Main components of industrial smoke extraction systems:
The industrial smoke extraction system is a comprehensive solution, designed to be customized to the specific needs of each project. The basic structure of the system includes stainless steel hood, duct, exhaust fan motor, oil separator system, damper, and filter. However, depending on the characteristics of the space and technical requirements, some components may be adjusted or eliminated to optimize performance and cost.
Let’s explore with Saigon Horeca the detailed structure of a professional smoke extraction system:
Smoke extraction
Fume extractor is the first and most important part of the industrial smoke extraction system. It acts as a “cone” that covers the area that produces smoke, dust, and odors, thereby collecting and sending them into the duct system for treatment.
Fume hoods help maintain a clean and safe working environment. With its optimal design, it effectively collects smoke, dust and other pollutants, bringing fresh air to the kitchen space. Not only that, the smoke hood also protects the equipment from adhering dirt, prolongs its life and improves operating performance. Besides, it eliminates odors and dust, creating a cool and pleasant working environment. In particular, in the event of a fire, the smoke hood plays a role in preventing the spread of fire and smoke, ensuring safety for everyone.
Smoke Duct
Fume duct is an indispensable component in the industrial smoke extraction system. It acts as an air pipeline, bringing smoke, dust, and grease vapor from the suction hood to processing equipment or directly into the environment.
Fume pipes can have many different shapes such as round, square, rectangular, depending on the installation space and design requirements. Pipes are often designed with stiffening ribs to ensure rigidity and withstand the pressure of the air flow. Usually made of high-grade 304 stainless steel, has good heat resistance and corrosion resistance, ensuring durability and hygiene.
Main function:
- Fume ducts are responsible for carrying exhaust gases from the hood to treatment equipment such as exhaust fans, filters, or chimneys.
- Prevent dust and odors from escaping into the environment, ensuring a clean working space.
- Prevents dirt from sticking to other devices in the system, prolonging life.
Installing smoke ducts requires high technology to ensure the system operates effectively and safely. The joints need to be sealed or use rubber gaskets to avoid air leakage.
Some notes when installing:
- Avoid too much kinking: Too much kinking will reduce airflow speed and increase resistance.
- Ensure tightness: Joints must be sealed or use rubber gaskets to avoid air leakage.
- Proper installation: You should ask professional construction units to ensure quality.
Smoke Extractor Fan Motor
Smoke exhaust fan motor is the part that provides the driving force for the entire smoke extraction system. Thanks to the strong suction force, the fan motor creates a high pressure, pushing exhaust gases, dust and odors out of the kitchen space, through the duct system and filtering devices.
The fan motor plays an essential role in the smoke extraction system, being the source of suction force, helping to remove pollutants from the air. It determines the air flow through the system, ensuring effective smoke extraction and maintaining a clean environment. At the same time, the fan motor creates pressure to push exhaust gas through the ducts and filter equipment, ensuring the system operates smoothly and efficiently.
The structure of the hood includes main components such as the impeller, the motor, and the fan cover. When the electric motor starts, it provides energy for the impeller to rotate at high speed, creating a vacuum area behind. This helps draw in air, effectively collecting smoke and dust. The fan cover not only protects internal components from damage but also directs airflow in the right direction, ensuring optimal performance and maintaining a healthy workspace.
Oil Separation System
Oil separation system plays an important role in removing grease from exhaust gas, helping to protect the environment and increase the life of equipment.
The oil separation system operates based on physical principles, taking advantage of the density difference between oil and air. When exhaust gas containing grease passes through the system, grease particles will be trapped on filter plates or specially structured surfaces.
Sound Absorbing Air Duct
Sound-absorbing duct is useful in minimizing noise generated from system operation. Thanks to that, the workspace becomes quieter, ensuring a comfortable working environment for users.
Why do we need sound-absorbing air ducts?
- Noise from the smoke extraction system can cause discomfort, affecting human health and work efficiency.
- Reduce noise to the surrounding environment, ensuring quality of life for the community.
- Reduce vibration, protect other devices in the system.
Benefits of using sound-absorbing air ducts:
Sound-absorbing air ducts bring many important benefits to the workspace. First of all, it creates a quiet environment, helping workers concentrate more and thereby increase productivity. At the same time, sound-absorbing ducts also protect health by minimizing the negative effects of noise. With a beautiful design, it not only increases the aesthetics of the space but also contributes to compliance with state noise regulations, ensuring the system operates within the allowed threshold.
Operating principle of smoke duct
Industrial smoke extraction systems operate on the principle of pressure and air rotation to suck smoke and polluted air out of the working environment, transport them through the treatment system and exhaust them outside. Below is a detailed description of the working principles of this system:
Creating negative pressure: Industrial exhaust fans are installed in the central area to create negative pressure at the location where smoke is needed. This negative pressure helps absorb air and smoke in the work area, ensuring effective smoke extraction.
Smoke and polluted air extraction: With negative pressure created, air and smoke in the work area are sucked through suction pipes or ducts. Industrial exhaust fans create continuous air flows, sending them into filters or smoke treatment equipment.
Filtering and treatment: In a smoke extraction system, air and smoke are passed through filters to remove dust particles, pollutants and unpleasant odors. Common filters include dust filters, activated carbon filters, chemical filters, and additional types of filters depending on the type of smoke and toxins to be removed.
Discharge or additional treatment: Once purified, the air can be released into the environment through the exhaust system if no contaminants remain. In some cases, smoke and toxins need additional treatment before being released to ensure environmental safety.
Control and adjustment: Industrial fume extraction systems are controlled and controlled through automation devices, including pressure sensors, controllers and pressure control valves. These devices ensure stable system operation and maintain negative pressure in the system, optimizing smoke and polluted gas removal efficiency.
Air conditioning and purification: Modern industrial smoke extraction systems are also equipped with the ability to supply fresh air into the working space. This not only regulates but also purifies the air, creating a fresh working environment and protecting human health.
