Acid alkali washing tower

Acid alkali washing towerWorking Principle:

Acidic gas enters the purification tower along the tangential direction from the inlet below the tower body. Under the power of the ventilation fan, it quickly fills the space in the inlet section and then uniformly rises through the equalization section to the absorption section of the * stage packing. On the surface of the filler, acidic substances in the gas phase react chemically with alkaline substances in the liquid phase. The reaction product oil (mostly soluble salts) flows into the lower storage tank with the absorption solution. The unabsorbed acidic gas continues to rise and enter the * stage spray section. In the spray section, the absorbing liquid is sprayed at high speed from uniformly distributed nozzles, forming countless small droplets that are fully mixed, in contact with the gas, and continue to undergo chemical reactions. Then the acidic gas rises to the second stage packing section and spray section for a similar absorption process as the * stage. The second stage and the first stage nozzles have different densities, spray pressures, and absorption ranges of acidic gas concentrations. The process of contact between the spray section and the packing section is also a process of material heat and mass transfer.

‌Acid alkali washing towerThe advantages mainly include the following aspects:

Strong corrosion resistance: The main material of the acid-base washing tower is fiberglass, which has excellent corrosion resistance and can resist the erosion of strong acids, strong alkalis, and various chemicals, ensuring the long-term stable use of the washing tower under harsh environmental conditions. Compared with traditional metal materials, the corrosion resistance of fiberglass significantly reduces maintenance and replacement frequency, thereby reducing long-term usage costs.

Lightweight and high-strength: Fiberglass material has lightweight characteristics, making the tower structure relatively lightweight and easier to install and transport. A lighter tower body can reduce the requirements for supporting structures, simplify the installation process, and lower installation costs. In addition, fiberglass material also has high strength and can withstand certain mechanical pressure and impact, ensuring the safety and durability of the tower body.

Efficient purification: The acid-base scrubbing tower can effectively remove harmful substances from the exhaust gas by spraying liquid and fully contacting it with the exhaust gas. Its internal structure is improved through optimized packing and spray system, which increases the contact area between gas and washing liquid and enhances gas purification efficiency.

Stable and reliable: The acid-base washing tower has a simple structure, easy operation, low maintenance costs, and stable and reliable operation, which can maintain high purification efficiency for a long time. Its equipment is made of sturdy materials, operates stably and reliably, has strong adaptability, and can adapt to different concentrations and properties of exhaust gas treatment needs.
