れている。Heat exchange equipment using heat pipes, which exchanges heat through phase transformation due to evaporation and condensation of the working fluid, is generally used to recover sensible heat from factory exhaust gas, waste water, etc.; Depending on the conditions of the working fluid, it may be necessary to separate the evaporating section and condensing section of the working fluid and place them at separate locations, and in such cases a separate heat exchanger is used.

) are connected with a heat insulating pipe (5) to form a circulation circuit, a working fluid (6) is charged into the circuit, and this is circulated in the direction of the arrow to generate heated fluid (A) in the evaporator (1). ) to evaporate the working fluid (6), the generated steam is introduced into the condensing part (2) through the pipe (4), and is cooled by the heated fluid (B) to condense the steam, and then into the tank (3). The heating fluid (A) and the fluid to be heated (B) exchange heat by flowing downward. The working fluid (6) can be circulated naturally depending on the height relationship between the evaporating section (1) and the condensing section (1), or by installing a pump (7) in the piping (5) as shown in the figure.

になる。This device applies the principle of a heat pipe, and even if the evaporating section and condensing section are separated, the working fluid and steam can circulate well, and it exhibits excellent heat exchange characteristics. However, when used for actual waste heat recovery, etc., air, etc. remains in the circuit during operation, and waste condensable gas, such as water and iron, is generated due to the reaction between the working fluid and equipment materials during operation. may generate hydrogen, and if the circuit is operated under negative pressure,
Air is sucked in from the flange, etc. If such non-condensable gases exist in the circuit, they not only obstruct the movement of the working fluid and steam, but also remain in the condensing section, deteriorating the heat exchange characteristics. That is, when evaporation in the evaporation section and condensation in the condensation section are repeated, non-condensable gas accumulates on the downstream side of the vapor flow in the condensation section.
This will reduce the condensation area of the condensation section and deteriorate the heat exchange characteristics.
従って凝縮部内の非凝縮性ガスの滞留を速やかに検知し
、これを適当なタイミングで排出する必要がある。Therefore, it is necessary to quickly detect the accumulation of non-condensable gas in the condensing section and discharge it at an appropriate timing.

下流側（図では下部へラダーとその下方）に滞留する。Generally, the condensing section has both upper and lower headers (2
A one-digit heat transfer tube (2c) is installed between a) and (2b), and the steam introduced from the pipe (4) enters the heat transfer tube (2C) through the header (2a) and is heated by the heated fluid (B). It is cooled to form condensed droplets (8) on the inner wall of the heat transfer tube (2C),
It flows down the wall surface, passes through the lower header (2b), and flows into the tank (3), and the non-condensable gas (9) is retained on the downstream side of the steam flow (in the figure, toward the bottom of the ladder and below it).

む欠点があった。Further, although not shown in the figure, in the case where steam is introduced from below the condensing part, the steam remains on the downstream side of the flow, that is, in the upper part of the condensing part. In order to exhaust this accumulated non-condensable gas,
Conventionally, a pipe (10) connects the lower header (2b) of the condensing section (2) and the tank (3) below the flow of steam, as shown in the figure.
A discharge pipe (11) is attached to the pipe, and the non-condensable gas (9) is discharged by manually opening and closing a discharge valve (12) provided at the tip of the pipe at appropriate intervals. However, since there is no means to detect the accumulation of non-condensable gas5-, it is not only difficult to maintain the condensing section in a good condition, but also non-condensable gas may be sucked in if the pressure inside the circuit is negative. There were drawbacks.

置を自動的に作動させることを特徴とするものである。In view of this, as a result of various studies, the present invention found that when non-condensable gas stagnates in the condensing section, temperatures occur on the upstream and downstream sides of the flow of steam in the condensing section. We have developed a method for discharging non-condensable gas from a separate type heat exchanger that always shows good heat exchange characteristics by automatically discharging non-condensable gas that accumulates in the evaporating section and condensing section. A circulating circuit is formed by connecting these with insulated piping, and a working fluid is charged and circulated in the circuit to exchange heat by phase transformation of the working fluid. In this method, a discharge pipe is provided on the downstream side of the flow of steam in the condensing section or on the downstream piping. It is characterized by detecting the temperature difference and automatically operating the discharge device based on the temperature difference.

結果、蒸気の流れの上流側と下流側で温度差を生ずる。That is, as a result of detailed observation of the behavior of steam, condensate, and non-condensable gas in the condensing section 6 of a separate heat exchanger, the present invention found that the steam introduced into the condensing section is condensed by the heated fluid and flows down. , the temperature distribution inside the condensing section is almost equal. However, when non-condensable gas remains in the heat transfer tube, the flow of steam is impaired and the amount of condensation by the heated fluid is reduced. Moreover, as a result of the heat transfer tube being cooled by the fluid to be heated, a temperature difference occurs between the upstream side and the downstream side of the steam flow.

動的排出するものである。Furthermore, in order to make full use of the heat transfer area of the heat exchanger tube, it is necessary to detect the temperature at the upstream and downstream sides of the steam rather than inside the heat exchanger tube. In addition, as a result of the study, it was found that a discharge device was installed in the discharge pipe installed on the downstream side of the steam flow, or on the downstream side.
The non-condensable gas stagnant in the condensing section is automatically discharged by detecting the temperature difference and activating the discharge device based on the temperature difference.

ことが望ましい。The discharge device is equipped with an automatic opening/closing valve or/and a forced discharge pump in the discharge pipe, and it is desirable to operate it when the temperature difference is 2°C or more, and when the temperature difference is below 2°C, the non-condensable gas and working fluid are discharged. may be emitted. Further, even if the temperature difference becomes 2° C. or more, it is desirable that the discharge device is not activated immediately, but activated after a certain period of time. This is because even if only the non-condensable gas in some of the heat transfer tubes is discharged, the temperature difference continues due to the non-condensable gas in other tubes, causing so-called uneven flow suction in which the working fluid is discharged. This is to prevent this. In addition, when discharging non-condensable gas, it is desirable to detect the pressure in the circuit, open an automatic shut-off valve if the pressure is positive in the circuit, and operate a forced discharge pump if the pressure is negative. .

In addition, a known temperature detector such as a thermal lightning pair or a resistance temperature detector may be used to detect the concentration, and a temperature difference controller may be used to detect the temperature difference.
