Problems solved by technology

Its shortcoming is that this patent almost copied the technological process and production conditions of the Gulf Chemical Company in Freeport, Texas, the only difference is that the multi-hearth furnace is replaced by a rotary furnace, which is exactly the same as that of the Japanese Sun Company. Japan's environmental protection requires governance SO emissions 2 , the patent does not even have a management design

Embodiment 1

[0068] The actual measurement of the material balance listed in the above table was completed under the conditions of flash drying temperature of 200°C, ammonia decomposition furnace temperature of 500°C and flash furnace temperature of 700°C.

[0069] The above examples are the results of three groups of material balance measurements. With this three-step vanadium production method, not only the product recovery rate is as high as 99%, but the finished vanadium is increased by 6-7 percentage points, and the unit oil consumption is also lower than that of the reverberatory furnace refining flake vanadium. A ton of fuel oil.

[0070] The production of vanadium pentoxide from vanadium-containing wastes does not pay attention to the recovery of decomposed ammonia and water ammonium in the formulation of processes at home and abroad. The method adopted is to further decompose most of the decomposed ammonia into H 2 and N 2 A small part of high-altitude emissions. The pres...

Abstract

Extraction of vanadium and molybdenum from waste materials is carried out by physically or chemically pre-treating for raw materials by recovered oil, leaching out at a certain pH value, generating soluble sodium metavanadate and sodium molybdate, removing impurities, filtering, solid-liquid separating, precipitating ammonium metavanadate by amine salt, filtering, drying, decomposing, tabletting by smelting furnace to obtain sheeted vanadic anhydride, precipitating ammonium metavanadate filtrate, pouring it into vanadium extraction tank, extracting by organic phase, cleaning by saturated organic phase, reversed extracting, concentrating and crystallizing. It has better vanadium recovery rate and quality and more product yield.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of waste resources, in particular to comprehensively treat waste catalysts containing vanadium and molybdenum, steel slag containing vanadium, red mud, red cake, putty, furnace ash, etc., and extract valuable components, such as V 2 o 5 etc., specifically a method for extracting vanadium and molybdenum compounds from various waste materials containing vanadium and molybdenum. Background technique [0002] 1. Due to its physical and chemical properties, vanadium is widely used in various fields of national defense construction and economic construction. In the metallurgical industry, because vanadium can refine the crystal material, improve the heat resistance and strength of steel, it is often used in the production of stainless steel, Tank steel and high-strength structural steel, etc. In the petrochemical industry, it is mainly used as a catalyst for oil refining and sulfuric acid prod...
