Abstract

The invention discloses a sea water taking instrument for a liquefied natural gas receiving station, and belongs to the field of sea water taking engineering of liquefied natural gas receiving stations. The sea water taking instrument comprises a quay wall type member, a single-pump and single-channel system and a draining blind drain, wherein the quay wall type member is built below the embankment of a working ship wharf; the single-pump and single-channel system is arranged in a water taking pump room; the draining blind drain is built between the quay wall type member and the water taking pump room; the quay wall type member is communicated with the draining blind drain; the draining blind drain is communicated with the single-pump and single-channel system. In the quay wall type member, a water taking port and the working ship wharf are combined into a whole, so that the water front of the wharf is utilized fully; the water taking port is connected with a flow channel of the water taking pump room through the draining water blind drain, so that the influence of open sea waves on the water level fluctuation of the water pump flow channel is eliminated remarkably; a sea water fire pump is arranged at the front end of a sea water taking pump, and share one water taking flow channel with the sea water taking pump, so that the floor area is reduced, and the civil engineering quantity and investment are lowered.

Description

technical field [0001] The invention relates to the field of seawater intake engineering of a liquefied natural gas receiving station, in particular to a seawater intake facility of a liquefied natural gas receiving station using "shore-wall type single pump and single channel". Background technique [0002] Liquefied natural gas (hereinafter referred to as LNG) receiving station is a device for storing liquefied natural gas and then transporting natural gas outside. The LNG seawater intake project is an important part of the LNG receiving station, which is directly related to the normal operation of the gasification device. How to obtain seawater with water quality, water temperature and water volume that meet the requirements of the vaporizer is the core design point of the entire seawater intake project. Since there are few LNG receiving stations built and put into operation in my country, they are monopolized by foreign companies from design to construction, while domes...
