Description

Gluconate solution activated carbon treatment device and method Technical Field The application relates to the technical field of gluconate production equipment, in particular to a gluconate solution activated carbon treatment device and method. Background The gluconate is very abundant in use and is widely applied to the fields of medicine, food, chemical industry, light industry, agriculture and the like as a polyhydroxy hydroxy acid salt. The types of gluconate are various, and each gluconate has different physical and chemical properties, and the selection and effect of the gluconate are different for different use occasions. The production of gluconate has a scale at present, so that the requirements of social life and production are greatly met, and an important material basis is provided for the production and development of society. Glucose peroxidase and catalase are added after glucose and calcium carbonate are mixed uniformly, and the calcium gluconate is directly obtained through 37-degree oxidation. The traditional mode has low labor productivity, high energy consumption and unstable product quality. The production modes of gluconate are various, and mainly include a catalytic air oxidation method, an electrochemical oxidation method, a metal catalysis method, a chemical oxidation method, a biological fermentation method, an enzyme method and the like, and pure gluconate can be formed for use only by neutralization, decolorization, concentration, approaching, centrifugation, dry impurity and other steps of the formed gluconate stock solution after oxidation. The decoloring step is an indispensable procedure for producing gluconate, and is mainly to adsorb pigments and small molecular substances existing in the solution. At present, active carbon decolorization is mainly adopted, and in the active carbon decolorization process, the active carbon needs to be ensured to be uniformly dispersed in a solution in a sufficient quantity so as to realize an efficient decolorization effect. Most of the current decolorizing devices simply calculate the required amount of the activated carbon, then continuously send the solution and the activated carbon into a mixer for mixing under the condition of ensuring the temperature, and in such a way, the uniform and sufficient mixing of the activated carbon in the solution cannot be completely ensured, especially, the flow rate of the solution can be changed due to the adjustment of the yield in the continuous production process, and the content of the activated carbon in unit volume and the uniform distribution of the activated carbon in the solution cannot be ensured by simply infusing the solution and the activated carbon into the mixer. Therefore, designing a gluconate solution activated carbon treatment device and method, which can adjust the mixing of activated carbon according to the flow of gluconate in real time, ensures that the activated carbon is uniformly mixed in the gluconate solution to improve the decoloring effect is the problem to be solved urgently at present. Disclosure of Invention The embodiment of the application also aims to provide a gluconate solution activated carbon treatment method, which comprises the steps of firstly determining the required activated carbon amount according to production information, obtaining the relation between the adding pressure and the discharging value of activated carbon from an adding mechanism under the action of pressure when the activated carbon is added according to the design data of equipment, further determining the amount of the activated carbon actually required to be added according to the flow of the gluconate solution detected in real time, determining the air pressure according to the relation between the discharging value of the activated carbon and the adding air pressure, accurately adjusting the adding air pressure, and ensuring that the adding amount of the activated carbon meets the decoloring requirement of the gluconate solution in real time. Meanwhile, the addition amount of the activated carbon can be determined to realize real-time automatic adjustment, so that the automatic operation is realized while the decoloring effect is ensured, and the efficiency of the decoloring process is greatly improved. The embodiment of the application aims to provide a gluconate solution activated carbon treatment device, which is characterized in that an activated carbon adding mechanism is arranged in an airflow cavity, and the adding amount of activated carbon in unit time is regulated according to the real-time detection of the flow of a gluconate solution in a liquid flow cavity, so that the uneven content of activated carbon in unit volume caused by adding the constant flow of the activated carbon without considering the flow of the gluconate solution is effectively avoided, insufficient decolorization of the activated carbon is further caused, and the decolorization effect of a decolorization
