て飽和させるものである。Cage [Conventional technology] Figure 1 shows the conventional technology based on the /\Ipass method.
The odor device is shown, and eight throttle mechanisms 02 are installed in the gas conduit 01.
At the same time as installing the bypass pipe 03
Take the odorant tank 04 into the bypass tank 03 of 1.
The odorizing agent is evaporated and saturated in the gas passing through the bypass pipe 03.
従来のバイパス式付臭方法(装置)は以上の如き構成の
ため、バイパス管内を通過するガスの温度及び圧力変動

しながらバイパス管03内を通過するガス量を変化させ
て濃度が規定の範囲内に収まるように調整している。Since the conventional bypass type odorization method (device) has the above-described configuration, it has a drawback that the odor concentration changes when there are fluctuations in the temperature and pressure of the gas passing through the bypass pipe. Therefore, in the past, a manual valve 05 was installed in the bypass pipe 03, and the concentration was kept within a specified range by operating the manual valve 05 relying on experience and intuition to change the amount of gas passing through the bypass pipe 03. It has been adjusted to fit.
しかし、上記の方法では、経験者でないと調整出来ない
ことと、温度変化や圧力変化が大きい設備ではバルブの
操作が頻繁となり、現実的な対応が不可能である。そこ
で、他の付臭装置に比し多くの利点を有する前記従来方
式ではあるが、採用は見送られている。However, with the above method, only an experienced person can make adjustments, and in equipment where temperature and pressure changes are large, the valves must be operated frequently, making it impossible to handle them realistically. Therefore, although the conventional method has many advantages over other odorizers, its adoption has been postponed.

度を一定に維持するものである。In order to achieve the above object, the present invention detects the pressure and temperature of the gas passing through the bypass pipe (line), calculates the correction value using the following formula based on the detected value, and calculates the correction value. Based on this correction value, the flow rate control valve installed in the bypass pipe is automatically controlled to maintain a constant odor concentration while controlling the flow rate.
