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, as well as convenient maintenance and management. They are the new type of purification equipment for electroplating, pickling waste gas treatment in various industries such as chemical, mechanical, electronic, metallurgical, and instrument industries at home and abroad.
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, collecting a large amount of data. After analysis and organization, the average gas purification rate exceeded 95%, with sulfuric acid mist reaching 90%-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 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 recirculating pump system of the conventional purification tower.
(2) A new filter material, a circular 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 Baur ring filter material in domestic applications.
3. The fiberglass tower body is reliable in quality and performs well.
Based on the working environment of each component of the purification tower, high alkali resistance and high structural strength resins were selected. The exterior is coated with a waterproof, aging-resistant resin. To enhance the tower's strength, several longitudinal reinforcing plates were used on the outer shell, and a combined structure of cylindrical double-tube sections and segmented plates was 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, in addition to the pressure from the tower body itself and the liquid pressure, it also needs to withstand wind pressure during operation (total pressure of the fan at 200-250H2O). Therefore, after careful consideration and elimination of the strength reduction coefficient under strong corrosion and the dispersion performance of the hand-laid-up molding process, our company has designed the entire glass fiber reinforced plastic components to withstand particularly harsh working conditions, ensuring sufficient reserve strength.
