Replacement of adsorbent in small PSA adsorption tower
Thread Content
This post was last edited by Ameba on 2016-12-2 15:34. For help, which sea user has experience in replacing the adsorbent of a small adsorption tower? Single tower diameter ~600mm, height ~6000mm, no hand holes, only upper and lower air inlets, flange DN150~~Please help, thank you~~
Sofa, thank you very much~~haha~~
Since adsorption towers generally cannot be equipped with discharge holes, large-capacity adsorption towers can be vacuumed out by companies that specialize in filling catalysts and adsorbents. For a small one, the easiest way is to lift it up with a crane and pour it out in reverse.
I have considered this option, but it is too troublesome. Do you have similar experience? Thank you very much for the help in unloading and loading.~~
Do you have a vacuum pump in your factory? Add a separation tank in front of the vacuum pump, lead the pipe to the top of the tower and connect it to a vacuum-resistant armored hose to extract the adsorbent in the adsorption tower. Store it in the separation tank first and then unload it. The purpose of the separation tank is to store and maintain vacuum.
Take it out? Pay attention to whether the adsorbent is strong enough. If the powdering is too severe, it will be difficult to handle.
Vacuum pump, with a screen below to filter and pulverize
Look out from the lower air inlet. You probably don’t have a screen.
The diameter is 600 and the length is 6 meters. It can only be pumped with a vacuum pump from above. The premise is that the adsorbent does not clump. In fact, it can be pumped even if it clumps and breaks. At this height, it can be pumped with more power. It will definitely not work if there is a filter.
Intake air from the upper port and exhaust air from the lower port (and discharge the adsorbent). The adsorbent is brought out by gas pressure. Just purge it several times. Similar to blasting and purging
