Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas field exploitation, in particular to a self-floating U-shaped heat exchanger used in an oil pool. Background Art

[0002] Wastewater, waste oil and other waste liquids are often generated during the production processes of chemical, petroleum, pharmaceutical, food processing, textile, papermaking and other industries. Such waste liquids are usually temporarily stored in oil pools. They may contain various organic matter, inorganic salts, heavy metals, suspended solids and other pollutants, and need to be purified before they can be discharged or used. During the purification process, there is a common demand for heat exchange in open-air oil pools or sewage pools.

[0003] However, traditional heat exchange methods usually use fixed heat exchangers, which have great limitations when facing these special environments: insufficient adaptability to liquid level changes. Traditional fixed heat exchangers or heat exchange coils are often optimized based on static liquid level at the beginning of design, and fail to fully consider the impact of liquid level fluctuations on heat exchange efficiency. When the actual liquid level changes, the efficiency of the heat exchanger will drop significantly, resulting in reduced energy utilization and increased production costs. This defect is particularly prominent in scenarios where the liquid level changes frequently, becoming a key bottleneck in the industrial heat exchange process; secondly, equipment maintenance is difficult. The openness of the oil pool makes the heat exchanger susceptible to environmental factors such as corrosion and scaling, which will directly reduce the heat exchange efficiency. Traditional fixed heat exchangers or heat exchange coils have a fixed and complex structure, and maintenance and cleaning work is not only cumbersome but also costly. Utility Model Content
