Hereinafter, a condenser according to a first embodiment of the present invention will be described with reference to FIG. FIG. 1 is a schematic cross-sectional view showing a condenser according to a first embodiment of the present invention. FIG. 2 shows a gas cooler of a condenser according to the first embodiment of the present invention, in which (a) is a schematic top sectional view and (b) is a schematic transverse sectional view.

出された蒸気を水平方向に取り込む軸流排気型を適用することができる。 As shown in FIG. 1, the condenser 1 includes a condenser main body 2, an exhaust duct 3, and a gas cooler 4. The condenser 1 is a direct contact condenser for geothermal heat, and an axial exhaust type that takes in steam discharged from the rear of the turbine in the horizontal direction can be applied.

Vapor (mixed gas) exhausted from (not shown) is introduced into the condenser main body 2. The condenser main body 2 has a steam condensing device (not shown) such as a spray or a tray, forms a hot well in the lower part, and discharges the condensed steam from the bottom.

排出する。 As shown in FIG. 2, the gas cooler 4 has a gas cooler outlet 5, a flow path forming member 6, and a spray nozzle 7 as a cooling device. In the gas cooler 4, one end of a long cylindrical shape is connected to a surface on the side opposite to the exhaust duct 3 in the side surface of the condenser main body 2, and a flow path is extended in a direction opposite to the exhaust duct 3. A gas cooler outlet 5 is provided at the end of the flow path of the gas cooler 4 to discharge the cooled gas.

だけでなく、ガスクーラ４の筐体自体を流れ方向下流につれて狭める形としてもよい。 The flow path of the gas cooler 4 is formed by the flow path forming member 6 so that the cross-sectional area of the flow path becomes smaller in the downstream direction of the mixed gas flow. Alternatively, not only the flow path is narrowed by the flow path forming member 6, but the casing of the gas cooler 4 itself may be narrowed toward the downstream in the flow direction.

スプレーノズル７は、ガスクーラ４の流路内部の上面に設けられ、ガスクーラ４の流路
内部に冷却水を噴霧する冷却装置である。 The spray nozzle 7 is a cooling device that is provided on the upper surface inside the flow path of the gas cooler 4 and sprays cooling water inside the flow path of the gas cooler 4.

気は落下して、復水器本体胴２下部のホットウエルより底部より外部に排出される。 During the operation of the geothermal power plant, the mixed gas discharged from the turbine is introduced into the condenser main body 2 from the exhaust duct 3. In the condenser main body 2, in the spray method, the cooling water sprayed by the spray is brought into contact with the mixed gas to condense the vapor, and in the tray method, the cooling water falling from the perforated plate tray is brought into contact with the mixed gas. Condenses the vapor. The condensed steam falls and is discharged from the bottom to the outside through the hot well at the bottom of the condenser main body 2.

が不十分になるおそれがある。 The mixed gas cooled in the condenser main body 2 is introduced into the gas cooler 4. Here, in general, since the mixed gas of the vapor and the non-condensable gas is cooled to reduce the volume, the conventional gas cooler having a constant flow path area has a low flow velocity in the vicinity of the gas cooler outlet. When the flow rate is small, the stirring effect of the mixed gas and the cooling water from the spray nozzle 7 is lowered, and there is a possibility that the cooling becomes insufficient.

そこで本実施形態では、ガスクーラ出口５に向かって蒸気流路面積が狭くすることで、
流速が小さくなることを抑制して混合気体をガスクーラ出口５まで流すことができ、攪拌
効果の低下による冷却効果の低下を抑制することができる。 Therefore, in this embodiment, by reducing the steam flow path area toward the gas cooler outlet 5,
It is possible to flow the mixed gas to the gas cooler outlet 5 while suppressing the flow rate from being reduced, and to suppress a decrease in the cooling effect due to a decrease in the stirring effect.

効果が低くなり、冷却が不十分になるおそれがある。そこで本実施形態では、混合気体を
ガスクーラ出口５に向かって蛇行して流すことによって流路を長くし、蛇行しない場合と
比較して冷却水との接触時間を長くする。 Since the mixed gas of the vapor and the non-condensable gas is cooled and the volume is reduced, the flow velocity is reduced toward the gas cooler outlet 5, and the stirring effect with the cooling water from the tray 9 by the mixed gas is reduced. Cooling may be insufficient. Therefore, in the present embodiment, the mixed gas is caused to meander and flow toward the gas cooler outlet 5 to lengthen the flow path, and the contact time with the cooling water is lengthened as compared with the case where the gas does not meander.

本実施形態によれば、混合気体流路にバッフル８を設置して流れを蛇行させることによ

Hereinafter, a condenser according to a third embodiment of the present invention will be described with reference to FIG. FIG. 4 shows the gas cooler of the condenser according to the first embodiment of the present invention, (a) is a schematic top sectional view,
(B) is a schematic cross-sectional view. In this embodiment, in the flow path of the gas cooler 4, the baffles 8 are alternately installed perpendicular to the flow direction of the mixed gas, and the installation interval of the baffles 8 is narrowed in the downstream direction of the flow.

水の攪拌効果による冷却効果も持続させることができる。 According to the present embodiment, the flow path can be lengthened by meandering the mixed gas by the baffle 8 and the contact time with the cooling water can be lengthened. Furthermore, by shortening the space | interval of the baffle 8 toward the flow direction downstream, the fall of the flow velocity of mixed gas is suppressed and the cooling effect by the stirring effect of mixed gas and cooling water can also be maintained.

(B) is a schematic cross-sectional view. In the present embodiment, the flow path forming member 6 is configured to reduce the flow path area of the steam toward the downstream side in the flow direction of the mixed gas of the gas cooler 4 and to alternately install the baffles 8 perpendicular to the flow direction.

Further, by reducing the cross-sectional area of the flow path toward the downstream in the flow direction by the flow path forming member 6, the decrease in the flow velocity of the mixed gas is suppressed, and the cooling effect due to the stirring effect of the mixed gas and cooling water can be maintained. it can.
