Automatic control method and device for adding activated carbon in production of anhydrous glucose

Abstract

The invention belongs to the technical field of the production of anhydrous glucose and particularly relates to an automatic control method and device for adding activated carbon in the production of anhydrous glucose. The device of the invention contains a carbon powder tank, a carbon-preparing tank, a carbon-storing tank and a decoloring tank, wherein the side walls of the carbon-storing tank and the carbon-preparing tank are provided with liquid level sensors; and an electrically operated valve, a mixer, a negative pressure pump, a pump I, a pump II, the liquid level sensors and a flowmeter are connected with an on-site controller. By using the carbon-preparing tank and the carbon-storing tank commonly, the pollution to the external environment can be avoided and the flowmeter can be used to accurately measure the amount of carbon slurry. Therefore, a defined amount of activated carbon is in the decoloring link, the conditions that insufficient activated carbon is added to influence the product quality and excess activated carbon is added to lead to waste can be avoided, and the stability and uniformity of the control of intermediate product can be further ensured.

Description

technical field [0001] The invention belongs to the technical field of anhydrous glucose production, in particular to an automatic control method and equipment for adding activated carbon in anhydrous glucose production. Background technique [0002] Activated carbon can use almost any carbon-containing substance as a raw material, and activated carbon has adsorption. What is directly related to the adsorption capacity of activated carbon is the oxide complex performance on its surface. The simplest complex can be considered as carbon monoxide and carbon dioxide complex. The acidic oxides impart polar properties to activated carbon and thus tend to adsorb more polar compounds. The metal ion sites on the surface of activated carbon are positively charged and have the ability to adsorb molecules with excess electron sites. Effectively adsorb pigment molecules and some inorganic ions. To achieve the purpose of decolorization in the production process of anhydrous glucose. ...

AI Technical Summary

Problems solved by technology

The conventional carbon adding device adopts the method of adding manually or filling material through a funnel, and conveying with an auger. The disadvantage of this method is that it is easy to cause pollution to the surrounding environment when adding activated carbon, and it cannot be accurately measured.
