Bubble curtain blowdown system and control method for bubble curtain blowdown system

Abstract

The invention relates to an air bubble curtain blowdown system and a control method, comprising an air bubble curtain generating tube with a vent hole, a high-pressure gas supply device for delivering high-pressure gas to the bubble curtain generating tube, and a gas velocity collection device at the vent hole The first collection module, the second collection module for collecting water flow velocity, the control module electrically connected with the first collection module and the second collection module, and the adjustment module for adjusting the high-pressure gas flow, the adjustment module and the control module electrical connection. During the operation process, the gas discharge velocity and water flow velocity at the exhaust hole are obtained in real time through the first acquisition module and the second acquisition module. The control module processes the collected data and controls the adjustment module to work. The system can realize real-time monitoring. The control of the system is more precise, and the gas discharge speed of the bubble curtain generation tube can be adjusted according to the water flow speed of different sizes, which is suitable for the sewage isolation operation under the environment of different sizes of ocean currents or river speeds.

Description

technical field [0001] The invention relates to the technical field of dredging sewage, in particular to an air bubble curtain sewage system and a control method for the air bubble curtain sewage system. Background technique [0002] The traditional dredging construction will cause the suspended matter deposited in the surrounding waters to spread in the water or even float on the water surface, causing great pollution to the environment. In response to national laws and regulations on ecological and environmental protection, it is imminent to improve the problem of serious dredging pollution. The bubble curtain pipeline can have a certain barrier effect on the diffusion of suspended solids around during the dredging operation. It not only allows ships and equipment to move freely on the bubble curtain, but also blocks suspended substances. However, the use of anti-fouling systems for environmental protection dredging in dredging projects is still in its infancy. There is a...
