Description

Small moving bed reaction device

Technical Field

The utility model relates to the technical field of moving bed reactors, in particular to a small moving bed reaction device.

Background

The moving bed reactor is a reactor for realizing gas-solid phase reaction process or liquid-solid phase reaction process, granular or massive solid reactant or catalyst is continuously added at the top of the reactor, along with the progress of the reaction, solid materials gradually move downwards, finally, the solid materials are continuously discharged from the bottom, and fluid passes through a solid bed layer from bottom to top (or from top to bottom) to perform the reaction.

And in publication CN213913046U a moving bed reactor is mentioned, which is obtained by providing a gas inlet and a solid reactant outlet in the lower part of said moving bed reactor; a gas outlet and a solid reactant inlet are arranged at the upper part of the moving bed reactor; a rotary table capable of horizontally rotating is arranged in the moving bed reactor, and comprises a closed baffle plate, a ventilation baffle plate and a material distribution port; wherein the airtight separator blocks the passage of solid reactants and gases; the gas permeable barrier blocks the passage of solid reactants but allows the passage of gases; the distribution opening allows solid reactants to pass through, the turntable rotates during operation, the solid reactants on the turntable are in a relatively static state, the airtight partition plate and the breathable partition plate prevent the solid reactants from falling down, the solid reactants only flow down from the distribution opening, and the solid reactants uniformly fall onto the surface of the turntable at the next stage from the distribution opening due to the fact that the distribution opening rotates along with the turntable, so that uniform distribution is realized. The rotary table rotates at a constant speed, and the airtight partition plate cannot pass through gas, so that the gas can only move upwards from the breathable partition plate (the area of a distribution opening is generally small, and the permeated gas can be ignored), so that the flue gas in the tower can be guided, and the active coke in the tower can uniformly and completely contact and react with the flue gas, thereby avoiding dead angle areas. The moving bed reactor of the utility model divides active coke in the tower body into a plurality of step areas through the turntable, thereby realizing multistage series adsorption reaction. The flue gas communication of different step areas is realized through the breathable baffle on the turntable, and a series flue gas pipeline is not required to be additionally arranged, so that the construction occupation and the construction investment are reduced, certain defects still exist, the optimization is required, and the specific defects are as follows: the existing gas-permeable separator is easily blocked by impurities of gas in the completion of the reaction after the reaction for a long time, so that the efficiency of the whole reaction becomes low.

Therefore, it is important to design a small moving bed reaction device to improve the overall practicality by changing the technical defects.
