Adopt the beneficial effect of above technical scheme to be: sulfuric acid loading and unloading system of the present utility model, in the situation that not affecting normal handling, liquid seal can fully absorbs the sulphur trioxide overflowing and has greatly reduced overflowing of sulphur trioxide in system, and what make oleum draws off environment safer more environmental protection.The utilization ratio that has improved oleum raw material, the sulphur trioxide overflowing is recycled after being converted into acid solution.On oleum storage tank and absorption liquid storage tank, be all provided with monitoring device can Real-Time Monitoring the every terms of information of storage pot liquid, facilitate staff's real-time monitored to improve the security of whole system.
Accompanying drawing explanation
Mark in the each accompanying drawing of this specification sheets expressed content and figure is made to brief description below:
Fig. 1 is structural representation of the present utility model;
Mark in above-mentioned figure is: 1, oleum storage tank; 2, absorption liquid storage tank; 3, liquid seal can; 4, charge pump; 5, absorption liquid drain tube; 6, unload acid mouthful; 7, exhausting pipeline; 8, vapor pipe; 9, blow-down pipe; 10, upflow tube; 11, liquid discharge pipe; 12, spout; 13, pressure monitoring device; 14, level monitoring device; 15, device for detecting temperature; 16, overflow port; 17, unload acid tube; 18, valve.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail as effect and the principle of work etc. of the mutual alignment between the shape of related each member, structure, each several part and annexation, each several part: the loading and unloading system of this oleum comprises oleum storage tank 1, sulfuric acid storage tank 2, liquid seal can 3, unloads acid tube 17 and vapor pipe 8.As shown in Figure 1, oleum is stored in oleum storage tank 1, in the time that unloading oleum, needs dock with dress oleum tank car bottom discharge flange unloading acid mouth 6, exhausting pipeline 7 docks with tank car top emptying valve, open valve 18 simultaneously, unload the valve of acid mouthfuls 6 and exhausting pipeline 7, sulfur trioxide gas in oleum storage tank 1 passes into tank car by vapor pipe 8, and oleum passes into tank car by unloading acid tube 17.After unloading acid, close the valve unloading on acid mouthfuls 6 and exhausting pipeline 7, then disconnect and unloading being connected of acid mouthfuls 6 and exhausting pipeline 7 and tank car.Whole unload in sour process can be adjusted and unload sour speed and unload acid amount by being arranged on pressure monitoring device 13, level monitoring device 14 and device for detecting temperature 15 on oleum storage tank 1 in safety range.Exhausting pipeline 7 is provided with valve, valve opening be connected with tank car and allow unnecessary gas enter tank car while unloading acid.Valve closes when normal storage state on exhausting pipeline 7, the sulphur trioxide in oleum storage tank 1 enters liquid seal can 3 by vapor pipe 8 and is absorbed.The whole system in sour process of unloading, in air-tight state, does not have sulfur trioxide gas and overflows.On oleum storage tank 1, being also provided with charge pump 4 sends into oleum between reacting vehicle.
Normal storage state, valve 18 is opened, and oleum storage tank 1 is connected with liquid seal can 3, and oleum storage tank 1 is whole airtight.Described liquid seal can 3 is divided into two-layer up and down, between levels, connects by blow-down pipe 9, has certain pressure in oleum storage tank 1, and the size of pressure is determined by the degree of depth that in liquid seal can 3, blow-down pipe 9 inserts in absorption liquid.If may cause absorption liquid suck-back in liquid seal can 3 when the pressure in oleum storage tank 1 is lower simultaneously, because so a small amount of absorption liquid that liquid seal can 3 is upper and lower double-layer structure suck-back can only be back in the upper strata cavity of liquid seal can by blow-down pipe 9, because the liquid that exists of cavity 3 can not enter oleum storage tank 1 by suck-back.A small amount of sulphur trioxide is absorbed by the absorption liquid in liquid seal can 3, and whole system does not have sulphur trioxide and overflows.Due to the material properties of oleum itself, the situation that in oleum storage tank 1, pressure is too large or too little there will not be substantially.
When liquid seal can 3 changes liquid operation, valve-off 18, open the valve on liquid discharge pipe 11, absorption liquid in liquid seal can 3 is put into sulfuric acid storage tank 2, close the valve on liquid discharge pipe 11 after discharging absorption liquid, open spout 12, inject absorption liquid, control by overflow port 16 height that absorbs liquid level, absorption liquid unnecessary after reservoir quantity exceedes overflow port 16 can flow in absorption liquid storage tank 2 by upflow tube 10, and described liquid discharge pipe 11 is connected on described upflow tube 10.After fluid injection, close spout 12, open valve 18.Absorption liquid is stored in absorption liquid storage tank 2, emits by absorption liquid drain tube 5 when exceeding after certain liquid measure, carries out follow-up recycling or environmental protection treatment.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
