Description

Technical Field

[0001] The present invention relates to the technical field of mixed acid separation, and particularly to a mixed acid separation device. Background Art

[0002] Mixed acid, also known as mixed acid and superacid, is obtained by mixing two or more specific acids in a specific ratio and in a specific mixing manner for a specific purpose and is used in a specific chemical or technological process. Generally, it is a mixture of two strong acids. In many cases, the acidity or certain properties will be enhanced after mixing, but not necessarily. For example, when nitric acid and hydrosulfuric acid are mixed, sulfur and nitrogen dioxide are generated, and the acidity can disappear, but this mixing has no practical significance. Aqua regia is a colorless liquid mixed acid formed by mixing one volume of concentrated nitric acid and three volumes of concentrated hydrochloric acid. It has strong oxidizing and strong complexing properties and can dissolve precious metals such as gold and platinum. It is mainly used in analytical chemistry to dissolve minerals and certain insoluble sulfides and to wash glassware. Its performance is unstable and it needs to be prepared immediately before use. The mixed acid prepared from nitric acid and sulfuric acid has a wide range of uses and is mainly used in the nitration reaction of organic compounds, especially in the manufacture of nitroaromatic compounds and nitroglycerin. The mixed acid of concentrated nitric acid and concentrated sulfuric acid is simply called nitrosulfuric acid and is a nitrating agent. Nitrating agents also include mixed acids prepared from nitric acid and other strong protonic acids such as acetic acid, acetic anhydride, perchloric acid, trifluoromethanesulfonic acid, etc.

[0003] For example, the patent document with the publication number CN 217448993 U discloses an organic mixed acid separation and purification device, which includes: a distillation column, the upper part of the distillation column is connected with a mixed acid inlet pipe, the top is connected with a first gas outlet pipe, and the bottom is connected with a first liquid outlet pipe; a reboiler; a circulation pump; a first separation tank, the bottom of the first separation tank is connected with a second liquid outlet pipe and a reboiler outlet pipe. The reboiler outlet pipe includes a main pipe connected to the reboiler, a first branch pipe connected to the main pipe and communicating with the distillation column, and a second branch pipe connected to the main pipe and communicating with the first separation tank; a demisting component, the demisting component at least includes a primary demister installed on the main pipe; a second separation tank, the middle part of the second separation tank is connected with the first gas outlet pipe, its bottom is connected with a reflux pipe communicating with the distillation column, and the top is connected with a second gas outlet pipe; a hydrochloric acid absorption component. It can achieve the efficient separation of hydrochloric acid and organic acid in the organic mixed acid, and the product has high purity; the obtained organic acid can be directly used according to the requirements of downstream process products or further rectified and dehydrated.

[0004] However, when this structure is actually used for separating mixed acids, due to the limitations of its own structure, it often can only adopt a simple separation operation of separating the mixed acids layer by layer through reaction and then extracting them one by one. It is impossible to perform a synchronous and efficient separation operation on two layers of separated mixed acids, which leads to the need to wait for a long time for the mixed acids to separate and discharge liquid inside the equipment, affecting the overall processing efficiency of the equipment. At the same time, when the equipment is separating mixed acids, it is impossible to perform an efficient internal eddy current stirring and mixing operation, which cannot ensure a more sufficient reaction of the mixed acids, and subsequent more thorough separation operations cannot be carried out, unable to meet the daily use requirements. Therefore, it is urgent to design a mixed acid separation device to solve the above problems. Summary of the Invention

[0033] Working principle: When in use, the operator first feeds the mixed acid raw material to be processed as a whole through the feed valve seat 25 on the front of the central tank body 1. Then, reactions and upper and lower stratification operations are carried out inside the tank body composed of the central tank body 1, the upper tank body 2, and the lower tank body 3. When the complete stratification is achieved inside the central tank body 1, the upper tank body 2, and the lower tank body 3, the upper and lower separation operation of the mixed acid inside can be carried out. At this time, the air control pump 14 at the center inside the U-shaped frame 9 can be started to perform air charging and discharging control operations from the air control grid groove 15. Then, the air flow conducts upper and lower diversion operations along the branch air pipes 16 at the upper and lower ends of the air control pump 14, and then conducts diversion operations along the guide air pipes 17 at the upper and lower ends of the U-shaped frame 9, and finally enters the inside of the upper and lower air control top seats 5 to perform the air charging and discharging control operation of the air support rod 6, which also enables the telescopic seat 7 and the annular liquid suction head 8 inside the receiving socket 4 to perform lifting and adjusting operations, and can perform liquid suction and discharging operations at various depth positions inside the central tank body 1, the upper tank body 2, and the lower tank body 3, and export the two separated mixed acids from the discharge valve seats 24 on the front of the upper and lower air control top seats 5 respectively. At the same time, during daily use, the real-time observation of the liquid level change can be carried out from the first observation mirror 26 on the side of the central tank body 1 and the second observation mirrors 31 on the sides of the upper tank body 2 and the lower tank body 3, and then the control of the air support rod 6 can be adjusted accordingly to ensure the efficient liquid discharging operation with upper and lower synchronization inside the equipment, and perform the efficient separation operation of the mixed acid inside the central tank body 1, the upper tank body 2, and the lower tank body 3. During the daily use process, when the mixed acid to be separated enters the central tank body 1 through the feed valve seat 25, the mixed acid raw material can first perform uniform annular feeding operation through the annular feed frame 29 on the inner wall of the central tank body 1 to ensure the uniformity of the raw materials inside the central tank body 1, the upper tank body 2, and the lower tank body 3. When the mixed acid is completely fed in, the operator can start the drive motor 11 on the surface of the drive unit 10 to drive the drive gear 12 at the bottom to rotate and adjust around the damping rotating shaft 13, so as to drive the rotating gear ring 28 at the center inside the central tank body 1 to rotate and adjust, and drive the annular feed frame 29 and the eddy current blades 30 inside to rotate and adjust, which also makes the mixed acid inside the central tank body 1 get eddy stirring operation, so that the mixed acid is fully stirred and mixed inside the central tank body 1, the upper tank body 2, and the lower tank body 3, thereby improving the subsequent effect of mixed acid stratification and separation. At the same time, during daily use, the central tank body 1, the upper tank body 2, and the lower tank body 3 can be hermetically connected and docked through the second sealing rings 23 at the upper and lower ends and the connecting seat 21 and the first sealing ring 22 at the bottom of the receiving socket 4.
