Description
Technical field
The utility model relates to filed of flue gas purification, specifically, relates to a kind of purifier of bitumen flue gas.
Background technology
Can produce a large amount of bitumen flue gas in the production process of carbon element green anode.Mainly contain adsorption, small part straight-chain hydrocarbons and water vapour in pitch class flue gas, wherein contain 3, the carcinogens such as 4-BaP discharge directly that atmosphere pollution is large, peculiar smell is heavy, therefore must purify qualified discharge.
Domestic and international purification method to bitumen flue gas mainly comprises burning method, Electrostatic method, absorption cleaning method and adsorption cleaning method at present.
Burning method is that the combustible that will contain in glance coal contacts with air at a certain temperature and burns.The people such as poplar is real, Ningde is first disclose a kind of method of efficient processing bitumen flue gas in Chinese invention patent CN201010101050.0: utilize the rear flue gas of forging of rotary kiln after-burner, make the bitumen flue gas that Green anode making produces pass through the rotary kiln after-burner, tar, polycyclic aromatic hydrocarbon in the rotary kiln after-burner in bitumen flue gas decompose, burn, and effectively remove stupid and the harmful substance such as pyrene.Although this technology can make the bitumen flue gas that Green anode making, asphalt melting produce be purified in the burning of rotary kiln after-burner, has removed harmful substance---BaP fully, from operating cost aspect consideration, not too economical.
In the Electrostatic method, the arresting efficiency of dry type electric fishing set pair gaseous component is no better than zero, although and wet type electric fishing storage can trapping gaseous pitch, increased the trouble that sewage disposal brings, cause this method investment large, the maintenance and management technical sophistication.
The absorption cleaning method is a kind of industrial waste gas improvement method commonly used.It is the difference of utilizing each blending ingredients solubility in selected absorbent (gasoline, diesel oil etc.) in waste gas, and perhaps in certain component and absorbent, active component reacts, and reaches a kind of method of purifying exhaust air.The absorption cleaning method is applied to bitumen flue gas and administers, and exactly gaseous contaminant in flue gas is transferred to liquid phase (absorbent), thereby is reached the purpose of purifying smoke.This method equipment is simple, easy to maintenance, and SR is little, and energy consumption is low, and shortcoming is to be only applicable to the high concentration occasion, and general purification efficiency is at 70%-80%.
The adsorption cleaning method is with porosu solid (absorbent filter medium), one or more components in fluid (gas or liquid) mixture to be gathered or condensing on the surface, reaches a kind of method of operating of separating purpose.In the purification adsorption process of bitumen flue gas, selecting suitable absorbent filter medium is one of key of adsorption cleaning method.Generally should have following characteristics as absorbent filter medium: have larger adsorption capacity, namely absorbent filter medium should be the solid foam that loosens; Have good selective, in order to reach the purpose that purifies one or more pollutants; Have good reproducing characteristic and abrasive resistance, the adaptability to acid, alkali, water, high temperature is arranged.The capital equipment of bitumen flue gas adsorption cleaning method is the fixed-bed type absorber, is generally the cylindrical vertical structure, and built-in lattice plate or orifice plate are placed filtrate on it, and bitumen flue gas is by passing through in container, passes the filtrate gap, discharges or enter next process after absorption.
