本発明はスプレー１−″ライヤーにおりるガス置換方法
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for replacing gas in a spray 1-'' ryer.
従来スプレードライヤ〜の乾燥室１内の先住ガスをＮ２
ガスなどの置換ガスに置換するには次のような方法がと
られている。以下置換ガスる。 ′
■ ガス流による押し出し
■ 減圧法
■ 液体注入置換法
■の方法は、第１図においてＮ２ガスをＮ２ガス供給管
２から圧入しで、空気を押し出し置換する方法である。The native gas in the drying chamber 1 of the conventional spray dryer is replaced with N2.
The following methods are used to replace the gas with a replacement gas such as gas. The following replacement gas is used. ' ■ Extrusion by gas flow ■ Decompression method ■ Liquid injection displacement method ■ In FIG. 1, N2 gas is injected through the N2 gas supply pipe 2, and air is pushed out and replaced.
この方法では乾燥室内でＮ２ ガスと空気が混合しなが
ら徐々に空気が置換されてゆき占有しているスペースが
大きい場合及びＮ２ガスの純度を上げるためには置換す
るのに大量のＮ２ガスを要するこさになり、経済的でな
い問題点を有する。 ′
■の方法は排出管４などから空気を吸引し、乾燥室Ｉ内
を減圧し、この減圧分に対応してＮ２ガスを置換する方
法である。In this method, the air is gradually replaced while N2 gas and air are mixed in the drying chamber, and if the space occupied is large, and in order to increase the purity of the N2 gas, a large amount of N2 gas is required for replacement. It becomes small and has problems that are not economical. ' Method (2) is a method in which air is sucked through the exhaust pipe 4, etc., the pressure inside the drying chamber I is reduced, and N2 gas is replaced in proportion to the reduced pressure.
しかしこの方法は■の方法と同様Ｎ２ガスと空気が混合
しては置換されでゆき、空気の占めるスペースが大きい
場合及びＮ２ガスの純度を上げるためにはＮ２ガスを大
量に必要とするだけでなく、乾燥室１の耐圧性能を要求
される難点がある。However, in this method, like method (2), N2 gas and air are mixed and replaced, and if the space occupied by air is large or to increase the purity of N2 gas, a large amount of N2 gas is only required. However, there is a drawback in that the drying chamber 1 is required to have high pressure resistance.
また■の方法は液体を乾燥室１内に注入し。Also, in method (■), a liquid is injected into the drying chamber 1.
その注入量分たーけ、空気を追い出す方法である。This is a method of expelling air according to the amount of injection.
この方法は残留する空気の量は少ないが、乾燥室１の耐
圧性能が要求されるだけでなく、注入液を取り出した後
、乾燥させる手間がか＼る。Although this method leaves a small amount of residual air, it not only requires pressure resistance of the drying chamber 1, but also requires time and effort to dry the injected liquid after taking it out.
本発明は以上のような従来のガス置換方法を改良するこ
とを目的とする。すなわち、本発明は以下述べるように
、乾燥室１内に気密な袋５を挿入してふくらませた後１
袋５と乾燥室１の間隙について空気をＮ２ガスに置換す
る方法である。The present invention aims to improve the conventional gas replacement method as described above. That is, as described below, in the present invention, after inserting an airtight bag 5 into a drying chamber 1 and inflating it,
This method replaces the air in the gap between the bag 5 and the drying chamber 1 with N2 gas.
本発明はこのような構成をとることにより、先住ガス空
気の占めるスペースを小さくシ、この小さいスペースに
ついてガス置換することにより少ないＮ２ガスで完全な
ガス置換を可能としようとするものである。By employing such a configuration, the present invention attempts to reduce the space occupied by the native gas air, and by performing gas replacement in this small space, it is possible to perform complete gas replacement with less N2 gas.
（実施例の説明） 以下本発明方法の実施例について説明する。(Explanation of Examples) Examples of the method of the present invention will be described below.
