Abstract

The invention discloses a smoke exhaust jet device, which comprises a fan, a housing, an outer nozzle, a smoke exhaust pipe, a central nozzle and a mixing pipe; the fan is fixed on the first side of the housing; the outer nozzle is fixed in the housing , the large-diameter end is fixed in the first side, communicated with the fan to form a jet air flow channel, the small-diameter end is fixed in the second side of the housing, and communicates with the mixing pipe; one end of the exhaust pipe extends out of the housing, and the other end Extending into the outer nozzle, fixed in the second side, forming an air flow channel with the outer nozzle, and communicating with the mixing pipe; the central nozzle is fixed in the smoke exhaust pipe, and one end extends out of the smoke exhaust pipe to communicate with the jet air flow channel, and the other One end communicates with the mixing tube; the first end of the mixing tube is fixed on the second side, and the port diameter of the first end is larger than the diameter of the small-diameter end of the outer nozzle. The invention realizes the multi-flow channel design, provides excellent aerodynamic characteristics, reduces the vortex formed inside, realizes better jet flow effect, and improves the service life.

Description

technical field [0001] The invention relates to the technical field of smoke emission control application, in particular to a smoke exhaust jet device. Background technique [0002] Offshore platform is a comprehensive offshore engineering equipment for offshore oil drilling, storage, transportation and personnel living. It is a working base for subsea oil and gas exploration and exploitation. [0003] According to the structural characteristics and working status, it can be divided into fixed and mobile platforms. The semi-submersible offshore platform has gradually developed into the world's mainstream mobile platform in deep-sea oil extraction due to its strong anti-wind and wave capability, excellent motion performance, huge deck area and loading capacity, and high operating efficiency. The diesel generator set is the "heart" to ensure the normal operation of the offshore platform, providing power supply for each drilling equipment on the offshore platform and emergency...
