FIRE DAMP PRODUCING DEVICE Russian patent published in 1997 - IPC

FIELD: metal cutting, surfacing and sanitary jobs; devices for generating fire damp. SUBSTANCE: device has electrolyzer with electrodes 1,2 with gas outlet holes and pressure reservoir 3 connected with electrolyzer by means of gas discharge and electrolyte delivery device, dryer 2 made in form of chamber mounted on pressure reservoir 3 and connected with the latter by throttling hole or valve 10 and check valve 11 to discharge condensate. Gas discharge and electrolyte delivery device is made in form of three concentrically arranged pipes 4,14,17. First inner pipe 17 is installed on jumpers on outer pipe 4 which connects pressure reservoir 3 and ring 2 placed between sets of electrodes. First inner pipe 17 is installed on jumpers. Upper end of inner pipe 17 forms clearance with bottom of pressure reservoir and is located above gas outlet holes 15, and lower end of pipe 17 is located below gas outlet holes 15. Upper end face of second inner pipe 14 is secured on bottom of pressure reservoir 3 and is aligned with hole to let out gas and to deliver electrolyte in bottom of pressure reservoir. Lower end of pipe 14 is arranged above gas outlet holes of electrodes. Deflector 13 is installed over hole in bottom of pressure reservoir. EFFECT: enlarged operating capabilities. 1 dwg
