Abstract

The invention discloses a crystallization tower for gas phase reaction. The crystallization tower comprises an upper seal head, a tower body and a lower seal head, wherein a gas outlet is formed in the upper seal head; a gas inlet and a material outlet are formed in the lower seal head; the tower body comprises a cooling section and a crystallizing section from bottom up; a heat removing assembly is arranged in the cooling section; a tower tray is arranged in the crystallizing section; the tower tray comprises a tower tray plate and a crystallizing column fixed on the tower tray plate. The crystallization tower provided by the invention has a large surface area capable of being attached with crystal substances, has crystals easy to remove and stack on the tower tray, is suitable for the crystallization process of ammonium hydrosulfide during acid water treatment in a refinery plant, and is especially suitable for the separation process of hydrogen sulfide in an acid gas containing carbon dioxide.

Description

technical field [0001] The invention relates to a crystallization device for gas-phase reaction, belonging to the field of chemical equipment, in particular to a crystallization tower for treating two kinds of gases to react to generate solid phase. Background technique [0002] Crystallization is the process of precipitating solid matter in a crystalline state from a vapor, solution or melt, and has been used to extract table salt from seawater for thousands of years. According to statistics, in modern society, about 2 / 3 of the bulk chemical products are solid products, especially in the pharmaceutical industry, 85% of the products are solid products, and the production process of these solid products is inseparable from crystallization operate. Traditional industrial crystallization research fields can generally be divided into four categories, namely solution crystallization, melt crystallization, precipitation crystallization and sublimation crystallization. [0003] C...
