The invention relates to the technical field of purifying substances in a melting crystallization mode, in particular relates to a novel double-falling-film melting crystallizer. One end of an upper shell is communicated with a cooling-heating medium inlet; one end of a lower shell is communicated with a cooling-heating medium outlet; an outer tube is communicated between the upper shell and the lower shell; an inner tube is arranged in an outer tube in a sleeving manner; the part between the outer tube and the inner tube is filled with a cooling-heating medium; an outer tube pull rod is arranged in the outer tube; the two ends of the outer pull rod are connected to the upper shell and the lower shell respectively; an outer tube falling film head is arranged on the outer shell in a sleeving manner, and is provided with outer tube falling film holes; an inner tube pull rod is arranged in the inner tube; the two ends of the inner tube pull rod are connected to the upper shell and the lower shell respectively; and an inner tube falling film head is arranged on the inner tube, and is provided with inner tube falling film holes. The novel double-falling-film melting crystallizer provided by the invention ensures that the liquid that cannot form a film can be redistributed to prevent non-uniform film forming caused by crystallization so as to ensure a film forming heat transfer effect.
Description
technical field [0001] The invention relates to the technical field of material purification by melting crystallization, in particular to a novel double falling film melting crystallizer and a material separation process. Background technique [0002] At present, there are various forms of melting crystallizers. The melting crystallizers include drum crystallizers, surface continuous crystallizers (casing crystallizers), horizontal melting crystallizers, and falling film crystallizers. Falling film melting crystallizer has received more and more attention for its continuous high efficiency. [0003] The double falling film melting crystallizer has the characteristics of more accurate temperature control and continuous operation. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a new type of double falling film melting crystallizer to ensure that the liquid that does not form a film can be re...
