Rotary type continuous feed fixed bed reactor

Abstract

The invention relates to a rotary type continuous feed fixed bed reactor, which belongs to the technical field of a catalytic fixed bed reactor, and comprises four reaction kettles, four trays, a rotary disc and a moveable sealing joint, air inlet pipes and air outlet pipes connected respectively with air inlets and air outlets of the reaction kettles, and a power transmission mechanism. The four reaction kettles are symmetrically fixed on the rotary disc through the four trays respectively. The air inlet and the air outlet of each reaction kettle are connected with corresponding air inlet pipe and air outlet pipe at stations I-IV respectively through the moveable sealing joint. A motor output shaft is connected with a rotary disc shaft. The air inlet pipe of the reaction kettle is in butt joint with the air inlet of the reaction kettle in station I and sleeved with a heat exchange sleeve. The air inlet of the heat exchange sleeve is connected with the air outlet of the reaction kettle at a replacement station III and the air outlet is communicated with atmosphere. The rotary type continuous feed fixed bed reactor maintains stable production and large throughput of the fixed bed reactor and overcomes the deficiency that current fixed bed reactor fails to produce continuously, thereby realizing efficient, energy-saving, continuous, stable and large-scale production.

Description

technical field [0001] The invention relates to a rotary continuous feed fixed-bed reactor, which belongs to the technical field of catalytic fixed-bed reactors. technical background [0002] Fixed bed reactor, also known as packed bed reactor, is a reactor filled with solid catalyst or solid reactant to realize heterogeneous reaction process. The solids are usually in granular form, with a particle size of about 2 to 15 mm, and are piled up into a bed of a certain height (or thickness). The bed is stationary and the fluid passes through the bed to react. The difference between it and the fluidized bed reactor and moving bed reactor is that the solid particles are in a static state. Fixed bed reactors are mainly used to realize gas-solid phase catalytic reactions. When used in gas-solid or liquid-solid non-catalytic reactions, the bed is filled with solid reactants. [0003] There are three basic types of fixed bed reactors: (1) Axial adiabatic fixed bed reactors. The f...

However, the fixed bed reactor also has its fatal shortcomings, that is, the catalyst cannot be replaced during the operation, and the reaction that requires frequent regeneration of the catalyst is generally not suitable for use.
