Abstract
The invention provides an argon purification device for sponge titanium production, which comprises a filter plate (3) arranged at the bottom in a reactor, a gas outlet pipe (1), a ventilation pipe (5) and a large cover (6) covered at the top end of the reactor. The gas inlet end (1.1) of the gas outlet pipe (1) is arranged below the filter plate (3), the gas outlet end (1.2) of the gas outlet pipe (1) is located on the side face of the top, the ventilation end (5.1) of the ventilation pipe (5) is located in the middle of the top surface of the large cover (6) of the reactor, and the inserting end (5.2) of the ventilation pipe (5) is located on the lower portion in the reactor. The argon purification device for the sponge titanium production has the advantages of (1) being capable of effectively reducing oxygen, nitrogen, carbon dioxide, moisture and other impurities in argon, and improving quality of sponge titanium indirectly; (2) being simple in structure, easy to operate, good in purification effect and the like.
Description
Technical field
The invention belongs to the non-ferrous metal metallurgy technical field, relate in particular to a kind of Titanium Sponge 40-60 mesh argon gas purifying unit that is used to produce.
Background technology
The magnesium reduction distillation method is produced Titanium Sponge 40-60 mesh, is in reactor drum, to generate Titanium Sponge 40-60 mesh with the magnesium reduction titanium tetrachloride under certain condition.And in process of production the Titanium Sponge 40-60 mesh under the condition of high temperature if contact with air, can and impurity generations such as nitrogen, oxygen other and the more difficult isolating impurity of Titanium Sponge 40-60 mesh, thereby have influence on the quality of Titanium Sponge 40-60 mesh.Use the method for argon gas normally to adopt the outsourcing liquid argon after evaporating, directly to be used in the Titanium Sponge 40-60 mesh production and produce Titanium Sponge 40-60 mesh at present, therefore in Titanium Sponge 40-60 mesh is produced, use argon gas directly to contact with air as the isolated Titanium Sponge 40-60 mesh of shielding gas.And argon gas directly contacts with Titanium Sponge 40-60 mesh as shielding gas, and impurity such as the oxygen in the argon gas, nitrogen, carbonic acid gas, steam can the Titanium Sponge 40-60 mesh reaction generate other impurity, have influence on the quality of Titanium Sponge 40-60 mesh.Therefore reduce that foreign matter content is a key factor that improves the sponge quality in the argon gas.
Summary of the invention
For addressing the above problem, the present invention realizes through following technical scheme.
A kind of argon gas purifying unit that is used for Titanium Sponge 40-60 mesh production, the present invention is characterised in that, comprises, is arranged on filter plate, escape pipe, permeability cell and the cap seal of the reactor drum inner bottom part big lid in reactor top; The inlet end of escape pipe places the below of filter plate, and the outlet side is positioned at the side at top; The ventilative end of permeability cell is positioned at the end face middle part of the big lid of reactor top, and insertion end is positioned at the bottom of reactor drum.
Apparatus of the present invention assemble by synoptic diagram, carry out stopping property detect qualified after, hang in after process furnace is heated to 800-850 ℃, argon gas gets into this device from inlet pipe and discharges from escape pipe through behind the scavenging material.
The principle of apparatus of the present invention purification of argon be based on scavenging material at 800-850 ℃ to the absorption of impurity such as the oxygen in the argon gas, nitrogen, carbonic acid gas, steam and the purification effect that reaches.
The present invention has following beneficial effect:
(1) the present invention can effectively reduce impurity such as oxygen in the argon gas, nitrogen, carbonic acid gas, steam, thereby has promoted the Titanium Sponge 40-60 mesh quality indirectly.
(2) to have a device structure simple, simple to operate in the present invention, characteristics such as good purification.
Attach: the contrast of this refining plant rear impurity content of argon gas process:
| Project | Index (%) before purifying | Purify back index (%) |
| Oxygen (O 2) content (volume(tric)fraction) | ≤0. 001 | ≤0.0007 |
| Nitrogen (N 2) content (volume(tric)fraction) | ≤0. 005 | ≤0.005 |
| Carbonic acid gas (CO 2) content (volume(tric)fraction) | ≤0. 001 | ≤0.0005 |
| Moisture (H 2O) content (volume(tric)fraction) | ≤0. 0015 | ≤0.0009 |
Can find out that through last table this argon gas purifying unit has tangible reduction effect to the foreign matter content in the argon gas.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Label among the figure: 1-escape pipe, 2-reactor drum, 3-filter plate, 4-scavenging material, 5-permeability cell, the big lid of 6-.
Specific embodiments
Below in conjunction with accompanying drawing novel the doing of the present invention further described.
As shown in Figure 1, a kind of argon gas purifying unit that is used for Titanium Sponge 40-60 mesh production, the present invention is characterised in that, comprises, is arranged on filter plate 3, escape pipe 1, permeability cell 5 and the cap seal of the reactor drum inner bottom part big lid 6 in reactor top; The inlet end 1.1 of escape pipe 1 places the below of filter plate 3, and outlet side 1.2 is positioned at the side at top; The ventilative end 5.1 of permeability cell 5 is positioned at the end face middle part of the big lid 6 of reactor top, and insertion end 5.2 is positioned at the bottom of reactor drum.
Filter plate as shown in fig. 1 is positioned in the reactor drum, then scavenging material 4 is positioned on the filter plate 3, and permeability cell 5 inserts in the scavenging material 4, and the inlet end of escape pipe 1 should be placed and filter plate 3 belows, and big lid 6 is gone up in assembling again.Assembling is accomplished after stopping property detects to hang in after qualified and is heated to 800-850 ℃ in the process furnace, and argon gas gets into this device from inlet pipe and discharges from escape pipe 3 and permeability cell 5 through purifying the back.
