Automatic air-purging type oil spill prevention device and control method thereof

Abstract

The invention discloses an automatic air-driving type oil spill prevention device and a control method thereof, which comprise a vent (1), an oil-gas separation vent device (3), a quick interface (4), a refueling pipe (22) and an oil inlet pipe (26 ); one end of the refueling pipe is connected to the refueling hose through a quick interface, and the other end of the refueling pipe is connected to the oil tank through the oil inlet pipe; the oil-gas separation and ventilation device is connected to the oil inlet pipe, and a centrifugal impeller (7) is installed in the oil-gas separation and ventilation device. The outlet is installed on the top of the oil-gas separation and ventilation device through the connecting pipe (28), so that the air is discharged upward through the centrifugal impeller through the ventilation port, and the diesel oil flows back into the oil tank through the centrifugal impeller through the inner wall of the oil-gas separation and ventilation device. The invention can effectively avoid oil leakage pollution accidents caused by jumping pipes, realize the purposes of quick disassembly and assembly and real-time monitoring of the whole process, and effectively improve the automatic protection level of the device.

Description

technical field [0001] The invention relates to an automatic gas-purging device and method for a piping system and an oil tank during the refueling process of a tugboat, in particular to an automatic gas-purging type oil spill prevention device and a control method thereof. Background technique [0002] Port operation tugboats mainly serve the assisting tasks (push, tow, etc.) of large ships at each wharf, and also take into account piloting and some emergency rescue operations under special circumstances. The tugboat has the characteristics of small hull and strong horsepower . [0003] From the perspective of ship equipment functions: the main engine on the ship is the device that provides the main power for the ship, and in the tugboats of the prior art, it is mainly two high-power marine four-stroke diesel engines; and the generator is to provide the ship with continuous power (including Power supply and lighting power supply) are mainly powered by 2 small diesel engine...

AI Technical Summary

Problems solved by technology

With this simple structure, when a large amount of oil and gas cannot be discharged in time, the refueling hose of the oil truck will be separated (jumped) from the oil filling port of the tugboat. If it cannot be detected and stopped in time, it will cause more serious "running". oil accident

[0013] To sum up, oil spill is not only a loss of energy, but also an environmental pollution accident
