What I see is a phalaenopsis that is desiccated, probably due to a poor root system, that had been ravaged by insects, bacteria and fungi.
If nothing else, you need to understand that orchids, in general, do their respiratory gas exchange through their roots, rather than their leaves, as is the case for terrestrial plants.
The potting medium needs to retain moisture, but must also remain open and airy, so those exchange processes are not stifled, which leads to suffocation and death, giving the plant no way to take up water.
