Technical Field
[0001] This utility model relates to the field of phenol and acetone processing technology, specifically to a distillation device for phenol and acetone processing. Background Technology
[0002] In the field of phenol and acetone processing, distillation is a key step. Traditional distillation equipment has high energy consumption and poor separation efficiency, making it difficult to meet the growing production demands and energy-saving standards. Moreover, under complex operating conditions, the equipment has poor stability and is prone to failure, affecting the continuity of production. Developing efficient, energy-saving and stable distillation equipment for phenol and acetone processing is of great significance to improving the overall efficiency of the industry.
[0003] According to a patent application published on the internet (authorization announcement number: CN221332803U), "This utility model relates to the field of phenol and acetone processing technology, and proposes a distillation device for phenol and acetone processing, including a distillation column, a condenser, and a collection tank. A guide pipe is connected to the top of the distillation column, which is connected to the inlet of the condenser. The outlet of the condenser is connected to the collection tank. The condenser is mounted on the collection tank via a bracket. The device also includes a temporary storage box, which is fixedly installed on the top of the distillation column and the ground via support legs; an electromagnetic valve pipe, which connects the bottom of the temporary storage box to the distillation column; an intercepting mesh plate, which is installed inside the temporary storage box and divides the internal space of the temporary storage box into upper and lower areas; and a stirring plate. This technical solution solves the problem that the distillation column used for acetone processing has the disadvantage of being difficult to filter, leading to a large amount of particles and impurities easily mixing into the acetone raw material during processing, affecting the quality of the acetone raw material processing and the product yield, and reducing the efficiency of subsequent processing."
[0004] Based on the above, the applicant believes the following deficiencies exist:
[0005] The device does not treat the crude solution entering the device. When the crude solution is distilled, a large amount of precipitate will accumulate, sink to the bottom, or adhere to it. These situations will affect the overall distillation effect of the device and result in incomplete distillation of the crude solution. Utility Model Content

Once the crude solution is added into the distillation tank, the device can be started. The crude solution inside the distillation tank is heated and distilled through an external heating jacket. The stirring shaft is driven by a motor to rotate, which drives the anchor frame stirring paddle at the bottom to stir and stir up the precipitate inside the crude solution. This can effectively prevent a large amount of precipitate from settling to the bottom and affecting the distillation effect. At the same time, the scraper is tightly attached to the inner wall of the distillation tank by springs and telescopic columns, which can effectively prevent precipitate from adhering during the distillation process. The rotation of the scraper will drive the crude solution to rotate synchronously, which can effectively improve the heating efficiency of the crude solution.
[0016] The distillation equipment for phenol and acetone processing is equipped with a bottom liquid and residue filtration and discharge component. After distillation is completed, the discharge valve can be activated to discharge the bottom liquid and residue from the distillation tank. The residue and bottom liquid are separated by a detachable filter frame. Later, the fixing bolts are removed to separate the filtration tank and the detachable bottom tank.

[0033] In actual operation, when this device is in use, liquid is added into the distillation tank 1 through the feed pipe 2.

[0035] The hot gas from the distillation process escapes from the distillation tank 1 through the exhaust port 81 and the gas delivery pipe 82 and enters the condenser 83. At this time, the water inlet pump 89 and the recovery pump 802 are started, which drives the condensate to pass through the heat exchange tube 85. The hot gas quickly condenses into water when it encounters the cold. Later, the condensate product discharge valve 804 is opened to discharge the product, thus completing the efficient distillation of the crude solution.
