Abstract
The invention discloses a multi-cycle vertical type drying method and device. According to the method, hot gas with carbon molecular sieve raw materials enters a vertical type drying pipeline, so that when the hot gas rises in the vertical type drying pipeline, the hot gas and the carbon molecular sieve raw materials are fully mixed in a contacting mode, and the carbon molecular sieve raw materials after preliminary drying are dried again. According to the method, a plurality of sections of expanding pipes are arranged on a pipe body of the vertical type drying pipeline, the hot gas with the carbon molecular sieve raw materials enters the expanding pipes, then the flow speed of the hot gas is suddenly decreased, when the hot gas with the carbon molecular sieve raw materials flows out of the expanding pipes, the flow speed is suddenly increased, during flow speed changing, the hot gas and the carbon molecular sieve raw materials are in full contact, and accordingly the carbon molecular sieve raw materials are better dried. According to the method, a heat exchanging layer is arranged in an environment-protecting energy-saving burning device, air enters the heat exchanging layer for heat exchanging, hot gas is formed, and then the hot gas enters the vertical type drying pipeline to dry the carbon molecular sieve raw materials.
