Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of sugar alcohol preparation equipment, and specifically relates to a gas-liquid separation device for a sugar boiling tank. Background Technology
[0002] The sugar boiling tank is a high-efficiency single-effect evaporator widely used in the sugar and sugar alcohol industries. Its working principle involves heating the material by introducing steam into the bottom tubes, and using a stirring device to force the solution to circulate between the heated tubes, increasing heat exchange efficiency. Simultaneously, a vacuum device removes the evaporated water vapor, and the lower boiling point of the solution under vacuum facilitates evaporation and concentration, resulting in significantly better energy efficiency than traditional single-effect evaporators. In actual production, some sugar solutions may foam during evaporation in the sugar boiling tank. Currently, domestic gas-liquid separation devices are more commonly used in the petroleum industry for static gas-liquid separation. These typically employ methods such as gravity sedimentation and centrifugal separation, primarily utilizing the difference in specific gravity and density between liquids and gases. Directly applying static gas-liquid separation devices cannot effectively remove sugar solution foam, and there is still a risk of sugar leaking into the vacuum tubes and even the vacuum system, causing blockages or damage to the equipment. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a gas-liquid separation device for a sugar boiling tank to prevent sugar runoff caused by foaming during the sugar boiling process.
[0004] This utility model is implemented as follows: a gas-liquid separation device for a sugar boiling tank is provided, including a gas-liquid separator. The gas-liquid separator is installed at a position higher than that of the sugar boiling tank. A defoaming stirrer is installed inside the gas-liquid separator. An air pipe interface, a return liquid pipe interface, and a vacuum pipe interface are also respectively installed on the gas-liquid separator. The air pipe interface is connected to the exhaust port of the sugar boiling tank through an air extraction pipe. The return liquid pipe interface is connected to the return liquid port of the sugar boiling tank through a return liquid pipe. The position of the return liquid port is lower than the liquid level of the sugar liquid in the sugar boiling tank. The vacuum pipe interface is connected to a vacuum system through a vacuum pipe.
