Abstract: A solar fail-safe device according to an embodiment of the present disclosure is capable of operating a valve by using sunlight and operating the valve in an emergency in which electricity is not supplied to an actuator unit moving the valve. A solar fail-safe device may include a solar panel module producing electricity from solar energy, an actuator unit including an actuator moving a valve by using electricity as a power source, and a fail-safe part moving the valve by using emergency electricity with which the fail-safe part is pre-charged, and a control unit receiving the electricity produced from the solar panel module to charge a first and a second battery and to supply the electricity to the actuator unit. The actuator may move the valve by using the emergency electricity when a voltage at which the electricity is applied from the control unit is less than a predetermined value.

Abstract: The present invention discloses an apparatus and method for treating perfluoro-compounds (PFCs). The method for treating PFCs includes: (a) decomposing PFCs and eliminating a first acid gas generated by the decomposition through a pre-cleaner; (b) filtering out dust particles from the exhaust gas through a filter; (c) electrifying the dust particles in the exhaust gas by electrical discharge and collecting dusts through a dust collector; (d) decomposing PFCs using a regenerative/catalytic reaction through a catalytic reactor; (e) eliminating a second acid gas generated by the regenerative/catalytic reaction through a post-cleaner; and (f) letting the purified exhaust gas out through a fan.
