Polypropylene Packing Tower

The Xinda Chemical Polypropylene Packing Tower made in China is a gas-liquid mass transfer device primarily made of polypropylene. It is widely used in the chemical, environmental, and pharmaceutical industries. This packing tower's key functions including gas purification, solvent recovery, and pollutant removal. Its core advantage lies in the corrosion resistance and mechanical strength of polypropylene, and then makes it more suitable for treating acidic and alkaline gases, organic solvents, and waste gases containing pollutants. For example, it is used in the coking industry to separate gas impurities to improve product purity, and in the environmental protection field for waste gas and wastewater treatment.

Product Features

The equipment operates at atmospheric pressure and utilizes a counter current flow process like gas phase flows from bottom to top, liquid phase flows from top to bottom. It is suitable for applications such as acid mist purification, waste gas treatment, and solvent recovery. It is particularly well-suited for small and medium-sized towers and for handling corrosive media. And it significantly reduces operating costs and improves separation efficiency.

Main Material

Polypropylene Packing Towers are molded in one piece using polypropylene. Some units utilize graphite-modified polypropylene for enhanced high-temperature resistance and mechanical strength.

Key Components

Packing Layer: Polypropylene ball rings and plastic balls are commonly used, and greatly increases the gas-liquid contact area through their high surface area and wet ability.

Spray System: Consisting of nozzles, piping, and a pump, it evenly sprays the absorbent (water, chemicals, or vegetable/mineral oil) onto the packing layer.

Gas-Liquid Separation Unit: A demister is located at the top to separate entrained liquid droplets, and a waste liquid collection system is located at the bottom.

Working Principle

Waste gas enters the bottom of the Polypropylene Packing Tower and, as it rises through the packing layers, comes into contact with the spray liquid in the opposite direction. Pollutants are dissolved by the absorbent or removed by chemical reactions. The purified gas is discharged from the top of the tower, and the waste liquid is collected at the bottom for further treatment. For example, acidic waste gas can be neutralized with alkaline spray liquid, and organic waste gas can be recovered through solvent absorption.
