Carbon-gas separation device for process of powdery activated carbon regeneration

Abstract

The invention discloses a carbon-gas separation device for a process of powdery activated carbon regeneration. The device utilizes a high-temperature sintering-resistant metal powdery filter to prepare a blade of a spiral conveying shaft, according to sizes of powdery activated carbon particles, the filtering number of the sintered metal powder filter is set, the blade of the spiral conveying shaft is used as a filtering interface, cracking gas generated in the regeneration process is used as a pressure source, pressure difference is generated at the filtering interface so that cracking gas passes through the filtering interface to a hollow cavity of the spiral shaft under self-pressure and then is discharged through one end of the hollow cavity, and carbon powder is intercepted in a heating pipe and is sequentially heated until the regeneration is completed and the regenerated carbon powder is pushed out of a regeneration zone. The carbon gas separation device fills a blank of carbon-gas separation in the process of powdery activated carbon regeneration so that the efficiency of each component is maximized, the best use of materials is realized, redundant equipment is avoided, anextra space and extra energy are avoided and the lowest raw material loss is achieved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to a carbon gas separation device, in particular to an online carbon gas separation device used in the regeneration process of powdered activated carbon. Background technique [0002] As a widely used adsorbent, activated carbon has a considerable annual usage in various industries. The use of activated carbon has strong economic and environmental benefits, and is supported and encouraged by national policies. [0003] In the current field of powdered activated carbon regeneration, the usual process is to heat the carbon powder to a high temperature above 800 degrees. Under this condition, the adsorbed substance is decomposed into gas and released, restoring the adsorption performance of activated carbon and realizing regeneration. During the release of cracked gas, since the particles of powdered activated carbon are very small, it is easy to drift with the air flow. ...

Problems solved by technology

This technology is very cumbersome, with many process links and process equipment, and because most of the final links are filtered by bag dust removal, there is still a very small amount of carbon powder leakage

On the other hand, water cooling is mostly used in the cooling process. The heat energy taken away by the water is not used, and additional equipment and energy are needed to circulate and cool the water heated during the cooling process. In short, the old technology can not reuse the heat energy, It also consumes heat energy, which consumes too much energy
