Method of industrial off-gas treatment reachs the harm value to the person

Industrial waste gas is a kind of pollution gas that endangers people life health at any time, these waste gas have: Hydrogen of oxide of hydrogen of carbon of carbon dioxide, 2 vulcanization, vulcanization, fluoride, nitrogen, chloric, chloridize, carbon monoxide, vitriolic (mist) plumbic mercury, Beryllium changes dust of content, soot and productivity, emit into atmosphere, can pollute air. Inside the system that these material enter a person through different way respiratory tract, some produces a harm directly, some still has save up effect, those who meet more serious harm person is healthy. Different material can have distinct effect. So small making up what want the introduction next isIndustrial off-gas treatmentReach the harm to human body.

　　One, the harm of industrial waste gas to human body

1. person needs to breathe air in order to maintain life. An adult breathes everyday about 20 thousand for many times, induction air amounts to 15 ～ 20 stere. Accordingly, the air that was polluted has immediate effect to human body health. Air pollution content is many sided to the harm of human body, main show is respiratory tract disease and physiology dysfunction, and the mucous membrane organization such as eye bazoo is stimulated and sicken.

2. Air pollution content is many sided to the harm of human body, main show is the mucous membrane such as respiratory tract disease and physiology dysfunction and eye bazoo the organization is stimulated and sicken.

For instance, the fuliginous mist event that London of 8 days of England produced 5 ～ in December 1952 dies 4000 people. People calls this catastrophic aerosol ” of ” bloodguilty aerosol. According to the analysis, because calm of honest of that a few the natural bonds and ethical relationships between members of a family is misty,this is, factory chimney and dweller warm oneself the waste gas soot of eduction diffuses in prolonged of London urban district not to come loose, highest chroma amounts to soot 4.46 milligram / rice 3, average concentration reachs the day of 2 oxidation sulfur unexpectedly 3.83 milliliter / rice 3. 2 oxidation sulfur passes some kind of chemical reaction, generate vitriolic fluid foam to adhere to go up in soot or agglomeration is on droplet, enter an organ along with breath, make the person comes on or quicken the death of chronic patient.

3. Ill other people is mixed through respiratory tract in industrial waste gas after the skin enters human body, system and the organ such as the breath that can give a person, blood, liver cause provisionality and permanent pathological change, especially benzene and Bi many kinds annulus aromatic hydrocarbon can make human body sends cancer to take seriously in order to cause human height directly.

4. Although atmosphere is medium contaminant concentration is not high, but the air that human body breathed this kind of pollution year in year out, also can cause chronic the disease such as asthma of bronchitic, bronchus, emphysema and lung cancer.

　2, the actor defect of method of common industry off-gas treatment

1. cover

Principle: Use more intense sweet smell and bad smell to mingle, with cover bad smell, can be received what make.

Suitable scope: Apply to need instantly the circumstance that the ground, momentarily eliminates body of low density evil bad smell to affect, effluvial intensity 2.5 the left and right sides, without constituent source.

Advantage: Can remove effluvial effect as soon as possible, flexibility is big, fare is low.

Defect: Effluvial composition is done not have by purify.

2. Dilute diffuses law

Principle: Through chimney frowziness gas the platoon comes atmosphere or with without foul air dilute, reduce effluvial material concentration in order to reduce a stink.

Suitable scope: Apply to the effluvial gas that handles medium, low pH indicator to the organization is discharged.

Advantage: Charge low, equipment is simple.

Defect: Easy be deceived resembles a condition to restrict, effluvial matter still exists.

3. Law of heating power combustion and catalytic combustion law

Principle: Effluvial below high temperature material and fuel enrage sufficient mix up, realize catalytic combustion.

Suitable scope: Apply to the flammability gas that handles high concentration, persnickety volume.

Advantage: Purify efficiency tall, effluvial material is oxidized to decompose.

Defect: Equipment is perishable corrode, consume fuel, processing cost is high, easy form pollution 2 times.

4. Water absorbs a law

Principle: Some of some material easy dissolve in using bad smell the character at water, make bad smell composition is contacted with water directly, dissolve thereby achieve deodorization goal at water.

Suitable scope: The water-solubility, effluvial gas that has constituent source.

Advantage: Craft is simple, management is convenient, low yield of equipment movement charge gives birth to pollution 2 times, need to undertake handling to catharsis fluid.

Defect: Purify efficiency low, answer to be used jointly with other technology, mellow to sulfur, the processing effect such as fatty acid is poor.

5. Medical fluid absorbs a law

Principle: In using bad smell, certain material and medical fluid produce the character of chemical reaction, purify is certain bad smell composition.

Suitable scope: Apply to bad smell of pH indicator of processing air quantity, high school.

Advantage: Can specific aim handles part of certain bad smell, craft is more mature.

Defect: Purify efficiency not tall, use up absorbefacient, easy form and pollute 2 times.

Above is the harm of industrial waste gas to human body and method of industrial off-gas treatment, hope everybody looks to be able to understand this respect somewhat. If still think understanding is more and relevant,information can seek advice from our official net.
