Description

Technical Field

[0001] The invention relates to the technical field of warehouses, and in particular to a device for deep processing of tail gas from a boiling furnace. Background Art

[0002] In the prior art, the use of fluidized bed furnaces is very extensive, including the refining of pyrite, in which the reaction occurring in the fluidized bed furnace is 4FeS2+11O2=8SO2+2Fe2O 3。 The gas entering the boiling furnace is air, the main components of air are oxygen and nitrogen. Nitrogen does not participate in the reaction, so there is nitrogen that does not participate in the reaction in the exhaust gas. The catalytic oxidation of SO2 in the contact chamber requires oxygen, so oxygen is discharged. In addition, a small amount of powdered solid mixture will be discharged with the airflow.

[0003] In summary, we can know that the exhaust gas inside the boiling furnace at this time is mainly SO2, O2, N2, and mineral dust. Among these exhaust gases, SO2 is not the main component of the air. The random emission of SO2 may cause the sulfur dioxide emitted into the atmosphere to form acid rain, acidify the water quality, cause changes in the aquatic ecosystem, kill plankton, and affect fish reproduction. The random emission of mineral dust into the air may cause smog and affect people's respiratory tract.

[0004] The current treatment method is to put the exhaust gas into a sealed tank. At this time, sodium carbonate and sulfur dioxide come into contact with each other to generate sulfuric acid precipitate, thereby achieving the purpose of treating sulfur dioxide. However, when the device is currently reacting, the sodium carbonate and sulfur dioxide in the tank react to form a precipitate. As the precipitate accumulates, the liquid level inside the tank rises, causing the reaction liquid to leak from the outlet pipe, thereby causing unnecessary waste of treatment liquid.

[0033] See also Figure 1-8 In this embodiment, support legs 5 are fixedly mounted on the lower surface of the housing 1.

[0034] It should be noted that the present invention is a deep treatment device for boiling furnace exhaust gas, and each component is a universal standard component or a component known to technical personnel in this field. Its structure and principle can be known to technical personnel through technical manuals or through conventional experimental methods.

[0035] Working principle: When the device needs to be used, the treatment liquid is injected into the treatment box 11 through the treatment liquid delivery pipe 2, and the exhaust gas is put into the treatment box 11 through the air inlet pipe 4. After the exhaust gas passes through the treatment liquid, it enters the drying box 7 through the gas delivery pipe, and finally the gas is dried by the desiccant 37 inside the drying box 7, and then the gas is discharged.

[0036] With the long-term use of tail gas treatment, the treatment liquid inside the device forms a precipitate with sulfur dioxide. As the precipitate accumulates, the liquid level rises, which will drive the large float 14 to move upward, and during the movement, the first slider 15 is mobilized by the bracket 13 to move upward along the slide 16, and the second slider 18 is mobilized by the synchronization rod 17 to start moving upward. At this time, the position of the first connecting rod 19 starts to change, and the positioning slider 20 at the end is pulled to move along the positioning slide 31. As the positioning slider 20 moves, the block 33 is finally matched with the groove 29. At this time, the movement of the positioning slider 20 will drive the second connecting rod 21 to move, and finally the limit rod 32 is moved downward, so that the conical sealing plug 28 falls, thereby facilitating the internal precipitation to be discharged through the discharge port 27. At this time, the force on the surface of the positioning slider 20 is, and the extrusion spring 30 is pressed toward The right elastic force, the left pulling force of the first connecting rod 19, and the left pushing force of the second connecting rod 21, at this time the positioning slider 20 maintains balance. As the liquid is discharged, the large float 14 moves downward, and the left pulling force of the first connecting rod 19 becomes smaller. However, at this time, the block 33 of the positioning slider 20 is positioned with the groove 29, and the positioning slider 20 cannot move. As the left pulling force of the first connecting rod 19 is zero, the right elastic force of the extrusion spring 30 is much greater than the left pushing force of the second connecting rod 21. At this time, due to the chamfer of the surface of the block 33, the block 33 begins to shrink, thereby causing the positioning slider 20 to move to the right and eventually blocking the conical sealing plug 28. After being blocked, the small float 24 begins to fall due to the low liquid level of the treated liquid, so that the treated liquid delivery port 22 is directly connected to the treatment box 11 at this time, thereby ensuring that the treated liquid can be injected in time.
