Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline connection, and in particular relates to a multi-channel integrated steam recovery pipeline connection device. Background Art

[0002] As global energy resources become increasingly scarce, energy conservation and cost reduction have become the most pressing tasks for all enterprises. However, a large number of industrial boilers and power plant boilers equipped with deaerators and boiler expansion vessels and drain expansion vessels in their steam-water systems generate large amounts of low-pressure steam and flash steam (exhaust steam) that are discharged during operation, causing significant energy loss and waste. The economic value of recycling this valuable exhaust steam is significant. Properly recycling and utilizing this valuable exhaust steam can have significant economic value.

[0003] In the existing technology, heat recovery of the exhaust steam is achieved by adding steam recovery equipment at the end of the process. Usually, a single steam recovery equipment can meet the steam recovery needs of multiple equipment. When in use, multiple steam exhaust pipes are connected to the same steam recovery equipment. Due to the high temperature characteristics of steam, stainless steel pipes are often used for steam transmission pipes. When multiple exhaust equipment are connected to the same steam recovery equipment, the rigid stainless steel pipe is often interfered with by other exhaust equipment when connecting to the main pipe, resulting in very strict design accuracy of the pipeline and relatively time-consuming and labor-intensive installation.

[0004] To this end, we propose a multi-channel integrated steam recovery pipe connection device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problems in the prior art of high pipeline connection precision and time-consuming and labor-intensive operation when multiple pipelines are centrally connected to the same steam recovery equipment, and to propose a multi-channel integrated steam recovery pipeline connection device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Multi-channel integrated steam recovery pipe connection device, including:

[0008] The main pipe has multiple mounting parts, both ends of the main pipe are connected, one end of the main pipe is provided with a flange, and the other end is provided with a filter structure;

[0009] Multiple branch pipes are used to connect steam pipes with different gas sources. The branch pipes include a sealing ring, a pipe body and a connecting pipe. One end of the pipe body is fixedly connected to the sealing ring, and the other end is connected to the connecting pipe through an adjustment structure. The sealing ring is arranged on the mounting part for sealing rotation and can be freely adjusted around the axis of the mounting part. A limiting structure for stabilizing the position of the branch pipe is provided between the branch pipe and the mounting part, and a one-way air intake structure is provided in the pipe body.

[0010] Preferably, the mounting portion includes two sealing disks, and annular grooves are provided on the facing sides of the two sealing disks. The sealing rings are rotatably connected to the annular grooves. The circumference of the main pipe is provided with multiple openings for air intake, and the openings are located between the two sealing disks.

[0011] Preferably, the filtering structure includes a slip ring, a threaded plug and a connecting pipe with multiple air inlet windows. The slip ring is coaxially arranged with the threaded plug and fixed by the connecting pipe. A filter is installed in the air inlet window, and the threaded plug is sealed with the main pipe thread.

[0012] Preferably, the outer diameter of the slip ring is larger than the outer diameter of the connecting pipe, and the slip ring is sealed and adapted to the inner diameter of the main connecting pipe. After the threaded plug is screwed into the main connecting pipe, an air intake space connected to the opening is formed between the connecting pipe and the main connecting pipe.

[0013] Preferably, the adjustment structure includes a sealing clamp fixedly provided at the end of the tube body, a sealing gasket fixedly provided at the end of the docking tube and movably connected to the sealing clamp, the outer port of the sealing clamp is larger than the outer diameter of the docking tube, and the outer peripheral surface of the sealing clamp is threadedly connected to a plurality of adjustment rods that are against the side wall of the sealing gasket.

[0014] Preferably, the limiting structure includes a ring slidably mounted on the tube body, a spring is provided between the ring and the sealing ring, a plurality of evenly distributed notches are provided on the outer peripheral surface of the sealing disk, and a limiting rod adapted to the notches is fixedly provided on the side wall of the ring.

[0015] Preferably, the one-way air intake structure includes an air intake pipe fixedly arranged in the tube body, a blocking piece is provided at the output end of the air intake pipe, and a second spring is provided between the blocking piece and the air intake pipe.

[0016] Preferably, the end face of the air inlet pipe has an inner chamfer, and the outer edge of the blocking piece is provided with an outer chamfer matching the inner chamfer.

[0017] To sum up, the technical effects and advantages of the utility model are as follows: the multi-channel integrated steam recovery pipe connection device, through multiple rotatable branch pipes, can freely adjust the installation angle of the branch pipes when docking different exhaust equipment, and is used to adapt to exhaust pipes extending in different directions, and by setting an adjustment structure, the docking axis position can be adjusted in a small range when the pipes are docked, reducing the difficulty of connection.

[0018] By setting up multiple branch pipes, each of which is equipped with a one-way air intake structure, different numbers of steam intake pipes can be flexibly connected according to actual needs. The idle branch pipes will not leak under the restriction of the one-way air intake structure. When the steam system is expanded or adjusted, there is no need to replace the entire connection device. It is only necessary to simply increase or decrease the pipe connections, which greatly saves time and cost. The appropriate number of steam intake pipes can be connected according to needs.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] Reference Figure 1-4 The multi-channel integrated steam recovery pipe connection device includes a main pipe 1 and multiple branch pipes 2. The main pipe 1 is connected to the steam recovery equipment, and the branch pipes 2 are connected to the steam discharge pipes of the boiler, deaerator, etc.

[0028] The main pipe 1 has multiple mounting parts, which are evenly distributed along the axial direction of the main pipe 1. Both ends of the main pipe 1 are connected. A flange 11 is provided at one end of the main pipe 1 and a filter structure 12 is installed at the other end. The flange 11 is used to connect the air inlet pipe of the steam recovery equipment. When the filter structure 12 is in working condition, the end of the main pipe 1 is closed, and the steam input into the main pipe 1 can be filtered to reduce the risk of impurities entering the steam recovery equipment.

[0029] Multiple branch pipes 2 are used to connect steam pipes from different gas sources. The branch pipe 2 includes a sealing ring 21, a pipe body 22 and a connecting pipe 23. One end of the pipe body 22 is fixedly connected to the sealing ring 21, and the other end is connected to the connecting pipe 23 through an adjustment structure. Through the adjustment structure, the axial position of the connecting pipe 23 can be fine-tuned. When connecting to the steam discharge pipe, a larger operating range can be obtained, which facilitates the connecting and installation of the pipeline and reduces the difficulty of installation.

[0030] Reference Figure 1-5 The adjustment structure includes a sealing clamp 24 fixedly arranged at the end of the tube body 22, and a sealing gasket 25 fixedly provided at the end of the connecting tube 23 with the sealing clamp 24 for sealing and movably connection. The diameter of the sealing gasket 25 is smaller than the inner diameter of the sealing clamp 24, and the outer port of the sealing clamp 24 is larger than the outer diameter of the connecting tube 23. The sealing gasket 25 can move in a small range within the sealing clamp 24, thereby changing the axial position of the connecting tube 23. When connecting multiple steam exhaust pipes, there may be installation position interference between the multiple steam exhaust pipes. By adjusting the axial position of the connecting tube 23, the installation difficulty can be reduced, and the outer circumferential surface of the sealing clamp 24 is threadedly connected to a plurality of adjusting rods 26 that are against the side walls of the sealing gasket 25. The side walls of the sealing gasket 25 are pressed and limited by the adjusting rods 26 to ensure the stability of the sealing gasket 25 after the position is adjusted.

[0031] The sealing ring 21 is arranged on the mounting portion for sealing rotation and its position can be freely adjusted around the axis of the mounting portion. By rotating the sealing ring 21, the direction of the branch pipe 2 can be controlled, so that the branch pipe 2 can be connected to the steam exhaust pipes led out in different directions, which has stronger applicability and higher installation flexibility.

[0032] Reference Figure 1-5 The mounting portion includes two sealing disks 13, and an annular groove 14 is provided on the facing side of the two sealing disks 13. The sealing ring 21 is sealed and rotatably connected with the annular groove 14 to ensure the sealing between the sealing ring 21 and the annular groove 14 and reduce the risk of steam leakage. The main pipe 1 is provided with a plurality of openings 15 for air intake on its circumference. The opening 15 is located between the two sealing disks 13 to ensure that the branch pipe 2 can maintain communication with the inside of the main pipe 1 through the opening 15 when it is rotated to any position, so that multiple steam exhaust devices can collect steam in the main pipe 1 and transport it to the steam recovery device.

[0033] Reference Figure 1-5 The filtering structure 12 includes a slip ring 121, a threaded plug 122 and a connecting pipe 124 with a plurality of air inlet windows 123. The slip ring 121 and the threaded plug 122 are coaxially arranged and fixed by the connecting pipe 124. A filter screen 125 is installed in the air inlet window 123, and the threaded plug 122 is threaded and sealed with the main pipe 1. When in use, one end of the slip ring 121 is inserted into the main pipe 1, and the threaded plug 122 is sealed and docked with the main pipe 1. The steam in the branch pipe 2 is filtered through the filter screen 125, enters the interior of the connecting pipe 124, and is output from one end of the main pipe 1 connecting flange 11 through the center hole of the slip ring 121. When the filter screen 125 needs to be cleaned, there is no need to disconnect the branch pipe 2 from the steam exhaust pipe. By rotating the threaded plug 122, the threaded plug 122 can be removed to remove the slip ring 121 and the connecting pipe 124, and the filter screen 125 can be cleaned.

[0034] Reference Figure 2 The outer diameter of the slip ring 121 is larger than the outer diameter of the connecting pipe 124, and the slip ring 121 is sealed and adapted to the inner diameter of the main connecting pipe 1. After the threaded plug 122 is screwed into the main connecting pipe 1, an air intake space connected to the opening 15 is formed between the connecting pipe 124 and the main connecting pipe 1, ensuring that the input steam is blocked by the slip ring 121 and the threaded plug 122, and is collected in the air intake space and passes through the air intake window 123, ensuring that the steam is effectively filtered.

[0035] A limiting structure for stabilizing the position of the branch pipe 2 is provided between the branch pipe 2 and the mounting portion. The limiting structure can ensure that the branch pipe 2 remains stable after the direction is adjusted, and a one-way air intake structure is provided in the pipe body 22 to ensure that steam can only be input from the branch pipe 2 to the main pipe 1, limiting the flow of steam in one direction. The branch pipe 2 in the idle state will not leak steam, and different numbers of steam discharge pipes can be flexibly connected according to actual needs. When the steam system is expanded or adjusted, there is no need to replace the entire connection device, and only the pipe connections need to be simply increased or decreased, which greatly saves time and cost.

[0036] Reference Figure 1-3 and Figure 6 The limiting structure includes a collar 27 that is slidably sleeved on the tube body 22. A spring 271 is provided between the collar 27 and the sealing ring 21. The spring 271 is a tension spring. A plurality of evenly distributed notches 131 are provided on the outer circumference of the sealing disk 13. A limiting rod 272 that matches the notch 131 is fixedly provided on the side wall of the collar 27. Under the tension of the spring 271, the limiting rod 272 on the collar 27 is stuck in the notch 131, and the branch pipe 2 cannot be rotated to change its direction, thereby limiting the direction of the branch pipe 2. When adjusting the direction, the collar 27 needs to be pulled outward to disengage the limiting rod 272 from the notch 131.

[0037] Reference Figure 6The one-way air intake structure includes an air intake pipe 28 fixedly arranged in the pipe body 22, and a sealing piece 281 is provided at the output end of the air intake pipe 28. A spring 282 is provided between the sealing piece 281 and the air intake pipe 28. Under the pulling force of the spring 282, the sealing piece 281 is tightly fitted with the output end of the air intake pipe 28, and the steam outside the air intake pipe 28 cannot enter the air intake pipe 28. When steam is input into the branch pipe 2, the steam pressure pushes open the sealing piece 281, and the steam enters the main pipe 1 through the air intake pipe 28.

[0038] Reference Figure 6 The end face of the air inlet pipe 28 has an inner chamfer, and the outer edge of the blocking piece 281 is provided with an outer chamfer that matches the inner chamfer. The combination of the inner chamfer and the outer chamfer can increase the sealing effect of the blocking piece 281 and improve the air tightness.

[0039] Working principle:

[0040] During use, different numbers of steam exhaust pipes can be flexibly connected according to actual needs. When the steam exhaust pipe is connected to the butt joint pipe 23, the collar 27 is first pulled outward to disengage the limiting rod 272 from the notch 131, and the branch pipe 2 is rotated to a suitable position. After releasing the collar 27, the spring 1 271 is reset. Under the pulling force of the spring 1 271, the limiting rod 272 on the collar 27 is stuck in the notch 131, and the branch pipe 2 cannot be rotated to change its direction, thereby limiting the direction of the branch pipe 2.

[0041] Adjust the adjusting rod 26 outward to expose enough space for the sealing gasket 25 to move, so that the butt joint pipe 23 and the steam exhaust pipe are conveniently connected in a coaxial state, reducing the position deviation affecting the installation when the rigid pipes are connected. After the installation is completed, tighten the adjusting rod 26 to keep the position of the sealing gasket 25 stable.

[0042] The branch pipe 2 can maintain communication with the inside of the main pipe 1 through the opening 15, so that multiple steam discharge devices can collect steam in the main pipe 1. The steam in the branch pipe 2 is filtered through the filter 125, enters the inside of the connecting pipe 124, and is output from one end of the main pipe 1 connecting flange 11 through the center hole of the slip ring 121 to the steam recovery device.
