Description

Technical Field

[0001] The utility model relates to the technical field of urban heating, in particular to a steam pipeline drainage and dewatering device. Background Art

[0002] Condensate will be generated during the steam pipeline transportation process. If the condensate is not discharged in time, water hammer will occur and cause pipeline damage. Therefore, drain devices are usually installed at low points along the steam pipeline and in front of vertical rising pipelines. When the high-temperature and high-pressure condensate discharged by the drain device is discharged into the atmosphere, since the condensate temperature is higher than the saturation temperature of water under normal pressure, part of the water vaporizes into steam to lower the condensate temperature, which will cause the appearance of flash steam (that is, the appearance of white fog). Since the steam pipeline is partially laid overhead or directly buried along the roadway or sidewalk, and the drain well connected to the steam pipeline is usually located on the roadway or sidewalk, the white fog generated during the drainage process will affect the passage of vehicles and pedestrians, causing certain safety hazards.

[0003] In view of this, overcoming the defects of the prior art is an urgent problem to be solved in the field of this technology. Utility Model Content

[0008] Preferably, the copper coil 4 is welded or sleeved to the drain pipe 1 .

[0009] Preferably, the interface between the copper coil 4 and the drain pipe 1 is sealed.

[0010] Preferably, the number of turns of the copper coil 4 is 10-20.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] In the description of the present invention, the terms "inside", "outside", "longitudinal", "lateral", "upper", "lower", "top", "bottom" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0026] In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] In order to solve the technical problem that the drain discharge link of the steam pipeline in the heating process of the prior art is prone to produce white fog, this embodiment provides a steam pipeline drain whitening device, such as Figure 1-Figure 2 As shown, it includes: a drain pipe 1, a steam trap 2, a valve 3 and a copper coil 4. In terms of connection, the drain pipe 1 is fixed by a fixing mechanism 7. One end of the drain pipe 1 is connected to the steam pipe 5, and the other end extends to the inside of the drain well 6 and is connected to the copper coil 4. The copper coil 4 is located at the wellhead of the drain well 6. In specific implementation, the copper coil 4 and the drain pipe 1 are welded or sleeved. At the same time, when connecting, it is necessary to ensure that the interface between the copper coil 4 and the drain pipe 1 is in a sealed state to prevent condensate from leaking, so that the condensate can completely pass through the copper coil 4. The steam trap 2 and the valve 3 are respectively connected in series to the drain pipe 1. In terms of the series connection sequence, preferably, the valve 3 is arranged at the front end of the steam trap 2.

[0030] In this embodiment, by setting up the copper coil 4, the heat exchange area between the condensate and the outside air can be increased, which is beneficial to the heat exchange between the condensate and the air, thereby achieving the effect of reducing the temperature and pressure of the condensate, and achieving the situation that no flash evaporation occurs when the condensate is discharged from the copper coil 4, thereby finally achieving the technical effect of de-whitening.

[0031] In some of the optional implementations, in order to achieve a more complete heat exchange process between condensate and air, in actual application, the number of turns of the copper coil 4 should not be too small and the winding angle should not be too large. Preferably, the number of turns of the copper coil 4 is 10-20 turns, and the winding angle of the copper coil 4 is 5-15 degrees.

[0032] like Figure 3 As shown, Figure 3 yes Figure 1-Figure 2 Schematic diagram of the structure of the copper coil.

[0033] In order to enhance the application scope of the device and ensure that the device meets the application scenarios of small, neutral and large heating systems, in actual application, the steam trap 2 and the valve 3 can be flexibly selected as needed. Specifically, the steam trap 2 can be a mechanical steam trap, a thermostatic steam trap or a thermodynamic steam trap. At the same time, the valve 3 can be a shut-off valve, a check valve, a safety valve, a diverter valve or a regulating valve.
