Glass-fiber reinforced plastic absorption towers are superior to general absorption towers at home and abroad, featuring high purification efficiency, compact structure, attractive appearance, small land occupation, corrosion and aging resistance, high strength, light weight, convenient transportation and installation, as well as easy maintenance and management. They are the new purification equipment for electroplating, pickling waste gas treatment in the chemical, mechanical, electronic, metallurgy, and instrumentation industries, both domestically and internationally.
Product Features:
1. Reliable purification efficiency
During the trial production process, the company conducted three simulated production tests on the representative DGS-5, DGS-7.5, and DGS-20 models of purification towers in the series, in various specifications. A large amount of data was collected, analyzed, and organized, resulting in an average purification rate of over 95% for the gases, with sulfuric acid mist reaching 90%-95%.
2. Reasonable structural design
The DGS series acid mist purification tower uses sodium hydroxide solution as the absorption and neutralizing liquid. Acid mist waste gas is pressed into the middle cylinder of the purification tower by a fan to form a pressure chamber, then evenly distributed to each bubble tube by the pressurized chamber. The waste gas enters the absorption and neutralizing liquid in the storage tank through the bubble tubes, causing bubbling. The bubbles pass through the filter material ring layer, allowing for a thorough gas-liquid contact. Afterward, the gas is dehydrated by the dehydrating fan and released into the atmosphere. Based on the above design principles, the structure of the general glass fiber reinforced plastic purification tower has been improved, and the following measures have been adopted:
(1) Eliminated the circulating pump system of the typical purification tower.
(2) A new filter material, a circular patterned ring with a larger specific surface area, higher perforation rate, uniform holes, regular arrangement, and minimal groove retention, has been adopted to replace the commonly used Baur ring filter material in domestic applications.
3. The glass fiber tower body is of reliable quality and excellent performance.
Based on the working environment of various components in the purification tower, high alkali resistance and structural strength resins were selected, with a waterproof and aging-resistant胶衣树脂 used for the exterior. To enhance the tower's strength, several longitudinal reinforcing plates were applied to the tower shell, and a combined structure of cylindrical double-tube sections and segmented sheets was adopted according to the size of various models. As the purification tower operates in an acidic and alkaline corrosive gas environment for an extended period, it must withstand not only the pressure from the tower body and the solution pressure but also wind pressure during operation (fan total pressure at 200_250H 2 O). Therefore, all glass fiber reinforced plastic (GFRP) components must have excellent corrosion resistance and maintain high tensile and compressive strengths. After careful consideration and elimination of the strength reduction coefficient under severe corrosion and the dispersion characteristics of hand-laid-up molding processes, our company has designed the entire GFRP components to withstand especially harsh working conditions and to maintain a sufficient reserve strength.
