A device for the combined extinguishing of large-scale fires and fire-explosion prevention of foam low and medium multiplicity

摘要

The invention relates to fire extinguishing and fire and explosion prevention techniques, namely, devices for extinguishing large-scale fires of classes A and B and for fire and explosion prevention by air-mechanical combined foam of low and medium multiplicity. low fire area and increase the safety of the process of extinguishing fires and fire and explosion prevention explosion-hazardous facilities, a device for combined fire extinguishing and fire and explosion prevention with foam of low and medium multiplicity contains two generators of combined foam of low and medium multiplicity fixed to the traverse and means of automated traverse turns with foam generators fixed on it in the vertical and horizontal planes are made with the possibility of their connection to the remote system remote control and remote control via remote control or radio signals remote control system. The means of automated traverse turns with foam generators mounted on it in a vertical plane are made in the form of an actuator containing a linear drive and an electric motor, and the means of automated traverse turns with foam generators mounted on it in a horizontal plane contain a gear transmission of rotation and an electric motor. Each of the foam generators mounted on the traverse contains a housing with a package of media foam generation grids placed inside the housing s multiplicity upstream of the housing unit injector feeding an aqueous solution of foaming meshes per packet generating medium expansion foam, the barrel forming low expansion foam, a pipeline for supplying a foaming agent to the aqueous solution of the nozzles and the trunk low expansion foam forming and foam generator means for connection to the flowline. 13 s.p. crystals, 7 ill., 2 tab.
