Therefore, the pollution of the flue gas to the environment is the composite pollution of various poisons. The harmfulness of smoke to human bodies is related to the size of particles, most of the harmfulness to human bodies is floating dust with the diameter smaller than 10um, and particularly the highest harmfulness is the floating dust with the diameter of 1-2.5 um. The harm to the human body depends on the composition, concentration, duration and site of action of the contaminating substances on the one hand and on the sensitivity of the human body on the other hand. High smoke concentration can cause acute poisoning, manifested as cough, pharyngalgia, chest distress, asthma, headache, eye stabbing pain, etc., and severe cases can die. The most common is chronic poisoning, which causes irritation to respiratory mucosa to cause chronic bronchitis and the like.
Often contain the dust of a large amount of tiny granules in the flue gas, when carrying out flue gas treatment, generally carry out the interception processing to this tiny particle dust through the filter screen, but the filter screen space is setting up when less to and is blockked up, lead to the staff higher to the cleaning frequency of filter screen, influence the treatment effeciency of flue gas.
