Material drying system

Abstract

The invention discloses a material drying system, comprising a drying tower, a fluidized bed and a cyclone separating tower; wherein a wind inlet is arranged at the upper end of the drying tower and is connected with a fan through a pipeline; a wind exhaust is arranged at the side of the drying tower and is connected with the cyclone separating tower through a wind exhaust pipeline; a discharge hole is arranged at the lower end of the drying tower and is connected with the fluidized bed through the pipeline; at least two wind inlets are arranged at the lower end of the fluidized bed; the wind outlet arranged at the upper end of the fluidized bed is connected with the wind exhaust pipeline of the drying tower through the wind outlet pipeline and then is connected with the cyclone separating tower; the top end of the cyclone separating tower is configured into an air outlet; the diameter of the cyclone separating tower is 3270mm; one cyclone separating tower is added to the material drying system, the diameter of the cyclone separating tower is increased to 3270mm from initial 400mm, the spiral length is increased, therefore, the unit volume is increased, the separating effect is improved, and the amount of the grain materials in the exhausted wind is decreased. In this way, the environment pollution is decreased to minimal.

Description

technical field [0001] The invention relates to a material drying system. Background technique [0002] At present, for many materials, in order to facilitate storage and transportation, etc., the materials are often dried. Generally, the materials are first poured into the drying tower for drying, and then the fluidized bed is used for further drying. The fluidized bed is a secondary drying and cooling device developed in the 1960s. It is widely used in the chemical industry, light industry, medicine, food and building materials industries. There are bag type and cyclone type in domestic fluidized bed exhaust and dust removal. And cyclone dust recovery is the main method. However, using the cyclone-type recovery dust as the dust removal and recovery equipment for the fluidized bed, it was found that the dust could not be completely removed during use. A large amount of dust could be seen from the air outlet outside the wall, which polluted the environment, and the dust was...

Problems solved by technology

[0003] The purpose of the present invention is to address the above problems and provide a material drying system to solve the problem that the traditional material drying system has poor dust separation effect, causes environmental pollution, and the dust cannot be recycled and reused, which wastes resources.
