Problems solved by technology
[0003] At present, in terms of utilization of abandoned mine water, most of them unilaterally use the thermal energy of mine water for heating, or unilaterally use the kinetic energy of high-level mine water to generate electricity. complex
[0004] Most of the existing tube bundle heat exchangers are stationary components, such as patent CN 110553519 B, which discloses a tube bundle heat exchanger. The heat exchange surface of the heat exchanger is smooth, the structure is compact, but the disturbance between the tubes is small, and the heat exchange efficiency is high. Relatively low, when used in mine water heat exchange, impurities are easy to block the pipe gap
In addition, the components of the heat exchanger are moved by consuming electric energy. For example, the patent CN209166182U discloses a rotatable tube-and-tube heat exchanger, which increases disturbance and improves heat exchange efficiency, but at the same time consumes more electric energy

The invention discloses a turbo type rotary heat exchanger linkage power generation device and an operation method. The turbo type rotary heat exchanger linkage power generation device comprises an upper static pipeline, an upper rotary pipeline, a heat exchange mechanism, a lower rotary pipeline and a lower static pipeline which are sequentially installed from top to bottom. The upper end and the lower end of the heat exchange mechanism are fixedly connected with an upper rotating pipeline and a lower rotating pipeline correspondingly, and the rotating pipelines are movably connected with the static pipeline. The upper rotating pipeline is in transmission connection with a middle shaft of the generator set through a transmission change gear; the internal space of the device is communicated to form a hollow waterway, and water flow can circulate in the device. Heat energy and kinetic energy of mine water can be converted at the same time for heating and power generation, and electric energy consumption can be avoided while the heat exchange efficiency of the heat exchanger can be improved.
Description
technical field [0001] The invention relates to the technical field of machinery, in particular to a turbine-type rotary heat exchanger linkage power generation device and an operating method. Background technique [0002] Mine water is a general term for natural leaching water in mines, beneficiation wastewater, overflow water from beneficiation waste slag dikes, and leaching water from slag accumulation yards. In the process of coal mining, all the water infiltrating into the underground mining space can be called mine water. The discharge of mine water is one of the pollution sources with industry characteristics in the coal industry. billions of cubic meters. [0003] At present, in terms of water utilization in abandoned mines, most of them unilaterally use the thermal energy of mine water for heating, or unilaterally use the kinetic energy of high-level mine water to generate electricity. complex. [0004] The existing tube-bundle heat exchangers are mostly static c...
