Description

Technical Field

[0001] The invention relates to the field of wastewater treatment, in particular to a wastewater filtering mechanism for a thermal power plant. Background Art

[0002] A thermal power plant is a factory that uses coal, oil, and natural gas as fuel to produce electricity. Its basic production process is that the fuel burns in the boiler to heat water to make 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, and then the turbine drives the generator to rotate, converting the mechanical energy into electrical energy. Modern power plants mostly use program control to improve the level of automation. Program control is to divide a large number of scattered operations in the production process into several regular programs according to the process flow of auxiliary machines and thermal systems, and combine protection and interlocking conditions so that the operator can automatically complete the operation of the control system through a few switch buttons. With the increasing expansion of computer applications, especially the development of microcomputers and microprocessors, the automation of modern thermal power plants has realized a hierarchical integrated control method based on minicomputers, microcomputers, and microprocessors.

[0003] During the daily operation of thermal power plants, various types of sewage and wastewater are generated. The sewage and wastewater mainly include acid and alkaline sewage from the chemical water treatment workshop, ash flushing water generated by the electrostatic precipitator ash flushing system, boiler room slag flushing sewage, boiler regular sewage, circulating water system sewage, coal transportation system flushing water, oily sewage generated by the oil depot and domestic sewage in the plant area. The main pollutants in the sewage are suspended solids, petroleum and a small amount of organic matter. The direct discharge of wastewater from thermal power plants has a great impact on the environment. Therefore, it is necessary to treat the wastewater from thermal power plants. When treating the wastewater from thermal power plants, filters are required to filter the solid matter in the wastewater.

[0004] In the authorized Chinese utility model patent "Announcement No.: CN216963699U, Name: A filter device for wastewater discharge from a thermal power plant", the spiral blades are driven to rotate by rotating the pipe, so that the wastewater in the drainage pipe is continuously pushed forward to prevent the wastewater from depositing. Since the filter element needs to be cleaned frequently, and the existing filter element requires multiple screws to be fastened, it takes a long time to disassemble and assemble, which affects the cleaning efficiency. At this time, the installation component can be retracted by a spring, which facilitates the disassembly and assembly of the filter component, thereby achieving the effect of increasing the disassembly and assembly speed. In the above application, spiral blades are used to push the wastewater forward to prevent pipe blockage, but the sediment in the wastewater easily blocks the filter screen. In the above application, the blocked filter screen is solved by replacing the filter element, which is troublesome to operate and needs to be stopped for processing when replacing the filter element, affecting the efficiency of wastewater filtration.
