High-Gravity Gas Absorption Unit

Interception-Type Wet Desulfurization Equipment

Our desulfurization technology utilizes a high-gravity field to achieve excellent purification results. This field generates strong mass and heat transfer capabilities. Through high-speed rotation, the desulfurizer liquid is dispersed into minuscule films, filaments, and droplets as it passes through the interception layer of the wet desulfurization equipment.

This process, facilitated by the high-gravity field, creates a large specific surface area and a rapidly updated phase interface, ensuring full gas-liquid contact. The capture of sulfur-containing gases like H2S and SO2 is highly selective. This selectivity is due to the collision effect from mechanical rotation, the liquid film's capture effect, and the filtering action of the droplets themselves on low-solubility gases.

Simultaneously, the rotating cut-off ring applies a high shear stress to the liquid, splitting it into incredibly tiny droplets and thin films. The continuous change in direction of the gas and liquid channels significantly extends contact time, providing a superior surface for the absorption of easily dissolved gases.

In the event that impurity gases like H2S and SO2 pass through the interception channel, the large gas-liquid contact area and rapidly updated interface provide a quick reaction site for desulfurization, defluorination, and other reactions.

This technology allows for the efficient removal of impurity gases and is theoretically applicable with wet desulfurization equipment to achieve efficient desulfurization, defluorination, and the removal of various other acidic gases.

Technical Parameters

Advantages of Interception Wet Desulfurization Technology
1. High Mass Transfer Efficiency: The baffle-enhanced structure repeatedly redirects gas and gas-liquid flow, prolonging contact time and significantly improving the reaction efficiency of H₂S with absorbents.
2. Energy & Cost Savings: The baffle-optimized flow paths reduce pressure drop by 20-40% compared to traditional packed towers, which lowers blower and pump energy consumption. The high mass transfer efficiency also minimizes absorbent usage, reducing operational costs.
3. Superior Dust Removal: This technology employs a unique method to effectively capture both hydrophilic and non-hydrophilic dust particles. It also effectively prevents sedimentation and blockage, even when processing dust-laden gas.
4. Compact & Modular Design: The equipment's excellent improvement of mass and heat transfer processes results in a small volume, saving land and allowing for easy, skid-mounted installation. The system occupies only 1/5 to 1/10 the footprint of conventional desulfurization towers and is scalable via parallel or series configurations.
5. Enhanced Selectivity & Reduced Alkali Use: In the high-gravity machine, the very short residence time of gas and liquid, combined with the low solubility of CO₂ in water, limits the production of secondary salts. This increases desulfurization selectivity and reduces alkali consumption.
6. Clog-Resistant & Easy Maintenance: A packing-free design eliminates the common clogging issues found in traditional distillation columns, simplifying cleaning and maintenance with minimal downtime.
7. Flexible Desulfurizer Options: The system can be used with a variety of desulfurizers, including alkali and composite types.
