The Snowflake plastic ring is a type of irregular column packing. Characteristics: large porosity, excellent heat resistance and chemical corrosion resistance, good pressure drop, high flood temperature, full contact of steam with liquid, low mass transfer rate and high efficiency.It is used at various average temperatures of 60-150 degrees Celsius. Widely used in thechemical industry, including the production of chlorine and bromine, can be used in absorption, desorption, extraction, dust collection and other devices. It is also often usedfor environmental purposessuch as purification (absorption of acidic (HCL, S02, H2S) gases, VOC removal, wastewater treatment, flue gas treatment).Advantages: when using different ambient temperature within 60-150 degrees Celsius, widely used in petroleum, chemical industry, for alkalis, gases, environmental protection,etc.
