Abstract

The invention discloses a tail heat recovery hot wind type penetration countercurrent fluidized dryer. The upper part of a drying tower is connected with an induced draft fan; the induced draft fan is tangentially connected with a cyclone dust removal tail heat efficient recoverer formed by superposing a shell and tube heat exchanger and a cyclone dust remover for evacuation; a shell pass intake end of the shell and tube heat exchanger is communicated with atmosphere, and an exhaust end is connected with the lower part of the drying tower by an air blower and a steam fin heater; an impeller of the induced draft fan has a structure with hollow reverse water drop-shaped blades and a disc-shaped back plate; and the outline of the induced draft fan is an involute. The cyclone dust removal tail heat efficient recoverer is designed through creatively integrating the tail heat recovery with the dust removal, so that the equipment investment is reduced, and the working efficiency is improved; and as a screen hole conical cover, a screen hole conical disc, a blanking pipe, an extension vibration transmission shaft and a conical plug are arranged, the penetration, the backflow, the boiling and the fluidized drying of materials are skillfully and perfectly realized, more energies are saved, the drying quality is higher, the fan power consumption is lower, and the application prospect is broader.

Description

technical field [0001] The invention relates to a drying machine, in particular to a tail heat recovery hot air penetrating countercurrent fluidization drying machine in which a fan does not accumulate dust. Background technique [0002] Due to its mature technology, strong adaptability, low operating cost and strong reliability, the hot air dryer is still one of the main preferred equipment for drying materials. , and the effective recovery of tail heat is of special significance for improving drying efficiency and realizing energy saving and emission reduction. [0003] The induced draft fan is the key equipment of the hot air dryer. The induced draft fan is generally a centrifugal fan. The continuous, stable and reliable operation of the induced draft fan is very important for the dehumidification of the dryer. Because most of the occasions where the dryer is used contain a certain amount of dust, the induced When the fan is working, when the airflow passes through the h...
