Method of common industry off-gas treatment

All sorts of emits into airy to contain contaminant gas floorboard that industrial waste gas points to to the fuel inside business plant area burns and arise in manufacturing process. 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 to a few commonIndustrial off-gas treatmentMethod, everybody needs to understand. The word that have fun at can look.

The harm with industrial healthy to human body waste gas: The 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.

The principle of industrial off-gas treatment has law of activated carbon adsorption, catalytic combustion law, catalytic oxidation law, soda acid to counteract a variety of principles such as law, plasma law. So, what distinction do these different industry off-gas treatment have? How should the enterprise choose correct and logical processing way? The actor defect of method of off-gas treatment of 5 kinds of common industry introduces in detail for everybody below.

1. Cover magic art

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.

We introduce method of common industrial off-gas treatment here, if you want to know more the method about industrial off-gas treatment, everybody can pay close attention to relevant perhaps data we.
