At present in the papermaking industry domestic and foreign large and small papermaking manufacturers are still widely used is the traditional oil heating and steam heating paper dryer. In the production process of many years, the traditional paper dryer equipment exposed many deficiencies, low energy efficiency, equipment investment, pollution of the environment, frequent production accidents. With the aggravation of the international energy shortage in recent years and the enhancement of people's awareness of environmental protection, various industrial sectors are constantly transforming old equipment and developing new energy-saving and efficient equipment.
As a large energy user in papermaking production line, the reform of papermaking heating dryer needs to fundamentally change the heating mode with hot oil and superheated steam as heating medium, so as to find a simple, convenient and pollution-free alternative.
At present, the heating infrared radiation, hot air convection and surface contact conduction of heat conducting oil drum are the main ways of shaping the blanket. Each style has its own advantages and disadvantages. With the increasing energy stress, coal, oil, electricity and other energy will rise has become the current social consensus. With the improvement of papermaking technology, the quality requirement of papermaking blanket is getting higher and higher. There are many problems such as high energy consumption, low degree of automation, and unsatisfactory effect of the former design. Therefore, it is urgent to apply one or more new and more energy-saving and effective production heating methods to industrial production.
Advantages of qi jiaxin electromagnetic heating roller in hunan:
1. The electromagnetic heating roller has fast heating speed and high thermal efficiency. The electromagnetic heating roller is the heating of metal roller itself, which reduces the heat loss in heat transfer, and the heat conversion efficiency is more than 95%;
2. The temperature difference of roll surface is small, up to ±1℃, and the temperature control precision is high, up to ±0.1℃;
3. Flexible temperature adjustment, can adjust temperature uniformity and temperature distribution temperature according to the temperature curve required by the product;
4. Good temperature stability, high production efficiency, no defective products, can improve the production line speed;
5. Intelligent operation, simply set the temperature of the instrument without other tedious adjustment procedures;
6. Energy saving and environmental protection. Compared with oil heating roller and resistance wire heating roller, the energy saving effect of electromagnetic heating roller can reach more than 50%; No oil pollution in the workshop, no harm to the health of employees, safe and reliable use process;
7. Electrical components are free of mechanical friction and loss, with low maintenance cost and few faults. The heating ring inside the heating roller and the external controller are components, and the installation is quick, convenient, energy-saving and safe.
