Gas dryer system

A gas dryer system (1) comprising: a plurality of gas dryers (2); a collection exhaust pipe (30) connected to each of the plurality of gas dryers (2) via an exhaust pipe (10); a filter device (50) connected to the collection exhaust pipe (30) and having a water surface on which exhaust gas supplied from the collection exhaust pipe (30) collides; the air speed switching unit is used for switching the air speed of the exhaust gas colliding with the water surface; the system can remove dust contained in exhaust gas passing through an integrated exhaust pipe connected with a plurality of gas dryers, and can ensure that the dust in the exhaust gas can be fully and effectively removed even if the exhaust gas flow of the integrated exhaust pipe changes. 一种燃气烘干机系统(1)，包括：多个燃气烘干机(2)；集合排气管(30)，经由排气管(10)分别与多个燃气烘干机(2)连接；过滤装置(50)，与集合排气管(30)连接，具有供从集合排气管(30)供给来的排气碰撞的水面；以及风速切换单元，用于切换与水面碰撞的排气的风速；该系统可以去除通过多个燃气烘干机所连接的集合排气管的排气所含的尘埃，并且即使在集合排气管的排气流量发生变化时，也能确保排气中的尘埃得以充分有效去除。
