立された技術となるにいたっていないのが現状である。Problems with the Prior Art In recent years, communication using optical fiber cables has been attracting attention as a means of transmitting information, and it is well known that the demand for it is increasing year by year. However, since the manufacturing technology of such optical fibers is a cutting-edge technology, there are various problems with its exhaust gas treatment, etc. Currently, conventionally known exhaust gas treatment techniques and equipment are used as they are, and they are not yet fully established. The current situation is that it has not yet become a technology.

ICIGeC14+2H20-GeO2+HC1 Therefore, the exhaust gas discharged from the process of manufacturing optical fibers by such a method contains solid particles such as 5i02 and G e O2 and chlorine compounds such as HCI and CI2. For this reason, conventionally, in order to treat these gases, they are washed with water or an alkaline solution. However, simply washing the above gas with water is insufficient to remove HCI, CI2, etc., and when washing with an alkaline solution, the 5i02 in the gas reacts with the alkaline component, and as shown in the following equation, the removal of HCI, CI2, etc. This results in the formation of precipitates and solids that are difficult to filter.
This time, it has become difficult to dispose of the waste liquid.

20 Furthermore, the solid particles in the gas are fine particles generated by a gas phase reaction, and the removal of the solid particles is insufficient only by a combination of water washing and alkaline washing. In particular, these can cause scaling to exhaust fans and ducts,
This makes long-term stable operation difficult.

Exhaust gas treatment in the optical fiber manufacturing process, consisting of an electric pot U machine having a structure that includes a plastic dust collection electrode made of plastic and a cleaning spray that washes the dust collection electrode with water from time to time, and an absorption tower that removes chlorine compounds from the exhaust gas.

れていなかった。Among the various types of dust collectors, the electric dust collector shows the highest dust collection efficiency, but if the exhaust gas contains chlorine compounds, the electric dust collector is 4! Because of problems with the corrosion resistance of dust collectors, it was customary to install a scrubber with alkaline cleaning in front of the electrostatic precipitator to remove corrosive gases before installing the electrostatic precipitator. However, as mentioned above, in the case of exhaust gas from the optical fiber manufacturing process, if alkaline cleaning is performed in the first stage, precipitates and solids that are difficult to filter will be generated in the cleaning waste liquid, making it extremely difficult to treat the waste liquid.
Furthermore, in the case of water washing or alkaline washing, there is a problem in that a large amount of waste water is generated. Therefore, it has been virtually impossible to apply an electrostatic precipitator to the exhaust gas from the optical fiber manufacturing process.
そこで、本発明者等は耐食性の電気集塵機を用いた小型
