Abstract

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.

Description

technical field [0001] The invention belongs to the field of recovery and treatment of pickling waste gas, and in particular relates to a suspension type pickling waste gas filtration and recovery device. Background technique [0002] Pickling exhaust gas refers to the exhaust gas generated when rusty parts are pickled and derusted by pickling process. The acid solution used for pickling contains a large amount of HCl, and HCl reacts with rust to eliminate rust. At the same time, HCl will also react with iron to generate hydrogen gas, and hydrogen gas overflows to impact the rust, causing the rust to peel off quickly and speed up rust removal. Since HCl itself is a volatile gas, the volatilization of HCl will be accelerated during the process of hydrogen overflow, so there are often high concentrations of HCl and hydrogen in the pickling place. HCl is toxic and will endanger human health. Hydrogen accumulates in the air. After a certain concentration, it will explode in ca...
