ELEVEX – Explosion protection of bucket elevators

ELEVEX is the effective solution of bulk material vertical transport explosion protection. ELEVEX reduces explosion pressure to an extremely low value, which means that even existing and used technologies can be safely protected in case of explosion completely without destructive effects. The list of factors that can cause an explosion in a bucket elevator or similar vertical transport system is long, and the probability the an explosion will occur during operation is high. Although use of this system does not prevent origination of an explosion in an elevator, the actual explosion effects can be brought to a minimum.

Advantages: 

  • Tested protection system
  • High quality of used components
  • Simple installation even onto already existing technologies
  • Maximum protection with minimum costs
  • Suitable also for high elevators

The most frequent initiation sources in bucket elevators are:

  • Sparks caused by deviation of traction system from its axis
  • Sparks from the elevator drive or hot elevator surfaces caused by friction
  • Glowing particles introduced together with transported material
  • Bearing friction, etc.

The ELEVEX system offers variability protection for both internal and external applications.

In case of explosion inside the elevator there is not only a large risk of destruction of the whole production technology, but mainly injury or death of workers. In case that an unprotected equipment is destroyed the Operator does not face only incredibly high costs related to the acquisition of a new elevator and renewing of production, but also large downtime related to this replacement or renewal of technology.

 The ELEVEX system contains variable protections both for internal and external applications. ELEVEX system offers various customer-based combinations.

Explosion suppression

Explosion suppression is the most frequent and the most widely used way of explosion protection of bucket elevators.

Components:

  • Explosion detector
  • Barriers preventing explosion transfer at the bucket elevator entrance and exit to connected technologies and devices
  • Explosion suppression at the elevator head and foot

Advantages:

  • Reduces explosion pressure to an extremely low value, which means that even existing and used technologies can be safely protected in case of explosion without destructive effects
  • Safe and suitable way of protection of elevators located outside and inside of buildings
  • Economically advantageous solution

 

 

Explosion venting

During explosion venting it is expected that the flame and pressure waves will relieve themselves through the vent opening to a safe space.

Components:

  • Explosion detector
  • Barriers preventing explosion transfer at the bucket elevator entrance and exit to connected technologies and devices
  • Especially developed explosion venting devices or flameless devices are used for venting

Advantages:

  • Extremely quick decrease of explosion effects
  • Effective, economically advantageous solution, low costs and easy installation
  • Optional panel opening sensors and heat insulation
  • Suitable for elevators located outside of buildings
  • In the case of explosion will safely protect even existing and already used technologies without destruction effects

Flameless explosion venting

For flameless venting is used FLEX device, which stops flame and heat propagation and reduce explosion pressure in the same moment.

Components:

  • Explosion detector
  • Barriers preventing explosion transfer at the bucket elevator entrance and exit to connected technologies and devices
  • Flameless explosion venting

Advantages:

  • Effective arrest of flame and heat and provision of a safe zone for movement of personnel, equipment and buildings
  • Effective retention of dust
  • High effectivity and reliability of the system
  • Simple installation and maintenance-free operation
  • Elimination of high costs for building modifications
  • Economically advantageous solution
  • In the case of explosion will safely protect even existing and already used technologies without destruction effects
