Inventor: APPLEFORD DAVID ERIC
IPC: F16K31/00
Filed: 2002-02-22
Abstract: A valve actuator (1) is provided which comprises an actuator stem (4) extending from a housing (2) which contains a sleeve (17). The actuator stem (4) is driven so as to cause the sleeve to compress a stack of springs (22) within the housing until bolts (25) engage the sleeve, locking the springs in a compressed state. At the same time an armature (28) on the actuator stem is attracted to an electromagnet (29) within the housing. The actuator stem can then be driven to open or close a valve in a controlled manner without first compressing or releasing the springs. In an emergency, the electromagnet is switched off, releasing the armature thus unlocking the stack of springs. The released springs push the piston which partially retracts the actuator stem into the housing causing the valve to be closed.

Abstract: A scrubber for exhaust gases comprises a series of nested counter-flow passages including a hot plenum having a star-shaped section. Exhaust gases from the hot plenum surge through a liquid bath and flow in a reverse direction through an inclined array of flat, overlapping, spaced mixing vanes, causing turbulence in the exhaust gases and the formation of highly dispersed tiny bubbles, which enhance the solution of gaseous pollutants into the scrubbing liquid. Mist eliminator vanes strip entrained liquids from the exhaust gases. The hot plenum, reheats the exhaust gases to an unsaturated level. The scrubber is highly effective in reducing particulate matter, stripping sulphur dioxide and nitrogen dioxide from exhaust gases, and reducing the heat signature and visual evidence thereof.
