AI Technical Summary
Existing biogas purification and pretreatment technologies suffer from low gas-liquid separation efficiency, short adsorbent lifespan, low absorption efficiency, and a lack of adsorbent recycling systems, leading to resource waste and environmental pollution.
A device comprising a spiral shaft gas-liquid separator, a desulfurization tank, and an absorption tower was designed. The device uses spiral motion to separate liquid impurities from biogas, and uses a specially formulated desulfurization adsorbent and a spray nozzle to increase the gas-liquid contact area, thereby enabling the recycling of the adsorbent.
It improves the purification efficiency of biogas, reduces operating costs, reduces the consumption of absorbent and waste, and achieves efficient resource utilization and environmentally friendly treatment.
