ABSTRACT:
A liquid seal for installation upstream of a flare stack or of a waste gas combustion installation to protect against flashback and to function as a pressure lock. During the operation of the seal, liquid is ejected upwardly from an inner annular chamber by a gas stream, and the ejected liquid is separated from the gas by a baffle plate and deflector arrangement so that the gas and liquid stream is directed downwardly, and a liquid film is formed which is broken down into individual streams by baffles. The gas escapes upwardly from the liquid seal in spaces between the streams of downwardly flowing liquid without entraining significant amounts of liquid. The downwardly directed liquid is collected in an outer annular chamber and flows into the inner annular chamber through a return opening to provide a constant circulation of liquid in the liquid seal.
