Description

Technical Field

[0001] The utility model relates to the field of heat exchange components, in particular to a heat exchange component for utilizing waste heat in a thermal power plant. Background Art

[0002] A thermal power plant, also known as a thermal power plant, is a factory that uses combustibles such as coal as fuel to produce electricity. Its basic production process is: when the fuel burns, 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 thermal energy into mechanical energy. The turbine then drives the generator to rotate, converting mechanical energy into electrical energy. A thermal power plant will produce a large amount of high-temperature flue gas during operation. In order to increase the utilization rate of energy, the staff will use heat exchange components to perform heat exchange treatment on the high-temperature flue gas generated during the operation of the thermal power plant, which brings convenience to the staff's subsequent flue gas treatment work and increases the utilization rate of energy.

[0003] However, the current heat exchange components still have some shortcomings. For example, the existing heat exchange components have poor anti-clogging function, which leads to the blockage of the pipeline when the high-temperature flue gas circulates in the pipeline for a long time, thereby causing certain interference to the subsequent heat exchange efficiency of the heat exchange component and the exhaust speed of the flue gas. As a result, there are certain usage defects. There is a large amount of dust in the flue gas generated by coal combustion, and common heat exchange components mostly use curved pipes to transport the medium. Therefore, the dust carried in the flue gas will slowly become clogged as the pipeline is used for a longer time.

[0004] Therefore, it is urgent to improve this shortcoming. The utility model studies and improves the existing structural deficiencies and provides a heat exchange component for utilizing waste heat in a thermal power plant. Utility Model Content
