For in the overall process of yellow phosphorus loading and unloading and transportation, prevent the spontaneous combustion of yellow phosphorus ingress of air, in tank body 8, be provided with liquid isolation layer 6 between medium and tank body 8 inner tops, and from air-filled pore 3 nitrogen injection, adopt the isolated mode of filling nitrogen that adds of liquid that yellow phosphorus and air are completely cut off, thereby guarantee the safe in utilization of yellow phosphorus railway transportation tank trucks; Air-filled pore 3 and deflation hole 4 all are provided with seal cover cap 10, seal cover cap 10 flexibly connects with air-filled pore 3 and deflation hole 4, tank body 8 tops are provided with washout hole 9, if washout hole 9 flushings hang over the residual phosphorus of tank inner surface, further guarantee the safety of yellow phosphorus loading and unloading and transportation, washout hole 9 can with above-mentioned deflation hole 4 shared holes; Manhole 1 below is provided with deflecting plate 15, avoids the corrosion to underframe 13 of the liquid that overflows from manhole; Tank body 8 is shallow " ∨ " shape structures that formed by the right angle frustum of a cone cylindrical shell assembly welding that links to each other with two ends end socket 20 respectively, adopts wedged bottom structure tank body, has improved the through unloading rate of yellow phosphorus medium; The device 12 of heating outward comprises and being provided with and the corresponding steam steam jacket of tank body 8 mechanism 18 that this steam steam jacket mechanism 18 is arranged on the toroidal frame 19, and toroidal frame 19 is connected with tank body 8, and steam steam jacket mechanism 18 is provided with steam inlet 17 and condensation-water drain 16; Liquid suction pipe 2 is removable liquid suction pipe, as the liquid suction pipe that cooperates of the liquid suction pipe that is threaded, clamping etc.; Breathing relief valve 5 is all steel breathing relief valve, and for preventing parts such as jar interior water vapour corrosion flap and spring, this valve adopts all steel material.
For in the overall process of yellow phosphorus loading and unloading and transportation, prevent the spontaneous combustion of yellow phosphorus ingress of air, in tank body 8, be provided with liquid isolation layer 6 between medium and tank body 8 inner tops, and from air-filled pore 3 nitrogen injection, adopt the isolated mode of filling nitrogen that adds of liquid that yellow phosphorus and air are completely cut off, thereby guarantee the safe in utilization of yellow phosphorus railway transportation tank trucks.Above-mentioned tank body 8 bottoms oblique tank body 8 bottom centre are provided with.Adopt wedged bottom structure tank body, improved the through unloading rate of yellow phosphorus medium, both sides, tank body 8 top also are provided with washout hole 9.If washout hole 9 flushings hang over the residual phosphorus of tank inner surface, further guarantee the safety of yellow phosphorus loading and unloading and transportation.Manhole 1 below is provided with deflecting plate 15.Avoid the corrosion of the liquid that overflows from manhole to underframe 13.Liquid suction pipe 2 is removable liquid suction pipe, as the liquid suction pipe that cooperates of the liquid suction pipe that is threaded, clamping etc.
Because yellow phosphorus requires solid-state airtight transportation in railway transport course, and yellow phosphorus is in entrucking after coagulation process, bulk density changes, cause a jar interior negative pressure, for guaranteeing tank body 8 internal and external pressure balances, be provided with breathing relief valve 5 at tank body 8 tops, for preventing parts such as jar interior water vapour corrosion flap and spring, this valve adopts all steel material.
For guaranteeing the safety of yellow phosphorus in loading and unloading and transportation, in tank body 8, be provided with liquid isolation layer 6 between medium and tank body 8 inside top, it can adopt water, or adopt other and yellow phosphorus immiscible, and proportion seals yellow phosphorus less than the liquid dielectric of yellow phosphorus, and charges into nitrogen from air-filled pore 4, guarantees that yellow phosphorus has liquid isolation layer 6 and nitrogen that yellow phosphorus and air are completely cut off in loading and unloading and transportation all the time, prevent the yellow phosphorus spontaneous combustion, thereby guarantee the safety of yellow phosphorus railway transportation tank trucks.When yellow phosphorus is unloaded, from the washout hole 9 at two ends, tank body 8 top, inject and water washes the residual phosphorus of tank body 8 inside faces, avoid residual phosphorus spontaneous combustion and to the corrosion of tank body 8 materials.
Because in air spontaneous combustion can take place under the yellow phosphorus normal temperature, therefore, yellow phosphorus security requirement in railway transportation, handling process is very high, require the liquid loading and unloading of yellow phosphorus, seal solid-state operation.When filling with substance, at first in tank body 8, inject liquid isolation layer 6, can select for use at this be easy to get, easily replenish, inexpensive aqueous medium, after heating water to 50～60 ℃, liquid phosphor is poured in the tank body 8 electrolyte levels to regulation, after yellow phosphorus solidifies fully, in tank body 8, add again cold water injection to regulation sealing height and from air-filled pore 4 nitrogen injection the air in the jar is replaced, sealing manhole cover, washout hole 9 and removable liquid suction pipe 2 blind flanges are transported safely.Because yellow phosphorus is in process of setting, volumetric shrinkage causes a jar interior negative pressure, for guaranteeing tank body 8 internal and external pressure balances, is provided with breathing relief valve 5 at tank body 8 tops, makes transportation safety.When unloading yellow phosphorus, outwards feed steam in the steam jacket 18 of heating apparatus 12, yellow phosphorus is heated to 50～60 ℃ dissolves yellow phosphorus, then yellow phosphorus is extracted out outside the jar, in this process, need in jar, to replenish nitrogen from air-filled pore 4, and in jar, inject and water hangs over the residual phosphorus of tank body 8 inside faces in order to cleaning from washout hole 9, to avoid residual phosphorus spontaneous combustion and to the corrosion of tank body 8 materials.The enforcement of such scheme guaranteed yellow phosphorus loading and unloading and the transportation in all the time by water and nitrogen-sealed, spontaneous combustion does not take place; During transportation, there are not the mutual collision and the leakage of barreled transportation, guarantee the tank car transportation safety; Tank body 8 is reusable again, greatly reduces the traffic cost expense; This car yellow phosphorus carrying capacity further improves, and makes that the transportation of yellow phosphorus tank car is more cheap.
