UV Lamps: More Thoroughly Decompose Odors, Helping Meet Oil Fume Purification Standards

In cooking and baking environments where oil fumes are generated, in addition to visible oil mist particles, the pungent odors associated with them are also a source of concern. These odors are primarily caused by volatile organic compounds (VOCs) produced during high-temperature cooking. If these odors are treated solely with equipment that filters out the particles, the odors will still spread into the environment, affecting nearby residents and even leading to environmental complaints. UV lamps are targeted devices for odor removal, effectively breaking down organic odor molecules. They are often used in conjunction with other purification equipment for more comprehensive fume purification.

1. Working Principle: UV light decomposes odors, eliminating the need for consumables and reducing the hassle

The core of UV lamps is the use of ultraviolet light of a specific wavelength to disrupt the chemical structure of odor molecules, thereby achieving odor removal. The entire process eliminates the need for consumables such as filters. This process can be divided into two steps:

1. Ultraviolet Irradiation

The module is equipped with a UV lamp that emits a specific wavelength. When odorous fume passes through the module, the UV light penetrates the chemical bonds of the odor molecules. The 254nm wavelength of UV light primarily targets organic odor molecules, altering their molecular structure. The 185nm wavelength of UV light further breaks down some small molecules into harmless components such as carbon dioxide and water.

2. Ozone-Assisted Purification

Under the influence of the 185nm wavelength of UV light, oxygen in the air is converted into a small amount of ozone. Ozone has a strong oxidizing property and can react with odor molecules that haven't been completely broken down by UV light, further oxidizing them into harmless substances. It also inhibits bacterial growth and reduces the potential presence of microorganisms in cooking fumes, resulting in a more comprehensive purification effect.

2. Core Advantages: Adaptable to Multiple Scenarios, Complementing the Shortcomings of Traditional Purification

Compared to methods that rely solely on activated carbon for odor absorption, UV lamps offer significant advantages in odor treatment and are more adaptable to the needs of diverse scenarios:

1. More thorough odor removal without secondary pollution.

Activated carbon absorbs odors through the physical adsorption capacity of its pores. Once saturated, if not promptly replaced, odors may be released again, causing secondary pollution. UV lamps, on the other hand, treat odors through chemical decomposition, converting odor molecules into harmless substances. As long as the equipment is operating normally, it continues to function without causing secondary pollution. They are particularly suitable for applications requiring long-term, stable odor removal, such as restaurant kitchens and large bakeries.

2.No frequent replacement of consumables is required, reducing operational and maintenance costs.

Activated carbon filters require regular replacement, which incurs significant consumables costs over time. The replacement process also requires downtime, disrupting operations. The core component of a UV lamp is the UV tube. High-quality tubes have a lifespan of up to 9,000-1,000 hours. During this time, only regular cleaning of the tube surface is required to ensure UV penetration efficiency, eliminating the need for frequent consumable replacement. This significantly reduces operational costs and operational hassles for merchants.

3. Highly adaptable and flexible with other equipment.

The UV lamp is compact and can be used in conjunction with electrostatic precipitators and other equipment to address end-of-line odors, depending on specific purification needs. For example, in a restaurant kitchen purification system, an electrostatic precipitator first removes oil mist particles, and then the UV lamp decomposes any remaining odors. In coffee roasting applications, it can be combined with a smoke filter to remove burnt odors from roasting smoke, resulting in fresher exhaust air. This system can be adapted to meet the purification needs of different scenarios.

4.Stable operation and minimal environmental impact.

UV lamps primarily rely on ultraviolet (UV) lamps for operation. As long as the voltage is stable and the lamps are clean, they maintain a stable purification effect, unaffected by ambient temperature and humidity. They are suitable for long-term use in humid southern regions or in high-temperature cooking environments.

3. Applicable Scenarios: Use them in these scenarios to easily resolve odor issues

The characteristics of UV lamps make them important in a variety of scenarios requiring odor control:

In the catering industry, hot pot restaurants, barbecue restaurants, and other heavy-food restaurants produce large amounts of fumes with pungent, spicy, and burnt odors during cooking. Conventional purification equipment alone is difficult to completely remove odors. When used with UV lamps, these odor molecules can be effectively broken down, preventing nuisance, reducing complaints from surrounding residents, and helping businesses comply with environmental regulations.

In the food processing industry, coffee roasters and other establishments produce sweet or burnt fumes during the baking process. If these odors spread to the consumer area, they can affect the customer experience. UV lamps can be used in conjunction with baking fume filters to remove residual odors, keeping the air fresh and enhancing customer comfort.

In industrial production scenarios, oily fumes from some small food processing workshops and mechanical processing facilities can be accompanied by small amounts of organic odors in addition to oil mist particles. UV lamps can be used in conjunction with industrial fume purifiers to improve the workshop working environment and protect employee health.

Currently, UV lamps are available in various wattages and sizes. Merchants can choose the appropriate product based on their specific fume emissions, odor concentration, and existing purification equipment. Some manufacturers also offer customization services, tailoring equipment design to site conditions to ensure effective purification. For merchants struggling with odor, seeking long-term, stable purification, and controlling operational and maintenance costs, UV lamps are an ideal choice for enhancing fume purification effectiveness.
