Glass fiber reinforced plastic absorption towers, compared to general absorption towers at home and abroad, boast 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-generation purification equipment for electroplating, acid pickling waste gas treatment in industries such as chemical engineering, machinery, electronics, metallurgy, and instruments both domestically and internationally.
Product Features:
1. Reliable purification efficiency
During the trial production process, the company conducted three rounds of simulation production tests on the representative DGS-5, DGS-7.5, and DGS-20 models of purification towers in the series, in order to improve product performance. A large amount of data was collected, analyzed, and organized, resulting in an average purification rate of over 95% for the gases and 90%-95% for sulfuric acid mist.
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 section of the tower by a fan, forming a pressure chamber, which is then evenly distributed to each bubble tube by the pressurized 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 contact between the gas and liquid. Afterward, the liquid is removed by the desiccant 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 taken:
(1) Eliminated the circulating pump system of the conventional purification tower.
(2) A new filter material, a round ring with a large specific surface area, high perforation rate, uniform hole distribution, regular arrangement, and minimal indentation phenomenon, has replaced the commonly used Pall ring filter material in China.
3. The glass fiber tower body is reliable in quality and performs well.
Based on the working environments of various components within the purification tower, high alkali resistance and structural strength resins were selected, with the exterior using waterproof and aging-resistant gel-coated resins. To enhance the tower's strength, several longitudinal reinforcing plates were used 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 itself 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 possess excellent corrosion resistance and maintain high tensile and compressive strength. After careful consideration and elimination of strength reduction coefficients under severe corrosion and the dispersion characteristics of hand-laid-up molding processes, our company has developed glass fiber components specifically tailored to the tower's structural and environmental characteristics, ensuring sufficient reserve strength in particularly harsh working conditions.
