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 a fluid control device, in particular to a radial gas rectifier, belonging to the technical field of fluid flow control equipment. Background technique [0002] Traditional gas rectifiers are divided into two types, plate-shaped and sheet-shaped. These two types of rectifiers are widely used to divert gas, eliminate vortices, and adjust velocity distribution; however, most of the current gas rectifiers are shafts designed for round or square pipes. Toward rectifiers, there are fewer gas rectifiers for annular or square-cavity pipes, especially for the cavity with a small distance between the inner and outer cavity surfaces. 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. On the other hand, most of them are not traditional axial air intake methods, but one or more Air intake in the radial direction. This one or ...
