【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、水室内にオゾン発生管を組み込んだ水冷
式オゾン発生装置に関する。Description: TECHNICAL FIELD The present invention relates to a water-cooled ozone generator in which an ozone generating tube is incorporated in a water chamber.
従来、オゾン発生管の両端が貫通する一対の管板で水
室を形成し、この水室に冷却水を貫流させたり、風冷と
同時に冷却水をシャワー状に滴下させるものが知られて
いる（例えば特公平１−59964号公報）。Conventionally, a water chamber is formed by a pair of tube sheets penetrating both ends of an ozone generating tube, and cooling water is allowed to flow through the water chamber, or cooling water is dropped in a shower shape simultaneously with air cooling. (For example, Japanese Patent Publication No. 1-59964).

ものに相当する。FIG. 4 is a cooling water pipe diagram including a schematic side sectional view of an ozone generating pipe and a water chamber of a conventional example, and FIG. 5 is a schematic front sectional view of the ozone generating pipe and a water chamber of FIG. FIG. 4 is a diagram of a treated gas pipeline also shown, which corresponds to a case in which cooling water flows through a water chamber of the above-mentioned document.
図において、端部1aに取扱気体の出入口と電極端子を
備えるオゾン発生管１の両端を一対の平行な管板２に気
密に貫通させ、この管板で形成される水室３に熱交換器
４を貫流する冷却水をポンプ５で循環させるように水冷
式オゾン発生装置を構成する。In the figure, both ends of an ozone generating tube 1 provided with an inlet / outlet of a handling gas and an electrode terminal at an end 1a are airtightly penetrated through a pair of parallel tube sheets 2, and a heat exchanger is formed in a water chamber 3 formed by the tube sheets. The water-cooled ozone generator is configured to circulate the cooling water flowing through the pump 4 with the pump 5.
オゾン発生管１に高電圧を印加し、管板２の外側の一
方の管６に取扱気体７である空気又は酸素を導入すれ
ば、オゾン発生管１で取扱い気体の一部はオゾンO3とな
り、他方の管８からオゾンを含む取扱気体９が得られ
る。When a high voltage is applied to the ozone generating tube 1 and air or oxygen as the handling gas 7 is introduced into one of the tubes 6 on the outside of the tube sheet 2, a part of the handling gas in the ozone generating tube 1 becomes ozone O 3 . A handling gas 9 containing ozone is obtained from the other pipe 8.
オゾン発生管１におけるオゾンの生成過程において、
オゾン発生管１は発熱する一方、オゾンの生成濃度はオ
ゾン発生管１の環境温度の低いほど良好である。したが
って水室３内でオゾン発生管１を冷却水により冷却す
る。In the process of generating ozone in the ozone generating tube 1,
While the ozone generating tube 1 generates heat, the ozone generation concentration is better as the ambient temperature of the ozone generating tube 1 is lower. Therefore, the ozone generating tube 1 is cooled in the water chamber 3 by the cooling water.
前記の従来例において、オゾン発生管周辺の流速を考
えると、周知のごとく流体中の物体であるオゾン発生管
の表面の水の速度は零であって、表面から離れに従って
ある勾配を持って速度は増す。すなわちオゾン発生管表
面及びその近傍の速度は平均速度よりはるかに小さいの
で熱交換率はあまり良くない。一方、冷却水を外部の熱
交換器を介して供給するものでは、導入される冷却水の
温度は充分低いので平均流速をあまり大きくしない。例
えば、0.05〜0.1m/sである。すなわち表面及び近傍の速
度は平均速度より小さく、平均速度自体も小さくて熱交
換率は良くないのである。In the conventional example described above, considering the flow velocity around the ozone generation tube, as is well known, the velocity of water on the surface of the ozone generation tube, which is an object in the fluid, is zero, and the velocity increases with a certain gradient from the surface. Increases. That is, since the speed at and near the surface of the ozone generating tube is much smaller than the average speed, the heat exchange rate is not so good. On the other hand, when cooling water is supplied via an external heat exchanger, the temperature of the introduced cooling water is sufficiently low, so that the average flow velocity is not so large. For example, 0.05 to 0.1 m / s . That is, the velocities at and near the surface are lower than the average speed, the average speed itself is low, and the heat exchange rate is not good.
そこで循環する冷却水の流量を増すと、管路、特に熱
交換器内の流体圧力損失が増大し、ポンプとその動力が
過大になり実用的でない。Therefore, if the flow rate of the circulating cooling water is increased, the fluid pressure loss in the pipeline, especially in the heat exchanger increases, and the pump and its power become excessive, which is not practical.
この発明の目的は、熱交換器を経由する冷却水の循環
流量を大きくすることなく、水室内の熱交換率を向上さ
せることにより、より低い温度でオゾンの生成を行って
オゾン濃度を向上させ、オゾン生成効率を向上させるこ
とができる水冷式オゾン発生装置を提供することにあ
る。An object of the present invention is to improve the heat exchange rate in the water chamber without increasing the circulation flow rate of the cooling water through the heat exchanger, thereby generating ozone at a lower temperature and improving the ozone concentration. Another object of the present invention is to provide a water-cooled ozone generator capable of improving ozone generation efficiency.
この発明１の水冷式オゾン発生装置は、 端部1aに取扱気体の出入口と電極端子とを備えるオゾ
ン発生管１の両端を一対の平行な管板２に気密に貫通さ
せ、この管板で形成される水室３に熱交換器４を貫流す
る冷却水をポンプ５で循環させる水冷式オゾン発生装置
において、 前記水室３に対し、補助ポンプ13を備えた補助管路14
を前記ポンプ５と並列接続するものである。In the water-cooled ozone generator of the invention 1, both ends of an ozone generating tube 1 having an inlet / outlet of a handling gas and an electrode terminal at an end portion 1a are air-tightly penetrated through a pair of parallel tube sheets 2 and formed by this tube sheet. In a water-cooled ozone generator for circulating cooling water flowing through the heat exchanger 4 into the water chamber 3 by a pump 5, an auxiliary pipe 14 having an auxiliary pump 13 is provided for the water chamber 3.
Are connected in parallel with the pump 5.

る。A water-cooled ozone generator according to a second aspect of the present invention is the water-cooled ozone generator according to the first aspect, wherein a flow direction of the water flow by the pump and a flow direction of the water flow by the auxiliary pump in the water chamber are the same.
発明３の水冷式オゾン発生装置は、 端部1aに取扱気体の出入口と電極端子を備えるオゾン
発生管１の両端を一対の平行な管板２に気密に貫通さ
せ、この管板で形成される水室３に熱交換器４を貫流す

において、 前記水室３内に冷却水を撹拌する撹拌スクリュー21を
設けるものである。A water-cooled ozone generator according to a third aspect of the present invention is formed by air-tightly penetrating both ends of an ozone generating tube 1 having a gas inlet / outlet and an electrode terminal at an end 1a through a pair of parallel tube sheets 2. In a water-cooled ozone generator for circulating cooling water flowing through a heat exchanger 4 into a water chamber 3 by a pump 5, a stirring screw 21 for stirring the cooling water is provided in the water chamber 3.

流速が増す。したがってオゾン発生管１との熱交換率が
向上し、オゾン発生管は良く冷却され低い温度でオゾン
発生管がオゾンの生成作用を行うのでオゾン濃度が向上
してオゾン生成効率が向上する。In the invention 1, since the flow in the water chamber 3 by the auxiliary pipeline 14 having the auxiliary pump 13 connected in parallel does not flow through the pump 5 having the heat exchanger 4,
Does not increase the fluid pressure loss in the pipeline. Nevertheless, in the water chamber 3, the flow rate of the sum of the flow rate of the pump 5 and the auxiliary pump 13 flows, and the flows are mixed and agitated or the flow rate increases. Therefore, the rate of heat exchange with the ozone generating tube 1 is improved, and the ozone generating tube is cooled well and the ozone generating tube performs an ozone generating operation at a low temperature, so that the ozone concentration is improved and the ozone generation efficiency is improved.

を同一にするので混合作用より流速増大の作用が大き
い。逆説的には、流れの方向を交差させたり、反対方向
に適宜に配管位置を変えて流速の作用より混合撹拌作用
を利用する手段もあり得る。In the second aspect, since the flow directions of the pump 5 and the auxiliary pump 13 are made the same, the effect of increasing the flow rate is greater than the mixing action. Paradoxically, there may be a means in which the direction of the flow is crossed, or the position of the pipe is appropriately changed in the opposite direction to use the mixing and stirring action rather than the action of the flow velocity.
発明３において、水室内の撹拌スクリュー21により撹

熱交換率が向上する。According to the third aspect of the present invention, by stirring with the stirring screw 21 in the water chamber, a turbulent flow is generated near the ozone generating tube surface, and the heat exchange rate is improved.
