The invention discloses a suspended
pickling exhaust filter
recovery device, which comprises an exhaust collecting cover arranged above a
pickling tank and a
cantilever crane arranged on the side of the
pickling tank, wherein the
cantilever crane is provided with an electric hoist connected with the exhaust collecting cover, the exhaust collecting cover is connected to a filter
tower through a first pipeline, one end of the first pipeline is disposed on the lower layer of the filter
tower, an induced draft fan is disposed on the first pipeline, alkali liquid and a pebbles
pile are arranged onthe lower layer of the filter
tower, a quicklime layer is arranged on the middle layer of the filter tower, the upper layer of the filter tower is hemispherical, the upper layer of the filter tower isconnected to the exhaust collecting cover through a second pipeline, the upper layer of the filter tower is connected to a
hydrogen compressor through a third pipeline, and the third pipeline is provided with a valve. The suspended pickling exhaust filter
recovery device can be used to recycle pickling exhaust, and pickling exhaust recycled and processed has the advantages of not endangering
human health, causing no explosion accident and recycling
hydrogen. The suspended pickling exhaust filter
recovery device also has the advantages of convenient operation for workers, long service life, high work efficiency and low maintenance frequency.
