The purification of smokeless tube oil fume is an important and complex process, especially in the catering industry. Due to space constraints or environmental protection requirements, the application of smokeless tube oil fume purification equipment has become particularly critical. The following will introduce in detail the methods, principles, advantages and related equipment of smokeless tube oil fume purification.

Ⅰ.Principle of smokeless tube oil fume purification

Smokeless tube oil fume purification equipment mainly uses physical, chemical or electrical means to effectively separate, adsorb, filter and transform the oil fume, odor and harmful substances generated during the cooking process, thereby achieving the purpose of purifying the air. These devices often include multi-stage purification systems, with each stage targeting different types of contaminants.

Ⅱ. Main methods for purifying oil fume from smokeless tubes
1. Physical filtration method

Primary filtration: intercept large particles (such as oil droplets, food residues, etc.) in oil fumes through preliminary filtration devices such as metal mesh or filters to prevent them from entering subsequent purification units.

High-efficiency filtration: Use high-efficiency filters (such as HEPA filters) or electrostatic dust removal technology to further remove tiny particles and suspended matter in oil fume and improve purification efficiency.

2. Chemical adsorption method

Use adsorption materials such as activated carbon to efficiently adsorb gaseous pollutants (such as VOCs, sulfides, nitrogen oxides, etc.) in oil fumes to achieve the effect of purifying the air.

3. Electrical purification method

Electrostatic deposition: The tiny particles in the oil fume are charged through a high-voltage electric field, and then deposited on the dust collecting plate under the action of the electric field force to achieve the purification of the oil fume.

Plasma purification: The high-energy electrons and ions generated by the plasma generator are used to react with the pollutants in the oil fume and convert them into harmless substances.

Ozone photodecomposition method of oil fume: using ozone with a wavelength of 185nm to photolyze oil fume into carbon dioxide and water.

Ⅲ. Types of smokeless tube oil fume purification equipment

Common smokeless tube oil fume purification equipment on the market mainly includes the following types:

1. Ductless internal circulation range hood

The ductless internal circulation range hood is a new type of equipment that integrates the functions of oil fume purification, air circulation and cooling. It does not require traditional smoke exhaust ducts. After the oil fume is purified through an internal multi-stage purification system, the clean air is discharged back into the room to achieve "zero" emission of oil fume. This kind of equipment not only saves installation space, but also reduces later maintenance costs. It is especially suitable for places with no smoke exhaust conditions or limited smoke exhaust.

2. Electrostatic oil fume purifier

The electrostatic oil fume purifier uses the principle of electrostatic deposition to charge the tiny particles in the oil fume through a high-voltage electric field and deposit it on the dust collecting plate. It has the advantages of high purification efficiency and simple maintenance, and is widely used in catering, food processing and other industries. However, it should be noted that the electrostatic oil fume purifier needs to clean the dust collecting plate regularly to ensure the purification effect.

3. Plasma oil fume purifier

Plasma oil fume purifiers use plasma technology to react with pollutants in oil fume through high-energy electrons and ions, converting them into harmless substances. This kind of equipment has the advantages of high purification efficiency and wide application range, but it is relatively expensive.

Ⅳ. Advantages of smokeless tube oil fume purification

1. Save space: There is no need to install traditional smoke exhaust ducts, saving valuable kitchen space.

2. Reduce costs: Reduce the cost of pipeline installation and subsequent cleaning and maintenance.

3. Environmental protection and energy saving: achieve "zero" or low emission of oil fumes, reducing environmental pollution. At the same time, some equipment also has a waste heat recovery function, which can recycle and utilize the heat energy in the oil fume.

4. Improve air quality: Effectively remove harmful substances and odors in oil fumes, improving the air quality in kitchens and restaurants.

5. Strong adaptability: It is suitable for various places with no smoke exhaust conditions or restricted smoke exhaust, such as basements, supermarkets and restaurants, etc.

Ⅴ. Selection and installation of smokeless tube oil fume purification equipment

1. Selection principle

Select the appropriate equipment model and specifications based on the kitchen area, oil fume generation and emission requirements.

Prioritize products with high purification efficiency, simple maintenance, and low energy consumption.

Pay attention to the noise control performance of the equipment to ensure that it does not affect the normal operation of the restaurant.

2. Installation precautions

Make sure the equipment is installed in a well-ventilated location to avoid accumulation of oil fumes.

Correctly install and debug the equipment according to the equipment instructions to ensure that all functions operate normally.

Clean and maintain the equipment regularly to ensure purification effect and service life.

Ⅵ. In conclusion

Smokeless tube oil fume purification is an effective means to solve the problem of oil fume emission in the catering industry. By using equipment that combines physical filtration, chemical adsorption, electrical purification and other methods, efficient purification of oil fumes can be achieved. When selecting and installing smokeless tube oil fume purification equipment, comprehensive considerations and selections need to be made based on the actual situation to ensure that the performance and effect of the equipment meet the expected goals. At the same time, strengthening the maintenance and upkeep of equipment is also a key link to ensure the purification effect and service life.
