The phenomenon of soot spraying of nitrogen generators is also called carbon molecular sieve pulverization, which occurs because the carbon molecular sieve is not tightly pressed or the carbon molecular sieve is loose.
Structural faults of the adsorption tower caused by impact or equipment movement during the use of the nitrogen generator, such as the desoldering of the adsorption tower pipeline, the outflow of the carbon molecular sieve, and the looseness and pulverization of the carbon molecular sieve. The substances ejected from the muffler generally have small particles, and we need to check whether the particles are activated carbon or molecular sieves. Because activated carbon and molecular sieve are black solid particles, it is difficult to distinguish from the color, but their particle shapes are different. If activated carbon is sprayed out, then the problem is not very serious. We can remove the activated carbon filter, remove the activated carbon inside, and check whether the wire mesh at the bottom of the activated carbon is damaged. If it is damaged, replace it with a new stainless steel wire mesh and install it. Return to activated carbon to operate normally. When filling activated carbon, try to fill the filter as much as possible to prevent the activated carbon from colliding with each other under the action of airflow to generate dust. If molecular sieve is sprayed out, it will be more troublesome to handle, and the equipment needs to be transported back to the factory for overhaul.
