Description

technical field [0001] The invention relates to a drying device for medium wave, short wave and jet combined heating. Background technique [0002] China is one of the countries with the lowest per capita energy reserves in the world. Per capita energy consumption is only half of the world average. But on the other hand, China's current energy utilization rate is only about 30%, which is about 10 percentage points lower than that of developed countries. The energy consumption of output value is more than 2 times higher than the world's average level, and more than 10 times that of Germany, making it one of the countries with the highest energy consumption of output value in the world. Therefore, "saving energy and protecting the environment" has become the top priority of government work. At present, energy saving and consumption reduction has become a major issue related to the sustainable development of social economy such as national economic security, international ma...

Problems solved by technology

At present, the traditional drying methods mainly include hot air convection heating, traditional infrared heating and other methods. Hot air convection heating has a great influence on the uniformity of heat in the furnace due to its large thermal inertia, long heating time, and furnace design structure, which is prone to temperature differences. , resulting in poor coating quality, prone to pinhole effect, foaming, its own equipment is huge, covers a large area, convection requires a large amount of circulating air flow, it is easy to cause dust in the furnace, causing secondary pollution of the paint surface, so using this Drying in this way not only has low work efficiency and poor working environment, but more importantly, it is dangerous
