Description

High humidity condensation flue gas microparticle remover and removal methods
Technical field
The present invention relates to a kind of high humidity condensation flue gas microparticle remover and removal methods, belong to field of environment protection equipment.
Background technology
At present, environmental problem caused by industrial production is outstanding day by day, and haze weather happens occasionally, and has had a strong impact on people's Quality of life and health.When haze is mainly industrial smoke discharge, the suspension such as contained fine particle in flue gas Removing does not cause thoroughly, how can be to prevent to the progress of the suspensions such as various flue gas fine particles and real effective and thorough removing The Main Means that haze weather occurs, and environmental technology field urgent problem to be solved.
Following technical scheme is mainly taken in terms of dust pollution is prevented at present;
1. sack cleaner is easily processed to the flue gas that do not condense, but the processing of the inadaptable flue gas that condensed to high humidity.Flue gas wet method takes off After sulphur, humidity of flue gas is big, temperature is low and carries the suspension such as gypsum droplet and fine particle, and also other high humidity low temperature are containing thin The flue gas of microparticle suspension, condensation is formed when passing through filter bag into deduster under low-temperature condition.The generation of dew condensation phenomenon, The aggregation of grain thing causes pocket to block, and dust layer pulp, filtrate can not be removed by sticky, and resistance of the filter bag sharply increases, until Stomata, which blocks, makes deduster not run.
2. although wet dust removal technology can condense to high humidity to a certain extent, flue gas is effectively treated, technique Equipment is huge, and equipment investment amount is big, maintenance cost is high.Wet cottrell efficiency in the running of reality only has 70% or so, want to reach current its smoke inlet dust concentration of minimum discharge 5mg/m3 standards no more than 18mg/m3, Want to reach " near-zero release " difficulty larger.
In summary, how to design it is a kind of it is simple efficiently, can be to various containing fine particle suspension high humidity condensation Flue gas is thoroughly handled, and can realize that the equipment of " near-zero release " is art personnel's urgent problem to be solved.
The content of the invention
Can be to various high humidity knots the present invention relates to a kind of high humidity condensation flue gas microparticle remover and removal methods, the remover Reveal the fine particle suspension that flue gas carries to implement thoroughly to remove, the flue gas fine particle suspension content after removing can be realized " near-zero release ", present apparatus small volume, treating capacity are big, removal efficiency is high, small investment, energy consumption are low.
