The embodiment of the invention discloses a hot air backflow device for an air-cooled generator unit of a power station of an industrial and mining workshop. The hot air backflow device comprises a boiler room, a steam turbine room and an air cooling platform which are connected in sequence, wherein the boiler room is connected with an air heater for providing combustion-supporting air for the boiler room, an exhaust fan is arranged above the air cooling platform, and an air outlet of the exhaust fan is connected with an air suction opening of the air heater through a ventilation pipeline. According to the hot air backflow device, the exhaust fan is arranged above the air cooling platform, the air outlet of the exhaust fan is connected with the air suction opening of the air heater through the ventilation pipeline, so that a more excellent working environment is created for the air cooling platform under the condition that the function of the exhaust fan is not affected, hot air above the air cooling platform is sucked away while the exhaust fan works, and the hot air backflow problem is effectively solved; and released hot air is provided to the air heater to raise the temperature of combustion-supporting air, the steam extraction amount of the air heater can be reduced, the saved steam plays a more important working role, and therefore the economical efficiency of the air-cooled generator unit is greatly improved.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of industrial and mining equipment, and in particular to a hot air return device for an air cooler of an industrial, mining, power plant, and power station. Background technique [0002] In some large industrial and mining plants, there are electrical equipment such as power stations. For power stations, a part of the core is used for cooling. The specific implementation is to leave many square slots at the junction of the stator core and the casing of the generator, and the strong wind flow formed when the axial flow blades on the generator rotor are running flows through the square slots between the stator core and the casing , the coil discharges the heat from the body to achieve the purpose of heat dissipation, which corresponds to the water-cooled unit in the generator set. [0003] The air-cooled unit has largely solved the problem of rich coal and poor water in the northern regi...
