Plastic ladder rings are mainly used for packing towers and regeneration towers of decarbonization systems in nylon factories, HC absorption towers in pesticide production, CO2 scrubbing towers in chemical fertilizer plants, atmospheric desulfurization towers, carbon dioxide absorption towers, salt brine debromination blowing towers and absorption towers, Steel plant acid mist purification tower and other related equipment and equipment in chemical, fertilizer, environmental protection and other industries. The packed tower adopts plastic stepped ring as the pressure dissolved gas tank, which has low energy consumption and high dissolved gas efficiency. The application examples are as follows: 1. The application of plastic stepped rings in atmospheric packed towers: The ADA desulfurization tower of a chemical fertilizer plant uses φ76mm plastic stepped rings instead of φ80mm ceramic stepped ring packing, which solves the common problem of sulfur blockage in ceramic stepped ring packing in the past, and prolongs the 2. 76mm plastic polypropylene step ring is used for debromination of brine: the salt factory adopts sulfuric acid method to blow bromine from ground brine. The Dg50 plastic stepped ring packing was used to conduct experiments in a 300mm experimental tower. The experiment proved that the pressure drop of the plastic stepped ring packing was only about 30 percent of that of the ceramic stepped ring packing. 6.5mm high plastic stepped ring packing layer is used. Equivalent to the packaging layer of a 10-meter porcelain rod-shaped ring. According to the preliminary design and calculation of the bromine blowing device with an annual output of 500t, trapezoidal sealing ring packing is adopted. 3. Pickling tail gas absorption tower: The plastic packing of pickling tail gas absorption tower is resistant to acid waste gas corrosion, has high absorption efficiency, reduces pressure, reduces energy consumption, and adopts low-pressure plastic fan to resist acid waste gas corrosion. The No. 10 Design Institute of the Fourth Department of Engines has designed the shaping device of the SPF acid gas treatment device. Install Dg38 plastic ladder ring 2M in the absorption tower, and absorb acid waste gas such as HCI, H2SO4, HF, etc. with 10 percent NaOH solution. The absorption rate is as high as 90 percent , and the pressure drop is only 27mmhg. Using 10 percent NaOH solution and ammonia water as raw materials, the adsorption efficiency of HNO3 tail gas can reach 7080 percent .
