の伝熱を促進する装置に関する。Detailed Description of the Invention (Industrial Application Field) The present invention is installed in a condensing heat exchanger that performs heat exchange by discharging the latent heat of heat medium vapor into a heat transfer tube, The present invention relates to a device for promoting heat transfer in the condensing heat exchanger, in which a force is applied and condensate is discharged by this force.
(従来の技術)
第2図、第3図及び第4図を参照して、公知の
電場による熱伝達促進装置を説明する。(Prior Art) A known electric field-based heat transfer promoting device will be described with reference to FIGS. 2, 3, and 4.
まず、第2図を参照して、凝縮熱交換器の概略
を説明する。 First, the outline of the condensing heat exchanger will be explained with reference to FIG.
1は、凝縮熱交換器である。ケーシング2内に
複数の伝熱管3が縦置に設けられている。 1 is a condensing heat exchanger. A plurality of heat exchanger tubes 3 are provided vertically within the casing 2.
ケーシング2の下部にある冷却水導入口4から
冷却水が導入され、伝熱管3内を上昇する。一
方、蒸気導入口からは、フロンなどの熱媒体の蒸
気が、ケーシング2内に導入される。 Cooling water is introduced from a cooling water inlet 4 at the bottom of the casing 2 and rises inside the heat exchanger tubes 3. On the other hand, steam of a heat medium such as fluorocarbon is introduced into the casing 2 from the steam inlet.
冷却水が流れる伝熱管3の表面に熱媒体の蒸気
が潜熱を放出して凝縮付着する。伝熱管3を上昇
する間に受熱して昇温した冷却水は、冷却水導出
口6から導出される。熱媒体の凝縮液は伝熱管3
を伝つて重力によつて降下し、ケーシング2の下
部にある凝縮液排出口7から排出される。 The steam of the heat medium emits latent heat and condenses and adheres to the surface of the heat transfer tube 3 through which the cooling water flows. The cooling water whose temperature has increased by receiving heat while moving up the heat exchanger tube 3 is led out from the cooling water outlet 6 . The condensed liquid of the heat medium is transferred to the heat transfer tube 3.
The condensate is then lowered by gravity and is discharged from the condensate outlet 7 at the bottom of the casing 2.
ところが、伝熱管3の表面には下方に流れる凝
縮液の液膜が生じ、この液膜が新たな蒸気の凝縮
を阻害していた。つまり、伝熱管3の表面に付着
した凝縮液の液膜は薄ければ薄い程、新しい蒸気

で伝熱管3から引き出して除去し、伝熱管3の表
面の液膜を薄くして凝縮を促進させる装置であ
る。 However, a liquid film of the condensate flowing downward was formed on the surface of the heat exchanger tube 3, and this liquid film inhibited the condensation of new vapor. In other words, the thinner the liquid film of the condensate adhering to the surface of the heat exchanger tube 3 is, the more desirable it is for new vapor to condense and adhere. Therefore, the heat transfer promoting device described below is a device that draws and removes the condensed liquid from the heat exchanger tubes 3 using the action force of an electric field, thins the liquid film on the surface of the heat exchanger tubes 3, and promotes condensation.

伸張する支持体10により支持され設けられてい

縦方向に伸張する排液体12に接続されている。 Referring to FIG. 3, a wire electrode 9 is spirally wound in a single layer around a heat exchanger tube 3 made of a conductor such as a metal at a distance from the surface 8 of the heat exchanger tube 3, and extends in the vertical direction. It is supported and provided by a support body 10. The terminal end 11 of the wire electrode 9 is connected to a waste liquid 12 extending longitudinally away from the heat exchanger tube 3 .

して、前記凝縮液排出口7からケーシング2外に
排出される。 When the heat exchanger tube 3 is used as one electrode and the wire electrode 9 is used as the other electrode, and a high voltage is applied between the two, the condensate flows from the surface 8 of the heat exchanger tube 3 to the wire electrode 9 as shown in FIG. being pulled towards someone. The condensate flows down along the helical line electrode 9, and the centrifugal force of the flowing condensate overcomes the force due to the electric field and is connected to the drain liquid 12, causing it to flow downward along the drain liquid 12. The condensate is then discharged to the outside of the casing 2 from the condensate discharge port 7.
(発明が解決しようとする課題)
上記、従来の凝縮熱交換器における熱伝達促進
装置では、1重の線電極9を多段に設置して用い
ていた。(Problems to be Solved by the Invention) In the above-described conventional heat transfer promoting device for a condensing heat exchanger, single wire electrodes 9 were installed in multiple stages.
凝縮液の排出をできるだけ多くするためには、
螺旋状の線電極9をできるだけ密に巻回するほう

回したものを実験してみた。 In order to drain as much condensate as possible,
It is more effective to wind the spiral wire electrode 9 as tightly as possible. Therefore, the spiral wire electrode 9 shown in the figure
An experiment was conducted in which the tubes were wound in multiple stages around the heat exchanger tube 3, with the other configurations unchanged.
ところが、2重螺旋の線電極9では、上側の線
電極9で殆どの凝縮液を引き出してしまうため、
下側の線電極9に引き出された凝縮液が僅かとな

9から排液体12に移行しないのである。 However, with the double spiral wire electrode 9, most of the condensate is drawn out by the upper wire electrode 9.
A small amount of condensate is drawn out to the lower wire electrode 9. Therefore, the centrifugal force of the condensate flowing down the wire electrode 9 due to gravity does not exceed the force exerted by the electric field, and remains attached to the wire electrode 9 due to the force exerted by the electric field. That is, the condensed liquid does not transfer from the wire electrode 9 to the drained liquid 12.
本発明は上記公知の電場による伝熱促進装置を
改良したものである。 The present invention is an improvement on the above-mentioned known electric field-based heat transfer accelerator.
本発明の目的は、凝縮液の引き出し量が従来よ

Cooling water flows through the heat exchanger tube 3, and vapor of a heat medium such as fluorocarbon releases latent heat to the heat exchanger tube 3, and condenses and adheres to the surface of the tube. On the other hand, the cooling water receives heat and rises in temperature.

Therefore, the heat transfer promoting device of the present invention for removing the condensate on the surface 8 of the heat transfer tube 3 using an electric field is provided as follows.

Heavily spirally wound wire electrodes 9a, 9b are supported by a support 10 extending in the longitudinal direction. The wire electrodes 9a, 9b are provided in multiple sets in multiple stages from the upper end to the lower end of the heat exchanger tube 3. In FIG. 1, two sets of wire electrodes, upper stage X and lower stage Y, are shown to simplify the explanation.
The invention is not limited to this example. Moreover, the cross-sectional shape of the heat exchanger tube 3 is not limited to a circle.

A high voltage is applied between them with 9b as the other electrode, and the condensate on the surface 8 of the heat exchanger tube 3 is transferred to the wire electrodes 9a, 9.
It is pulled out to the b side. In the present invention, the wire electrode 9
The reason why a and 9b are wound twice is to draw out a larger amount of condensate than a single wire electrode.
伝熱管3と線電極9a,9bの接触してシヨー

a,9bの間隔を保持する絶縁材料から成るスペ
ーサを設けてもよい。 In order to prevent the heat exchanger tube 3 and the wire electrodes 9a and 9b from coming into contact and shooting, the heat exchanger tube 3 and the wire electrodes 9a and 9b are
A spacer made of an insulating material may be provided to maintain the distance a, 9b.

線電極9a,9bの螺旋の傾斜が、下方にいくに
従つて急角度に形成され、凝縮液の加速を増加し
遠心力を増すようにしてある。 The drawn condensate is transferred to spiral wire electrodes 9a, 9.
It flows downward along b, but in this example,
The spiral slope of the wire electrodes 9a, 9b is formed at a steeper angle as it goes downward, increasing the acceleration of the condensate and increasing the centrifugal force.

の始端に連絡するように構成してもよい。 However, since the lower line electrode 9b draws out less amount of condensate than the upper line electrode 9a, the centrifugal force when flowing down the line electrode 9b is not large enough to reach the drained liquid 12, and the line It moves while adhering to both the electrode 9b and the surface 8 of the heat exchanger tube 3 (see FIG. 4), stops midway, and moves away toward the drained liquid 12 and does not flow. Therefore, the terminal end of the lower line electrode 9b in the upper stage The drain liquid 12 is configured to be connected to the drain liquid 12 via the drain liquid 12 . Since the upper line electrode 9a draws out a large amount of condensate as described above, the centrifugal force acting on the condensate is large, and the condensate can reach the drained liquid 12. Note that the present invention is not limited to the above embodiment, and the lower wire electrode 9a by the upper stage
The terminal end 11b of the lower wire electrode 9a in the lower Y
It may also be configured to communicate with the starting end of.
本実施例は、次のように作用する。 This embodiment operates as follows.
伝熱管3を一方の電極とし、且つ線電極9a,

き出す。 The heat exchanger tube 3 is used as one electrode, and the wire electrodes 9a,
9b is used as the other electrode, and a high voltage is applied between them. Then, since the heat exchanger tube 3 is planar and the wire electrode is linear, an unequal electric field is formed between them, and the heat exchanger tube 3
A force in the direction of the wire electrodes 9a, 9b acts on the molecules of the condensate on the surface 8, and the condensate is drawn out toward the wire electrodes 9a, 9b.
線電極9a,9bが2重に巻かれているため、

て下方に排出される。 Since the wire electrodes 9a and 9b are wound twice,
The amount of condensate drawn out is larger than that of a single wire electrode. It is transmitted on the wire electrode 9a by centrifugal force, is connected to the drained liquid 12, and is caused to flow down the drained liquid 12 by gravity and is discharged downward. Further, the condensate drawn out to the lower line electrode 9b in the upper stage flows down and is discharged downward.
線電極9a,9bの螺旋の傾斜が下方にいくに
従つて急角度となり凝縮液に作用する遠心力が増
加されているので、線電極9aから排液体12へ
の連絡が確実に行え、途中で静止してしまうこと
がない。 As the spiral slope of the wire electrodes 9a, 9b becomes steeper as it goes downward, the centrifugal force acting on the condensate increases, so that the wire electrode 9a can reliably communicate with the drained liquid 12, and It never stands still.

で排出することができるものとなる。(Effects of the Invention) As already mentioned, in the case where a double helix wire electrode is simply installed, the amount of condensate adhering to the lower wire electrode of the double helix wire electrode is small; Since the centrifugal force acting on the liquid becomes smaller than the force exerted by the electric field, the condensate is not discharged. However, in the present invention, the terminal end of the lower line electrode in the upper stage is connected to the starting end of the lower line electrode. , even if the amount of condensate attached to the lower wire electrode is small,
The condensate can be applied to the starting end of the lower wire electrode and discharged at the lower stage.
