Triple rotary gas lock seal system for transferring coal continuously into, or ash out of, a pressurized process vessel |
摘要 |
A multiple rotary gas lock apparatus using a buffer seal gas is disclosed to enable the transfer of solid materials into or out of a pressurized process containing high temperature, flammable or toxic gases. The buffer seal gas, has a pressure higher than the process pressure and is introduced between two series connected gas locks; this prevents process gas backflow to the feed system. Buffer seal leakage gas from the first pair of gas locks and air from a third gas lock are removed from an opening in a connection between the pair of gas locks and the third gas lock at subatmospheric pressure. This system enables control and usuage of toxic or flammable gases as a buffer for mixing compatibility with the process gas when a suitable inert gas is not available. It also prevents the flow of any toxic gas to the worker environment.
