Modular anti-rotation drilling systems and methods actuated by fluid pressure
| DWPI Title: Falling particle solar receiver system, has solar receiver including inlet and outlet, particle flow control devices arranged at inlet of solar receiver to control temperature of set of particles, and hopper connected to control devices |
| Abstract: A modular anti-rotation, centering and notching device for preventing off-axis movement of a drillstring with respect to the central axis of a drilling tool in a borehole and for producing a notch in a borehole surface. The device includes an upper fixture portion and a lower fixture portion in axial alignment. The upper fixture portion and the lower fixture portion are connected by yoke assemblies. Each yoke assembly is connected to the fixture portion and fixture portion at one end, and forming an articulated joint of the upper yoke assembly and the lower yoke assembly at a distal end opposite the first end. A roller is connected at each joint, connecting the upper and lower yoke assemblies. The rollers or cutters engage vertically with a borehole surface when fluid pressure is applied to the upper fixture portion. |
| Use: Falling particle solar receiver system. |
| Advantage: The system controls particle outlet temperature automatically by adjusting a particle mass flow rate through the receiver using a closed-loop control system. |
| Novelty: The system (100) has a solar receiver (102) including an inlet and an outlet. Multiple particle flow control devices (120) are arranged at the inlet of the solar receiver to control temperature of a set of particles. A hopper is connected to the particle flow control devices. The hopper discharges the set of particles. The particle flow control devices comprise a flow control element. The flow control element comprises a slide gate device. A storage bin (104) is provided with the inlet and the outlet, and connected to the outlet of the solar receiver. A heat exchanger (106) includes an inlet and an outlet, and connected to the storage bin. |
