A glass steel pipe for a ship desulfurization system with high temperature and corrosion resistance

Abstract

The present application discloses a fiberglass pipe for a ship desulfurization system with high temperature and corrosion resistance, which is applied to the field of desulfurization fiberglass pipes. Through the design with a gasket, an anti-corrosion lining layer and an actuator ring, when leakage occurs at the bonded end, hydrogen sulfide will enter the ventilation cavity through the waterproof breathable membrane and enter the reaction cavity through the ventilation holes in the ventilation cavity. At this time, the leaked hydrogen sulfide will undergo an acid-base neutralization reaction with the reaction filler, and the water-absorbing and swelling filler will adsorb the water generated by the reaction and generate its own expansion. The expansion pressure is transmitted to the actuator ring, which in turn drives the lever to flip, causing the actuator head to turn outwards and squeeze the sealing ring, thereby improving the sealing performance between the sealing ring and the active sealing groove. The sealing ring will also squeeze the extrusion groove, thereby being able to pressurize the leaked bonded end, effectively preventing the continuous leakage of hydrogen sulfide and avoiding its corrosion of the fiberglass pipe in the ship desulfurization system after leakage, and effectively improving the corrosion resistance of the fiberglass pipe.

Description

Technical Field

[0001] This application relates to the field of desulfurization fiberglass pipes, and particularly to a fiberglass pipe for a ship desulfurization system with high temperature and corrosion resistance. Background Art

[0002] With the continuous improvement of human awareness of environmental protection, the international emissions of ship gases have become increasingly strict, and new emission standards have been introduced continuously. The IMO has issued a series of resolutions on emission restrictions, including restrictions on sulfur compound emissions. In order to respond to the restrictions on sulfur compound emissions and comprehensively consider factors such as upfront investment, operating costs, maintenance costs, and return on investment, most shipowners currently choose to install desulfurization scrubbers to meet the regulatory requirements.

[0003] For the existing fiberglass pipes used in ship desulfurization systems, their connection nodes do not meet the requirements of bumpy navigation, and it is easy to cause hydrogen sulfide leakage in the desulfurization system. Since most fiberglass pipes only have anti-sulfur design on the inner wall, the outer wall has poor protection. During long-term operation, after node leakage occurs, it is easy to damage the outer wall of the fiberglass pipe, resulting in a decrease in its high temperature and corrosion resistance, and there are certain safety hazards.

[0004] The applicant conceives a fiberglass pipe whose connection can effectively prevent the leakage of hydrogen sulfide in the ship desulfurization system, so as to prevent the leaked hydrogen sulfide from corroding the outer wall of the fiberglass pipe with weak protection. For this reason, we propose a fiberglass pipe for a ship desulfurization system with high temperature and corrosion resistance to solve the above problems. Summary of the Invention

[0005] The purpose of this application is to design a fiberglass pipe whose connection can effectively prevent the leakage of hydrogen sulfide in the ship desulfurization system, so as to prevent the leaked hydrogen sulfide from corroding the outer wall of the fiberglass pipe with weak protection. Compared with the prior art, a fiberglass pipe for a ship desulfurization system with high temperature and corrosion resistance is provided. Through the setting of the fiberglass pipe, the end of the fiberglass pipe is hermetically connected through a connecting flange, a sealing gasket is clamped between two opposite connecting flanges, an inner lining layer is adhesively bonded to the inner wall of the fiberglass pipe, the inner lining layer is provided with an adhesive end at the connecting flange, and an extrusion groove corresponding to the adhesive end is arranged on the inner side of the circular ring of the sealing gasket;

[0006] A reaction cavity is arranged in the sealing gasket, a breathable cavity is fixed in the reaction cavity, a waterproof breathable membrane is fixed between the breathable cavity and the extrusion groove, a plurality of breathable holes are arranged on the breathable cavity, and reaction fillers and water-absorbing expansion fillers are arranged on both sides of the breathable cavity in the reaction cavity;

[0007] Actuating rings are symmetrically arranged on both sides of the sealing gasket, and a number of push rods are evenly arranged on the actuating rings at equal angles. The sealing gasket is provided with sliding holes matching the push rods. A sealing ring is provided on one side of the connecting flange, and a through hole matching the push rod is provided on the sealing ring. One end of the push rod passes through the through hole and extends to one side of the connecting flange. A tensioning spring is clamped between the push rod and the connecting flange. The end of the push rod is rotatably connected to a force rod. Two force rods are symmetrically arranged at the end of the push rod. The other end of the force rod is rotatably connected to the connecting flange, and an actuating end is fixed to the end of the force rod.

[0008] The sealing ring is an N-shaped circular ring structure in cross section, and the side of the sealing gasket is provided with active sealing grooves corresponding to the two N-shaped ends of the sealing ring.

[0009] When the glue at the glue joint ageing and leakage gap occurs, the hydrogen sulfide in the ship desulfurization system will enter the breathable cavity through the waterproof breathable membrane and enter the reaction cavity through the breathable hole of the breathable cavity. At this time, the leaked hydrogen sulfide and the reaction filler produce an acid-base neutralization reaction, and the reaction formula of the two is: H2S+Ca(OH)2=CaS+2H2O, wherein the water-absorbing and swelling filler absorbs the water produced by the reaction and produces its own expansion, and its expansion pressure is transmitted to the execution ring, so that the execution ring pushes the push rod to overcome the tensioning spring to displace, thereby driving the power rod to flip, so that the execution end head turns outward and squeezes the sealing ring, thereby achieving the improvement of the sealing between the sealing ring and the active sealing groove, and the sealing ring will squeeze the extrusion groove at the same time, thereby pressurizing the leaking glue joint end, which can effectively prevent the continuous leakage of hydrogen sulfide, avoid the corrosion of the glass fiber reinforced plastic pipe in the ship desulfurization system after the leakage, and effectively improve the corrosion resistance of the glass fiber reinforced plastic pipe. The invention has market prospects and is suitable for popularization and application.

[0010] Furthermore, the anti-corrosion lining layer is made of cold-lined butyl rubber material, and the sealing gasket is made of EPDM rubber material.

[0011] Furthermore, an elastic observation piece is provided on the outer side of the circumference of the sealing gasket. The elastic observation piece is made of transparent rubber material. The elastic observation piece has elastic force to bend toward the outer side of the circumference of the sealing gasket in a free state.

[0012] Furthermore, two passive sealing ends are provided on the outer side of the circumference of the sealing gasket, and the two passive sealing ends are symmetrically arranged on both sides of the elastic observation piece.

[0013] Furthermore, the reactive filler is calcium hydroxide powder, the water-absorbing and swelling filler is water-absorbing resin particles, and the water-absorbing and swelling filler is also doped with anhydrous copper sulfate powder.

[0014] Furthermore, the tension spring has an elastic force that drives the push rod and the actuating ring away from the connecting flange. When the tension spring is not under pressure, the actuating end of the force rod flips inward and does not conflict with the sealing ring.

[0015] Furthermore, the force rod is an arc-shaped rod structure, and the length of the force rod is three times the length of the execution end.

[0016] Furthermore, the execution end is an eccentric wheel structure, and a wear-resistant ceramic pad is fixed on the side of the execution end that contacts the sealing ring.

[0017] Furthermore, the adhesive ends are in a circular ring structure, and connecting grooves are provided on opposite sides of the two adhesive ends, and the two adhesive ends are bonded together by phenolic resin glue.

[0018] Furthermore, a plurality of sealing grooves are provided on the side where the passive sealing end contacts the connecting flange and on the side where the active sealing groove contacts the sealing ring, and the two opposite connecting flanges are fixedly connected by bolts.

[0019] Compared with the prior art, the advantages of this application are:

[0020] (1) The present invention cooperates with the sealing gasket with reactive filler, water-swellable filler, active sealing groove, reaction chamber, and extrusion groove, the anti-corrosion lining layer with the glued end, and the execution ring with the push rod, tension spring, force rod, and execution end. In actual use, when the anti-corrosion lining layers in two FRP pipes to be connected are butt-jointed, the butt-jointing method is the gluing operation of the glued end. At this time, the sealing gasket is clamped and placed between the connecting flanges of the FRP pipe, and the glued end is prevented from being in the extrusion groove. At this time, the connecting flanges are connected by bolts. Under the connection pressure of the bolts, the two connecting flanges are close to each other and squeeze the sealing gasket, so that the extrusion groove is compressed to clamp the glued end, thereby achieving the purpose of sealed connection.

[0021] (2) When the glue at the glue joint ages and a leakage gap is generated, the hydrogen sulfide in the ship desulfurization system will enter the breathable cavity through the waterproof breathable membrane and enter the reaction cavity through the breathable hole of the breathable cavity. At this time, the leaked hydrogen sulfide and the reaction filler produce an acid-base neutralization reaction, and the reaction formula of the two is: H2S+Ca(OH)2=CaS+2H2O, wherein the water-absorbing and swelling filler absorbs the water produced by the reaction and produces its own expansion. The expansion pressure is transmitted to the actuator ring, so that the actuator ring pushes the push rod to overcome the tension spring and displace, thereby driving the power rod to flip, so that the actuator end head turns outward and squeezes the sealing ring, thereby improving the sealing between the sealing ring and the active sealing groove. At the same time, the sealing ring squeezes the extrusion groove, thereby pressurizing the leaking glue joint end, which can effectively prevent the continuous leakage of hydrogen sulfide and avoid its leakage to corrode the glass fiber reinforced plastic pipe in the ship desulfurization system. It can effectively improve the corrosion resistance of the glass fiber reinforced plastic pipe, has market prospects, and is suitable for promotion and application.

[0022] (3) Through the material design of the anti-corrosion lining layer and the gasket, both of them have the characteristics of high temperature resistance and resistance to hydrogen sulfide corrosion, so as to improve the high temperature and corrosion resistance of the fiberglass pipe for ship desulfurization systems, thereby extending its service life and reducing the usage cost.

[0023] (4) Through the design of the elastic observation member with a passive sealing end, when leakage occurs at the bonded end and hydrogen sulfide in the desulfurization system enters the reaction chamber, it reacts with the reaction filler and generates water. After the water-swellable filler absorbs water and swells, the anhydrous copper sulfate powder in the water-swellable filler absorbs water and changes color, enabling maintenance personnel to directly detect the leakage point, facilitating maintenance and risk elimination. On the other hand, the continuous occurrence of leakage allows the positive-pressure hydrogen sulfide to enter the reaction chamber, increasing the pressure inside the reaction chamber. The change in pressure causes the elastic observation member to turn outwards, and then the passive sealing ends on both sides of it move away from each other and turn outwards, so that the passive sealing end tightly abuts against the connecting flange, achieving the purpose of secondary leakage prevention. On the other hand, the turned-out elastic observation member can form a convex mirror structure to magnify the color change reaction of the anhydrous copper sulfate powder, facilitating the inspection and observation by maintenance personnel.

[0024] (5) Through the design of the length ratio of the force rod and the execution end, using the lever principle, only a relatively small thrust is required to drive the push rod to make the execution end turn outwards. Then, through the variable diameter operation of the eccentric wheel structure, the sealing ring is pushed away from the connecting flange, so that the two side ends of the sealing ring can further fit with the active sealing groove, achieving the purpose of increasing the sealing performance. At the same time, through the design of the execution end with wear-resistant ceramic pads, the friction force received by the execution end during the outward turning action is reduced, improving the smoothness and wear resistance during the system execution.

[0025] (6) Through the design of the connecting groove, the bonding during the bonding process of the bonded end is made closer. Through the design of the sealing groove, when the connecting flanges are fixedly connected by bolts, the active sealing groove of the gasket and the end of the sealing ring are extruded and fitted, forming an effective double-layer sealing performance, which can effectively prevent hydrogen sulfide in the desulfurization system from leaking and corroding the outer wall of the fiberglass pipe, improving the protection performance.

Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0039] Embodiment 1:

[0040] This application discloses a fiberglass pipe for a ship desulfurization system with high temperature and corrosion resistance. Please refer to Figures 1-10, including a fiberglass pipe 1, the ends of the fiberglass pipe 1 are hermetically connected through connecting flanges 2, a gasket 3 is clamped between two opposite connecting flanges 2, a lining layer 4 is adhesively bonded to the inner wall of the fiberglass pipe 1, the lining layer 4 is provided with an adhesive end 41 at the connecting flange 2, an extrusion groove 39 corresponding to the adhesive end 41 is provided on the inner ring of the gasket 3, a reaction cavity 37 is provided in the gasket 3, a breathable cavity 38 is fixed in the reaction cavity 37, a waterproof breathable membrane 381 is fixed between the breathable cavity 38 and the extrusion groove 39, a plurality of breathable holes are provided on the breathable cavity 38, and reaction fillers 31 and water-absorbing expansion fillers 32 are provided on both sides of the breathable cavity 38 in the reaction cavity 37;

[0041] Execution rings 5 are symmetrically arranged on both sides of the gasket 3, a plurality of push rods 51 are evenly arranged at equal angles on the execution rings 5, slide holes 34 matching the push rods 51 are provided on the gasket 3, a sealing ring 21 is provided on one side of the connecting flange 2, through holes matching the push rods 51 are provided on the sealing ring 21, one end of the push rod 51 passes through the through hole and extends to the side of the connecting flange 2, a tension spring 52 is clamped between the push rod 51 and the connecting flange 2, the end of the push rod 51 is rotatably connected to a force rod 53, the two force rods 53 are symmetrically arranged at the end of the push rod 51, the other end of the force rod 53 is rotatably connected to the connecting flange 2, and an execution end 531 is fixed at the end of the force rod 53; the sealing ring 21 has a circular ring structure with a sectional N shape, and a main sealing groove 35 corresponding to the two N-shaped ends of the sealing ring 21 is provided on the side of the gasket 3.

[0042] Through the mutual cooperation between the gasket 3 with reaction fillers 31, water-absorbing expansion fillers 32, main sealing grooves 35, reaction cavities 37, and extrusion grooves 39, the anti-corrosion lining layer 4 with an adhesive end 41, and the execution rings 5 with push rods 51, tension springs 52, force rods 53, and execution ends 531, in actual use, when the anti-corrosion lining layers 4 in two fiberglass pipes 1 to be connected are butted, the butting method is the adhesive operation of the adhesive end 41. At this time, the gasket 3 is clamped and placed between the connecting flanges 2 of the fiberglass pipe 1, and the completed adhesive end 41 is placed in the extrusion groove 39. Then, the connecting flanges 2 are connected by bolts. Under the connection pressure of the bolts, the two connecting flanges 2 approach each other and squeeze the gasket 3, so that the extrusion groove 39 is pressed to clamp the adhesive end 41, achieving the purpose of sealed connection.

[0043] When the glue ages at the bonding end 41 and leakage gaps are generated, hydrogen sulfide in the ship desulfurization system will enter the ventilation cavity 38 through the waterproof breathable membrane 381, and enter the reaction cavity 37 through the ventilation holes of the ventilation cavity 38. At this time, the leaked hydrogen sulfide reacts with the reaction filler 31 to produce an acid-base neutralization reaction. The reaction formula of the two is: H2S + Ca(OH)2 = CaS + 2H2O. Among them, the water-absorbing and swelling filler 32 will adsorb the water generated by the reaction and cause its own swelling. Its swelling pressure is transmitted to the actuator ring 5, causing the actuator ring 5 to push the push rod 51 to displace against the tension spring 52, and then driving the lever 53 to flip, so that the actuator end 531 turns outwards and squeezes the sealing ring 21, thereby improving the sealing performance between the sealing ring 21 and the active sealing groove 35. The sealing ring 21 will also squeeze the extrusion groove 39, thereby being able to pressurize the leaking bonding end 41, effectively preventing the continuous leakage of hydrogen sulfide, avoiding its corrosion of the fiberglass pipe 1 in the ship desulfurization system after leakage, effectively improving the corrosion resistance of the fiberglass pipe 1, having market prospects, and being suitable for popularization and application.

[0044] It should be noted that in this embodiment, the anti-corrosion lining layer 4 is made of cold-lined butyl rubber material, and the gasket 3 is made of ethylene propylene diene monomer rubber material.

[0045] Through the material design of the anti-corrosion lining layer 4 and the gasket 3, both of them have the characteristics of high temperature resistance and hydrogen sulfide corrosion resistance, so as to improve the high temperature and hydrogen sulfide corrosion resistance of the fiberglass pipe for ship desulfurization systems, thereby extending its service life and reducing the use cost.

[0046] Specifically, please refer to Figures 1-10 , an elastic observation member 36 is provided on the circumferential outer side of the gasket 3. The elastic observation member 36 is made of transparent rubber material. The elastic observation member 36 has an elastic force that bends towards the circumferential outer side of the gasket 3 in a free state. Two passive sealing ends 33 are provided on the circumferential outer side of the gasket 3. The two passive sealing ends 33 are symmetrically arranged on both sides of the elastic observation member 36. The reaction filler 31 is calcium hydroxide powder, and the water-absorbing and swelling filler 32 is water-absorbing resin particles. Anhydrous copper sulfate powder is also doped in the water-absorbing and swelling filler 32.

[0047] Through the design of the elastic viewing member 36 with a passive sealing end 33, when leakage occurs at the bonded end 41 and hydrogen sulfide in the desulfurization system enters the reaction chamber 37, it reacts with the reaction filler 31 and generates water. After the water-swellable filler 32 absorbs water and swells, the anhydrous copper sulfate powder in the water-swellable filler 32 absorbs water and changes color, enabling maintenance personnel to directly detect the leakage point, facilitating maintenance and risk elimination. On the other hand, the continuous occurrence of leakage allows the positive-pressure hydrogen sulfide to enter the reaction chamber 37, increasing the pressure inside the reaction chamber 37. The change in pressure causes the elastic viewing member 36 to turn outwards, and further causes the passive sealing ends 33 on both sides to move away from each other and turn outwards, so that the passive sealing end 33 tightly abuts against the connecting flange 2, achieving the purpose of secondary leakage prevention. On the other hand, the turned-out elastic viewing member 36 can form a convex mirror structure to magnify the color change reaction of the anhydrous copper sulfate powder, facilitating the inspection and observation by maintenance personnel.

[0048] Specifically, please refer to Figures 1-10 , the tension spring 52 has an elastic force that drives the push rod 51 and the actuator ring 5 away from the connecting flange 2. When the tension spring 52 is in an uncompressed state, the actuator end 531 of the lever 53 flips and retracts and does not contact the sealing ring 21. The lever 53 is an arc-shaped rod structure, and the length of the lever is three times the length of the actuator end 531. The actuator end 531 is an eccentric wheel structure, and a wear-resistant ceramic pad is fixed on the side of the actuator end 531 that contacts the sealing ring 21.

[0049] Through the design of the length ratio of the lever 53 and the actuator end 531, using the lever principle, only a small thrust is required to drive the push rod 51 to turn the actuator end 531 outwards. Then, through the variable diameter operation of the eccentric wheel structure, the sealing ring 21 is pushed away from the connecting flange 2, so that the two side ends of the sealing ring 21 can be further fitted with the active sealing groove 35, achieving the purpose of increasing the sealing performance. At the same time, through the design of the actuator end 531 with a wear-resistant ceramic pad, the friction force received by the actuator end 531 during the outward turning action is reduced, improving the smoothness and wear resistance during the system operation.

[0050] Specifically, please refer to Figures 1-10 , the bonded end 41 is in a circular ring structure. Connecting grooves are provided on both sides of the two bonded ends 41 that face each other. The two bonded ends 41 are adhered through phenolic resin glue. Multiple sealing grooves are provided on the side of the passive sealing end 33 that contacts the connecting flange 2 and on the side of the active sealing groove 35 that contacts the sealing ring 21. The two opposite connecting flanges 2 are fixedly connected by bolts.

[0051] Through the design of the connecting groove, the bonding end 41 is more tightly bonded during the bonding process. Through the design of the sealing groove, when the connecting flanges 2 are fixedly connected by bolts, the active sealing groove 35 of the gasket 3 is pressed and fitted with the end of the sealing ring 21 to form an effective double-layer sealing performance, which can effectively prevent the hydrogen sulfide in the desulfurization system from leaking and corroding the outer wall of the fiberglass pipe, thus improving the protection performance.

[0052] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its improved concept of the present application, making equivalent substitutions or changes, should be covered by the protection scope of the present application.
