Product Description:
A desulfurization tower is a tower type equipment used for desulfurization treatment of industrial waste gas. The most widely used application of desulfurization tower was initially built with granite, which utilizes the principle of water film desulfurization and dust removal, also known as granite water film desulfurization and dust removal device or granite water film desulfurization and dust removal device.
The advantage is that it is easy to maintain and can achieve both dust removal and desulfurization (denitrification) effects by preparing different dust collectors. With the development of fiberglass technology, desulfurization towers are gradually being made of fiberglass. Compared to granite desulfurization towers, fiberglass desulfurization towers have lower costs, easier processing, rust resistance, and lighter weight, making them the development trend of desulfurization towers in the future. After years of improvement, various types of desulfurization towers have been developed, including the Wenqiu Li type, swirl plate type, swirl column type, floating ball type, sieve plate type, and pneumatic emulsion type. The equipment technology is becoming increasingly mature, each with its own advantages and disadvantages. Enterprises can choose different types according to their own needs.

Applications:
1, Definition and Materials
Fiberglass desulfurization tower is an environmentally friendly equipment made of glass fiber reinforced plastic (FRP) as the core material, which is made of resin matrix, glass fiber and auxiliary materials through composite technology. Compared with the traditional granite material, it has the characteristics of light weight (density 1.5-2.0g/cm ³), acid and alkali corrosion resistance, aging resistance, etc., and its manufacturing cost is reduced by 30% -50% 16.
2, Structural composition
Core components
Tower body: Adopting a split structure for easy transportation and installation, it contains spray layer, defogging layer, etc. inside;
Spray device: evenly spray desulfurizer (such as NaOH solution, limestone slurry) through atomizing nozzle;
Packing layer: Increase the gas-liquid contact area and improve reaction efficiency.
Auxiliary system
Mixing device: Ensure thorough mixing of desulfurizer and flue gas;
Discharge outlet: The treated clean flue gas is discharged through the chimney to meet the standard.
3, Working principle
The sulfur-containing flue gas enters from the bottom of the tower and comes into contact with the sprayed alkaline desulfurizer in reverse flow, undergoing a chemical reaction (such as SO ₂+CaCO ∝ → CaSO ∝·ݤ H ₂ O+CO ₂) to neutralize acidic gases. After purification, the flue gas is dehydrated through a defogging layer, resulting in a significant reduction in the concentration of pollutants emitted (with a SO ₂ removal rate of 85% -95% and a dust removal rate of over 98%).
4, Performance advantages
Efficient and environmentally friendly: capable of synchronously processing various harmful gases such as SO ₂, HF, NH ∝, etc., with a Ringman blackness level of less than 1;
Strong economy: low operating resistance, water-saving and energy-saving, low maintenance costs;
Wide applicability: Supports various desulfurizers such as lime and magnesium oxide, suitable for working conditions with sulfur content ranging from 0.5% to 11%;
Long lifespan: Temperature resistance range of -10 ℃~100 ℃, with a service life of over 20 years.
