Ours is a spray tower; I’m not aware of its advantages, but the downside is that it gets clogged easily

1. In terms of structure, hydrogen scrubbers come in two types: those with packing and those that are packed-free. Since hydrogen contains a significant amount of alkaline mist, the principle for selecting a scrubber tower is as follows: a tower with good water quality, no hardness, and sufficient gas flow rate can utilize a packed tower. For normal water quality with hardness, it is still recommended to use an empty tower. 2 In terms of the method of supplying washing water, there are two types: single-use washing and recycled washing. One-time washing is the most common method; cooling water is sprayed from the top of the tower and discharged from the water seal tank at the bottom of the tower. Circulating washing operates in a manner similar to a chlorine water scrubber tower: pure water is first introduced into the scrubber tower, and a pump is used to circulate this water in order to cool the hydrogen gas. A plate heat exchanger is installed at the pump outlet to remove the heat released by the hydrogen gas. The water carried by the hydrogen gas is discharged through the valve at the pump outlet and sent to the brine processing stage. It is equivalent to the circulating water indirectly cooling the hydrogen. Given the increasing strain on water resources and the need for cleaner production, the second method is increasingly becoming the mainstream process.
We manufacture them ourselves; the material is carbon steel. There is filler inside. Cooling water is sprayed from the top of the tower, and a pump is used to circulate this water in order to cool the hydrogen gas, with a plate heat exchanger installed at the pump outlet.
