This published patent document can effectively prevent gaps from occurring between the skin and the flange, making the expansion joint more tightly connected when connecting to high-temperature equipment in the soot pipeline. And after the air enters the interior of the skin, it is filtered three times by three filters before being discharged, so that impurities and ash in the air can be effectively filtered. Such a design adds an environmental protection function to the expansion joint and effectively improves the use effect of the expansion joint; however, in the above-mentioned published patent document, the connection component is used to connect the non-metallic expansion joint to two pipelines, and the connection component restricts the non-metallic expansion joint from tilting and does not have the function of compensating for the installation position, resulting in the inability to install and connect with two pipelines in different axial directions, and the installation flexibility is poor.
