Abstract
The utility model discloses a sulphur trioxide storage tank capable of avoiding excessively high pressure in a tank body. The sulphur trioxide storage tank comprises the tank body, a liquid in-out port is arranged on the tank body, and an emptying port used for pressure relief is arranged on the tank body. By means of the arrangement of the emptying port used for pressure relief on the tank body, in the process of converting solid sulfur trioxide into liquid sulfur trioxide, even through a part of liquid sulfur trioxide is vaporized into the gaseous sulfur trioxide and the pressure in the tank body is increased, the pressure relief also can be achieved through the emptying port, the excessively high pressure in the tank body is avoided, and explosion caused by the excessively high pressure in the tank body can be avoided, and potential safety hazards are relatively small. A nitrogen inlet is arranged on the tank body in order to conveniently discharge the liquid sulfur trioxide in the tank body. A liquid pipe is arranged in the tank body so as to enable the liquid sulfur trioxide in the tank body to be fully pressed out, and at the same time, enable the liquid sulfur trioxide to be conveniently pressed out. The sulphur trioxide storage tank is suitable for being popularized and applied on the field of chemical equipment.
Description
Technical field
The utility model relates to the chemical plant field, especially a kind of sulphur trioxide storage tank.
Background technology
In Chemical Manufacture, the sulphur trioxide main application is as sulfonating agent, carries out the higher sulfonating reaction of difficulty.Sulphur trioxide is solid forms at normal temperatures, take very inconvenient, in use, usually its liquefaction need to be made it become behind the liquid in order to use, at present, it is to utilize drying room to the whole heating of sulphur trioxide storage tank or utilize hot water that the sulphur trioxide storage tank is carried out constant temperature and process that the sulphur trioxide of solid forms is changed into method that liquid sulphur trioxide takes usually, existing sulphur trioxide storage tank comprises tank body, be provided with liquid entrance and nitrogen inlet on the tank body, the use procedure of existing sulphur trioxide storage tank is as follows: first tank body is heated, make the sulphur trioxide of solid forms in the tank body change into liquid sulphur trioxide, then pass into nitrogen from nitrogen inlet, the sulphur trioxide of liquid state is extruded from liquid entrance, and then carry out sulfonating reaction, in heat process, liquid entrance and nitrogen inlet all seal, because there are three kinds of different crystal formations in sulphur trioxide under solid state, wherein the boiling point of the sulphur trioxide of some crystal formation is lower, in liquefaction process, the liquid sulphur trioxide of understanding some is vaporized into the sulphur trioxide of gaseous state, because existing tank body seals in heat process, any pressure release relief hole is not set yet, therefore, in heat process, pressure in the tank body can be increasing, produce malleation, cause tank body to be blasted easily, have larger potential safety hazard, in case and the sulphur trioxide storage tank blasts, and will cause very serious industrial accident.
The utility model content
The technical matters that the utility model solves provides a kind of too high sulphur trioxide storage tank of tank body internal pressure of avoiding.
The technical scheme that its technical matters that solves the utility model adopts is: this sulphur trioxide storage tank, comprise tank body, and be provided with liquid entrance on the tank body, be provided with the drain for pressure release on the described tank body.
Further be to be provided with nitrogen inlet on the described tank body.
Further be, be provided with the liquid pipe in the described tank body, liquid Guan Yiduan is communicated with liquid entrance, and the other end extends to tank base.
Further be that described tank base is provided with base.
Further be, be provided with protective case on the described tank body, described liquid entrance, drain, nitrogen inlet are positioned at protective case.
The beneficial effects of the utility model are: by be provided with the drain for pressure release at tank body, change in the process of liquid sulphur trioxide at the sulphur trioxide with solid forms, even the liquid sulphur trioxide of some is vaporized into the sulphur trioxide of gaseous state so that the pressure rising in the tank body, also can pass through the drain pressure release, avoid the hypertonia in the tank body, avoid tank body to blast because of hypertonia, potential safety hazard is less.
Description of drawings
Fig. 1 is the structural representation of the utility model sulphur trioxide storage tank;
Be labeled as among the figure: tank body 1, liquid entrance 2, drain 3, nitrogen inlet 4, liquid pipe 5, base 6, protective case 7.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, this sulphur trioxide storage tank comprises tank body 1, is provided with liquid entrance 2 on the tank body 1, is provided with the drain 3 for pressure release on the described tank body 1.The use procedure of this sulphur trioxide storage tank is as follows: first with tank body 1 heating, make the sulphur trioxide of tank body 1 interior solid forms change into liquid sulphur trioxide, then the sulphur trioxide of liquid state is discharged from liquid entrance 2, and then carry out sulfonating reaction, owing to the drain 3 that is provided with at tank body 1 for pressure release, change in the process of liquid sulphur trioxide at the sulphur trioxide with solid forms, even the liquid sulphur trioxide of some is vaporized into the sulphur trioxide of gaseous state so that the pressure rising in the tank body 1, also can pass through drain 3 pressure releases, avoid the hypertonia in the tank body 1, avoid tank body 1 to blast because of hypertonia, potential safety hazard is less.
In the above-described embodiment, for the ease of the liquid sulphur trioxide in the tank body 1 is discharged, be provided with nitrogen inlet 4 at tank body 1, nitrogen is led in the tank body 1 by nitrogen inlet 4, liquid sulphur trioxide in the tank body 1 is extruded, take very conveniently, and liquid sulphur trioxide is being extruded in the process of storage tank, also can by the pressure in the drain 3 adjustment tank bodies 1, avoid the hypertonia in the tank body 1.
For the liquid sulphur trioxide in the tank body 1 can all be forced out, also be convenient to simultaneously liquid sulphur trioxide is extruded, be provided with liquid pipe 5 in the described tank body 1, liquid pipe 5 one ends are communicated with liquid entrance 2, and the other end extends to tank body 1 bottom.
Further be, be convenient to place in order to make tank body 1, place tank body 1 and topple over, be provided with base 6 in tank body 1 bottom.
In addition; be provided with protective case 7 on the described tank body 1; described liquid entrance 2, drain 3, nitrogen inlet 4 are positioned at protective case 7, can avoid some foreign material to fall in the tank body 1 by protective case 7 is set, and also can protect simultaneously liquid entrance 2, drain 3, nitrogen inlet 4 injury-free.
