Acid-Alkali Scrubbing Process
Process Overview
This process uses circulating acidic or alkaline scrubbing liquids to neutralize harmful gases through chemical reactions. It is mainly used to treat acidic gases (such as HCl, H2SO4 mist, HF) or alkaline gases (such as NH3).
Applications:
Electronics, electroplating, laboratories, chemical industry, metal cleaning, etc.
Main Advantages:
·High neutralization efficiency, typically over 95%;
·Simple operation and easy maintenance;
·Compact structure with a small footprint;
·Recyclable scrubbing liquid reduces operating cost;
·High safety, suitable for most corrosive gases.
Scrubbing + Activated Carbon Adsorption Process
Process Overview
In this combined process, the scrubbing tower removes water-soluble particles and part of the pollutants, while the activated carbon filters out the remaining organic gases through physical adsorption.
Applications:
Printing, painting, coating, rubber, electronics, and other industries involving VOCs emissions.
Main Advantages:
·High overall removal efficiency, effective for various gas types;
·Activated carbon can be replaced or regenerated as needed;
·Strong adaptability to a wide range of pollutants;
·Effective secondary treatment to meet strict emission standards.
Scrubbing + Organic Solvent Atomization Absorption
Process Overview
After initial treatment with a scrubbing tower, this process atomizes organic solvents to absorb non-water-soluble VOCs through physical or chemical means.
Applications:
Coatings, inks, petrochemicals, pharmaceuticals, and industries dealing with complex organic exhaust gases.
Main Advantages:
·Effective for high-concentration and hard-to-treat organic gases;
·Excellent absorption and deodorization performance;
·Solvents can be recycled to reduce operational costs;
·Suitable for multicomponent and non-polar gas treatment.
Baghouse Dust Collection Process
Process Overview
Using filter bags made of high-efficiency materials, this system captures dust from gas streams. The dust is periodically removed by mechanical shaking or pulse jet cleaning.
Applications:
Cement, metallurgy, foundries, chemicals, grain processing, and industries with heavy dust loads.
Main Advantages:
·Extremely high dust removal efficiency, up to 99% or more;
·Effective for fine and ultrafine particles (submicron level);
·Stable operation and capable of handling large air volumes;
·Enables recovery of dust as a resource, offering both environmental and economic benefits;
·Works well under high-temperature and high-concentration dust conditions.
