Stainless steel UV photocatalytic oxidation deodorization purifier for waste gas treatment in wooden factory workshop

Wooden Furniture Industry

Definition: Refers to the production activity of making various types of furniture using natural wood and wood-based panels as the main materials, supplemented with other auxiliary materials such as paint, veneer materials, glass, hardware accessories, etc.

Production process and pollution generation process

The organic waste gas in the production of wooden furniture mainly comes from the volatilization of solvents in coatings and organic components in auxiliary materials, among which paint spraying is the main pollution link. The painting workshop for furniture production is equipped with a closed painting room. In order to reduce the emission of pollutants during the painting process, the painting room is equipped with a water curtain to absorb paint mist. The gas absorbed by the paint mist is then adsorbed and discharged through the exhaust pipe.

Other organic gas emissions include the painting process and drying process, during which organic solvents evaporate and produce organic waste gas emissions. Currently, most enterprises do not have sufficient control over the organic volatile pollutants emitted from these processes.

The painting, drying, and bonding processes of furniture should be carried out in the workshop. It is strictly prohibited to use paint, dry furniture, or perform bonding operations outdoors. It is also strictly prohibited to stack paint and empty paint buckets outdoors.

The workshop should have organic gas collection and purification devices with good sealing effect.

The volatile organic waste gas from workshop n needs to be centrally extracted and discharged through an exhaust system. The workshop should be equipped with good ventilation equipment, and the ventilation facilities should achieve an hourly air exchange rate of6Above that, there is no obvious odor in the space outside the workshop in the factory area.

For those using adsorption methods, activated carbon and other adsorbents should be replaced regularly, and detailed replacement records should be kept for at least three years; Facilities using combustion methods must operate normally.

After using the paint, promptly seal the container mouth (including empty containers) to prevent spillage.

Furniture that has been painted should not be stored outdoors and should be promptly stored in the warehouse.

Strengthen the quality control of raw materials. For furniture production using artificial boards as raw materials, the formaldehyde emission of the artificial boards used should comply with the "Formaldehyde Emission Limits for Indoor Decoration Materials, Artificial Boards and Their Products"（GB18580-2001）The requirements; The quality of the coating should comply with the "Limit of Harmful Substances in Solvent based Wood Coatings for Interior Decoration Materials"（GB18581-2001）The relevant requirements.

Waste gas treatment technology in the wooden furniture industry

Pre treatment equipment for exhaust gas in the wooden furniture industry (depending on the specific project and actual working conditions of the exhaust gas source, it may involve corresponding pre-treatment measures such as dust removal, water vapor separation, high temperature cooling treatment, oil and grease removal, acid alkali water mist removal, etc.) plasmaUVPhotolytic deodorization exhaust gas purifier with high emissions.

Plasma photolysis exhaust gas decomposition deodorization purifier

【 Working Principle 】

This device is a plasma decomposition exhaust gas purifier+UVThe perfect combination of two devices, a photocatalytic deodorization exhaust gas purifier, combines the advantages of plasma exhaust gas purifier and ultraviolet catalytic deodorization exhaust gas purifier, using plasma decomposition technology andUVCombining UV photolysis technology for efficient synergistic purification of exhaust gases and odors!

（1）After the exhaust gas and odorous gas enter the integrated equipment, they pass throughUVIn the ultraviolet beam region, when irradiated with high-energy and high-efficiency ultraviolet light waves, an instantaneous photolysis reaction occurs, opening the chemical bonds between exhaust gas and odor pollutants, damaging their molecular structure and nucleic acids; The use of high-energy ultraviolet light waves to decompose oxygen molecules in the air produces free oxygen, also known as reactive oxygen species. Due to the imbalance of positive and negative electrons carried by free oxygen, it needs to combine with oxygen molecules to produce ozone, which oxidizes pollutants in a free state into small molecule harmless or low-risk compounds. asCO₂TheH₂OWait.UV+O₂→O-+O^*(reactive oxygen species)O+O₂→O₃(ozone).  

（2）The exhaust gas and odorous gas pass through the plasma electric field area, and within the nanosecond time range, the plasma fiercely bombards the pollutant molecules such as exhaust gas and odorous gas, generating fission and decomposition reactions, producing various active free radicals, high-energy electrons, high-energy ions, etc. with high concentration, intensity, and energy. At the same time, a large amount of mixed gases such as ozone, atomic oxygen, and ecological oxygen are produced, and a series of complex differentiation, cracking, and oxidation-reduction reactions are carried out.

（3）UVUV photolysis and plasma decomposition efficiently synergistically produce a series of photolysis and decomposition reactions, which are then subjected to a composite multi-stage purification process to meet emission standards! It can safely and efficiently purify and treat various harmful exhaust gases, as well as efficiently and cleanly remove various odors.

1) High purification efficiency and stable operation.

2) Compact structure, innovative design, small size, light weight, and convenient transportation.

3) Noise ≤45dB（A）Equipment wind resistance ≤100Pa.

4) Low operating costs and energy consumption.

5) UV oxidation decomposition+carbonization technology.

6) Easy to install and operate.

7) Easy to clean and maintain, with a long service life.

【 Precautions 】

1. To ensure the purification efficiency of the equipment, the fan should be located behind the exhaust gas purifier.

2. When installing the exhaust gas purifier on the bracket, it should be securely connected to the bracket; The connection between the exhaust pipe and the exhaust pipe must be sealed.

3. The exhaust gas purifier should be installed outdoors with sufficient space for maintenance and repair; When installing outdoors, a rainproof and sunshade canopy should be installed,To avoid affecting the normal service life of the exhaust gas purifier and increasing unnecessary maintenance costs.

4. To ensure the purification efficiency of the exhaust gas purifier, the variable diameter air duct connected to the inlet and outlet of the equipment should be as smooth as possible.

5. The exhaust gas purifier box should be safely and reliably grounded; During installation, it is not allowed to bump the electrodes. It is strictly prohibited for foreign objects to fall into the purifier.
