Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of the isolation kettle, and particularly relates to a freezing condensing device of an isolation kettle. BACKGROUND

[0002] In the production process of chemical industry, pharmacy and fine chemical industry, isolation reaction is usually carried out in a sealed reaction kettle (hereinafter referred to as "isolation kettle"). During the isolation reaction process, the temperature in the kettle rises due to the heat generated by the reaction. In order to ensure the product quality and the stability of the reaction, the temperature in the kettle needs to be effectively controlled. The traditional cooling method of the isolation kettle relies on fixed cooling devices (such as cooling coils, jackets or heat exchangers) arranged at certain positions on the kettle wall or in the kettle, and the cooling is achieved by continuously injecting cooling water or other cooling media into the devices. However, such devices have the following problems and deficiencies:

[0003] 1. Limitation of cooling efficiency: In conventional design, the cooling elements are usually fixed at a specific height. If the liquid level in the kettle changes or the state of the material changes, the fixed position of the cooling element cannot be dynamically adjusted with the change of the liquid level of the material, and it does not completely match the actual temperature demand of the reaction area in the kettle. This will result in unnecessary consumption of cooling medium when the liquid level is low, and precise temperature control cannot be achieved.

[0004] 2. High energy consumption and cooling agent consumption: The traditional cooling system often needs to continuously inject cooling water during operation, even when the reaction is in the later stage or the liquid level is low. Since the effective section of the cooling coil cannot be adjusted in real time according to the liquid level and temperature demand, the overall system is prone to overcooling, resulting in waste of cooling agent and increase of energy consumption.

[0005] 3. Lack of flexible adjustment mechanism: The existing isolation kettle often lacks a simple mechanism that can dynamically adjust the height of the cooling coil or heat exchange element. When the effective working section of the cooling part cannot be flexibly changed according to the reaction progress and the change of the liquid level, the operator can only reduce the energy consumption and material consumption by intermittently adjusting the cooling agent flow or the stirring rate in the kettle, but the adjustment precision and response speed are insufficient.
