Dust explosion protection in Europe

ELEVEX explosion suppression system for bucket elevators

Producer: RSBP

The most common way to protect people and equipment in an elevator is to suppress an explosion at its inception stage. This is done by using sensors that respond to an increase in pressure or temperature and by using cylinders (containers) with an inert substance. Usually an ABC powder or WATER SHOT cylinder of water is used.

Description

The ELEVEX system detects the source of danger and uses the controller to trigger the explosion suppressant containers. As a result, the primary explosion is extinguished at the nucleation stage and no secondary explosion takes place. The entire process takes no more than 60 ms.

The ELEVEX system consists of explosion detectors, HRD barriers on the inlet and outlet piping, HRD system on the elevator head and elevator boot.

The principle of its elements is the same: to detect and suppress an explosion. These devices also include similar components:

  • Detectors consisting of a sensor, a sensor and a contactor;
  • CONEX controller;
  • HRD cylinder with extinguishing agent.

The difference is that HRD barrier dampers use specially shaped nozzles which distribute the explosive powder in a fan. This captures a larger area to contain the explosion.

WATER SHOT cylinders are the same as HRD cylinders but with water. They are used where there are strict hygiene requirements and the extinguishing powder affects the quality of the final product that passes through the transport system.

Advantages

  1. Quickly detects and suppresses an explosion – the whole process takes no longer than 60 ms.
  2. Dampers are easy to replace once triggered.
  3. No explosion products leave the elevator.
  4. The ELEVEX explosion suppression system is easily adaptable to the conditions of the existing process. There is no need to carry out equipment upgrades. Installation is carried out with minimal interference to the elevator devices.
  5. Maintenance is carried out without special tools or experts. We can provide you with clear and detailed instructions for use.
  6. The ELEVEX system can be used in open areas and in confined spaces.
Technical features

The HRD barrier uses a DETEX type pressure detector as well as LUMEX 1 and LUMEX 3 type optical infra-red detectors.

The CONEX control centre is available in two-zone, four-zone, six-zone or eight-zone versions. It features a system status display and service mode switches. The integrated rechargeable battery guarantees at least 4 hours of autonomous operation in the event of a power failure.

The HRD cylinder uses ABC fine extinguishing powder: FUREX 770, SODA BICARBONA, TROPOLAR FORTE etc. or water.

Installation

The sensors and HRD-Balloons (active elements) are installed in the pipelines. Mounting is by means of mounting adapters, receivers, holders, flanges, etc. Documentation with drawings is included to help you understand the mechanical assembly.

In the second step, the cabling is connected and the system is set up and parameterised. The HRD barrier is then brought into service. The equipment is accepted and handed over to the customer and appropriate induction training is provided. The delivery documentation includes a section on electrical equipment to assist in this phase.

We will hand over to the customer:

  • Operating manual
  • Set of assembly drawings
  • Assembly instructions
  • Certificates of сonformity
Maintenance

A detailed user manual in Russian is included in the scope of delivery. On the basis of this, the customer draws up his own instruction manual in which he describes the action to be taken by the personnel.

Technical maintenance of the HRD barrier consists of constant optical and visual inspection for cleanliness, mechanical integrity of all components. Once a month it is necessary to carry out the following actions:

  • Maintenance of the pressurised air supply for blowing out the optical detectors, if used;
  • Monitoring the operating pressure on the HRD cylinder pressure gauges.

All faults are reported to ATEX.CENTER by the customer.

The hrd barrier is serviced at the intervals specified in the operating manual:

  • Once every 6 months – checks of HRD system and/or HRD barrier (control units, detectors, HRD receptacles);
  • Once a year – checks of HRD receptacles, nozzles, extinguishing medium and its distribution, pipes;
  • Every 3 years – replacement of the internal accumulator in control units (batteries), replacement of the HRD activator;
  • Every 10 years – pressure test of HRD receptacles in accordance with the applicable statutory regulations.
