Abstract

The invention discloses spray drying equipment for a circulating fluidized bed. According to the spray drying equipment for the circulating fluidized bed, a circulating channel is formed by a fan (1), a circulating pipeline I (2), a dust collector (4), a regulating valve (5), a three-way air inlet joint (6) and a circulating pipeline II (7). An atomizer is arranged in the circulating pipeline II (7). Under the action of the fan (1), air flow enters the circulating channel through an air inlet valve (9) and circularly flows at high speed, a liquid-state material is atomized through the atomizer, enters the circulating channel, goes into a fluidization state under the action of the high-speed air flow, and flows at high speed in the circulating channel, heat exchange and water exchange are quickly performed between the material and the air flow, and wet air is discharged along with air flow separated from the dust collector, so that the liquid-state material can be dried.

Description

technical field [0001] The invention relates to a spray drying equipment. Background technique [0002] Spray drying is a kind of drying that uses an atomizer to disperse a liquid or paste-like material into very fine mist-like particles, and contacts with hot air to remove most of the water in an instant, so that the solid matter in the material can be dried. method. Existing spray drying equipment generally has a drying tower with a large size, which has disadvantages such as complex structure and low thermal efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a circulating fluidized bed spray drying equipment with simple structure and high thermal efficiency. [0004] The technical solution of the present invention is: a circulating fluidized bed spray drying equipment, including fan, circulation pipeline I, dust collector, regulating valve, air inlet tee, circulation pipeline II, the above component...
