Description

Technical Field

[0001] The utility model relates to the technical field of vaporizing flue, in particular to a cooling device applicable to a vaporizing flue. Background Technique

[0002] The converter vaporizing flue, also known as a waste heat boiler, is one of the main auxiliary equipment for converter steelmaking. When this equipment is working, it needs to collect high-temperature flue gas to the greatest extent, withstand the highest furnace gas temperature and severe and frequent temperature changes. At the same time, the working conditions are the worst and it is most likely to bond and splash molten steel slag. Therefore, the role of its cooling device is particularly prominent. After retrieval, the patent with the publication number CN208617920U discloses a cooling compensation device for a converter vaporizing flue, which is characterized by including a converter vaporizing flue, a temperature sensor, a spraying system and a control system. A number of temperature sensors are provided and are arranged at intervals on the outer wall of the converter vaporizing flue. The spraying system includes several groups, and the spraying system is composed of a drain pipe and a nozzle. The drain pipe is provided with a solenoid valve. The drain pipe is arranged in an arc shape on the outside of the converter vaporizing flue. The nozzle is arranged on the drain pipe facing the converter vaporizing flue and is communicated with the drain pipe. The drain pipe is communicated with a water inlet pipe. The control system includes a programmable controller. The programmable controller is signal-connected to the temperature sensor and is control-connected to the solenoid valve. It monitors the temperature of the outer wall of the flue pipe in real time. When the temperature rises abnormally, cooling compensation measures are taken in time through the controller. In addition to the original internal vaporization cooling method, external drain pipe spraying cooling is added to avoid the explosion of the flue pipe caused by the interruption of the water circulation due to blockage. However, it is not convenient to adjust the external cooling water volume according to the internal temperature change, and it is easy to have a situation of excessive water consumption, which is relatively wasteful. Therefore, a cooling device applicable to a vaporizing flue is designed, which is convenient to adjust the external cooling water volume according to the internal temperature change and avoid the situation of excessive waste of cooling water volume.

The external cooling structure includes a plurality of external thread cooling pipes 6 that are spaced and cross-wound around the outer wall of the vaporization flue 1. Flow control components and direction control components are respectively installed at both ends of the external thread cooling pipe 6. The internal temperature detection structure includes an internal thread cooling pipe 7 that is embedded and wound on one side of the vaporization flue 1 near the outlet end 3.

Through the two temperature control valves 11, it is convenient to observe the temperature inside the outlet end 3 side and the temperature change after entering and leaving, and transmit the signal to the controller. If the temperature of the outlet end 3 side in the vaporization flue 1 is too high, a signal is given to the plurality of flow control components to increase the number of external thread cooling pipes 6 through which cooling water passes. When the temperature drops to a certain value, the signal is also transmitted to the plurality of flow control components to reduce the number of external thread cooling pipes 6 through which cooling water passes.

[0024] Specifically, annular water distribution headers 4 and annular water collection headers 5 are respectively arranged on both sides of a plurality of externally threaded cooling pipes 6.

[0025] Specifically, the flow control member and the flow direction control member are respectively arranged as a shut-off valve 8 and a check valve 9. Through the shut-off valve 8, it is convenient to control the flow rate of the cooling water flowing into the externally threaded cooling pipes 6. Through the check valve 9, it is convenient to only allow the water passing through the externally threaded cooling pipes 6 to flow towards the annular water collection header 5.

[0026] Specifically, the internally threaded cooling pipe 7 is arranged on one side inside the vaporization flue 1 and is in a smooth toroidal surface with the inner side wall of the vaporization flue 1, so as not to affect the structure of the inner wall of the vaporization flue 1 and ensure the smooth progress of vaporization.
