Description

Technical Field

[0001] The utility model relates to the field of condensation towers, in particular to a yellow phosphorus electric furnace series condensation tower. Background Art

[0002] The industrially applied electric furnace yellow phosphorus production process is divided into a production process using a large self-baking electrode phosphorus electric furnace and a production process using a multi-electrode phosphorus electric furnace. Although these two processes differ in terms of furnace type and scale, requirements for handling raw materials entering the furnace, and measures for dust removal of furnace gas, the main processes are basically the same, that is, a mixture of phosphate ore, silica and coke in proportion is fed into the electric furnace, and the mixture in the electric furnace undergoes a reduction reaction to generate furnace gas. The furnace gas overflows from the reaction melting zone, passes through the furnace gas filter layer formed by the continuously replenished mixture in the upper part of the furnace, and is discharged from the electric furnace carrying a portion of impurities in the mixture, and then undergoes dust removal, condensation washing, and refined separation to obtain the yellow phosphorus product.

[0003] During the yellow phosphorus production process, the exhaust gas generated by the electric furnace contains a large amount of phosphorus vapor. If this phosphorus vapor is directly discharged into the atmosphere without treatment, it will not only cause a waste of phosphorus resources, but also cause serious pollution to the environment.

[0004] When the exhaust gas containing a large amount of phosphorus vapor is treated in a series condensation tower, it is cooled and condensed by spraying water. Although the spraying water can play a certain flushing role, a part of the phosphorus vapor will be adsorbed on the inner wall of the condensation tower after condensation. The phosphorus-containing substances adsorbed on the inner wall will gradually accumulate and may form phosphorus deposits. The condensation tower needs to be disassembled and maintained regularly to remove the phosphorus deposits on the inner wall, which increases the labor of the staff. Therefore, a yellow phosphorus electric furnace series condensation tower is proposed to solve the above problems. Utility Model Content
