Description

Technical Field

[0001] This utility model relates to the field of water chamber partition technology, and in particular to a novel high-pressure heater water chamber partition device. Background Technology

[0002] The baffle plate of the water chamber of the high-pressure heater mainly serves to guide and distribute the water flow. It allows the water to flow along a specific path, so that the water flows evenly through the heating tube bundle, fully carrying out heat exchange. It can also reasonably distribute the flow rate and avoid water flow short circuits, thereby improving heating efficiency.

[0003] In existing high-pressure heater water chambers, the baffles are designed in a stacked manner. During operation, due to the continuous action of high temperature and high pressure, the connecting parts of the baffles deform. This deformation damages the sealing surface of the stacked parts, leading to leakage. Once leakage occurs, it creates new short-circuit channels, allowing water to flow directly through these channels, bypassing the heating tube bundle, ultimately resulting in reduced heating efficiency. In view of this, this application proposes a novel baffle device for high-pressure heater water chambers based on the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel high-pressure heater water chamber baffle device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel high-pressure heater water chamber baffle device includes a baffle body, a sealing surface on one side of the baffle body, a sealing component on the sealing surface, and a protective layer, a nickel wire layer, and a graphite layer arranged from the outside to the inside. The baffle body has a plurality of grooves, and bolts are installed in the grooves. The sealing component is fixedly installed on the baffle body by bolts.

[0007] Furthermore, the partition body is provided with flow guide grooves on both sides, with one side of the flow guide groove being the water inlet and the other side being the water outlet.

[0008] Furthermore, the guide channel is wavy, and the depth of the guide channel gradually decreases from the inlet end to the outlet end.

[0009] Furthermore, the partition body is made of austenitic stainless steel, and the surface of the partition body is coated with anti-oxidation ceramic.

[0010] Furthermore, the nickel wire layer is made up of several nickel wires woven alternately.

[0011] Furthermore, the peak height of the guide groove is 5-8mm, and the trough depth is 2-3mm.

[0012] Furthermore, the nickel wire layer is embedded with thermally expanding particles, which are alumina-silicon carbide composite ceramic materials.

[0013] Furthermore, the material of the protective layer is polytetrafluoroethylene.

[0014] Furthermore, the inner wall of the flow channel is coated with a hydrophobic layer, and the material of the hydrophobic layer is silicon dioxide.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting a sealing component and applying pre-tightening force to the bolts, ensures that the sealing component is tightly fixed to the partition body, preventing displacement. The partition body, as the core structural component, supports the sealing component and withstands the impact of high-pressure water flow. The protective layer blocks external corrosion, the nickel wire layer disperses pressure and inhibits deformation, and the graphite layer fills the sealing gap, reducing the risk of leakage of the partition body. Thus, it ensures the stability and reliability of the high-pressure heater water chamber partition device during long-term operation.

[0017] 2. This utility model, by setting a guide channel, forces the water to flow along a set path at the inlet and outlet ends of the guide channel, avoiding short circuits. The higher wave crests reduce the effective cross-sectional area of ​​the flow channel, forcing the water to accelerate through the wave crest area, enhancing turbulent mixing with the heating tube bundle, and improving heat exchange efficiency. The lower wave troughs form a smooth transition zone, reducing flow resistance. At the same time, the local low pressure promotes the water flow to concentrate towards the wave crests, forming a stable spiral flow path. The high flow velocity zone at the wave crests washes away impurities, while the low flow velocity zone at the wave troughs inhibits scale adhesion through the action of the hydrophobic layer.

[0018] 3. This utility model incorporates thermal expansion particles, which push the nickel wire layer outward at high temperatures, automatically compensating for the gap in the sealing surface and addressing irreversible deformation caused by long-term high temperatures. The partition body, made of austenitic stainless steel with high-temperature resistance, further reduces the risk of deformation, and its surface anti-oxidation ceramic helps prevent corrosion by chloride ions while also being resistant to erosion.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-3 A novel high-pressure heater water chamber baffle device includes a baffle body 1, a sealing surface 2 on one side of the baffle body 1, a sealing component on the sealing surface 2, and a protective layer 3, a nickel wire layer 4, and a graphite layer 5 arranged from the outside to the inside. A plurality of grooves 6 are provided on the baffle body 1, and bolts are provided in the grooves 6. The sealing component is fixedly installed on the baffle body 1 by bolts.

[0026] Pre-tightening force is applied to the bolts to ensure that the sealing assembly is tightly fixed to the baffle body 1, preventing displacement. The baffle body 1, as the core structural component, supports the sealing assembly and withstands the impact of high-pressure water flow. The protective layer 3 blocks external corrosion, the nickel wire layer 4 disperses pressure and inhibits deformation, and the graphite layer 5 fills the sealing gap, reducing the risk of leakage of the baffle body 1. This ensures the stability and reliability of the high-pressure heater water chamber baffle device during long-term operation.

[0027] Reference Figure 4 Specifically: the partition body 1 is provided with flow guide grooves 7 on both sides. One side of the flow guide groove 7 is set as the water inlet 8 and the other side is set as the water outlet 9. The water inlet 8 and the water outlet 9 of the flow guide groove 7 force the water to flow along the set path to avoid short circuit.

[0028] Reference Figure 4 Specifically: the guide channel 7 is wave-shaped, and the depth of the guide channel 7 gradually decreases from the inlet end 8 to the outlet end 9. The deeper guide channel 7 can reduce the impact force of high-speed water flow and reduce local turbulence, while the shallower guide channel 7 can moderately increase the water flow speed and prevent heat accumulation or flow stagnation at the outlet end 9 due to excessively low flow velocity.

[0029] Reference Figure 1 Specifically: the material of the partition body 1 is austenitic stainless steel, and the surface of the partition body 1 is coated with anti-oxidation ceramic. The partition body 1 made of austenitic stainless steel with high temperature resistance further reduces the risk of deformation, and the anti-oxidation ceramic on its surface helps to avoid corrosion by chloride ions, while also being resistant to erosion.

[0030] Reference Figure 3 Specifically: the nickel wire layer 4 is made of several nickel wires woven alternately, and the alternatingly woven nickel wire layer 4 forms an elastic buffer space to prevent the sealing surface 2 from lifting.

[0031] Reference Figure 4 Specifically: the height of the wave crest of the guide channel 7 is 5-8mm, and the depth of the wave trough is 2-3mm. The higher wave crest reduces the effective cross-sectional area of ​​the flow channel, forcing the water to accelerate through the wave crest area, enhancing the turbulent mixing with the heating tube bundle, and improving the heat exchange efficiency. The lower wave trough forms a smooth transition zone, reducing flow resistance. At the same time, the local low pressure promotes the water flow to concentrate towards the wave crest, forming a stable spiral flow path. The high flow velocity zone at the wave crest washes away impurities.

[0032] Reference Figure 3 Specifically: The nickel wire layer 4 is embedded with thermal expansion particles, which are made of alumina-silicon carbide composite ceramic material. At high temperatures, the thermal expansion particles push the nickel wire layer 4 to expand outward, automatically compensating for the gap in the sealing surface 2 and coping with irreversible deformation caused by long-term high temperature.

[0033] Reference Figure 3 Specifically, the material of the protective layer 3 is polytetrafluoroethylene.

[0034] Reference Figure 4 Specifically: the inner wall of the flow channel 7 is coated with a hydrophobic layer 10, the material of the hydrophobic layer 10 is silicon dioxide, and the low flow velocity area of ​​the trough is inhibited by the action of the hydrophobic layer 10 to suppress the adhesion of scale.

[0035] Working principle: Applying pre-tightening force to the bolts ensures that the sealing assembly is tightly fixed on the diaphragm body 1 to prevent displacement. The diaphragm body 1, as the core structural component, supports the sealing assembly and withstands the impact of high-pressure water flow. The protective layer 3 blocks external corrosion, the nickel wire layer 4 disperses pressure and inhibits deformation, and the graphite layer 5 fills the sealing gap, reducing the risk of leakage of the diaphragm body 1, thereby ensuring the stability and reliability of the high-pressure heater water chamber diaphragm device during long-term operation.

[0036] The inlet end 8 and outlet end 9 of the guide channel 7 force the water to flow along a set path to avoid short circuits. The higher wave crests reduce the effective cross-sectional area of ​​the flow channel, forcing the water to accelerate through the wave crest area, enhancing the turbulent mixing with the heating tube bundle and improving heat exchange efficiency. The lower wave troughs form a smooth transition zone, reducing flow resistance. At the same time, the local low pressure promotes the water flow to concentrate towards the wave crests, forming a stable spiral flow path. The high flow velocity zone at the wave crests flushes away impurities, while the low flow velocity zone at the wave troughs inhibits scale adhesion through the hydrophobic layer 10.

[0037] At high temperatures, thermal expansion particles push the nickel wire layer 4 outward to automatically compensate for the gap in the sealing surface 2, and cope with irreversible deformation caused by long-term high temperature. The partition body 1, made of austenitic stainless steel with high temperature resistance, further reduces the risk of deformation. Its surface anti-oxidation ceramic helps to avoid corrosion by chloride ions and is also resistant to erosion.

[0038] The alternating woven nickel wire layer 4 forms an elastic buffer space to prevent the sealing surface 2 from lifting.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
