Activated Carbon Tank, Odor Adsorption, Industrial Waste Gas Purification

Product Description

Scope of application

1. Surface Coating Industry: Applied in painting/spraying workshops of automobiles, furniture, and home appliances. It treats benzene, toluene, xylene, and resin volatiles contained in paint mist, preventing waste gas from irritating the respiratory tract of operators while meeting the VOCs emission requirements of environmental protection regulations.
2. Printing & Packaging Industry: Used in processes such as flexible plastic packaging, color printing, and book printing. It adsorbs solvent waste gases (e.g., ethanol, ethyl acetate, ketones) volatilized during ink drying, eliminating pungent odors in workshops and improving the working environment.
3. Chemical & Pharmaceutical Industry: Employed in chemical synthesis, solvent recovery, and pharmaceutical intermediate production. It handles organic waste gases (e.g., methanol, acetone, dichloromethane) and some toxic gases (e.g., small amounts of chlorinated hydrocarbons), preventing direct emission of waste gas from polluting the atmosphere.
4. Rubber & Plastic Industry: Utilized in rubber vulcanization, plastic granulation, PVC processing, and other links. It removes odorous gases (e.g., olefins, sulfides) and reduces the impact of odors on the environment around the factory.
5. Municipal Environmental Protection Field: Applied in sewage treatment plants (treating odorous gases such as hydrogen sulfide and ammonia generated in aeration tanks and sludge dewatering rooms), waste transfer stations/landfills (adsorbing volatile odorous substances from garbage decay), and kitchen waste treatment plants (removing acidic odors from oil decomposition).
6. Food Processing Industry: Used in aquatic product processing (fishy smell from processing seafood like fish and shrimp), meat curing (humus smell from marinating and fermentation), and grain processing (moldy smell from grain mildew). It reduces the impact of odor diffusion on surrounding residents through adsorption.
7. Catering & Hotel Industry: Employed in post-treatment of oil fumes in large catering kitchens (adsorbing oil volatiles and pungent odors in oil fumes) and fresh air purification of hotel central air conditioners (removing outdoor odors or formaldehyde residues from indoor decoration to improve indoor air quality).

 

How it works

 

Activated Carbon Tank (alias: Activated Carbon Adsorption Tank/Activated Carbon Tower) - a waste gas treatment device based on activated carbon's physical adsorption, mainly removing industrial waste gas components like VOCs, toxic/harmful gases and odors. Widely used in environmental protection, it is key for enterprises to meet waste gas discharge standards and improve workplaces.

 

1. Gas Uniform Distribution: Pollutant-containing waste gas (e.g., spray painting waste gas, printing waste gas) is drawn into the activated carbon tank by a fan, and evenly distributed via internal devices such as flow deflectors and air distribution nets-preventing uneven adsorption caused by excessively high local gas concentration.
2. Adsorption Filtration: When the waste gas passes through the activated carbon filling layer, VOCs (e.g., benzene, toluene, formaldehyde) and odorous molecules (e.g., hydrogen sulfide, ammonia) are "trapped" in the micro-pores of the activated carbon. The purified gas (with a pollutant removal rate typically 80%-95%) is discharged from the top of the tank.
3. Regeneration/Replacement: As usage time increases, the micro-pores of the activated carbon are gradually filled with pollutants, leading to decreased adsorption capacity (evidenced by higher pollutant concentration in the discharged gas and increased resistance). At this point, thermal regeneration (heating to 80-120°C to desorb pollutants for activated carbon reuse) or direct replacement (commonly used for small and medium-sized equipment) is required to restore purification capacity.

1. Easy Operation: No complex control system is required-only regular checks on the activated carbon status are needed. Small and medium-sized equipment can be maintained manually.
2. Controllable Cost: The initial equipment investment is low; activated carbon can be reused after regeneration (reducing consumable costs), and the only energy consumption during operation is for the fan.
3. No Secondary Pollution: Adsorbed pollutants can be recovered through regeneration (e.g., acetone in solvent waste gas can be recycled for reuse), and the purified gas is discharged up to standard.

 

Technical features

 

Avoid High Temperature & Humidity: The adsorption capacity of activated carbon decreases when the temperature exceeds 40°C, and it is prone to moisture absorption and caking when humidity exceeds 80%. Preheaters and dehumidification equipment should be used (especially in humid southern regions).

 

Inapplicable to High-Concentration Waste Gas: If the VOCs concentration in the waste gas exceeds 2000mg/m³, the adsorption cycle of activated carbon is short (replacement may be needed every 1-2 days). It is recommended to first reduce the concentration via a "concentration device" before the gas enters the activated carbon tank.

 

Fire & Explosion Protection: When treating flammable waste gases (such as solvents and alcohol), the tank body must be grounded for static protection; "flame-retardant" activated carbon should be selected, and supporting explosion-proof fans and fire-extinguishing devices are required.

Frequently asked questions

I. Product Types and Characteristics

 

Q: What are the main types of your biogas flares?
A: We mainly have enclosed biogas flares and open biogas flares. Enclosed biogas flares can better control the combustion process and reduce noise and heat radiation; open biogas flares have the characteristics of simple structure and lower cost.
 

Q: What are the advantages of different types of biogas flares?
A: Enclosed biogas flares have high safety performance and little impact on the surrounding environment, and are suitable for places with high requirements for environmental protection and safety. Open biogas flares are relatively easy to install and maintain and are suitable for projects with limited budgets or less strict requirements for combustion effects.
 

II. Parameter Specifications

 

Q: What are the main parameters of biogas flares?
A: The main parameters include processing capacity (cubic meters/hour), combustion temperature range, ignition method, wind resistance capacity, equipment size, etc.

 

Q: How is the processing capacity determined?
A: The processing capacity depends on the amount of biogas generated in the project. We can accurately calculate according to the biogas generation data you provide and recommend a suitable processing capacity specification for you.

 

Q: What is the impact of combustion temperature on use?
A: A higher combustion temperature can ensure that biogas is fully burned and reduce harmful substance emissions. But too high a temperature may also damage the equipment, so a suitable combustion temperature needs to be selected within a safe range.
