Abstract

Apparatus for monitoring the temperature of adsorbers formed from several segments in which a traveling carbonaceous fill is located between two perforated walls, through which the gas to be cleaned flows. Each segment has on the gas outlet side several measuring elements, responding at a predetermined temperature and distributed over the height and width of the exit cross section. These measuring elements are electrically connected in series and their lead-ins are connected to a power source and an indicator instrument located outside the segment. On the outside perforated wall, insulators are located, with a continuous soldering wire placed between them. Prefabricated fusible cutouts may be used as measuring elements and may be connected by electrical lines. Semiconductor resistors may also be so used. Each segment may have a thermocouple on the gas exit side which can travel throughout the entire height of that side. Separately charged ntirogen lines may be provided for cooling.
