Detailed Description
It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The invention is explained in more detail below with reference to the figures and examples:
as shown in figure 1, the method for accelerating the outward migration of water vapor in a biomass stack is characterized in that a plurality of ventilation air passages 2 are arranged in the stack 1; a ventilation pipe 3 is placed into the ventilation air flue 2, the ventilation pipe 3 is positioned in the material stack 1, one end of the ventilation pipe 3 is opened and positioned at the upper section of the ventilation air flue 2, the other end of the ventilation pipe 3 is connected with a wind power device 4, and the wind power device 4 is a fan; pumping out the ventilation pipe to pump out the water vapor in the ventilation air passage; after the stack fuel moisture has been reduced to a predetermined level, the stack is removed by removing the vent and removing the fuel. Because there are a large amount of microorganisms in the living beings stack, the aerobic activity of these microorganisms produces a large amount of heats in the stack, and the ventilation air flue is located inside the living beings stack, and the heat is piled up in a large amount in the ventilation air flue, bleeds to the ventilation pipe, can discharge the steam in the ventilation air flue, realizes the drying of living beings stack.
