Fuel transmission and distribution sealing module safety delivery system for dual-fuel powered fishing vessels

Abstract

The invention discloses a fuel transmission-distribution sealing module safe conveying system of a dual fuel power fishing vessel. The system comprises an adsorption gas recycle sealing unit, a control unit and a gas storage and supply sealing unit, a gas interlock sealing unit, a gas reduced pressure sealing unit and a gas jet sealing unit which are connected by a hollow ventilated gas conveying pipe in sequence and are sealed by a bearing sealing box respectively, wherein the residual air discharge end of the gas interlock sealing unit is connected with the gas suction end of the adsorption gas recycle sealing unit through gas circuit; the output end of the gas jet sealing unit is connected with an engine through the hollow ventilated gas conveying pipe; the signal input end of the control unit is electrically connected with the signal output ends of the gas storage and supply sealing unit, the gas interlock sealing unit, the gas reduced pressure sealing unit, the gas jet sealing unit and the engine; the signal output end of the control unit is electrically connected with the signal input ends of the gas interlock sealing unit, the gas reduced pressure sealing unit and the gas jet sealing unit. The fuel transmission-distribution sealing module safe conveying system is intuitive, concise and clear and definite, and the intrinsic safety type is realized conveniently.

Description

technical field [0001] The invention relates to a gas fuel (LNG, CNG, ANG, LPG, H 2 ) and diesel dual-fuel powered fishing vessels. In particular, it relates to a fuel delivery and distribution sealing module safety delivery system for a dual-fuel powered fishing vessel. Background technique [0002] Shipping industry and fishing industry are important components of marine economy, but increasingly depleted oil and serious pollution have become bottlenecks restricting the development of transportation industry and fishing industry. With the strict regulations of the International Maritime Organization (IMO), the emission control waters of ECA Europe will reduce the sulfide emission limit from the current 1% to 0.1% from 2015; The limit will drop from 4.5% now to 0.5%. Therefore, low-sulfur and low-carbon alternative fuels and technologies using such fuels must be developed as soon as possible to meet the international time-limited and emission-limited standards. LNG, whi...

Problems solved by technology

Therefore, under the constraints of the "intrinsically safe" concept for LNG diesel / dual-fuel powered ships, the equipment used for gas technology transformation not only occupies a large area, but all parts in a cabin that involve gas installations must be protected from explosion-proof From a different perspective, the cost is naturally high, which has greatly hindered the promotion of gas technology achievements
