Description

Technical Field

[0001] The utility model belongs to the technical field of benzotriazole production equipment, in particular to a continuous distillation device used for benzotriazole production. Background Art

[0002] Benzotriazole needs to be purified by distillation equipment. Distillation is a separation process that uses the different volatilities of the components in a mixture to separate the components. Commonly used equipment includes plate distillation towers and packed distillation towers.

[0003] A distillation tower is a tower-type gas-liquid contact device for distillation. By utilizing the different volatilities of the components in the mixture, that is, the different vapor pressures of the components at the same temperature, the light components and low-boiling substances in the liquid phase are transferred to the gas phase, while the high-boiling and heavy components in the gas phase are transferred to the liquid phase, thereby achieving the purpose of separation. Due to the complex distillation structure of conventional distillation towers, the practicality of conventional distillation equipment is relatively low.

[0004] Therefore, we propose a continuous distillation device for benzotriazole production to solve the above problems. Utility Model Content

[0010] Preferably, the gas collecting hood includes a hood body and a first sealing grid, wherein the first sealing grid is fixedly connected to the lower end of the hood body. When the evaporated gas enters the hood body, it is guided into the tank body through the hood body, so that the evaporated gas enters the tank body, thereby facilitating the collection of the evaporated gas into the gas guide groove.
