VOC concentration process of the present invention is as follows: the first valve 6, VOC is only opened under conditions of other valves are all closed
Exhaust gas pass through first the first admission line 4 enter Adsorption Concentration device 2, into Adsorption Concentration device 2 after encounter strainer 14, filtering
Under the crown_interception of net 14, the solid particulate matter in VOC exhaust gas is trapped, and is then fallen into accumulation, accumulation in dust accumulation bucket 20 and is arrived
When enough, the 6th valve 22 is opened, Adsorption Concentration device 2 is discharged it and carries out filling or being used as construction material；
The VOC exhaust gas for having filtered solid particulate matter has been crossed after strainer 14 into the first air-spreading disk 15, in the first air-spreading disk 15
Gas distribution effect under, VOC exhaust gas uniformly enters first adsorption layer 16, and the active carbon particle filled in first adsorption layer 16 is to it
Primary adsorption is carried out, 90% or so VOC exhaust gas can be adsorbed, is also contained on a small quantity from the gas that first adsorption layer 16 comes out
VOC exhaust gas, then under the action of the second air-spreading disk 17, VOC exhaust gas is even into the second adsorption layer 18, in the second adsorption layer 18
Under the action of the composite adsorption particle of interior filling, the VOC in exhaust gas is adsorbed completely substantially, and then air after purification is via
Three air-spreading disks 19 enter the second outlet pipe 9 and going out gas branch pipe 12 after coming out, and the 4th valve 11 is kept to close, and open the 5th valve
13, so that air after purification is discharged into atmosphere by the 5th valve 13；
VOC content detects in the gas that going out gas branch pipe 12 is discharged in adsorption process, when detecting that VOC content is greater than
0.16mg/m3When, then the first valve 6 is closed, adsorption process is terminated, starts desorption process, keeps the 5th valve 13 to close at this time,

Amount, and inhale the total gas flow rate entered in gas heater 3 from the first admission line 4 into Adsorption Concentration device 2
The 15%-20% of attached total gas couette, after closing the first valve 6, Adsorption Concentration device 2 enters the after being finally disposed
When gas flow in two outlet pipes 9 is less than aforementioned proportion, the 5th valve 13 is opened, by being arranged in going out gas branch pipe 12
Partial air is pumped into the second outlet pipe 9 by aspiration pump 25, to supply the gas flow for needing to heat；When Adsorption Concentration device
2 finally be disposed after enter the second outlet pipe 9 in gas flow be equal to aforementioned proportion when, then keep the 5th valve 13 close
It closes；The gas flow entered in the second outlet pipe 9 after Adsorption Concentration device 2 is finally disposed is greater than aforementioned proportion
When, the gas flow in the second outlet pipe 9 is entered by the control of flowmeter 24, opens simultaneously the 5th valve 13, discharge is remaining
Gas.
When gas is heated to 130 DEG C or so in gas heater 3, third valve 10 is opened, makes hot-air via second
Admission line 8 enters back into Adsorption Concentration device 2, carries out recoil heating to the VOC adsorbed on adsorbent and is desorbed, after desorption
VOC gas concentration be original 5-10%, then open the second valve 7, make be concentrated VOC gas enter heat-storage type burner 1 into
Row burning, is converted to carbon dioxide and water, then be discharged into atmosphere, to complete the concentration and treatment and purification of VOC.
In desorption process, the hot-air into Adsorption Concentration device 2 contacts third air-spreading disk 19 first, allows gas to enough
Even is distributed in the second adsorption layer 18, is desorbed to the VOC of the second adsorption layer 18 absorption, then has the VOC of high concentration
It after the second air-spreading disk 17 is evenly dispersed, enters back into first adsorption layer 16 and is desorbed, finally obtain the higher VOC gas of concentration
Body；The VOC gas of high concentration eventually pass through the first outlet pipe 5 and burn into heat-storage type burner 1, the heat for generation of burning
Amount can be passed through gas heater 3 and heat to air.
It can be seen that the present invention can be good at adsorbing and being desorbed VOC gas.
It should be noted that the brand of heat-storage type burner 1 used in the present invention is Longxin, model
LX02DRY060；The brand of gas heater 3 is odd connection, model QL-KQ-0318.
Need further exist for explanation, the inlet end of the first air-spreading disk 15, the second air-spreading disk 17 and third air-spreading disk 19
Multiple first qi-emitting holes 23 are equipped with, outlet side is equipped with multiple second qi-emitting holes, passes through the first qi-emitting hole 23 and the second gas distribution
Hole keeps gas and desorption gas to be adsorbed evenly dispersed, and absorption and desorption efficiency can be improved.
The partial size of active carbon particle is 1-3mm, and the partial size of composite adsorption particle is 0.5-1mm, and composite adsorption particle
The preparation method is as follows:
It is mixed after brucite fiber is weighed with pyrophyllite according to the mass ratio of 2:1, is then ground to powder, cross 100 mesh
Sieve, obtains mixed powder, mixed powder is pelletized in granulator, is sintered 2-3h at 400-500 DEG C then to get composite adsorption is arrived
Particle.
Partial size setting of the invention can make adsorption effect keep best, and composite adsorption particle using brucite fiber with
Pyrophyllite is mixed with, and brucite fiber is a kind of fibrous brucite, contains mass crystallization water in structure,
It is sintered at 400-500 DEG C, brucite fiber loses the crystallization water, and numerous active sites, organic matter energy are formed in brucite fiber
It is enough to be adsorbed on active site well；Pyrophillite is easy dissociation between layers and generates some surfaces, and other surfaces
The fracture for being formed as ion and covalent bond, therefore, these surfaces be it is hydrophobic, neutral absorption point can be served as to inhale
Attached organic molecule, therefore, the combination of brucite fiber and pyrophyllite can efficiently adsorb VOC.
In the present invention, composite adsorption particle is arranged close to gas heater 3, high temperature hot gas initially strikes composite adsorption
Grain, this is because under the high temperature conditions, the active site in brucite fiber and pyrophyllite is easier the VOC molecule with absorption
Separation, and the performance of active carbon is easy to be influenced and changed by high temperature, so that its adsorption/desorption effect is influenced, so of the invention
Activated carbon adsorption layer is arranged far from gas heater 3, i.e., after the second adsorption layer 18, temperature is declined hot-air, this
When be passed into activated carbon adsorption layer, can either guarantee good desorption effect, and will not influence the performance of active carbon, can
Enough continue on for the absorption of VOC.
