Description

Marine methanol fuel feeding and storage cabin group Technical Field The invention relates to the technical field of ships, in particular to a methanol fuel feeding and storage cabin group for a ship. Background Along with the transition from the shipping industry to low carbonization and environmental protection, the green methanol is used as a clean and environmental-friendly carbon-neutral fuel, and has become an important development direction of marine fuel by virtue of the remarkable advantages that the fuel can reduce about 99% of sulfur oxides (SOx) and 80% of nitrogen oxides and can reduce 25% of carbon dioxide at most, and is widely applied to feed and storage systems of various ships. The marine methanol fuel feeding and storage cabin group is used as core equipment for storing and conveying methanol fuel, and the operation stability and the safety of the marine methanol fuel feeding and storage cabin group directly determine the sailing safety and environment-friendly standard condition of a ship, wherein the pressure detection, the condensation and recovery of methanol volatile gas, the separation of methanol and water and the recycling and emission of medium are key technical links for guaranteeing the efficient, safe and environment-friendly operation of the cabin group, and are core pain points to be optimized and perfected in the current industry. In the pressure detection and control aspect, the traditional marine methanol storage cabin adopts a single-point pressure sensor to detect the pressure in the cabin, overpressure alarm or passive pressure relief can only be realized, the dynamic pressure change in the cabin caused by the volatilization characteristic of the methanol cannot be adapted, the volatility is strong under the normal temperature of the methanol, the temperature fluctuation and the liquid level change in the cabin can cause frequent and small fluctuation of the pressure in the ship navigation, the single-point detection is easy to generate data lag and detection blind areas, the pressure relief process directly discharges the methanol volatile gas to the atmosphere, the fuel waste is caused, the toxic and harmful gas is released, and the environmental protection emission requirement of the ship is not met. The liquid formed after the condensation of the recovered methanol volatile gas is the mixture of methanol and permeated water. The common electric centrifugal or membrane filtration type oil-water separator on the ship has limited efficiency on micro water separation and has the problems of easy blockage, frequent maintenance and dependence on electric power. The separation stability of the ship is reduced under the working conditions of long-term inclination and vibration of the ship. A passive separation structure is needed that is based entirely on physical principles such as gravity, capillary action, or centrifugal force, does not require a precision filter element, and can accommodate the dynamic environment of the vessel. The separated pure methanol is sent back to the storage cabin again, and the separated water is safely discharged out of the cabin, so that two independent pumping systems and complicated liquid level and purity electronic control logic are usually required at present. This not only increases the complexity of the system, but also creates a new point of failure. Once the control logic misjudges, water may be misinjected into the fuel tank or methanol may be misdischarged from the sea, causing serious accidents.
