Description
Technical field
It the utility model is related to exhaust-gas treatment field, and in particular to off-gas cleaning equipment.
Background technology
Waste gas purification (Flue gas purification) is primarily referred to as industrial waste gas caused by industrial site such as
The work that dust particle, flue gas flue dust, gas with foreign flavor, toxic and harmful gas are administered.Common waste gas purification has factory
Fume and exhaust gas purifying, workshop dust waste gas purification, organic waste-gas purification, the purification of waste gas peculiar smell, acid-base waste gas purifying, chemical emission
Purification etc..
Off-gas cleaning equipment is commonly utilized in chemical plant, Electronics Factory, spray painting factory, automobile factory, coating factory, petrochemical industry row
Industry, Furniture Factory, food factory, rubber plant, plastic cement factory etc. produce peculiar smell, stink, the industry of toxic and harmful gas.
The gaseous species that off-gas cleaning equipment mainly purifies have benzene,toluene,xylene, ethyl acetate, acetone butanone, second
The acid-base waste gas purifyings such as the organic exhaust gas such as alcohol, acrylic acid, formaldehyde, hydrogen sulfide, sulfur dioxide, ammonia and organic waste-gas purification.Waste gas
Mainly active charcoal waste gas purification absorption method, medicament absorb method for treating exhaust gas, the catalysis burning waste gas method of purification, heating power to purification method
The burning waste gas method of purification, plasma waste gas cleaning method etc..During from exhaust gas purifying method, expense should be selected as the case may be
It is low, power consumption less, non-secondary pollution, as far as possible accomplish save energy consumption, it is environmental.Such as, waste gas purification industry typical flat -- on
The CHO-91 Tower for purifying waste gas of Hai'an Ju Le bio tech ltd production uses five heavy waste gas adsorption filtration cleaning systems, gives up
Gas Depurative design is careful, purification filtering waste gas layer by layer, once successfully undertakes the construction of the purification of Olympic Games racing boat lacquer spraying waste gas, effect is preferable.
Tower for purifying waste gas typically has acid mist Tower for purifying waste gas, Waste gas purifying column made of glass fibre reinforced, biological Tower for purifying waste gas, PP sprays
Tower for purifying waste gas etc..The soda acid exhaust-gas treatment of waste gas treatment equipment（Spray column）Main function mode be continuous acid mist waste gas by
Airduct introduces purifying column, and by packing layer, waste gas carries out gas-liquid two-phase with sodium hydroxide absorbing liquid and fully contacts absorption neutralization instead
Should, acid mist waste gas is discharged into air after purification, then after demisting plate dehydrating demisting by blower fan.Absorbing liquid increases in bottom of towe through water pump
After pressure tower top spray and under, be finally back to bottom of towe recycling.Acid mist waste gas after purification reaches the discharge of Guangdong Province place
The emission request of standard, less than discharging standards.
During waste gas purification, dust granules big in waste gas should be intercepted filtering first, pass through scrubbing tower again afterwards.
During dust granules filter, if the excessive velocities that waste gas passes through, cause waste gas filtering not thorough, cause filtering
Effect is bad；In addition, the spray structure in scrubbing tower only has independent one layer, makes washing process not thorough, causes waste gas purification
Not exclusively；Produce waste gas in the industry simultaneously, be all high-temperature gas after dust granules filtering, into before scrubbing tower such as
Fruit by mercury dropped, then can not influence whole clean result.
