The invention discloses a microwave and steam hybrid heating roller table drying kiln. The drying kiln comprises a roller table which is arranged on a frame and a roller table transmission system (18), wherein a kiln-entering microwave suppression section (1), a dehumidifying section furnace body (2), a steam heating and temperature raising section furnace body (3), a steam and microwave hybrid heating and drying section furnace body (4), a microwave heating and drying section furnace body (5), a cooling section furnace body (6), a heat pumping section furnace body (7) and a kiln-leaving microwave suppression section (8) which are provided with the roller table and are sequentially abutted are arranged on the frame; the dehumidifying section furnace body (2) and the steam heating and temperature raising section furnace body (3) are abutted with a dehumidifying and air exhausting system (10); and the heat pumping section furnace body (7) is abutted with a heat pumping and air exhausting system (12). In the microwave and steam hybrid heating roller table drying kiln, microwaves and steam are used for heating in a mixed manner, so that the advantages of steam heating and microwave heating are combined; and based on the advantages of microwave and steam hybrid heating, the microwave and steam hybrid heating roller table drying kiln has the advantages of low heating temperature, high response speed, high material processing quality, high heating match performance, energy conservation, emission reduction and high energy efficiency.
Description
technical field [0001] The invention relates to a drying kiln, in particular to a microwave and steam mixed heating roller table drying kiln. Background technique [0002] Roller table drying kiln is a large-scale drying kiln with continuous feeding and continuous discharging. It has high production efficiency and is widely used in drying kilns in ceramics, chemical industry, metallurgy, battery materials and other industries. The current heating methods are resistance heating, gas heating, oil heating, kiln waste heat and microwave heating. The traditional roller drying kiln generally has a relatively high drying temperature, slow reaction speed, and low quality of the dried material; the drying heating temperature of the material is high, and the drying speed is slow. Microwave heating is different from traditional heating in mechanism of action. In the experiment, the same material is heated and compared. The drying temperature of microwave heating material is generally ...
