Explosion Protection Concept for Elevators

Based on the VDI guideline, REMBE® has developed a comprehensive protective system for elevators: ElevatorEX

Explosion protection is concerned with reducing the effects of an explosion and is the central, most frequently applied explosion protection concept. The explosion protective measures include conventional explosion venting using explosion vents, flameless venting, explosion isolation and explosion suppression. The following article explains how to protect elevators.

There are various venting options for the wide range of conveyors. Due to the functional and design-based conditions, elevators represent a special source of danger. Conveying a large amount of (combustible) bulk material carries a high risk of explosion. As with the previously mentioned plants, the elevator legs are usually protected outdoors with explosion vents and indoors with the REMBE® Q-Box or the REMBE® Q-Ball®.

Depending on the conditions at the installation site, a combination of conventional and flameless venting can also be the right safety concept. Quench valves can be installed to prevent explosion propagation via connected aspiration lines. The REMBE® Q-Bic™ extinguishing barrier is usually used to isolate the conveyors upstream or downstream.

Based on the VDI guideline, REMBE® has developed a comprehensive protective system for elevators: ElevatorEX
The first type-tested complete protective system for elevators offers a suitable solution for all types of elevators. Designed primarily for very high elevators, it combines the advantages of conventional venting with flameless venting and explosion suppression technologies.

REMBE Safety Days Digital Home Edition Success event continues via video conference
REMBE Safety Days Digital Home Edition
Success event continues via video conference In recent years, the ‘REMBE Safety Days’ series of events has repeatedly made Brilon a meeting place for global explosion safety and process safety. The content of the events was to present and discuss current topics in these areas as well as to create a platform for networking. In November 2019, 150 participants from five continents were welcomed to the Sauerland region. Unfortunately, no live events can take place due to the current situation. In order to nevertheless enable such an important exchange of knowledge, REMBE is offering a digital version of the REMBE Safety Days. Safety is essential – especially in difficult times like this. REMBE has launched the ‘REMBE Safety Days - Digital Home Edition’ to enable experts to continue to exchange their experience in the field of safety technology. “We are proud to be able to provide a platform like this,” says Claire Lloyd (Team Leader Process Safety Europe and one of the speakers at the REMBE Safety Days

Electrostatic with regard to explosion safety Notes on the evaluation and avoidance of electrostatic charges: FIBC filling stations; Pneumatic filling of silos; Conical pile discharge
Electrostatic with regard to explosion safety
Notes on the evaluation and avoidance of electrostatic charges: FIBC filling stations; Pneumatic filling of silos; Conical pile discharge Electrostatic charges can occur when two surfaces are rapidly separated, whereby at least one surface must be an insulator. Critical processes, for example, are pneumatic conveyors, Big Bag filling stations, or even silos with the danger of a conical pile discharge. FIBC filling stations In order to avoid electrostatic discharges at such FIBC filling stations, it is necessary to assess the bulk material and to select the proper FIBC Type. Type C Big Bag has conductive filaments, which allows grounding for safe filling / emptying. Such grounding can be carried out by means of a cable and clamp. Another option is the grounding by means of a grounding monitoring system such as FARADO fibc. An approval function enables the Big Bag Type C to only be filled if the grounding is correctly established. Pneumatic filling of silos Another source of electrostatic charges is in places where a pneumatic transport or pneumatic filling of silos by trucks is carried out. If

Q-Flap RX™ explosion isolation flap valve
Q-Flap RX™ explosion isolation flap valve
Explosion Isolation is absolutely necessary for a comprehensive safety concept. If a dust explosion occurs in one equipement, this also enhances the risk of flames and pressure propagation to other parts of the plant. Pre-compression and flame jet ignition exacerbate the explosion severity in interconnected vessels. The result is a series of secondary explosions that may cause even more catastrophic damage. An explosion isolation system prevents deflagrations from propagating and thus minimises the effects of an explosion. Adjoining plant components are optimally protected. A distinction is made between active and passive systems: Passive isolation systems such as explosion isolation flap valves make use of the overpressure of the explosion for their operating principle: Passive explosion isolation - this is how it works Passive explosion isolation systems respond purely mechanically to the propagation of pressure through its constructive design. Under normal operation,

REMBE Q-Ball REMBE product novelties: Q-Ball
REMBE Q-Ball
REMBE product novelties: Q-Ball The principal of flameless venting is a REMBE invention from the 1980s, which has changed the world of Explosion Safety like no other. It all started with the Q-Rohr, and is now continued with the Q-Ball. In addition to the requirement that neither flames nor pressure escape from the protection system, flameless venting devices should also be evaluated in terms of their venting efficiency and weight. Because: Low efficiencies mean that more / bigger venting areas and associated protection systems are required. A too heavy weight requires conversions to the vessel in order to ensure its stability. The Q-Ball, which is primarily designed for elevators and screens, uses the principle of the parallel contour relief developed by Roland Bunse. Thanks to the innovative design, the weight of the Q-Ball is very low. While comparable products from other manufacturers weigh around 45 kg, the Q-Ball which only weighs around 25 kg is an absolute lightweight, and 3 kg lighter than
