Feeding pretreatment device for reaction kettle

Abstract

The invention provides a feeding pretreatment device for a reaction kettle. The feeding pretreatment device comprises a pretreatment storage tank and a pretreatment system. The pretreatment system comprises a spiral stirring pipeline, an outer layer is coated with a heating oil pipe, the bottom of the spiral stirring pipeline is provided with a discharging port, a spiral pipeline is arranged in the spiral stirring pipeline, the top of the spiral stirring pipeline is provided with an injection port, and the discharging port is vertically connected with the spiral stirring pipeline. The discharging port is connected with the pretreatment storage tank, an outer layer of the heating oil pipe is a heat insulation layer, and the bottom of the pretreatment storage tank is provided with a reaction kettle input pipe. A rotating device and a lifting device are arranged on the outer side of the heat insulation layer, and the rotating device comprises a fixed component and a rotating component. The feeding pretreatment device has the advantages that a function of staged mixing of various raw materials is increased, various functions such as premixing, preheating and pre-depressurization can be achieved, the industrialized flowline production requirements of raw material mixing and reaction can be achieved, and original process steps can be effectively reduced.

Description

technical field [0001] The invention belongs to the field of supporting equipment for reactors, in particular to a feed pretreatment device for reactors. Background technique [0002] Reactors are widely used in petroleum, chemical, rubber and other fields. They are pressure vessels used to complete vulcanization, nitration, hydrogenation, polymerization, condensation and other industrial processes. They can realize the heating, evaporation, cooling and low-speed mixing functions required by the industry. The reactor is a comprehensive reaction vessel, and the structure, function and configuration accessories of the reactor are designed according to the reaction conditions. From the beginning of the feed-reaction-discharge, the preset reaction steps can be completed with a high degree of automation, and the temperature, pressure, mechanical control (stirring, blasting, etc.), reactants / products during the reaction process Important parameters such as concentration are stric...
