Problems solved by technology

[0004]Because there is a small amount of sulfuric acid mist in the air dried by sulfuric acid, the acid mist enters the air compressor, which can easily cause corrosion of parts in the air compressor, damage, resulting in unstable system operation and high maintenance costs

Description

technical field [0001] The present invention relates to a P 2 o 5 A phosphorus burning atomization system and an atomization process in the production process belong to the field of chemical equipment. Background technique [0002] Domestic traditional phosphorus pentoxide (P 2 o 5 ) production method is to use the self-flowing method of yellow phosphorus to burn in the phosphorus-burning furnace. This way of feeding phosphorus causes the yellow phosphorus to not fully contact with the air and cannot be fully burned. The amount of air intake and phosphorus intake is difficult to control, which will make the acid The output of yellowing and phosphorus pentoxide is low, the product quality cannot be guaranteed, and the production efficiency is low. [0003] In order to reduce the corrosion of the equipment of the phosphorus-burning furnace and cooling tower by the high-temperature combustion flue gas generated by the humid air, and further improve the product quality, it i...
