Description
Technical field:
The present invention relates to technical field of waste gas treatment, and in particular to star-like industrial waste gas handles island.
Background technique:
Industrial waste gas refers to that generate in plant area, enterprise fuel combustion and production process various are discharged into containing for atmosphere
There is the general name of contaminant gases.These exhaust gas have: VOCs (volatile organic compounds), carbon dioxide, carbon disulfide, vulcanization
Hydrogen, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist) lead mercury, beryllide, flue dust and industrial dust etc.,
It is discharged into atmosphere, air can be polluted.
Industrial waste gas has many harmfulness, is mainly manifested in following sections:
(1) to the harm of human body: main performance is respiratory disease and the mucosal tissues such as physiological function obstacle and eye nose
It is stimulated and illness, exhaust gas is entered in human body by the different approach such as respiratory tract, and some directly generates harm, and some is also
Cumulative effect more serious can be detrimental to health.
(2) to the harm of plant: make what hazard symptoms is not seen on plant leaf blade chlorisis or surface, but plant
Physiological function has been affected, and plant products is caused to decline, deterioration, or even can generate acute hazard to plant, makes to plant
Object leaf surface generates blemish, or directly makes leaf is withered to fall off, and especially sulfur dioxide, fluoride etc. are ten to the harm of plant
Divide serious.
(3) influence to weather and weather: influence of the exhaust gas to weather and weather is very significantly, to be mainly reflected in and subtract
Reach the solar radiation quantity on ground less, increase annual precipitation, lower acid rain, tropical island effect etc..
Industrial waste gas processing refers to that the exhaust gas generated specifically for industrial site such as factory, workshop advances in external discharge
Row pretreatment is widely used in chemical plant, Electronics Factory, printing house, spray to reach the work for the standard that national exhaust gas externally discharges

Change the pollution factors such as hydrogen, and open the chemical bond of volatile organic compounds after being in contact with VOC molecule, by a series of anti-
It answers, final production carbon dioxide and water etc. stablize harmless small molecule.Meanwhile oxonium ion can destroy the existence ring of bacterium in air
Border reduces interior space bacterial concentration, and charged ion can adsorb more than tens times of own wt of suspended particulate, heavy by being self-possessed
It lowers, to remove air suspension colloid, achievees the purpose that purify air.
8, above-mentioned bioanalysis is broadly divided into biofilter, bio-trickling filter, bacteria bed etc. according to its form.
Biofilter mainly includes humidifier and biological treatment device two parts, and the exhaust gas collected by air-introduced machine is through being humidified
Device pretreatment come (pretreatment having further include temperature adjust, removal particulate matter etc.) enter biological treatment device afterwards, in gas
Pollutant adsorbed from gas phase main diffusion to the moisture film of filler outer layer and by filler, final explanation is carbon dioxide, water etc.,
Treated, and gas is discharged from the top of biofilter, and the packing layer of biofilter is filtrate (such as soil, heap with adsorptivity
Fertilizer, active carbon etc.).
Bio-trickling filter main body is packed column, inside has one or more layers filler, filler surface is formed by microbiota
Several millimeters thicks biomembrane, the liquid of the nutrient solution containing soluble inorganic is uniformly sprayed on filler above tower, and liquid is from upper
And lower flowing, be then discharged and recycled by tower bottom, exhaust gas enters bio-trickling filter by tower bottom, during rising with it is wet
The biofilm contact of profit and be cleaned, purified gas is discharged by tower top.
Biotrickling filter is will to input bacteria bed bottom by pipeline after gas collection and humidification and it is made to be spread in soil
In earth, a variety of pollutant components are adsorbed in soil particle surface after being dissolved in water in exhaust gas, through after a period of time on soil particle surface
The microorganism for harmful substance in the exhaust gas can be gradually turned out, and can be constantly by this substance decomposition, completion is handled, and filter bed is filled out
Sponge, dry bark, hay, wooden slag, shell, shell and its mixture etc. can be used in material.
9, above-mentioned blower is selected explosion-proof type blower (conveying has explosion and inflammable gas), coal dust because handling medium requirements
Blower (pulverized coal conveying), corrosive resistant fan (conveying has etchant gas), high-temperature blower (high temperature applicationss work or conveying high-temperature gas),
