Bete creates connectors and wedge-lock system

Bete has designed connectors and a wedge-lock system for a waste-management/gas-scrubbing application where an incineration facility treats the combustion gases that occur.
This process required wet limestone slurry being injected into a gas stream, with an operating temperature in excess of 1,500F (815C) and containing chlorine and fluorine gasses.
Operational history indicated that the nozzles needed to be removed on a regular basis for essential maintenance.
As a result of this, there was a requirement for the connection points to be connected and disconnected faster than conventional connection flanges.
Although code compliance was not required, the geometry of the system was fixed, so there was a need for the design of the connections to meet specific dimensional requirements.
Bete designers came up with a solution based on the company's standard Spiralair lance design connector and produced a wedge-lock system that would fasten the mounting flange securely in place, which would still be quick and simple to connect and disconnect.
This wedge system allows the lance to be disconnected from the injection port by removing the two wedges with a slight tap.
Bete application engineers conducted research and then specified the air and fluid connections as commercial cam-lock fittings, which seal and release by the action of two small levers.
Other specific application requirements included the need to place the head of the spray in the centre of the vapour stream, so the length of the entire assembly had to be increased to more than 1.8m to achieve this.
Additionally, the lance was made from Inconel to withstand the corrosive vapour streams.
Bete is a distributor of standard and custom-designed spraying systems for a range of industries and applications and an exclusive distributor for spray-nozzle specialist Bete Fog Nozzle and pre-treatment spraying systems manufacturer Uni-Spray Systems.
