Description
Technical field
The utility model relates to a kind of liquid transporting apparatus, particularly relates to a kind of liquefied ammonia loading, unloading system.
Background technique
Liquefied ammonia is special product, and because ammonia is explosive, poisonous, liquefied ammonia loading, unloading system relates to the difficult problems such as device security, accurate measurement and environmental pollution.And the loading, unloading unit operation of liquefied ammonia is one of liquefied ammonia production, storage, sale enterprise basic operation unit.Current most of liquefied ammonia loading, unloading configuration and operation are comparatively simple and crude, have the hidden danger such as very big safety, environmental protection, and liquefied ammonia to fill and unload be all often unidirectional operation, duct arrangement is comparatively loaded down with trivial details, operation easier is larger.
Through retrieval, not yet occur the entrucking of liquid collecting ammonia at present and unload in the related content of integrated operating method and equipment in Chinese patent database.
Summary of the invention
The purpose of this utility model is to provide a kind of liquefied ammonia loading, unloading system, the entrucking of liquid collecting ammonia with unload in
Integrated operation, safer, energy-conservation with the loading, unloading work of guaranteeing liquefied ammonia, the hidden danger such as the safety while eliminating the liquefied ammonia loading, unloading, environmental protection.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of liquefied ammonia loading, unloading system mainly comprises liquid ammonia storage tank, compressor and liquefied ammonia tank vehicle, it is characterized in that described liquefied ammonia tank vehicle connects flowmeter by oil filling riser, oil filling riser also has bypass without flowmeter, liquefied ammonia tank vehicle also by the gas ammonia pipe through or connect the liquid ammonia storage tank top without compressor, described liquid ammonia storage tank has pipeline to connect liquefied ammonia tank vehicle and use the ammonia process units through pump or without pump, and liquid ammonia storage tank also is bonded into ammonia device through modulating valve, and described synthetic ammonia installation has pipeline to connect and use the ammonia process units through control valve.
Liquefied ammonia tank vehicle is train tank car or tank wagon.
The utility model is a set of novel production system of liquefied ammonia handling, and it is a set of diversification, safe, energy-conservation, and configuration is simple, easy to operate liquefied ammonia loading, unloading system.What loading, unloading train and loading, unloading automobile used is same set of handling oil filling riser and pipeline, has reduced the cost input.Liquefied ammonia flowmeter accurately and effectively is installed, guarantees accurate-metering and the safety of handling.In actual liquefied ammonia loading, unloading process, the design can change liquefied ammonia loading, unloading mode flexibly, and the mode of filling has following three kinds: (1) can be used storage tank self pressure reduction to fill according to the geographical position of liquid ammonia storage tank and handling point; (2) synthetic ammonia installation send ammonia pressure original just higher, can directly carry out liquefied ammonia and fill; (3) use independently Loading Pump to be filled.In filling process, the tank car gas ammonia returns to liquid ammonia storage tank, avoids effluxing befouling environment.The inventor sums up through long-term operating experience, and above several modes that fill can singlely be carried out, and also can use (needing valve to control coordinates) simultaneously.Safer for filling process, crucial pipeline valve adopts the automatic control adjustable valve gate control, and the entrucking flowmeter is set filling weight in advance, is integrated into the DCS control system, implements long-range dynamically control in real time, rapidly and efficiently.
The utlity model has following advantage: (1) liquefied ammonia loading, unloading system and synthetic ammonia installation, liquefied ammonia knock out drum, phosphorus ammonium production system integration one, can carry out online the operations such as liquefied ammonia conveying, supply, handling when liquefied ammonia is synthetic, the unit operation is independent of each other.(2) liquid collecting ammonia entrucking, the two-way function of unloading are integrated, and construction cost is low, and Safety performance is outstanding.(3) design system takes full advantage of existing equipment and geographical position, and the liquefied ammonia handling system is constructed to design, and flow process is simple and easy, arranges that simple operations is convenient.Adopt liquid ammonia storage tank and synthetic ammonia installation to supply online liquefied ammonia entrucking simultaneously, can significantly increase work efficiency.
A kind of liquefied ammonia loading, unloading system that the utility model provides, used proof by reality, reached predetermined purpose, is applicable to particularly liquefied ammonia loading, unloading field of liquid.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described:
embodiment:
A kind of liquefied ammonia dress of certain phosphate fertilizer factory of company, unloading system as shown in Figure 1, a kind of liquefied ammonia dress, unloading system mainly comprises liquid ammonia storage tank 6, compressor 5, liquefied ammonia tank vehicle 1, it is characterized in that described liquefied ammonia tank vehicle 1 connects flowmeter 3 by oil filling riser 2, oil filling riser 2 also has bypass without flowmeter 3, liquefied ammonia tank vehicle 1 also by gas ammonia pipe 4 through or connect liquid ammonia storage tank 6 tops without compressor 5, described liquid ammonia storage tank 6 has pipeline to connect liquefied ammonia tank vehicle 1 and with ammonia process units 10 through pump 7 or without pump 7, liquid ammonia storage tank 6 also is bonded into ammonia device 8 through modulating valve, described synthetic ammonia installation 8 has pipeline to connect with ammonia process units 10 through control valve 9.
The utility model can be selected pipeline and equipment as required neatly, unload unit operation as shown in Figure 2: liquefied ammonia tank vehicle 1 to be unloaded is in the contraposition of handling point, connect oil filling riser 2, start compressor 5 drawing liquid ammonia storage tank 6 top gas ammonias to tank car 1 pressurization to be unloaded, the interior liquefied ammonia of tank car 1 is pressed into to liquid ammonia storage tank 6 through oil filling riser 2 bypasses, completes and unload the liquefied ammonia operation.
