Abstract

The invention discloses a hot-air drying machine capable of utilizing waste heat and achieving penetrating countercurrent fluidization. The upper portion of a drying tower is connected with an induced draft fan, and the induced draft fan is connected with a cyclone dust removing waste heat efficient recoverer formed by a tube-type heat exchanger and a cyclone dust collector in an overlapped manner in the tangent direction and then is emptied; the air inlet end of the shell side of the tube-type heat exchanger is communicated with the atmosphere, and the air outlet end of the shell side of the tube-type heat exchanger is connected with the lower portion of the drying tower through an air blower and a steam finned heater; and an impeller of the induced draft fan is of a structure that blades are in a hollow and wedged shape, and the contour line of the appearance of the induced draft fan is an involute. According to the hot-air drying machine capable of utilizing the waste heat and achieving the penetrating countercurrent fluidization, creative integration is conducted on waste heat utilization and dust removal, the cyclone dust removing waste heat efficient recoverer is designed out, the equipment input is reduced, and the work efficiency is improved; and due to the fact that sieve mesh cone covers, sieve mesh cone discs, discharging tubes, a stretching vibration transmission shaft and conical plugs are arranged, penetrating, countercurrent, boiling and fluidization drying of materials are exquisitely and perfectly achieved, more energy is saved, the drying quality is higher, the power consumption of the induced draft fan is lower, and the application prospect is wider.

Description

technical field [0001] The invention relates to a drying machine, which specifically refers to a hot air type penetrating countercurrent fluidization drying machine which utilizes the tail heat of a fan without dust accumulation. 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 airflo...
