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 three simulated production tests on representative models of purification towers with three specifications: DGS-5, DGS-7.5, and DGS-20. A substantial amount of data was collected, which, after analysis and organization, resulted in an average purification rate of over 95% for the gases, and 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 glass fiber reinforced plastic purification tower has been improved, and the following measures have been taken:

(1) Eliminated the circulating pump system of a typical purification tower.

(2) A new filter material, a round ring with a high specific surface area, high perforation rate, uniform holes, regular arrangement, and minimal groove retention phenomenon, has been adopted to replace the commonly used Baur ring filter material in China.

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

Based on the working environments of various components in the purification tower, resins with excellent alkaline resistance and high structural strength were selected. The exterior is coated with a waterproof, anti-aging胶衣树脂. To enhance the tower's strength, several longitudinal reinforcing disks were used on the 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 a long time, it must withstand not only the pressure from the tower itself and the liquid pressure but also wind pressure during operation (total pressure of the fan at 200-250H2O). Therefore, all glass fiber reinforced plastic components must have good corrosion resistance and maintain high tensile and compressive strength. After thoroughly considering and eliminating the strength reduction coefficient under severe corrosion and the dispersion performance factors of the hand lay-up process, our company has designed the entire glass fiber component structure to withstand especially harsh working conditions, ensuring ample reserve strength.
