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 types of purification equipment for electroplating, pickling, and 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 three simulations of the representative models DGS-5, DGS-7.5, and DGS-20 in the series, testing three specifications of purification towers. A substantial amount of data was collected, analyzed, and compiled, revealing an average purification rate of the gas over 95%, with sulfuric acid mist reaching 90%-95%.
2. Reasonable structural design
The DGS series acid mist purification tower utilizes a sodium hydroxide solution as the absorbent and neutralizing liquid. Acid mist waste gas is forced into the middle section inner cylinder of the purification tower by a fan, forming a pressure chamber. It is then evenly distributed to each bubbling tube from the pressure chamber. The waste gas enters the absorption and neutralizing liquid in the storage tank through the bubbling tubes, causing bubbles to form. The bubbles pass through a filter material ring layer, allowing for further contact between the gas and liquid. After dehydration by the dehumidifying fan, the gas is released into the atmosphere. Based on the above design principles, improvements have been made to the general fiberglass purification tower structure, including the following measures:
(1) Eliminated the circulating pump system of the general purification tower.
(2) A new filter material, a circular patterned annulus 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 fiberglass tower body is of reliable quality and excellent performance.
Based on the working environment of various components 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 exterior. To enhance the tower's strength, several longitudinal reinforcing plates 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, in addition to the pressure from the tower 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 have excellent corrosion resistance while maintaining high tensile and compressive strength. This is achieved by ensuring a sufficient reserve strength under particularly harsh working conditions.
