Problems solved by technology
Heating methods include electric heating, fuel oil, gas, coal combustion, and hot air circulation. The annealing furnace is a new type of heat exchange equipment. The gas after heat exchange in the annealing furnace contains a large amount of hydrogen gas, which is a waste of resources when it is directly discharged, and hydrogen is flammable. Explosive gas, the mixture of hydrogen and air will explode if it exceeds a certain range, which will bring serious hidden dangers to the production safety of the factory
[0003] In the prior art, no more than 2% of the volume of impurities are mixed into the tail gas of the continuous hot-dip galvanizing annealing furnace: the impurities are mainly dust, oil, oxygen, water, and nitrogen, and these impurities cannot be effectively removed, resulting in the inability to recycle hydrogen , resulting in waste and danger-prone problems
For the above-mentioned problems, no effective solutions have been proposed so far

The invention discloses a hydrogen recovery device of a continuous hot galvanizing annealing furnace, and relates to the technical field of hydrogen recovery devices. The hydrogen recovery device of the continuous hot-dip galvanizing annealing furnace comprises the continuous hot-dip galvanizing annealing furnace and a hydrogen recovery device, the tail gas exhaust port is formed in one side of the continuous hot galvanizing annealing furnace; the multi-stage cooling device is communicated with the tail gas exhaust port through a first pipeline; the dust removal filter is communicated with an outlet of the multi-stage cooling device through a second pipeline; the oil removal filter is communicated with an outlet of the dust removal filter through a third pipeline; and the separation device is communicated with the oil removal device through a fourth pipeline and is used for completely separating oxygen and water. The continuous hot galvanizing annealing furnace tail gas purification device solves the problems that in the prior art, no more than 2% by volume of impurity components are mixed into continuous hot galvanizing annealing furnace tail gas, impurities mainly include dust, oil dirt, oxygen, water and nitrogen, the impurities cannot be effectively removed, hydrogen cannot be recycled, waste is caused, and danger is likely to happen.
Description
technical field [0001] The invention relates to the technical field of hydrogen recovery devices, in particular to a hydrogen recovery device for a continuous hot-dip galvanizing annealing furnace. Background technique [0002] Heat treatment furnaces are divided into annealing furnaces, quenching furnaces, tempering furnaces, normalizing furnaces, and quenching and tempering furnaces. They are mainly used for annealing of large carbon steel and alloy steel parts; tempering of surface quenched parts; heat treatment processes such as stress relief annealing and aging of weldments. Heating methods include electric heating, fuel oil, gas, coal combustion, and hot air circulation. The annealing furnace is a new type of heat exchange equipment. The gas after heat exchange in the annealing furnace contains a large amount of hydrogen gas, which is a waste of resources to be discharged directly, and hydrogen is flammable. Explosive gas, the mixture of hydrogen and air will explode i...
