拉西環(huán)004
陶瓷拉西環(huán)是早開發(fā)的一種散堆填料。形狀簡單，它是高與直徑相等的圓環(huán)。大尺寸的拉西環(huán)（100mm以上）一般采用整砌方式規(guī)則填充，100mm以下的拉西環(huán)多采用亂堆方式裝填。 陶瓷拉西環(huán)具有優(yōu)異的耐酸耐熱性能，能耐除氫氟酸以外的各種無機酸、有機酸及有機溶劑腐蝕，可在各種高溫場合使用，應(yīng)用范圍十分廣泛，可用于化工、冶金、煤氣、環(huán)保等行業(yè)的干燥塔、吸收塔、冷卻塔、洗滌塔、再生塔等
該產(chǎn)品用作填料時，可以增大液體、氣體的接觸面積，提高物質(zhì)的遷移效率，同時增加氣體處理量，提高效益。當其用在水產(chǎn)養(yǎng)殖業(yè)時，其吸附的殺菌液可緩慢在水中釋放；微孔可同時對水起過濾作用，有利于保持水質(zhì)。
ceramic rasching ring is the earliest developed random packing, named after the German chemist Friedrich Raschig. It's small tube cutting, which outside diameter is equal to its height, providing a surface for (re)evaporation of the most volatile part in the refluxing distillate, typically 10 mm in diameter and 12 mm long.
It's used in commercial fractional distillation towers to reduce pressure loss (versus using trays), while maintaining good efficiency and economy. Typically the change in pressure (also called "delta p") is lower than in the case of trays but slightly higher than for structured packing.
With the characters of high mechanical strength, high chemical stability, and excellent heat endurance, Ceramic Raschig Ring can resist high temperature, acid (except HF), alkali, salt and various organic solvents. It's widely applied in various packing towers of desiccation, absorption, cooling, washing, and regeneration in industries of petrochemical, chemical, metallurgy, gas and oxygen generation.
For raschig ring with big size over 100mm, it's usually filled in the column orderly. If its size is less than 100mm, raschig ring is stacked in the column randomly.

Ceramic Saddles are divided into two different types of products according to their properties, KPK-CIS-A is often used in the field of Chemical and Petrochemical industries, and KPK-CIS-B is mainly used in environmental areas such as RTO(Regenerative Thermal Oxidizers) equipment. But both of them are the most frequently used high-performance packing and exhibit advantages for most applications in comparison with other shapes. Their smooth surface imparts a high chemical resistance and provides Ceramic Intalox saddle rings (Ceramic Saddles) with a high level of stability. Due to their simple form, ceramic saddles can be produced at a relatively low cost.

Pall Ringdetail
Ceramic pall ring is a kind of random packing further developed based on Rischig Ring, with two layers of windows opened along its tube wall. The outside diameter is equal to its height. For each layer, there are 3 ligules bending inward the axes of the ring. The open position for windows between the two layers is staggered oppositely.
Generally, the area for open windows occupies 30% of the total area of the tube wall. It helps vapor and liquid flow freely through these windows, making full use of the rings inner surface to improve distribution of vapor-liquid.
With the characters of high mechanical strength, high chemical stability, and excellent heat endurance.
Ceramic Pall Ring can resist high temperature, acid ( except HF ), alkali, salt and various organic solvents. It is widely applied in various packing towers of desiccation, absorption, cooling, washing and regeneration in industries of petrochemical, chemical, metallurgy, gas and oxygen generation.
If ring's size is over 100mm, it is usually filled in column orderly. If its size is less than 90mm, pall ring is stacked in the column randomly.
