottleneck of urban development.
Being at present solid particle due to 2, particle diameter is the most small, and in the droplet wrapped up by liquid in vaporific flue gas, the electrostatic precipitation best with current efficiency of dust collection or bag-type dust all can not be separated.The most calm just suspension, the technology the most do not separated and equipment.Burn vegeto-animal ash particle and the particle specific gravity such as stupid, hydrocarbon that burning plastics produce, footpath is lighter than water, in the technology the most do not separated,
The vaporific flue gas of combustion refuse belongs to frontier branch of science " multiphase flow " according to internationally recognized " multiphase flow " mathematical model；" Liu De loyalty formula ", the isolation of purified unique technical process of " multiphase flow " is to settle in flowing.Settling unique conditional in flowing is the sedimentation critical grain size that grain diameter have to be larger than flue gas flow rate.The calm just suspension of droplet carried secretly due to the vaporific flue gas of combustion refuse discharge, so the stink that droplet is carried secretly enters in air with vaporific fume emission, composing environment pollutes.
The particle diameter of heavy metal ion and 2 granules, less than the sedimentation critical grain size of flue gas flow rate, is discharged in air so being necessarily suspended in flue gas, and composing environment pollutes.
Owing to Plastics Combustion generation noxious substance is stupid, hydrocarbon, the random vaporific fume emission in footpath enter cooling in air and separate out particulate matter, owing to particle diameter is less than the sedimentation critical grain size of flue gas flow rate, so necessarily suspending in atmosphere, composing environment stains dye.
