Description

Technical Field

[0001] The utility model relates to the technical field of sulfuric acid production reactors, in particular to an explosion-proof reactor for sulfuric acid production. Background Art

[0002] Sulfuric acid is an important chemical raw material with a wide range of uses. It is mainly used in the fertilizer industry (such as phosphate fertilizer and nitrogen fertilizer), metallurgy, petroleum, light industry, organic synthesis and other fields. There are various methods for producing sulfuric acid, but the current mainstream method is the contact method, which uses a series of complex process flows such as flue gas purification, drying, conversion and absorption to finally produce sulfuric acid.

[0003] In the production process of sulfuric acid, the reactor is one of the key equipment. It is responsible for key process steps such as reaction, mixing and storage. However, sulfuric acid production is characterized by high temperature, high pressure and strong corrosiveness. These conditions are very likely to cause safety accidents, especially explosion accidents. At present, in order to achieve the explosion-proof effect of the reactor, the shell of the reactor is usually made of high-strength alloy material that can withstand high pressure and temperature. At the same time, its lid also adopts an explosion-proof design with good sealing and explosion-proof performance, and can remain stable even under high temperature and high pressure.

[0004] However, this type of explosion-proof reactor only makes improvements in material. Although the explosion-proof performance is improved, it lacks the corresponding pressure relief components. If the pressure is too high, although the reactor can withstand the large pressure, other electronic devices installed in the reactor are easily damaged by the pressure. In addition, although some explosion-proof reactors are equipped with pressure relief components, the pressure relief part is directly connected to the outside world and lacks the corresponding sulfuric acid gas treatment components. As a result, the corresponding sulfuric acid production gas is also directly discharged to the outside, polluting the environment and causing inconvenience to users. In view of this, we propose an explosion-proof reactor for sulfuric acid production. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1-4The utility model provides a technical solution: an explosion-proof reactor for sulfuric acid production, comprising a reactor body 1, a pressure relief assembly 2 provided on the reactor body 1, the pressure relief assembly 2 comprising an exhaust gas treatment cylinder 20, an exhaust pipe 21 fixedly mounted at the center of the exhaust gas treatment cylinder 20, a conducting pipe 22 fixedly mounted at one end of the exhaust pipe 21, the end of the conducting pipe 22 fixedly mounted on the reactor body 1, a pressure relief valve 23 fixedly mounted on the conducting pipe 22, the pressure relief valve 23 being used to relieve pressure in the reactor body 1, thereby achieving a pressure relief explosion-proof protection effect;

[0027] Specifically, a drain pipe 26 is fixedly mounted on the bottom cylinder of the exhaust gas treatment cylinder 20, and a second valve 261 is fixedly mounted on the drain pipe 26, so that the second valve 261 can be opened to discharge the waste gas treatment cylinder 20;

[0028] Specifically, a purified gas pipe 25 is fixedly installed on the top of the waste gas treatment cylinder 20, and the purified gas pipe 25 is used to handle the discharge operation of the purified air; a booster pump 27 is provided on one side of the waste gas treatment cylinder 20, and a delivery pipe 28 is fixedly installed on the water outlet end of the booster pump 27. The end of the delivery pipe 28 penetrates into the waste gas treatment cylinder 20 and is fixedly installed with two symmetrical liquid medicine pipes 29 on the left and right. A plurality of nozzles 291 arranged at equal intervals are fixedly installed on the bottom of the liquid medicine pipe 29, and a suction pipe 271 is fixedly installed on the water inlet end of the booster pump 27. The suction pipe 271 is connected to an external liquid medicine delivery pipeline to realize the delivery of liquid medicine for spraying the waste gas.

[0029] In this embodiment, an air outlet hood 211 is fixedly installed at the other end of the exhaust pipe 21. The air outlet hood 211 is located in the exhaust gas treatment tube 20. The air outlet hood 211 is in the shape of an inverted funnel. Half the height of the air outlet hood 211 extends below the liquid level in the exhaust gas treatment tube 20, so that the exhaust gas in the air outlet hood 211 reacts more fully with the liquid medicine.

[0030] Furthermore, a pressure gauge 13 is fixedly installed on the top of the reactor body 1, and a feed pipe 10 is fixedly installed on the top cylinder of the reactor body 1. The pressure gauge 13 is used to detect the pressure in the reactor body 1, and the feed pipe 10 is used for adding raw materials.

[0031] In addition, a discharge pipe 11 is fixedly installed on the bottom cylinder of the reactor body 1, and a first valve 12 is fixedly installed on both the feed pipe 10 and the discharge pipe 11 to facilitate the unloading operation at the discharge pipe 11.

[0032] It is worth noting that the terminal end of the purified gas pipe 25 is set to face downward, and a gas detection sensor 251 is fixedly installed on the purified gas pipe 25, so that the gas detection sensor 251 can be used to detect whether the gas discharged from the purified gas pipe 25 contains corresponding toxic gas.

[0033] It is worth noting that an alarm 24 is fixedly installed on the top of the waste gas treatment tube 20, and a control host 201 is fixedly installed on the waste gas treatment tube 20. When the gas detection sensor 251 detects excessive gas, the gas detection sensor 251 sends data to the control host 201, and the control host 201 controls the alarm 24 to sound an alarm, prompting the staff to replace the waste liquid in the waste gas treatment tube 20 in time.

[0034] Finally, it should be noted that the components involved in the present invention, such as the alarm 24, gas detection sensor 251 and control host 201, are all universal standard parts or components known to those skilled in the art. Their structures and principles are known to those skilled in the art through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adapted controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the present invention. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the art.

[0035] When the explosion-proof reactor for sulfuric acid production of the present invention is in use, as the pressure in the reactor body 1 increases, the pressure relief valve 23 will automatically open. At this time, the high-pressure gas in the reactor body 1 enters the exhaust gas treatment tube 20 along the exhaust pipe 21. The exhaust gas in the exhaust pipe 21 flows to the gas outlet hood 211 and first reacts with the liquid medicine in the exhaust gas treatment tube 20. In addition, the booster pump 27 is connected to an external power supply and is made to work. When the booster pump 27 works, the liquid medicine is sucked into and sprayed out from the nozzle 291, thereby further treating the exhaust gas. The treated gas is discharged outward along the purified gas pipe 25, thereby realizing pressure relief explosion-proof protection.

[0036] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
