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, excellent corrosion and aging resistance, high strength, light weight, easy transportation and installation, and convenient maintenance. They are the new type of purification equipment for electroplating, pickling waste gas treatment in the chemical, mechanical, electronic, metallurgical, and instrument industries both domestically and internationally.
Product Features:
1. Reliable purification efficiency
During the trial production process, the company conducted simulated production tests on three representative models of purification towers in the series: the DGS-5, DGS-7.5, and DGS-20 models in three different specifications. A substantial amount of data was collected, analyzed, and organized, resulting in an average purification rate of over 95% for the gases, with sulfuric acid mist ranging from 90% to 95%.
2. Reasonable structural design
The DGS series acid mist purification towers use sodium hydroxide solution as the absorption and neutralization liquid. Acid mist waste gas is forced into the middle inner cylinder of the purification tower by a fan, forming a pressure chamber, and then evenly distributed to each bubble tube by the pressure intensifier chamber. The waste gas enters the absorption and neutralization liquid in the storage tank through the bubble tubes, causing bubbles to form. The bubbles pass through the filter material ring layer, allowing for a thorough re-contact between the gas and liquid. After the gas is dehydrated by the dehydrating fan, it is then 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 taken:
(1) Eliminated the circulating pump system of a typical purification tower.
(2) A new filter material, a round ring with a large specific surface area, high perforation rate, uniform holes, regular arrangement, and minimal groove retention, has been adopted to replace the commonly used Baole ring filter material in China.
3. The fiberglass tower body is reliable in quality and performs well.
Based on the working environments of various components within the purification tower, we have selected resins with excellent alkali resistance and high structural strength, and used waterproof and aging-resistant gel-coated resins for the exterior. To enhance the tower's strength, several longitudinal reinforcing disks are used on the tower's outer shell, and a combined structure of cylindrical double-tube sections and segments is adopted according to the size of various models. As the purification tower operates in an acidic and alkaline corrosive gas environment for a long time, it must withstand not only the pressure from the tower itself and the liquid pressure but also wind pressure during operation (full pressure of the fan at 200-250H2O). Therefore, all glass fiber reinforced plastic (GFRP) components must have good 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 performance factors of the hand-laid-up molding process, our company has designed the entire GFRP components to meet the requirements of especially harsh working conditions, ensuring adequate reserve strength.
