Glass fiber 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, as well as convenient maintenance and management. They are the new-generation 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 three simulation production tests on the representative DGS-5, DGS-7.5, and DGS-20 models of the series, each in three different specifications, to assess product performance. A substantial amount of data was collected, analyzed, and organized, revealing an average purification rate of over 95% for gases, 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 fiberglass purification tower has been improved, and the following measures have been taken:
(1) Eliminated the circulating pump system of the conventional purification tower.
(2) Utilizes a new filter material, a circular ring with a large specific surface area, high perforation rate, uniform holes, regular arrangement, and minimal channel retention, replacing the commonly used Baur ring filter material in China.
3. The glass fiber tower body is of reliable quality and excellent performance.
Based on the working environment of various components in the purification tower, high alkaline resistance and 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 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 different models. As 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, all glass fiber reinforced plastic (GFRP) components must have good corrosion resistance and maintain high tensile and compressive strengths. After thoroughly considering and eliminating the strength reduction coefficient under severe corrosion and the dispersion characteristics of hand lay-up processes, our company has designed the tower structure and material to ensure adequate strength and ample reserve strength for particularly harsh working conditions.
