AI Technical Summary

Technical Problem

In the preparation of carbon materials, existing fixed beds have problems such as high temperature and long use time, difficulty in separation of carbon source mixing, waste of high-temperature exhaust gas emissions, and uneven production quality. It is difficult to achieve energy-saving, environmentally friendly, high-yield and high-quality cyclic preparation.

Method used

Using a circulating fixed bed, including a temperature control body, a temperature control section reactor and a controller, cyclic production is realized through the relative movement of the AB tube, and the residual temperature of the exhaust gas is used to assist heating to achieve secondary utilization of energy, and the A tube is driven by the rotating body Rotate relative to tube B to control the incoming and outgoing materials to achieve full reaction and uniform heat and mass transfer.

Benefits of technology

The production cycle is shortened, the output and the quality of carbon materials are improved, the efficient use of energy and environmental protection are achieved, and the reliability and industrialization problems of the fixed bed are solved.

Abstract

The invention discloses a circulating fixed bed. The circulating fixed bed is used for circularly producing a carbon material and comprises a temperature control body, at least one temperature control section reactor and a controller, the reactor is at least partially located in the temperature control body, and the temperature control body controls the temperature of each temperature control section reactor; the reactor comprises a rotating body and pipes AB, the pipes AB comprise a pipe A and a pipe B, and the pipe A and the pipe B are arranged in a sleeving mode and move relatively; and the controller controls materials to enter the A pipe and the B pipe to react to generate a carbon material, the controller controls the rotating body to rotate to drive the A pipe to rotate relative to the B pipe so as to feed and discharge the material, and the A pipe forms different angles relative to the B pipe in cycles so as to achieve cyclic production of the carbon material. The problems of energy conservation, environmental protection, high yield and homogenization in the prior art can be solved.
