Description
Technical field
Benzene, toluene, diformazan are applied to the present invention relates to desorption catalyzing burning all-in-one technical field, more particularly to one kind
The desorption catalyzing burning all-in-one of the VOCs treatments such as benzene, alkane.
Background technology
Absorption is that gas is attached to the mass transfer process that solid gets on.Gas（Adsorbate）Into solid（Adsorbent）'s
In hole but and it is introduced into its lattice.Adsorption process is probably physical process, it is also possible to chemical process.
Physical absorption is mainly Van der Waals force and worked, typically no selectivity, does not have electronics to turn in adsorption process
Move, generation and destruction without chemical bond.Chemisorbed is actually a kind of chemical reaction, with selectivity, in chemisorbed
During, gas and the surface of solids are chemically reacted.The adsorbent most generally used be activated carbon, molecular sieve, silica gel and
Activated alumina.Surface area greatly, can the effective pollutant such as adsorbing hydrocarbon after treatment for these adsorbents.Its shortcoming
It is to have preference suction-operated to water.All adsorbents can change at a high temperature of certain.At these tem-peratures,
Its adsorption capacity is very weak, and pollutant can be freed, so that the activity of adsorbent is regenerated, this process turns into de-
It is attached.
In order to be operated continuously, two or more adsorbent beds are generally provided.One or several adsorbent beds are in absorption, separately
One or several adsorbent beds are then regenerated.In adsorption process, the pollutant being collected is trapped in adsorbent bed, as long as absorption
Bed has enough capacity, and pollutant would not be discharged.But when the pollutant concentration in adsorbent bed reaches saturation, pollution
Thing just starts to discharge, and this phenomenon is referred to as penetrating, and reaches that the adsorbent bed of saturation needs to be regenerated, general to use what is heated
Gas is desorbed to adsorbent bed, on the one hand makes adsorbent bed again active, is on the one hand that pollutant is freed progress
Reclaim or resolution process, existing adsorption-desorption-catalytic combustion process can be obtained by the analysis of above two technique
The characteristics of stating two processing engineerings：Absorbing process：It is adapted to low concentration situation, it is desirable to provide energy carries out desorption and regeneration, is desorbed out
The high density pollution thing come needs to be reprocessed.Burning process：It is adapted to high concentration situation, suitable design technology can be only
Require supplementation with and burning maintained under a small amount of energy scenario, and can produce affluence energy, can thorough decomposing pollutant, catalysis fires
The operating cost of burning is lower.It is combined with reference to above two process characteristic, is adsorbed-taken off and pay-catalytic combustion process, can
Two kinds of techniques are effectively applied to different organic pollutions to maximize favourable factors and minimize unfavourable ones and handle occasion, especially in Wind Volume, low concentration
VOC exhaust-gas treatments in terms of, be at present have the best price/performance ratio handling process mode.
But now universal desorption system is to be heated up with hot blast by adsorption-desorption case, heat temperature raising time long heat
Loss is big, and early stage heating up process organic exhaust gas concentration is low, catalytic combustion system long operational time, early stage desorption temperature-rise period
Power consumption is high.
