Glass fiber reinforced plastic absorption towers, compared to general absorption towers at home and abroad, feature 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, acid pickling waste gas treatment in industries such as chemicals, machinery, electronics, metallurgy, and instruments at home and abroad.
Product Features:
1. Reliable purification efficiency
During the trial production process, the company conducted simulation production tests on three representative models of purification towers from the series, the DGS-5, DGS-7.5, and DGS-20 models in three different specifications, three times in total. A substantial amount of data was collected, analyzed, and organized, revealing an average purification rate of over 95% for gases, and sulfuric acid mist levels between 90% and 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, improvements have been made to the structure of the general glass fiber reinforced plastic purification tower, including the following measures:
(1) Eliminated the recirculating pump system of the general 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 China.
3. The glass fiber tower body is reliable in quality and has excellent performance.
Based on the working environment of each component of the purification tower, high alkali resistance and high structural strength resins were selected, with a waterproof and aging-resistant gel coat resin used on the surface. To enhance the tower's strength, several longitudinal reinforcing disks were employed on the tower's outer shell, and a combined structure of cylindrical double-tube sections and segments was adopted according to the size of various models. Since 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 liquid pressure but also the wind pressure during operation (full pressure of the fan at 200-250H2O). Therefore, all glass fiber reinforced plastic components must have excellent corrosion resistance and maintain high tensile and compressive strength. After thorough consideration and elimination of the strength reduction coefficient under severe corrosion and the dispersion characteristics of the hand-laid-up molding process, our company has designed the entire glass fiber reinforced plastic components to meet the requirements of particularly harsh working conditions, ensuring ample reserve strength.
