Drying device for bagasse drying

Abstract

The invention discloses a drying device for bagasse drying. The drying device for bagasse drying comprises a dewatering device, a smashing device and a drying box, the dewatering device comprises a rolling unit and a sucking unit arranged in the rolling unit; the rolling unit comprises a first rolling column and a second rolling column which are equal in size; a first gap used for rolling materials is formed between the first rolling column and the second rolling column; first grooves are formed in the outer surfaces of the rolling columns, and are spirally encircled on the outer surface of abarrel; the annular grooves are in parallel at equal intervals; the smashing device is arranged below the dewatering device, and comprises a funnel-shaped material bin and a stirrer; and the drying box is arranged below the smashing device, and a gas inlet used for introducing hot gas is further formed in the lower portion of the drying box.

Description

technical field [0001] The invention relates to the technical field of bagasse drying, and more specifically, the invention relates to a drying equipment for bagasse drying. Background technique [0002] Bagasse is the dregs left after sugarcane is pressed. It can be used for papermaking, board making, fertilizer or alcohol production, etc. Whether it is papermaking, board making, fertilizer making or storage, it needs to be dried in advance. [0003] The existing drying equipment for bagasse drying is to directly use the flue gas or hot gas discharged from the boiler to heat and dry the bagasse. Such drying equipment or drying methods do not pre-treat the bagasse, and the bagasse containing a large amount of water Directly entering the drying equipment, the evaporation of water will take away a lot of heat, and drying the bagasse will consume a lot of flue gas, so the drying efficiency is not high, and the energy consumption is serious. [0004] There are also some factori...

[0003] The existing drying equipment for bagasse drying is to directly use the flue gas or hot gas discharged from the boiler to heat and dry the bagasse. Such drying equipment or drying methods do not pre-treat the bagasse, and the bagasse containing a large amount of water Directly enter the drying equipment, the evaporation of water will take away a lot of heat, and the drying of bagasse will consume a lot of flue gas, so the drying efficiency is not high, and the energy consumption is serious

[0004] There are also some factories that accumulate bagasse and dry it naturally before drying. Although it can save some costs, the efficiency of natural air drying is low and the drying is uneven. More importantly, the bagasse will ferment and change taste during the accumulation or drying process, reducing the availability of bagasse
