| 摘要 |
The invention is a system which separates and reclaims a gas, e.g. methane, an aqueous fluid, e.g. water, and solids, e.g. coal from a slurry mixture. One application of the invention is in the degasification operations of underground mining. The system is hermetically constructed for the safe separation, collection and reclamation of the various components of the mixture. Included in the structure of the system are a substantially airtight enclosure (10) which contains a trough-like passageway (20) for delivering the mixture into the enclosure (10), gas vents (25) and a collection manifold (26) for collecting the released gas; a filter assembly (42) for clarifying the aqueous fluid and reclaiming the fluid from the system for reuse, solids removal mechanisms for continuously transporting separated, settled solids from the enclosure interior (19) to a location exterior to the system, a dual-functional mechanism (62,65) for supplying make-up water to the system, a mechanism (67,68) for controlling the supply of the make-up water, a dual-functional skimmer mechanism (80), an emergency outlet (86) for releasing the mixture from the enclosure, and a mechanism (87,88,90,92) for closing the emergency outlet (86) during normal operation of the system and opening the outlet when necessary to accommodate high flows of mixture within the enclosure.
