Abstract
A liquid supply apparatus capable of removing micro-bubbles and particles is described, including a pipe, a laser provider and at least one micro-bubble/particle outlet. The laser provider provides a laser crossing the pipe, wherein the laser is provided in a manner such that a micro-bubble/particle blocking/repelling barrier is formed crossing the pipe blocking or repelling micro-bubbles, particles or both in the liquid in the pipe. The micro-bubble/particle outlet is disposed on the pipe between the barrier and the liquid inlet of the pipe, adjacent to the barrier for discharging micro-bubbles, particles or both.
Claims12
A liquid supply apparatus that can remove micro-bubbles and particles from a liquid, comprising:
- a pipe including a liquid inlet and a liquid outlet;
- a laser provider for providing a laser light layer crossing the pipe, the laser light layer is provided in a manner such that the laser light layer serves as a micro-bubble/particle blocking/repelling barrier for blocking or repelling micro-bubbles, particles or both from the liquid in the pipe to allow the micro-bubbles, particles or both to accumulate in front of or on the micro-bubble/particle blocking/repelling barrier;
- and
- at least one micro-bubble/particle outlet on the pipe between the micro-bubble/particle blocking/repelling barrier and the liquid inlet, adjacent to the micro-bubble/particle blocking/repelling barrier for discharging the micro-bubbles, particles or both.
