PP Material Activated Carbon Adsorption Equipment Exhaust Gas Treatment Purification Air Cleaning Plant

High-efficiency activated carbon attachment device can quickly absorb pollutants in exhaust gas. The exhaust gas containing pollutants is powered by a fan and enters the activated carbon adsorber under negative pressure. Since there is unbalanced and unsaturated molecular attraction or chemical force on the solid surface of activated carbon, when the solid surface comes into contact with the gas, it can attract The gas molecules are concentrated and kept on the solid surface, and the pollutants are thus adsorbed. After the exhaust gas passes through the filter, it enters the dust exhaust system of the equipment, and the purified gas is discharged at high altitude to meet the standards.

The main function of an activated carbon adsorption box is to purify toxic, harmful, and odorous waste gases generated during industrial production. It is a highly efficient dry waste gas treatment device that utilizes the large specific surface area and excellent adsorption capacity of activated carbon to remove pollutants from the air.
 
For exhaust gases containing large amounts of dust or oil mist, a dry filter or other pretreatment equipment is usually added before the activated carbon adsorption box to prevent clogging and extend its service life.

Working Principle

Activated carbon adsorption tower has the advantages of high adsorption efficiency, wide application, convenient maintenance, and can simultaneously deal with a variety of mixed waste gas, etc. Activated carbon has the function of removing formaldehyde, benzene, TVOC and other harmful gases and disinfection and deodorization.Activated carbon adsorption tower is widely used in the production of electronic components, battery production, pickling operations, laboratory exhaust, metallurgy, chemical, pharmaceutical, painting, food, brewing and other waste gas treatment, which is suitable for spray paint waste gas treatment purification.

Features

.Technology Integration: Typically consists of multiple integrated units such as exhaust gas collection, pre-treatment, core purification, post-treatment, automatic control, and energy management, forming a synergistic working system.
. High Adaptability: Flexible selection or combination of various treatment technologies based on specific parameters of the waste gas, such as composition (e.g., hydrocarbons, alcohols, benzene series), concentration, flow rate, temperature, and humidity.
 .Environmental Adaptability Design: In special regions (e.g., high-altitude areas like Qinghai with significant temperature variations), equipment requires specialized optimizations in sealing, material weather resistance, combustion efficiency, etc., to ensure stable operation.
. High Safety and Reliability: As most organic waste gases are flammable and explosive, the system is commonly equipped with safety facilities such as explosion-proof devices, flame arresters, concentration monitoring and alarm interlock systems, and emergency exhaust.
.High Level of Intelligence: Utilizes an automated control system that monitors real-time parameters like concentration, temperature, and pressure through sensors, enabling automatic start/stop, mode switching, and fault alarm, thereby reducing manual intervention risks.

Functions

1.Exhaust Gas Collection & Pre-treatment: Collects waste gases from production sources via hoods and ducting systems, removing particulates, paint mists, water mists, and other impurities through filters to protect subsequent core equipment:

2.Core Purification & Recovery: 
. Adsorption Technology: Utilizes activated carbon or zeolite to adsorb organic compounds from low-concentration waste gas. After saturation, the concentrated organics are recovered via thermal desorption, enabling resource reuse.
. Thermal Oxidation: Oxidizes organic compounds into CO and HO at high temperatures (typically >760C), suitable for medium to high concentration waste gas. Can be equipped with heat recovery units for energy conservation.
. Catalytic Oxidation: Achieves oxidation at lower temperatures (200400C) with a catalyst, consuming less energy than direct combustion. Requires precautions to prevent catalyst poisoning.
. Biological Treatment: Uses microorganisms to degrade biodegradable organic compounds, featuring low operating costs. Suitable for low-concentration, high-flow-rate waste gases.
 . Condensation Method: Recovers high-boiling-point organic compounds by cooling and condensation, often used as a pre-treatment for high-concentration waste gases.

3.Post-treatment & Compliant Emission: Applies secondary adsorption or scrubbing to the purified gas to ensure final emissions comply with national or local environmental standards.

4.Energy Recovery & Resource Utilization: Recovers waste heat from the oxidation process to preheat inlet gas or for other heating purposes. Alternatively, reuses the desorbed or condensed recovered organics to lower operating costs.
