FIELD: ventilation equipment for domestic and industrial heat-using plants and exhaust ventilation of living spaces and production areas. SUBSTANCE: the device has a chimney with a nozzle section, having an axis-symmetric flue and an exhaust port, ventilation skip with a pipe connection equipped with an exhaust port. The device is featured by a mixing chamber with an axisymmetric flue brought out into the atmosphere through the exhaust port and connected to the exhaust ports of the ventilating pipe connection and the pipe nozzle is built in the ventilating pipe connection with formation of an annular duct for ventilation air, and the ducts of the mixing chamber, ventilating pipe connection and the pipe nozzle section have a common axis of symmetry. EFFECT: reduced power consumption and enhanced efficiency of exhaust of the ventilation flows with the use of the energy and dynamic head of the flow of flue gases discharged into the atmosphere. 5 dwg |
