The invention discloses a central gas supply system of an LNG (Liquefied Natural Gas) vaporizing station. A regulating-metering odorization crowbar is internally provided with an LNG pressure regulating pipeline system, an anti-explosion electrical cabinet and an LNG odorization system. The central gas supply system is characterized in that the regulating-metering odorization crowbar is also internally provided with an electric heating tower, a horizontal gas pipe is arranged at the top of the electric heating tower, the LNG pressure regulating pipeline system is distributed on the horizontal gas pipe, and the anti-explosion electrical cabinet and the LNG odorization system are arranged below the LNG pressure regulating pipeline system in parallel. According to the central gas supply system, an integral skid-mounting structure can be effectively integrated, the floor space of a whole skid-mounted body can be reduced, the stability of the integral skid-mounting structure can be improved, and thus the integral skid-mounting structure can meet the requirements on long-distance transportation of a trailer. In addition, the floor space in site is reduced, and the equipment maintenance is facilitated.
Description
technical field [0001] The invention relates to an LNG gas supply system, in particular to a centralized gas supply system for an LNG vaporization station. Background technique [0002] In the LNG gas supply system, skid-mounted technology is widely used. An LNG gas supply system can be roughly divided into standard skids for unloading platforms, LNG low-temperature storage tank skids, storage tank pressurization control skids, pressure regulating metering and odorizing skids, among which LNG Cryogenic storage tank skids and storage tank pressurization control skids can be arranged in parallel in multiple groups. Manufacturers use channel steel or I-beam to weld some rectangular frames on the production site, and these rectangular frames are used as the base of these skids, and then weld and fix different equipment on the base according to needs to form corresponding skids. Finally, the skid is transported to the use site with a trailer for assembly. There are also manufac...
