Referring to fig. 1, the present embodiment provides a pipeline with a slag accumulation preventing function, which includes a gas pipe 100, a cyclone separation device 200 is disposed on the gas pipe 100, a Y-type filter 300 is connected to a gas outlet 230 of the cyclone separation device 200, a vertical pipe 400 is connected to a slag outlet at the bottom of the cyclone separation device 200, and a magnetic sealing assembly 410 is disposed at the bottom of the vertical pipe 400.
The cyclone separation device 200 is arranged on the pipeline with the slag accumulation preventing function in the embodiment, the gas in the gas pipe 100 is primarily separated, the particle impurities in the gas are removed, then the gas is filtered again through the Y-shaped filter 300, the particles in the gas are further removed, the probability of blocking a subsequent valve by solid particle impurities is reduced, meanwhile, the abrasion of the solid particle impurities on the subsequent valve is reduced, and the service life of the valve is prolonged.
In this embodiment, a standpipe 400 is disposed on the bottom slag hole of the cyclone separator 200, so that the separated solid particulate impurities are discharged into the standpipe 400, and are accumulated in the standpipe 400, and after the materials in the standpipe 400 accumulate to a certain extent, the magnetic sealing component 410 at the bottom is opened, so that the accumulated particulate impurities are discharged. In this embodiment, the separated impurities contain a large amount of rust, the main component is ferroferric oxide, and the magnetic sealing component 410 is provided to provide attraction force for the magnetic particle impurities, and the magnetic particle impurities are relatively uniformly distributed in the particle impurities, so that floating of the particle impurities and the movement of the settled magnetic particle impurities along with the airflow to the subsequent pipelines can be inhibited to a certain extent. It should be noted that, the structure of the magnetic sealing assembly 410 in this embodiment is not particularly required, and a conventional sealing structure, such as a sealing cover, may be used, the sealing cover may be in threaded connection with the standpipe 400, the sealing cover may be made of magnetic material, or a magnetic block may be fixed inside the sealing cover; the length of standpipe 400 can generally need to be set to 20-100cm.
In general, for the case that the particle size of some impurity particles is large, the existing cyclone separation device 200 can be directly adopted, but the gas pipe 100 in this embodiment can be used for conveying coke oven gas, blast furnace gas or a mixed gas of the coke oven gas and blast furnace gas, the water content and the impurity content of these gases are relatively large, and the particle size of the particle impurities therein is small, only tens of micrometers or even several micrometers, so that the standpipe 400 needs to be arranged to cooperate with the magnetic seal assembly 410 to perform gas-solid separation.
The pipeline with the slag accumulation preventing function can be effectively separated, the service life of the follow-up accurate control valve can be prolonged, and the fault phenomena of dead closing, air leakage and slow valve core blocking response are effectively reduced.
In an alternative embodiment, a first valve 500 is disposed on a side of the cyclone separating apparatus 200 away from the Y-shaped filter 300, a second valve 600 is disposed on a side of the Y-shaped filter 300 away from the cyclone separating apparatus 200, and a second purge port 800 is disposed between the second valve 600 and the Y-shaped filter 300.
In this embodiment, the second purge port 800 is disposed on the side of the Y-filter 300 away from the cyclone separator 200, and in cooperation with the arrangement of the first valve 500 and the second valve 600, a purge air source may be connected to the second purge port 800, and the magnetic seal assembly 410 is opened to clean the pipeline, so that the particulate impurities accumulated in the pipeline are discharged from the bottom of the standpipe 400, which is favorable for deep cleaning the pipeline.
In an alternative embodiment, a first purge port 700 is provided between the cyclone separation device and the first valve 500, and when the pipeline is cleaned, the first valve 500 and the second valve 600 may be closed, and simultaneously the first purge port 700, the second purge port 800 and the magnetic sealing assembly 410 at the bottom of the standpipe 400 are opened, so that the pipeline between the first valve 500 and the cyclone separation device may be cleaned.
In an alternative embodiment, the first valve 500 is a pneumatic ball valve; and/or, the second valve 600 is a pneumatic angle seat valve.
The pneumatic angle seat valve has high precision and sensitivity, so that the first valve 500 and the second valve 600 are preferably selected from the pneumatic angle seat valves in general. However, in the application scenario of the embodiment, because the content of impurity particles in the gas at the position of the first valve 500 is high, the phenomena of dead gas leakage prevention and slow valve core blocking response are easy to occur when the pneumatic angle seat valve is adopted, so that the first valve 500 selects the pneumatic ball valve.
In an alternative embodiment, the cyclone separation device comprises a shell and a central cylinder 210 positioned in the shell, an air inlet 220 of the cyclone separation device is positioned on the side wall of the shell and tangential to the shell, an air outlet 230 of the cyclone separation device is positioned at the top of the central cylinder 210, a slag outlet of the cyclone separation device is positioned below the central cylinder 210, and a vertical pipe 400 is positioned below the central cylinder 210 and is coaxially arranged with the central cylinder 210.
When the general cyclone separation device works, high-density particle components in the gas spirally descend along the inner wall of the shell and leave from the slag outlet; the lighter gas component enters the central cartridge 210 from the bottom of the central cartridge 210 and then gradually rises and exits from the gas outlet 230. The vertical tube 400 and the central tube 210 are coaxially arranged, so that the high-density particle components can continuously spirally descend along the inner wall of the vertical tube 400, the insufficient contact state of the gas and the solid phase is maintained, the floating of the particle impurities is reduced, and the falling particle impurities are restrained from moving along with the airflow to the subsequent pipelines again.
In an alternative embodiment, as shown in fig. 2, a funnel-shaped baffle ring 420 is disposed coaxially with the standpipe 400 in the standpipe 400, so as to prevent the settled particulate impurities from moving again along with the airflow into the subsequent pipeline.
In an alternative embodiment, a gap for the passage of particulate material is provided between the top of the funnel-shaped baffle ring 420 and the inner wall of the standpipe 400.
The gas at the slag discharging port of the cyclone separation device has a certain speed, and can continuously spirally descend along the inner wall of the vertical pipe 400, so that solid particles in the gas still have higher content at a position close to the inner wall of the vertical pipe 400, a gap is formed between the top of the funnel-shaped baffle ring 420 and the inner wall of the vertical pipe 400, the gas with higher content of the solid particles is favorable for continuously downwards moving, the gas with lower content of the solid particles in the middle part can upwards move under the action of the suction force of the central cylinder 210 or the extrusion force of the gas below, the floating of the particle impurities is further reduced, the falling particle impurities are restrained from moving along with the gas flow to the subsequent pipelines again, and the separation effect is maintained.
In addition, the baffle ring is funnel-shaped, so that after the gas with higher solid particle content passes through the gap, the expansion speed is reduced, the impact of the gas on the deposited solid particle impurities below is avoided, and the secondary floating of the deposited solid particle impurities is avoided.
In an alternative embodiment, a separation cylinder 430 is connected to the upper end of the funnel-shaped baffle ring 420, and a particulate material channel is provided between the separation cylinder 430 and the inner wall of the standpipe 400.
The presence of the separation barrel 430 facilitates separation of the gas having a higher solids content from the gas having a lower solids content in the middle while maintaining the gas stable and reducing turbulence between the two streams. It should be noted that, the separation barrel 430 and the baffle ring in this embodiment may be connected to the inner wall of the standpipe 400 through a connecting rod, a connecting block, or the like, or may be detachably connected to the magnetic seal assembly 410, and removed together with the magnetic seal assembly 410, so as to facilitate cleaning. Preferably, the top end of the divider 430 is located at the inlet of the standpipe 400, and in some embodiments the divider 430 may be located slightly downward, but not too far from the inlet of the standpipe 400.
In an alternative embodiment, the standpipe 400 and/or the separation cylinder 430 are provided with deceleration ribs, and the deceleration ribs are arranged along the axial direction of the standpipe 400, so as to avoid impact of gas on solid particle impurities deposited below and avoid secondary floating of the deposited solid particle impurities.
In this embodiment, a pneumatic ball valve or a manual ball valve is additionally installed at an air inlet portion of a pipeline to control the on/off of an air source of the branch pipeline, then a first purge port 700 with sealing on/off functions is configured on the pipeline, then the pipeline is connected with a cyclone separation device 200, a sealing plug with a powerful magnet is designed at the bottom of a slag collecting vertical pipe 400 of the cyclone separation device 200, and thus impurities such as rust conveyed along with air are firmly sucked by the powerful magnet when separated by the cyclone separation device 200 and fall into the slag collecting vertical pipe 400 of the cyclone separation device 200, which is beneficial to avoiding secondary floating entering a subsequent conveying pipeline. The gas purified by the cyclone separation device 200 is continuously conveyed backwards, the Y-shaped filter 300 is additionally arranged on the output pipeline of the cyclone separation device 200 for fine filtration, the second purging port 800 with sealing opening and closing functions is further arranged on the output pipeline of the Y-shaped filter 300, then the pipeline is connected with the pneumatic angle seat valve for accurately controlling the output of conveying gas, and the fine filtration of the Y-shaped filter 300 can better ensure the functional precision of the pneumatic angle seat valve and prolong the service life.
When the slag accumulation of the cyclone separation device 200 needs to be cleaned, the slag accumulation in the vertical pipe 400 can be cleaned by removing the sealing plug with the powerful magnet, if the cleaning with higher requirements is needed, the first purging port 700 and the second purging port 800 can be opened after removing the sealing plug with the powerful magnet, and meanwhile, compressed air or nitrogen can be input to purge and clean even the cleaning liquid meeting the requirements, and the pipeline can be prevented from being damaged.
Another embodiment of the present invention provides a fuel supply apparatus, including a pipeline with a slag accumulation preventing function according to any one of the foregoing embodiments.
When the embodiment is applied to a fuel supply device of kiln equipment, rust and impurities in a burner gas supply branch pipeline can be cleaned, even cleaned, on the condition that a pipeline is not disassembled; the service life of the end accurate control valve can be directly prolonged, the fault phenomena (such as quick-cut valves like pneumatic angle seat valves) that the valve is not dead and air-tight and the valve core is slow in blocking response are reduced, and the practical application effect is good.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present invention should be included in the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
