The utility model discloses a concrete theory of operation: at the adsorption end, organic waste gas with low concentration and large air volume enters the case 1 from the waste gas air inlet 5 and passes through the clockwise rotating zeolite revolving drum 2 to adsorb VOCs on the zeolite molecular sieve square block 14, and clean air after filtration is discharged from the adsorption filter air outlet 7. At the desorption end, after the waste gas enters the machine case 1, most of the waste gas is absorbed by the zeolite molecular sieve square blocks 14 and then is discharged to the absorption filter air outlet 7; a small part of waste gas which is not adsorbed by the zeolite molecular sieve square blocks 14 passes through the high-temperature zeolite molecular sieve square blocks 14 from the cooling zone 10 to enter the second sector zone 12, takes away the heat of the part of zeolite molecular sieve square blocks 14, is conveyed to heating equipment for heating through the desorption air guide pipe 3, is heated into high-temperature desorption gas, is conveyed back to the first sector zone 11 through the desorption air guide pipe 3 to be used as desorption hot air, and discharges VOCs on the zeolite molecular sieve square blocks 14 in the first sector zone 11 through the desorption zone 9 and the waste gas desorption air outlet 6 when the part of heated waste gas passes through the rotating zeolite rotary drum 2; the zeolite molecular sieve blocks 14 passing through the desorption zone 9 are heated by high-temperature desorption hot air, and the temperature is high, so that the zeolite molecular sieve blocks need to enter the cooling zone 10 for cooling to ensure the adsorption capacity of the zeolite molecular sieve blocks. During the cooling, because the temperature of zeolite molecular sieve square block 14 is higher, its adsorption efficiency is relatively poor, so pass the waste gas concentration of zeolite molecular sieve square block 14 still higher from cooling zone 10, as the hot-blast use of desorption after the heating, during the desorption, the VOCs that VOCs and zeolite molecular sieve square block 14 desorption that this part waste gas self carried combine, can improve the waste gas VOCs concentration after the desorption.
