The invention provides a crystallization and condensation all-in-one device. The crystallization and condensation all-in-one device comprises a crystallizer and a condenser, wherein a steam outlet, afeed opening and a discharge opening are formed in the crystallizer; the condenser is arranged above the condenser, the steam outlet extends into the condenser, and the external diameter of the steamoutlet is smaller than the internal diameter of the condenser in the position of the steam outlet; sprayers and a water knockout trap for preventing cooling water sprayed out of the sprayers from entering the steam outlet are arranged in the condenser; a noncondensable gas outlet is formed in the upper part of the condenser; a circulating cooling water outlet is formed in the lower part of the condenser; and the position of the upper edge of the circulating cooling water outlet is lower than that of the steam outlet. According to the crystallization and condensation all-in-one device, a condenser and a crystallizer which are mutually independent in traditional equipment are integrated, so that pipelines connected between the two containers are reduced, further, pipeline resistance is reduced, secondary steam evaporated or flashed by the crystallizer directly enters the condenser, and efficient evaporation or flash evaporation crystallization is realized.
Description
technical field [0001] The invention belongs to the field of solid-liquid separation, and in particular relates to an integrated device for crystallization and condensation. Background technique [0002] The existing condenser and evaporation or flash cooling crystallizer are independent of each other, and are respectively a heat exchanger for condensing evaporation or flash secondary steam into liquid and an equipment for evaporative concentration or flash cooling to cause crystal precipitation. The above two sets of devices have different working properties, but they are inseparable in the whole production system. The evaporation or flash crystallizer needs to be used in conjunction with the mixing condenser to maintain the working pressure required by the evaporation or flash crystallizer. However, the two devices themselves are large in size and have a certain length, occupying a large space, and thus require a long pipeline to connect the two devices, and the outside of...
