Its core objective is to reduce energy waste and improve overall energy efficiency.

[0003] In industrial production processes, fluid transport systems commonly suffer from the following problems:

[0004] 1) When fluid flows through valves, elbows and other pipe fittings, due to the throttling effect and turbulence, a large amount of pressure energy is converted into useless heat energy and lost.

[0005] 2) Many industrial fluids (such as cooling water, compressed air, process media, etc.) still carry a large amount of low-temperature waste heat (usually below 60°C) after completing their main functions. This heat is difficult to utilize directly due to its low temperature and is directly discharged, resulting in energy waste. Therefore, we propose a fluid system energy comprehensive utilization device. Utility Model Content

At the same time, the fin array and the jacket layer 42 are combined to efficiently capture the waste heat of the fluid and reuse the heat energy by utilizing the external heat exchange circuit, so as to simultaneously solve the problems of pressure energy waste and low-temperature waste heat disposal.

Several turbulence protrusions 341 are installed on the stirring blades 34, and the turbulence protrusions 341 are distributed on both sides of the stirring blades 34.

[0036] The working principle of this utility model is as follows: By using a fluid system to flow fluid into fluid channel 1, the fluid passes through a rectifier grid to reduce turbulence and energy loss. At the same time, the stirring blades 34 convert the fluid pressure energy into mechanical energy to drive the transmission rod 31 to rotate. The transmission rod 31 uses a transmission mechanism to drive an external energy utilization device to achieve the recovery and utilization of fluid pressure energy. Meanwhile, the fin array and jacket layer 42 are combined to efficiently capture the fluid waste heat, and then the external heat exchange circuit is used to realize the reuse of heat energy to achieve the recovery and utilization of fluid waste heat. During this period, the turbulence protrusions 341 enhance fluid disturbance and expand the pressure energy capture range to avoid energy recovery dead zones caused by laminar flow. The corrugated grooves 411 increase the heat exchange area and enhance turbulent heat exchange, which can significantly improve the extraction efficiency of low-temperature waste heat, thereby facilitating the recovery and utilization of fluid pressure energy and waste heat. At the same time, it can solve the problems of insufficient energy recovery and complex equipment in traditional technologies.
