本発明は、熱風循環径路を通じて使用温度に加熱された
熱風を乾燥炉内に循環供給する乾燥装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drying device that circulates and supplies hot air heated to a working temperature through a hot air circulation path into a drying oven.
この種の乾燥装置は、乾燥炉の各ゾーンごとに設けられ

加熱された熱風を熱風循環ファンで乾燥炉内に循環供給
するように成されているのが一般的である。This type of drying equipment has a plurality of hot air circulation paths provided in each zone of the drying oven, each equipped with a hot air circulation fan and a hot air heating burner, and the hot air heated to a predetermined operating temperature by the burner. Generally, hot air is circulated and supplied into the drying oven using a hot air circulation fan.

６２−２５４８２６号公報参照）。By the way, in recent years, energy has been saved by effectively utilizing the waste heat of the deodorizing gas obtained by burning and decomposing the malodorous components in the exhaust gas that is exhausted from the drying oven and sent to a direct combustion type or catalytic combustion type deodorizing device. For example, fresh outside air introduced into the drying oven is indirectly heated by heat exchange with the deodorizing gas, and the hot air circulation path is equipped with a hot air circulation fan and a hot air heating burner. (see Japanese Patent Laid-Open No. 63-42773), or the heat medium oil heated by heat exchange with the deodorizing gas is interposed in the hot air circulation path together with a hot air circulation fan or a hot air heating burner. Attempts have been made to feed it into a heat exchanger (see Japanese Patent Laid-Open No. 62-254826).
しかし、これらは何れも、乾燥炉内に循環供給される熱
風を脱臭ガスの廃熱のみによって使用温度に加熱するも
のではなく、あくまでも脱臭ガスの廃熱を補助的に利用
するに過ぎなかった。However, none of these methods heats the hot air circulated into the drying oven to a working temperature using only the waste heat of the deodorizing gas, but only uses the waste heat of the deodorizing gas as an auxiliary method.
このため、各熱風循環径路には従前どおり熱風加熱用バ
ーナが介装され、当該バーナの燃焼量を個々に調節して
乾燥炉の各ゾーンごとに供給される熱風の使用温度を制
御することとしている。For this reason, each hot air circulation path is equipped with a hot air heating burner as before, and the combustion amount of the burner is individually adjusted to control the operating temperature of the hot air supplied to each zone of the drying oven. There is.

風の温度コントロールシステムが煩雑になるという欠点
があった。Therefore, the drying equipment must be equipped with a large number of burners, such as hot air heating burners installed in each hot air circulation path and burners for the deodorizing equipment, which increases equipment costs and increases the number of burners installed in each burner. The drawback was that the temperature control system for the heated air was complicated.

システムを容易にすることを目的とする。Therefore, the present invention has developed a technical technique that eliminates the hot air heating burner installed in each hot air circulation path, and heats the hot air circulated and supplied into the drying oven only with the burner provided in the deodorizing device. The purpose of the present invention is to solve this problem, significantly reduce burner equipment costs, and facilitate the hot air temperature control system.
