Tongli FRP Venturi scrubber When the gas velocity at the throat of the venturi tube is controlled at 68-70m/s, the liquid-gas ratio is 0.46-0.51/Nm3, and the fluorine concentration in the flue gas is only 0.4-0.5l/Nm3, its defluorination efficiency can reach 90-96%. At the same time, the venturi tube also has a high dust removal efficiency for lime in the flue gas. Some lime is mainly alkali metal oxides such as calcium oxide (CaO). When they enter the liquid phase, they react with the hydrofluoric acid absorption liquid, neutralizing the absorption liquid to make its pH value reach 5. The venturi tube plays a role in defluorination, dust removal and neutralization at the same time.
The FRP Venturi scrubber can handle a variety of gas flow rates from 5000 cubic meters/hour to 50,000 cubic meters/hour, adapting to industrial needs of different sizes. Its flexibility enables it to operate efficiently in both small factories and large industrial facilities, and has a wide range of applications.
The FRP Venturi scrubber adopts high-speed injection and turbulent flow technology, and the dust removal efficiency of particles as small as 1 micron is as high as 99.8%. It is particularly suitable for the capture of fine dust and fine particles, and is widely used in pharmaceutical, chemical and other industries. It can effectively reduce the emission of atmospheric pollutants and meet strict environmental protection standards.
The Venturi scrubber made of high-performance FRP material can operate stably in strong acid and alkali environments with a pH value of 1-14, and its service life can reach more than 15 years. Its corrosion resistance makes it particularly suitable for treating industrial waste gas containing corrosive gases, such as sulfuric acid, hydrochloric acid, etc., effectively reducing the frequency of equipment replacement and maintenance costs.

A fiberglass Venturi scrubber is an efficient gas purification device that utilizes the Venturi effect to remove particulate pollutants and harmful gases from the air. Its basic working principle involves creating a high-speed airflow through a throat, causing particles in the gas to be captured by a liquid due to inertial force.
The material advantages of fiberglass provide excellent corrosion resistance, enabling it to handle strong acidic and alkaline waste gases. It is primarily used in industries such as chemicals, pharmaceuticals, metallurgy, and power generation, which involve extensive gas processing and pollutant emissions.
Its efficient particle capture capability and low operational cost make it an ideal choice for industrial gas purification. Additionally, the lightweight and high-strength characteristics of fiberglass facilitate easy installation and maintenance, making it suitable for various industrial scenarios.
The dust removal efficiency of a fiberglass Venturi scrubber is typically over 99%, with exact values depending on design parameters and operating conditions. Its high dust removal performance is due to the synergy between the high-speed airflow generated by the Venturi effect and the liquid spray system.
By optimizing the design, the scrubber can capture particles with diameters ranging from 1 to 10 microns and even has a significant capture effect on smaller particles, such as those below 0.5 microns.
The efficiency of dust removal is also influenced by the properties and density of the spray liquid. Adjusting these parameters appropriately can further improve efficiency.
The fiberglass Venturi scrubber is lightweight, typically about one-third the weight of traditional metal equipment. Fiberglass is a light yet strong material, composed of glass fibers and resin, with a specific gravity of approximately 1.5 to 2.0, much lower than steel's 7.8.
This lightweight characteristic facilitates easier installation and transportation, reducing the need for lifting equipment and infrastructure. Additionally, the lighter equipment imposes less load on supporting structures during operation, lowering infrastructure investment costs.
Therefore, the lightweight and high-strength features of fiberglass Venturi scrubbers make them an ideal choice for industrial gas treatment applications.
Fiberglass Venturi scrubbers are made from fiberglass (FRP) materials, which have the following characteristics: excellent corrosion resistance, capable of withstanding acids, alkalis, and salts. They also possess high mechanical strength, with tensile strength typically above 1200 MPa.
The material is lightweight and strong, about one-third the weight of traditional metal equipment, facilitating easy installation and transport. Fiberglass also offers excellent aging resistance, with a typical service life exceeding 15 years..
Additionally, fiberglass materials provide good electrical and thermal insulation properties, allowing the equipment to operate stably under various complex conditions and making it widely applicable in numerous industries.
The pressure drop of a fiberglass Venturi scrubber typically ranges from 1000 to 4000 pascals, with exact values depending on the equipment design and operating conditions. Pressure drop refers to the pressure loss incurred as gas passes through the scrubber and is a crucial parameter for evaluating equipment performance.
An appropriate pressure drop ensures sufficient gas-liquid contact and efficient particle capture. By optimizing throat design and the spray system, a fiberglass Venturi scrubber can maintain high purification efficiency.
It keeps the pressure drop within a reasonable range, thereby reducing energy consumption and enhancing operational efficiency.
Fiberglass Venturi scrubbers are designed to operate effectively across a broad range of temperatures, typically from -20℃ to 120℃. The fiberglass material has inherent thermal stability, allowing it to maintain structural integrity and performance under varying thermal conditions.
This capability is particularly beneficial in industries where temperature fluctuations are common, such as power generation and metallurgy. The scrubber's ability to withstand high temperatures ensures that it can handle hot gases without degrading, while its resistance to cold prevents brittleness and cracking.
Moreover, the thermal insulation properties of fiberglass help minimize energy loss, enhancing the overall efficiency of the gas purification process. This makes fiberglass Venturi scrubbers a reliable choice for continuous operation in demanding environments.
A large amount of dust-containing flue gas is generated in industrial production such as furnaces and cement manufacturing. The Venturi scrubber uses high-speed water flow to make the dust fully contact with water. The dust is adsorbed and condensed by water and then discharged with the water flow to achieve the purpose of dust removal.
Most of it comes from the combustion of sulfur-containing fuels. In the Venturi scrubber, the alkaline absorption liquid reacts chemically with the SO2 in the flue gas to convert it into substances such as sulfites, thereby achieving desulfurization.
Common in chemical production and other processes. After the HCl gas is passed into the Venturi scrubber, it reacts with the alkaline solution in the tower to generate salt and water, effectively removing hydrogen chloride.
H2S is produced in petroleum refining, sewage treatment, etc. The absorbent in the Venturi scrubber can react with H2S Reaction, converting it into harmless substances such as sulfide, reducing harm to the environment and human body.
NOₓ is produced by high-temperature combustion. By spraying a reducing agent or absorbent into the Venturi scrubber, NOₓ can undergo a chemical reaction under certain conditions and convert it into harmless gases such as nitrogen, thereby reducing nitrogen oxide emissions.
VOCs emitted by chemical, coating and other industries are absorbed and dissolved by organic solvents or detergents in the Venturi scrubber, or decomposed by chemical reactions, thereby reducing VOCs emissions.
Ammonia is produced in some chemical processes and agricultural production. The acid solution in the Venturi scrubber can neutralize ammonia to generate ammonium salts, thereby removing ammonia and preventing it from polluting the environment.
For example, flue gas containing heavy metals (such as mercury, lead, etc.) produced by the metallurgical industry, the Venturi scrubber can make heavy metal particles contact with the absorption liquid, and through physical adsorption, chemical reaction, etc., the heavy metals are intercepted or converted into precipitation, reducing their content in the flue gas.
