Acid Gas Scrubber Spray Tower Wet Air Purification Equipment
Use For Removal Of Harmful Gases Chemical Plant
Structural components
The structural design of the spray tower varies according to the type, flow rate and concentration of the gas to be treated, but it generally contains the following main parts:
(1) Tower body: Generally made of pp or stainless steel, with a round or square shape. Inside the tower body, there are usually fillers, nozzles or filler layers to increase the gas-liquid contact area.
(2) Nozzle: Used to atomise the liquid and spray it into the path of the exhaust gas flow. The design of the nozzle affects the size and distribution of the liquid droplets and thus the gas-liquid contact effect.
(3) Liquid Circulation System: Includes liquid supply pumps, piping, level control and other devices used to provide treatment fluid (e.g., water or chemical solution) to the spray tower.
(4) Gas import and export: the waste gas enters the tower through the air inlet, and the purified gas is discharged from the top of the tower.
Wastewater discharge system: The treated wastewater is discharged from the bottom of the tower and discharged or recycled after necessary treatment.
(5) Packing layer (optional): Some spray towers are equipped with packing layer inside to increase the gas-liquid contact area and enhance the purification effect.
| Size(⌀*H/mm) | 1000*3500 | Material | PP |
| Shell Thickness(mm) | 6 | FiltrationVelocity(m³/h) | 3000~5000 |

Advantages
(1) High treatment efficiency: the spray tower can efficiently remove acid gases, particles and some aerosols from exhaust gases.
(2) Strong adaptability: for different kinds of exhaust gases, the spray tower can choose different treatment fluids (such as water, lye, acid or other specific solutions) according to the need, with good adaptability.
(3) Simple equipment: relatively simple structure, easy to install and maintain.
(4) Low operating costs: low energy consumption during operation and relatively simple wastewater treatment.
