AUTOMATIC EXPLOSURE ISOLATION BARRIER Russian patent published in 2017 - IPC E21F5/14 

FIELD: fire safety.

SUBSTANCE: an automatic explosure isolation barrier is proposed. It comprises a control unit connected to the dispatcher through a communication line, cylinders filled with extinguishing agent, liquid and inhibitor spraying blocks and sensors. Furthermore the liquid spraying blocks are secured in openings around the perimeter and located in the sequence as follows: the first block for gaseous inhibitor spraying, connected to the cylinders with an inhibitor, and the second block for liquid spraying, connected to both permanently installed and autonomous water supply systems. The control unit is connected with the light and heat sensors and pressure sensor. Furthermore, the control unit and inhibitor cylinders are located in an explosion proof enclosure.

EFFECT: increased level of protection during isolation of methane-air mixture and coal powder explosion sequentially using different action barriers.
