Description

Technical Field

[0001] The utility model relates to a metering device, in particular to a ferroalloy smelting carbon emission metering device, belonging to the technical field of ferroalloy smelting. Background Art

[0002] Metals are usually extracted from ores through smelting processes. In the smelting process, heat and chemical reducing agents (i.e., reducing agents) together reduce the metal oxides in the ore. Carbon dioxide gas is produced during ferroalloy smelting. The carbon dioxide emitted by ferroalloy smelting requires the use of a metering and detection device. The metering device refers to the measurement of the emitted carbon dioxide, that is, the measurement of carbon emissions; carbon emissions are a general term or abbreviation for greenhouse gas emissions. The most important gas in greenhouse gases is carbon dioxide, so carbon is used to represent greenhouse gases. Greenhouse gas emissions are generally considered to be the main cause of global warming, so low-carbon life is quietly emerging, and the most important thing is to limit carbon emissions, especially for industrial production such as ferroalloy smelting. In the process of limiting carbon emissions, a carbon emission metering device is needed to measure emissions.

[0003] In the prior art, a carbon emission metering device for ferroalloy smelting is disclosed in announcement number CN219201574U, comprising a shell, one side of the shell is movably connected with a hinge, the other side of the hinge is movably connected with an outer cover, one side of the outer cover is fixedly installed with a hook, one side of the shell is fixedly installed with a buckle, one side of the shell is provided with an air inlet, one end of the air inlet is movably connected with a suction fan, and one side of the suction fan is provided with a delivery pipe; this ferroalloy smelting carbon emission metering device, through the setting of the air inlet pipe and the filter net, a lot of dust or fine particles will remain in the exhausted gas. If they are not handled in time, the tested measurement will produce errors, and the setting of the filter net can be used to control the inside of the air inlet pipe. The gas is filtered to reduce the dust and some impurities carried in the exhaust gas to prevent it from affecting the detection and measurement effect. This setting can detect and measure more accurately without causing errors. In the prior art, there is also a filtration for the exhausted gas, but because a single filter is used for filtration, if the filter mesh is large, it cannot have a good filtering effect, but if the filter mesh is small, long-term use will cause the filter mesh to be easily blocked, thereby affecting the smooth flow of gas. Secondly, although the prior art is provided with a heat sink and heat dissipation holes, it is not able to dissipate the heat of the exhaust gas. Since the exhaust gas carries more heat, that is, the temperature of the exhaust gas is high, long-term use is likely to cause damage to the metering detection end of the metering equipment.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Embodiment 1

[0033] like Figure 1 and Figure 3 As shown, a carbon emission metering device for ferroalloy smelting includes a butt-joint pipe 1 and a metering instrument body 6. The butt-joint pipe 1 is connected to the exhaust pipe of the ferroalloy smelting equipment, and the metering instrument body 6 is installed on the pipe wall of the butt-joint pipe 1;

[0034] The pipe wall of the butt-joint pipe 1 is connected with an L-shaped connecting pipe 2, and the horizontal end port of the L-shaped connecting pipe 2 is aligned with the flow direction of the exhaust gas in the butt-joint pipe 1. A filter cartridge 3 and a delivery pipe 5 are arranged on the outside of the butt-joint pipe 1. The metering detection end of the metering instrument body 6 is inserted in the delivery pipe 5. A filter cartridge 3 is arranged between the delivery pipe 5 and the L-shaped connecting pipe 2. A spiral cold water pipe 35 is also installed in the filter cartridge 3. The metering instrument body 6 can adopt the metering valve meter disclosed in the announcement number CN219201574U.

[0035] The filter cartridge 3 provided can filter out dust and other impurities in the exhaust gas to avoid the presence of dust and other impurities affecting the accuracy of carbon emission measurement and detection. The spiral cold water pipe 35 provided can take away the transferred heat in the exhaust gas to ensure that when carbon emission measurement and detection is performed through the metering instrument body 6, inaccurate detection will not be caused by the high gas temperature, and damage to the metering and detection end of the metering instrument body 6 will be avoided.

[0036] Embodiment 2

[0037] Improvements based on Example 1:

[0038] like Figures 1 to 6 As shown, both ends of the butt-joint pipe 1 are integrally connected with a butt flange 11, which can be connected to the exhaust pipe of the ferroalloy smelting equipment through the butt flange 11, so that the metering device can be easily installed together with the ferroalloy smelting equipment to realize the metering of carbon emissions in the ferroalloy smelting process.

[0039] Furthermore, the vertical end of the L-shaped connecting pipe 2 passes through one side wall of the butt-jointed pipe 1, and a threaded ring is provided at the vertical end of the L-shaped connecting pipe 2. The vertical end of the L-shaped connecting pipe 2 is threadedly connected to two locking nuts 21, and the locking nuts 21 are respectively locked and clamped on the inner and outer sides of one side wall of the butt-jointed pipe 1, so that the L-shaped connecting pipe 2 and the butt-jointed pipe 1 can be combined and connected together, and the length of the vertical end of the L-shaped connecting pipe 2 extending out of the side wall of the butt-jointed pipe 1 can be adjusted by adjusting the positions of the two locking nuts 21, so that the horizontal end of the L-shaped connecting pipe 2 can be located at different positions inside the butt-jointed pipe 1, that is, by measuring and detecting carbon emissions at multiple different positions, the detection accuracy is improved.

[0040] Furthermore, the vertical end of the L-shaped connecting pipe 2 is also sleeved with a lower pad 22 and an upper pad 23, the upper end surface of the lower pad 22 is an inwardly concave arc surface, and the lower end surface of the upper pad 23 is an outwardly convex arc surface, and the upper end surface of the lower pad 22 and the lower end surface of the upper pad 23 are both integrally connected with a sealing ring 24, so that the lower pad 22 can be fitted together with the outer wall of the butt joint 1, and the upper pad 23 can be fitted together with the inner wall of the butt joint 1, thereby ensuring that the connection between the L-shaped connecting pipe 2 and the butt joint 1 is sealed, and when the two locking nuts 21 are tightened, the lower pad 22 and the upper pad 23 can be squeezed, so that the sealing ring 24 is tightly attached to the gap at the connection between the L-shaped connecting pipe 2 and the butt joint 1, which can ensure a tighter seal and prevent the exhaust gas from overflowing.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, a tube cover 32 is also provided on the outside of the tube body of the butt-joint tube 1, and a connecting rod 31 is connected to the center of the tube cover 32, and the other end of the connecting rod 31 is fixedly connected to the outer wall of the tube body of the butt-joint tube 1, and the inner cavity of the filter cartridge 3 contains a polar solvent, and the upper end of the filter cartridge 3 is threadedly sealed with the tube cover 32, and the tube cover 32 is penetrated and connected with an air inlet pipe 38, and the air inlet pipe 38 is connected with the L-shaped connecting pipe 2, and the air inlet pipe 38 is inserted at the bottom of the inner cavity of the filter cartridge 3, and the polar solvent includes but is not limited to industrial alcohol. Since the exhaust gas discharged contains a large amount of dust and other debris, the dust and other debris can be separated from the gas components in the exhaust gas by first passing the exhaust gas into the filtrate, so as to realize the filtration of the exhaust gas, and the carbon emission measurement is mainly for the measurement of the carbon dioxide content in the exhaust gas, and carbon dioxide is a non-polar molecule. According to the polarity compatibility principle, gaseous carbon dioxide will not dissolve in polar solvents, so when the exhaust gas is filtered by a polar solvent, it will not cause a decrease in the carbon dioxide content, and thus will not affect the accuracy of the measurement and detection.

[0042] Furthermore, a telescopic tube 33 is arranged between the air intake pipe 38 and the L-shaped connecting pipe 2. The bottom end of the telescopic tube 33 is connected to the air intake pipe 38. The upper end of the telescopic tube 33 is connected to a docking joint 34. The docking joint 34 is threadedly and sealedly connected to the vertical end of the L-shaped connecting pipe 2, which can ensure that when the installation position of the L-shaped connecting pipe 2 is adjusted, the length of the telescopic tube 33 can be expanded and contracted accordingly.

[0043] Furthermore, the bottom end of the filter cartridge 3 is connected to a water inlet joint 36, the cylinder wall of the filter cartridge 3 is connected to a water outlet joint 37, and the water outlet joint 37 and the water inlet joint 36 are respectively connected to the upper and lower ends of the spiral cold water pipe 35. Since the exhaust gas discharged from ferroalloy smelting contains more heat, when the exhaust gas is passed into the polar solvent, the exhaust gas can be filtered while the gas components in the exhaust gas can be cooled. Cold water is transported to the spiral cold water pipe 35 through the inlet and outlet water joints to cool the polar solvent, that is, the transferred heat in the exhaust gas can be taken away, so as to ensure that when the carbon emission metering detection is performed through the metering instrument body 6, the detection will not be inaccurate due to the high gas temperature, and to avoid damage to the metering detection end of the metering instrument body 6.

[0044] like Figure 1 , Figure 8 , Fig. 9 and Fig.10 As shown, one end of the conveying pipe 5 is connected to the cylinder cover 32, and the end of the conveying pipe 5 connected to the cylinder cover 32 is sleeved with a filter cover 51, and the other end of the conveying pipe 5 is connected to the pipe wall on one side of the docking pipe 1, so that the filtered gas can be transported through the conveying pipe 5 and can be transported to the docking pipe 1 again after metering and detection, so that the gas can enter the exhaust pipe of the ferroalloy smelting equipment again for discharge.

[0045] Furthermore, the pipe body of the delivery pipeline 5 passes through the metering housing 4 , and the metering housing 4 includes a shell 41 , and the metering instrument body 6 is fixedly clamped in the shell 41 to fix the installation position of the metering instrument body 6 .

[0046] Furthermore, a connecting seat 42 is connected to the upper end of the shell 41, and the connecting seat 42 is connected to the tube wall of the docking tube 1. A glass observation window 43 is provided on the shell body of the shell 41, and the connecting seat 42 can be used to combine the metering shell 4 and the docking tube 1, thereby ensuring that the metering instrument body 6 fixedly placed in the metering shell 4 remains stable, and the arranged glass observation window 43 also facilitates the observation of the metering detection data of the metering instrument body 6.

[0047] Working principle: a part of the exhaust gas flowing from the butt-joint pipe 1 will enter the L-shaped connecting pipe 2, and the exhaust gas will be first introduced into the filtrate through the air inlet pipe 38, so that dust and other impurities can be separated from the gas components in the exhaust gas, thereby filtering the exhaust gas. While filtering the exhaust gas, the gas components in the exhaust gas can also be cooled, and cold water is transported to the spiral cold water pipe 35 through the inlet and outlet water joints to cool the polar solvent, that is, the transferred heat in the exhaust gas can be taken away, and the filtered gas is transported through the transport pipe 5, and can be transported to the butt-joint pipe 1 again after metering and detection, so that the gas can enter the exhaust pipe of the ferroalloy smelting equipment again for discharge.
