Acid tail gas scrubbing tower&Phe; 2600mm material FRP

The acid tail gas scrubbing tower is made of FRP vertical cylindrical material with a diameter of 2600mm. A liquid storage tank is installed at the bottom, and gas-liquid counter current contact is used to neutralize the acidic waste gas by spraying alkaline solution.

Acid tail gas scrubbing tower processing capacity:

Empty tower flow rate: 0.8-1.2m/s, to avoid liquid flooding

Processing air volume: approximately 120000 to 150000 m ³/h

Suitable for working conditions: Suitable for processing acidic waste gases from medium and large chemical, electroplating, acid pickling lines, etc

Design parameters for a Φ 2600mm acid tail gas scrubbing tower

Tower wall thickness: 8-10mm (severe corrosive environment)

Packing specification: PP material Ball ring/step ring (φ 50mm), stacking height 2.0-3.0m, increasing mass transfer area

Spray system: 2-3 layers of high-pressure spiral nozzles, coverage rate>95%, liquid to gas ratio 2-3L/m ³

Mist removal device: combination of swirl plate and baffle plate, with a mist droplet content of less than 50mg/m ³ at the outlet

Acid tail gas scrubbing tower with a diameter of 2600mm made of FRP component:

Inlet section: Tangential or radial intake, evenly distributed airflow

Spray layer: Multi layer cross arrangement, spray particle size 50-100 μ m, ensuring sufficient gas-liquid contact

Packing layer: Regular packing, extending contact time, improving absorption efficiency

Mist removal layer: Separate and purify liquid droplets in the gas to prevent secondary pollution

Circulating system: acid resistant pump+pipeline+pH control system to maintain absorption efficiency

Process flow of acid tail gas scrubbing tower

Exhaust gas entering: Acidic exhaust gas enters from the bottom and comes into contact with the alkaline spray liquid from top to bottom in reverse flow

Neutralization reaction: H ⁺ (acidic)+OH ⁻ (alkaline) → H ₂ O+salt (such as HCl+NaOH → NaCl+H ₂ O)

Purified emissions: The treated gas is discharged from the top through a defogging layer to meet emission standards

Waste liquid treatment: Circulating liquid is regularly discharged or regenerated to maintain a pH value within the range of 8-10

FRP acid tail gas scrubbing tower with a diameter of 2600mm. Application scenarios:

Chemical industry, electroplating/surface treatment, electronics industry: circuit board cleaning, semiconductor manufacturing, metallurgy/metal processing, pharmaceuticals/food: acidic process exhaust gas, fermentation exhaust gas
