Specific embodiment
A kind of preferred reality of the technology of new raising VOCs treatment efficiency that the invention will now be described in detail with reference to the accompanying drawings
Apply mode.
Show a kind of tool of the technology of new raising VOCs treatment efficiency of the present invention with reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4
Body implementation method：For sake of convenience, the present invention is it is assumed herein that the handled gas containing VOC is following operating mode：
Such as Fig. 1, the gas containing VOC enters into processing equipment (equipment 1) by position 1.Microwave catalysis are mainly by producing
O3, and by O3Removal VOC is reached to aoxidize VOC molecules.Although O3Oxidability it is very strong, but due to VOC and O3Concentration
It is all very low (typically all in 100~300mg/m3, conveniently calculate and press 200mg/m3Meter), and the time of reaction very short (be usually no more than
1 second).In the case of both enough, therefore degree of oxidation (i.e. treatment effeciency) depends on the concentration of two kinds of materials and anti-
The time answered.
Therefore, existing equipment is substantially that the power of increasing equipment increases O3Yield, produced problem is：O3Produce
It is raw excessive, though efficiency can be improved slightly, react still very insufficient, VOC and O3There are a large amount of residues.And for a large amount of
Remaining O3, again without solution.Cause VOC and O3Pollution environment, the single VOC pollutions of hazard ratio are also serious.
As described above, when the gas containing VOC is by 1 access arrangement 1 of position, processing equipment utilizes energy production O3, with VOC
Moieties react, and substantial amounts of O3And VOC molecules are due to time and concentration reason, fail reaction in time, enter with air-flow together
Enter by the access arrangement 2 (active catalytic case 1) of position 2, because the active catalytic carrier in active catalytic case 1 is VOC adsorption-likes
State is in saturation or is substantially saturated state, according to the attribute and index of active catalytic carrier material, in the active catalytic carrier
On, VOC mass-volume concentrations are about 24kg/m3Left and right, and be evenly distributed in active catalytic carrier, i.e., equivalent to VOC in work
Property catalytic carrier on concentration be 24000000mg/m3, it is foregoing VOC gas concentrations 200mg/m3120000 times, and due to manganese
It is the presence of active catalyst, VOC and O3Oxidation reaction speed is also greatly increased.
When containing VOC and O3Gas by active catalytic case 1 when, because VOC concentration is big in active catalytic case 1 and distribution
Uniformly, under active catalyst catalytic action, with the VOC molecule fast reactions in active catalytic carrier, CO is generated2And H2O is simultaneously released
Release, the adsorption space of active catalytic carrier is also released.It is and the VOC minorities passed through are oxidized outward simultaneously but more
The active catalytic carrier being then released adsorption space adsorb after stay in active catalytic carrier.
By after the treatment of active catalytic case 1, most VOC and O3It is processed, the minimal amount of VOC not reacted completely
And O3With air-flow by the access arrangement 3 (active catalytic case 2) of position 3, the VOC of the built-in active catalytic carrier of active catalytic case inhales
Attached state is in slightly adsorbed state, a small amount of O3It is quickly anti-by the VOC molecules in the active catalytic carrier of active catalytic case 2
Should, and a small amount of VOC is then by the VOC adsorption space quick adsorptions in the active catalytic carrier of active catalytic case 2.It is eliminated VOC
And O3Environment protection standard gas be discharged by blower fan.
Electric-control system mode of operation：
Sensor 1, passes the 2 shown position K being respectively provided in the casing of active catalytic case 1 and active catalytic case 2 that grow up to be a useful person, and leads to
Holding wire is crossed to be connected with control system.
VOC adsorbed states such as the built-in active catalytic carrier of active catalytic case 1 are reduced to the 80% of saturation state adsorptive value
When following, control system reduces the operating power of microwave catalysis processing equipment, to reduce O3Supply, maintains system VOC and O3's
Balance；VOC adsorbed states such as the built-in active catalytic carrier of active catalytic case 1 are reduced to less than the 50% of saturation state adsorptive value
When, control system stops the operating power of microwave catalysis processing equipment, to stop O3Supply, maintains active catalytic carrier system
Upper VOC and O3Balance；
VOC adsorbed states such as the built-in active catalytic carrier of active catalytic case 2 are increased to the 30% of saturation state adsorptive value
During the above, control system increases the operating power of microwave catalysis processing equipment, to increase O3Supply, maintains system VOC and O3's
Balance；VOC adsorbed states such as the built-in active catalytic carrier of active catalytic case 2 are increased to more than the 60% of saturation state adsorptive value
When, control system continues on microwave catalysis processing equipment after system treatment VOC end-of-jobs, keeps O3Supply, until
The VOC adsorbed states of active catalytic carrier are just stopped when being reduced to less than the 30% of saturation state adsorptive value, maintain activity
VOC and O in catalytic carrier system3Balance.
The above is only the preferred embodiment of the present invention, it is noted that for the person of ordinary skill of the art,
Without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to guarantor of the invention
Shield scope.
