Abstract

The invention discloses a carbonyl metal complex high-pressure reaction kettle and an operation method thereof. The carbonyl metal complex high-pressure reaction kettle comprises a reaction kettle body and a driving mechanism; a solid material inlet and a slag outlet are formed in the shell of the reaction kettle body, so that continuous production is realized, and the production efficiency is improved; a material propelling and stirring mechanism is arranged in the reaction kettle, so that solid materials are mechanically stirred, a synthesis reaction is stably carried out, and the speed of the synthesis reaction is increased; a cooling water jacket is arranged on the outer wall of a reaction kettle, so that thermal decomposition of a reaction product carbonyl metal complex is prevented;by arranging the double cold-state shaft sealing mechanism at an end cover of the reaction kettle body, the leakage of carbon monoxide is avoided, and the erosion of carbonyl metal complex decomposermetal powder of a reaction product to a sealing structure is avoided. In conclusion, continuous production can be achieved, the service life of high-pressure reaction kettle equipment is prolonged, carbon monoxide gas leakage is avoided, the synthesis reaction is kept in a stable reaction state, and the production cost is reduced.

Description

technical field [0001] The present disclosure generally relates to the technical field of reactor devices, in particular to a metal carbonyl complex high-pressure reactor and an operation method thereof. Background technique [0002] Metal refining by the carbonyl method belongs to a metallurgical method for extracting metal powder in the field of gas phase metallurgy. This method uses carbon monoxide gas and raw materials containing active metals as reactants, and produces carbonyl metal complexes at a certain temperature and pressure. Metal carbonyl complexes are very unstable and can be rapidly decomposed into metal and carbon monoxide gas at a certain temperature (≥100°C). Metal powders can be obtained through separation technology, such as: nickel, iron, tungsten, molybdenum, cobalt, niobium, tantalum , vanadium, rhenium, manganese, thorium, hafnium, ruthenium, etc. The methods used in metal carbonyl synthesis reactions are generally divided into normal pressure method...
