Description

Technical Field

[0001] This utility model relates to the technical field of blast furnace gas residual pressure power generation turbines, specifically a cleaning device for blast furnace gas residual pressure power generation turbines. Background Technology

[0002] The blast furnace gas pressure recovery turbine is the core equipment of the blast furnace gas pressure recovery turbine power generation unit. Its working principle is as follows: High-pressure gas (typically 0.2-0.3 MPa) generated during blast furnace smelting drives the turbine impeller to rotate, converting the pressure energy of the gas into mechanical energy. This mechanical energy is then converted into electrical energy by a generator, realizing the recovery and utilization of pressure recovery energy. In the blast furnace gas pressure recovery power generation system, the turbine, as the core equipment, directly affects the energy recovery efficiency and equipment lifespan. However, during long-term operation, the turbine blades easily absorb dust, tar, and other impurities from the gas, leading to frequent ash and scale buildup. Ash and scale buildup not only reduces the aerodynamic performance of the blades and increases operating resistance, but may also cause increased equipment vibration, decreased efficiency, and even threaten the safe and stable operation of the unit.

[0003] Currently, the cleaning devices commonly used for cleaning turbine blades mainly consist of a cleaning agent tank, a water pump, and nozzles. While this traditional cleaning method can effectively remove dirt, the blades must be rinsed a second time with clean water after cleaning with the cleaning agent to avoid residual cleaning agent causing corrosion or other damage to the blades. This requires workers to carry an additional water tank during cleaning operations, which not only increases the workload and carrying difficulty but also reduces cleaning efficiency and prolongs equipment downtime for maintenance. Therefore, a cleaning device for blast furnace gas residual pressure power generation turbines is needed. Utility Model Content
