Q-Bic™

Active isolation.

In practice, many vessels, silos and devices are connected by pipes, pneumatic conveyors and dust extraction or aspiration lines. If a dust explosion occurs, the flames and pressure waves can spread through these conduits to other parts of the plant. Pre-compression and flame jet ignition exacerbate the explosion in connected vessels. The results is a series of secondary explosions that cause even more catastrophic damage. An isolation system prevents explosions from propagating and thus minimises the consequences of an explosion. It ensures optimum protection for adjacent parts of the plant. Active systems have detectors or sensors which register the pressure rise or flames and trigger countermeasures, e.g. closing a valve.

Application

The explosion isolation system Q-Bic™ is specifically suitable for large pipes or complex shafts geometrics for example in conveyors or bucket elevators in various industry applications.

Advantages

Effective discharge of the QXP™ via the spin jet extinguish nozzle SJX™.
Green extinguishing powder QXP™ prevents cross contamination after activation.
Electrical monitored pressure gauge.
Easy handling due to integrated transport holder.
Most cost-effective way to isolate large pipes.
Flexible use due to variable mounting distances.
Suitable for use at ambient temperatures from -20 °C to +60 °C.
Hygienic mounting material available.
Smart triggering device without explosives simplifies import.

Mechanism

The Q-Bic™ explosion isolation system detects an explosion in its very earliest stages and extinguishes the explosion flames within milliseconds by introducing the extinguishing powder QXP™. The special nozzle system SJX™ ensures optimum distribution of the extinguishing powder in the pipe. Thus ensured a secured isolation.

The combination of Q-Bic™ and flameless explosion venting prevents pressure and flames from spreading to other parts of the system.

REMBE^® Q-Bic™ on a spray dryer.

Usually, spray dryers are protected with a combination of isolation systems and vent panels. If a free and safe relief is not possible, the vent panels are replaced by a flameless venting device. To prevent explosion propagation, the connecting pipes are usually isolated with Q-Bic™ chemical barriers.

REMBE^® Q-Bic™ on an elevator.

Elevators convey large amounts of (combustible) bulk materials, and thus pose a high risk for an explosion. The size and strength of the bucket elevator determine the number and mounting distance for the required protective systems, depending on the bulk material involved. The isolation of the up/down stream conveyors is usually performed with rotary valves or Q-Bic™ chemical barriers.
