pan-trough liquid gas distributor

 pan-trough liquid gas distributor is placed at the top of the packed tower liquid distribution device. Its role is to make the liquid in the tower cross-section of uniform distribution, in order to ensure efficient operation.

Common operating pan-trough liquid gas distributor are: shower, impact, pagoda, the porous discharge tube, porous coil, disc and overflow overflow trough. Spray liquid flows down along the filler layer, and can not maintain the original uniform distribution, there is the phenomenon of the flow of the tower wall, affecting the gas-liquid contact, reducing the mass transfer efficiency. Therefore, the filler layer must be fragmented, in placing it between two layers of liquid and then filling the distribution device, the liquid can flow evenly to the lower. (B) sparger aeration fermentation industry generally refers to the fermentation tank to improve air dispersion device. If the mechanical agitation of the fermentation tank ventilation, a hole distributor ring porous tube and pipe.

Common single-hole tube, pipe mouth is central to the fermentation tank bottom, and bottom of the tank with the right to maintain a distance, so that high-speed airflow through the tank at the end of the recoil, so that the air has been well dispersed. Dispersed bubbles rise further broken into small bubbles by blender, to mix with the purpose of fermentation.
