The utility model discloses a tube bundle heater for a vibrated
fluidized bed dryer, which belongs to the technical field of vibrated
fluidized bed dryers, solves the problem that heating gas in the tube bundle heater of the conventional vibrated
fluidized bed cannot be fully attached to the outer wall of a
cold air conveying pipeline, and comprises a tube body, a tube head, a tube
tail and an air inlet tube. By arranging the heating mechanism, a traditional conveying path of heated gas is changed, a
wave mode is changed into a threaded movement mode, the
contact time of the heated gas and the outer wall of a pipeline for conveying
cold air can be prolonged, the conveying path of the heated gas in the
pipe body can be prolonged, the heated gas is made to make full and comprehensive contact with the outer wall of the pipeline for conveying the
cold air, and the
heating efficiency is improved. The pipeline fully absorbs heat in the heated gas, the heat conduction effect is more stable, the subsequently heated gas is input into the vibrated fluidized
bed, and materials in the vibrated fluidized
bed can be better dried, so that the stability of equipment during operation is enhanced.
