As the analysis of call-catching devices shows, in recent years, special attention has been paid to packed callle-catchers, the working surface of which is a packing element, which can be made in the form of a regularly or irregularly (in bulk) laid layer of packing of various shapes. regular block nozzle, segmental regular nozzle, irregular nozzle, liquid distributor, liquid redistributor, mesh droplet catcher, chevron droplet separator, coalescer filter, cap plate, plate with fixed valves, sieve plate, the main low-profile cap elements are cap elements, swirling plate with centrifuges element of the calligraphy device, affect the efficiency of the droplet collection and the resistance, i.e. on energy costs for transporting gas through the apparatus.
