Abstract
Systems and related methods for purging air burst supply piping of accumulated water prior to delivering pulses of pressurized air to an interior of a screen intake through the air burst supply piping. The systems and methods can include a purge compressor delivering a purging air supply at a head pressure slightly above a head pressure of water in the air burst supply piping, wherein the head pressure of the water is equivalent to a depth at which the intake screen. The system and methods can also include a purge line arranged in a parallel orientation to an air burst supply line, wherein both the purge line and the air burst supply line are operably coupled to a pressurized air tank.
Claims20
A method for delivering pulses of pressurized air to a submerged screen intake, comprising:
- purging water accumulated within a length of air burst supply piping with purging air, the length of air burst supply piping connecting an onshore air system with a submerged screen intake;
- and
- delivering one or more pulses of pressurized air from the onshore air system to the submerged screen take after the length of air burst supply piping has been purged.
An air burst system for cleaning submerged screen intakes, comprising:
- an onshore air system;
- a submerged screen intake;
- and
- a length of air supply piping fluidly connecting the onshore air system and the submerged screen intake,
- wherein the onshore air system includes a burst line and a purge line fluidly connected to the submerged screen intake, said purge line introducing purge air to the length of air supply piping for purging water from the length of air supply piping and said burst line introducing one or more pulses of pressurized air to the length of air supply piping for cleaning debris from the submerged screen intake.
The air burst system of 16, wherein the onshore air system includes a control panel for receiving the pressure reading transmitted from the pressure sensor.
