Problem - When deodorizing and refining oil in a deodorizing tower connected to a vacuum device, it is necessary to introduce high-temperature steam (about 120° C.) into the deodorizing tower. In this case, conventionally, the steam was directly introduced from a boiler, released into the oil, and fatty acids or volatile components, which were odor components, in the oil were absorbed and discharged in a vacuum.

いる。In the diagram, the upper and lower ends of the deodorizing tower 10 are connected to a vacuum device 12 and a product unloading device 14, which are not shown and are known per se. Inside the deodorizing tower 10, deodorizing trays 18a, . . . , 18n are arranged, which are supplied with deodorizing steam sent from the steam pipe 16 and perform a deodorizing action using the deodorizing steam.

ポンプ２８を介して放出されている。The steam pipe 16 is connected via a pipe 20 to an evaporator 22 which operates under reduced pressure. A heat exchanger 21 is preferably interposed in the limb tube 20 . High-temperature (approximately 70 to 95°C) waste liquid generated in the factory is introduced into the evaporator 22 through a pipe 24, and is evaporated at a low temperature in the evaporator 22, which operates under reduced pressure, and then reduced to a lower temperature. In this state, low-temperature water is discharged from the pipe 26 via a pump 28.

され脱臭が完成する。As mentioned above, the evaporator 22 is connected to the deodorizing tower 1 via the pipe 20.16.
0 and to the vacuum device 12, the low temperature vapor formed by low temperature evaporation of the high temperature water fed to the evaporator 22 operating under reduced pressure can enter the deodorization tower 10 at any desired time. Due to the low pressure inside the deodorizing tower 10, the steam that has entered the deodorizing tower 10 undergoes low-temperature evaporation while passing through the preheating tray 18a,
Deodorizing tray 1 such as heating tray 18b and cooling tray 18n
Enter the oil within 8a to 18n. The oil in the deodorizing trays other than the low-temperature cooling tray in the lower part of the deodorizing tower is always maintained at about 250°C, so the low-temperature evaporated steam exchanges heat with the oil. Approximately 250
rises to ℃. As a result, odor components such as fatty acids are vacuum-sucked by the low-temperature steam formed from the high-temperature water, and deodorization is completed, as in the conventional case.
従って本装置によれば、蒸気管１６へ高温蒸気を送るボ
イラーは不要となる。Therefore, according to this device, a boiler that sends high-temperature steam to the steam pipe 16 is not necessary.

Only the insufficient amount of steam sucked into the evaporator 22 is supplied from high-temperature waste water to the evaporator 22.

用低温蒸気の温度上昇を図ることも出来る。Furthermore, in order to maintain a constant water temperature in the evaporator 22 so as to perform deodorizing work of a constant quality, it is also possible to exchange heat between the water in the evaporator and high-temperature factory wastewater using a heat exchanger 30. Furthermore,
The high-temperature exhaust gas coming out of the dedicated boiler 19 of the heating tray 18b is introduced into the heat exchanger 21 in the pipe 20 through the pipe 23, thereby increasing the temperature of the low-temperature deodorizing steam supplied from the evaporator 22 to the deodorizing tower 10. It is also possible to plan.
正月しυ例呈−
本発明では、脱臭作用をする蒸気を工場排水より獲得し
ているためこれまでの脱臭用蒸気発生用の専用ボイラー
は不用となった。New Year's Day Example - In the present invention, the deodorizing steam is obtained from factory wastewater, so the conventional dedicated boiler for generating deodorizing steam is no longer necessary.
工場排水蒸気は７０〜９５℃程度であるが真空下で使用
されるために、低温蒸発が生じ、また脱臭作業中の油に
よりこれまでの脱臭蒸気温度まで容易に上昇する。この
ため脱臭効率を落すことはない。Factory wastewater steam has a temperature of about 70 to 95°C, but since it is used under vacuum, low-temperature evaporation occurs, and the oil during deodorization easily raises the temperature to the conventional deodorizing steam temperature. Therefore, the deodorizing efficiency is not reduced.
蒸発器とポンプとの間で蒸気を循環することにより所望
の脱臭蒸気を得ることができる。By circulating the steam between the evaporator and the pump, the desired deodorized steam can be obtained.
加熱トレー専用ボイラーの高温排ガスにより脱臭蒸気の
蒸気温度を高くすることができる。The temperature of the deodorized steam can be raised using the high-temperature exhaust gas from the boiler dedicated to the heating tray.
