Problems solved by technology

Although these methods are effective, the effect is limited. The reason is that the heat and moisture exchange speed between the drying medium and the material of the existing drying equipment is not fast enough, and the temperature of the surface of the drying equipment and the exhaust gas cannot be lowered.

Abstract

The invention discloses a circulating fluidized bed pneumatic drying device with ultra-low energy consumption. According to the circulating fluidized bed pneumatic drying device, a circulating channel is formed by a draught fan (1), a circulating pipe I (2), a dust remover (4), an adjusting valve (5), an air inflow three-way joint (6) and a circulating pipeline II (7). Air flow is sucked from an air inlet of the air inflow three-way joint (6), under the action of the draught fan, materials and the air flow are mixed inside the circulating channel to form a fluidized state and flow circularly at high speed, water of the materials is rapidly vaporized in the flowing process, the heat absorption capacity is large during water vaporization, the wet air flow is exhausted from an exhaust port of the dust remover (4), and the temperature of the wet air flow is low; due to heat insulation materials wrapping the circulating pipe, heat losses are reduced, and drying energy consumption is low.

Description

technical field [0001] The invention relates to an airflow drying equipment for granular materials and powder materials. Background technique [0002] Drying equipment is a high-energy-consuming equipment. Reducing the energy consumption of drying equipment is of great significance to energy saving, emission reduction and clean production. The methods usually used for drying and energy saving are: (1) reduce the heat loss in the drying process; (2) reduce the evaporation load of the dryer; (3) increase the air temperature at the inlet of the dryer and reduce the temperature of the exhaust gas at the outlet; (4) part of the exhaust gas Recycling. Although these methods are effective, the effect is limited. The reason is that the heat and moisture exchange speed between the drying medium and the material of the existing drying equipment is not fast enough, and the temperature of the surface of the drying equipment and the exhaust gas cannot be lowered. Drying has great poten...
