Detailed Description

In accordance with the teachings of the present application, an embodiment of a purge gas reuse apparatus is provided herein with reference to the accompanying drawings. Referring to fig. 1 to 3, the purge gas recycling device includes an outer pipe 100 having a circular tube structure, a first end cap 110 and a second end cap 130 are respectively fixedly disposed at two ends of the outer pipe 100, and the first end cap 110 and the second end cap 130 are both hermetically connected to the outer pipe 100, wherein the first end cap 110 is disposed at an inner side of the second end cap 130, a certain gap is formed between the first end cap 110 and the second end cap 130, in addition, a first vent hole 120 for the purge gas to flow through is disposed on the first end cap 110, a second vent hole 140 communicated with the purge gas pipe 150 is disposed on the second end cap 130, the purge gas sequentially passes through the purge gas pipe 150, the second vent hole 140, the gap between the first end cap 110 and the second end cap 130, and the first vent hole 120, and finally flows into a cavity of the outer pipe 100, thereby achieving a purpose of heating the air in the heat exchange pipe 210.

The heat exchange assembly 200 includes a heat exchange pipe 210, a diverter tray 230, an inlet pipe 220, an outlet pipe 270, and first rotary blades 240. The plurality of heat exchange tubes 210 are uniformly arranged between the two diverter trays 230 and are communicated with the inner cavities of the diverter trays 230, the air inlet tube 220 and the air outlet tube 270 are symmetrically arranged at the outer sides of the two diverter trays 230 and are communicated with the inner cavities of the diverter trays 230, the air inlet tube 220 and the air outlet tube 270 are rotatably connected with the first end cover 110 and the second end cover 130, the first rotating blades 240 are fixedly connected to the air inlet tube 220 and the air outlet tube 270 respectively, the first rotating blades 240 are located between the first end cover 110 and the second end cover 130, and in order to prevent air leakage, the first end cover 110 and the second end cover 130 are in sealing connection with the air inlet tube 220 and the air outlet tube 270.

Specifically, the diverter tray 230 has a disc-shaped structure, and the diverter tray 230 has an inner cavity with a cylindrical structure, in which a bracket 260 is fixedly connected, and a second rotary blade 250 is rotatably connected to the bracket 260.

The during operation, be connected the outlet duct with the device that induced drafts, utilize the device that induced drafts to make the heat exchange tube form the negative pressure environment, external cold wind (for the hot-blast after the heating) is under the negative pressure effect, flow in by the intake pipe, the second rotating blade rotates under the effect of air current, make cold wind can be even enter into every heat exchange tube, the gas that bleeds directly blows on first rotating blade through the gas pipe that bleeds, and drive first rotating blade and rotate, thereby drive flow distribution disc and heat exchange tube and rotate wholly, the heat exchange tube is at the cavity internal rotation of outer pipeline, can make the heat exchange tube more abundant with the contact of the gas that bleeds, and the heat exchange efficiency. The device reduces the consumption of fire coal by the coal-fired hot-blast stove by recycling the purge gas, and realizes the purposes of energy conservation and emission reduction.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
