REFINING REACTOR

TECHNICAL FIELD

The present invention relates to the technical field of chem- ical plants and in particular to a refining reactor.

BACKGROUND ART

A reaction kettle is a comprehensive reaction vessel. The structure design and parameter configuration of the reaction ket- tles are carried out according to the requirements of different processing conditions. Preset reaction steps can be completed with a high degree of automation in feed-reaction-discharge process, and important parameters such as temperature, pressure, mechanical control (ultrasonic, microwave, shear, stirring, blowing, etc.), reactant /product concentration and so on in the reaction process can be strictly regulated. A conventional reaction kettle is gen- erally composed of a kettle body, a stirring device, a heating de- vice, a cooling device and a sealing device, and the corresponding supporting auxiliary equipment includes a fractionation column, a condenser, a water separator, a collection tank, a vacuum pump and a filter, etc. However, for some heterogeneous chemical reactions, such as solid-liquid heterogeneous chemical reactions, since chem- ical reagent in reaction liquid can only contact a surface of sol- id particles, it is difficult to enter an interior of the solid particles, a contact area between the reaction liquid and the sol- id particles is limited, collision probability of reaction mole- cules is low, chemical reaction only occurs on the surface of the solid particles, and the reaction rate and reaction efficiency are low. In particular, vulcanized rubber powder and fresh and wet aquatic and/or terrestrial plants, which are not easily pulverized into fine powder, have slow desulfurization regeneration and chem- ical degradation reactions. Only when the solid particles are con- tinuously crushed in the reaction process or the surface of the solid particles in contact with the reaction liquid is refreshed under the action of high shear force, the contact area of chemical reaction can be increased and the reaction speed can be improved.

High shear forces, in turn, can provide a driving force for the degradation of macromolecules.

The rubber powder particles are continuously subjected to a high shear force. The rubber powder particles are continuously deformed. A surface of the rubber powder is continuously refurbished. The degradable cross-linking bonds wrapped inside are exposed to the surface, and the desulfurization degradation chemical agent can completely col- lide with the degradable cross-linking bonds in the vulcanized rubber network structure without difficult penetration, thereby breaking the degradable cross-linking bonds. The high shear force generated by the high-speed and relatively rotating abrasive discs on the rubber powder strongly promotes the breaking degradation of the chemical bonds of the cross-linking points in the vulcanized rubber network structure, thus greatly improving the desulfuriza- tion degradation reaction speed and desulfurization effect.
