How to deal with smoke generated when laser cutting machine cuts materials

In the laser cutting machine industry, the smoke generated when cutting materials is an issue that cannot be ignored. These fumes not only affect the working environment, but may also pose a threat to the health of operators. Therefore, this article will introduce in detail several effective methods for dealing with smoke generated when laser cutting machines cut materials, aiming to help practitioners in the laser cutting machine industry better cope with this challenge.

‌1. Causes of laser cutting smoke‌

When the laser cutting machine cuts materials, due to the high energy density of the laser beam, the material quickly melts and vaporizes, and is blown away together with the high-speed airflow coaxial with the beam. This process is often accompanied by the generation of a large amount of smoke. These fumes mainly come from the combustion, vaporization of materials and the volatilization of molten materials.

‌2. Hazards of smoke‌

The smoke generated by laser cutting often contains a large amount of chemical components and tiny particles, which pose a serious threat to human health. Long-term inhalation of these fumes may lead to health problems such as respiratory diseases and skin diseases. In addition, smoke will pollute the working environment and affect the normal operation and maintenance of equipment.

‌III. Smoke treatment methods‌

‌Application of laser smoke purifier‌

Laser smoke purifier is a device specially designed to treat laser cutting smoke. It uses advanced technologies such as high-voltage electric field, activated carbon adsorption, photocatalyst decomposition, etc., which can effectively remove harmful substances in the smoke and reduce them to the national standard range. This equipment has the advantages of good treatment effect, stable operation, and convenient maintenance. It is a common smoke treatment method in laser cutting workshops.

‌Optimize the exhaust system‌

The exhaust system is also one of the effective means to treat laser cutting smoke. Through the reasonable design of the exhaust system, the air containing smoke can be discharged from the workshop, or recycled after purification. Local exhaust is usually aimed at the fixed position of the operator, and exhaust facilities are used to exhaust harmful substances from near the source; while comprehensive ventilation is applicable to the entire workshop, including natural ventilation and mechanical ventilation.

‌Use of industrial smoke purifier‌

Industrial smoke purifiers usually use high-efficiency filtering materials and technologies, such as microfiltration technology, to ensure that the smoke is thoroughly purified. This equipment is not only suitable for laser cutting machines, but also can be widely used in other industrial fields that produce smoke.

‌Application of photocatalytic technology‌

Photocatalytic technology is a new type of smoke treatment technology. It uses semiconductors and air as catalysts and light as energy to degrade organic matter into carbon dioxide, water and other non-toxic and harmless components. This technology has the advantages of high treatment efficiency, environmental protection and energy saving, and is particularly suitable for treating complex smoke components generated during laser cutting.

‌Installation of smoke detection and treatment device‌

In order to monitor and treat the smoke generated during laser cutting in real time, a smoke detection and treatment device can be installed. This device can detect the smoke concentration at the working position of the cutting head in real time, and automatically trigger the smoke treatment device for purification when smoke is detected. At the same time, it can also send out an alarm signal to remind the operator to take timely measures.

‌IV. Practical cases and effect analysis‌

Take a laser cutting company as an example. After the company introduced a laser smoke purifier and optimized the exhaust system, the smoke concentration in the workshop was significantly reduced, and the working environment was greatly improved. The health of the operators has also been effectively guaranteed, and the work efficiency and product quality have been improved. This case fully proves the effectiveness and practicality of the above smoke treatment method.

‌V. Conclusion‌

The smoke problem generated by laser cutting machines when cutting materials cannot be ignored. Through the rational application of laser smoke purifiers, optimization of exhaust systems, the use of industrial smoke purifiers, photocatalytic technology, and the installation of smoke detection and treatment devices, we can effectively reduce the smoke concentration and harmful gas emissions in the workshop, and provide operators with a safe and healthy working environment. At the same time, these measures will also help improve the production efficiency and product quality of enterprises, and contribute to the sustainable development of the laser cutting machine industry.
