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, corrosion and aging resistance, high strength, lightweight, easy transportation and installation, and convenient maintenance. They are the new type of purification equipment for electroplating, acid pickling exhaust 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 simulated production tests on the representative DGS-5, DGS-7.5, and DGS-20 models of the series, in three different specifications of purification towers. A substantial amount of data was collected, analyzed, and organized, resulting in an average purification rate of over 95% for the 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 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 desiccation by the desiccant fan, the gas 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 typical 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 China.

3. The glass fiber tower body is reliable in quality and performs well.

Based on the working environments of various components in the purification tower, high alkali resistance and high structural strength resins were selected, with a waterproof and aging-resistant胶衣树脂 used for the exterior. To enhance the tower's strength, several longitudinal reinforcing disks were applied to the outer shell, and a combined structure of cylindrical double-tube sections and segmented sheets was adopted according to the size of various models. Since the purification tower operates in an acidic and alkaline corrosive gas environment for extended periods, in addition to the pressure from the tower itself and the liquid pressure, it must also withstand wind pressure during operation (total pressure of the fan at 200-250H2O). Therefore, after thoroughly considering and eliminating 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 (GFRP) components to withstand particularly harsh working conditions, ensuring ample reserve strength.
