Technical discussion on blizzard filling tower
Thread Content
In the past, when filling fillers in factories, they usually hit the tower wall with a hammer to vibrate it to achieve a compaction effect. However, the filling of this filler is not good, and friction will still occur between the fillers, causing the fillers to rub out dust. I once found a method on the Internet that uses the German Carbotech company's storm filling technology. It can increase the filling volume by more than 5% on the basis of conventional filling. The fillings are tight and have no wear on each other. They can be used continuously for 8-10 years. This filling method has all the advantages. I wonder if anyone has come into contact with this technology. Please share it with me.
The filling materials you mentioned are too broad. For example, there are many types of fillers, including floc, granular powder, block, etc. The tightness of the added filler is not necessarily as close as possible, and the problem you are worried about is not that the tighter it is, the more likely it is to reduce friction. After all, the densities of the two substances are different. It is still necessary to analyze the specific situation and be targeted.
The so-called blizzard filling is not so mysterious. It is not the technology of a German company as promoted by some domestic manufacturers (this company was acquired by China Power Construction Group in 2018). Many companies in Japan and the United States have successively developed this pneumatic filling of adsorbents since the 1970s. The technology itself is nothing special. See screenshot: The real technical experience of this German company is actually its compression technology. It uses a special coconut pad material (known as fiber spring) to compress the filled adsorbent, which is unique. As for domestic copycats, see the picture below: In fact, they are very similar and the effect is pretty good. I don’t think this thing that is so mysterious is so big. Domestic manufacturers mostly promote PSA nitrogen manufacturers, so just listen to it. This type of pneumatic filling technology is generally used on adsorbents with a diameter of less than 2mm. Your random packing may not be suitable, so it is not necessary. . . I'm just afraid that it would be more reliable to use a hammer to vacuum.
Nazi crazy dogs are the best at bragging. He was so awesome, he wouldn't have been defeated twice and then pinned to the ground and beaten so hard that he covered his crotch, held his head, and screamed. :P
There are only two types, one is 4-6 mesh coconut shell activated carbon, and the other is φ3-5 molecular sieve. As long as the two fillers can be layered properly and not mixed, it will be fine.
I think the "copycat version" just uses compressed air to blow the filler in. The compressed air is only 5 bar. Can it be compacted?

It is impossible to compact this thing, it just relies on its own weight to fill in, which vibrates the shell. In addition, these two fillers do not require compaction. There are two types of concrete pump trucks, one is a trailer-type horizontal type, and the other is a long-arm concrete pump truck. This should work. They can be found in the area, usually on construction sites.
