Exhaust system for ballast pump of oil tanker

Abstract

The invention discloses an exhaust system for a ballast pump of an oil tanker and belongs to the field of marine equipment. The exhaust system comprises a gas circuit portion and a circuit portion. The gas circuit portion comprises a lower pressure gas source, a high pressure gas source, an electromagnetic valve, a gas control valve and a vacuum sprayer. The circuit portion comprises a control module and a liquid level detector. The control end of the electromagnetic valve is electrically connected to the control module; the liquid level detector is electrically connected to the control module for detecting the liquid level in a housing of the ballast pump; when the liquid level in the ballast pump is lower than a set height, the control module can control the electromagnetic valve to be connected; when the liquid level in the ballast pump is raised to the set height, the control module controls the electromagnetic valve to be disconnected, so that the ballast pump exhausts automatically; as the electromagnetic valve is adopted to control the lower pressure gas source which then controls the high pressure gas source, the electromagnetic valve can be arranged in a safe region where the oil gas concentration is relatively low to avoid the probability of generating electric sparks to ignite the oil gas when the electromagnetic valve acts, so that the exhaust system is safer.

Description

technical field [0001] The invention relates to the field of marine equipment, in particular to an exhaust system for an oil tanker ballast pump. Background technique [0002] Ballast pumps are used on ships to fill or expel water from ballast tanks to sink or float the hull. [0003] When injecting water into the ballast tank through the ballast pump, the ballast pump will not only inhale water, but also inhale a certain volume of gas, and the accumulation of gas in the ballast pump will cause serious cavitation of the ballast pump, thus affecting For the normal operation of the ballast pump, it is necessary to remove the gas accumulated in the shell of the ballast pump in time. [0004] Existing exhaust systems are mainly controlled by electronic control components, but in oil tankers, since a large amount of flammable and explosive oil gas is accumulated in the cabin, it is necessary to use as few electronic control components as possible in the exhaust system to avoid ...
