When considering why the honeycomb-electric-field oil-fume purifier selects the tungsten needle as its core component, one must deeply understand the unique properties of the tungsten needle and its crucial role in the oil-fume purification process.
In brief, the working principle of the honeycomb-electric-field oil-fume purifier is to utilize an ionization-separation structure similar to the superposition of honeycomb cylinders. The cathode tungsten needle discharges, ionizing the oil-fume exhaust-gas molecules into positively-charged particles, which are then adsorbed by the surrounding anode tube wall to achieve the purification effect. In this process, the tungsten needle plays a vital role.
First of all, the tungsten needle has excellent mechanical, thermal, and electrical properties, and these properties are the key reasons it has become the preferred cathode material for honeycomb-electric-field oil-fume purifiers. Tungsten needles are generally made of high-quality tungsten alloys (tungsten content is above 98%) or pure tungsten (tungsten content is above 99.95%). They possess excellent electrical and thermal conductivity, high hardness, high strength, low impurity content, high tensile strength, good wear resistance, excellent ductility, and non-radioactivity.
Secondly, the tungsten needle can stably discharge in a high-voltage electric field, generating strong ionization energy and efficiently decomposing oil-fume particles. This feature significantly enhances the purification effect of the oil-fume purifier. At the same time, the tungsten needle also has strong high-temperature resistance and can operate for a long time under high load, thereby extending the service life of the oil-fume purifier.
So, in the high-voltage environment of the honeycomb-electric-field oil-fume purifier, these characteristics of the tungsten needle are fully utilized. In addition, the use of tungsten needles also reduces the energy consumption of the oil-fume purifier. Compared with traditional high-energy purification technology, the oil-fume purifier using tungsten needles has lower energy consumption while improving the purification efficiency. It is both environmentally friendly and economical, making it highly suitable for the green-development needs of the modern catering industry.
In summary, the honeycomb-electric-field oil-fume purifier chooses the tungsten needle as its core component because the tungsten needle has unique performance and advantages and can meet various requirements in the oil-fume purification process. The application of tungsten needles not only improves the purification efficiency and extends the service life of the oil-fume purifier but also reduces energy consumption and operating costs, thus providing strong support for the green development of the catering industry. Therefore, the tungsten needle plays an irreplaceable role in honeycomb-electric-field oil-fume purifiers.
