Description
Technical field
The utility model is related to chemical field, in particular it relates to a kind of unloading system of liquefied ammonia.
Background technology
Liquefied ammonia, also known as anhydrous ammonia, are a kind of colourless liquids.Ammonia is widely used in chemical industry neck as important industrial chemicals
Domain, in order to transport and store conveniently, generally obtains liquid ammonia by pressurization or cooling by gaseous ammonia, then passes through tank car
It is discharged in holding vessel and is stored, it is necessary to be taken again when being used in the factory for transporting needs.Liquefied ammonia is industrially widely used,
With corrosivity and volatile, so its chemical accident incidence is at a relatively high.
In the prior art, liquefied ammonia is discharged to use in holding vessel and raises tank car or drop holding vessel by factory from tank car
Mode that is low, being flowed to automatically in holding vessel using the liquefied ammonia in height official post tank car.When unloading, by between holding vessel and tank car
Gas pipeline connection so that both pressure reaches balance, then utilizes difference in height between the two so that the liquid in tank car
Ammonia is flowed in holding vessel automatically from the fluid pipeline connected between the two.Because the caliber of fluid pipeline is typically small, and
Both difference in height also will not be very big, causes to unload vehicle speed slower.
Utility model content
The purpose of this utility model is to provide a kind of unloading system of liquefied ammonia, and the unloading system can be realized to be added to liquefied ammonia
Speed is unloaded, and whole unloading system is safe and reliable, reduces A leak of liquefied ammonia, reduces environmental pollution.
To achieve these goals, the utility model provides a kind of unloading system of liquefied ammonia, including liquefied ammonia holding vessel, vehicle-mounted
Groove tank, the feed tube of liquefied ammonia holding vessel is connected with the liquid outlet of groove tank, and the top of liquefied ammonia holding vessel sets exhaust outlet, exhaust outlet
Upper setting blast pipe, described blast pipe is connected with the gas pipeline set in vehicle-mounted groove tank, and air chamber is set on blast pipe,
Turbine is set in air chamber, and described turbine is driven by motor, sets and is set out below condenser system, air chamber outside air chamber
Liquid pipe, drain pipe is connected with feed tube.
Described air chamber bottom sets inclined-plane, and drain pipe is arranged on inclined-plane bottom, and described condenser system is board-like cold
Solidifying system.
Described inclined-plane sets two, and the bottom on two inclined-planes is close to each other, and drain pipe is arranged on two contact of incline plane
Part.
Valve is set on described blast pipe, and described valve is arranged on blast pipe close to one end of gas pipeline.
Flowmeter is set on feed tube.
Compared with prior art, it is made the utility model by the use of the ammonia of itself in liquefied ammonia holding vessel as pressure source
Process of unloading more efficiency, and remaining ammonia is cooled into after liquefied ammonia and returns in liquefied ammonia holding vessel, is wasted without any, also not
There is the pollution of environment.
Brief description of the drawings
Fig. 1 is the schematic diagram of the unloading system of the liquefied ammonia of embodiment of the present utility model.
Wherein the vehicle-mounted groove tank of 1- liquefied ammonia holding vessel, 2-, 3- feed tubes, 4- air chambers, 5- turbines, 6- blast pipes, 7- are board-like cold
Solidifying system, 8- inclined-planes, 9- flowmeters, 10- drain pipes.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
The utility model relate to a kind of unloading system of liquefied ammonia, for the liquefied ammonia of outsourcing to be drawn off out of groove tank car, also
Poured into available for by finished product liquefied ammonia in groove tank car, it includes the vehicle-mounted groove tank 2 of liquefied ammonia holding vessel 1 and groove tank car, liquefied ammonia holding vessel 1
Feed tube 3 be connected with the liquid outlet of vehicle-mounted groove tank 2, the gas pipeline of the exhaust outlet of liquefied ammonia holding vessel 1 and vehicle-mounted groove tank leads to
Cross a blast pipe 6 to be connected, certain difference in height is added by such connection, unloading for liquefied ammonia just can be realized.
For unloading more efficiently, the utility model sets an air chamber 4 on described blast pipe, specifically,
Blast pipe 6 is divided into two sections by air chamber 4, the two ends of air chamber 4 with the fixed seal connection of blast pipe 6, it is ensured that do not have ammonia from
Joint leaks, the volume about 3-5L of air chamber 4 sets a turbine 5 inside it, and turbine 5 is carried out by drive system to it
Driving, the rotation of turbine 5 drives the ammonia of evaporation in blast pipe 6 to accelerate, and then gives vehicle-mounted groove tank 2 certain pressure,
Accelerate the conveying of liquefied ammonia；Simultaneously because the ammonia in liquefied ammonia holding vessel is extracted, it is negative pressure in liquefied ammonia holding vessel 1, further
The conveying to liquefied ammonia accelerate, in order to avoid liquefied ammonia holding vessel is reversely evacuated out of blast pipe, set single in blast pipe
To valve, make liquefied ammonia conveying more stable.
After liquefied ammonia conveying is finished, the remaining more evaporation ammonia of meeting in air chamber and blast pipe, this portion gas is general
For the approach that is recycled be that the concentration of ammoniacal liquor for obtain after spray-absorption, spray using demineralized water is irregular not mostly
Together, secondary operation is also carried out for selling, is very inconvenience.The utility model is provided with condenser system in the outside of air chamber, will
Ammonia in air chamber is condensed, and makes it be changed into liquefied ammonia again, then enters this part liquefied ammonia loopback in liquefied ammonia holding vessel.Realize
The circulation of liquefied ammonia.Specifically, described condenser system is board-like condenser system 7, and its film-cooled heat is big, condensation effect also compared with
To be obvious, blast pipe 6 sets valve at the gas pipeline of vehicle-mounted groove tank, also can be in the junction of blast pipe and vehicle-mounted pipeline
Valve is set, blast pipe and vehicle-mounted pipeline are connected by valve, when air chamber is condensed, negative pressure is kept in air chamber, ammonia can
To be continuously drawn into air chamber, drain pipe 10 is set in air chamber bottom, drain pipe is connected on the feed tube of liquefied ammonia holding vessel, gone out
It is same in liquid pipe that valve is set, to ensure to allow air chamber to completely cut off with feed tube in pumping process.
The lower section of spatial portion in air chamber, sets inclined-plane 8, and inclined-plane 8 can set one, two is also can be set, on inclined-plane
Minimum point set drain pipe, can so ensure that all liquefied ammonia being condensed are collected and be back in liquefied ammonia holding vessel.
Whether have liquefied ammonia flow through, and then judge liquefied ammonia if being also set up on feed tube in flowmeter 9, flowmeter monitoring feed tube
Whether completed loading.
The utility model can still be condensed ammonia formation liquefied ammonia by air chamber, realize liquid when being unloaded without liquefied ammonia
The absorption of ammonia.
