Description

Technical Field

[0001] The invention relates to the technical field of chemical industry, in particular to a crystallization device which is easy to clean. Background Art

[0002] Crystallization equipment, as one of the core equipment in the field of chemical engineering and materials science, has a long history of background technology and is constantly innovating. It is based on the principle that solutes in a solution can spontaneously form crystals under specific conditions. Through a series of precisely designed processes and devices, the material transformation process from liquid to solid is realized. This technology is not only widely used in the purification and preparation of chemical products, such as drug crystallization in the pharmaceutical industry, sugar and salt crystallization in the food industry, but also plays an important role in water treatment and heavy metal recovery in the field of environmental protection. The research and development and improvement of crystallization equipment are always accompanied by in-depth research on solution thermodynamics, kinetics and crystal growth mechanism. From the early simple cooling crystallization tank to the modern continuous crystallizer, vacuum crystallizer, and intelligent crystallization system combining efficient heat exchange technology and advanced automatic control system, each technological innovation has greatly improved the crystallization efficiency, reduced energy consumption, and improved the purity and quality of the product. In particular, in recent years, with the introduction of computer simulation technology and artificial intelligence algorithms, the design and optimization of the crystallization process have become more accurate and efficient, enabling crystallization equipment to better adapt to different material properties and production needs. In addition, the enhancement of environmental awareness has also promoted the development of crystallization equipment in a greener and more sustainable direction. For example, by optimizing the crystallization process, reducing the emission of wastewater and waste gas, and developing crystallization technology that can recycle by-products, not only the negative impact on the environment is reduced, but also the efficiency of resource utilization is improved.

[0003] During the crystallization process of the crystallizer, a layer of crystals will gradually appear on its inner wall. The accumulation of these crystals will not only reduce the heat transfer efficiency of the crystallizer, but may also cause physical damage to its structure, thus affecting the overall performance of the crystallizer and the quality of the crystallized product. Therefore, it is necessary to clean and maintain it in time. Summary of the invention

[0004] The invention aims to solve the technical problem of how to clean the crystals on the inner wall of the crystallizer, and proposes a crystallization device that is easy to clean. The technical solution of the invention is as follows: A crystallization device that is easy to clean includes: a base, an evaporation crystallization device, a cleaning device, a waste gas recovery device, and a controller.

An electric control valve is arranged in the discharge pipe, and the electric control valve is electrically connected to the controller.

[0006] When the circulating water pump is working, the circulating water pump inputs the hot water in the hot water tank into the heat conduction pipe.
