Description

TECHNICAL FIELD

[0001] The present application relates to an equipment for industrial production, in particular to a cylindrical hollow up-down structure flash cooling concentration crystallization defoamer, which has the functions of flash evaporation, cooling and defoaming, and can be used for flash evaporation, cooling, concentration, crystallization and defoaming of fluid, and can be widely arranged in the process of industrial production. BACKGROUND

[0002] In industrial production, flash evaporation, concentration, cooling and solution crystallization of fluid are often used. In order to achieve this purpose, a cylindrical hollow structure flash cooling concentration crystallizer is usually used. Through the flash cooling concentration crystallizer, a large amount of liquid can be evaporated and discharged from the flash cooling concentration crystallizer, sometimes reaching an evaporation capacity of ≥1.3t / (m 2 The flash cooling liquid is thus concentrated and cooled, and the flash cooling liquid that needs to be crystallized is thus crystallized, so as to achieve the purpose of separating different components. The flash cooling liquid from the system that needs to be treated is added to the flash cooling concentration crystallizer through the flash cooling liquid inlet, the treated flash cooling liquid flows out of the flash cooling concentration crystallizer through the flash cooling liquid outlet cone and the vortex-breaking cross baffle, and the evaporated gas is discharged through the outlet at the top end of the flash cooling concentration crystallizer. Since the evaporated gas contains a large amount of liquid foam, not only the flash cooling liquid is wasted, but also the purity of the evaporated and discharged gas is affected. In order to improve the working efficiency of the flash cooling concentration crystallizer, an independent cylindrical hollow structure defoamer is arranged after the flash cooling concentration crystallizer in current industrial production. Although the working efficiency can be ensured, two independently arranged devices not only increase the height of the plant, but also increase the span of the plant, increase the length of the connecting pipeline and the resistance loss along the way, and increase the difficulty of maintenance, maintenance and replacement of parts.
