Problems solved by technology

In this process, zirconium tetrachloride will come into contact with the air, which will produce deliquescence and consume part of zirconium tetrachloride, and deliquescence will produce waste of zirconium tetrachloride; in addition, there are also low efficiency of zirconium sponge reduction and poor reduction reaction efficiency. Defects
In production, zirconium tetrachloride and magnesium are placed in the zirconium tetrachloride reaction furnace and the reduction furnace respectively. The purified zirconium tetrachloride is gaseous, and the metal magnesium in the reduction furnace is liquid. The reduction furnace is connected, and the gaseous zirconium tetrachloride enters the reduction furnace equipped with liquid magnesium for reduction reaction to make zirconium sponge, but the efficiency is low and the quality of the sponge produced is low

Embodiment 1

[0039] like Figure 1-2 As shown, a production equipment for zirconium sponge is provided in this embodiment, including a sublimation furnace 30 and a first reduction furnace 10 with a channel 20 on the top, and the channel 20 provided on the top connects the sublimation furnace 30 and the first reduction furnace 10 to each other In order to be able to adjust and control the intake of gaseous zirconium tetrachloride at any time, a first check valve 50 is provided on the channel 20, and the sublimation furnace 30 can heat and purify the zirconium tetrachloride therein, and the purified tetrachloride Zirconium oxide is in a gaseous state, and metallic magnesium in the first reduction furnace 10 is heated to a liquid state. like image 3 and 4 As shown, zirconium tetrachloride is purified in the sublimation furnace 30. One way is to set a condensation furnace 60 above the sublimation furnace 30 to purify the crude zirconium tetrachloride into high-purity zirconium tetrachloride...

Embodiment 2

[0049] This embodiment has been further improved on the basis of Embodiment 1, the difference is: as Image 6 As shown, in the production equipment for zirconium sponge provided in this embodiment, a trachea branch is provided between the intake pipe 107 and the second check valve 108, and a third check valve 117 and an explosive body 118 are provided on the trachea branch. There are several explosive bodies 118 stored in the storage box 116, and the air pump 109 first utilizes the negative pressure to suck the explosive bodies 118 into the branch circuit, and then uses the positive pressure generated to press the explosive bodies 118 into the intake pipe 107 And in the gas explosion tube 104, the explosive body 118 is ejected from the bottom of the gas explosion tube 104 by the pressure of argon and explodes in the magnesium liquid in the furnace 115. In this example, if Figure 7 As shown, the explosive body 118 is set to a spherical structure, the outer shell of the explos...

Embodiment 3

[0057] On the basis of Embodiment 1 and 2, further improvement has been carried out in this embodiment, the difference is: as Figure 8 and 9 As shown, a first reduction furnace 10 and a second reduction furnace 40 are connected with a sublimation furnace 30 through a channel 20. The first reduction furnace 10 and the second reduction furnace 40 have the same structure, and this structure expands the production capacity. times, if the consumption of 2400kg of zirconium tetrachloride requires two furnaces to react 1200kg of zirconium tetrachloride and 400kg of magnesium, the total deliquescence of about 200kg of zirconium tetrachloride is calculated, and the sublimation furnace with 2400kg of zirconium tetrachloride is connected Two reduction furnaces with 400kg of liquid magnesium, the deliquescence is reduced to 100kg, which is the same as the waste of 1200kg of zirconium tetrachloride, which saves raw materials; compared with the single consumption of 1200kg of zirconium tet...

Abstract

The invention relates to the technical field of metal smelting, in particular to production equipment and process of zirconium sponge. The production equipment of zirconium sponge comprises a channelfor connecting a sublimation furnace with a first reduction furnace, wherein molten liquid magnesium is placed in a furnace pipe, a furnace cover is provided with a magnesium feeding port, a liquid magnesium outlet, a temperature and pressure measuring device, inert gas supply equipment and a gas inlet pipe connected in a sealed mode, the gas inlet pipe is provided with a gas pump and a second one-way valve, a gas explosion pipe is arranged on the lower side of the gas inlet pipe, a gas pipe branch is arranged between the gas inlet pipe and the second one-way valve, a third one-way valve and astorage box for providing an explosion body are arranged on the gas pipe branch, and the explosion body is ejected out from the bottom of the gas explosion pipe by pressure of inert gas and explodesin magnesium liquid in the furnace pipe to accelerate reduction reaction. The production efficiency and quality of the zirconium sponge are improved, and good economic benefits and social benefits areachieved.

Description

technical field [0001] The invention belongs to the technical field of metal smelting, and in particular relates to production equipment and technology of zirconium sponge. Background technique [0002] Sponge zirconium, also known as metal zirconium, is a silver-gray metal with a steel-like appearance and luster. It has very strong corrosion resistance and ultra-high hardness and strength. It is mainly used in aerospace, military, nuclear reactions, etc. At present, the production of sponge zirconium mainly includes two steps: the first step is to purify zirconium tetrachloride, remove impurities in crude zirconium tetrachloride, and purify zirconium tetrachloride; The production of zirconium is carried out by reduction reaction, that is, the zirconium tetrachloride after reduction and purification reacts with magnesium to produce zirconium sponge. In this process, zirconium tetrachloride will come into contact with the air, which will produce deliquescence and consume par...
