Description
Technical field
The present invention relates to a kind of activating apparatus of spherical activated carbon, relate in particular to the mobile tower of a kind of vertical type, it is used for the activating and regenerating of fluidized floating bed adsorption system spherical activated carbon.
Background technology
Traditionally, utilize the adsorption material of high porosity, high-specific surface area, by the adsorption method for purifying technology of suction-operated removal VOC (Volatile Organic Compounds, VOCs), the general adsorption systems of using fixed beds more; And the ADSORPTION IN A FIXED BED system criticizes the formula mode of operation by two towers or multitower, carry out the absorption of waste gas and adsorb regneration of adsorbent material after saturated, only when the VOCs that meets high response processes, the chemicals that Chang Yin is adsorbed is in when absorption and adsorption material generation catalyst exothermic oxidation reaction (for example ketone and active carbon adsorption material), cause the not good and a large amount of hot polymerization collection of fixed bed internal heat dissipating, and then carbon bed fires or blast problem occur; So, in order to improve this shortcoming of ADSORPTION IN A FIXED BED system, and develop a kind of fluidized floating bed or be called for short adsorption system or honeycomb zeolite runner inspissator (Rotary Type Concentrator) the collocation incinerator system of fluidized bed (Fludized Bed).
Moreover, the adsorption process of known fluidized floating bed adsorption system as shown in Figure 1, waste gas is sent into the bottom of an adsorption tower 10 from an air flow inlet 13 with a blower fan 14, and after off-gas flows disperses by an air-flow dispersion plate 12, with by on the spherical activated carbon 30 that falls contact, namely can be used to purifying exhaust air and from air stream outlet 15 dischargings of cat head this through Purge gas; Wherein, the inside of this adsorption tower 10 is separated into several layers by a plurality of porous plates 11, and this spherical activated carbon 30 falls via the top of this adsorption tower 10, and above these porous plates 11, form the fluidized floating layer, and fall along these porous plates 11 peristome in layer, when this spherical activated carbon 30 contacts with the waste gas that contains VOCs, the VOCs in the waste gas is adsorbed in the hole of spherical activated carbon 30, waste gas namely becomes the Purge gas discharging; Yet, after the spherical activated carbon 30 behind the absorption VOCs drops down onto the storage tank of these adsorption tower 10 bottoms, be transported to follow-up desorption program by an adsorption material conveying device 20, after carrying out desorption and regeneration work, send the top of this adsorption tower 10 back to.
Secondly, the desorption flow process of this fluidized floating bed adsorption system is shown in Fig. 1 right-hand part, after spherical activated carbon 30 behind the absorption VOCs drops down onto the storage tank of these adsorption tower 10 bottoms, carry source of the gas 22 by one of this adsorption material conveying device 20, form propelling movement power with its air of being sent or nitrogen, carry adapter 23, transfer pipeline 24 and second to carry adapter 25 to deliver to the top of desorption column 40 via discharge nozzle 21, first, carry out the work of desorption and regeneration; Spherical activated carbon 30 behind the desorption and regeneration then carries adapter 26, the 4th to carry adapter 27 and feed pipe 28 to send the top of this adsorption tower 10 back to the 3rd.
Wherein, the spherical activated carbon 30 for the treatment of desorption and regeneration is slowly down piled up in a desorption reaction device 41 of this desorption column 40 and is flowed, and via a desorption thermal source 42 heating, be blown into nitrogen by the desorption source of the gas 43 of these desorption column 40 belows again and contact with this spherical activated carbon 30, with the VOCs desorption in this spherical activated carbon 30; Spherical activated carbon 30 behind the desorption is sent this adsorption tower 10 upper ends back to by above-mentioned conveying flow process behind these desorption column 40 bottom coohngs, adsorb once again VOCs; And through desorption high-concentration waste gas out, then flowing through with nitrogen is carried into condensing tower 50 by a desorption gas pipeline 44 and carries out condensation, and condensed fluid is reclaimed by an accumulator tank 52, and in addition, condensed gas is then discharged from gas vent 53.
Yet, in the existing fluidized floating bed adsorption system, spherical activated carbon carries out the desorption and regeneration reaction in this desorption column, but in this desorption and regeneration process IPA and Acetone can be under 250 ℃ of desorption temperatures desorption (remaining quantity＜1%) almost completely, but contain the activated carbon of IPA when the heating focus surpasses 250 ℃, meeting pyrolysis incondensable gas Propene, its conversion ratio respectively can be up to more than 90% when hot(test)-spot temperature surpasses 350 ℃.But because this imflammable gas and active height that is difficult for condensing as utmost point low boiling of Propene, especially easilier under the hot conditions that the reducing metal such as iron, cobalt, nickel catalyst exists carry out carburizing reagent containing, if in spherical activated carbon, carry out carburizing reagent, will generate non-type carbon, will block thus the micropore hole in the spherical activated carbon, accelerate deteriorated (the reducing specific area and micro pore volume etc.) of spherical activated carbon, reduction of service life.
Therefore, if contain simultaneously among the VOCs of fluidized floating bed processing IPA or Acetone or polymer (for example: monoethanol ammonia or styrene or cyclohexanone ... etc.) or the words of higher boiling VOCs (such as dimethylformamide or monoethanol ammonia or DOP... etc.), the spherical activated carbon of its use is after desorption and regeneration reaction repeatedly, because the high temperature hotspot pyrolysis goes out Propene, polymer polymerizing is residual or higher boiling VOCs is residual and produce that carbonization generates non-type carbon and problem that can't desorption and regeneration, cause the obstruction in spherical activated carbon micropore hole, and then shorten service life of this spherical activated carbon, simultaneously also have influence on fluidized floating bed purification efficiency, must carry out activated carbon activation operation for this reason.
Yet; general known activation equipment (for example: horizontal rotary stove activation unit); because take up space and can't guarantee to activate uniformity and oxygen-free environment is avoided oxidation reaction; and cause the per kilogram price for can't effective activation regeneration problem on market than (asphaltic base) spherical activated carbon of the high 15-50 of general coal-based column activated carbon times price, cause fluidized floating bed application popularization decline.
