Product Overview

The V0 PPs Flame-Retardant Activated Carbon Box is an activated carbon adsorption device made from V0 flame-retardant PPs board, used for treating VOCs organic waste gas and odors. The box is internally layered with activated carbon, where organic pollutants are adsorbed and purified as the waste gas passes through the carbon layer. Compared to conventional PP carbon boxes, its key feature is the use of V0 flame-retardant PPs board for the box body, offering superior flame-retardant performance while maintaining the advantages of PPs material, such as acid/alkali corrosion resistance, good flexibility, and ease of welding. It is suitable for indoor waste gas treatment applications where both organic gas emissions and corrosion/high fire safety requirements exist.

The adsorption of organic waste gas by activated carbon involves adsorption heat and a certain fire risk. Conventional flammable plastic boxes lack sufficient fire resistance for indoor and equipment-space use. V0 flame-retardant PPs board self-extinguishes quickly upon fire exposure, without flaming drips, in vertical burning tests, indicating a high flame-retardant grade. Using this material for the carbon box body, ducts, and internal components reduces the risk of ignition and flame spread, making it more suitable for installation in workshops, equipment layers, and near production equipment. The good flexibility and easy hot-melt welding of PPs board allow for customized non-standard dimensions and drawer structures based on airflow and site conditions.

Xicheng Environmental can design V0 PPs Flame-Retardant Activated Carbon Boxes based on treatment airflow, VOC composition, and on-site space. The boxes are equipped with honeycomb or granular activated carbon drawers, airflow distribution, and sealing structures. All box body materials, welding electrodes, and internal components are made of V0 flame-retardant PPs, offering acid/alkali resistance and high flame-retardant performance. Inlet and outlet ports are paired with PPs ducts, making them suitable for industries such as chemical, electroplating, electronics, and printing for adsorbing and purifying indoor organic and acid/alkali organic mixed waste gases.

Working Principle

The purification principle remains physical adsorption by activated carbon: under fan action, organic waste gas enters the box and passes through honeycomb or granular activated carbon layers. VOC molecules diffuse into the micropores of the activated carbon and are adsorbed on the surface. The purified gas is then exhausted. When the activated carbon becomes saturated, the drawer is removed for replacement. The V0 PPs box body itself does not participate in purification but provides a corrosion-resistant, flame-retardant, and sealed reaction space. The drawer structure ensures uniform airflow through the carbon layer, preventing short circuits.

The flame-retardant principle of V0 involves the flame-retardant system in the material inhibiting combustion upon contact with a fire source, causing the board to self-extinguish quickly after removal from the flame, and preventing flaming drips from igniting underlying objects, thereby keeping the fire risk of the equipment at a low level. It must be emphasized that the flame-retardant box reduces the risk of ignition and flame spread but does not eliminate the adsorption heat and safety risks of activated carbon adsorbing organic substances. It is still necessary to control inlet concentration and temperature, and to implement temperature monitoring and fire safety measures. The corrosion resistance principle originates from the polypropylene matrix, where PPs board is resistant to acid/alkali salt corrosion. When treating organic mixed waste gases containing acids or alkalis, the box does not rust or corrode, and welds are made with V0 flame-retardant electrodes, ensuring continuous corrosion and flame-retardant integrity.

Structural Components

The V0 PPs Flame-Retardant Activated Carbon Box consists of a V0 flame-retardant PPs box body, activated carbon drawers, activated carbon, distribution plates, inspection doors, sealing components, and legs. The box body is formed by cutting, bending, and hot-melt welding of V0 flame-retardant PPs board, with reinforced outer walls. Both the board and welding electrodes are V0 flame-retardant grade. Inside the box, rails and activated carbon drawers are installed in layers, with drawer frames and gratings also made of flame-retardant PPs.

The activated carbon drawers are filled with honeycomb or granular activated carbon, with flame-retardant porous plates on the windward and leeward sides. Sealing strips are embedded around the drawers, ensuring tight compression upon insertion to prevent short circuits and air leakage. An airflow distribution plate is installed on the inlet side. The box body has inlet and outlet flanges for connection with PPs ducts. Inspection doors, differential pressure gauge ports, temperature monitoring ports, and sampling ports are provided, with legs or a base at the bottom. Reinforced frames can be added to the box exterior to support the weight of the carbon layer. The overall structure is designed based on the full carbon weight of the equipment, ensuring secure lifting and support.配套风管、风阀 are also made of V0 PPs material to ensure consistent flame-retardant performance across the system.

Typical Process Locations

The V0 PPs flame-retardant activated carbon box is installed indoors or in equipment layers, located after pretreatment (filtering, washing, demisting) and before/after anti-corrosion fans. The exhaust gas is pretreated to remove dust, mist, and acid/alkali mists before entering the carbon box for VOC adsorption. The purified gas is discharged through PPs ducts and stacks. Space is left around the equipment for drawer extraction and carbon material replacement. The layout meets fire distance and fire lane requirements, and all connections with other equipment and ducts use V0 flame-retardant PPs materials to avoid flammable breaks in the system.

During installation, the box is mounted on a foundation and legs based on full carbon weight. After welding and assembly, the box seams and drawer seals are inspected, and the V0 flame-retardant certification documents for the plates are verified. Before operation, the activated carbon is loaded and recorded, and temperature and pressure differential monitoring are set up. During operation, the inlet organic concentration and temperature are controlled within safe limits to avoid direct high-concentration gas entry into the carbon box. Regularly check the carbon layer temperature, pressure differential, and outlet concentration. Saturated activated carbon is replaced and disposed of according to hazardous waste regulations. During shutdown, the carbon layer is purged with fresh air, and appropriate fire protection facilities are installed near the equipment.

V0 rating indicates that the enclosure material self-extinguishes quickly upon contact with a flame in standard combustion tests, demonstrating strong flame retardancy. This significantly reduces the risk of the enclosure being ignited by external heat sources and the spread of flames along the equipment. However, it does not guarantee that the equipment will never catch fire. Activated carbon adsorbs organic substances, releasing adsorption heat. When adsorbing high concentrations of VOCs or when the bed fails to dissipate heat properly, the carbon layer may heat up. Both activated carbon and organic substances are combustible. Therefore, even with V0-rated enclosures, it is still essential to control inlet concentration and temperature, implement temperature monitoring and alarms, and adopt fire protection and shutdown purging measures. Do not mistake material flame retardancy for process safety. The fire protection design of the entire adsorption system must comply with regulations.

Equipment installed indoors, on equipment floors, in basements, or in areas with high fire protection requirements, and handling organic exhaust gas, should prioritize the selection of V0 PPs flame-retardant carbon boxes, paired with V0 flame-retardant ductwork and dampers to meet building fire protection and safety requirements. When equipment is independently installed outdoors, with sufficient fire separation distance from the factory, and in areas with lower fire protection requirements, standard PPs or other material carbon boxes can be selected to control costs. Regardless of the material, safety measures for activated carbon adsorption processes cannot be omitted. Specific configurations should be based on building fire protection design and local review requirements, with V0 configurations recommended for critical locations.

The V0 PPs board is made by adding a flame retardant system to polypropylene, with the main material still being PPs. Its acid, alkali, and salt corrosion resistance performance is basically comparable to that of ordinary PPs, and it can handle general acid and alkali mists and organic exhaust gases without issues. However, some strong oxidizing agents or high-concentration special organic compounds may affect the material or flame retardant components. When treating complex mixed exhaust gases, the manufacturer should be provided with the gas composition, concentration, and temperature to verify material compatibility, and immersion testing may be necessary if required. When selecting materials, attention should be paid to both the flame retardant test report and corrosion resistance applicability—neither should be considered in isolation.

V0 PPs housing is acid and alkali resistant, capable of contacting acidic and alkaline mist gases. However, it is not recommended to allow large amounts of water mist or acidic and alkaline mist to directly enter the activated carbon layer in the process: liquid droplets will cause the activated carbon to become damp, block pores, and reduce adsorption capacity. Acids and alkalis may also react with the carbon or adsorbed organic substances. The proper approach is to first pass through spray washing and demisting to remove acidic and alkaline mist, then enter the activated carbon housing for adsorption of residual organic compounds, forming a washing plus adsorption combination process. The carbon housing should be in a dry or low-humidity airflow. This approach leverages the corrosion resistance of the PPs housing while protecting the activated carbon.

Need to provide the following parameters: airflow rate, VOC components and concentration, waste gas temperature and humidity, whether it contains acid-base mist and dust, required purification efficiency and emission standards, installation location (indoor or outdoor) and available space, flame retardancy level requirements for the housing and ductwork, and the orientation and size of the inlet and outlet ports. The airflow rate determines the cross-sectional area of the housing and the number of drawers, the components determine the type and loading amount of activated carbon, and indoor installation determines the V0 flame retardant configuration and external dimensions. After providing the parameters, the manufacturer designs based on the residence time and carbon layer thickness, and provides matching V0 flame retardant ductwork, dampers, and monitoring instruments.

Acceptance includes aspects of materials, structure, and performance. For materials, verify the V0 flammability rating certificate for the box body, welding rods, and internal components, and take samples for retesting if necessary. For structure, inspect weld quality, drawer quantity and sealing, airflow distribution plate, maintenance door, flange, and legs to confirm full carbon strength. For performance, test equipment resistance, inlet and outlet pollutant concentrations, and purification efficiency under design airflow, check if temperature and pressure differential monitoring are normal. For documentation, verify the activated carbon certificate of conformity, loading quantity, and replacement log requirements. The flammability rating certificate and treatment efficiency test report are important documents for indoor engineering acceptance.
