却に供するようにしたものに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water treatment device using an electron beam irradiation device,
In particular, it relates to a system in which water to be treated flows through the irradiation window in contact with the irradiation window, and the treated water is used to cool the irradiation window, which becomes hot due to the passage of the electron beam.

下水処理においても水中に含まれる有害成分の除去に対
処しなければならなくなってきている。Due to the dramatic advances in chemical technology in recent years and the increasing density of the population, rivers and lakes are becoming increasingly polluted.
As wastewater standards for factories, etc. are becoming increasingly strict, it has become necessary to remove harmful components contained in water in water and sewage treatment as well.
一般に河川に排出されあるいは含まれる有害成分は水中

、現在では実用規模において利用し得ない。Furthermore, artificially produced harmful components such as cyanide, phenol, organic compounds, etc. cannot be reduced or removed by natural purifying effects as described above. Conventionally, water treatment equipment using radiation has been used to experimentally remove or reduce harmful components contained in water by irradiating treatment water with radioactive isotopes such as cobalt-6 clams. Handling of elements, maintenance, etc. are complicated, and there is a risk of dissipation of radioactive isotopes.
In addition, because the usable dose of the isotope is small, it cannot currently be used on a practical scale.

明する。Recently, attention has been paid to electron beams generated by electron beam irradiation equipment, and it has been considered to use the powerful energy to treat water such as sewage. However, when performing water treatment using this electron beam irradiation device, the problem is how to minimize overheating of the irradiation window due to the heat generated when the electron beam passes through the irradiation window. The present invention was made to solve this problem, and will be explained below according to an embodiment shown in the drawings.

次に、本発明の効果を具体的に実験データによって説明
する。This pipe line 10 has a water supply channel 11 above the irradiation window 4 and an outlet channel 12 below the irradiation window 4, and as shown in FIG. It flows from the front of the window 4 to the outlet waterway 12. By doing this, the entire external surface of the irradiation window 4 is cooled by the water to be treated 7. Therefore, the water to be treated 7 can be used as cooling water for the irradiation window 4, and a rise in temperature of the irradiation window 4 can be suppressed.
Next, the effects of the present invention will be specifically explained using experimental data.

りである。FIG. 3 shows the configuration of an irradiation window employing an air cooling method used as a comparative example of the present invention. In the figure, 20 is an irradiation pipe through which the water to be treated 7 passes, and a space 30 is provided between this pipe 20 and the irradiation window 4, through which cooling air 40 flows. And the beam output is 2 & 65
Table 1 shows the required cooling air pressure, air volume, and power for obtaining the cooling air in the electron beam irradiation device with mA and 10 skin A. 1. On the other hand, in the case where the irradiation window 4 is directly cooled by the water to be treated as in the present invention, the temperature rise of the water is suppressed to 10°C (for example, if 30°C water reaches 40°C). Table 2 shows the amount of water required for electron beam irradiation equipment with beam outputs of 28 hA, 65 hA, and 10 mm.

。Table 2: In each of the above tables, the size of the irradiation window 4 is 5 arcs x 45 arcs for beam output of 28 hA, 5 arcs x 120 arcs for 6 track beams, and 7 arcs x 7 arcs for 10 hA beam output. 180 enemies.
上記各表から明らかなように、水によって照射窓４を直
接冷却するようにしたものは「風冷の場合に〈らべて格
段に経済的であるとともに、冷却効果が大きい。As is clear from the above tables, the method in which the irradiation window 4 is directly cooled with water is much more economical than the case of wind cooling, and has a large cooling effect.
そして、汚水の照射処理において、被処理水を照射窓４
の冷却に用いることは、別途照射窓のための冷却装置を
用いる必要がなく、極めて効果的である。In the irradiation treatment of wastewater, the water to be treated is exposed to the irradiation window 4.
It is extremely effective to use the irradiation window for cooling, since there is no need to use a separate cooling device for the irradiation window.
