Abstract

The invention belongs to the technical field of production of a high melting point rare metal and a high melting point scattered metal, in particular to a device for reducing metal rhenium and molybdenum through radiation dissociation of a rhenium and molybdenum gas electrode. The device comprises a rhenium and molybdenum gas smoke-eliminating and dust-removing system, a molybdenum gas smoke-eliminating and dust-removing system, a metal rhenium producing machine, a first metal molybdenum producing machine and a second metal molybdenum producing machine which are arranged at five different altitudes, and a room-temperature desulfurizing, denitrating and decarbonizing device, a direct current power supply and electrical appliance interlocker and an induced draft fan. In the running process, each container and a gas conveying pipeline system maintain a constant negative pressure intensity, and leakage and emission of heavy metal rhenium oxide gas, heavy metal molybdenum oxide gas and sulfur dioxide gas are avoided; the device overcomes the defect that the recycling rate of leaching metal rhenium powder from baking fume is low, directly produces metal rhenium Re(s) and metal molybdenum Mo(s) from sublimated and volatilized rhenium and molybdenum gas through identifying soft X rays, and completely recycles sulfur in molybdenite, thereby greatly reducing pollution of the sulfur dioxide to the environment.

Description

technical field [0001] The invention belongs to the technical field of producing high melting point rare metals and high melting point scattered metals, in particular to a device for reducing metal rhenium molybdenum with a rhenium gas molybdenum gas electrode by radiation dissociation. Background technique [0002] Metal molybdenum Mo(s) has a melting point of 2622°C, a low density of only 10.2, a small thermal expansion coefficient, and strong corrosion resistance. It is widely used in the smelting of high-speed steel, stainless steel, and special steel. It is used in navigation, aviation, and aerospace engine manufacturing. It has important applications in the field of military industry technology. Metal rhenium Re(s) has a higher melting point, as high as 3180°C, and a density of 21, which is about twice that of metal molybdenum Mo(s); compared with metal molybdenum Mo(s), metal rhenium Re(s) is more solid, The corrosion resistance is better, and the electrical resistiv...
