Description
Technical field
When the utility model relates to a kind of solvent strength when fluidized floating bed discharge end and is lower than discharge standard, then make adsorption material in the fluidized floating bed absorption program that circulates, and suspend the energy saver of the fluidized floating bed system for solvent purification that carries out the desorption program.
Background technology
Utilize the adsorption material of high porosity, high-specific surface area, be to remove volatile organic solvent (Volatile Organic Compounds, adsorption method for purifying technology VOCs), the general adsorption systems of using fixed bed by suction-operated more; 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 regneration of adsorbent material after saturated, only when the VOCs that meets high response handles, 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 take place; So,, the fluidised system for solvent purification of a kind of adsorption material and develop in order to improve the shortcoming of ADSORPTION IN A FIXED BED system.
As shown in Figure 1, be the fluidized floating bed system for solvent purification of a kind of known adsorption material, it makes waste gas send into fluidized floating bed 10 bottom with exhaust gas fan 13, and after off-gas flows disperses by air-flow dispersion plate 12, with by on the adsorption material 30 that falls contact, can become Purge gas and from tower top discharge; Wherein, fluidized floating bed 10 inside is separated into several layers with porous plate 11, adsorption material 30 is fallen by fluidized floating bed 10 tops, and above porous plate 11, form unsteady layer, and fall along porous plate 11 peristome in layer, when adsorption material 30 contacts with the waste gas that contains VOCs, the VOCs in the waste gas is adsorbed in the hole of adsorption material 30, waste gas promptly becomes the Purge gas discharging.
Moreover, drop down onto the storage tank 14 of fluidized floating bed 10 bottoms when adsorption material 30 after, be to carry source of the gas 22 by first of adsorption material adsorption desorption conveying device 20, send air or nitrogen formation propelling movement power with the first source of the gas pipe 232 and the second source of the gas pipe 272, through absorption discharge nozzle 21, carry for first time transporter 23, first to carry on the transhipment pipe 231, first to carry adapter 24 and desorption feed pipe 25 to deliver to the top of desorption column 40, carry out the work of desorption and regeneration; 30 of adsorption material behind the desorption and regeneration with desorption discharge nozzle 26, carry transporter 27, second to carry second time to carry adapter 28 and absorption feed pipe 29 to send fluidized floating bed 10 top back on the transhipment pipe 271, second.
Then, adsorption material 30 to be regenerated be in desorption column 40 slowly toward current downflow, and via 42 heating of desorption thermal source, be blown into nitrogen by the desorption source of the gas 43 of desorption column 40 belows again and contact, the VOCs desorption in the adsorption material 30 with adsorption material 30; Adsorption material 30 after adding thermal desorption after the cooling of desorption column 40 bottoms, is sent fluidized floating bed 10 upper ends back to by aforesaid course of conveying again, absorbs VOCs once again; And the high-concentration waste gas that desorption comes out, then carry the desorption nitrogen efferent duct 44 of flowing through and be carried into condenser 46 condensations with desorption nitrogen, condensed VOCs liquid is reclaimed by accumulator tank 47, and the clean nitrogen of condensed desorption is by desorption nitrogen input pipe 45 circulation input desorption column 40; In addition, the high-concentration waste gas that desorption comes out also can be purified by incinerator burning, but because of the purification behind the desorption (condensation or incineration) program, non-ly be the patent target of this case, therefore detailed description no longer.
Yet, because the fluidized floating bed system for solvent purification of aforesaid known adsorption material, because of after it allows adsorption material 30 drop down onto bottom sump by fluidized floating bed 10 tops, deliver to the top of desorption column 40 immediately by adsorption material adsorption desorption conveying device 20, carry out the work of desorption and regeneration, send fluidized floating bed 10 tops again back to, and cause adsorption material 30 circulations to be adsorbed and the desorption program; So, if only contain the low concentration solvent in the waste gas, adsorption material 30 is dropped down onto the single absorption program of bottom sump by fluidized floating bed 10 tops, only can be adsorbed onto a spot of solvent, adsorption material 30 is not adsorbed as yet saturatedly just must carry out that follow-up taking off told and the condensation reclaimer, cause the spent energy of running and handled solvent exhaust gas concentration just irrelevant, and can't be energy-conservation relatively when handling low concentration solvent waste gas.
