Description

Technical Field

[0001] The utility model relates to the technical field of hydrochloric acid distillation, in particular to an anti-corrosion hydrochloric acid distillation device. Background Art

[0002] Hydrochloric acid is an aqueous solution of hydrogen chloride. It is a colorless, transparent liquid with a strong pungent odor and high corrosiveness. Hydrochloric acid is widely used in chemical raw materials, dyes, medicine, food, printing and dyeing, leather, sugar making, metallurgy and other industries. It is also used in the regeneration of ion exchange resins and as a cleaning agent for electroplating and metal surfaces.

[0003] Hydrochloric acid distillation is done by feeding the raw hydrochloric acid into a reboiler and heating it with a built-in pure tantalum liner heater, which vaporizes part of the liquid phase to form hydrochloric acid vapor. The vaporized hydrochloric acid vapor enters the distillation tower, where continuous distillation is carried out to separate a high-concentration mixture of hydrogen chloride gas and water vapor. The inner wall of the distillation tower is prone to residual raw materials. If these residual raw materials are not cleaned in time, they will affect the next distillation result.

When the inner wall of the distillation kettle needs to be cleaned, the pull rod is pulled, and the pull rod drives the card block to slide. After the limit block loses the restriction of the card block, it is retracted into the slide groove through the first spring. At this time, the top cover can be removed to clean the interior. After the cleaning is completed, the positioning column and the positioning block are pre-positioned, and then the shift block is pushed to drive the limit block to slide. The top of the limit block squeezes the inclined surface of the card block to make the card block slide into the first slide groove.
