The fiberglass absorption tower boasts high purification efficiency, compact structure, attractive appearance, small land occupation, excellent corrosion and aging resistance, high strength, lightweight, easy transportation and installation, and convenient maintenance. It is a new type of purification equipment for electroplating, acid pickling exhaust gas treatment in various industries such as chemical, machinery, electronics, metallurgy, and instrumentation at home and abroad.
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 the series, covering three 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 and sulfuric acid mist levels ranging from 90% to 95%.
2. Reasonable structural design
The DGS series acid mist purification towers use sodium hydroxide solution as the absorption and neutralizing liquid. Acid mist waste gas is forced into the middle inner cylinder of the purification tower by a fan, forming a pressure chamber, which is then evenly distributed to each bubble tube by the pressure intensifier. The waste gas enters the absorption and neutralizing 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 recontact between the gas and liquid. After dehydration by the dehydration 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 fiberglass tower body is of reliable quality and excellent performance.
Based on the working environment of each component 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 surface. 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 segmented pieces 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 (total pressure of the fan at 200-250H2O). Therefore, all glass fiber reinforced plastic components must have excellent corrosion resistance and maintain high tensile and compressive strength. After thorough consideration and elimination of the strength reduction coefficient under severe corrosion and the dispersion characteristics of the hand-laid-up molding process, our company has designed the entire glass fiber reinforced plastic components and ensured an ample reserve of strength, tailored to the specific structural and environmental characteristics of the tower.
