13, which should be arranged on 5 tube body of desorption inlet pipe between catalytic combustion system 12 and recently adsorption box 1, together
When, mend the benefit air-cooler 14 for being also equipped with and being pumped into ambient atmos in benefit cool air hose 13 on cool air hose 13, therefore, catalysis burning dress
It sets after 12 high-temperature gases that are discharged into desorption inlet pipe 5 first mix with the gas at normal temperature in benefit cool air hose 13, enters back into adsorption box 1
In.In addition, being installed in series on being located at the tube body for mending the desorption inlet pipe 5 between cool air hose 13 and catalytic combustion system 12 has master
Valve 16；Therefore, when closing main valve 16, the high-temperature gas in catalytic combustion system 12 cannot pass through desorption inlet pipe 5 into
Enter adsorption box 1, can only all be discharged into exhaust tube 9, at this point, the gas at normal temperature only mended in cool air hose 13 passes through desorption inlet pipe
Therefore 5 can quickly and efficiently cool down to the filter medium in adsorption box 1 into adsorption box 1；Certainly, it mends on cool air hose
Further preferably be in series with air hose valve, therefore, when do not need for cold wind to be discharged into mixed in desorption inlet pipe with high-temperature gas when,
Air hose valve can be closed, secondly, air hose valve also can control into the cold flow in desorption inlet pipe；Separately
Outside, in order to avoid the thermal-flame in catalytic combustion system 12 enters adsorption box 1, between main valve 16 and main exhaust
Being installed in series on the tube body of desorption inlet pipe 5 has fire arrester 17, which is to prevent inflammable gas and flammable liquid steam
The safety device that spreads in the duct of flame.
In conclusion the utility model is not limited to above-mentioned specific embodiment.Those skilled in the art are not departing from this reality
Under the premise of with novel spirit and scope, several change and modification can be done, it is practical new that all these variations should all fall into this
The protection scope of type.
