Description
Technical field
The present invention relates to liquefied natural gas receiving station and get seawater engineering field, particularly one adopts " wall type list pump single channel " liquefied natural gas receiving station seawater water intake facilities.
Background technology
Liquefied natural gas (hereinafter referred to as LNG) receiving station stores liquefied natural gas, then the device of transport gas outward.LNG gets the important component part that seawater engineering is LNG receiving station, is directly connected to the normal operation of gasification installation.How getting the seawater that water quality, water temperature and the water yield all meet gasifier requirement, is the whole core design point getting seawater engineering.The LNG receiving station be constructed and put into operation due to China is less, all monopolized by offshore company, and domestic petrochemical industry designing unit gets in LNG receiving station, draining field is in space state substantially from being designed into construction.
It is adopt " share forebay " mode that seawater engineering is got by traditional LNG receiving station, and it obtains seawater main flow and is: body of sea water-open diversion canal-dirt cleaner-share forebay-seawater pump room-aqueduct-gasification installation.The feature that this water intaking runner is arranged is: separate with pump house between filter screen, the middle water distribution forebay shared for multiple stage sea water pump.Seawater uniform distribution, by after shorter open diversion canal and dirt cleaner, by shared forebay, is given every Taiwan Straits water pump by seawater.This runner design requires to determine that the optimal size of shared forebay and angle of flare ensure the steady and even of current by physical experiments, need to determine corresponding wave absorption measure by model testing simultaneously, make the wave fluctuating range < 0.3m entered in forebay.The length and width optimal size that this runner is arranged and angle of flare need to be determined by runner physical experiments before construction drawing design.
Realizing in process of the present invention, inventor finds that prior art at least exists following problem:
Dalian LNG receiving station is located in the north, and winter temperature is lower, and equipment is exposed to outdoor, at any time by erosion that is freezing and salt fog, block without any before intake, and be arranged in again work effect district, if adopt " sharing forebay " to get seawater mode, there is following weak point:
1, physical experiments needs just can complete usually for 4 to 6 months, and then designing unit carries out working drawing detailed design according to the result of Logistics automatic system.Therefore, the minimum needs time of 1 year design cycle of whole seawater water intaking runner just can complete whole construction drawing design, design cycle is oversize, duration cannot ensure, more seriously a large breach without any safeguard procedures is left in the seawater water intaking region of planning, once there be high sea to attack, bring larger potential safety hazard by giving plant area of whole receiving station.
2, dig rock amount under water large, engineering cost is higher.
3, according to the conventional design of LNG receiving station, four fire pumps individually take four runners, between filter screen and arranged apart between pump, so not only strengthen the size of getting seawater pump room, floor space is large, and increase civilwork engineering quantity and investment, and limit by site condition of taking up an area, be unfavorable for centralized management and the operation monitoring of equipment.
4, equipment is exposed to outdoor, at any time by the erosion of the freezing and salt fog of north of china in winter, blocks before intake without any, is arranged in again work effect district simultaneously, affects the use of harbour and attractive in appearance.
