[popular science] does off-gas treatment of different type industry need what to problem note?

Develop as industrial high speed, the air pollution that the waste gas place that industry arranges causes is more and more serious. Industrial waste gas basically has oxide of hydrogen of carbon of carbon dioxide, 2 vulcanization, vulcanization, fluoride, nitrogen, chloric, chloridize hydrogen, carbon monoxide, vitriolic (mist) , the benzene such as flue gas, dust, acetone, fourth ketone, benzene, toluene, xylene is content organic waste gas. Industrial waste gas serves as the main source of air pollution, processing of industrial waste gas is attached most importance to especially should, the technology that manufactures as a result of the factory is different, the sort of waste gas contaminant that industrial waste gas produces is different also, in the light of different type waste gas contaminant should use different off-gas treatment technology, small today make up introduce off-gas treatment of different type industry to need to note what problem for everybody.

　　Different typeIndustrial off-gas treatmentNeed notes a problem

Type of industrial off-gas treatment can divide the processing to can burn gas roughly, support combustion the aeriform processing, processing of noxiousness gas, processing of inert gase.

　　 One, the processing that can burn gas

(1) can burn gas discharge, if discharge capacity is larger, answer to choose the person’s little place as far as possible, prohibit all round the attention fire, and the fire extinguisher with corresponding stock, sand and water.

(2) in discharging steel bottle can burn gas, the staff member should stand in the flank of gas outlet to undertake operating, in case gas is ejective injure a person.

(3) when using catalytic combustion law to handle, should install pressure-relief valve, control can light angry speed, make gas is given off slowly as far as possible, made sufficient inside burner combustion is dropped.

　　 2, support combustion aeriform processing

(1) the powder that get on stick together in container valve or uses appliance to go up, oil kind, grease kind reach flammability material, after the bottom is cleared and clean, fang Kejin supports combustion to be handled angrily all right.

(2) forbidden support combustion gas and can light gas to be in same place undertake handling near its, with the happening of accident of explosion proof blast.

(3) support combustion in processing of gas all round, should not have igneous cause, mix without combustion content explode easily article.

　　 3, the processing of noxiousness gas

(1) when handling noxiousness gas, the staff member must wear the fatigue protection such as respirator, glove to provide the personnel that has nothing to do with processing job, off-limits mephitis handles an area.

(2) discharge a few noxiousness gas directly to the middle of atmosphere, after classics concerned department agrees, must choose as far as possible devious place undertakes, control discharges the chroma of exit to answer dilute arrives allow to discharge chroma the following.

(3) the absorbefacient that uses in noxiousness gassing and sorbent, should ensure its effectiveness just can be used.

　　 4, the processing of inert gase

Although inert gase does not have dangerous sex, but assemble of many inert gase, can make all round oxygen content decreases, make the person chokes thereby.

(1) discharge in the proper place outdoor.

(2) the bottle that be like steel or instrument indoors, can receive on exhaust is tracheal, make its are brought outdoor slow discharge.
