Multi-effect hot air drying tower

Abstract

The invention discloses a multi-efficiency hot air drying tower which consists of a preheating bin, a drying bin, a cooling bin, a heat exchange and dissipation device, a discharging valve, a circulating flow ventilation and exhaust device, a parallel flow and counter flow circulating ventilation device, a condensing and heat dissipating device, an exhaust pipe, a draining pipe, a heat conduction pipe, a feed opening, a discharge opening and a support; air outside the multi-efficiency hot air drying tower sequentially enters into the cooling bin, the drying bin and the preheating bin, and is finally exhausted out of the tower by a fan in the preheating bin; the heat exchange and dissipation device directly performs heating, heat conduction and heat dissipation on materials and air in the drying tower; after hot air and moisture in the bin are condensed by the condensing and heat dissipating device, heat energy released by condensation can be used for multiple times; hot air quickly forms convection by the pressure of a wind force of the fan through ventilation and exhaust of the circulating flow ventilation and exhaust device and the parallel flow and counter flow circulating ventilation device; the materials are dried by hot air convection, so that the processing cost is greatly reduced; due to controllable temperature, the quality of the materials is ensured; the multi-efficiency hot air drying tower realizes green drying with energy conservation and emission reduction effects.

Description

technical field [0001] The invention relates to a drying tower for drying materials, in particular to a multi-effect hot air drying tower. Background technique [0002] At present, the drying towers used for drying materials on the market all use high temperature and strong wind drying. The hot air drying process is to dry materials with downstream, countercurrent, forward and countercurrent and combined hot air. The entire drying process is high-pressure drying in the tower. , there are problems such as the large volume of the drying equipment, the heat conversion of the hot air is completed outside the tower, the heat conversion rate is low, and the heat energy consumption is large; the heat energy in the discharged moisture and hot air cannot be utilized. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the existing hot air drying equipment technology, and provide a drying in the tower. The heat exchange and heat...
