Problems solved by technology

Therefore, if there is no gas rectifier in the radial direction, and the axial length of the pipeline is short, it is difficult to ensure the uniformity of the aerodynamic parameters of the gas at the outlet of the cavity.

Abstract

The invention discloses a radial gas rectifier and belongs to the technical field of fluid flow control equipment. The radial gas rectifier comprises a gas inlet, an end plate, an outer ring plate, a front baffle plate, a rear baffle plate, an outer pipe and an inner pipe. An outer ring cavity is enclosed commonly by the outer ring plate, the front baffle plate, the rear baffle plate and the outer wall face of the outer pipe. The gas inlet is arranged on the outer ring plate and is communicated with the outer ring cavity. A plurality of rectifying holes are arranged on the outer wall face of the outer pipe surrounding the outer ring cavity. The radial gas rectifier is simple in structure and low in cost, functions of radially guiding and rectifying of gas can be achieved, inlet distortion fluid interference is effectively eliminated, and furthermore, functions of weakening and absorbing particular frequency vibration on some extent are provided.

Description

technical field [0001] The invention relates to fluid control equipment, in particular to a radial gas rectifier, and belongs to the technical field of fluid flow control equipment. Background technique [0002] Traditional gas rectifiers are divided into two types: plate and sheet, and these two rectifiers are widely used for gas diversion, vortex elimination, and velocity distribution adjustment; but most of the current gas rectifiers are shafts designed for circular or square pipes There are few gas rectifiers for ring cavity or square cavity pipelines, especially for cavities with small distance between inner and outer cavity surfaces. In the latter, due to the small distance between the inner and outer cavity surfaces, on the one hand, it is difficult to arrange a traditional axial gas rectifier in the flow channel; Air intake in radial direction. This one or more radial air intake methods determine that the gas entering the cavity is uneven from the beginning in the ...
