And it places the absorbent module that drawer is constituted and takes out, and be placed in the desorption column of adsorbent regeneration unit；Then, adsorbent reactivation
Unit brings into operation, and burner work makes hot gas enter desorption column, Hot swapping goes out the VOCs of activated carbon adsorption, VOCs gas
Body generates CO in the reaction of the combustion chamber of burner2And water；After processing, gas is up to standard, and portion gas passes through adsorbent reactivation list
Enter active carbon after the cold air mixing that chimney (the i.e. exhaust emissions equipment) discharge of member, part hot gas and fresh-air fan are blown into
Desorption column.It is whole after VOCs concentration is lower than discharge standard in the gas that active carbon desorption column hot recycling comes out after several hours
A system regeneration is completed.After to be adsorbed dose is cooled to room temperature, adsorbent and placement drawer that regeneration is completed integrally are taken out, put back to
Absorbing unit.
The concentration of VOCs is 50~150mg/m in exhaust gas before handling in this example3, after activated carbon adsorption, exhaust gas is obtained only
Change, concentration≤60mg/m of VOCs in tail gas3, purified exhaust gas qualified discharge.When the adsorption saturation of activated carbon adsorption unit
Between be 1 month to half a year etc., to guarantee that the active carbon of each absorbing unit can regenerate in time, the active carbon of each absorbing unit
It should be according to pollution sources production regular regeneration.To improve reproducing adsorbent regeneration unit operational efficiency and further decreasing regeneration
Expense, the absorbent modules of different enterprises can simultaneously regenerative adsorption for a period of time after, take out active carbon and regenerated, regeneration temperature 80
DEG C~120 DEG C, regenerate the VOCs concentration≤6000mg/m come3, VOCs is reacted in combustion chamber generates CO2And water, gas after burning
Middle VOCs≤60mg/m3, treated gas qualified discharge.Device needs to start combustion in system starts and stop transport about half an hour
Burning machine, burns natural gas to heat gas containing VOCs to catalyst light-off temperature, and the heat that when normal operation reacts generation can be tieed up
It holds reaction to carry out, only blower power consumption.
The invention is not limited to specific embodiments above-mentioned.The present invention, which expands to, any in the present specification to be disclosed
New feature or any new combination, and disclose any new method or process the step of or any new combination.
