| 摘要 |
The present invention relates to a preventive safety system which may be used in a process in which looselyformed process material is produced in a first unit (1) and is transportable to a receiving, second unit (2), and in which process the treatment of material in the first unit is liable to generate a hazardous particle or particles which has/have a temperature which is sufficiently high to inidate burning and/or an explosion in at least the second unit. The requisite transportation of the loosely-formed material between the first unit and the second unit is effected through the medium of a stabilizing zone (7), an indicating zone (9) operative in indicating the presence of hazardous high-temperature particles, and an extinguishing zone (9), wherein the indicating zone (8) includes one or more hazardous particle sensors, wherdn the sensors coact with an indicating and activating unit (12) such that when the presence of hazardous high-temperatures particles is detected by a sensor (10) in the indicating and activating unit (12) there is activated a device (15) which is located in the extinguishing zone and which functions to deliver an extinguishing agent and/or to remove said hazardous particles from the system. A detection-dependent intensity can be evaluated in the activating unit (12) and that measure or procedure which is most suitable at that time selected in the indicating and activating unit (12) from a number of available safety measures and safety procedures (19, 20, 21).
