System and method for producing vanadium pentoxide

Abstract

The invention relates to a system and a method for producing vanadium pentoxide. The system is characterized in that a stirring container is arranged below a first feed bin; an upper part of the stirring container is communicated with a lime milk container by a pipe; the stirring container is communicated with a first filter press by a pipe; a first electric box furnace is arranged below the first filter press; a second feed bin is arranged below the first electric box furnace; an alkali liquor container is arranged below the second feed bin; a second filter press is arranged below the alkali liquor container; a collection tank is arranged below the second filter press; a third filter press is arranged below the collection tank; a work bin is arranged below the third filter press; a second electric box furnace is arranged below the work bin; the top of the collection tank is communicated with a sulfuric acid container by a pipe; and the top of the alkali liquor container is communicated with an alkali bin by a pipe. The method is simple. The system adopts the reasonable devices and is convenient for maintenance.

Description

technical field

[0001] The invention relates to a vanadium pentoxide production system and method, in particular to a vanadium pentoxide production system and method in the sponge titanium production process. Background technique

[0002] With the development and progress of titanium sponge production, its technology is becoming more and more mature, and the production system of vanadium pentoxide is also becoming more and more perfect.

[0003] However, in the actual production process, the vanadium pentoxide production technology is backward, and the remaining lime slag produced from the refined titanium tetrachloride section is not recycled, but directly disposed of, resulting in a waste of resources. Contents of the invention

[0004] The present invention provides a vanadium pentoxide production system and method in order to solve the above-mentioned technical problems. The purpose is to improve production efficiency, reduce waste of resources, reduce cost and failur...
