Scrubber Towers in PPH

The scrubber towers in PPH of Xinda Chemical from China is specially designed for treating highly corrosive and multi-component complex industrial waste gas.The tower body adopts high crystallinity polypropylene homopole (PPH) through the spiral extrusion and winding process, the overall weld-free, excellent sealing and corrosion resistance, can withstand long-term hydrogen chloride, hydrogen fluoride, ammonia and a variety of organic volatils and other strong corrosive media of synergistic erosion.

The equipment integrates multiple functions such as spray absorption, efficient demisting and pre-dust removal. It can achieve the coordinated deep purification of acid mists, alkali gases, dust and some VOCs pollutants within a single tower body, solving the problems of single treatment and complex systems of traditional equipment.Its compact structure and reliable operation are especially suitable for semiconductor manufacturing, lithium battery material production, high-end chemical industry and other industries that require high corrosion resistance and purification efficiency of equipment.

Working principle

Scrubber towers in PPH is a kind of wet treatment equipment that uses gas-liquid contact reaction to purify waste gas. Its core principle is to separate harmful components and convert them into harmless substances through full contact between waste gas and washing liquid in the tower. The specific process is Waste gas containing pollutants enters from the bottom of the tower, is evenly distributed by the air distribution grid, and then moves upward. Meanwhile, the spray system sprays washing liquid (such as sodium hydroxide solution and other neutralizing agents) from the top.

In the packing layer (composed of materials such as quartz sand and activated carbon, used to increase the gas-liquid contact area), an environment where the gas and liquid phases fully react is formed. The acids, alkalis, toxic gases or particulate matter in the exhaust gas are removed through the effects of inertial collision, interception, aggregation and chemical neutralization. The purified gas is dehydrated and demisted through the top anti-fog baffle before being discharged, while the waste liquid is collected in the bottom water tank and discharged into the wastewater system for treatment or recycling.

Main Components

Advantages and technical features

Strong corrosion resistance: PPH (polypropylene) material, with excellent acid resistance, alkali resistance and corrosion resistance, can stable treatment H₂S, SOx, NOx, HCl, NH₃, Cl₂ and other corrosive gases, suitable for chemical, electroplating, semiconductor and other strong corrosion environment.

High purification efficiency: By optimizing the structure of the packing layer and the design of gas-liquid contact, Our scrubber towers in PPH ’s purification efficiency of acid and alkali waste gas and toxic gas can reach 85%-99%, especially in the treatment of low concentration, single source of pollution.

Compact structure and economy: The vertical structure design saves installation space and is suitable for both indoor and outdoor installation. The equipment is low in price, the treatment method is simple, the operating energy consumption is low, and it supports the recycling of absorption liquid, reducing the cost of chemicals.

Easy operation and maintenance: The system composition is simple. When starting up, the water pump should be turned on for 3 to 5 minutes before starting the fan. On a daily basis, only the pipeline valves, the proportion of chemicals and the motor rotation direction need to be checked to ensure that no debris enters and no components are loose.
