Explosion Suppression and Chemical Isolation Systems
Standard features:
- Type IPD system - explosion suppression and isolation systems detect the earliest stage of a deflagration by sensing the pressure wave that comes ahead of the flameball and uses the signal to activate delivery of an extinguishing agent
- A typical system consists of the following:
- Sensor
- Power supply module
- System monitor
- Several explosion suppression ‘cannons’
Product Offerings
Spark Detection & Extinguishing Solutions
Spark Detection, Flame Detection and Hot Particle Detection. Extinguish Without Stopping Production. Prevent Fire and Explosion Risks in Downstream Equipment. Activate Alarm and Control Systems. A Flexible Modular Design Allows for up-to-34 systems to be monitored through modular expansion.
Explosion Isolation Knife-Gate Valves
Designed to respond in the manner of an ‘air bag’ in a vehicle, when the IVE isolation valve is directed to close, an inflatable bladder immediately fills the body cavity to stop product flow and arrest flame propagation. This operating mode minimizes the reaction forces generated by the IVE valve. The BS&B Type IVE valve is available in sizes from 4” to 16” nominal diameter (100mm to 400mm). Activation of the valve can be by BS&B supplied pressure or optical sensors.
Explosion Isolation Chemical
Cannons may be installed in any orientation. Low mass and low reaction forces minimize installation costs for thin walled pipes and ducts. Intrinsically safe field wiring circuits eliminate the expense of explosion proof conduit. Pressure detector voting arrangement minimizes risk of activation from vibration and abnormal process pressure excursions. Replacement suppressant pre-packed in sealed canisters ensuring error free refit with minimal cleanup.
Mechanical Isolation Barriers
The mechanical isolation device applied must be designed to survive the maximum explosion pressure for the process material, Pmax. In addition, all of the piping and equipment upstream of the isolation device must also be designed to accept Pmax.
