The structure of the system comprises a fluidized bed granulator, a fluidized bed drying cooler, a crystal seed circulating system, a dust reclaiming system and an air supply dehumidifying system, wherein the crystal seed circulating system comprises a vibrating screen and a crusher; the dust reclaiming system comprises a fluidized bed granulator dust reclaiming system and a fluidized bed drying cooler dust reclaiming system; the fluidized bed granulator dust reclaiming system is connected with a fluidized bed granulator; the fluidized bed drying cooler dust reclaiming system is connected with a fluidized bed drying cooler; the air supply dehumidifying system comprises a fluidized bed granulator heat supply system and a fluidized bed drying cooler heat supply dehumidifying system; the fluidized bed granulator heat supply system is connected with the fluidized bed granulator; and the fluidized bed drying cooler heat supply dehumidifying system is connected with the fluidized bed drying cooler. The system has the characteristics of no existence of high-temperature carbonization and decomposition problems, good product quality, no environmental pollution from tail gas and the like.

Description

technical field [0001] The invention relates to a low-temperature granulation and drying production system of a fluidized bed, in particular to a low-temperature granulation and drying production system of a fluidized bed of monosodium glutamate waste liquid. Background technique [0002] Monosodium glutamate waste liquid, also known as glutamic acid fermentation waste liquid, is an organic waste liquid by-product in the glutamic acid refining process. It is the main source of pollution in monosodium glutamate factories. Due to the difficulty of treatment, it has always been the main technology that plagues the development of monosodium glutamate industry. With the increasing requirements of environmental protection, it has even become a key issue related to the survival of enterprises. [0003] my country's MSG industry has carried out the treatment of MSG waste liquid earlier, and has done a lot of research and development work, and proposed a variety of treatment solution...

Problems solved by technology

[0012] CN101884847A discloses a drying method for treating glutamic acid fermentation waste liquid by using a spray dryer. Small-scale production tests have been carried out in individual monosodium glutamate production enterprises. Because the organic components in the glutamic acid fermentation liquid are complex, the softening point of the powder obtained by drying Low moisture absorption, strong moisture absorption, resulting in difficulty in discharging materials from the spray dryer, poor continuity and stability, low production capacity, and high operating costs, and powder products have strong moisture absorption, small bulk specific gravity, and easy agglomeration, making it difficult for downstream users use

[0013] Currently, there is no good solution
