Description

Technical Field

[0001] The utility model relates to a steam pipe network heating system. Background Art

[0002] In traditional steam pipe networks, buried pipes are buried at varying depths due to varying geographical environments. The height of the drainage outlets within the same pipe section after exiting the ground is also inconsistent, with only a small portion of pipe being elevated (over bridges, rivers, etc.). Consequently, water accumulation in low-lying areas of the buried pipes is inevitable, making it difficult to drain, creating "water plugs." This not only leads to heat loss but can also cause pipe ruptures and heating interruptions. Existing drainage methods are often inefficient, require manual intervention, and struggle to achieve rapid and thorough drainage. This problem is particularly pronounced in long-distance and large-scale steam pipe networks. In light of this, the present invention proposes a steam pipe heating system to address these issues.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example:

[0029] like Figure 1-6 As shown, this embodiment proposes a steam pipe network heating system, including a heat source point 10, a gas supply pipe 40 is provided on the heat source point 10, and an early warning component 20 is provided on the gas supply pipe 40;

[0030] The air supply pipe 40 is provided with multiple groups of control valves 30, and the control valves 30 are connected to the air supply pipe 40. Two groups of installation pipes 50 are symmetrically provided on the control valve 30, and the installation pipes 50 are connected to the air supply pipe 40. A connecting pipe 51 is provided on the installation pipe 50, and the connecting pipe 51 is connected to the inner cavity of the installation pipe 50. A detachable sealing assembly 60 is provided in the connecting pipe 51, and the connecting pipe 51 is connected to the vehicle-mounted air compressor, so that high-pressure gas enters the air supply pipe 40 to squeeze and discharge the liquid fluid.

[0031] In this case, the heat source point 10 includes but is not limited to thermal power plants, regional boiler rooms, geothermal energy, gas boilers, and electric boilers.

[0032] In this embodiment, when heating is carried out, steam is provided from the heat source point 10 to the gas supply pipe 40, and is transported to each user through the gas supply pipe 40. When it is necessary to drain the accumulated water in the gas supply pipe 40, the accumulated water area is set as a unit to be drained, and the control valves 30 on both sides of the unit to be drained are closed. At the same time, the connecting pipes 51 of the two sets of control valves 30 close to the unit to be drained are opened, that is, the sealing components 60 on the connecting pipes 51 are removed, so that the two sets of connecting pipes 51 are connected to the unit to be drained. Then, the on-board air compressor is connected to the connecting pipes 51, and high-pressure gas is injected into the connecting pipes 51 to squeeze the accumulated water in the unit to be drained out from the other set of connecting pipes 51, thereby completing the process of draining the accumulated water.

[0033] Of course, after one set of connecting pipes 51 is drained of accumulated water by the vehicle-mounted air compressor, a pipe capable of absorbing water can be placed in the other set of connecting pipes 51 to improve the effect and quality of draining accumulated water by the pipe capable of absorbing water.

[0034] Of course, after the unit to be discharged has completed the process of discharging the accumulated water, the previously disassembled sealing assembly 60 is reinstalled in the connecting pipe 51, and the two sets of control valves 30 that were previously closed are opened;

[0035] By integrating the control valve 30 and the installation pipe 50 on the air supply pipe 40, and cooperating with the detachable sealing assembly 60 and the connection with the vehicle-mounted air compressor, an efficient and flexible solution for draining accumulated water is provided. The system can, when the control valves 30 on both sides of the unit to be drained are closed, open the connecting pipe 51 close to the unit to be drained, remove the sealing assembly 60, and use the vehicle-mounted air compressor to inject high-pressure gas to effectively squeeze out the accumulated water from the air supply pipe 40. It also allows a water-absorbing pipe to be placed in another set of connecting pipes 51 to further improve the drainage effect and quality. After the accumulated water drainage process is completed, the sealing assembly 60 can be quickly reinstalled and the control valve 30 can be restored to ensure that the system quickly returns to normal operation. Segmented drainage can be achieved, which greatly improves the drainage efficiency of the steam network and enhances the convenience of operation and the safety of the system.

[0036] Specifically, the gas supply pipeline 40 is provided with multiple groups of overhead pipelines 43, a buried pipeline 41 is provided between every two groups of the overhead pipelines 43, and a fixed pipeline 42 is provided between the buried pipeline 41 and the overhead pipeline 43;

[0037] The number of the control valves 30 matches the number of the overhead pipelines 43 , and the control valves 30 are arranged on the overhead pipelines 43 .

[0038] In this embodiment, the unit to be discharged is part of the buried pipeline 41. The buried pipeline 41 is arranged below the ground, and the overhead pipeline 43 is arranged above the ground.

[0039] Specifically, the early warning component 20 includes a set of early warning electromagnetic main valves 21, a set of heating network alarm displays 22 and multiple sets of vibration sensors 221. The vibration sensors 221 are connected to the heating network alarm displays 22 via cables.

[0040] Specifically, multiple groups of vibration sensors 221 are respectively set on multiple groups of buried pipelines 41, and the early warning electromagnetic main valve 21 is set on the overhead pipeline 43 close to the heat source point 10. The early warning electromagnetic main valve 21 is also connected to the heat network alarm display 22.

[0041] In this embodiment, when the buried pipeline 41 is being monitored for early warning, if there is accumulated water in the buried pipeline 41 that has not been completely drained, the steam is likely to condense at the steam-water interface, causing a sudden change in volume, producing a popping sound, and forming vibrations. This is monitored by the vibration sensor 221, and the signal is transmitted to the heating network alarm display 22. The heating network alarm display 22 then marks out the area that needs to be drained, so as to implement a fixed-point drainage process.

[0042] Specifically, the sealing assembly 60 includes a sealing cylindrical shell 65, the inner wall of the connecting pipe 51 is provided with an internal threaded wall 53, and the outer wall of the sealing cylindrical shell 65 is provided with an external threaded wall 64. The internal threaded wall 53 and the external threaded wall 64 are threadedly matched, so that the sealing cylindrical shell 65 is connected to the inner cavity of the connecting pipe 51 for sealing.

[0043] Specifically, the connecting pipe 51 is provided with an inner wall thickening portion 54 , the inner wall thickening portion 54 is provided with a contact surface 55 , and the contact surface 55 is provided with a sealing gasket 56 ;

[0044] The sealing cylindrical housing 65 is connected in the connecting pipe 51 and contacts the sealing gasket 56 .

[0045] In this embodiment, when the sealing assembly 60 is removed from the connecting pipe 51, the sealing cylindrical housing 65 is aligned with the connecting pipe 51, and the internal threaded wall 53 and the external threaded wall 64 are threadedly engaged, so that the sealing cylindrical housing 65 is installed on the connecting pipe 51 to seal, thereby ensuring a normal heating process;

[0046] When it is necessary to perform a drainage process on the drainage unit, that is, to perform a drainage process on the buried pipe 41, the sealing cylindrical shell 65 can be removed from the connecting pipe 51 by reverse threading of the internal threaded wall 53 and the external threaded wall 64. The threaded cooperation of the internal threaded wall 53 and the external threaded wall 64 can facilitate the rapid disassembly process of the sealing cylindrical shell 65 to improve the drainage efficiency.

[0047] Specifically, the connecting pipe 51 is provided with a connecting flange 52, and the sealing cylindrical housing 65 is provided with a sealing flange 66;

[0048] The connecting flange 52 is matched with the sealing flange 66 , and the connecting flange 52 and the sealing flange 66 are connected by bolts.

[0049] In this embodiment, the connecting flange 52 and the sealing flange 66 are connected by bolts, which can further improve the stability of the connection of the sealing cylindrical shell 65 and avoid heating leakage during long-term heating.

[0050] Specifically, a sealing connection block 63 is provided at the bottom of the sealing cylindrical housing 65 , and the sealing connection block 63 is in close contact with the inner wall of the inner wall thickening portion 54 ;

[0051] An impeller 61 is provided on the sealing connection block 63, and a flow indicator 67 is provided on the top of the sealing cylindrical shell 65. A rotating shaft 62 filled with magnetic material is fixedly provided on the impeller 61, and the rotating shaft 62 is rotatably provided on the sealing connection block 63. A magnetoelectric converter is provided in the flow indicator 67, and the rotating shaft 62 cooperates with the magnetoelectric converter.

[0052] In this case, the flow display 67 is also connected to the heat network alarm display 22 via a network or other wireless connection method for real-time data transmission;

[0053] The magnetic material is mounted on the top of the rotating shaft 62 and extends into the flow indicator 67. The top of the rotating shaft 62 cooperates with the magnetoelectric converter;

[0054] In this embodiment, when measuring the flow rate of the fluid in the connecting pipe 51, the gaseous fluid flows in the connecting pipe 51, driving the impeller 61 to rotate, thereby driving the rotating shaft 62 and the magnetic material on the top of the rotating shaft 62 to rotate. The magnetic-electric converter converts the electrical signal into an electrical signal, which is transmitted to the flow display 67 for reading. The above can be referred to as a gas turbine flowmeter, which will not be described in detail here.

[0055] The cooperation between the impeller 61 and the rotating shaft 62 can facilitate real-time reading of the gaseous fluid in the connecting pipe 51, and facilitate timely query of the status of the gaseous fluid during the transportation process;

[0056] Of course, when corrosion occurs in the overhead pipeline 43, the buried pipeline 41 and the fixed pipeline 42 and leakage occurs, the gas fluid can be monitored through this monitoring method. When an abnormality occurs, a signal can be transmitted to the heating network alarm display 22 and the early warning electromagnetic main valve 21 can be closed to avoid safety accidents.

[0057] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
