ABSTRACT:
This invention provides a method of operation of a suction system which provides simultaneous decontamination of the suction system and a process for preventing accumulation of contaminants in the suction system. Due to a vacuum created by a vacuum pump, waste mixtures are extracted and flow, via high-speed and low-speed vacuum lines, to a vacuum trap housing which contains a vacuum trap having a solid-collecting screen. Chemical agents, serving as water-soluble decontaminants and being preferably in the form of tablets, are placed in the vacuum trap housing on the solid-collecting screen and are placed adjacent to a number of other filters at positions selected to assure that each waste mixture comes into contact with and is treated by the chemical agents before leaving the suction system. Activation of the chemical agents by each waste mixture causes the decontamination of the waste mixture and the breakdown and decontamination of accumulations in the suction system. The treated waste mixture flows from the vacuum trap housing via a main vacuum line, connecting the vacuum trap housing to the vacuum pump, towards the vacuum pump which is preceded by the number of filters. When the flow of the waste mixture stops and the chemical agents become dry, the release of the chemical agents is automatically discontinued.
