Description

Technical Field

[0001] The utility model relates to the technical field of thermal power plant cleaning, in particular to a cleaning structure for a power generation sewage tank in a thermal power plant. Background Art

[0002] A thermal power plant is a plant that uses combustibles (such as coal) as fuel to produce electricity. Its basic production process is: when the fuel is burned, it heats water to generate steam, converting the chemical energy of the fuel into thermal energy. The steam pressure drives the turbine to rotate, converting the thermal energy into mechanical energy. The turbine then drives the generator to rotate, converting the mechanical energy into electrical energy.

[0003] Ash flushing water from power plants is one of the main sources of pollution in thermal power plants and coal-fired power plants. It generally refers to the water used to flush slag and discharge ash from dust collectors. It is usually discharged after sedimentation in the ash field. Ash flushing water accounts for about 40% to 50% of the total wastewater. The types of pollutants in ash flushing water and their content are greatly affected by the type of coal, coal combustion method and dust removal method.

[0004] There are many impurities in the ash flushing water. Generally, chemicals are added to make the particles flocculate quickly, so as to quickly remove the particles in the sewage. The existing power plant sewage treatment equipment currently has a treatment tank. The treatment tank occupies a small space and is widely used. However, the sewage treatment tank is not convenient for handling impurities on the inner wall of the tank after long-term use. In view of this, this case came into being. Utility Model Content
