Features of endless garland filler: large void rate, not easy to be blocked, large flux, small resistance and other advantages, and the gap has a large amount of liquid stagnation, so that the tower liquid residence time is longer, increase the gas-liquid contact time.

Plastic garland is a filling material developed by the United States, which has a history of 60 years and has been evaluated as a practical filling material by many friends. Desulfurization tower new PP material polypropylene 47 endless wreath filler by 12 small rings neatly arranged, the shape of a slightly flat sphere, because the filling material can supplement a higher liquid capacity, so the liquid or gas can be well circulated in the interior, can improve the mass transfer efficiency to a degree; Plastic wreath is made of polypropylene material extracted by high temperature processes, in order to make the product can be used in a variety of complex environment is normal, add chlorinated polyvinyl chloride (PVC) and so on many kinds of chemical materials, it also ensures high temperature resistance properties of products, in the condition of the high temperature of one hundred degrees Celsius, also won't easily appear bad situation; The product material is lighter, in the installation process is more convenient, can save a certain amount of time and manpower. It has the characteristics of large voidage, low pressure drop and mass transfer unit height, high flooding point, vapor-liquid contact, small specific gravity, high mass transfer efficiency, and is mainly used in gas washing and purification tower.
