Description

Technical Field

[0001] This utility model relates to the field of artificial sunflower seed musk processing technology, specifically to a nitration reaction acid separation device. Background Technology

[0002] Synthetic sunflower musk belongs to the nitromusic compound class and has an amber-like musky aroma. It is mainly used as a fixative in fragrances and is suitable for products such as perfumes, soaps, and detergents. In the manufacturing of synthetic sunflower musk, an acid separation process is usually required, which necessitates the use of an acid separation device.

[0003] A search revealed that the announcement number is CN221619434U, and the name is "Mixed Acid Preparation Apparatus for Nitrification Reaction," which includes a reaction shell. Research and analysis revealed that although it has the advantage of avoiding excessive heat from affecting the nitration reaction and thus improving the reaction efficiency, it also has the following disadvantages to some extent.

[0004] For example, during the use of this device, it is inconvenient to add concentrated sulfuric acid and concentrated nitric acid separately. During the addition process, concentrated sulfuric acid and concentrated nitric acid will react, which can easily affect the reaction results. Moreover, when the injection of concentrated sulfuric acid and concentrated nitric acid is stopped, the concentrated sulfuric acid and concentrated nitric acid will not flow in the pipeline and may crystallize, which can easily cause blockage of the pipeline and make it inconvenient for people to use. In order to solve the above technical problems, we designed a nitration reaction acid separation device. Utility Model Content

It solves the problems of the device not being convenient to separate the addition of concentrated sulfuric acid and concentrated nitric acid during use, the concentrated sulfuric acid and concentrated nitric acid reacting during the addition process, which can easily affect the reaction results, and the concentrated sulfuric acid and concentrated nitric acid not flowing in the pipeline when the injection of concentrated sulfuric acid and concentrated nitric acid is stopped, which can easily cause crystallization and blockage of the pipeline, making it inconvenient for people to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a nitration reaction acid separation device, comprising a base plate, a support leg bolted to the top of the base plate, a cooling shell welded to the top of the support leg, a reaction shell welded to the inner cavity of the cooling shell, a top plate bolted to the top of the reaction shell, a diversion pipe extending through the top of the top plate, a partition welded to the inner cavity of the diversion pipe, a sealing plate bolted to the top of the diversion pipe, a first spray head sleeved on the surface of the diversion pipe, the top of the first spray head communicating with the diversion pipe, and the diversion pipe... The bottom of the base plate is connected to a second spray head. A cooling box is bolted to the rear side of the top of the base plate. A water pump is bolted to the front side of the cooling box. A semiconductor cooler is bolted to the rear side of the cooling box. A mounting bracket is welded to the top of the base plate. Storage tanks are bolted to both sides of the top of the mounting bracket. An acid pump is bolted to the top of the storage tank. The outlet pipe of the acid pump is connected to a three-way solenoid valve through a pipe. The front side of the three-way solenoid valve is connected to a diversion pipe through a pipe. The front side of the storage tank is connected to the three-way solenoid valve through a pipe.

[0007] Preferably, the bottom of the reaction shell is bolted to a support block, and the bottom of the support block is bolted to the cooling shell.

[0008] Preferably, a cooling fan is bolted to the rear side of the semiconductor cooler, and a discharge valve is connected to the right side of the reaction shell.

[0009] Preferably, the pump's suction pipe is connected to the cooling tank via a pipe, the pump's discharge pipe is connected to the cooling shell via a pipe, and the rear side of the cooling shell is connected to the cooling tank via a pipe.

[0010] Preferably, the pumping pipe of the acid pump is connected to the storage tank through a pipe, and a sealing gasket is provided at the bottom of the sealing plate and the connection of the diversion pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention involves adding concentrated sulfuric acid and concentrated nitric acid into a storage tank, and then using an acid pump to extract the liquid from the tank. When manufacturing is required, a three-way solenoid valve connects the outlet pipe of the acid pump to a distribution pipe, allowing the acid pump to inject concentrated sulfuric acid and concentrated nitric acid into both sides of the distribution pipe's inner cavity. The distribution pipe then injects the concentrated sulfuric acid and concentrated nitric acid into the first and second spray heads, respectively, ensuring even spraying for mixing and reaction. When manufacturing is not required, the concentrated sulfuric acid and concentrated nitric acid in the pipe before the three-way solenoid valve flow into the distribution pipe and are injected into the reaction chamber through the first and second spray heads. The three-way solenoid valve connects the outlet pipe of the acid pump to the storage tank, allowing the liquid in the pipe after the three-way solenoid valve to circulate, effectively preventing the concentrated sulfuric acid or concentrated nitric acid from crystallizing due to prolonged stagnation in the pipe. This invention addresses the issue of a large amount of heat being released during the reaction of concentrated sulfuric acid and concentrated nitric acid. A semiconductor cooler is used to cool the water in the cooling tank, and a water pump extracts the cold water from the cooling tank and injects it into the cooling shell. The cold water in the cooling shell absorbs the heat from the reaction shell, thus cooling the reaction shell and effectively preventing the temperature inside the reaction shell from becoming too high. The cooled water then flows back into the cooling tank for reuse. Attached Figure Description

The rear side of the cooling shell 2 is connected to the cooling tank 10 via a pipe.

When manufacturing is required, the outlet pipe of the acid pump 16 is connected to the distribution pipe 5 via the three-way solenoid valve 17. The acid pump 16 injects concentrated sulfuric acid and concentrated nitric acid into both sides of the inner cavity of the distribution pipe 5.

The first spray head 7 and the second spray head 8 spray the concentrated sulfuric acid and concentrated nitric acid evenly to facilitate their mixing and reaction. When manufacturing is not required, the concentrated sulfuric acid and concentrated nitric acid in the pipe before the three-way solenoid valve 17 flow into the distribution pipe 5 and are then sprayed through the first spray head 7 and the second spray head 8. The first spray head 7 and the second spray head 8 are injected into the reaction shell 3. The outlet pipe of the acid pump 16 is connected to the storage tank 15 through the three-way solenoid valve 17, so that the liquid in the pipe behind the three-way solenoid valve 17 circulates.

The cold water in the cooling tank 10 is pumped out by the water pump 11 and injected into the cooling shell 2. The cold water in the cooling shell 2 absorbs the heat in the reaction shell 3, thereby cooling the reaction shell 3 and effectively preventing the temperature in the reaction shell 3 from becoming too high.
