Problems solved by technology

[0002] Marine explosion-proof hydraulic axial flow fans generally drive the fan blades to rotate at high speed for gas exchange. Since the supporting power system of the ship supplies power for the fans, the live fans are prone to safety accidents in some sealed spaces, so fire water circulation is adopted. To drive the fan to rotate, but due to the design problems of the traditional fan, the circulating fire water cannot be effectively used, and the ventilation effect is poor

Abstract

The invention discloses an exhaust assembly of a water-drive and non-electric exhaust fan. The exhaust assembly comprises an exhaust shell and an exhaust inner cylinder. The lower end of the exhaust inner cylinder is cylindrical, and the upper end of the exhaust inner cylinder is conical. The upper layer of the exhaust inner cylinder is provided with a fixing blade which is connected with the exhaust shell, and the lower layer of the exhaust inner cylinder is provided with a guide wheel blade which is connected with the exhaust shell. An impeller is driven to rotate through circulating of circulating fire fighting water in a ship body. The shape of concave blades in a turbine shell is improved, and therefore the conversion rate of water kinetic energy is improved, exhaust wind pressure is improved accordingly, and the ventilation distance of air in the ship body can be effectively increased by 30 meters.

Description

Technical field: [0001] The invention relates to a ventilating device, in particular to an exhaust assembly of a water-driven non-electric exhaust fan. Background technique: [0002] Marine explosion-proof hydraulic axial flow fans generally drive the fan blades to rotate at high speed for gas exchange. Since the supporting power system of the ship supplies power for the fans, the live fans are prone to safety accidents in some sealed spaces, so fire water circulation is adopted. To drive the fan to rotate, but due to the design problems of the traditional fan, the circulating fire water cannot be effectively used, and the ventilation effect is poor. Invention content: [0003] The purpose of the present invention is to provide a water-driven non-electric exhaust fan exhaust assembly, in order to improve the defects of the background technology, effectively utilize the fire-fighting water kinetic energy resources in the hull, and provide ventilation effects. [0004] In o...
