Abstract
A liquefied natural gas regasification coldness recovery and coldness storage device consists of an ice recovery device with coolant, an ice storage device with water and a plurality of heat exchange tubes inside and a circulating pump. The heat exchange tubes are connected with a natural gas storage can and a natural gas supply regulating box and are arranged in the coldness recovery device. The coldness recovery device is connected with the heat exchange tubes in the ice storage device through pipes and the circulating pump. The ice storage device is connected with a custom system through pipes and the circulating pump. Coldness released from regasification of LNG is carried by the coolant and is released in water in the coldness storage device, and ice water in the coldness storage device is fed to users through pipes. In this way, coldness generated from regasification of LNG is reutilized.
Description
Technical field
The utility model belongs to refrigerating field, relates in particular to the cold recovery ice storage unit of a kind of lng regas.
Background technology
Liquefied natural gas LNG is a kind of clean energy resource, in now being widely used in producing, living.According to natural gas when-163 spend, liquable characteristics under the normal pressure, pressure car or seagoing vessel transportation are adopted in the transportation of LNG at present more, the destination of LNG transportation is the LNG supply station that each department are built, in the natural gas supply station, LNG must once gasify again, flows to the user by pipeline then and uses.
The storage of LNG is very convenient, natural gas every cubic metre of weight in back can reach 424 kilograms because of liquefying, volume-diminished when having only gaseous state 1/625th, the method that common LNG gasifies again adopts empty bath formula or water-bath type, be that heat exchanger tube two connects natural gas storage tanks, natural gas supply regulating box respectively, heat exchanger tube is placed air or water, and cold discharges from air or water like this, and a large amount of cold air that produce when LNG gasifies have again wasted.Release cold 830KJ by per kilogram in the LNG gasification, every jar of LNG100 cubic meter meter, every jar of LNG gasifies and releases about 3,500 ten thousand KJ of cold, can be cold for 1 10000 squares office building idle call in 8 hours.Modernized large-scale LNG receiving station reserves are big, and its cold energy that gasifies and produce of effective recycling can produce huge economic benefit and social benefit.
Summary of the invention
The purpose of this utility model is exactly the cold energy that gasifies and produce for effective recycling LNG, and provides a kind of lng regas cold recovery ice storage unit.
The cold recovery ice storage unit of lng regas, by the cold retracting device that refrigerant is housed, be equipped with that accumulator water, that be built-in with some heat exchanger tubes is put and circulating pump is formed, the heat exchanger tube that connects natural gas storage tanks, natural gas supply regulating box is built in the cold retracting device, heat exchanger tube during cold retracting device is put by pipeline, circulating pump and accumulator joins, and accumulator is put by pipeline, circulating pump and custom system and joined.
Because the LNG liquefied natural gas enters cold retracting device by heat exchanger tube, the cold of release carries heat exchanger tube in putting by pipeline, accumulator by refrigerant, and cold is released in the water that accumulator puts, and the frozen water that accumulator is put uses for the user by pipeline.Like this, effective recycling the LNG cold energy that gasifies again and produce.
Description of drawings
Accompanying drawing the utility model system architecture schematic diagram.
The 1st, the LNG liquefied natural gas storage tanks, the 2nd, cold retracting device, the 3rd, accumulator is put, and the 4, the 5th, circulating pump, the 6th, the chilled water water knockout drum, the 7th, the chilled water water collector, the 8th, natural gas supply regulating box, 9--20 are valves.
Specific embodiment
The cold recovery ice storage unit of lng regas, by the cold retracting device 2 that non freezing solution is housed, be equipped with accumulator water, that be built-in with some heat exchanger tubes put 3 and circulating pump form, the heat exchanger tube that connects natural gas storage tanks, natural gas supply regulating box is built in the cold retracting device 2, heat exchanger tube during cold retracting device 2 is put by pipeline, circulating pump 4 and accumulator joins, and accumulator is put 3 and joined with user's cold supply system by pipeline, circulating pump 5.
Cold retracting device, accumulator are put and are box-shaped.As shown in the figure, cold supply system is made up of pipeline, chilled water water knockout drum 6, chilled water water collector 7 and user's air-conditioner, does not describe in detail at this.For better control system running, as shown in the figure, mounted valve 9-20 on pipeline.
Its working procedure is: earlier valve 13,14,15,16 and circulating pump 4 are opened, made the non freezing solution loop unimpeded; Open valve 17,18,19 and circulating pump 5 make the chilled water closed circuit unimpeded simultaneously; Last Open valve 9,10,11,12.
At this moment, the LNG liquefied natural gas enters cold retracting device 2 by heat exchanger tube, the cold that discharges is carried by non freezing solution and passes through pipeline, under the effect of circulating pump 4, enter accumulator and put heat exchanger tube in 3, and cold is released in accumulator puts in 3 the water, non freezing solution enters cold retracting device 2 again by pipeline, carries out next one circulation.
The water that accumulator is put in 3 constantly absorbs the mixture that cold becomes ice and water, and frozen water enters chilled water water knockout drum 6 by pipeline under the effect of circulating pump 5, use for the user; And return accumulator through chilled water water collector 7 and put 3, carry out next one circulation.
Enter natural gas after LNG gasifies again and regulate control cabinet, pass through valve 12 then to user's air feed.
Because LNG supply station capacity is big, the user uses for convenience, accumulator can be put 3 make movable, detachably, and seal, when the water in the tank storage device for cooling has been drawn sufficient cold and become the frozen water mixture, close related valve, this tank storage device for cooling is pulled down, transported to for user and use away from the LNG supply station; Simultaneously, refill an accumulator and put, thereby reach the dynamic provisioning of cold.
