The natural gas reduction device for refining the waste impure copper guarantees the homogenization of mixed gas, increases the contact area of natural gas and copper liquid, reasonably controls the flow of the natural gas, and enables the reduction of the natural gas to achieve more efficient, economical and environment-friendly effects.
Description
Technical field
The utility model relates to copper smelting reducing field, relates in particular to the Sweet natural gas reducing apparatus for useless composition brass refining.
Background technology
During the useless composition brass of reflection open-hearth, with Sweet natural gas, replace traditional reductive agent (fresh trees, heavy oil etc.), really there is the advantage of economic environmental protection.Blast at present the device of Sweet natural gas, what only adopt is the oxidation oxygen lance in period.On the one hand, because the contact area of Sweet natural gas and copper liquid is limited, make reaction efficiency low, still can produce a large amount of black smokes; On the other hand, during natural gas pyrolysis, produced in a large amount of hydrogen remaining copper liquid, also can affect the quality of final FRHC copper bar, in addition Sweet natural gas reducing process needs nitrating gas, water mixing steam etc. now, and as can be seen here, this easy device is not suitable for new Sweet natural gas reducing process.
Utility model content
The purpose of this utility model is to provide a kind of nitrating gas, water mixing steam, pressure is adjustable and efficiently for the Sweet natural gas reducing apparatus of useless composition brass refining.
This Sweet natural gas reducing apparatus for useless composition brass refining that the utility model provides, comprise uniforming device, moccasin pipe and inlet pipe, described uniforming device comprises water vapor import, Imported gas, nitrogen inlet and gas outlet, described moccasin pipe one end is connected with the gas outlet of described uniforming device, one end is connected with the inlet end of inlet pipe, has some group holes of giving vent to anger on the tube wall of described inlet pipe outlet side.
For making the Sweet natural gas can be more abundant with reacting of nitrogen and water vapor, agitator is also installed on described uniforming device, described water vapor import, Imported gas and nitrogen inlet are connected with the inlet end of agitator respectively, and the outlet side of described agitator is connected with gas outlet.
For adapting to the difference of different process stage to natural gas demand, reduce the formation of black smoke, realize nitrogen, water vapor and Sweet natural gas and formed the effect that is equivalent to artificial fresh trees, the variable valve of controlling gas discharge is installed on described gas outlet.
For extending the work-ing life of inlet pipe, reduce production costs, described inlet pipe adopts heat-and corrosion-resistant alloy steel pipe.
Compared with prior art, the utlity model has following advantage:
1, the utility model makes the mixed gas homogenizing of nitrogen, water vapor and Sweet natural gas by uniforming device, due to nitrogen not only can with hydrogen reaction, generate the ammonia of highly volatile, thereby can reduce the content of hydrogen in copper liquid, can also strengthen the stirring of copper liquid, be conducive to copper liquid homogenization of composition; Water vapor bubble vapour pressure is lower, sulfurous gas in copper liquid is had to adsorption, nitrogen and water vapor have dividing potential drop effect in mixed gas in addition, when guaranteeing that Sweet natural gas has enough pressure to enter copper liquid, also can reduce concentration of natural gas to zone of reasonableness, Sweet natural gas is reacted completely as far as possible.
2, uniforming device of the present utility model is connected with moccasin pipe with inlet pipe, has guaranteed the handiness of inlet pipe operation.
3, the utility model is opened some group holes of giving vent to anger on the tube wall of inlet pipe outlet side, can make Sweet natural gas mixed gas with the form ejection of emitting shape, has increased the contact area with copper liquid.
The utility model has guaranteed the homogenizing of mixed gas, has increased the contact area of Sweet natural gas and copper liquid, and gas discharge is rationalized to control, makes more efficient, economy of Sweet natural gas when reduction, environmental protection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As can be seen from Figure 1, this Sweet natural gas reducing apparatus for useless composition brass refining of the utility model, comprise uniforming device 1, moccasin pipe 2 and inlet pipe 3, wherein uniforming device 1 comprises water vapor import 11, Imported gas 12, nitrogen inlet 13 and gas outlet 14, moccasin pipe 2 one end are connected with the gas outlet 14 of uniforming device 1, one end is connected with the inlet end of inlet pipe 3, has some group holes 31 of giving vent to anger on the tube wall of inlet pipe 3 outlet sides.
From Fig. 1, it can also be seen that, agitator 15 is also installed on the utility model uniforming device 1, the variable valve 16 of controlling gas discharge is installed on gas outlet 14, water vapor import 11, Imported gas 12 and nitrogen inlet 13 are connected with the inlet end of agitator 15 respectively, the outlet side of agitator 15 is connected with gas outlet 14 by variable valve 16.
In the utility model, inlet pipe 3 adopts heat-and corrosion-resistant alloy steel pipe.
Use procedure of the present utility model is as follows:
1, the generating unit of nitrogen, water vapor and Sweet natural gas is accessed respectively to nitrogen inlet 13, water vapor import 11 and Imported gas 12, now variable valve 16 is in closing condition.
2, moccasin pipe 2 one end are connected with the gas outlet 14 of uniforming device 1, one end is connected with the inlet end of inlet pipe 3, opens variable valve 16, and total pressure is controlled at 0.4～0.5Mpa, and first ventilates for some time, to the interior residual air of inlet pipe 3 is got rid of.
3, the outlet side of inlet pipe 3 is inserted in copper liquid, start to carry out restoring operation, propelling along with the time, copper liquid oxygen level reduces gradually, the amount of natural gas needing reduces, now turn down variable valve 16, make total pressure be controlled at 0.3～0.4Mpa, and the dividing potential drop of nitrogen, water vapor and Sweet natural gas can regulate by generating unit separately.
4, after end to be restored, extract inlet pipe 3, close variable valve 16, separate moccasin pipe 2 and inlet pipe 3.
