Fiberglass Concentration Tower

This is a highly specialized and efficient exhaust gas treatment device, considered an advanced and superior application of the flushing tower. It not only absorbs pollutants into a liquid, but also achieves pollutant reduction and resource recovery, offering significant economic and environmental advantages.

Core Definition and Working Principle Key Features and Advantages Application Areas

The FRP concentrator, also known as the wet pre-treatment/post-treatment unit of a rotary concentrator system, or simply the tower equipment within an exhaust gas concentration system, serves as a key component in zeolite rotary concentrator or activated carbon concentrator systems.

For clarity, let's use the typical "zeolite rotary concentrator + combustion" system as an example to explain the role of the FRP concentrator:

Why is FRP widely used in concentrator systems?

The reasons are similar to those for flushing towers, but with higher requirements:

Excellent Corrosion Resistance (Core Reason)

FRP provides comprehensive protection against both acidic and alkaline dust in pre-treatment and potentially corrosive combustion products (such as SO₃ forming sulfuric acid) in post-treatment.

Low surface energy, resists adhesion.

The smooth interior resists the adhesion of resin and sticky contaminants, reducing clogging and cleaning issues.

Heat resistance and dimensional stability.

Although it doesn't come into direct contact with the hottest combustion gases, the excellent resin system can withstand temperature fluctuations during pretreatment and processing.

Lightweight, high-strength, and easy to mold.

Large towers and custom shapes can be manufactured to accommodate complex project layouts.

Key Features and Advantages (as part of a system)

Protects core assets

As a pretreatment tower, it effectively protects expensive zeolite rotors or activated carbon, extending their service life and ensuring the long-term, stable operation of the entire concentration system.

Reduces waste gas volume

It works with the rotor to convert high-volume, low-concentration waste gas into low-volume, high-concentration waste gas, significantly reducing the size and energy consumption of subsequent combustion treatment equipment. This achieves the "small furnace achieves big results" effect, resulting in high economic efficiency.

Highly efficient purification

When used as an absorption tower to treat specific pollutants, it can directly and efficiently remove the target substances.

High system integration

FRP towers can be easily integrated with pipelines, pumps, water tanks, and other components to form a complete treatment unit.

Application Areas

FRP concentrators are used in all industries requiring high-volume, low-concentration VOC waste gas treatment and are essential equipment in line with current environmental protection policies:

Coating and spray coating industries: automotive, furniture, home appliance, and mobile phone case spray coating lines.

Printing and packaging industries: flexible packaging printing, tinplate printing, and canning.

Electronics industries: semiconductor cleaning and LCD manufacturing.

Chemical and pharmaceutical industries: fine chemical plants and API production.

Rubber and plastics industries: tire manufacturing and rubber vulcanization.

Summary

The FRP concentrator should not be viewed as a single piece of equipment in isolation, but rather as a key functional module within a highly efficient waste gas concentration and purification system.

Its primary role is as a "guardian"—acting as a pretreatment tower at the front end of the system, protecting the core concentrator (zeolite rotor).

In certain circumstances, it can also serve as a "terminator," directly absorbing and treating specific pollutants after concentration. Its value lies in the fact that the corrosion resistance of FRP ensures the long-term, stable, and efficient operation of the entire high-tech, high-investment concentration system, ultimately helping companies achieve ultra-low VOC emissions and reduced volume at lower operating costs. When selecting a system, its design and selection must be considered from the perspective of the entire system process.
