LiandaFiltration liquid collector adopts modular trough\/tube design, which can accurately converge and distribute liquid phase to ensure uniform and stable liquid level in the tower. It is made of 316L stainless steel, which is corrosion-resistant and high-temperature resistant (\u2264250 \u2103). The dead-angle channel supports online backwashing and chemical cleaning, and the pressure drop is \u226410 mbar. It is quick to install and disassemble, with low maintenance cost, and is widely used in distillation, absorption and washing towers.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Liquid collectors are specially designed for the aggregation and redistribution of liquids in packed towers to ensure that residual liquids do not splash and converge evenly.<\/p>

There are two main structures:
Shuttered liquid collector:<\/p>

Shuttered collector is placed below the packing layer, supported by flanges or split structures, and collects the falling liquid in one whole section;<\/p>

Rising tube liquid collector:<\/p>

Shuttered collector is placed below the packing layer, supported by flanges or split structures, and collects the falling liquid in one whole section; Rising tube collector combines with the gas rising pipeline to take care of the gas-liquid uniform distribution and overflow reflux.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Full-section collection
The baffle-type liquid collection tray is used to collect the falling liquid without dead corners, ensuring that there is no residue under the packing and improving the redistribution efficiency.<\/p>

Low resistance design
The overflow trough and the annular trough work together to drain the liquid, and the resistance is almost negligible, which does not affect the uniformity of gas distribution in the tower.<\/p>

Modular installation
Supports the split liquid collector structure, which can be quickly assembled from the manhole and is suitable for large-diameter towers and segmented maintenance.<\/p>

Dual-function gas-liquid compatible
The riser pipe collector integrates a liquid baffle and an opening design, which can take into account the gas rising channel while collecting the reflux, and is suitable for high-performance gas-liquid distribution needs.<\/p>

Korrosions- und Hochtemperaturbest\u00e4ndigkeit
316L stainless steel material, mirror polished or sandblasted surface, meets harsh working conditions such as chemical, petrochemical, and environmental protection.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
