FRP tail gas absorber

Introduction:
FRP tail gas absorption (also known as FRP waste gas purification towers or acid mist spray towers) are among the most widely used equipment in the field of industrial waste gas treatment. This equipment uses glass fiber as reinforcing materials and corrosion-resistant resin as the matrix, manufactured through mechanical winding or hand lay-up processes.
This equipment is mainly used to treat inorganic waste gases (such as sulfuric acid mist, hydrochloric acid mist, nitrogen oxides, etc.) and some organic waste gases generated during industrial production. Its core working principle is to utilize the waste gas and absorption liquid (usually water or a chemically neutralizing liquid) to achieve sufficient gas-liquid contact within the tower. Through physical absorption or chemical reaction, harmful substances in the waste gas are trapped within the tower, thereby achieving the purpose of purifying the gas and protecting the environment.
Core Features:
- Excellent Corrosion Resistance:
The main body of the tower is made of vinyl ester resin and alkali-free untwisted glass fiber composite, with an overall structure resistant to acids and alkalis and corrosion. For highly corrosive environments such as those with strong acids and alkalis, specialized corrosion-resistant resins can be used to ensure long-term stable operation of the equipment in harsh conditions, extending its service life far beyond that of equipment made of ordinary metal or PP materials.
2. Modular Structure Design:
The tower body adopts a segmented design, facilitating transportation and on-site installation. Internal components such as the spray layer, packing layer, and demister layer are independent units, not only simplifying installation but also providing significant flexibility for subsequent maintenance and component replacement, reducing long-term operating costs.

- High Purification Efficiency:
The tower typically features double or multiple layers of packing material with a large specific surface area, ensuring ample gas-liquid contact. Combined with spiral or solid cone non-clogging nozzles, the spray liquid provides uniform coverage without dead zones. Different liquid-to-gas ratios and absorbent formulations are used for different waste gas characteristics, ensuring a stable purification efficiency of over 90%, and even reaching 95%.
- Low Resistance and Low Energy Consumption
Through precise fluid dynamics calculations to optimize the internal structure, the system minimizes pressure drop and reduces fan load while ensuring efficient contact, thereby lowering the overall system's power consumption.
- High Physical Strength
The fiberglass material is not only lightweight and high-strength, but its tensile strength and impact resistance are also superior to traditional plastics. The outer surface of the tower is covered with an anti-aging gel coat layer containing UV absorbers, preventing yellowing, cracking, or powdering even when exposed to outdoor conditions for extended periods.
- Customized Configuration
Automatic dosing systems, automatic pH monitoring systems, and PLC control cabinets can be selected according to the customer's site conditions to achieve fully automated operation, real-time monitoring of operating status, and ensure optimal treatment results.

Application:
Chemical Industry: Treatment of process waste gases such as hydrogen chloride, sulfur dioxide, and ammonia generated from various chemical plant reactors and distillation tanks.
Metallurgical Industry: Purification of sulfur-containing fumes and fluoride gases generated during smelting processes.
Electronics and Semiconductors: Treats acidic gases and organic waste gases generated during etching and cleaning processes.
Wastewater Treatment Plants: Treats odorous gases such as hydrogen sulfide and ammonia emitted from wastewater treatment plants, equalization tanks, and other areas.
