Description of drawings
Fig. 1 is the structural representation according to the system that utilizes the useless composition brass of Sweet natural gas reduction of the utility model embodiment.
Wherein, 1: the natural gas supply device; 2: Sweet natural gas output control valve group device; 3: conveyance assisting device; 4: smelting furnace; 5: emergency cutting off valve; 6: flame retardant coating; 7: voltate regulator.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is done into a detailed description.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, the utility model provides a kind of system that utilizes the useless composition brass of Sweet natural gas reduction, and natural gas supply device 1 is used for providing Sweet natural gas to smelting furnace 4; Sweet natural gas output control valve group device 2 is connected with natural gas supply device 1, is used for the output of the Sweet natural gas in the natural gas supply device 1; Conveyance assisting device 3, one ends are connected with Sweet natural gas output control valve group device 2, and the other end passes into the copper liquid in the smelting furnace 4, and the natural gas transport that is used for Sweet natural gas output control valve group device 2 is exported is to smelting furnace 4; Smelting furnace 4 is used for splendid attire useless composition brass copper liquid to be restored.Wherein, Sweet natural gas output control valve group device 2 comprises output channel and is set in turn in the first ball valve, strainer, emergency cutting off valve, voltate regulator, check valve, spark arrester and the second ball valve on the output channel.Strainer is used for filtering out foreign material and the moisture of Sweet natural gas, prevents that steam from splashing in stove; Emergency cutting off valve is connected to operation room by electric wire, meets the emergency situations emergency switching-off, prevents tempering; Voltate regulator is used for regulating gas pressure and flow, prevents that black smoke from producing; The function of check valve and spark arrester all is to prevent tempering.Simply say, Sweet natural gas output control valve group device 2 and conveyance assisting device 3 to the smelting furnace 4 that fills useless composition brass copper liquid to be restored, reduce the natural gas transport in the natural gas supply device 1 to useless composition brass copper liquid.Conveyance assisting device 3 can select pipe to be wrapped with the iron pipe of flame retardant coating 6.In the process of reduction, flame retardant coating 6 can prevent and avoid the useless composition brass copper liquid of high temperature for the damage of iron pipe 3.Sweet natural gas output control valve group device 2 and conveyance assisting device 3 adopt the design that removably connects, and have made things convenient for the replacing of conveyance assisting device 3.
The reduction of composition brass is not only cleaned, expense is low but also efficient is high to utilize Sweet natural gas to give up, and not have the reason of popularization at present mainly is to consider safety factors.The utility model utilization is arranged at emergency cutting off valve 5, check valve and the spark arrester on the output channel, prevents Sweet natural gas tempering in reduction process, runs into the situations such as pressure jump, air-supplying valve can be closed, and overcomes the potential safety hazard that the Sweet natural gas tempering causes.
System of the present utility model is used for the useless composition brass copper liquid of Sweet natural gas reduction, utilizes Sweet natural gas to replace the composition brass copper liquid reduction of give up of traditional log, has greatly improved the speed of reducing, and has improved the operating environment of stokehold.Because Sweet natural gas is the low price energy, expense also decreases than the employing round log, and has reduced the destruction to the forest reserves, has obtained the high unity of economic benefit, environmental benefit and social benefit.For example, reduction 100t smelts the useless composition brass copper liquid that contains oxygen 6000ppm in the open hearth, need to pass into Sweet natural gas with the pressure of 0.2MPa 40 minutes, approximately needs 500 cubic metres of Sweet natural gases.If use the round log reduction, approximately need round log 5m
3About, with 3 yuan/m of present Sweet natural gas
3With 1550 yuan/m of round log
3Adjust, use 6250 yuan of the rear every stove cost savings of Sweet natural gas reduction, namely unit costs descends about 60 yuan.
Round log is to insert from body of heater termination skimming gate in the actual mechanical process, and stove also will stay 2 meters to hang wireline outward, and long 8 meters of general 100 tons of stove bodies of heater can cause reduction inhomogeneous when therefore reducing with round log, affect copper cash base quality.When reducing with Sweet natural gas, can in stove, move by the manual operation iron pipe, so that can revert to Anywhere in the stove, so Sweet natural gas reduction good evenness can improve copper cash base quality.Therefore this system architecture is simple, easy and safe to operate, and reduction effect is good, and cost saving is convenient to promote.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
