Problems solved by technology

[0004] However, since the return pipe of the crystallization tank continues to flow through the mother liquor, it is easy to crystallize in the return pipe and cause the blockage of the return pipe, so that the return flow of the mother liquor becomes smaller, resulting in an increase in the liquid level of the crystallization tank and the emergence of the tank
[0005] In view of the above problems, it is necessary to develop an anti-clogging crystallization device to solve the problem that the liquid level of the crystallization tank rises and the tank leaks due to the blockage of the return pipe

Abstract

The invention discloses an anti-blocking crystallization device, and relates to the technical field of ammonium sulfate production equipment. The crystallization device comprises a communicating pipe and two crystallization tanks. The side wall of the crystallization tank is connected with a liquid inlet pipe and a return pipe, the crystallization tank is provided with a flushing pipe, and the flushing pipe is inserted into the crystallization tank and partially extends into the return pipe; and the two ends of the communicating pipe are respectively communicated with one crystallization tank. The crystallization device can keep the backflow pipe smooth and prevent the liquid level of the crystallization tank from rising and overflowing.

Description

technical field [0001] The invention relates to the technical field of ammonium sulfate production equipment, in particular to an anti-clogging crystallization device. Background technique [0002] Ammonium sulfate is an inorganic substance that is mainly used as a fertilizer for various soils and crops. It can also be used in textile, leather, medicine and other aspects. The current industrial method for preparing ammonium sulfate is the crystallization method, which mainly consists of several stages of reaction, formation of supersaturated mother liquor, generation of crystal nuclei and growth of crystals. [0003] In the crystallization process, no matter the formation of crystal nuclei or the growth of crystal nuclei, the solute in the mother liquor must be consumed, and a certain degree of supersaturation is used as the driving force. Therefore, the mother liquor needs to be continuously introduced into the crystallization tank during the reaction process. To maintain...
