Description

Technical Field

[0001] This invention relates to the field of steam condensate drainage system technology, and in particular to a large-capacity condensate drainage system. Background Technology

[0002] Steam pipelines frequently experience unstable loads, sometimes even operating at zero load or below steam saturation parameters. Under these conditions, large amounts of condensate form within the steam pipes. If this condensate cannot be discharged from the steam pipes promptly and smoothly, it will severely impact the safe and stable operation of the steam pipeline network, easily leading to water hammer and, in severe cases, damage to the pipeline. Furthermore, the discharge of condensate through drainage pipes is often accompanied by some steam overflow; the discharge outlet sometimes emits white steam and generates noise, which, without appropriate measures, can negatively impact the urban environment. Therefore, the rational design of the drainage system is of great significance for the safe operation of steam pipeline networks and the urban environment. Summary of the Invention

[0003] One of the objectives of this invention is to provide a large-capacity drainage system to solve the problem of large condensate discharge from steam pipes that cannot be discharged in a timely and smooth manner, thereby enabling timely and smooth discharge of condensate from steam pipes.

[0004] The second objective of this invention is to provide a large-capacity drainage system that solves the problem of noise caused by steam overflow during the discharge of condensate from the drainage pipe, resulting in the discharge outlet being exposed to the air. This effectively reduces the noise caused by steam overflow during the discharge of condensate from the drainage pipe.

[0005] To address the above problems, the present invention provides the following technical solution:

[0006] A high-capacity drainage system includes a drainage tee, a collection tank, a pipe cap, a drainage pipe, a double-chamber drainage well, a main steam pipe, and a drainage flow rate regulating device. The two opposite ends of the drainage tee are connected to the main steam pipe, and the lower end of the drainage tee is connected to the upper end of the collection tank. The bottom of the collection tank is sealed by the pipe cap. One end of the drainage pipe is connected to the side wall of the collection tank, and the other end is inserted into the double-chamber drainage well. A drainage flow rate regulating device is provided on the drainage pipe inside the double-chamber drainage well.

[0007] As one possible approach, a perforated plate is installed at the connection point between the hydrophobic tee and the main steam pipe.

[0008] As one possible implementation, the drainage capacity regulating device includes a first gate valve, a bypass drainage pipe, a stop valve, a throttle rod, a drainage valve, and a second gate valve; the dual-chamber drainage well includes a main drainage well and a secondary drainage well arranged side by side; one end of the drainage pipe is connected to the side wall of the collection tank, and the other end passes through the main drainage well and is inserted into the secondary drainage well; the drainage pipe in the main drainage well is sequentially equipped with a first gate valve, a stop valve, a throttle rod, and a drainage valve, wherein the first gate valve is far away from the secondary drainage well, and the drainage valve is close to the secondary drainage well; one end of the bypass drainage pipe is connected to the drainage pipe between the first gate valve and the stop valve, and the other end is connected to the drainage pipe between the drainage valve and the secondary drainage well; the bypass drainage pipe is equipped with a second gate valve.

[0009] One possible method is to use a throttle bar to adjust the amount of condensate discharged from the drain pipe.

[0010] As one possible implementation method, the first gate valve, throttle rod, shut-off valve, and steam trap are all normally open; when the condensate discharge in the steam trap is less than 1.5 t / h, the throttle rod closes the second gate valve and adjusts the condensate discharge; when the condensate discharge in the steam trap is greater than or equal to 1.5 t / h, the throttle rod opens the second gate valve and discharges the condensate.

[0011] One possible approach is to fill the drainage manhole with graded gravel filler material, which covers the drainage pipe.

[0012] As one possible approach, the graded pebble filler should be at least 30cm above the drainage pipe.

[0013] As one possible approach, a steel grating is installed on the surface of the graded pebble filler, with the aperture of the grating not exceeding the minimum particle size of the graded pebble filler.

[0014] As one feasible approach, the minimum particle size of graded pebble filler is above 20 mm.

[0015] As one possible approach, the steel grating cover is embedded in the wall of the drainage manhole on all four sides.

[0016] As one possible method, the condensate tee uses a pre-made tee, with the opposite ends of the condensate tee welded to the main steam pipe.

[0017] One possible approach is to use a thermodynamic steam trap.

[0018] Beneficial technical effects of the present invention:

[0019] The large-capacity condensate drainage system of this invention allows for the adjustment of the condensate discharge rate within the steam pipeline network via a throttle rod. When the condensate discharge rate is high, the bypass condensate drain pipe is opened, allowing both the main condensate drain pipe and the bypass condensate drain pipe to discharge condensate simultaneously. This ensures the timely and smooth discharge of condensate from the steam pipeline network, guaranteeing its safe and stable operation. The dual-chamber condensate drain integrates drainage and discharge within the well, facilitating maintenance and reducing floor space requirements. The dual-chamber condensate drain is filled with graded pebble filler, effectively reducing the noise generated when steam overflows during condensate discharge and the outlet is discharged into the air.

[0026] See Figure 1-2 This embodiment provides a large-capacity drainage system, including a drainage tee 1, a collection tank 2, a pipe cap 3, a drainage pipe 4, a double-cavity drainage well 11, a main steam pipe 14, and a drainage capacity regulating device; the two opposite ends of the drainage tee 1 are respectively connected to the main steam pipe 14, and the lower end of the drainage tee is connected to the upper end of the collection tank 2, and the bottom of the collection tank 2 is sealed by the pipe cap 3; one end of the drainage pipe 4 is connected to the side wall of the collection tank 2, and the other end is inserted into the double-cavity drainage well 11; a drainage capacity regulating device is provided on the drainage pipe 4 inside the double-cavity drainage well 11.

[0027] Condensate in the main steam pipe 14 enters the collection tank 2 through the drain tee 1; condensate in the collection tank 2 is discharged into the double-chamber drain well 11 through the drain pipe 4, and the discharge rate of condensate in the collection tank 2 is regulated by the drain discharge rate regulating device.

[0028] In this embodiment, a perforated plate 5 is provided at the connection between the drain tee 1 and the main steam pipe 14. The function of the perforated plate 5 is to prevent impurities in the main steam pipe 14 from falling into the drain pipe 4.

[0029] In this embodiment, the drainage capacity regulating device includes a first gate valve 6, a bypass drainage pipe 7, a stop valve 8, a throttle rod 9, a drainage valve 10, and a second gate valve 15; the dual-chamber drainage well 11 includes a drainage main well and a drainage auxiliary well arranged side by side; one end of the drainage pipe 4 is connected to the side wall of the liquid collection tank 2, and the other end passes through the drainage main well and is inserted into the drainage auxiliary well; the drainage pipe 4 in the drainage main well is sequentially provided with the first gate valve 6, the stop valve 8, the throttle rod 9, and the drainage valve 10, wherein the first gate valve 6 is far away from the drainage auxiliary well, and the drainage valve 10 is close to the drainage auxiliary well; one end of the bypass drainage pipe 7 is connected to the drainage pipe 4 between the first gate valve 6 and the stop valve 8, and the other end is connected to the drainage pipe 4 between the drainage valve 10 and the drainage auxiliary well; the bypass drainage pipe 7 is provided with the second gate valve 15.

[0030] In this embodiment, the first gate valve 6, the throttle rod 9, the shut-off valve 8, and the steam trap 10 are all normally open. The throttle rod 9 adjusts the amount of condensate discharged from the steam trap 4. When the amount of condensate discharged from the steam trap 4 is less than 1.5 t / h, the throttle rod 9 closes the second gate valve 15 and adjusts the amount of condensate discharged. When the amount of condensate discharged from the steam trap 4 is greater than or equal to 1.5 t / h, the throttle rod 9 opens the second gate valve 15 and discharges the condensate.

[0031] In this embodiment, the drainage auxiliary well is filled with graded pebble filler 13, which covers the drain pipe 4. The noise generated by condensate and overflowing steam in the drain pipe 4 is gradually reduced by the graded pebble filler 13.

[0039] In this embodiment, the large-capacity condensate drainage system adjusts the condensate discharge rate within the steam pipeline network via a throttle rod 9. When the condensate discharge rate is high, the bypass condensate drain pipe is opened, allowing both the main condensate drain pipe and the bypass condensate drain pipe to discharge condensate simultaneously, ensuring timely and smooth discharge of condensate from the steam pipeline network and guaranteeing its safe and stable operation.
