Fig. 1, Fig. 2, Fig. 3 have described an embodiment of the present utility model.This embodiment is a vertical structure, a swinging absorption body 5 is arranged, swinging absorption body has last fan housing 1 and the following fan housing 9 that compresses thereon respectively in two ends about in the of 5, adsorb body 5 and use sealing strip 2 sealings up and down between the fan housing 1,9, the rotation of swinging absorption body 5 is driven by transmission device 6, by locating wheel 3,8 location,, in the swinging absorption body 5 activated carbon fiber adsorption column 4 is housed by BOGEY WHEEL 7 load-bearing.Swinging absorption body 5 rotates under the driving of absorption body rotation drive machine 6, when if absorption body 5 openings at two ends 16 just in time are positioned at the position of fan housing opening 11 up and down, the gas that contains the organic solvent pollution just enters an end of absorption body from the normal temperature air mouth of an end fan housing, and enter in the swinging absorption body by opening 16, because the two ends of activated carbon fiber adsorption column 4 are all sealed, the air that pollutes can only be by the filter course of activated carbon fiber adsorption column 4, airborne organic solvent is just removed by activated carbon fiber absorption, the air of cleaning enters the normal temperature air accent 11 of other end fan housing from the opening of swinging absorption body 5 other ends, the air of these cleanings through normal temperature air chamber 12 the normal temperature air mouth 10 from this fan housing discharge, deliver to air pipeline, when swinging absorption body 5 openings at two ends 16 when normal temperature air chamber opening 11 rotates to the position of high temperature air chamber opening 14, the high-temperature gas that desorption is used enters high temperature air chamber 13 through high temperature air mouth 15, enter absorption body 5 through high temperature air chamber opening 14 and absorption body 5 openings at two ends 16, by the acf layer on the activated carbon fiber adsorption column 4 time, the organic solvent desorption that the high temperature desorption gas will be adsorbed on rapidly in the activated carbon fiber micropore comes out, at this moment the concentration of the organic solvent in the hot gas will increase 10-20 doubly, this gas that contains high levels of organic solvents enters High Temperature Gas body cavity 13 from the opening 16 of swinging absorption body 5 other ends and the high-temperature gas mouth 14 on the other end fan housing, sends to after high-temperature gas mouth 15 is discharged to the high-temperature gas pipeline and carries out condensation recovery or catalytic combustion.The isolated mutually separate cavities 17 that is divided into some five equilibriums in the swinging absorption body 5, respectively there is an opening 16 at each separate cavities 17 two ends, respectively have normal temperature air chamber opening 11 and High Temperature Gas body cavity opening 14 on the fan housing 1 at swinging absorption body 5 two ends and the fan housing 9, the ratio of the corner angular dimension of opening 11 and opening 14 can change the ratio of activated carbon fiber adsorption time and desorption time, part between opening 11 and the opening 14 (promptly not the part of opening) should be greater than the width of separate cavities 17 on the revolution body 5, is used for preventing being communicated with phenomenon between gas at normal temperature and the high temperature desorption gas.
Fig. 4 has described another embodiment of the present utility model.Present embodiment has adopted horizontal type structure, a horizontal revolving absorption body 5 is arranged, respectively there is a fan housing at the two ends, the left and right sides of horizontal revolving absorption body 5, fan housing is by left and right sides high-temperature gas mouth 25,18 and left and right sides normal temperature air mouth 24,20, and left and right sides High Temperature Gas body cavity 26,19 and normal temperature air chamber, the left and right sides 23,21 compositions.Sealing strip 2, transmission device 6, activated carbon fiber adsorption column 4 are also arranged in this example.Present embodiment is basic identical with heating desorption process and previous embodiment to the adsorption cleaning of airborne organic solvent, difference is that swinging absorption body 5 has adopted prone configuration, swinging absorption body 5 relies on positioning roller 22 and transmission mechanism 6 to locate, this detent mechanism can be made up of a positioning roller 22 and two rotation drive machines 6, these three mechanisms two ends that are distributed in swinging absorption body 5 triangular in shape, the fan housing at swinging absorption body 5 two ends is pressed on the two ends of swinging absorption body 5, both guaranteed sealing to the outside, can prevent that again swinging absorption body 5 from moving vertically, plays the effect of location.
Use activated carbon fiber to replace active carbon paper and the cellular grain active carbon that uses on the at present domestic and international swinging organic solvent separator.Activated carbon fiber content is the highest in the active carbon paper only accounts for 65%, all the other are not 35% for there being the paper pulp of adsorption capacity, therefore compare with pure activated carbon fiber, its adsorption capacity has descended at least 35%, and when using active carbon paper to adsorb still more, gas only is to pass through along the surface of its paper, when flowing, the surface of paper adsorbing, therefore its adsorption effect is poor, and the utility model is to make gas pass acf layer to filter Purge gas, therefore the separative efficiency of organic solvent is wanted high many.The adsorption capacity of grain active carbon and adsorption rate have only part to tens/one of activated carbon fiber, and service life is short.Resistance when reducing activated carbon fibre filtering, the utility model solves by dual mode: first has adopted the activated carbon fiber adsorption column, swinging is adsorbed body be divided into several isolated mutually cavitys, an activated carbon fiber adsorption column is installed in each cavity, the developed area of a plurality of like this activated carbon fiber adsorption columns is sizable, thereby has reduced flowing resistance; Second is to adopt thin filter course, the activated carbon fibre filtering layer is thin more, its flowing resistance is just low more, and during for the air of the organic solvent gas content of handling variable concentrations, just can reach desired decontamination index as long as change the rotating speed of swinging absorption body.Compare with fixed organic solvent adsorbent equipment, owing to adopted helicoid absorber, rotation by the absorption body, can constantly will adsorb the body openings at two ends is switched on or switched off with the opening that is pressed on the fan housing that adsorbs on the body both ends of the surface, saved valve fully, so also just saved the pneumatic and electronic control system corresponding fully, structure has been simplified significantly with valve.
The utility model is to utilize the very excellent adsorption-desorption characteristic of activated carbon fiber to realize the purpose that harmful organic solvent gas (as aromatic series benzene class, aliphatic acids, alcohols, heterocyclic compound and sulfide etc.) is separated from air.Under the normal temperature state, when air passes through the activated carbon fibre filtering layer, the organic solvent that contains in the air is adsorbed by activated carbon fiber rapidly, its adsorption efficiency reaches 98%, like this, just become the very air of cleaning by the air behind the activated carbon fibre filtering layer, through so continuous absorption, after activated carbon fiber has adsorbed certain amount of organic solvent, as long as the steam or the air that will be heated to 120-130 ℃ pass through the activated carbon fibre filtering layer, the organic solvent that is adsorbed in the activated carbon fiber micropore will very rapidly eject, and is taken away by the gas of heat.And, at this moment organic solvent concentration than the concentrated 10-20 of airborne organic solvent concentration doubly, this process is called the desorption process of activated carbon fiber, the gas that contains high levels of organic solvents can adopt the condensation absorption method that it is recycled, also can adopt Production by Catalytic Combustion Process that it is burnt, the heat of its burning can be used to add the air of thermal desorption.Activated carbon fiber when making the hot-air desorption, can 100% ground discharge the organic solvent that adsorbs behind the absorption organic solvent, and its separative efficiency height certainly will will be challenged to the fixed organic solvent separator that accounts for the staple market at present.
