Description
Technical field
The present invention relates to a kind of purification of volatile organic waste gas device and method that is used for the purified treatment volatile organic waste gas, particularly relate to a kind of device of desorbing organic substances on line on temperature-change type fluidized floating bed.
Background technology
Traditionally, utilize the adsorption material of high porosity, high-specific surface area, remove VOC (Volatile Organic Compounds, adsorption method for purifying technology VOCs), the general adsorption systems of using fixed bed more by suction-operated; And the ADSORPTION IN A FIXED BED system criticizes the formula mode of operation with two towers or multitower; Carry out the absorption of waste gas and adsorb the regneration of adsorbent material after saturated; Only when the VOCs that meets high response handles; The chemicals that Chang Yin is adsorbed produces catalyst exothermic oxidation reaction (for example ketone and active carbon adsorption material) in when absorption with adsorption material, causes the not good and a large amount of hot polymerization collection of fixed bed internal heat dissipating, and then generation carbon bed fires or blast problem; So,, a kind of fluidized floating bed adsorption system or zeolite runner collocation branch gasification furnace system and develop in order to improve this shortcoming of ADSORPTION IN A FIXED BED system.
Moreover; The adsorption process of the fluidized bed adsorption system of convention is as shown in Figure 1; Waste gas is sent into the bottom of an adsorption tower 10 from air flow inlet 13 with a blower fan 14; And after off-gas flows mat one air-flow dispersion plate 12 disperses, with by on the spherical adsorption material 30 that falls contact, promptly 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 to be separated into several layers with most porous plates 11, and this spherical adsorption material 30 to be tops via this adsorption tower 10 fall, float layer and above these porous plates 11, form; And fall along these porous plates 11 peristome in layer; When this spherical adsorption material 30 contacts with the waste gas that contains VOCs, the VOCs in the waste gas is adsorbed in the hole of this spherical adsorption material 30, waste gas promptly becomes the Purge gas discharging; Yet, adsorb the storage tank that saturated spherical adsorption material 30 drops down onto these adsorption tower 10 bottoms after, be transported to follow-up desorption program by adsorption material transport 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 adsorbing the storage tank that saturated spherical adsorption material 30 drops down onto these adsorption tower 10 bottoms, carry source of the gas 22, form propelling movement power with its air seen off or nitrogen by one of this adsorption material transport 20; Carry adapter 23, a transfer pipeline 24 and one second to carry adapter 25 to deliver to the top of a desorption column via a discharge nozzle 21, one first, carry out the work of desorption and regeneration; Spherical adsorption material 30 behind the desorption and regeneration then carries adapter 26, the 4th to carry an adapter 27 and a feed pipe 28 to send the top of this adsorption tower 10 back to one the 3rd.
Then; Spherical adsorption material 30 to be regenerated is in the slowly past current downflow of a desorption reaction device of this desorption column; And, be blown into nitrogen by the desorption source of the gas below this desorption column again and contact, the VOCs desorption in this spherical adsorption material 30 with this spherical adsorption material 30 via desorption thermal source heating; Spherical adsorption material 30 behind the desorption is sent this adsorption tower 10 upper ends back to by above-mentioned conveying flow process after this desorption column bottom cooling, absorb VOCs once again; And the high-concentration waste gas that comes out through desorption, then flowing through with nitrogen is carried into a condensing tower by a desorption gas pipeline and carries out condensation, and condensed fluid is reclaimed by an accumulator tank, and in addition, condensed gas is then discharged from a gas vent.
Yet habit has in the fluidized bed adsorption system, in the regenerative process of sorbing material; In this desorption column, carry out desorption reaction, and the desorption thermal source of convention is to heat by the desorption thermal source in this desorption column outside, and this desorption thermal source generally is the electrothermal heating; Conducting heat to the uneven phenomenon of this desorption column Nei Shiyi generation heating-up temperature; And make easily and give birth to the too high situation of this desorption column generation temperature, in addition, the desorption of activated carbon fluidized bed; IPA and Acetone can be under 250 ℃ of desorption temperatures desorption (remaining quantity＜1%) almost completely; But the activated carbon that contains IPA can go out incondensable gas propylene (Propene) by pyrolysis when the heating focus surpasses 250 ℃, its conversion ratio respectively can be up to more than 90% when hot(test)-spot temperature surpassed 350 ℃.And this imflammable gas and active height that is difficult for condensing as utmost point low boiling of propylene (Propene); Especially under the hot conditions that reducing metal catalyst such as containing iron, cobalt, nickel exists, more be prone to carry out carburizing reagent; As in activated carbon, carrying out carburizing reagent, will generate non-type carbon, will block the activated carbon hole thus; Quicken the deterioration of activated carbon, reduction of service life.Therefore among the VOCs that handles of activated carbon fluidized bed if contain the words of IPA simultaneously; The height of its desorption temperature and the uniformity; Except will considering that desorption whether fully; Need consider because the high temperature hotspot pyrolysis goes out the problem of propylene (Propene), this point will limit desorption temperature peak and can't be with the VOCs of higher complete desorption and limit the effect of desorption, then have influence on the usefulness and the activated carbon life-span of activated carbon fluidized bed.
Moreover; The temperature of the desorption column after heating is cooled off difficult; Can't effectively make this absorption alopecia wave maximum utility, be used in that for example PU cloth gluing industry and associated electrical industry or the like are a large amount of to be adopted organic solvents and produce the occasion of a large amount of organic exhaust gas so fail maturation.
For example, in the synthetic skin technology of PU, adopt solvent such as MEK (butanone) and toluene (Toluene) and IPA or the like in a large number, shared ratio accounts for 80% altogether.After coating, must handle through oven dry again, all solvent evaporations; One meter synthetic skin of average manufacturing must use 350 gram solvents, that is discharges 350 gram solvents in atmosphere, causes lot of V OCs pollution; With 90,000,000 meters in full court gulf is that output is the unit basis; Have 30,000 tons organic solvent emission every year, the environmental pollution amount is suitable, and before these toxic emissions if purified treatment in addition fully effectively not; With the environment that badly influences us, will expend the eliminating that the greater amount resource is carried out these pollutions in the future.
Moreover electronics industry adopts zeolite concentration runner collocation incinerator to handle in order effectively to handle the organic exhaust gas that its technology produced, and the method must consume a large amount of the incineration fuel and the energy, is the most economical and the most practical method in the non-removal organic exhaust gas.
