Non-uniform air distribution interconnected fluidized bed drying device

Abstract

The invention discloses a non-uniform air distribution interconnected fluidized bed drying device which comprises a separation section, a fluidization section, an air distribution section, built-in heat exchangers and partition plate heat exchangers. The separation section comprises a feeding port and an air outlet. The air distribution section comprises an air inlet, a partition plate and an air distribution plate. The fluidization section is connected between the separation section and the air distribution section and provided with the built-in heat exchangers and the partition plate heat exchangers. The built-in heat exchangers can be classified as low-density arranged built-in heat exchangers for drying, high-density arranged built-in heat exchangers for drying and built-in heat exchangers for cooling according to effect and arrangement density. The partition plate heat exchangers can be classified as low-position partition plate heat exchangers and high-position partition plate heat exchangers according to effect and position. The non-uniform air distribution interconnected fluidized bed drying device enables dried materials to be subjected to interconnected fluidization in non-uniform air distribution and regional fluidization modes and has the advantages of being high in fluidization quality, low in energy consumption, reliable in operation and the like.

Description

technical field [0001] The invention belongs to the technical field of dryers, and in particular relates to a non-uniform air distribution serial fluidized bed drying equipment. Background technique [0002] Fluidized bed dryer is a large category of traditional drying equipment, widely used in chemical, petroleum, food, biomedical and other industries, suitable for drying various granular, flake and heat-sensitive materials. The traditional fluidized bed drying equipment has the following defects: (1) Most of the currently used fluidized bed dryers are single-stage fluidized beds. Uneven drying or overheating occurs; (2) The existing fluidized bed drying technology with a built-in heat exchanger hinders the normal fluidization of the drying material due to the unreasonable setting of the buried pipe, especially when the material to be dried has just entered the dryer In addition, the fluidized bed drying technology with a built-in heat exchanger also has problems such as s...
