According tothe melting furnace, combustion-supporting air is preheated by the aid of high-temperature flue gas, and the heat efficiency of the furnace is improved.

Description

technical field [0001] The invention belongs to the field of metallurgy, in particular to a regenerative combustion V 2 o 5 melting furnace. Background technique [0002] Vanadium is an important strategic resource in my country, mainly used in metallurgy, chemical industry, national defense industry, aerospace and other fields. At present, the main methods used in the melting of vanadium pentoxide in my country are "one-step method" and "three-step method" production methods. The "one-step" production method of vanadium pentoxide is the process of dehydrating, decomposing, and melting wet ammonium vanadate in a melting furnace. The "one-step" production method has low energy utilization rate, large heat loss from exhaust smoke, and poor production environment. , the disadvantage of large pollution. The "three-step" production method of vanadium pentoxide refers to the process of dehydration, decomposition and melting in three different equipment. Although the "three-ste...

The "one-step" production method of vanadium pentoxide is the process of dehydrating, decomposing, and melting wet ammonium vanadate in a melting furnace. The "one-step" production method has low energy utilization rate, large heat loss from exhaust smoke, and poor production environment. , the disadvantage of large pollution

The "three-step" production method of vanadium pentoxide refers to the process of dehydration, decomposition and melting in three different equipment. Although the "three-step" production method solves the problem of energy utilization, However, the equipment cost is high, the structure is complicated, it is not suitable for small-scale production, and it is difficult to be accepted by most enterprises.
