the waste heat recovery heat exchange flow baffle comprises a circular flow baffle body, wherein the center of the flow baffle body is provided with a mounting ring, and the mounting ring is mounted on a heat exchange inner pipe;
the outer diameter of the flow baffle body is the same as the inner diameter of the heat exchange outer pipe, the edge of the flow baffle body is tightly attached to the inner wall of the heat exchange outer pipe, and the flow baffle body is perpendicular to the axial lead of the heat exchange outer pipe;
the flow baffle body is provided with a plurality of circulation channels, and the circulation channels are communicated with the windward side and the leeward side of the flow baffle body;
the spoiler body is provided with a plurality of spoilers on the windward side, and the spoilers are perpendicular to the windward side of the spoiler body.
Preferably, the spoiler is of an arc-shaped structure, the spoilers are sequentially and symmetrically arranged on the windward side of the spoiler body, one end of each spoiler is fixed on the mounting ring, and the other end of each spoiler points to the outer circumferential edge of the spoiler body and leaves a gap with the outer circumferential edge of the spoiler body.
Furthermore, the spoilers are spirally arranged on the windward side of the spoiler body, and the convex side of each spoiler is consistent in orientation.
Each circulation channel is arranged between two adjacent spoilers.
The outer circumferential edge of the flow baffle body is also provided with a flange, and the flange is positioned on the windward side of the flow baffle body.
The utility model provides a waste heat recovery heat exchange fender board through set up the spoiler on single fender board, need not increase the density that keeps off the board, consequently can not increase the equipment fixing degree of difficulty.
Drawings
