Technical Field

[0001] The invention relates to the technical field of evaporators, in particular to an evaporator energy-saving heat exchange component for recycling waste mineral oil. Background Art

[0002] Waste mineral oil is extracted and refined from petroleum, coal, and oil shale. During the mining, processing, and use process, the original physical and chemical properties have been changed due to external factors, and the mineral oil can no longer be used. If the waste mineral oil is not properly handled, once it enters the external environment in large quantities, it will cause serious environmental pollution, destroy the normal living environment of organisms, and have the physical effect of causing biological dysfunction. When the soil voids are large, petroleum wastewater can also penetrate into the soil layer and pollute shallow groundwater. The existing waste mineral oil treatment methods mostly use distillation to distill the waste mineral oil level by level, and then centrally treat the remaining solid waste residue.

The energy-saving heat exchange component of an evaporator for recycling waste mineral oil according to claim 8, characterized in that: After the supporting block (32) moves along with the adjusting rod (33), the surface of the supporting block (32) is supported on the surface of the force applying block (26), so that the force applying block (26) moves on the surface of the fixing rod (20); since the first clamping groove (19) on the surface of the fin (35) is clamped on the surface of the fixing rod (20), the force applying block (26) on the surface of the fixing rod (20) is supported on the surface of the first clamping groove (19) after moving, so that the fin (35) is stabilized on the surface of the fixing rod (20).

10. The energy-saving heat exchange component of an evaporator for recycling waste mineral oil according to claim 9, characterized in that: A spring (31) is provided on the surface of the adjustment rod (33), one end of the spring (31) is connected to the inner wall of the transverse groove (34), and the other end is connected to the surface of the supporting block (32). The spring (31) exerts a pulling force on the supporting block (32), so that the force-bearing rod (29) at the end of the adjustment rod (33) is close to the surface of the second moving rod (16). When the adjustment rod (33) moves, the spring (31) is stretched.
