Description

Technical Field

[0001] This application relates to the field of electric heating technology, and in particular to a high-temperature venting device. Background Technology

[0002] A closed-loop electric heater is a device that converts electrical energy into heat energy in a relatively enclosed heating system. It typically consists of a heating element, a container shell, insulation materials, and control devices.

[0003] In related technologies, high-temperature and high-pressure gas heated by a closed electric heater needs to be discharged. However, the exhaust pipe and exhaust valve cannot withstand high temperature and high pressure at the same time and work stably. To solve this problem, heat insulation material is laid inside the exhaust pipe to reduce the temperature that the exhaust pipe is subjected to, so that it only bears the pressure.

[0004] However, due to structural limitations, exhaust valves cannot be lined with internal insulation materials like exhaust pipes, resulting in a typically shorter lifespan and significant drawbacks. Summary of the Invention

[0005] To address the problem that existing exhaust valves are unsuitable for continuous high-temperature gas emissions, this application provides a high-temperature venting device.

[0006] The high-temperature relief device provided in this application adopts the following technical solution: A high-temperature venting device includes a cooling core cylinder with multiple first cooling holes for gas discharge. One end of the cooling core cylinder is connected to an exhaust valve, and the other end is connected to an exhaust pipe. A hollow flow ring chamber is arranged on the outer wall of the cooling core cylinder. A first partition plate is arranged inside the flow ring chamber to divide its inner cavity into a first inlet chamber and a first outlet chamber. Multiple first liquid inlet channels connected to the first inlet chamber and multiple first liquid outlet channels connected to the first outlet chamber are provided inside the cooling core cylinder. The first liquid inlet channels and the first liquid outlet channels communicate with each other.

[0007] By adopting the above technical solution, high-temperature air flows from the exhaust pipe through the first cooling hole and then is discharged through the exhaust valve. During this process, cooling water enters each of the first liquid inlet channels from the first inlet cavity, then flows into the first outlet cavity from each of the first liquid outlet channels and is finally discharged. At this time, heat exchange between the cooling water and the high-temperature air is achieved, which rapidly reduces the temperature of the high-temperature air, making its temperature meet the requirements for the continuous and effective operation of the exhaust valve and extending the service life of the exhaust valve.

[0008] Optionally, an outlet inner pipe is connected between the exhaust pipe and the cooling core cylinder. The outlet inner pipe extends into the exhaust pipe. A flow-through ring cylinder is provided as an outer cover at the connection between the cooling core cylinder and the outlet inner pipe. A second partition plate is arranged inside the flow-through ring cylinder to divide its inner cavity into a second inlet cavity and a second outlet cavity. The first liquid inlet channel is connected to the second inlet cavity, and the first liquid outlet channel is connected to the second outlet cavity. A flow exchange cavity is formed in the wall thickness of the outlet inner pipe extending into the exhaust pipe. A plurality of second cooling holes are also formed in the wall thickness of the outlet inner pipe, which are respectively connected to the second inlet cavity and the second outlet cavity. The other end of each second cooling hole relative to the flow-through ring cylinder is connected to the flow exchange cavity.

[0009] By adopting the above technical solution, the cooling water in the first inlet channel flows into part of the second cooling hole under the action of the second inlet cavity, flows through the heat exchange chamber, and then flows back to the second outlet cavity from the remaining part of the second cooling hole. This greatly prolongs the heat exchange time between the cooling water and the high-temperature air and improves the cooling effect on the high-temperature air.

[0010] Optionally, the inner outlet pipe and the exhaust pipe are fitted with a clearance and filled with heat insulation cotton, and the inner outlet pipe and the exhaust pipe are connected by a flange.

[0011] Optionally, multiple pull rods are inserted inside the cooling core cylinder, with one pull rod spaced apart in each of the first liquid inlet and first liquid outlet channels. A plug for sealing is slidably sleeved on the end of each pull rod, and a fastening nut for pushing the plug against the end face of the cooling core cylinder is threaded onto the pull rod.

[0012] By adopting the above technical solution, the tie rod, in conjunction with the plug and the fastening nut, seals the extra sections of the first liquid inlet channel and the first liquid outlet channel, reducing the possibility of high-temperature air entering.

[0013] Optionally, the diameters of the tie rods inside the first liquid inlet channel and the first liquid outlet channel gradually increase along the flow direction of the cooling water inside each channel.

[0014] Optionally, the fastening nut is provided with anti-loosening holes, and anti-loosening steel wires are passed through the anti-loosening holes of multiple fastening nuts at the same end of the cooling core cylinder. Anti-loosening steel wires are welded to both ends.

[0015] Optionally, the pull rod is provided with a convex ring for blocking the pushing deformation.

[0016] Optionally, the end of the pull rod is provided with a clamping groove.

[0017] In summary, this application includes at least one of the following beneficial technical effects: High-temperature air flows from the exhaust pipe through the first cooling hole and then is discharged through the exhaust valve. During this process, cooling water enters each of the first liquid inlet channels from the first inlet cavity, then flows into the first outlet cavity from each of the first liquid outlet channels and is finally discharged. This achieves heat exchange between the cooling water and the high-temperature air, rapidly reducing the temperature of the high-temperature air to meet the requirements for the continuous and effective operation of the exhaust valve, thus extending the service life of the exhaust valve. The cooling water in the first inlet channel flows into part of the second cooling hole under the action of the second inlet cavity. After flowing through the heat exchange chamber, it flows back to the second outlet cavity from the remaining part of the second cooling hole. This greatly prolongs the heat exchange time between the cooling water and the high-temperature air and improves the cooling effect on the high-temperature air. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses a high-temperature venting device.

[0027] Reference Figure 1 and Figure 2 The high-temperature venting device includes a cooling core cylinder 1, which has multiple first cooling holes 101 for gas discharge. One end of the cooling core cylinder 1 is connected to an exhaust valve 2, and the other end is connected to an exhaust inner pipe 5. The exhaust inner pipe 5 is connected to an exhaust pipe 3 at the other end of the cooling core cylinder 1.

[0028] High-temperature air flows from the exhaust pipe 3 through the inner exhaust pipe 5, then through each of the first cooling holes 101 on the cooling core tube, and finally exits from the exhaust valve 2.

[0029] Reference Figure 1 and Figure 2 The exhaust pipe 5 extends into the exhaust pipe 3. The exhaust pipe 5 and the exhaust pipe 3 are fitted with a gap and filled with heat insulation cotton (not shown in the figure). The exhaust pipe 5 and the exhaust pipe 3 are connected by a flange.

[0030] Reference Figure 1 , Figure 2 and Figure 3 A hollow flow ring chamber 4 is welded to the outer circumferential wall of the cooling core cylinder 1. A first partition plate 43 is integrally formed inside the flow ring chamber 4, which abuts against the outer wall of the cooling core cylinder 1. The first partition plate 43 divides the inner cavity of the flow ring chamber 4 into a first inlet chamber 41 and a first outlet chamber 42.

[0031] Reference Figure 2 and Figure 3 The cooling core cylinder 1 has multiple first liquid inlet channels 102 connected to the first inlet cavity 41 and multiple first liquid outlet channels 103 connected to the first outlet cavity 42.

[0032] Reference Figure 2 and Figure 3 Since the water inlet and outlet of the first liquid inlet channel 102 and the water inlet and outlet of the first liquid outlet channel 103 are all located on the outer circumferential wall of the cooling core cylinder 1, the opening of the first liquid inlet channel 102 and the first liquid outlet channel 103 during the production process will inevitably leave extra channels at the end of the cooling core cylinder 1. If these channels are not sealed, high-temperature air and cooling water will mix, resulting in chaotic operation.

[0033] Reference Figure 4 To this end, multiple pull rods 7 are installed inside the cooling core cylinder 1. Each pull rod 7 is coaxial and spaced apart within each first liquid inlet channel 102 and first liquid outlet channel 103. A plug 8 for sealing is slidably fitted onto the end of the pull rod 7, and a fastening nut 9 for pushing the plug 8 against the end face of the cooling core cylinder 1 is threaded onto the pull rod 7.

[0034] Reference Figure 4The diameter of the tie rod 7 inside the first liquid inlet channel 102 and the first liquid outlet channel 103 gradually increases along the flow direction of the cooling water inside, which helps to increase the flow rate of the cooling water and reduce pressure loss.

[0035] Reference Figure 5 Each fastening nut 9 has a star-shaped anti-loosening hole 91. The anti-loosening holes 91 of multiple fastening nuts 9 at the same end of the cooling core cylinder 1 are connected by an anti-loosening steel wire 10. Both ends of the anti-loosening steel wire 10 are welded with anti-detachment balls 11. The anti-loosening steel wire 10, together with the anti-detachment balls 11, reduces the possibility of the fastening nut 9 loosening.

[0036] Reference Figure 4 and Figure 5 The end of the pull rod 7 has a pre-reserved clamping groove 71, and the pull rod 7 has an integrally formed protruding ring 12 near the end for the block 8 to push and deform.

[0037] Workers use tools such as pliers to clamp the clamping groove 71 at the end of the pull rod 7 to ensure that the pull rod 7 remains circumferentially stationary when the fastening nut 9 is rotated.

[0038] Tighten the fastening nut 9, and the fastening nut 9 will push the plug 8 to gradually press against the end face of the cooling core cylinder 1. During this process, the plug 8 will also push against the convex ring 12, causing it to undergo a small compression deformation, thereby improving the sealing performance and reducing the possibility of cross-leakage between high-temperature air and cooling water.

[0039] Finally, the anti-detachment steel wire is passed through each fastening nut 9 and also through the pull rod 7. Finally, anti-detachment balls 11 are put on both ends of the anti-detachment steel wire. With the anti-detachment balls 11 pressed against the corresponding fastening nut 9, the anti-detachment balls 11 are welded to the anti-detachment steel wire.

[0040] Reference Figure 2 and Figure 3 The cooling core cylinder 1 and the outlet inner pipe 5 are connected by an outer cover and welded with a flow ring cylinder 6. The flow ring cylinder 6 has an integrally formed second partition plate 63 that divides its inner cavity into a second inlet cavity 61 and a second outlet cavity 62. The first liquid inlet channel 102 is connected to the second inlet cavity 61, and the first liquid outlet channel 103 is connected to the second outlet cavity 62.

[0041] An annular flow exchange chamber 51 is provided in the wall thickness of the inner outlet pipe 5 extending into the exhaust pipe 3. A plurality of second cooling holes 52 are also provided in the wall thickness of the inner outlet pipe 5, which are respectively connected to the second inlet chamber 61 and the second outlet chamber 62. The other end of the second cooling holes 52 relative to the flow ring cylinder 6 is connected to the flow exchange chamber 51.

[0042] Reference Figure 2 and Figure 3Cooling water flows into the first inlet chamber 41, then through the first liquid inlet channel 102 to the second inlet chamber 61, and then from a portion of the second cooling holes 52 into the exchange chamber 51. After the cooling water is exchanged by the exchange chamber 51, it flows into the second outlet chamber 62 through the remaining portion of the second cooling holes 52, then into the first outlet chamber 42 through the first liquid outlet channel, and finally is discharged.

[0043] The implementation principle of a high-temperature relief device according to an embodiment of this application is as follows: High-temperature air flows from the exhaust pipe 3 through the inner exhaust pipe 5, then through each of the first cooling holes 101 on the cooling core tube, and finally exits from the exhaust valve 2.

[0044] Cooling water flows into the first inlet chamber 41, then through the first liquid inlet channel 102 into the second inlet chamber 61, and then from a portion of the second cooling holes 52 into the exchange chamber 51. After the cooling water undergoes the exchange effect of the exchange chamber 51, it flows into the second outlet chamber 62 through the remaining portion of the second cooling holes 52, then into the first outlet chamber 42 through the first liquid outlet channel, and finally is discharged.

[0045] During this process, the high-temperature air and cooling water exchange heat, which greatly reduces the temperature of the high-temperature air at the exhaust valve 2, thereby ensuring that the temperature meets the requirements for long-term continuous and stable operation of the exhaust valve 2 and extending the service life of the exhaust valve 2.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
