Description

Technical Field

[0001] The utility model belongs to the technical field of industrial wastewater, and in particular relates to an industrial wastewater waste heat utilization device. Background Art

[0002] Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to the wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. Industrial wastewater is of various types and complex in composition. For example, electrolytic salt industrial wastewater contains mercury, heavy metal smelting industrial wastewater contains lead, cadmium and other metals, electroplating industrial wastewater contains cyanide and chromium and other heavy metals, petroleum refining industrial wastewater contains phenol, pesticide manufacturing industrial wastewater contains various pesticides, etc. Since industrial wastewater often contains a variety of toxic substances, polluting the environment is very harmful to human health. Therefore, it is necessary to develop comprehensive utilization and turn harm into benefit. According to the composition and concentration of pollutants in the wastewater, corresponding purification measures should be taken for disposal before it can be discharged. The treatment of industrial wastewater is more important than the treatment of urban sewage. Industrial wastewater will generate a lot of heat. The heat energy of industrial wastewater can be reused, and waste heat utilization equipment is required.

[0003] During use, common waste heat utilization devices bring heat-containing industrial wastewater into contact with pipes, thereby heating the liquid in the pipes and achieving the purpose of waste heat utilization.

[0004] However, due to the short contact time between industrial wastewater and pipelines, the heating time is limited, resulting in a large amount of heat energy still in the discharged wastewater, causing waste of heat energy and failure to maximize the utilization of heat energy. Therefore, we provide an industrial wastewater waste heat utilization device. Utility Model Content
