Description

Technical Field

[0001] The utility model relates to a processing system, in particular to a detachable concentrated sulfuric acid mist absorption device. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Concentrated sulfuric acid storage tanks are widely used in major chemical companies. Small breathing caused by changes in ambient temperature and large breathing caused by loading and unloading will produce acid mist, which will cause corrosion of equipment around the storage tank and may eventually lead to safety accidents. Air will enter the storage tank during the transportation of concentrated sulfuric acid, so moisture in the air will also be brought in, affecting the concentration of concentrated sulfuric acid. Compared with concentrated hydrochloric acid, concentrated sulfuric acid is less volatile and more hygroscopic. Therefore, when considering the absorption of acid mist, the water absorption of concentrated sulfuric acid cannot be ignored. The hydrochloric acid mist absorber uses the property of hydrochloric acid being highly soluble in water, and uses long-flowing water in a closed container to contact the gas discharged from the storage tank, thereby completing the absorption of its acid mist. Obviously, this method is not suitable for concentrated sulfuric acid with weak volatility, and will increase the water absorption of concentrated sulfuric acid. Utility Model Content

[0004] In order to solve the deficiencies of the prior art, the utility model provides a detachable concentrated sulfuric acid mist absorption device, which effectively improves the efficiency of acid mist absorption and reduces the water absorption of concentrated sulfuric acid.

[0005] The utility model adopts the following technical solutions:

[0006] A detachable concentrated sulfuric acid mist absorption device comprises an absorption tower, the top of the absorption tower is an exhaust elbow, the upper part is provided with a detachable lime baffle I, the bottom is provided with a detachable lime baffle II, and the bottom of the absorption tower is inserted with an acid mist inlet pipe.

[0007] Furthermore, the acid mist inlet pipe extends into the absorption tower, the top height of which is lower than the lime baffle I, and the top of the acid mist inlet pipe is sealed, and a number of openings are evenly arranged on both sides. The acid mist enters the acid mist inlet pipe from the acid mist inlet and enters the absorption tower from the side of the acid mist inlet pipe. Part of the acid mist and water vapor is absorbed by the quicklime on the lime baffle at the bottom, and the other part rises to the top and is absorbed by the quicklime on the upper lime baffle. The treated gas is discharged from the exhaust port of the exhaust elbow.

[0008] Furthermore, the lime baffle I is adapted to the size of the absorption tower, and air holes are arranged on the lime baffle.

[0009] Furthermore, the central air hole is arranged at the center of the lime baffle, and the rest are evenly distributed around the central air hole.

For example, it can be a fixed connection, a detachable connection, or an integral whole; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; it can be an internal connection between two elements, or an interaction relationship between two elements. For ordinary technicians in this field, the specific meaning of the terms in the present utility model can be understood according to the specific circumstances.

[0019] Example

[0020] The utility model proposes a detachable concentrated sulfuric acid mist absorption device to solve the technical problems in the background technology on the basis of the prior art. The top of the absorption tower is an exhaust elbow 1, and a detachable lime baffle Ⅰ2 is arranged on the upper part. The lime baffle Ⅰ is adapted to the size of the absorption tower. The lime baffle is provided with air holes. The size of the air holes is very small, which can effectively retain the gas. At this time, the acid mist and water vapor in the gas are fully absorbed. The central air hole is arranged at the center of the lime baffle, and the rest are evenly distributed around the central air hole. The bottom is a detachable lime baffle Ⅱ3, and the bottom of the absorption tower is inserted into the acid mist intake pipe 4. The acid mist intake pipe extends into the absorption tower, and the top height is lower than the lime baffle Ⅰ. Moreover, the top of the acid mist intake pipe is sealed, and a number of openings are evenly arranged on both sides.

[0021] The process of this technology is:

[0022] The acid mist enters the acid mist inlet pipe from the acid mist inlet a, and enters the absorption tower from the side opening of the acid mist inlet pipe. Part of the acid mist and water vapor is absorbed by the quicklime on the lime baffle at the bottom, and the other part rises to the top and is absorbed by the quicklime on the upper lime baffle. The treated gas is discharged from the exhaust port b of the exhaust elbow.

[0023] The air holes on the lime baffle allow the gas to be retained for a certain period of time. The quicklime on the lime baffle in the device can effectively absorb the acid mist and water vapor in the gas. The quicklime after use becomes a neutral salt solution and will not pollute the environment.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
