It is effectively combined, can solve that adsorbent persistently moves practical problem under air-proof condition and tower is anti-very well using helical feed
Answering device to have, phase border contact area is big, the higher advantage of mass-transfer efficiency, can be realized adsorbent filler constantly with VOCs exhaust gas
The contact of phase border is kept, and is disengaged in time when saturated, continuing purge VOCs exhaust gas technology is asked under the conditions of solving continuous production
Topic；Second, spiral step fin around newel spiral terrace, fix piecewise by the installation of helical stand stepwise, between spiral step fin
Gap walks flowing under for VOCs exhaust gas from above, and adsorbent is entered the spiral step that uniformly booth is multicast to rotation by tower body upper end
It on fin, conveys downwards in tower body inside spin, with the effective contact mass transfer of VOCs exhaust gas, can be led to according to the concentration of VOCs exhaust gas
The revolving speed of adjustment newel and the inlet amount of adsorbent are crossed, realizes the efficient mesh using with continuing purge VOCs exhaust gas of adsorbent
Mark；Third, spiral step fin tower is substantially also helix transporting device, the solid waste of absorption VOCs exhaust gas can be passed through
The discharge of deslagging rotary disc assembly will not block purification device and increase ventilation resistance, reduce ventilation device energy consumption；4th, spiral
Ladder fin has guide functions to VOCs exhaust gas, and VOCs exhaust gas enters from tower body lower part, under the guidance of spiral step fin
Spiral essentially adds VOCs exhaust gas residence time in tower body, thus increase with adsorbent contact mass transfer when
Between, the purification efficiency of adsorbent is improved, also reduces tower body height, the cost of the purification device of saving；5th, VOCs exhaust gas
Through watt grid gap in cloth wind tower component to tower body even distributing wind, and flow velocity is very fast when warp watt grid gap, can be the suction fallen
Attached VOCs exhaust gas solid waste is purged along tower inclined-plane to rotary case, it is not easy to block ventilation hole；6th, always in closed dress
Middle operation is set, the discharge of pollutant is avoided, and can be realized the storage of solid waste centralized collection, for further effective use
The remaining calorific value of absorption VOCs exhaust gas solid waste is realized resource-effective and reduces pollutant emission and has done excellent basis
Work.
