High gravity interception wet desulfurization equipment absorption tower/desulfurization tower

High gravity interception wet desulfurization equipmentBy utilizing the excellent mass and heat transfer performance of the supergravity field, a good purification effect can be achieved. During the process of passing through the interception layer of the desulfurization equipment, the desulfurizer liquid is dispersed into small liquid films, liquid filaments, and liquid droplets under the action of high gravity due to high-speed rotation, thereby forming a large specific surface area and rapidly updating phase interface, achieving sufficient contact between gas and liquid. When passing through narrow channels on the interception ring, due to mechanical rotation collision, liquid film capture, and the filtering effect of fog droplets on low solubility gases, it has strong selectivity for capturing sulfur-containing gases such as H2S and SO2; At the same time, the rotating cutoff ring exerts a strong shear stress on the new liquid, causing it to be cut into thin liquid films and fine droplets. At the same time, the channels of gas and liquid constantly change direction due to the rotation of the cutoff ring, greatly increasing the gas-liquid contact time and providing a good place for the coarsening of soluble gases and liquids; On the other hand, when gases containing impurities such as H2S and SO2 pass through a cutoff channel, the large gas-liquid contact area (specific surface area) and rapidly updated interface provide a fast reaction site for desulfurization, defluorination, dechlorination and other reactions, thereby achieving efficient desulfurization, defluorination, dechlorination and other acidic gases that can be applied in principleHigh gravity interception wet desulfurization equipmentRemoval of impurity gases.

The interception wet desulfurization equipment has the following advantages:

1. With a small liquid to gas ratio, while ensuring high desulfurization efficiency, the liquid to gas ratio is lower than other traditional equipment, which can reduce the circulation of absorption liquid and save power consumption.

2. The supergravity interception wet desulfurization equipment has the same purification ability for hydrophilic and non hydrophilic dust due to its special dust removal mechanism in capturing dust.

3. The pressure reduction of this technology can reduce the energy consumption of the fan.

4. The residence time of gas-liquid in the supergravity machine is very short. Due to the difficulty of CO2 dissolution in water, it can improve the selectivity of desulfurization, reduce the consumption of alkali and the generation of by-products.

5. Effectively suppressed the deposition and blockage caused by gas dust in the equipment.

6. Due to the significant enhancement of mass and heat transfer processes, the equipment has a small size, saves land, and is easy to make into a modular design with low energy consumption and strong adaptability.

7. Multiple desulfurizers can be used for desulfurization, such as alkali and composite desulfurizers.
