Advanced Environmental Protection Equipment For Industrial VOCs Control And Recovery

Equipment Description:

1. Working Principle ‌
‌Adsorption process‌: The exhaust gas is driven by a fan into the box, first passing through a pre-filter layer to remove dust, and then the activated carbon captures organic pollutants such as VOCs through physical adsorption (van der Waals force), purifying the gas to meet emission standards. ‌Desorption and regeneration‌ (optional): Some equipment supports steam or hot nitrogen desorption to achieve activated carbon regeneration and concentrated exhaust gas recovery‌. ‌

2. Technical parameters

3. Operation process ‌
‌1. Installation and commissioning ‌
‌Site selection requirements‌: good ventilation, away from fire sources, the equipment foundation must be horizontal and stable. ‌Pipeline connection‌: the air inlet is connected to the exhaust gas source, the air outlet is connected to the exhaust pipe, and the flange connection is sealed with a gasket to prevent leakage. ‌Electrical test‌: Check the fan steering, control system voltage (380V±5%) and grounding protection. ‌2. Operation monitoring‌
‌Start-up inspection‌: Confirm that the activated carbon is filled evenly and the pressure difference is ≤500Pa before starting the fan. ‌Daily inspection‌: Record the pressure difference change, the smell of the exhaust gas and the vibration of the fan. ‌3. Shutdown maintenance‌
‌Activated carbon replacement‌: When the pressure difference is ≥1200Pa, turn off the fan and empty the residual exhaust gas, wear protective equipment to replace the activated carbon. ‌Filter element cleaning‌: Clean the dust accumulated in the pre-filter layer every month to prevent blockage and affect the air volume. ‌

4. Applicable scenarios‌
‌Industrial waste gas treatment‌: VOCs purification in industries such as spraying, printing, and pharmaceuticals‌.
‌Laboratory exhaust‌: Treatment of low-concentration waste gases such as acid mist and organic solvents‌.
‌Odor control‌: Odor adsorption in garbage treatment stations and sewage treatment plants‌.

5. Precautions‌
‌Safety protection‌: Activated carbon is a flammable substance. Open flames are prohibited around the equipment and fire-fighting facilities are equipped‌.
‌Environmental compliance‌: Waste activated carbon is stored and transferred in accordance with hazardous waste regulations to avoid secondary pollution‌.

Main structures and components:

1. Main frame ‌
‌Box material‌: Made of carbon steel, stainless steel or galvanized sheet, it is corrosion-resistant and high-strength, and can withstand pressure and vibration during the adsorption process.
‌Structural design‌: It is divided into air inlet area, adsorption area and air outlet area, and the box has good sealing (equipped with sealing strips) to prevent gas leakage.
‌Maintenance design‌: A removable box door or quick-opening inspection port is set to facilitate the replacement of activated carbon and internal cleaning.
‌2. Core adsorption unit‌ ‌Activated carbon layer‌: Filled with granular, honeycomb or powdered activated carbon, with a specific surface area of ​​≥1200㎡/g, and captures pollutants such as VOCs through physical adsorption (van der Waals force).
‌Filling method‌: The volume of activated carbon and the amount of waste gas treated are configured in proportion (usually ≥1:5000) to ensure the balance between adsorption efficiency and gas residence time. ‌ ‌III. Pretreatment and airflow system‌
‌Pre-filter layer‌
‌Material‌: non-woven fabric, glass fiber, etc., intercept large dust particles in the exhaust gas (filtration efficiency ≥ 95%), and protect the activated carbon layer from clogging‌.
‌Layout‌: located at the front end of the activated carbon layer, combined with the airflow distributor to evenly disperse the gas‌.
‌Airflow distribution device‌
‌Guide plate/distributor‌: optimize the exhaust gas distribution, avoid local airflow overload, and improve the utilization rate of activated carbon‌.
‌IV. Power and air inlet and outlet system‌
‌Fan system‌: includes adsorption fan (drives exhaust gas in) and desorption fan (used in the regeneration stage), and the air volume can be adjusted to adapt to different working conditions‌.
‌Inlet and outlet‌:‌Air inlet‌: located on the side or bottom of the box, connected to the exhaust gas source pipeline through a flange‌. ‌Air outlet‌: set at the top or side, discharges purified gas, meets environmental emission standards‌. ‌V. Control and monitoring system‌
‌Sensor‌: integrated pressure, temperature and gas concentration monitors, real-time feedback of operating status‌.
‌Control unit‌: supports automatic adjustment of parameters such as fan speed and cleaning cycle to maintain adsorption efficiency‌.
‌VI. Regeneration and maintenance components‌
‌Regeneration mechanism‌: optional thermal regeneration (300-400℃) or steam desorption to restore the adsorption capacity of activated carbon‌.
‌Replacement structure‌: design drawer-type or modular activated carbon box to simplify the replacement process‌.
‌VII. Safety protection device‌
‌Explosion-proof design‌: equipped with pressure relief valve and spark prevention device to prevent spontaneous combustion or explosion of activated carbon‌.
‌Emergency shutdown‌: automatically cut off the power supply and start the alarm system under abnormal conditions‌.
Through modular structural design and multi-system collaboration, the activated carbon adsorption box can efficiently treat industrial waste gas and adapt to the VOCs treatment needs in spraying, chemical, pharmaceutical and other fields‌.
