Description
Technical field
The utility model relates to the safety aid in sulphuric acid process, is specifically related to the degassed acid seal device of a kind of acid discharge pipeline.
Background technology
In metallurgical off-gas acid-making production technique, in the vitriol oil of finally producing, be dissolved with a certain amount of SO
2gas, need remove acid gas at degassing tower, removes SO
2the vitriol oil of gas enters vitriol oil storage tank stores through acid discharge pipeline.At present, the most relieving haperacidity acid discharge pipeline employing 316L of enterprise materials, are connected with degassing tower bottom.Which has the following disadvantages: nubbin air in acid discharge pipeline, the SO that the water vapour in air and the vitriol oil volatilize
3in conjunction with forming acid mist, under the operational condition of degassing tower negative pressure, acid mist is mobile in acid discharge pipeline overhead (portion), and acid discharge pipeline erosion rate is accelerated, and when serious, can cause acid discharge pipe leakage, and vitriol oil ejection, exists potential safety hazard.
Utility model content
The purpose of this utility model is for the problems referred to above, a middle device is provided, is arranged between degassing tower and ACID, the acid mist in ACID and degassed acid are separated, reduce the corrosion speed of ACID, avoid ACID eating thrown and some potential safety hazards of causing.
For reaching above-mentioned technique effect, the utility model adopts following technical scheme: the degassed acid seal device of a kind of acid discharge pipeline, its structure comprises: upper cover, cylindrical shell, base, acid inlet tube and go out acid tube, upper cover, cylindrical shell and base are fixedly welded as the closed structure with cavity, port of acid inlet tube extends to described cavity bottom, the fixing welding of acid inlet tube outer wall and upper cover, another port of acid inlet tube is communicated with degassing tower bottom, a port that goes out acid tube extends in described cavity, go out the fixing welding in acid tube outer wall and cylindrical shell top, another port that goes out acid tube is communicated with ACID.
Preferably, the nearly upper cover end of described acid inlet tube arranges the first valve, described in go out acid tube nearly cylindrical shell end be provided with the second valve.
Preferably, described cylinder body bottom is also provided with blow-off pipe, and port of blow-off pipe extends in cylindrical shell, and another port is open to be arranged, and described blow-off pipe is provided with the 3rd valve.
Preferably, to be fixedly welded as the closed structure with cavity be cylindrical for described upper cover, cylindrical shell and base.
The beneficial effects of the utility model:
The utility model is simple in structure, practical, be convenient to make.Can effectively reduce acid discharge pipeline erosion rate, solve the problem of acid discharge pipeline corrosion leakage, safe and reliable, through degassing tower, remove SO
2the vitriol oil of gas, in degassed tower bottom acid mouth flows into the utility model, then enters vitriol oil storage tank through acid output pipeline.Although be negative pressure state in degassing tower, the air in acid discharge pipeline and acid mist are sealed by degassed acid seal device, can not rapid flow, substantially keep stationary state, thereby reduced acid discharge pipeline erosion rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, upper cover; 2, cylindrical shell; 3, base; 4, acid inlet tube; 5, go out acid tube; 6, blow-off pipe; 7, the first valve; 8, the second valve; 9, the 3rd valve; 10, ACID; 11, degassing tower.
Embodiment
As shown in Figure 1, the degassed acid seal device of a kind of acid discharge pipeline, comprise: upper cover 1, cylindrical shell 2, base 3, acid inlet tube 4, go out acid tube 5 and blow-off pipe 6, upper cover 1, cylindrical shell 2 and base 3 are fixedly welded as the cylindrical closed structure with cavity, 4 one ports of acid inlet tube extend to described cavity bottom, acid inlet tube 4 outer walls and the fixing welding of upper cover 1, acid inlet tube 4 another ports are communicated with degassing tower 11 bottoms, a port that goes out acid tube 5 extends in described cavity, go out the fixing welding in acid tube 5 outer walls and cylindrical shell 2 tops, another port that goes out acid tube 5 is communicated with ACID 10.
Through degassing tower, remove SO
2the vitriol oil of gas, in degassed tower bottom acid mouth flows into the utility model, then enters vitriol oil storage tank through acid output pipeline.Although be negative pressure state in degassing tower, the air in acid discharge pipeline and acid mist are sealed by degassed acid seal device, can not rapid flow, substantially keep stationary state, thereby reduced acid discharge pipeline erosion rate.
In order to make the utility model have better effect, nearly upper cover 1 end at acid inlet tube 4 arranges the first valve 7, at nearly cylindrical shell 2 ends that go out acid tube 5, be provided with the second valve 8, in cylindrical shell 2 bottoms, be also provided with blow-off pipe 6,6 one ports of blow-off pipe extend in cylindrical shell 2, another port is open to be arranged, and blow-off pipe 6 is provided with the 3rd valve 9.There have been stopping property that this three valves can the whole device of more effective control and the operability of break-make.After of a specified duration in use, in this practical bottom, can form the precipitation of a part of foreign material unavoidably, or in the time of need to carrying out maintenance by a small margin to the utility model, just acid inlet tube 4, the first valve 7 and the second valve 8 that go out on acid tube 5 are closed, on blow-off pipe 6, the 3rd valve 9 is opened, the acid of the degassed acid seal device of acid discharge pipeline is entered after trench, by blow-off pipe 6, carry out maintenance operation, if just blow-off pipe 6 and the 3rd valve 9 are set to demountable structure with cylindrical shell, can be easier by blow-off pipe 6 keep in repair, assorted clearly.
