Description

An evaporator with overflow protection structure Technical Field

[0001] This utility model relates to the field of evaporator technology, specifically to an evaporator with an overflow protection structure. Background Technology

[0002] An evaporator is a heat exchange device that uses heat to vaporize a solvent (usually water) in a liquid, thereby concentrating the solution or recovering the solvent. Its core principle is to use thermal energy to convert liquid into vapor while retaining or separating the solute. It is widely used in industries such as chemical, food, pharmaceutical, and environmental protection. Evaporators typically consist of a heating chamber, a separation chamber, and a condenser. Depending on process requirements, they can employ technologies such as multi-effect evaporation, mechanical vapor recompression (MVR), or falling film evaporation, featuring high efficiency, energy saving, and a high degree of automation. Specially designed evaporators (such as those with overflow protection structures) can also handle issues such as foaming and liquid level fluctuations, ensuring stable operation.

[0003] The prior art patent application number (202321188516.4) entitled "An Evaporator with an Overflow Device" includes a separator body, an overflow tank body, and a cleaning structure. The overflow tank body is connected to the overflow port at the top of the separator body via an overflow pipe. The cleaning structure is arranged inside the overflow tank body. The rotating part of the cleaning structure is rotatably mounted on the overflow tank body. The unblocking part of the cleaning structure is driven by the rotating part to act on the discharge port of the overflow tank body. This invention has the advantage of allowing suspended solids, high-boiling-point organic matter, and oily substances floating on the top of the liquid in the separator body to overflow into the overflow tank body and then be discharged. However, during the operation of the separator, suspended solids... Impurities such as floating matter, high-boiling-point organic matter, and oily substances will enter the overflow tank with the overflow. These viscous substances easily adhere to the inner wall of the connecting pipe between the separator and the overflow tank. As the equipment operates for a long time, the deposits on the pipe wall will gradually accumulate and thicken, eventually causing the flow cross-section of the connecting pipe to shrink or even completely block it, which seriously affects the normal operation of the system. In addition, the existing discharge port cleaning mechanism has obvious shortcomings. It relies on manual operation, which is not only inefficient but also makes it difficult to remove the deposited impurities attached to the discharge port in a timely manner. This lack of automation can easily cause impurities to accumulate and harden, which increases the difficulty of subsequent cleaning and may also cause abnormal equipment operation. To address this, we propose an evaporator with an overflow protection structure. Summary of the Invention

[0004] The purpose of this utility model is to provide an evaporator with an overflow protection structure to solve the problem mentioned in the background art, where viscous substances easily adhere to the inner wall of the connecting pipe between the separator and the overflow tank during operation. The deposits on the pipe wall gradually accumulate and thicken, eventually leading to a reduction in the flow cross-section of the connecting pipe or even complete blockage, which seriously affects the normal operation of the system. The design of the discharge port cleaning mechanism has obvious deficiencies, relying on manual operation, which is not only inefficient but also makes it difficult to remove the deposited impurities adhering to the discharge port in a timely manner.
