Description

Technical Field

[0001] The utility model relates to the technical field of railway transportation, in particular to a frozen coal pyrolysis device for railway freight cars. Background Art

[0002] In winter, especially in areas with lower temperatures, when transporting coal by train, the coal is easily frozen to the inner wall of the carriage due to the low temperature. The problem of frozen coal brings great difficulties to the loading and unloading of coal and easily affects the transportation efficiency.

[0003] Most thermal power plants in northern China use closed spaces such as thawing warehouses or large thawing sheds to thaw frozen coal by heating the air. However, using closed spaces to heat the air to thaw the frozen coal requires investment in the construction of basic facilities such as thawing warehouses, which is too expensive. At the same time, heating the air in a closed space makes it difficult to ensure uniform heating and flow of the air, which can easily lead to slow thawing of some frozen coal, thereby affecting the thawing efficiency and prolonging the thawing time, which can easily affect subsequent power generation work. Utility Model Content

[0007] The jet component includes a steam main pipe arranged in front of the support column, a surface of the steam main pipe facing the steam curtain wall is connected to a plurality of steam branch pipes, a plurality of steam branch pipes are connected to a plurality of steam nozzles on a side facing the track, and also includes a throttle valve and an electric valve fixedly installed on the steam main pipe in sequence;

[0008] The fixing member comprises a plurality of fixing plates fixedly mounted on the surfaces of the two supporting columns on opposite sides, and the surfaces of the plurality of fixing plates are fixedly mounted with fixing columns whose other ends are connected to the surfaces of the corresponding steam branch pipes.

[0009] The beneficial effects of the utility model are: by using a thawing component to quickly liquefy high-temperature, high-pressure steam and release a large amount of heat, the bottom and sides of the freight car can be quickly heated, so that the temperature of the car rises to 35-50 degrees Celsius, and the car and the frozen coal can be quickly melted and separated without a closed space. The device is suitable for high-temperature and high-pressure steam with a gas source pressure of 1.6-0.9 MPa and a temperature of 230-150 degrees Celsius.

Among them, the steam flowing inside the steam main pipe uses the steam generated by the power plant due to power generation, so that the device does not need to be equipped with an additional steam heating device.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.
