High performance fluidized bed

Abstract

The invention provides a high performance fluidized bed. The high performance fluidized bed is characterized by comprising a bed body, an air blower, a heat exchanger, an air cooler, a cyclone separator, a water curtain dust remover and an induced draft fan; the air blower is connected with the heat exchanger and the air cooler through pipelines, the lower end of the bed body is provided with a warm air inlet and a cold air inlet, a wind deflector is located inside the bed body, a grating is arranged above the wind deflector, a material baffle is arranged above the grating, a feeding inlet is higher than the top end of the material baffle, the material baffle and the wind deflector are arranged in a staggered mode, and a vibration motor is arranged below the bed body. According to the high performance fluidized bed, a wind shield is arranged at the warm air inlet and the cold air inlet, when the air blower is started, wind can blow the wind shield to be opened, drying is performed, after the air blower is closed, the wind shield is closed, materials inside the bed body are separated from the pipeline below the materials, and equipment is prevented from being damaged.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular to a high-performance fluidized bed. Background technique [0002] Fluidized bed is mainly used for drying and cooling of granular materials and powder materials. The material to be dried is added to the fluidized bed body through the feeder, and the material entering the fluidized bed is in contact with the hot air above the air distribution plate, and after being uniformly and fully mixed, the material particles in the fluidized bed are blown up Suspended in a boiling state, dehydrated and dried, qualified products are discharged from the outlet of the fluidized bed, and the dusty gas is purified by the dust removal device and discharged into the atmosphere by the exhaust fan. The existing fluidized bed generally consists of three sections, and the position of the lower agglomeration is generally set at the end of the fluidized bed, which will cause positive pressure at the outle...

AI Technical Summary

Problems solved by technology

The existing fluidized bed is generally composed of three sections, and the lower agglomeration position is generally set at the end of the fluidized bed, which will cause positive pressure at the outlet of the packaging, and powder dusting phenomenon will occur, and the moisture content of the agglomerated powder cannot be effectively controlled. Will increase product moisture
