Description

Technical Field

[0001] The utility model relates to the technical field of dry chlorine gas dehydration and drying, in particular to a dry chlorine gas dehydration and drying device. Background Art

[0002] Chlorine has a higher density than air, is soluble in water and alkaline solutions, is easily soluble in organic solvents and is easily compressed, and can be liquefied into yellow-green oily liquid chlorine. It is one of the main products of the chlor-alkali industry and can be used as a strong oxidant. Since most of the chlorine produced in the industry contains a large amount of water and is extremely corrosive, the investment in the selection of equipment, pipelines and other materials is too large. Therefore, the dehumidification of wet chlorine is extremely important in industry.

[0003] Chlorine dehydration and drying generally include 1. Dehumidification adsorption drying method, which uses various adsorbents such as silica gel, molecular sieves, etc. to absorb moisture in chlorine. The advantage of this method is good drying effect, but the adsorbent needs to be replaced or regenerated regularly, which increases the operating cost. 2. Chemical drying method: Another commonly used chlorine drying method, which removes moisture from chlorine through chemical reactions. Commonly used chemical desiccants include concentrated sulfuric acid, calcium lime, etc. This method can achieve continuous operation, but the solid waste generated is more troublesome to handle and has a certain impact on the environment. 3. Cooling condensation method: This method cools the chlorine to lower its temperature, thereby condensing the moisture to achieve the purpose of drying. The disadvantage of this method is that it has high energy consumption and limited processing capacity for chlorine in extremely low temperature environments.

[0004] However, existing chlorine dehumidification devices have certain shortcomings: chlorine is usually dehydrated using acidic sulfuric acid, but the contact effect with sulfuric acid is average, which makes the dehydration effect average, and thus reduces the dehydration efficiency. At the same time, too fast chlorine flow rate may cause eddy currents or impacts in the pipeline, which may cause damage to the equipment and even cause safety accidents. Utility Model Content
