Description

Circulating cooling device for glycine production Technical Field The embodiment of the disclosure relates to the technical field of glutamic acid production related equipment, in particular to a circulating cooling device for glycine production. Background In the glycine production process, temperature control is a key factor for ensuring smooth production and improving product quality and yield. The circulating cooling device for glycine production takes care of maintaining the stable temperature inside the reactor, and creates an optimal temperature environment for chemical reaction through circulating cooling medium. The method can ensure the efficient reaction, improve the quality and yield of the product, effectively avoid the problem of out-of-control reaction caused by abnormal temperature, prevent the quality of the product from being reduced and the like, and occupy an indispensable position in glycine production. However, the conventional circulation cooling device has a plurality of problems to be solved. Firstly, the heat absorption and cooling performance is poor, and the rapid cooling is difficult to realize. During some critical stages of glycine production, the reaction releases a large amount of heat, at which point a cooling device is required to rapidly remove the heat to maintain a stable temperature. However, the existing device cannot respond in time, so that the temperature fluctuation in the reactor is caused, the reaction process is influenced, and the quality and yield of the product are reduced. Secondly, the existing device has low energy utilization efficiency and serious energy waste phenomenon. In order to achieve the aim of cooling, the device often consumes a large amount of energy, but cannot fully exert the cooling effect, which clearly increases the production cost and runs counter to the currently advocated energy-saving and emission-reducing concept.
