How to handle dust from the chimney of catalytic devices
Thread Content
Dust from catalytic device chimneys directly causes air dust pollution! 1. Soot blowing in waste heat boilers; 2. Dust generated by the swirls ahead of the smoke extractor, which is usually discharged from the chimney from time to time; 3. A small amount of dust emitted by the chimney under normal conditions. Please share your respective methods of dealing with this issue! Thank you all first! !
Handling points 1 and 3 of yours is a bit difficult. 2 pieces are not allowed; they should normally be returned to the waste catalyst tank ；
Under normal circumstances, there is a small amount of emissions, but the spent catalysts located below the three spinners generally need to be placed in a tank for spent catalysts. It’s difficult to recover the heat from behind the waste heat boilers. In foreign refineries, electronic dust removal systems are used, as environmental regulations there are quite strict. In China, as long as the emissions are within acceptable limits or proper care is taken when inspection teams arrive, it’s sufficient to meet the requirements.
Yeah, we need to find a way to solve this! It can’t continue to harm the residents in the area!!:L
The catalyst fine powder from the three-spinning fine-powder tank is difficult to handle once it is collected in the waste catalyst tank; dust disperses everywhere during bagging. If environmental regulations in your area are not strict, it is possible to discharge this powder directly through the chimney at night when there is wind. When there is no wind, care must be taken to ensure that the dust does not fall in the surrounding area.
That’s why I want to gather everyone’s ideas to find the best way to solve the problem!!:L
The critical nozzles, the four rows of ash discharge lines lead directly to the chimney, and the ash from the waste heat furnace is discharged directly as well; in short, everything is released directly into the atmosphere!
