Granted: 1995-06-19
Abstract: FIELD: fire signalization systems. SUBSTANCE: a smoke sensor has the body 1, in which the irradiator 2 with the first focusing lens 5 in front of it is mounted in such a way, that their optical axis are coincided, the photodetector 6, the reflector 5 in the form of hollow truncated cone, whose inner surface being mirror one, whose base plane being an elliptical surface and whose geometry axis is coincided with an optical axis of the photodetector and is inclined relative to an optical axis of the irradiator. Such structure of the reflector 5 provides more complete registration of a dissipated irradiation, directed forwards. An angle between the optical axis of the irradiator 2 and the elliptical surface of the cone reflector 5, being parallel with a line, passing through a focal point of the first focusing lens 3, is γ being calculated by the formula   where d-diameter of the first focusing lens, f-focal distance of the first focusing lens, a a distance from the irradiation source till the first focusing lens. In a zone of a small circular cross section of the cone reflector 5 the second focusing lens 7 is mounted. The sensor is provided by a spheric reflector 4, whose concave side is turned towards the reflector 5 and whose focal point being in a center of an elliptical cross section of the reflector 4. A distance from the optical axis till the base plane of the spherical reflector 4 is no less, than a half diameter of the first focusing lens 3. Such structure of the smoke sensor is effective in use, simple in production, provides increased range of angles of registration of dissipated irradiation due to using of the spherical reflector 4. A focusing of the irradiation with use of the first focusing lens 3 and predetermined arrangement of the cone reflector 5 allows to eliminated error signals, caused by fault operations. EFFECT: substantially increased sensitivity of the sensor being in a range (0.03-0.05)V/m independently upon a color of the smoke. 1 cl, 1 dwg

Multibarrel smoke stack is made in the form of self-bearing monolithic reinforced concrete structure having in its body four gas-branching barrels, elevator shaft, open through-passages for load-hoisting operations. Tapered half-circles of outer walls of gas-branching barrels are made in the form of truncated half-cones. Block-panels manufactured in factory conditions from acid- and heat-resisting material are installed over inner perimeter of gas-branching barrels and around elevator shaft. Before starting concreting of stack, each block-panel installed in design position is fixed by specific anchors to metal framework of barrels. Vertical joints between panels are filled with acid-resisting slurry through widened slots. After installing block-panels of first band of gas-branching barrels and elevator shaft, concreting of stack in whole is initiated. Rear wall of block-panels is concreted over entire surface of reinforced concrete barrels. This ensures integrity of all structural components of stack and its refractory lining with projected service life of 100 years and longer without overhaul repair of lining.
