Under appropriate conditions, the plastic orifice corrugated packing can replace the ordinary packing and part of the plate tower. Because of its large flux, low pressure drop and high specific surface area, it has great advantages in increasing production, expanding application range, reducing energy consumption and improving efficiency. Due to the use of plastic material, its resistance to rice and long life. The outstanding disadvantage is not suitable for the tower with heat transfer requirements. In addition, due to the use of fixed arrangement of the plate to form a fixed packing, the solid particles contained can be discharged through the bottom of the packing corrugated, not easy to accumulate in the packing, therefore, the anti-blocking performance has been improved. When the tower device is designed reasonably, its working elasticity is greater than that of the general filling tower device. In some cases, used to replace certain plate towers and bulk packing towers to increase production capacity or efficiency by 25 or 50 percent, respectively.

At present, the diameter of plastic orifice corrugated packing tower has reached 11m, widely used in the operation of various absorption and desorption devices is in the process of large liquid, high operating pressure. For example, hydrochloric acid, sulfuric acid industry, removal of CO2 and H2S in natural gas, drying of chlorine, preparation of ammonia solution, purification and desorption of various waste gases. The development of domestic plastic orifice corrugated packaging began in the 1980s, has been mass-produced, and has been used in many industrial systems. For example, in the production of urea compound fertilizer, the exhaust gas purification tower with a diameter of 1000, packing height of 1.5m tower, in the fertilizer plant diameter of 1.6m recovery tower, washing the trace ammonia in the gas phase can obtain a higher concentration of ammonia. The 1.6m diameter tower adopts the Laxi ring tower. The pressure drop of the whole column is 1≤2≤1≤3. It is expected that the plastic perforated corrugated packing will be widely used in the near future.
