The utility model has the advantages that: reasonable in design, adsorption area is big, and cost is low, efficient, and the life-span is long, has solved big air quantity (especially big air quantity, low concentration) industrial waste gas and has administered a difficult problem, and its air quantity can reach 10000-160000m
3/ h, in addition higher.The utility model still can be used in big flow purifying of drinking water processing and the sewage disposal system except that being used for big air quantity waste gas pollution control and treatment.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is a kind of big air quantity waste gas pollution control and treatment adsorption tower of the present utility model.
Fig. 2 is for inhaling the cross-sectional view that takes off jar among Fig. 1.
Fig. 1 has described an embodiment of the present utility model.Comprising in this example that two (or a plurality of) inhale takes off a jar 6a, 6b, activated carbon fiber adsorption column 4a, the 4b that 7 (or other suitable quantities) are housed in a jar 6a, the 6b housing taken off in each suction, like this can be under same volume, increase the area of adsorption layer greatly, thereby adapt to the requirement of big air quantity circulation, do not blow bad adsorption layer or reduce adsorption efficiency and the reason velocity of liquid assets is too high.Filter course 3a, 3b were arranged, filtering out solid-liquid materials such as dust in the waste gas, oil, glue, to prevent that these materials are attached on the activated carbon fiber and reduce absorption property before adsorption column 4a, 4b.Foul on filter course 3a, the 3b is wanted periodic flushing, makes it to be discharged by blowoff valve 14a, 14b, and filter course 3a, 3b are by formations such as metal framework and interior paper thereof, chemistry (synthesizing) fiber, metallic fibers.
In adsorption column 4a, 4b outlet dividing plate 5a, 5b are arranged, adsorption column 4a, 4b are evenly distributed in jar, and make between adsorption column 4a, 4b and dividing plate 5a, 5b and seal, in case gas is without adsorption layer but directly discharged by the gap.Adsorption column 4a, 4b are the cylinders that is rolled into by wire netting, and outsourcing is formed with certain thickness active carbon fiber felt, and its thickness can be between 10-200mm.Certainly, adsorption column also can adopt other suitable versions, and active carbon fiber felt also can replace with other suitable active-carbon fibre materials.According to the different active carbon fiber felt of kind, the selection of the harmful substance in the waste gas (solvent), to compounds such as the fragrant same clan (benzene,toluene,xylene, styrene), ketone, ester class, alcohols, petroleum-type, nitrogen, can adopt viscose base activated carbon fiber, its specific area should be at 1000-1500m
2In the scope of/g, inhaling benzene should be in 30-58% scope; Should adopt the polyacrylonitrile based activated carbon fiber to materials such as compounds such as sulphur etc., nitrogen and stench, ozone, its specific area should be at 500-1100m
2In the scope of/g, inhale benzene in 18-40% scope.
Make adsorbent owing to adopt activated carbon fiber, its suction takes off that speed is fast, adsorption capacity is big, particularly low concentration solvent adsorption efficient is much higher than activated carbon, after inhaling repeatedly, taking off, the absorption property of activated carbon fiber is almost constant, thereby long service life, this device has efficiently, the characteristics of high life thereby make, and particularly has more obvious superiority aspect the waste gas of administering big air quantity, low concentration.The terminal valve of being administered gas (two big valve 2a, 7a and 2b, 7b), and the control valve of desorption gas (steam) (two little valve 8a, 9a, and 8b, 9b) are equipped with in the two ends that a jar 6a, 6b are taken off in suction, during absorption, close two little valves, open two big valves, then waste gas enters to inhale and takes off jar, behind activated carbon fiber adsorption column 4a, 4b, harmful substance (solvent) is adsorbed, and becomes cleaned air by the gas of discharging in the middle of adsorption column 4a, the 4b.During desorption, close two big valves, open two little valves, then desorption gas (steam) is entered by the centre of adsorption column, by acf layer, solvent is deviate from, and flows into condenser 10 through valve 9a, 9b then.
Each is inhaled and to take off jar by the pipeline parallel connection, and it is with a cover air-introduced machine 1, cold doubtful device 10, separator 12, and waste gas is sucked by air-introduced machine 1, jar becomes cleaned air through inhaling to take off; During desorption, concentrate and in condenser 10, be condensed into liquid through the solvent of high-temperature steam desorption through activated carbon fiber, through valve 11 at separator 12 internal solvents and water stratification, release moisture content after, be solvent, thereby reach the purpose that reclaims solvent.For water-soluble solvent, need distillation; Need fractionation and rectifying for mixed solvent.
By valve control, jar is taken off in each suction two kinds of working methods: a kind of is that all jars adsorb (open all big valves this moment, closes all little valves) simultaneously, carries out desorption (close all big valves this moment, opens all little valves) then simultaneously.Another kind of working method is jar to be taken off in all suctions be divided into two groups, and wherein one group adsorbs, and another group is carried out desorption, and alternate repetition carries out then, always continuous operation.By selecting different working methods and suction to take off the time, can adjust the total amount of discharging the remaining concentration of narmful substance in the gas better, make it to reach discharge standard.
Determining of adsorption time reach discharge standard and activated carbon fiber not adsorb saturated as yet be principle to discharge gas, and its adsorption time can roughly be chosen in 10-240 minutes; Definite the reaching more than 95% with the activated carbon fiber removal efficiency of desorption time is principle, desorption gas temperature height, and desorption time is short; The desorption gas temperature is low, then needs desorption time long, and when desorption gas (steam) temperature during at 120 ℃-150 ℃, its desorption time should be at 10-30 minutes.
A among Fig. 1 is the waste gas that enters, the clean gas of B for discharging, and C is the steam that enters, the solvent of D for discharging.
