Regarding the related technologies mentioned above, the applicant believes that when water vapor passes through the steam turbine and moves along the pipeline, impurities will gradually adhere to the inner wall of the pipeline, and the impurities on the inner wall of the pipeline need to be cleaned. When the inner wall of the pipeline is cleaned, the heat recovery efficiency of the thermal power plant will deteriorate

Description
technical field [0001] The present application relates to the field of waste heat recovery equipment, in particular to a waste heat recovery device for waste steam and wastewater. Background technique [0002] A thermal power plant uses fuel combustion to heat tap water first. After the tap water is heated, steam will be generated. The steam is transmitted to the steam turbine through the pipeline, and the steam turbine rotates to generate electricity. [0003] In the related technology, after the steam generated by the thermal power plant passes through the steam turbine, the steam still carries some heat, and the heat carried by the steam is recovered through the heat recovery pipeline. The heat carrier passing through the heat recovery pipeline is usually tap water, which carries heat The water vapor is heat-exchanged, so as to recover the heat in the water vapor. [0004] Regarding the related technologies mentioned above, the applicant believes that when water vapor pa...
