Abstract
The utility model discloses a liquid ammonia storage tank. The liquid ammonia storage tank comprises a tank body (1). A liquid phase feed inlet pipe (2) and a gas phase pipe (3) are connected at the top of the tank body (1). The gas phase pipe (3) is provided with a gas outlet valve (3a). A feed inlet valve (2a) is arranged at an end portion of the liquid phase feed inlet pipe. A liquid ammonia pump (2b) is further arranged on the liquid phase feed inlet pipe (2). A liquid ammonia outlet pipe (4) is communicated with the bottom of the tank body (1). A discharge outlet valve (4a) is arranged on the liquid ammonia outlet pipe (4). The tail end of the liquid ammonia outlet pipe (4) is connected on the liquid phase feed inlet pipe (2) between the liquid ammonia pump (2b) and the feed inlet valve (2a). A check valve (2c) is arranged on the liquid phase feed inlet pipe at an outlet of the liquid ammonia pump (2b). A change-over pipe (5) is connected on the liquid phase feed inlet pipe between the liquid ammonia pump (2b) and the check valve (2c). The liquid ammonia storage tank is simple and reasonable in structure, and capable of quickly transferring liquid ammonia in a storage tank when leakage or an emergency occur, and is greatly improved in safety performance.
Description
Technical field
The utility model relates to a kind of chemical material storage tank, relates in particular to a kind of liquid ammonia storage tank.
Background technique
Ammonia is widely used as a kind of important industrial chemicals; Be transportation and store convenient, usually with the ammonia of gaseous state by pressurization or the cooling liquid ammonia that obtains.Liquefied ammonia is widely used industrial, and has corrosivity, and easily volatilization, so its chemical accident incidence rate is quite high.Due to the corrosivity of liquefied ammonia self, the situation that basin often can occur revealing; Or other fortuitous events also can cause leakage.A large amount of liquefied ammonia leakage meetings bring serious infringement to environment and personnel; While in this type of accident treatment cycle is long, can cause huge economic loss.So when occur to reveal or other when unexpected, the liquefied ammonia of basin inside need to be moved away rapidly.Present most of storage tank mostly can't switch through again walks its inner liquefied ammonia, so Safety performance is low, easily causes the accident.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes prior art, and the anhydrous ammonia tank that a kind of Safety performance is high, can fast transfer when meeting accident walk its inner liquefied ammonia is provided.
For solving the problems of the technologies described above, concrete technological scheme of the present utility model is as follows:
A kind of anhydrous ammonia tank comprises tank body, and a liquid phase feeding pipe and gas phase pipe are connected to described tank body top; Described gas phase pipe is provided with gas outlet valve; Described liquid phase feeding tube end is provided with feeding valve, also is provided with an ammonia pump on described liquid phase feeding pipe;
It is characterized in that: be communicated with a liquefied ammonia in described tank base and go out pipe, described liquefied ammonia goes out pipe and is provided with discharge valve; Described liquefied ammonia goes out to manage end and is connected on described liquid phase feeding pipe, and link position is between described ammonia pump and feeding valve;
Also be provided with a stop valve on the liquid phase feeding pipe in described ammonia pump outlet port; One transfer tube is connected on liquid phase feeding pipe between described ammonia pump and stop valve, and described transfer tube 5 is provided with a valve 5a.
The utility model has the advantage of: when occur revealing or in case of emergency, can be rapidly the liquefied ammonia of storage tank inside be transferred in other storage instruments rapidly, have greatly improved the Safety performance of basin, can effectively avoid the generation of accident.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
In conjunction with shown in Figure 1, the utility model comprises that tank body 1, one liquid phase feeding pipe 2 and gas phase pipe 3 are connected to described tank body top; Described gas phase pipe 3 is provided with gas outlet valve 3a; Described liquid phase feeding tube end is provided with feeding valve 2a, also is provided with an ammonia pump 2b on described liquid phase feeding pipe 2; Go out pipe 4 at described tank body 1 bottom connection one liquefied ammonia, described liquefied ammonia goes out pipe 4 and is provided with discharge valve 4a; Described liquefied ammonia goes out pipe 4 ends and is connected on described liquid phase feeding pipe 2, and link position is between described ammonia pump 2b and feeding valve 2a; Also be provided with a stop valve 2c on the liquid phase feeding pipe in described ammonia pump 2b outlet port; One transfer tube 5 is connected on liquid phase feeding pipe between described ammonia pump 2b and stop valve 2c; Described transfer tube 5 is provided with valve 5a.
Specific works flow process of the present utility model is as follows: under normal use condition, discharge valve 4a and valve 5a keep normally off, and stop valve 2c keeps normally open; When storage liquefied ammonia in tank body 1, open feeding valve 2a, just can realize its charging under the effect of ammonia pump 2b; The valve 3a that opens on the gas phase pipe can be transported to ammonia in follow-up course of reaction.When tank body 1 occurs to leak or runs into other urgencies, close stop valve 2c and feeding valve 2a, open discharge valve 4a and valve 5a; The liquefied ammonia of tank body 1 inside through the effect of oil hydraulic pump 2b by rapidly through transfer tube 5 outputs, can be transferred in the specific store instrument such as the special-purpose tank car of liquefied ammonia.
The utility model is simple and reasonable, when occur revealing or in case of emergency, can be rapidly the liquefied ammonia of storage tank inside be transferred in other storage instruments rapidly, has greatly improved the Safety performance of basin, can effectively avoid the generation of accident.
