Description

Technical Field

[0001] The utility model relates to the technical field of graphite synthesis furnace pipelines, in particular to a device for reducing corrosion of a steam system of a graphite synthesis furnace producing by-product steam. Background Art

[0002] The steam piping system of the steam-graphite synthesis furnace is a key component to ensure the efficient operation of the entire process. The main structure of the piping system is composed of high-temperature and pressure-resistant carbon steel or alloy steel pipes to ensure stable operation and safety in high-temperature and high-pressure environments. The diameter and wall thickness of the pipes are designed according to the process flow and operating pressure to minimize energy loss and steam pressure fluctuations while ensuring fluid dynamics stability. At the same time, the selection of connectors and valves in the piping system is crucial. They not only need to be able to withstand high-temperature and high-pressure conditions, but also must ensure reliability and safety under various operating conditions. However, after long-term operation, the inner wall of the steam-graphite synthesis furnace at this stage is prone to deposits such as solid scale. During the process of introducing steam under high temperature and high pressure, the pipe material may corrode or leave residues in the fluid. At this time, the airflow carries these solid impurities in the pipe and enters the graphite synthesis furnace with the steam, thereby generating some by-products in the graphite synthesis furnace. Even if the impurities are very small, they may affect the activity of the catalyst during the synthesis process, resulting in product instability or poor quality. Summary of the Invention

[0003] The purpose of the present utility model is to provide a device for reducing the corrosion of the steam system of a by-product steam graphite synthesis furnace. A Y-shaped three-way inlet pipe, an air guide pipe and a Y-shaped three-way discharge pipe are sequentially added at the air inlet of the steam pipe of the steam graphite synthesis furnace, and a front drainage main pipe and a forked sedimentation pipe for diverting gas and solid impurities are added to the inlet of the Y-shaped three-way discharge pipe. When the solid impurities in the air flow pass through the front drainage main pipe, they enter the forked sedimentation pipe under the action of gravity and external suction, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for reducing the corrosion of the steam system of a by-product steam graphite synthesis furnace, comprising an E-shaped bracket and an air duct welded and installed on both sides of the bottom end of the E-shaped bracket, the two same ends of the two air ducts are respectively installed with a Y-shaped three-way discharge pipe and a Y-shaped three-way inlet pipe, a front drainage main pipe is fixed on the end of the Y-shaped three-way inlet pipe away from the air duct, and a forked sedimentation pipe extending obliquely downward is installed at the bottom end of the front drainage main pipe, the front drainage main pipe and the forked sedimentation pipe are connected to each other, and the first and second retaining rings with circular holes are respectively integrally formed at the two ends inside the front drainage main pipe, and a discharge area is provided inside the front drainage main pipe between the first retaining ring and the second retaining ring.

[0005] Preferably, straight grooves are provided on both sides of the top end of the E-shaped bracket.

[0006] Preferably, an internal threaded cap is threadedly installed on the bottom end of the bifurcated sedimentation pipe, and the bifurcated sedimentation pipe, the internal threaded cap and the front drainage main pipe are all made of alloy steel.

[0007] Preferably, the bottom end of the front drainage main pipe is provided with a through hole which is in communication with the bifurcated sedimentation pipe.

[0008] Preferably, a front material blocking area is provided inside the front drainage main pipe on one side of the first baffle ring, and a guide area is provided inside the Y-shaped three-way inlet pipe on one side of the second baffle ring.

[0009] Preferably, the inner diameter of the second retaining ring is smaller than or equal to the inner diameter of the first retaining ring.

[0010] Compared with the prior art, the beneficial effect of the utility model is that the device for reducing the corrosion of the steam system of the by-product steam graphite synthesis furnace is provided with a front drainage main pipe and a Y-shaped three-way drainage pipe and other structures that cooperate with each other. The first baffle ring and the second baffle ring perform secondary blocking of solid impurities in the airflow. Under the action of gravity, the solid impurities can enter the forked sedimentation tube and continue to accumulate, thereby reducing the possibility of solid impurities being suspended and entering the furnace, avoiding entering the furnace to affect the synthesis reaction, thereby significantly reducing the interference of solid impurities on the graphite synthesis reaction and improving the purity and quality stability of the synthetic product.

[0017] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-5 The present invention provides an embodiment of a device for reducing corrosion of a steam system of a graphite synthesis furnace producing by-product steam, comprising an E-shaped bracket 1 and air guide pipes 2 welded and mounted on both sides of the bottom end of the E-shaped bracket 1, and straight grooves are provided on both sides of the top end of the E-shaped bracket 1;

[0019] A Y-shaped three-way drainage pipe 3 and a Y-shaped three-way inlet pipe 4 are respectively installed at the two same ends of the two air guide pipes 2. A front drainage main pipe 5 is fixed to the end of the Y-shaped three-way inlet pipe 4 away from the air guide pipe 2, and a bifurcated sedimentation pipe 6 extending obliquely downward is installed at the bottom end of the front drainage main pipe 5. The Y-shaped three-way drainage pipe 3 and the Y-shaped three-way inlet pipe 4 form two airflow channels to increase the influx of airflow;

[0020] The front drainage main pipe 5 and the bifurcated settling pipe 6 are connected to each other. A first retaining ring 8 and a second retaining ring 9 with circular holes are integrally formed at both ends of the front drainage main pipe 5. A discharge area 10 is provided inside the front drainage main pipe 5 between the first retaining ring 8 and the second retaining ring 9.

[0021] The function of the front drainage main pipe 5 is to guide the main steam into the furnace, ensuring that the steam enters the furnace body at an appropriate speed and direction, avoiding turbulence and instability during the steam flow process. The Y-shaped structure of the front drainage main pipe 5 and the bifurcated settling pipe 6 allows the mainstream steam to enter smoothly and gives solid impurities the opportunity to be separated and removed in the discharge pipe;

[0022] The staff can unscrew the internal thread cap 7 at the bottom end of the bifurcated settling tube 6, so that the solid impurities accumulated in the bifurcated settling tube 6 can be actively discharged, so as to achieve the purpose of actively maintaining the bifurcated settling tube 6;

[0023] After the internal threaded cap 7 is unscrewed, the staff can also connect the bifurcated settling pipe 6 to the external pumping device, so that the bottom end of the front drainage main pipe 5 forms a suction force with the bifurcated settling pipe 6 as the direction, and a part of the air flow and solid impurities in the front drainage main pipe 5 are diverted out under the action of the suction force. At this time, the steam after preliminary filtration can continue to pass through the front drainage main pipe 5, the Y-shaped three-way inlet pipe 4, the air guide pipe 2, and the Y-shaped three-way discharge pipe 3 into the steam-graphite synthesis furnace to ensure the cleanliness of the gas supply to the steam-graphite synthesis furnace. However, this method will lose a part of the steam volume, and steam compensation will need to be performed on the steam-graphite synthesis furnace later.

[0024] The bottom end of the front drainage main pipe 5 is provided with a through hole 501 that is in communication with the bifurcated settling pipe 6. The design of the bifurcated settling pipe 6 utilizes gravity and possible external suction to allow solid particles to sink and settle in the pipe.

[0025] The bottom end of the bifurcated settling pipe 6 is threadedly mounted with an internal threaded cap 7. The bifurcated settling pipe 6, the internal threaded cap 7, and the front drainage main pipe 5 are all made of alloy steel.

[0026] A front material block area 801 is provided inside the front drainage main pipe 5 on the side of the first baffle ring 8, and a guide area 901 is provided inside the Y-shaped three-way inlet pipe 4 on the side of the second baffle ring 9. The inner diameter of the second baffle ring 9 is less than or equal to the inner diameter of the first baffle ring 8. The alloy steel has high high temperature and high pressure resistance and can maintain structural stability and integrity in the high temperature and high pressure environment of the steam graphite synthesis furnace.

[0027] When the embodiment of the present application is in use, the staff first installs the discharge outlet of the Y-shaped three-way drainage pipe 3 to the steam pipe air inlet of the steam graphite synthesis furnace, and connects the front drainage main pipe 5 to the supply end of the external steam airflow, and the steam airflow will enter the steam graphite synthesis furnace through the front drainage main pipe 5, the Y-shaped three-way inlet pipe 4, the air guide pipe 2, and the Y-shaped three-way drainage pipe 3 in sequence. In this process, the first baffle ring 8 and the second baffle ring 9 form two blocking layers inside the front drainage main pipe 5, and the through holes inside the first baffle ring 8 and the second baffle ring 9 are for the airflow to pass through. The solid impurities carried by the airflow have a certain gravity, so their travel path is relatively low, and thus are trapped by the first baffle ring 8 and the second baffle ring 9. The retaining ring 8 and the second retaining ring 9 block the solid impurities in the air flow, thereby preventing the solid impurities in the air flow from entering the subsequent Y-shaped three-way inlet pipe 4, the air guide pipe 2 and other pipes, so as to reduce the amount of solid impurities entering. If the first retaining ring 8 does not block the solid impurities, the solid impurities will enter the discharge area 10 between the first retaining ring 8 and the second retaining ring 9, and will be blocked for the second time by the second retaining ring 9. The solid impurities can enter the forked sedimentation tube 6 under the action of gravity and continue to accumulate, thereby reducing the possibility of solid impurities being suspended and entering the furnace, avoiding entering the furnace to affect the synthesis reaction, thereby significantly reducing the interference of solid impurities on the graphite synthesis reaction and improving the purity and quality stability of the synthetic product.
