Abstract

The invention discloses a hot air drying furnace. The hot air drying furnace comprises a hot air furnace, a feeding drum, rotary drying drums and a discharging port. Materials enter the rotary drying drums to be heated through the feeding drum, a dehumidifier is arranged at a feeding port of each rotary drying drum, a waste heat recovery tank is arranged at the top of each dehumidifier, each rotary drying drum is provided with a balance hot air chamber, a discharging drum is arranged at the tail end of the rotary drying drums, and the upper end and the lower end of the discharging drum are provided with a waste gas outlet and the discharging port respectively. The hot air drying furnace has advantages of simple structure, low cost, high drying quality, low energy consumption and high heat efficiency.

Description

technical field [0001] The invention relates to a drying furnace, in particular to a continuous hot air drying furnace. Background technique [0002] In the preparation process of tungsten oxide, ammonium paratungstate is sent as a raw material into a well-sealed container for heating to decompose it into tungsten trioxide, ammonia gas and water vapor; the decomposed ammonia gas is further decomposed into nitrogen gas and hydrogen gas; in the container , using hydrogen to reduce tungsten trioxide to blue tungsten oxide, and hydrogen combines with water to form water, so the resulting product generally contains crystal water and needs to be dried. A drying furnace is required for drying. The existing drying furnaces have high energy consumption, poor drying quality, large investment and low thermal efficiency. Contents of the invention [0003] The technical problem solved by the present invention is to provide a hot air drying furnace to solve the above-mentioned shortcom...
