Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a gas guide device for a hydrogen fluoride reaction furnace. Background Art

[0002] In the chemical production process, the hydrogen fluoride reactor plays a vital role as the core equipment for producing hydrogen fluoride. Hydrogen fluoride is a raw material widely used in many chemical fields and is of great significance to the development of the entire chemical industry. The main function of the hydrogen fluoride reactor is to provide a suitable reaction environment so that the fluoride salt ore can undergo reduction and fluorination reactions at high temperatures to generate hydrogen fluoride gas. In this process, the temperature, pressure and other parameters in the reactor need to be precisely controlled to ensure the smooth progress of the reaction and the purity of the product.

[0003] However, in the production process of hydrogen fluoride, the high-temperature gas produced by the reactor often contains a certain amount of dust and impurities. These dust and impurities can easily cause blockage to subsequent production equipment, affecting production efficiency, and also cause wear and tear on the equipment, shortening the service life of the equipment. In addition, the discharge of untreated hydrogen fluoride gas into the environment will also cause environmental pollution and increase environmental risks. For this reason, we propose a gas guide device for a hydrogen fluoride reactor. Utility Model Content
