Abstract

The invention relates to the technical field of devices for producing large-grained ammonium sulfate, in particular to an integrated forced circulation crystallizing evaporator for producing large-grained ammonium sulfate and a device. The integrated forced circulation crystallizing evaporator comprises a first evaporator, a second evaporator and a crystallizer, the crystallizer is sequentially connected with a first conical portion, a cylinder portion and a second conical portion from top to bottom, a wire mesh demister is arranged at a joint of the first conical portion and the cylinder portion, the crystallizer is divided into a vaporizing chamber and a crystallizing chamber by the wire mesh demister, the taper of the second conical portion is larger than that of the first conical portion, a first 'Y'-shaped flow guide pipe is arranged in the crystallizer, extends out the top end of the crystallizer and is connected with material outlets of the first evaporator and the second evaporator through two second 'Y'-shaped flow guide pipes, a first rotational flow device and a second rotational flow device are sequentially connected on the outside of the first flow guide pipe below the wire mesh demister from top to bottom, so that the integrated forced circulation crystallizing evaporator for producing the large-grained ammonium sulfate is small in occupied area, and the layering effect of different crystal sizes is good.

Description

technical field [0001] The invention relates to the technical field of equipment for producing large-grain ammonium sulfate, in particular to an integrated forced circulation crystallization evaporator and a device for producing large-grain ammonium sulfate. Background technique [0002] At present, the evaporation and crystallization equipment used in the production of large-grain ammonium sulfate generally requires an evaporator and a crystallizer; since the evaporator and the crystallizer are separate devices, the required floor area is relatively large, and the crystallizer has a large impact on the feed liquid. Delamination of different grain sizes stays ineffective. Contents of the invention [0003] The purpose of the present invention is to provide an integrated forced circulation crystallization evaporator and device with small footprint and good stratification effect of different grain sizes to produce large grain ammonium sulfate. [0004] Technical scheme of t...
